Description

Technical Field

[0001] This utility model relates to the field of energy storage fire protection equipment technology, and in particular to a new energy storage fire station-level control host and its single-chip microcomputer unit. Background Technology

[0002] like Figure 1 As shown, the existing fire station-level control unit mainly includes a monitor, a programmable logic controller (PLC), an uninterruptible power supply (UPS), a kVM switch, indicator lights, buttons, a printer, an industrial computer, and a switch. This fire station-level control unit can receive fire signals and activate automatic fire extinguishing equipment and fire-fighting linkage control equipment for fire suppression. It can also remotely and manually control lower-level fire extinguishing equipment and fire-fighting linkage control equipment via buttons.

[0003] However, existing fire station-level mainframes can typically link 20-40 fire-fighting devices, while energy storage power stations generally require over 100. Therefore, existing fire station-level mainframes are limited by the cost and expansion capacity of PLCs, making it difficult to meet the demands of such a large system. Furthermore, each additional linked device requires corresponding buttons, indicator lights, and PLC I / O interfaces, making it difficult to add more components within a limited space. The wiring between the industrial computer, switch, PLC, buttons, and indicator lights is complex, making maintenance difficult in emergencies. In addition, both the PLC and industrial computer participate in logic control calculations, wasting computing power and reducing operational efficiency. If the PLC fails, all buttons, indicator lights, UPS, etc., connected to the PLC will go offline. Utility Model Content

This concentrates the logic calculation function on the industrial controller, resulting in a simpler structure and reduced production, maintenance costs, and maintenance difficulty. When the microcontroller on the microcontroller unit is damaged, only the microcontroller needs to be replaced. Moreover, multiple microcontroller units in this invention are linked together via a first RS485 interface and a second RS485 interface.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Reference Figure 2 The present invention proposes a new energy storage fire station level control host, which includes: an industrial control computer 1, a switch 3, a UPS power supply 2 and multiple single-chip microcomputer units 4;

[0026] Each microcontroller unit 4 includes a microcontroller, an indicator light, an illuminated button, a control button, an alarm, a UPS power supply 2, a CAN interface, an Ethernet port, a first RS485 interface, and a second RS485 interface. The first RS485 interface and the second RS485 interface can transmit and receive simultaneously and independently. The indicator light, the illuminated button, the control button, the alarm, the CAN interface, the Ethernet port, the CAN interface, the first RS485 interface, and the second RS485 interface are all electrically connected to the microcontroller.

[0027] Multiple microcontroller units 4 are arranged sequentially, and the second RS485 interface of each microcontroller unit 4 is electrically connected to the first RS485 interface of the adjacent microcontroller unit 4, so that the multiple microcontroller units 4 form a chain connection.

[0028] The first RS485 interface of the microcontroller unit 4 located at the head of the chain connection is electrically connected to the UPS power supply 2, and the Ethernet port of the microcontroller unit 4 located at the head of the chain connection is electrically connected to the switch 3, and the switch 3 is electrically connected to the industrial control computer 1.

[0029] In practice, the industrial control computer 1 is used to obtain the fire situation reported by the fire linkage control device through the microcontroller unit 4, and to control the activation of the suppression host and the corresponding fire linkage control device to carry out fire extinguishing according to the fire situation through the microcontroller unit 4.

[0030] This invention uses a single-chip microcomputer unit 4 to replace the original PLC, integrating some functions of the original PLC and the functions of indicator lights. This concentrates the logic calculation function on the industrial controller, making the structure simpler and reducing production and maintenance costs and difficulties. When the single-chip microcomputer on the single-chip microcomputer unit 4 is damaged, only the single-chip microcomputer needs to be replaced. Moreover, the multiple single-chip microcomputer units 4 in this invention are connected in a chain through the first RS485 interface and the second RS485 interface. The single-chip microcomputer unit 4 at the head of the chain acts as the single-chip microcomputer master, and all the other single-chip microcomputer units 4 act as single-chip microcomputer slaves. Each single-chip microcomputer slave or single-chip microcomputer master can connect to 40 fire linkage control devices, providing good scalability. In addition, when the single-chip microcomputer master fails, the next adjacent single-chip microcomputer slave will automatically become the single-chip microcomputer master. When a single-chip microcomputer slave fails, the data reading of this slave will be skipped, without affecting other parts.

