Intelligent interface switching module

Abstract

The invention relates to an intelligent interface switching module. The module comprises a CPU which is connected with two 232 / 485 communication ports, a path of BCD code input and two paths of analog quantity outputs; and through the 232 / 485 input, a signal is then converted into corresponding analog quantity output , or through the BCD code input, the signal is converted into corresponding analog quantity / communication port output . The intelligent interface switching module is equipped with two 232 / 485 communication ports, a BCD code input, and two analog quantity outputs, a signal can be converted into corresponding analog quantity output through the 232 / 485 input, and can also be converted into corresponding analog quantity / communication port output through the BCD code input, so that the problem of interface information communication between existing products in an electric power system can be solved.

Description

technical field [0001] The invention relates to an adapter module, in particular to a gear adapter module. Background technique [0002] The gear position transmitter is an important product for obtaining the gear position information of the tap changer. The basic working principle is to obtain the gear position information from the decomposition switch control box through the 19-core aviation plug, and then use RS232, RS485, BCD code, 4-20ma , 0-5V choose one of the transmission methods to transmit the gear transmitter to the background. [0003] The original product has the following problems: [0004] 1. The communication port of the original gear transmitter is limited. Some have only one type, and some have two types. When a new device comes in and needs to collect gear information, the communication port of the new device and the gear transmitter If the communication port of the device does not match, it is impossible to directly collect gear information at this time...

Problems solved by technology

[0004] 1. The communication port of the original gear transmitter is limited. Some have only one type, and some have two types. When a new device comes in and needs to collect gear information, the communication port of the new device and the gear transmitter If the communication port of the device does not match, it is impossible to directly collect gear information at this time. It is necessary to contact the background manufacturer to access the gear information from the background. In the power system, this kind of workload will greatly increase;

[0005] 2. When the original gear transmitter has only one communication port, the new device can only contact the manufacturer of the background equipment if it wants to obtain the gear information;

[0006] 3. If the new equipment is an imported product, the required gear information is generally through the current signal of 4-20ma, but only a few models of the existing gear transmitter have current signal output, and most of the output The gear information corresponding to the current value does not match the imported product
