The present invention relates generally to fire alarm and security system peripheral devices. More particularly, the present invention relates to a system and method of near field communication enabled programming of such peripheral devices.
Peripheral devices in fire alarm and security systems must be configured. However, known configuration systems and methods require system power and a programming device or mechanical switch to configure the peripheral device. This is often undesirable.
In view of the above, there is a continuing, ongoing need for an improved system and method to configure or program peripheral devices.
While this invention is susceptible of an embodiment in many different forms, there are shown in the drawings and will be described herein in detail specific embodiments thereof with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention. It is not intended to limit the invention to the specific illustrated embodiments.
Embodiments disclosed herein include a system and method of near field communication enabled programming of peripheral devices in fire alarm and security systems. In some embodiments, the systems and methods disclosed herein can securely configure and program a peripheral device without the need for system power or mechanical switches. Accordingly, the systems and methods disclosed herein can reduce cost and provide benefits that include, but are not limited to, fast configuration, automated configuration, increased access to information, downloaded software applications, and initial configuration of a device during production. For example, in some embodiments, a single peripheral device with a single SKU can be configured in one of a plurality of different ways without the need for a powered fixture.
In accordance with the systems and methods disclosed herein, in some embodiments, a peripheral device can be configured without removing the device from its packaging carton, a peripheral device can provide visual feedback of configuration information, a peripheral device can be configured without applying system power, all or a portion of a peripheral device can be powered using near field communication (NFC) technology, a memory device in a peripheral device can be used to store or read configuration data, and/or a microcontroller in a peripheral device can receive power to configure or read the device's memory.
In some embodiments, a peripheral device as disclosed herein can include at least a memory device, a microcontroller, and a near field communication interface. For example, the near field communication interface can harvest or receive energy or power for powering the device during device configuration or programming. That is, the peripheral device need not include or receive switches, system power, or battery power for device configuration or programming.
In some embodiments, a peripheral device as disclosed herein can include a display device, for example, an electronic paper display or other indicator that can display a static text, image, and/or color indefinitely without using electricity. In some embodiments, such a display device can be visible while the peripheral device is contained within its packaging carton and in some embodiments, the information on the display device can include configuration information and feedback.
In some embodiments of operation, a near field configuration device can be placed within a predetermined distance of a peripheral device as disclosed herein and can communicate with the peripheral device using near field communication technology. While in communication, the near field configuration device can provide power to the peripheral device, via the near field communication, for configuring the device. Accordingly, the near field configuration device can communicate with the peripheral device with or without opening the peripheral device's packaging carton and with or without applying system or battery power to the peripheral device.
In some embodiments, the near field configuration device can be used to perform any or all of the following exemplary configuration functions on the peripheral device, without limitation: setting the peripheral device address, assigning the peripheral device to a group or zone, assigning control of the peripheral device by event functions, assigning peripheral device output power levels, assigning peripheral device output functions, assigning peripheral device input functions, assigning peripheral device wiring configuration, and/or setting peripheral device detection thresholds and sensitivities.
In some embodiments, the near field configuration device can include any or all of the following exemplary software applications or programmed algorithms that can be executed during configuration of the peripheral device, without limitation: automatically incrementing the target device address, for example, the peripheral device address, when moving from one device to the next, and/or automatically assigning location information, zone information, or wireless mesh parent child relationships.
In some embodiments, the near field configuration device can receive or extract data from the peripheral device with which the configuration device is communicating. For example, extracted information can be used for diagnostic purposes or to perform real-time diagnostic testing on the peripheral device.
In some embodiments, one or both of the near field configuration device and the peripheral device can include a software application with a security feature for limiting access to the peripheral device to one or a particular group of configuration devices following initial configuration of the peripheral device. In some embodiments, the near field configuration device can contain a software application that enables the grouping of peripheral devices so that a group of peripheral devices can be mapped to one or more groups of system devices.
The control circuitry 120 can include one or more programmable processors 120a and executable control software 120b as would be understood by one of ordinary skill in the art. The executable control software 120b can be stored on a transitory or non-transitory computer readable medium, including, but not limited to, local computer memory, RAM, optical storage media, magnetic storage media, flash memory, and the like.
As seen in
In some embodiments, the executable control software 120b can include software applications or programmed algorithms that can be executed during communication with the near field configuration device 200, for example, when the peripheral device 100 is being powered via the near field communication with the configuration device 200. Similarly, in some embodiments, the executable control software 220b can include software applications or programmed algorithms that can be executed during communication with and configuration of the peripheral device 100. Furthermore, in some embodiments, the executable control software 220b can include software applications that can be transmitted or downloaded to the peripheral device 100 when the near field configuration device 200 is communicating with the peripheral device 100. In some embodiments, such software applications or programmed algorithms can include instructions on grouping devices.
When communicating via near field communication technology, the near field configuration device 200 can transmit a signal, via the communication interface 210, to the peripheral device 100, which can receive the signal, via the communication interface 130, and extract power therefrom. For example, upon receiving the signal from the near field configuration device 200, all or a portion of the peripheral device 100, for example, at least the control circuitry 120, can be powered by the signal and the contents thereof.
The signal received from the near field configuration device 200 can include configuration data, information, or instructions, and in some embodiments, the peripheral device 100 can store such configuration data, information, or instructions in the memory device 110. Furthermore, upon such receipt or storage, the display device 140 can display a predetermined indicator regarding the configuration status of the peripheral device 100.
In some embodiments, the peripheral device 100 can also transmit a signal, via the communication interface 130, to the near field configuration device 200 to provide the configuration device 200, via the communication interface 210, with diagnostic information regarding the peripheral device 100 and the configuration thereof. In some embodiments, the peripheral device 100 can transmit the signal with such information responsive to the near field configuration device 200 or a signal or instructions received therefrom.
In some embodiments, the executable control software 120b and/or the executable control software 220b can include a security feature as explained above.
