Illustratively, the cabinet controller is further configured to set a communication address for each monitoring unit for internal communication of the cabinet monitoring system.
In one embodiment, the cabinet controller may support access to 32 different address monitoring units. Wherein, address 01-address 10 is set as power supply monitoring unit address, address 11-address 15 is set as communication monitoring unit address, address 16 is set as cabinet durability monitoring unit address, address 17 is set as lock monitoring unit address, address 18 is set as smoke monitoring unit address, address 19 is set as cabinet integrity monitoring unit address, address 20 is set as pressure monitoring unit address, address 21 is set as monitoring module function display table, address 22-address 23 is set as temperature monitoring unit address, address 24 is set as fan address, address 25-address 32 is set as insulation monitoring address.
In another embodiment, the cabinet controller address is a master address, the monitoring units address is slave addresses, and the communication address of each monitoring unit in the cabinet monitoring system is a combination of the master address and the slave addresses. In the process of setting the address of the monitoring unit, the address of the monitoring unit can be automatically coded based on the sequence of the fixed address numerical values. When the system needs to add a new monitoring unit, an unoccupied address is allocated to the newly-set monitoring unit.
In another embodiment, the cabinet controller is further configured to send the status signal to the display screen based on the Modbus protocol.
In the cabinet monitoring system, the cabinet controller communicates with the display screen through a Modbus protocol, and the cabinet controller sends the status signal to the display screen through the Modbus protocol.
In one embodiment, the display screen is connected with the cabinet controller through an RS485 interface, and data transmission is performed through a Modbus protocol. Specifically, the cabinet controller receives the status signal sent by the monitoring module and sends the status signal to the display screen through the Modbus protocol. After the display screen receives the state signal, the signal is sorted, analyzed and converted through the internal integrated computing unit, and a monitoring result is obtained and displayed. The user can obtain the monitoring result of the cabinet monitoring system in real time on the display interface.
Optionally, an RS485 interface is arranged between the monitoring unit and the cabinet controller, and data transmission is performed through a Modbus protocol. Specifically, after acquiring the state signal, the monitoring unit sends the state signal to the cabinet controller through a Modbus protocol.
Optionally, after the display screen obtains the monitoring result, the monitoring result is sent to a remote control center through a Modbus TCP protocol, so that the user can perform remote monitoring and control.
The cabinet controller in this embodiment is further configured to send the status signal to the display screen based on the Modbus protocol. The complexity of the internal interactive messages of the cabinet monitoring system is reduced through the Modbus protocol, various electrical interfaces can be supported, and the usability of the cabinet monitoring system is improved. Meanwhile, because the message interaction mode of the Modbus protocol is a question-and-answer mode, if a link of message sending or message receiving is lacked, a communication fault is indicated, and therefore the communication state of the cabinet monitoring system can be fed back in time.
In another embodiment, the display screen further comprises a communication unit, wherein: and the communication unit is used for sending the monitoring result to the control center.
Exemplarily, the display screen is also provided with a communication unit, the communication unit is used for sending the monitoring information to the control center, and the user can acquire the state information of each cabinet machine in real time in the central control room without acquiring the state information on site, so that remote monitoring and control are realized.
