The present disclosure relates to refrigeration, HVAC, and other building systems and, more particularly, to location-based information retrieval, viewing, and diagnostics for refrigeration, HVAC, and other building systems.
The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
Refrigeration systems are an essential part of many commercial buildings and dwellings. For example, food retailers may rely on refrigeration systems to ensure the quality and safety of food products. Many other businesses may have products or materials that must be refrigerated or maintained at a lowered temperature. HVAC systems allow people to remain comfortable where they shop, work or live.
Refrigeration system operation, however, can represent a significant portion of a business' operating costs. As such, it may be beneficial for refrigeration system users to remotely monitor the performance and energy consumption of the refrigeration systems to detect and diagnose any performance issues so that maintenance can be performed to maximize efficiency and reduce operational costs.

With reference to
Each compressor 12 has an associated compressor controller 20 that monitors and controls operation of the compressor 12. For example, the compressor controller 20 may monitor electric power, voltage, and/or current delivered to the compressor 12 with a power sensor, a voltage sensor, and/or a current sensor. Further, the compressor controller 20 may also monitor suction or discharge temperatures or pressures of the compressor 12 with suction or discharge temperature or pressure sensors. For example, a discharge outlet of each compressor 12 can include a respective discharge temperature sensor 22. A discharge pressure sensor can be used in addition to, or in place of, the discharge temperature sensor 22. An input to the suction manifold 16 can include both a suction pressure sensor 24 and a suction temperature sensor 26. Further, a discharge outlet of the discharge header 18 can include an associated discharge pressure sensor 28. A discharge temperature sensor can be used in addition to, or in place of, the discharge pressure sensor 28. As described in further detail below, the various sensors can be implemented for monitoring performance and diagnosing the compressors 12 in the compressor rack 14.
A rack controller 30 may monitor and control operation of the compressor rack 14 via communication with each of the compressor controllers 20. For example, the rack controller 30 may instruct individual compressors 12 to turn on or turn off through communication with the compressor controllers 20. Additionally, the rack controller 30 may instruct variable capacity compressors to increase or decrease capacity through communication with the compressor controllers 20. In addition, the rack controller 30 may receive data indicating the electric power, voltage, and/or current delivered to each of the compressors 12 from the compressor controllers 20. Further, the rack controller 30 may also receive data indicating the suction or discharge temperatures or pressures of each of the compressors 12 from the compressor controllers 20. Additionally or alternatively, the rack controller 30 may communicate directly with the suction or discharge temperature or pressure sensors to receive such data. Additionally, the rack controller 30 may be in communication with other suction and discharge temperature and pressure sensors, including, for example, discharge pressure sensor 28, suction pressure sensor 24, and suction temperature sensor 26.
Electric power may be delivered to the compressor rack 14 from a power supply 32 for distribution to the individual compressors 12. A rack power sensor 34 may sense the amount of power delivered to the compressor rack 14. A current sensor or a voltage sensor may be used in place of or in addition to the rack power sensor 34. The rack controller 30 may communicate with the rack power sensor 34 and monitor the amount of power delivered to the compressor rack 14. Alternatively, the rack power sensor 34 may be omitted and the total power delivered to the compressor rack 14 may be determined based on the power data for the power delivered to each of the individual compressors 12 as determined by the compressor controllers 20.
The compressor rack 14 compresses refrigerant vapor that is delivered to a condensing unit 36 having a condenser 38 where the refrigerant vapor is liquefied at high pressure. Condenser fans 40 may enable improved heat transfer from the condenser 38. The condensing unit 36 can include an associated ambient temperature sensor 42, a condenser temperature sensor 44, and/or a condenser discharge pressure sensor 46. Each of the condenser fans 40 may include a condenser fan power sensor 47 that senses the amount of power delivered to each of the condenser fans 40. A current sensor or a voltage sensor may be used in place of or in addition to the condenser fan power sensor 47.
