Description

Technical Field

[0001] The utility model belongs to the technical field of electronic circuits, and particularly relates to a test device for the automatic addressing function of a fire detector in an energy storage cabinet. Background Art

[0002] In recent years, multiple energy storage system fires that have occurred at home and abroad have attracted widespread attention to lithium battery energy storage systems. Once an energy storage system fire occurs, it will cause significant property losses. In order to effectively reduce fire losses, under the basic principle of "early detection and early disposal", fire detectors for energy storage cabinets have emerged as the times require. Fire detectors for energy storage cabinets can achieve fire detection of energy storage cabinets in advance before a fire occurs, and have the advantages of fast implementation speed, high sensitivity, and low cost, so they are widely used. However, currently, when producing and applying fire detectors for energy storage cabinets, there is still a lack of a more effective automatic addressing function test device. Therefore, it is possible that the automatic addressing function problem is only discovered after the detector is installed on the energy storage cabinet and debugged, which affects its deployment and use and causes a waste of time cost. Summary of the Utility Model

[0041] Embodiment:

[0042] This embodiment provides a test device for the automatic addressing function of a fire detector in an energy storage cabinet, as shown in Figure 1As shown, it includes a key module, a main controller, an addressing circuit, a communication circuit, an indication module, and a power supply module. The main controller is respectively connected to the key module, the addressing circuit, the communication circuit, and the indication module. The addressing circuit and the communication circuit are respectively connected to the energy storage cabinet fire detector, where:

[0043] The key module is used to send a test signal to the main controller;

[0044] The main controller is used to generate a first addressing signal after receiving the test signal, transmit the first addressing signal to the addressing circuit, receive the addressing feedback signal transmitted by the communication circuit, and send a corresponding indication control signal to the indication module according to the addressing feedback signal;

[0045] The addressing circuit is used to convert the first addressing signal into a second addressing signal and transmit the second addressing signal to the energy storage cabinet fire detector;

[0046] The communication circuit is used to receive the addressing feedback signal transmitted by the energy storage cabinet fire detector and transmit the addressing feedback signal to the main controller;

[0047] The indication module is used to emit corresponding sound and light indication information in response to the indication control signal;

[0048] The power supply module is used to supply power to the main controller, the addressing circuit, the communication circuit, and the indication module.

[0049] During specific implementation, the tester can send a test signal to the main controller by operating the key module. After receiving the test signal, the main controller generates a corresponding first addressing signal and transmits the first addressing signal to the addressing circuit. The addressing circuit converts the first addressing signal into a second addressing signal and transmits the second addressing signal to the address line of the energy storage cabinet fire detector, so that the energy storage cabinet fire detector completes the automatic addressing function test based on the second addressing signal and transmits the addressing feedback signal back to the communication circuit through the corresponding communication protocol. The communication circuit transmits the addressing feedback signal to the main controller, and the main controller sends a corresponding indication control signal to the indication module according to the addressing feedback signal. The indication module emits corresponding sound and light indication information in response to the indication control signal, so that the tester can intuitively determine the test result of the automatic addressing function of the energy storage cabinet fire detector according to the sound and light indication information.

[0050] The device further includes a main control circuit board, and the key module, the main controller, the addressing circuit, the communication circuit, the indication module, and the power supply module are all integrated on the main control circuit board. By integrating the key module, the main controller, the addressing circuit, the communication circuit, the indication module, and the power supply module on the main control circuit board, the integration degree of the device can be improved, the space can be saved, and it is convenient for unified packaging and use.

[0051] Further, as Figures 2 to 6As shown, the main controller uses a STM32H743VIT6 microcontroller and can output a TTL-level addressing signal. As Figure 7 shown, the addressing circuit includes a MAX3232ES E+T type RS232 transceiver chip. The first addressing signal with TTL level output by the main controller is converted into a second addressing signal with RS232 level through the MAX3232ES E+T type RS232 transceiver chip. The addressing circuit transmits the second addressing signal to the energy storage cabinet fire detector by connecting the address line IN / OUT of the energy storage cabinet fire detector, so that the energy storage cabinet fire detector can perform an automatic addressing function test according to the second addressing signal. As Figure 8 shown, the communication circuit includes a TJA1050T / CM,118 type CAN bus transceiver chip and a common mode inductor. The CAN bus transceiver chip is used to realize the transceiver of CAN bus protocol signals, and the common mode inductor plays a role in filtering electromagnetic interference of signals. The indication module includes a test indicator light and a buzzer. The energy storage cabinet fire detector transmits an addressing feedback signal back to the communication circuit according to the CAN bus protocol. The communication circuit transmits the addressing feedback signal to the main controller through the transceiver for determination. If the addressing feedback signal conforms to the content agreed in the communication protocol, the main controller can control the test indicator light to turn green and control the buzzer to emit a continuous sound. If the addressing feedback signal does not conform to the content agreed in the communication protocol, the main controller can control the test indicator light to turn red and control the buzzer to emit an intermittent sound. As Figure 9 shown, the button module includes a switch button SW-PB. By pressing the switch button, the test switch of the main controller can be realized.

[0052] Furthermore, as Figures 10 to 12 shown, the power supply module includes a first power conversion circuit for converting a 24V DC external power supply into a 5V DC power supply for output, an isolation power supply circuit for isolating the 5V DC power supply output by the first power conversion circuit and outputting an isolated 5V DC power supply, and a second power conversion circuit for converting the isolated 5V DC power supply output by the isolation power supply circuit into a 3.3V DC power supply. The first power conversion circuit includes a TPS5430DDA type voltage regulator chip, which can convert a 24V DC external power supply into a 5V DC power supply for output. The isolation power supply circuit includes a B0505S-1WR3 type DC-DC isolation chip, which can realize the isolation conversion of a 5V DC power supply to a 5V DC power supply, playing an effective power isolation protection role. The isolated 5V DC power supply output by it can supply power to the main controller. The second power conversion circuit includes a SPX1117M3-L-3-3 type voltage regulator chip, which can convert a 5V DC power supply into a 3.3V DC power supply.

[0053] Furthermore, as Figure 13As shown, the main controller is connected to a programming serial port, and serial programming of the main controller can be achieved through the programming serial port. As Figure 14 As shown, the main controller is connected to status indicator lights for indicating the working status of the device. Exemplarily, a fault indicator light can be set to indicate the fault condition of the device, a communication indicator light can be set to indicate the communication condition of the device, and an operation indicator light can be set to indicate the operation condition of the device. Each status indicator light respectively uses a light-emitting diode of a corresponding color.

[0054] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
