[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1 and Figure 2 As shown, a fire equipment power status monitor with a replaceable circuit board includes a pin, a slot, a plastic part, a communication board 9, and a circuit board 16. The slot is installed on the communication board 9, and the pin is installed on the circuit board 16. The pin and the slot are connected. At the same time, the communication board 9 is fixed to the circuit board 16 through the plastic part, or the pin passes through the plastic part and is connected and fixed to the slot.

[0028] The monitor also includes a CAN bus circuit, a dual-bus communication circuit, an RS485 communication circuit, a digital input circuit, and a relay output circuit. The CAN bus circuit, RS485 communication circuit, digital input circuit, and relay output circuit are all arranged on the communication board 9, and the dual-bus communication circuit is arranged on the loop board 16.

[0029] Both the communication board 9 and the circuit board 16 include communication interfaces. The card pin is communicatively connected to the communication interface of the circuit board 16, and the card slot is communicatively connected to the communication interface of the communication board 9.

[0030] The monitor also includes a light keypad 3, which is connected to the communication board 9.

[0031] The monitor also includes an operation panel 11, which is communicatively connected to the button panel 3.

[0032] The control panel 11 includes buttons and indicator lights.

[0033] In this embodiment, there are three main circuit boards: one is the indicator light board 3, used to control indicator lights and buttons; another is the communication board 9, used to control communication, switch inputs, and relay outputs. All field wiring is done on the main control board, which has wiring markings for easy on-site connection. The circuit board 16 is used to connect to a two-wire communication instrument.

[0034] The conventional circuit board 16 is distributed on the communication board 9 via components, while different communication products require separate communication boards 9. Now, the circuit board 16 is made into a small, independent board and fixed in place using pins and plastic parts. The pins provide support and power for communication, while the plastic parts provide fixation and support. The pins are on the circuit board 16, and the communication board 9 has corresponding pin slots. There are also two round holes at opposite corners of the circuit board 16 and at corresponding positions on the communication board 9 for mounting and fixing the plastic parts. By ensuring that the dimensions of the circuit board 16 and the pin and plastic part hole positions are consistent across different products, and that the communication pins are identical, it can be inserted and used. If one circuit is damaged in the field, it will not affect other circuits; only the corresponding circuit board 16 needs to be replaced. The corresponding communication interface on the circuit board 16 is connected to the communication interface on the communication board 9 via metal pins that connect to the pin slots on the communication board 9. This pin connection allows for close proximity and strong anti-interference capability. The circuit board 16 is mounted in the middle of the communication board 9. The plastic component simply needs to be snapped onto the communication board, and then the circuit board is connected according to the pin slots. The holes in the plastic component are aligned and pressed down, exposing the clips on the top of the plastic component. When it is necessary to increase the maximum number of circuits, simply increase the number of slots on the communication board 9 and the number of holes in the plastic component.

[0035] The indicator light board 3 is installed in the middle of the monitor door panel. It is fixed with screws and grounded. It is powered by the communication board 9. Communication and power supply are connected to the indicator light board 3 through a ribbon cable. The indicator light board 3 provides power to the indicator light board 3. Communication is transferred from the indicator light board 3 to the Android screen 4. The Android screen 4 displays and receives instrument information and controls it.

[0036] The external wiring on communication board 9 consists of multiple terminals, including one CAN bus circuit connecting to regional extension units (directly distributed on communication board 9), up to two dual-bus communication loop circuits (via two loop boards 16), two RS485 communication circuits (soldered onto communication board 9), two digital input circuits (directly distributed on communication board 9), and two relay output circuits (directly distributed on communication board 9). Different loop boards 16 are mounted on top of communication board 9 to meet different product requirements and facilitate production personnel in preparing inventory. The dual-bus loop points are connected to the loop boards via pin slots for power supply and communication.

[0037] The monitor also includes circular holes, which are mounted on the communication board 9 and the circuit board 16, with both ends of the plastic component mounted on these holes. The monitor also includes reinforcing ribs, which are mounted on the plastic component and are spiral-shaped. The plastic component includes clips.

[0038] In this embodiment, the circuit board 16 is installed in the middle of the communication board 9 and is fixed by pins and plastic parts. The pins provide support and facilitate communication and power supply, while the plastic parts provide fixation and support. The pins are on the circuit board 16, and the communication board 9 has corresponding pin slots. There are also two round holes at opposite corners of the circuit board 16 and at corresponding positions on the communication board 9 for mounting and fixing the plastic parts. When the pins pass through the plastic parts, the plastic parts provide protection, ensuring the safe transmission of data.

[0039] The monitor also includes a circuit board housing 17, which is mounted on the circuit board 16.

[0040] In this embodiment, a circuit board housing 17 is installed outside the circuit board 16. The housing is metal, which increases the protection of the circuit board. The wiring is done on the communication board 9 to prevent the wiring personnel from accidentally touching it and to prevent metal debris from falling in during the installation process and causing damage to the circuit board. The wiring part is not covered by the circuit board housing 17.

[0041] Furthermore, the internal circuit board 16 of the controller can be configured with the number of circuits selected according to the product, saving costs; different circuit boards can also be installed based on different product protocol types, facilitating production and inventory preparation; when designing products with different protocols or changing the circuit hardware design, the circuit board 16 can be directly replaced, simplifying product design; it can share communication boards with other fire protection products, requiring only the circuit board 16 to be replaced, reducing product design complexity; when a circuit is damaged in the field, only the damaged circuit can be replaced, making replacement convenient. Simultaneously, the same circuit board 16 can be used not only in monitors but also in extension units and other products.

[0042] Two RS485 communication circuits are soldered onto communication board 9, which can meet some field data forwarding needs, and can also forward data through the network port of an Android screen, making it convenient to meet different field requirements.

[0043] One CAN communication circuit is used to extend the distance and capacity for connecting regional extension units. Simultaneously, this circuit board 16 is also used for regional extension unit circuitry, with the same mounting method and function as the monitor, facilitating the preparation of regional extension units to meet different production needs.

[0044] The monitor is connected to a voltage sensor, a current sensor, or a voltage / current sensor. It also includes a miniature printer 1, an Android screen 4, a switching power supply 5, a mounting bracket 6, a grounding terminal 7, a miniature circuit breaker 8, a lead-acid battery 10, a nameplate 12, an external plug 13, a wiring diagram 15, and connecting cables, etc.

[0045] The Android screen 4 is installed on the top of the cabinet door panel. Power input control includes main power input, switching power supply, backup power input, and circuit breaker. The main power input is an external AC220V power supply, and the backup power input is a lead-acid battery, both installed in the lower part of the cabinet. The communication board 9 is installed in the middle of the cabinet, powered by the power input control. The operation panel 11 is installed in the middle of the cabinet door panel. A cover plate 17 is installed above the power input control and communication board 9.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
