The invention provides a machine room dynamic ring monitoring device which comprises:

as shown in fig. 1-3, comprising: a monitoring device on which a monitoring master station service is deployed, the monitoring device comprising: the system comprises a monitoring main board, a back board, a plurality of expansion boards, a power supply module, a display module and a display module; the monitoring main board is respectively connected with the power module, the display module and the back board, the back board is connected with the expansion board, and the expansion board is used for connecting a service terminal needing to be monitored.

The device is mainly used for monitoring the power environment of a communication machine room in an electric power system, and monitoring characteristic objects generally comprise switch analog quantity, digital quantity input and output and current quantity. The hardware structure diagram of the implementation method of the integrated monitoring device of the electric power communication machine room is shown in fig. 1, and the integrated monitoring device mainly comprises a monitoring mainboard, a backboard, a power supply module, a PCIE expansion board and a display unit (touch screen), wherein the working flow principle of the integrated monitoring device is shown in fig. 2, and a complete system loop is formed by the monitoring mainboard, the backboard and the PCIE expansion board. When the system works normally, the monitoring characteristic quantity is transmitted between the monitoring main station and the remote service terminal through the system loop. In fig. 1, when any expansion board in a PCIE expansion board fails, normal operation of the monitoring apparatus is not affected, and the monitoring apparatus system reports status information to the master station service in real time and performs self-repair processing operation. Fig. 3 is a schematic diagram of a hardware structure of a PCIE expansion board, and a suitable PCIE switch chip may be selected according to requirements to determine functions and performance of the expansion board.

During work, the PCIE expansion board type is selected according to requirements, the PCIE expansion boards of a certain type and quantity are adaptively designated after verification, and the PCIE expansion boards are connected with the dynamic loop monitoring front-end processor through the Ethernet interface. The monitoring device supports 7 PCIE expansion slot interfaces and 6 gigabit Ethernet at most, and each expansion slot can be inserted with a service expansion board at will. For serial port services, a single expansion board supports 8 paths, for three-remote services, the single expansion board supports 8 paths of remote measurement, 8 paths of remote signaling and 1 path of remote control, and for service requirements of entrance guard, video, infrared and the like, the monitoring device can be adapted to the PCIE expansion port, and is flexible and reliable.

The monitoring master station service deployed on the device issues a control command, signals are transmitted to the monitoring mainboard of the invention through a communication network, and after information analysis and protocol conversion, the signals are transmitted to a specified function expansion board through PCIE bus interface conversion.

For the non-intelligent remote service terminal, the dynamic ring monitoring front-end processor or the PCIE expansion board directly converts the analog signal of the sensor of the remote service terminal into a digital signal and then directly transmits the digital signal to the monitoring main board; for an intelligent remote service terminal, a mobile ring monitoring front-end processor or a PCIE expansion board needs to perform information interaction with the mobile ring monitoring front-end processor or the PCIE expansion board according to a relevant protocol, and forward the information to a monitoring main board after acquiring the information.

The monitoring main board analyzes the command and then forwards the command to a designated PCIE expansion board, after receiving the acquired signal voltage analog quantity returned by the corresponding PCIE expansion board, the monitoring main board performs protocol conversion and data encapsulation, and sends information AA01010100211255 to the main board; in turn represent the following: "AA" indicates a data start, "01" indicates a direction from the remote service terminal to the monitoring master station, "0101" indicates a 1 st path voltage analog acquisition channel of the first PCIE expansion slot, "0021" indicates a voltage analog acquisition value, "12" indicates a data check bit, and "55" indicates a data end bit, and if abnormal information exists, the abnormal information is uploaded to the monitoring master station in real time for service.

In order to verify the actual application effect of the implementation method of the integrated monitoring device of the electric power communication machine room, a certain power communication machine room of the transformer substation is selected for field experiments. In the testing process, the monitored object is changed artificially, meanwhile, the PCIE expansion board is adjusted to be matched with the PCIE expansion board in time by the monitoring device, various power communication machine room characteristic information can be effectively monitored by applying the implementation method of the integrated monitoring device of the power communication machine room, and abnormal information can be completely uploaded to the monitoring master station in real time and alarm information is sent out.