A condensing unit controller 48 may monitor and control operation of the condenser fans 40. For example, the condensing unit controller 48 may turn on or turn off individual condenser fans 40 and/or increase or decrease capacity of any variable speed condenser fans 40. In addition, the condensing unit controller 48 may receive data indicating the electric power delivered to each of the condenser fans 40 through communication with the condenser fan power sensors 47. Additionally, the condensing unit controller 48 may be in communication with the other condensing unit sensors, including, for example, the ambient temperature sensor 42, the condenser temperature sensor 44, and the condenser discharge pressure sensor 46.
Electric power may be delivered to the condensing unit 36 from the power supply 32 for distribution to the individual condenser fans 40. A condensing unit power sensor 50 may sense the amount of power delivered to the condensing unit 36. A current sensor or a voltage sensor may be used in place of or in addition to the condensing unit power sensor 50. The condensing unit controller 48 may communicate with the condensing unit power sensor 50 and monitor the amount of power delivered to the condensing unit 36.
The high-pressure liquid refrigerant from the condensing unit 36 may be delivered to refrigeration cases 52. For example, refrigeration cases 52 may include a group 54 of refrigeration cases 52. The refrigeration cases 52 may be refrigerated or frozen food cases at a grocery store, for example. Each refrigeration case 52 may include an evaporator 56 and an expansion valve 58 for controlling the superheat of the refrigerant and an evaporator temperature sensor 61. The refrigerant passes through the expansion valve 58 where a pressure drop causes the high pressure liquid refrigerant to achieve a lower pressure combination of liquid and vapor. As hot air from the refrigeration case 52 moves across the evaporator 56, the low pressure liquid turns into gas. The low pressure gas is then delivered back to the compressor rack 14, where the refrigeration cycle starts again.
A case controller 62 may monitor and control operation of the evaporators 56 and/or the expansion valves 58. For example, the case controller 62 may turn on or turn off evaporator fans of the evaporators 54 and/or increase or decrease capacity of any variable speed evaporator fans. The case controller 62 may be in communication with the evaporator temperature sensor 61 and receive evaporator temperature data.
Electric power may be delivered to the group 54 of refrigeration cases 52 from the power supply 32 for distribution to the individual condenser fans 40. A refrigeration case power sensor 60 may sense the amount of power delivered to the group 54 of refrigeration cases 52. A current sensor or a voltage sensor may be used in place of or in addition to the refrigeration case power sensor 60. The case controller 62 may communicate with the refrigeration case power sensor 60 and monitor the amount of power delivered to the group 54 of refrigeration cases 52.
As discussed above, while
A system controller 70 monitors and controls operation of the entire refrigeration system 10 through communication with each of the rack controller 30, condensing unit controller 48, and the case controller 62. Alternatively, the rack controller 30, condensing unit controller 48, and/or case controller 62 could be omitted and the system controller 70 could directly control the compressor rack 14, condensing unit 36, and/or group 54 of refrigeration cases 52. The system controller 70 can receive the operation data of the refrigeration system 10, as sensed by the various sensors, through communication with the rack controller 30, condensing unit controller 48, and/or case controller 62. For example, the system controller can receive data regarding the various temperatures and pressures of the system and regarding electric power, current, and/or voltage delivered to the various system components. Alternatively, some or all of the various sensors may be configured to communicate directly with the system controller 70. For example, the ambient temperature sensor 42 may communicate directly with the system controller 70 and provide ambient temperature data.
The system controller 70 may coordinate operation of the refrigeration system, for example, by increasing or decreasing capacity of various system components. For example, the system controller 70 may instruct the rack controller 30 to increase or decrease capacity by activating or deactivating a compressor 12 or by increasing or decreasing capacity of a variable capacity compressor. The system controller 70 may instruct the condensing unit controller 48 to increase or decrease condensing unit capacity by activating or deactivating the condenser fan 40 or by increasing or decreasing a speed of a variable speed condenser fan. The system controller 70 may instruct the case controller 62 to increase or decrease evaporator capacity by activating or deactivating an evaporator fan of an evaporator 56 or by increasing or decreasing a speed of a variable speed evaporator fan. The system controller 70 may include a computer-readable medium, such as a volatile or non-volatile memory, to store instructions executable by a processor to carry out the functionality described herein to monitor and control operation of the refrigeration system 10.
