Problems solved by technology
[0003] The invention mainly solves the problem that the fault point cannot be remotely located when the remote control of the EMS main station fails, and the staff needs to go to the scene to check. After the remote control operation fails, it is a function pre-test method of the data communication gateway machine to assist in detecting whether the remote control failure is caused by the abnormality of the gateway machine to the measurement and control device itself

Embodiment
[0025] In this embodiment, a data communication gateway machine function pre-test system, such as figure 1 As shown, including gateway machine 1, EMS master station 2, measurement and control device 3, operation and maintenance master station 4 and operation and maintenance substation 5, the gateway machine communicates with the EMS master station through IEC104, communicates with the measurement and control device through IEC61850MMS, and accepts the EMS master station The issued remote control command is sent to the measurement and control device, and then the slave device returns the result to the master station. The operation and maintenance master station is deployed at the main station of the operation and maintenance management and control system, and the operation and maintenance sub-station is deployed at the substation end. The operation and maintenance master station and the operation and maintenance sub-station communicate through GSP; There are IEC104 channel and ...

The invention relates to a function pre-test method and system for a data communication gateway machine. The method comprises the following steps: initiating a remote control pre-test command; enabling the operation and maintenance substation to receive the remote control pretest command, and if the command can be executed, forwarding the command to the gateway machine; otherwise, sending a function pretest failure alarm to the operation and maintenance master station and recording a preset serialization report; enabling the gateway machine to receive the remote control pre-test command, and if the gateway machine is not abnormal, forwarding the remote control pre-test command to the measurement and control device; otherwise, enabling the gateway machine to send a remote control command failure state message to the operation and maintenance substation; enabling the measurement and control device to receive the remote control pre-test command, and if the measurement and control device is not abnormal, returning a remote control command anti-correction message; and otherwise, enabling the measurement and control device to send a state message that the remote control command fails to work to the gateway machine. The system comprises a gateway machine, an EMS main station, a measurement and control device, an operation and maintenance main station and an operation and maintenance substation. The method and the system have the advantages that: the remote control function test is realized on the premise of not changing the working state of the measurement and control device; and it is verified whether remote control in the station has a problem or not, and assisting in detecting remote control failure reasons.
Description
technical field [0001] The invention relates to the field of smart grids, in particular to a function pretest method and system for a data communication gateway. Background technique [0002] At present, the data communication gateway machine is connected to the EMS master station through the dispatching data network through the IEC104 communication protocol, transmits the data to the EMS master station, and accepts the remote control information issued by the EMS master station. Due to the complex link between the EMS master station and the gateway, when the remote control of the EMS master station fails, it is impossible to clearly know whether there is a problem between the gateway in the station and the measurement and control device, causing the remote control to fail, or the communication link. A failure caused by a problem. In addition, if the failure is caused by reasons within the station, since 104 cannot transmit the specific reason for the failure, the master st...
