Test method based on IEC60870-5-101 protocol of telecontrol device

Abstract

The invention provides a test method based on an IEC60870-5-101 protocol of a telecontrol device; the test method comprises the following steps: carrying out initialization configuration on a system; establishing a 101 protocol unbalanced transmission channel; reading a message; and parsing the message. According to the test method based on the IEC60870-5-101 protocol of the telecontrol device provided by the invention, a site test can be carried out on the telecontrol device; and through analyzing the message formed by test results, the reason for communication failure and the current running status of the device can be obtained; and thus, the monitoring on interchange and interoperation among communication devices using the IEC60870-5-101 protocol is realized, and the purpose of improving the working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of information communication of a power grid automation system, and more specifically, relates to a telecontrol device-based IEC60870-5-101 protocol testing method. Background technique [0002] At present, there are a large number of foreign imported telecontrol equipment used in the power system, and with the in-depth development of smart grid construction, there are more and more interconnection requirements between various telecontrol equipment systems, so the power system, automatic control The requirements of the system and the like are also becoming higher and higher. The basis for the interconnection of various telecontrol equipment and device systems is the communication protocol or communication protocol. Therefore, it is very important for each manufacturer to be familiar with the transmission rules of the protocol, and to transmit messages according to the transmission rules, and it is also a mus...

Problems solved by technology

However, due to the inconsistency of the telecontrol equipment of the master station (control station) and the slave station (controlled station), various problems often occur in the communication between the master station and the slave station. Therefore, the staff must detect in real time to Ensure the normal communication and operation of the equipment. If the equipment is not detected in time, it will cause abnormal communication and affect the interconnection of various telecontrol equipment