The system controller 70 may be, for example, an E2 RX refrigeration controller available from Emerson Climate Technologies Retail Solutions, Inc. of Kennesaw, Ga. If the system is an HVAC system instead of a refrigeration system, the system controller 70 may be, for example, an E2 BX HVAC and lighting controller also available from Emerson Climate Technologies Retail Solutions, Inc. of Kennesaw, Ga. Further, any other type of programmable controller that may be programmed with the functionality described in the present disclosure can also be used.
The system controller 70 can monitor the actual power consumption of the refrigeration system 10, including the compressor rack 14, the condensing unit 36, and the refrigeration cases 52, and compare the actual power consumption of the refrigeration system 10 with a predicted power consumption or with a benchmark power consumption for the refrigeration system 10 to determine a health indicator score for the refrigeration system 10 and/or for individual refrigeration system components. Additionally or alternatively, the system controller 70 can monitor the temperatures and pressures of the refrigeration system 10, including the compressor rack 14, the condensing unit 36, and the refrigeration cases 52, and compare the temperatures and/or pressures with expected temperatures and/or pressures, based, for example, on historical data to determine a health indicator score for the refrigeration system 10 and/or for individual refrigeration system components.
The system controller 70 may be in communication with a server 72. The server 72 may be, for example, configured to communicate with the system controller 70 via a remote link such as, for example, a Wi-Fi link, a Bluetooth link, a local area network at the facility location of the refrigeration systems, or a wide area network, such as the internet. Alternatively, the server 72 may be a part of the system controller 70 and may be configured to communicate with each other via a hardwire link. As an example, the system controller 70 including the server 72 may be implemented in an E2 BX HVAC and lighting controller available from Emerson Climate Technologies Retail Solutions, Inc. of Kennesaw, Ga. Alternatively, the server 72 may be implemented in a Site Supervisor controller available from Emerson Climate Technologies Retail Solutions, Inc. of Kennesaw, Ga.
The server 72 may communicate with the system controller 70 to receive and store configuration and operational data of the refrigeration system 10, including, for example, energy or performance data of the refrigeration system 10. The server 72 may further include a computer-readable medium, such as a volatile or non-volatile memory component, so that the configuration and operational data of the refrigeration system 10 may be received and stored on the server 72.
The server 72 may be in communication with a mobile device 80. The mobile device 80 may be, for example, a laptop, a tablet, a smartphone or other computing device with communication/networking capabilities. Alternatively, the mobile device 80 may be a desktop computer. The mobile device 80 may communicate with the server 72 via a local area network at the facility location of the refrigeration system 10. The mobile device 80 may also communicate with the server 72 via a wide area network, such as the internet.
The mobile device 80 may be configured to receive and display stored configuration and operational data from the server 72 for one or more refrigeration or HVAC systems or one or more components thereof, including, for example, configuration and/or operational data, such as energy or performance data for the refrigeration or HVAC systems or components. The mobile device 80 may display the stored data from the server 72 using an application (App) on the mobile device 80 that is configured to display the stored data on a graphic user interface, such as a touchscreen, of the mobile device 80.
The mobile device 80 may be in communication with the system controller 70. The mobile device 80 may communicate with the system controller 70 via a local area network at the facility location of the refrigeration system 10 or a wide area network, such as the internet. The mobile device 80 may be configured to remotely monitor the operation of the system controller 70.
The mobile device 80 may be in communication with a plurality of beacons 74, which may be coupled to and associated with individual systems or components, including, for example, each of the refrigeration cases 52, the condensing unit 36, and the compressor rack 14. The beacons 74 may be, for example, configured to communicate with the mobile device 80 via a remote link such as, for example, a Bluetooth link.
