Collection terminal communication interface load capacity test system

Abstract

The invention provides a collection terminal communication interface load capacity test system which comprises an alternating current-direct current test power supply, a communication module, a ripple test module, a noise test module, a direct current voltage detection module, a direct current detection module, a load switching control module, a test load and a host computer. The alternating current-direct current test power supply powers the test system and a collection terminal through a power supply interface at the same time. The communication module, the ripple test module, the noise test module, the direct current voltage detection module, the direct current detection module, the load switching control module and the test load are respectively bidirectionally connected with the host computer. The ripple test module, the noise test module, the direct current voltage detection module, the direct current detection module, the load switching control module and the test load respectively communicate with the collection terminal through a communication interface of the communication module. According to the invention, the test complexity is considered; by using communication connection, electrical connection and test connection, different test equipment and tested equipment are associated; and the test requirements of relevant standards are considered, so that the test system has advancement and module adaptability.

Description

technical field [0001] The invention relates to a test method, in particular to a system for testing the carrying capacity of a communication interface of an acquisition terminal. Background technique [0002] At present, China is building an electricity consumption information collection system. The electricity consumption information collection system consists of a master station, collection terminals, and electricity meters. Due to the large scale of the system, the communication modules and communication protocols of domestic terminal manufacturers are developed by the manufacturers themselves. The devices operate independently of each other, and the collection terminals correspond to the communication units one by one. The power supply requirements and loading requirements of the collection terminals are customized and optimized for the matching communication units. . [0003] Nowadays, it is required that the collection terminal needs to be matched with a variety of c...
