Communication parallel test technology

Abstract

The invention discloses a communication parallel test technology, relating to the technical field of communications. The technology comprises a communication host, a signal monitoring module and a feedback module, and the communication host is electrically connected with a signal converter through a wire. The signal converter is electrically connected with a communication slave through a wire; thecommunication host is electrically connected with a main control module, the output end of the main control module is electrically connected with a signal transmission module, the output end of the signal transmission module is electrically connected with a signal conversion module, and the output end of the signal conversion module is electrically connected with a signal receiving module. The beneficial effects of the communication parallel test technology are that: the communication slave is connected with the signal converter through an RS485 interface, the plurality of communication slaves can be allowed to be connected to a bus in the RS485 interface, so that the RS485 interface has the capability of multi-station communication and is suitable for communication parallel connection, and the signal converter is an RS45-RS232 converter and can electrically connect the communication slaves with the communication host and can realize signal conversion.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication parallel test technology. Background technique [0002] Communication has different interpretations in different environments. After the emergence of radio wave transmission communication, communication is simply interpreted as the transmission of information, which refers to the transmission and exchange of information from one place to another, and its purpose is to transmit messages. With the continuous acceleration of the integration of industrialization and informatization, coupled with the continuous increase of government investment in public security, the scale of the private network communication market has continued to expand in recent years. In data transmission, parallel communication is a method of transmitting multiple binary digits at the same time. It is in contrast to serial communication, which transfers one bit at a time. During the comm...

Problems solved by technology

[0004] The purpose of the present invention is to provide a communication parallel test technology to solve the problem that the existing communication parallel test technology proposed in the above-mentioned background technology cannot accurately identify communication slaves with communication failures during the test process, and in the communication In the process of connecting the slave machine with the communication master, it is impossible to convert the signal, which is not convenient for signal identification in the parallel communication process, and it is also impossible to realize the monitoring of the connection status of the data signal and the load of the power signal at the same time.