The beacon 74 may be configured to broadcast/communicate identifying information for the associated system or component to the mobile device 80. For example, the beacon 74 may communicate an identification number for the associated system or component and/or the physical location of the associated system or component, such as the refrigeration case 52, the condensing unit 36, and/or the compressor rack 14, to the mobile device 80. Alternatively or additionally, if the mobile device 80 receives a Bluetooth signal from the beacon 74, the mobile device 80 may be configured to, using an App or an operating system of the mobile device 80, execute a location-based action on the mobile device, such as retrieving configuration data, operational data, and/or diagnostics data from the server 72 of the corresponding system or component, for example the refrigeration case 52, condensing unit 36, and/or compressor rack 14, and displaying the configuration data, operational data, and/or diagnostics on the mobile device 80. For example, as discussed in further detail below, a technician may be able to move around a location, such as a retail location with multiple pieces of equipment, while holding the mobile device 80. The App running on the mobile device 80 can then receive the nearest beacon and automatically provide confirmation and/or status information for that particular piece of equipment, for example a refrigeration case or other equipment. Alternatively, the technician could manually instruct the App running on the mobile device 80 to provide the confirmation and/or status information for that particular piece of equipment.
With reference to
Systems and methods for performing the diagnostics analysis on the refrigeration systems at 204 are described in the commonly assigned U.S. patent application Ser. No. 15/197,169, U.S. Pub. No. 2017/0089598, titled “Maintenance and Diagnostics for a Refrigeration System,” which is incorporated herein by reference in its entirety.
At 206, the diagnostic analysis performed on the refrigeration unit is stored on a data store. For example, the diagnostic analysis may be stored on the computer-readable medium, such as the non-volatile memory on the server 72. The diagnostic analysis may be communicated to the server 72 via a remote link such as, for example, a local area network at the facility location of the refrigeration system, or a wide area network, such as the internet. At 208, the control algorithm 200 ends.
With reference to
Meanwhile, the beacon 74 may transmit the identification information and/or physical location data of the refrigeration case 52 via a Bluetooth signal. The mobile device 80, which may be a smartphone in this embodiment, is configured to receive, for example, Bluetooth signals from the beacon 74. Once the mobile device 80 detects and receives the signal, for example a Bluetooth signal, from the beacon 74, the mobile device 80 is configured to, using an App, retrieve the configuration, performance, and/or operational data from the server 72 of the refrigeration case 52 and subsequently display the configuration, performance, and operational data on a display of the mobile device 80. While the beacon 74 is described as utilizing a Bluetooth signal, other signals could alternatively be use, such as radio frequency (RF) signals using alternative protocols, for example a Wi-Fi signal or a ZigBee signal.
The system controller 70 may include a user interface to view configuration, performance, and/or operational data for individual systems or components. For example, the system controller 70 may include a user interface that displays, and allows for modifications of, various setpoints and other configuration settings for individual systems or components. The mobile device 80 can be configured to, using the App, display the same, or a similar, user interface that is used and displayed by the system controller 70. As such, a user of the mobile device 80 may be able to view configuration, performance, and/or operational data of a particular system or component, and may be able to modify particular setpoints or other configuration settings for the particular system or component, as if the user were located at the system controller 70 and using the user interface of the system controller 70.
With reference to
The default app state of the App is shown on a display 82 of the mobile device 80. The App may be set to the default app state when the App is initialized by opening the App on the mobile device 80. The default app state is configured to provide an operator of the mobile device 80 the capability to detect refrigeration or HVAC systems located within a building or dwelling. For example, the default app state may provide a “Search for Cases” button 84 on the display 82 of the mobile device 80. Accordingly, once the operator selects button 84, as shown by a cartoon hand in
With reference to
The search results app state may be configured to populate a table 85 with a list of detected systems or components, such as compressor racks 14, condensing units 36, and refrigeration cases 52, based on the search instruction or query performed in the default app state. For example, after selecting the “Search for Cases” button 84 in the default app state, the mobile device 80 may detect Bluetooth signals from the beacons 74 of two refrigeration cases 52, which are labeled and displayed as refrigeration case #1 and #2 buttons 86-1 and 86-2 within the table 85, respectively.