[0031] In one specific embodiment, switch 3 is a PoE switch 3, and the Ethernet port is a PoE network port. Therefore, the microcontroller unit 4 in this embodiment can be powered while communicating via the network cable, without the need for a separate power cord.

[0032] Of course, when the number of connections is too large, in order to avoid overload, switch 3 is a regular switch 3. Switch 3 is connected to the microcontroller host in a conventional power supply mode, and the microcontroller host then supplies power to the slave device via PoE.

[0033] In this embodiment, the control buttons include a manual / automatic button, a fault reset button, and an alarm reset button.

[0034] With this configuration, this embodiment can remotely and manually initiate fire suppression, fault reset, and alarm reset.

[0035] In a further embodiment, a spare button is also included.

[0036] In this embodiment, the indicator lights include mains power indicator lights, backup power indicator lights, and fault indicator lights, so as to intuitively determine the power supply and whether there is a fault.

[0037] In a further embodiment, the indicator light also includes a backup indicator light.

[0038] In this embodiment, the microcontroller includes a power module, a relay module, an MCU, a real-time clock module (RTC), a storage module, a watchdog module, and a multiplexing module;

The relay module is electrically connected to the alarm. The multiplexing module is electrically connected to the illuminated button. The MCU is electrically connected to the indicator light, control button, CAN interface, Ethernet port, first RS485 interface, and second RS485 interface.

[0040] Specifically, the power supply module includes a mains electronic module and a backup electronic module. The mains electronic module includes a 24V to 5V conversion circuit and a 5V to 3.3V conversion circuit. The 24V to 5V conversion circuit supplies power to indicator lights, illuminated buttons, and relays, while the 5V to 3.3V conversion circuit supplies power to the MCU, real-time clock module (RTC), storage module, watchdog module, multiplexing module, CAN interface, Ethernet port, first RS485 interface, and second RS485 interface.

[0041] The backup electronic module is a battery.

[0042] Secondly, such as Figure 3As shown, this utility model also proposes a microcontroller unit 4 for a new energy storage fire station-level control host, including: a microcontroller, indicator lights, illuminated buttons, control buttons, an alarm, a CAN interface, an Ethernet port, a first RS485 interface, and a second RS485 interface. The first RS485 interface and the second RS485 interface can simultaneously and independently transmit and receive data. The indicator lights, illuminated buttons, control buttons, alarm, CAN interface, Ethernet port, CAN interface, first RS485 interface, and second RS485 interface are electrically connected to the microcontroller.

[0043] In practice, multiple microcontroller units 4 are arranged sequentially, and the second RS485 interface of each microcontroller unit 4 is electrically connected to the first RS485 interface of the adjacent microcontroller unit 4, so that the multiple microcontroller units 4 form a chain connection.

[0044] The first RS485 interface of the microcontroller unit 4 at the head of the chain connection is electrically connected to the UPS power supply 2, and the Ethernet port of the microcontroller unit 4 at the head of the chain connection is electrically connected to the switch 3. The switch 3 is electrically connected to the industrial control computer 1. Therefore, the microcontroller unit 4 at the head of the chain connection acts as the microcontroller master, and all other microcontroller units 4 act as microcontroller slaves. Each microcontroller slave or master can connect to 40 fire-fighting linkage control devices, providing good scalability. In addition, when the microcontroller master fails, the next adjacent microcontroller slave will automatically become the master. When a microcontroller slave fails, the data reading of that slave will be skipped, without affecting other parts. Moreover, the microcontroller unit 4 integrates the original indicator light function and replaces the original PLC, concentrating the logic calculation function on the industrial control computer, simplifying the structure and reducing production costs, maintenance costs, and maintenance difficulty. When the microcontroller on the microcontroller unit 4 is damaged, only the microcontroller needs to be replaced.

[0045] In this embodiment, the Ethernet port is a PoE port. Therefore, the microcontroller unit 4 in this embodiment can be powered while communicating via the network cable, without the need for a separate power cord.
