This invention relates, in general, to signage and, in particular, to fixed signage and a method for use of the same that provides visual indications furnishing instructions and guidance at locations undergoing maintenance, construction, or the like.
On railroads, signs are utilized to protect trains, train crews, contractors, and anyone performing work within a railway right-of-way. When a train approaches a location having a sign posted, the sign informs the train crew what, if any, steps need to be taken when passing the area. Railway signs during extensive maintenance and construction may include dozens to hundreds of signs installed along vast sections of track and adjacent roadway. The signs inform train crews and drivers of the conditions and provide guidance that prioritizes safety. During such maintenance and construction, railway workers are frequently assigned the task of covering and uncovering signs temporarily along a distance of track. Typically, railway workers use burlap sacks to cover the signs. Not only is the covering and uncovering labor intensive, but the burlap sacks are difficult to secure in high winds and subject to degradation in the elements. These practices have been in place for decades despite technology improvements in many other areas. As a result, there is a need for improved fixed signs.
It would be advantageous to achieve technology improvements in the area of fixed signs. It would also be desirable to enable an electro-mechanical-based solution that would enable remote management and oversight of fixed signs. To better address one or more of these concerns, a fixed signage and a method for use of the same are disclosed. In one embodiment of the fixed signage, a housing having a window is sized to house a sign therein. A closure assembly, under the power of an actuator, is installed in the housing to support a cover material. The cover material is moveable by a moveable closure member between a fully retracted position whereat the cover material is contained within the housing such that the window is exposed to a fully extended position whereat the cover material covers at least a portion of the window. A command signal may be received via a transceiver to remotely control the actuator and cover material. A sensor within the housing indicates a location of the cover material.
In another embodiment of the fixed signage, a housing having a window is sized to house a sign therein. The sign is secured within the housing and a signifier is visible via the window. The sign is mounted to a post with fasteners secured thereto through the rear of the housing. A closure assembly, under the power of an actuator, is installed in the housing to support a cover material. The cover material is moveable by a moveable closure member between a fully retracted position whereat the cover material is contained within the housing such that the window is exposed to a fully extended position whereat the cover material covers at least a portion of the window. A command signal may be received via a transceiver to remotely control the actuator and cover material. A sensor within the housing indicates a location of the cover material. These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
For a more complete understanding of the features and advantages of the present invention, reference is now made to the detailed description of the invention along with the accompanying figures in which corresponding numerals in the different figures refer to corresponding parts and in which:
While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts, which can be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the present invention.
Referring initially to
As the train 20 approaches the location having the fixed signage 10, for example, the signifier 28 on the sign 26 informs the train crew what, if any, steps need to be taken when passing the area. In this instance, the fixed signage 10 indicates that the train 20 should stop. During maintenance and construction operations as depicted in
Not only does the use of the smart device 42 mitigate the labor required in the covering and uncovering operations, but the fixed signage 10 includes various failsafe measures to ensure appropriate covering and uncovering, e.g., the desired position of the cover material 34 over the sign 26 and window 24. Alternatively, the server 46 may be utilized to remotely actuate the covering or uncovering of the sign 26 via the fixed signage as well as manage the fixed signage. The use of the server 46 also mitigates the labor required in the covering and uncovering operations.
It should be appreciated, however, that the teachings presented herein are not limited to fixed signage related to performing work within a railway right-of-way on a railroad. More generally, the teachings presented herein are applicable to any industry using fixed signage that may be periodically covered and uncovered. Such industries include agricultural, manufacturing, construction, oil and gas, transportation, as well as service industries, including delivery and security. By way of example and not by way of limitation, with respect to the agricultural industry, in forestry, fixed signage may be deployed near and within a logging operation and require periodic covering and uncovering. In the manufacturing industry at a steel plant, signage may be deployed to provide guidance to drivers and the signage may be periodically covered and uncovered. By way of further example, in the road construction industry, the proximity sensors would be particularly beneficial to provide alerts if a vehicle passes a fixed sign when the vehicle should not pass.
More particularly, with respect to the various fail safe measures, which will be discussed in further detail hereinbelow, the fixed signage 10 includes a signal sensor 60 located within the housing 22 to sense a location of the cover material 34. It should be appreciated that the signal sensor 60 may include multiple signal sensors. Also, the fixed signage 10 includes a proximity sensor 62, which may be a rail sensor in some implementations, located within the housing 22. It should be appreciated that the proximity sensor 62 may include multiple proximity sensors. The proximity sensor 62 is oriented toward a sensing location 64 proximate the ground at the railroad track 18. The sensing location 64 is a railway right-of-way sign distance 66 away. The proximity sensor 62 monitors for a railway event, like the train 20 passing the signage 10.

