Existing communication devices usually only have one communication method. The communication method of the product is fixed and single, which makes it difficult to be compatible with different types of energy storage fire detection systems. In addition, there are many redundant functions and a high failure rate. Utility Model Content

At this time, the control alarm module sends an alarm message to prompt the supervisor to conduct a fire condition check in time. Since the communication interface module includes at least two interface modes, the CAN bus interface and the RS485 interface, bidirectional conversion is expanded, so that the communication mode can adapt to the communication requirements of different products and has better compatibility.

[0018] In some exemplary embodiments, the alarm module includes a buzzer.

[0019] The above technical solution is implemented, and an alarm prompt is realized by a buzzer sending out a buzzing sound.

[0020] In some exemplary embodiments, the light indication module includes a power indicator light, a signal sending indicator light, and a signal receiving indicator light.

[0021] To implement the above technical solution, different states are indicated by different indicator lights.

[0022] In some exemplary embodiments, the CAN bus interface and the RS485 interface both use Phoenix terminal interfaces.

[0023] By implementing the above technical solution, the wiring method is more convenient and safer.

[0024] In some exemplary embodiments, the device further comprises a PCB board, wherein four corners of the PCB board are provided with oval-shaped mounting holes, and a setting direction of one of the mounting holes is perpendicular to a setting direction of the other mounting holes.

[0025] To implement the above technical solution, by setting the mounting holes in different directions, the PCB board can only be installed in a certain direction to prevent reverse connection.

[0026] In some exemplary embodiments, the device is encapsulated in a sealed housing, connecting ears are provided on both sides of the sealed housing, connecting holes are opened on the connecting ears, and sound transmission holes are provided on the sealed housing corresponding to the alarm module.

[0027] To implement the above technical solution, the device can be conveniently fixed on the installation station through the connecting ears and the connecting holes, and the setting of the sound transmission hole can facilitate the transmission of the alarm sound.

[0037] Specifically, the main control MCU module 10 is the main computing processing unit, and an optoelectronic isolator 11 is also provided between the communication interface module 20 and the main control MCU module 10. The optoelectronic isolator 11 is also called an optoelectronic coupler, which can transmit electrical signals using light as a medium. The electrical-optical-electrical signal conversion process can have a good isolation effect on the input and output electrical signals, thereby providing anti-interference capability. The optoelectronic isolator 11 can provide better anti-static and surge capabilities, so that the device can work stably even in harsh environments.

[0038] Among them, both the CAN bus interface 21 and the RS485 interface 22 use Phoenix terminal interfaces, making the wiring method more convenient and safe. In this embodiment, 24V DC power supply is used, and the CAN bus interface 21 and the RS485 interface 22 can both be used as power supply terminals to facilitate power supply.

[0039] In this embodiment, the alarm module 40 includes a buzzer, and the alarm prompt is implemented by the buzzer emitting a buzzing sound. In some embodiments, the alarm module 40 can also use a speaker to provide an alarm prompt by playing voice information.

For example, the power indicator light 61 is green, the signal generating indicator light is yellow, the signal receiving indicator light 63 is red, etc. Different statuses are indicated by different indicator lights.

[0041] At the same time, the main control MCU module 10 is also connected to a reset button 12, which is used to control the cancellation of the alarm state. The reset button 12 allows supervisors to cancel the alarm after eliminating the fire risk or in case of a false alarm.

[0042] The bidirectional conversion device for the energy storage fire detection system of the utility model also includes a PCB board 80, which is used to carry functional modules such as a main control MCU module 10, a communication interface module 20, a storage module 30, an alarm module 40, a watchdog circuit module 50, a light indication module 60, and a reset button 12, wherein a CAN bus interface 21 and an RS485 interface 22 are respectively arranged on both sides of the PCB board 80; four corners of the PCB board 80 are provided with waist-shaped mounting holes 81, and the setting direction of one of the mounting holes 81 is perpendicular to the setting direction of the other mounting holes 81, and through the mounting holes 81 with different setting directions, the PCB board 80 can only be installed in a certain direction to prevent reverse connection.

[0044] When the energy storage fire detection system is in operation, it communicates with external sensors or other external devices through the communication interface module 20, and the received data is stored through the storage module 30. The main control MCU module 10 compares the received real-time detection data with the preset parameter threshold value stored in the storage module 30. When the real-time detection data exceeds the preset parameter threshold value, it indicates that a fire may occur. At this time, the control alarm module 40 sends an alarm message to prompt the supervisor to conduct a fire condition check in time. Since the communication interface module 20 includes at least two interface modes, the CAN bus interface 21 and the RS485 interface 22, bidirectional conversion is expanded, so that the communication mode can be adapted to the communication requirements of different products and the compatibility is better. At the same time, the watchdog circuit module 50 performs program detection and correction regularly to ensure stable operation of the device without downtime, provide protection for the continuous operation of the device, reduce the failure rate, and display the working status of the device in real time through the light indication module 60, which can better facilitate the supervision of the device.
