Description

TECHNICAL FIELD

[0001] The application relates to a gateway device IEC60870 protocol uplink configuration method and device, and belongs to the technical field of sensor information points in intelligent transformer substation buildings. BACKGROUND

[0002] IEC60870 standard, as the communication standard for power system monitoring and control formulated by the International Electrotechnical Commission (IEC), occupies a core position in the field of electric power; the standard can ensure that information can be accurately and efficiently transmitted between various devices in the power system, realizing real-time monitoring and effective control of the power system.

[0003] In the IEC60870 standard system, IEC60870-5 further specifies the general requirements of power system remote devices and systems; it provides more detailed specifications and guidance for remote communication of power systems, ensuring accurate transmission and reliable reception of remote information; and IEC60870-5-104 and IEC60870-5-101, as important components of the standard system, play a key role in monitoring and control of power systems (especially transformer substation buildings).

[0004] IEC60870-5-101 is generally used for serial communication, such as RS-232 or RS-485 serial interface, and plays an important role in remote control and data acquisition of power systems; it is suitable for traditional power system environment, especially in some scenes where communication speed is not high but stability is required. IEC60870-5-104 is the network version of IEC60870-5-101, based on TCP / IP network communication, can use Ethernet, and is suitable for network communication environment in modern power systems; it can realize long-distance data transmission and provide strong support for remote control and monitoring of large power systems.

[0005] IEC60870-5-101 and IEC60870-5-104 have the same data type in the power system, and for remote signaling data, it is generally single-point or double-point type data; for remote measurement data, there are three types of data, normalized value, scaled value or short floating point type value. Since the data types of the two are the same and only the communication methods are different, they can complement each other in different application scenarios and jointly provide protection for the stable operation of the power system.

[0006] For IEC60870-5-101 and IEC60870-5-104, because they are respectively applicable to serial communication and network communication, different parameter settings and technical requirements need to be considered in the configuration process. For example, the configuration of IEC60870-5-101 needs to pay attention to the settings of serial port parameters such as baud rate, data bits, stop bits and check bits, while the configuration of IEC60870-5-104 involves network parameter settings such as IP address, subnet mask, gateway address and port number. In the system design stage, engineers need to understand the configuration requirements of the two protocols respectively, and make reasonable design according to the actual application scene. In the debugging process, if there is a problem, the configuration of the two protocols needs to be checked respectively, which increases the complexity and time cost of debugging. In the maintenance stage, maintenance personnel also need to be familiar with two different configuration methods in order to handle possible faults in time, which puts higher requirements on the technical level of maintenance personnel.
