Background
At present, a data communication network is accessed to an EMS master station through a scheduling data network by an IEC104 communication protocol, data is transmitted to the EMS master station, and remote control information sent by the EMS master station is received. Because a complex link is experienced between the EMS master station and the network shutdown machine, when the EMS master station fails in remote control, it cannot be clearly known whether a problem occurs between the internal network of the station shutdown machine and the measurement and control device, which causes the remote control failure, or the failure caused by the problem of the communication link. In addition, if the failure is caused by the reason in the station, the main station cannot know the specific reason of the failure because 104 cannot transmit the specific reason of the failure, and people must be dispatched to the site to search and analyze the phenomena one by one.

s4: the measurement and control device receives the remote control pre-test command, and if the measurement and control device is not abnormal, a remote control command anti-correction message is returned; otherwise, the measurement and control device sends a state message of failure of the remote control command to the gateway machine, and the gateway machine forwards the state message to the operation and maintenance substation.
The method can ensure that whether remote control in the station has problems or not through a 104 channel between the operation and maintenance substation and the network shutdown machine under the condition that the network in the station is shut down to a measurement and control link is not changed, and assists in detecting whether remote control failure is caused by the fact that the network shutdown machine is abnormal to the measurement and control device after the EMS system fails to execute remote control operation.
As a preferred scheme of the above scheme, the operation and maintenance master station issues a remote control cancellation command after receiving the remote control command reverse correction message, and the measurement and control device returns a remote control cancellation confirmation message after receiving the remote control cancellation command. By executing the remote control cancelling command, the remote control function pre-test is realized on the premise of maintaining the measurement and control device.

And operation and maintenance personnel can conveniently find and maintain specific reasons of failure.
As a preferred scheme of the above scheme, the operation and maintenance substation acquires a remote control message record file and a log file record of the gateway machine through an MMS channel.
As a preferable scheme of the above scheme, the remote control pre-test command is initiated by one of the operation and maintenance master station and the operation and maintenance substation.
Correspondingly, the invention also provides a system for pre-testing the function of the data communication network machine, which is used for the method for pre-testing the function of the data communication network machine.
In the whole process of remote control pre-test, the sub-station records the execution process of all commands to form a serialized report, and when the pre-test fails, the remote control message record file is analyzed to obtain the failure reason from the remote control message record file and fill the failure reason into the serialized record report. The sub-stations which succeed in pre-test or fail in pre-test send alarm information to the main station, and the main station can inquire the serialized record report of the sub-station remote control pre-test according to the alarm.
As a preferable scheme of the above scheme, an MMS channel and an IE104 channel are established between the operation and maintenance substation and the gateway machine. The IE104 channel is used for function pre-test and issuing remote control commands, and the MMS channel is used for acquiring corresponding files in the gateway.
As a preferred scheme of the above scheme, MMS channels are established between the operation and maintenance substation and the measurement and control device, and between the gateway machine and the measurement and control device.