Additionally, the search results app state may be configured to allow an operator of the mobile device 80 to repeat the search query. For example, if the operator is standing next to the refrigeration case 52, and the search result app state does not display any refrigeration cases 52 in the table 85, the operator has the ability to repeat the search query by selecting the “Search for Cases” button 84 on the graphic user interface of the mobile device 80.
The search app state may be configured to allow an operator of the mobile device 80 to view a diagnostic report of a detected refrigeration or HVAC system. For example, the operator may select the “Refrigeration Case #1” button 86-1 to view the diagnostic report of that refrigeration case 52, as shown by the cartoon hand in
With reference to
The diagnostic report app state may be configured to display a variety of system diagnostics, including: a health indicator score for the refrigeration system and/or a refrigeration system component; a predicted power consumption based on performance coefficients for the refrigeration system components and operational data for the refrigeration system; a benchmark power consumption based on the refrigeration system performance during a predetermined time period, such as an initialization period; a floodback condition of the refrigeration system; and a prediction of a performance or capacity issue for a future time period.
Additionally or alternatively, the diagnostic report app state may be configured to allow an operator to perform automatic setup operations for system components based on retrieved component information.
A “Back” button 88 on the display 82 of the mobile device may be configured to allow the operator to return to either the default app state or the search results app state. The operator of the mobile device 80 may select this button if he or she has selected the wrong refrigeration or HVAC unit, has reviewed the diagnostic report and performed any automatic setup operations for the system, or desires to set the App to the default app state.
With reference to
At 306, the operator selects the “Search for Cases” button 84 on the display 82, and in response, the mobile device 80 is configured to search for refrigeration system components. The mobile device 80 may begin to search for refrigeration system components by attempting to communicate with the refrigeration system components via a Bluetooth or Wi-Fi link. Alternatively, the App may be configured to automatically search for the refrigeration system components as soon as the App has been initialized by the user.
At 308, the control algorithm 300 determines whether a refrigeration system component has been detected. If the control algorithm 300 detects a refrigeration system component within its range, it proceeds to 310. Otherwise, the control algorithm 300 transfers to 310 and provides an interface on the display 82 that instructs the operator that no refrigeration system component was found. Then, the control algorithm 300 returns to 306 and repeats the search process until a refrigeration unit is detected.
At 312, the control algorithm 300 populates the table 85 on the display 82 of the mobile device 80 with a list of the detected refrigeration units. The table 85, as described above, may be populated during the search results app state. At 314, the operator of the mobile device 80 selects a refrigeration unit from the table 85. At 316, the user of the mobile device 80 is provided an interface and/or diagnostic report associated with the selected refrigeration system component. As described above, the interface and/or diagnostic report may be provided on the display 82 of the mobile device 80 at the diagnostic report app state. Alternatively, the diagnostic report may be provided at the second App state by displaying the diagnostic report underneath the selected refrigeration unit and re-indexing the remaining detected units on the table 85 accordingly. At 318, the control algorithm 300 ends.
Once the interface is displayed on the mobile device 80, the mobile device 80 may receive input from the user via the touch screen, for example, to modify configuration data, such as setpoints for the associated refrigeration system component. The modifications can then be communicated from the mobile device 80 to the server 72 and then to the system controller 70. The system controller 70 can then update the configuration data settings for the refrigeration system and the associated refrigeration system component in particular so that the system operates with the new configuration setting or settings. In this way, a user of the mobile device 80 can view and modify configuration data for a particular refrigeration system component without having to enter such modifications directly into the system controller 70 or a particular component controller, such as the rack controller 30, case controller 62, condensing unit controller 48, and/or compressor controller 20.

