Problems solved by technology
[0003] Existing various bus interfaces use dedicated physical interfaces for the bus, and the design of the inspection device needs to be designed for physical connections for different interfaces. If one type of inspection device is designed for each interface, resources and operation The reusability of the detection device is poor, the practicability is not strong, and the recognition rate is low

Embodiment Construction
[0022] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.
[0023] Such as figure 1 As shown, the substation live real-time operation inspection device compatibility interface adaptation equipment of the present invention is used to connect sensors of different interface types, including power supply unit, CPLD, output address selector, data selector, power line, ground line, S1 signal line, S2 signal line, S3 signal line and S4 signal line. In this embodiment, RS485 interface, (RS232 interface) serial port, USB interface, and Ethernet interface can be compatible and adapted.
[0024] The power line and the ground line supply power to the sensor. The power supply voltage of the front-end detection sensor is divided into three levels of power supply requirements: 3.3V, 5V, and 1...

The invention relates to a compatibility interface adaptation device and method for a live real-time operation inspection device of a substation, which is used for connecting sensors of different interface types, including CPLD, output address selector, data selector, power line, ground line, and S1 signal line , S2 signal line, S3 signal line and S4 signal line; the power supply line and the ground line supply power to the sensor, and the handshake protocol identification between the interfaces is realized through the CPLD, which is used to distinguish the power supply requirements of the interface type and the sensor, thereby passing The output address selector can select the output of the digital signal to realize the interface adaptation of the handshake signal. Through the present invention, inspection personnel can choose different sensors according to the requirements of the inspection task, regardless of the interface form of the sensor, the compatibility interface design and the expandable wireless interface can be directly plugged and unplugged.
Description
technical field [0001] The present invention relates to the field of electric power, and more specifically, relates to a compatibility interface adaptation device and method for live real-time operation inspection devices of substations. Background technique [0002] Electric power is the basic industry of the national economy, and electric power equipment is the lifeline of electric power production and operation. As social and economic development requires the construction of a strong power grid, ensuring the safe and stable operation of the power system is an extremely important part of ensuring national strategic energy security. However, with the continuous development of the power grid, the number of substations is increasing day by day, the number of transformers is increasing, and the safety pressure on the operation of substation equipment is gradually increasing. Companies use advanced information technology to vigorously study the monitoring technology for the saf...