The closure assembly 32 includes a frame 110 that supports the cover material 34, which may be a flexible material. As previously discussed, the flexible material is moveable, under the power of an actuator 112 including actuator units 114, 116 between a fully retracted position whereat the cover material 34 is contained within a pocket 118 of the frame 110, as shown by an arrow 120, to a fully extended position whereat the cover material 34 covers some, as shown by an arrow 122, or all, as shown by an arrow 124, of the window 24.
In the illustrated embodiment, the cover material 34 is engaged with a draw bar 130 at the free end thereof and engaged with a spring biased roller 132 at the other end. The spring biased roller 132 is engaged with integral mounting brackets 134, 136 which form portions of the frame 110, to permit slidable installation and removal of the spring biased roller 132 assembly and the integral mounting brackets 134, 136 in mating engagement within the pocket 118 of the frame 110. The cover material 34 is moveable by a pair of moveable closure members 138, 140 contained within the integral mounting brackets 134, 136 under the power of the respective actuator unit 114, 116.
A door 150 in the front 80 of the housing 22 provides access to an electronics compartment 152, which may house a processor 154 (
Referring now to
The transceiver 160 is associated with the housing 22 and communicatively disposed with the busing architecture 172. As shown, the transceiver 160 may be internal, external, or a combination thereof to the housing 22. Further, the transceiver 160 may be a transmitter/receiver, receiver, or an antenna for example. Communication with various electronic devices, such as the smart device 42 or the server 46, and the transceiver 160 may be enabled by a variety of wireless methodologies employed by the transceiver 160, including 802.11, 3G, 4G, Edge, WiFi, ZigBee, near field communications (NFC), Bluetooth low energy and Bluetooth, for example. Also, infrared (IR) may be utilized.
The memory 156 and the storage 158 are accessible to the processor 154 and include processor-executable instructions that, when executed, cause the processor 154 to execute a series of operations. In one implementation of the processor-executable instructions, the processor 154 is caused to receive a command signal via the transceiver 160 and, responsive thereto, control the actuator 112 via the actuator input/output 162 per the command signal. The command signal may include a command to lower the cover material 34 over the sign 26 such that the cover material 34 is in a fully extended position. On the other hand, the command signal may include a command to raise the cover material 34 off of the sign 26 such that the cover material 34 is in a fully retracted position. The processor-executable instructions may then cause the processor 154 to receive state data from the actuator 112 via the actuator input/output 162. The state data may indicate the state of the actuator 112, with a known correlation existing between the state of the actuator 112 and the position of the cover material 34 relative to the sign.
The processor 154 may then receive sensor data from the signal sensor 60. The sensor data indicates the location of the cover material 34. The process may also receive event data from the proximity sensor 62. The event data indicates a railway event, such as the train 20 passing. The processor-executable instructions may then send a status report via the transceiver 160 to the smart device 42 or the server 46, for example. The status report may include the state data, the sensor data, the event data, or a subset thereof. The fixed signage 10 may send various data in the form of the status report or otherwise, and send the various data periodically, continuously, or in response to a request from the smart device 42 or the server 46, for example.
That is, in another implementation of the processor-executable instructions 178, the processor 154 is caused to receive a status request via the transceiver 160 from the smart device 42 or the server 46, for example. In response thereto, the fixed signage 10 sends the status report via the transceiver 160 to the smart device 42 or the server 46. The status report may include the state data, the sensor data, the event data, or a subset thereof. In a still further implementation of the processor-executable instructions, the processor 154 is caused to, in response to a railway event, send the status report via the transceiver 160. As previously discussed, the status report may include the state data, the sensor data, the event data, or a subset thereof.
Referring now to
The proximity sensor 62 monitors the railroad track 18 for a railway event, such as the passing of the train 20, and the proximity sensor 62 sends event data 192 to the processor 154 and the memory 156. The event data 192, such as the passing of the train 20, may provide the railway worker 40 with confirmation that the fixed signage 10 and train crew are operating, correcting, or the event data 192 may provide the railway work with confirmation of a problem, such as the train 20 passing signage indicating “STOP.” As shown, the actuator input/output 162 monitors the state of the actuator 112 and reports state data 194 to the processor 154 and the memory 156. Similarly, the signal sensor 60 monitors the movement and position of the cover material 34 and reports sensor data 196 to the processor 154 and the memory 156. The event data 192, state data 194, and the sensor data 196 may then be provided in a status report 198 via the transceiver 160 to the smart device 42.
In further operations, the smart device 42 sends a status request 200 to the fixed signage 10. Responsive to the status request 200, the fixed signage 10 may utilize the actuator input/output 162 to monitor the state of the actuator 112 and report state data 202 to the processor 154 and the memory 156. The signal sensor 60 may be utilized to monitor the movement and position of the cover material 34 and report sensor data 204 to the processor 154 and the memory 156. Similarly, the proximity sensor 62 may be utilized to provide event data 206. The state data 202, the sensor data 204, and the event data 206 may then be provided in a status report 208 via the transceiver 160 to the smart device 42.
