In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
A conventional transmission valve control device communication system is shown in fig. 1, wherein a converter valve monitoring device 101 and a valve tower monitoring device 102 are both hung on a field communication bus 103, and the field communication bus 103 is connected with a pole control background 106 through a protocol conversion device 104 and a switch 105, so that the networking mode is complex, the device cost is high, the debugging workload is large, and errors are prone to occur.
The transmission valve control equipment communication method provided by the embodiment of the application can be applied to a transmission valve control equipment communication system shown in fig. 2. Transmission valve accuse equipment communication system includes valve accuse equipment 202, switch 204 and utmost point accuse backstage 206.
Among them, the valve control apparatus 202 includes a converter valve monitoring apparatus 2021 and a valve tower monitoring apparatus 2022. One end of the valve tower monitoring equipment 2022 is in communication connection with the converter valve monitoring equipment 2021, and is used for receiving first operation data of the converter valve, which is acquired by the converter valve monitoring equipment 2022; acquiring second operation data of the valve tower in real time; processing and summarizing the first operating data and the second operating data to obtain operating information of the valve control equipment; and uploading the running information of the valve control equipment to a pole control background 206 through the switch 204.
The converter valve monitoring device 2021 is a device for controlling and monitoring an operation state of a converter valve, and specifically, the converter valve monitoring device 202 controls the conduction of a thyristor according to an operation mode of the converter valve, and monitors the operation state of the thyristor, such as loss of return or protective triggering. If the converter valve monitoring device 2021 fails to properly control the thyristors or the number of thyristor operating faults exceeds a limit value, it may cause the converter valves to operate abnormally resulting in direct latch-up. It is understood that the number of the converter valve monitoring devices 2021 in the valve control device 202 may be set according to actual conditions.
The valve tower monitoring device 2022 is a device for monitoring the operation state of the valve tower, and processing, aggregating and transmitting the valve tower operation data and the converter valve operation data, and specifically, the valve tower monitoring device 2022 is originally used for monitoring relevant operation signals of the valve tower, such as water leakage and lightning arrester action signals. Because the signals monitored by the valve tower monitoring equipment 2022 generally do not affect the normal operation of the converter valve, and even if the signals are abnormal, the signals only represent that the converter valve has slight faults, the processing and transmission functions of the operation data are integrated on the valve tower monitoring equipment 2022, so that even if the communication function is damaged, the normal operation and important information acquisition of the converter valve equipment are not affected, and the reliability of the operation of the power system is effectively ensured.
The switch 204 is configured to establish an independent electrical signal channel for the valve control device 202 and the pole control background 206, and transmit operation information of the valve control device.
In particular, switch 204 is a network device for forwarding electrical signals that may provide an exclusive electrical signal path for any two network nodes accessing the switch. The switch 204 is in communication connection with the valve control device 202 and the polar control background 206, respectively, to establish an exclusive electric signal channel between the valve control device 202 and the polar control background 206.

It is to be understood that the data storage system may store data that the polarization backend 206 needs to process. The data storage system may be integrated on the polar control back-end 206, or may be placed on the cloud or other network server. The control background 206 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, the valve tower monitoring device and the polar control background are pre-configured with a communication model file for generating and verifying the operation information of the valve control device.
Specifically, the communication model file is a file created according to all communication data that needs to be transmitted between the valve control device and the polar control background, and the communication model file specifies the types of data transmitted between the valve control device and the polar control background.
Because the communication function with the pole control background is integrated on the valve tower monitoring equipment, communication model files are pre-configured on the valve tower monitoring equipment and the pole control background. The valve tower monitoring equipment determines data to be communicated, which need transmission communication actually, from a plurality of operation data according to the communication model file, collects all screened data to be communicated to generate operation information of the valve control equipment, and transmits the operation information of the valve control equipment to the pole control background. The pole control background verifies the received operation information of the valve control equipment according to the communication model file configured by the pole control background, analyzes the operation information after the verification is successful, determines the operation state of the converter valve, effectively avoids the situation that the operation speed of the system is reduced due to excessive data received by the pole control background, and improves the response speed of the communication system.

It can be understood that the communication bus communication functions correspond to the first communication bus interfaces one to one.
In one embodiment, the first communication bus interface is a CAN interface, the communication bus function arranged on the first main control chip is a CAN communication function, and the valve tower monitoring device and the converter valve monitoring device are in communication connection by adopting a CAN bus.
The protocol stack communication task corresponding to the preset communication protocol is added in the first main control chip after the first main control chip and the polar control background negotiate in advance to determine the communication protocol, so that the first main control chip can be in communication connection with the polar control background through the switch based on the preset communication protocol, and the collected and received running information of the valve control equipment is sent to the polar control background.
In one embodiment, the preset communication protocol is an IEC61850 communication protocol, and the protocol stack communication task is an IEC61850 protocol stack communication task.