The mobile device 80 may be configured to retrieve identifying information and/or physical location data of the refrigeration case 52 using a computer vision system or other system of the like located within the mobile device 80. The mobile device 80, which may be a smartphone with a camera 89, may be configured to retrieve identifying information and/or physical location data of the refrigeration case 52 when the camera 89 of the mobile device 80 captures an image of the refrigeration case 52 or other indicia associated with the refrigeration case 52 (e.g., a refrigeration rack, a lighting panel, and/or a light fixture associated with the respective refrigeration case 52). Once an image is captured by the camera 89, the mobile device 80 may be configured to, using an App that is configured to perform computer vision algorithms, process and analyze the image, thereby allowing the mobile device 80 to determine which refrigeration case 52 of the refrigeration system is being detected by the mobile device 80. For example, the App may analyze the image of the equipment and identify the particular piece of equipment based on its shape, size, configuration, and/or using other identifying indicia on or associated with the piece of equipment. Additionally or alternatively, the App may analyze the image of the equipment and identify the particular piece of equipment based on an ID tag (e.g., a bar code or a series of characters, letters, or numbers that are unique for each individual refrigeration case 52). Subsequently, the mobile device 80 may be configured to display the configuration, performance, and operational data of the detected refrigeration case 52 on a display of the mobile device 80.

The default app state of the App is shown on the display 82 of the mobile device 80. The App may be set to the default app state when the App is initialized by opening the App on the mobile device 80. The default app state is configured to provide an operator of the mobile device 80 an interface to capture an image or scan an ID tag of refrigeration or HVAC systems located within a building or dwelling. For example, the default app state may provide a “Capture Image of Case” button 90 on the display 82 of the mobile device 80. Accordingly, once the operator selects button 90, as shown by a cartoon hand in

The image capture app state may be configured to provide the user the capability to capture an image of the refrigeration or HVAC system. As an example, a camera button 93 may be configured to, in response to being selected by the user, activate the camera 89 and capture an image of the refrigeration case 52. Subsequently, the App may analyze the image of the equipment and identify the particular piece of equipment based on its shape, size, configuration, and/or using other identifying indicia on or associated with the piece of equipment. In response to identifying the particular piece of equipment, the App may be set to the diagnostic report app state, as described below.
Additionally or alternatively, the image capture app state may include elements on the display 82 that assist the user in capturing the image. As an example, the image capture app state may include text instructions that assist the user in capturing an image of the refrigeration or HVAC system and thus enable the App to identify the respective piece of equipment. Specifically, the display 82 may provide textual instructions that instruct the user to align the bottom corners of the refrigeration case with dashed reference lines 94, as shown in

The diagnostic report app state may be configured to display a variety of system diagnostics, including: a health indicator score for the refrigeration system and/or a refrigeration system component; a predicted power consumption based on performance coefficients for the refrigeration system components and operational data for the refrigeration system; a benchmark power consumption based on the refrigeration system performance during a predetermined time period, such as an initialization period; a floodback condition of the refrigeration system; and a prediction of a performance or capacity issue for a future time period.
Additionally or alternatively, the diagnostic report app state may be configured to allow an operator to perform automatic setup operations for system components based on retrieved component information.
The “Back” button 88 on the display 82 of the mobile device may be configured to allow the operator to return to either the default app state. The operator of the mobile device 80 may select this button if he or she has selected the wrong refrigeration or HVAC unit, has reviewed the diagnostic report and performed any automatic setup operations for the system, or desires to set the App to the default app state.

At 406, the control algorithm 400 selects a refrigeration case identification method. As an example, the user may select the “Capture Image of Case” button 90 or the “Scan Case ID” button 92 in order to determine the method of identification. At 408, the control algorithm 400 determines whether the user selected the ID tag option (i.e., button 92). If so, the control algorithm 400 proceeds to 410; otherwise, the control algorithm 400 proceeds to 414. At 410, the mobile device 80 provides an interface instructing the user to align the case ID tag with the dashed reference box 96, and at 412, the user aligns the case ID tag with the dashed reference box 96. At 414, the mobile device 80 provides an interface instructing the user to align the refrigeration case with dashed reference lines 94, and at 416, the user aligns the bottom corners of the refrigeration case with the dashed reference lines 94.
At 418, the control algorithm 400 searches for matching refrigeration cases in, for example, the server 72 that is in communication with the mobile device 80.

If so, the control algorithm 400 proceeds to 424; otherwise, the control algorithm 400 proceeds to 422. At 422, the control algorithm 400 provides, using the mobile device 80, an interface instructing the user that no refrigeration case corresponding to the image or the ID tag of the refrigeration case was found and then proceeds to 406. At 424, the control algorithm 400, using the mobile device 80, provides an interface and/or diagnostic report associated with the identified refrigeration system component. As described above, the interface and/or diagnostic report may be provided on the display 82 of the mobile device 80 at the diagnostic report app state. At 426, the control algorithm 400 ends.
Once the interface is displayed on the mobile device 80, the mobile device 80 may receive input from the user via the touch screen, for example, to modify configuration data, such as setpoints for the associated refrigeration system component. The modifications can then be communicated from the mobile device 80 to the server 72 and then to the system controller 70. The system controller 70 can then update the configuration data settings for the refrigeration system and the associated refrigeration system component in particular so that the system operates with the new configuration setting or settings. In this way, a user of the mobile device 80 can view and modify configuration data for a particular refrigeration system component without having to enter such modifications directly into the system controller 70 or a particular component controller, such as the rack controller 30, case controller 62, condensing unit controller 48, and/or compressor controller 20.

The reference transceiver system 100 is configured to receive a location signal from each of the beacons 74 of the respective refrigeration cases 52 and from the mobile device 80. The location signals include the identification information and/or physical location data of each of the refrigeration cases 52 and the mobile device 80.
In response to the reference transceiver system 100 receiving the location signals, a reference transceiver controller 102, which may include a processor that is configured to execute instructions stored in a non-transitory memory, determines the position of each of the refrigeration cases 52 and the mobile device 80. The reference transceiver controller 102 may be configured to determine the position of each refrigeration case 52 and the mobile device 80 based on a received signal strength of each signal (e.g., a power ratio in decibels of the reference signals (dBm), a power spectral density of the reference signals (dBm/MHz), and/or a bit error rate (BER) of the location signal) and/or an angle of arrival (AoA) of each location signal.
Then, the reference transceiver controller 102 may identify the nearest refrigeration case with respect to the operator based on the location of each refrigeration case 52 and the mobile device 80. As an example and as shown in

At 516, the control algorithm 500, using the reference transceiver controller 102, identifies the nearest refrigeration case based on the location of the mobile device 80 and of each the refrigeration cases 52. At 518, the control algorithm 500 determines whether the identified nearest refrigeration case is within a threshold distance. As an example, the threshold distance may be set at a value corresponding to a maximum distance that one would be able to see the respective refrigeration case 52 without any obstruction to his or her view or without any visual aids, thereby preventing the operator from identifying the refrigeration case 52 of the building that he or she cannot readily locate. If the identified nearest refrigeration case 52 is within the threshold distance, the control algorithm 500 proceeds to 522; otherwise, the control algorithm 500 proceeds to 520 and provides an interface on the mobile device 80 instructing the operator that no refrigeration case 52 was found.

The location of each of the refrigeration cases 52 may be set or determined during a calibration process of the location-based diagnostic view system. Additionally or alternatively, the location data of the corresponding refrigeration case 52 may be updated and stored on the server in response to the location of the corresponding refrigeration case 52 changing to a second value that is different from the value set during the calibration process.
