Abstract

The embodiment of the invention discloses a test system used for an electric current loop communication circuit and an air conditioner. The test system used for the electric current loop communicationcircuit comprises a first communication circuit, a second communication circuit and a control unit. The first communication circuit is connected with a second to-be-tested circuit, and the second communication circuit is connected with a first to-be-tested circuit. The control unit comprises a switching circuit and a controller connected with the switching circuit. The switching circuit is connected with the first communication circuit and the second communication circuit. The controller controls the switching circuit, so that a first test loop is formed by the first communication circuit andthe second to-be-tested circuit, or a second test loop is formed by the switching circuit, the second communication circuit and the first to-be-tested circuit so as to test the second to-be-tested circuit or the first to-be-tested circuit. The technical problems that in the correlation technique, the first to-be-tested circuit and the second to-be-tested circuit of the electric current loop communication circuit are tested by two board cards correspondingly, and consequently cost is increased are solved.

Description

technical field [0001] The embodiments of the present application relate to the field of current loop communication, and in particular, relate to a test system and an air conditioner for a current loop communication circuit. Background technique [0002] Industrial control often involves long-distance and accurate transmission of data. Using current as a carrier to transmit data can increase the noise tolerance of the signal and improve the anti-attenuation ability of the signal. Taking the inverter air conditioner as an example, it is divided into an indoor unit installed indoors and an outdoor unit installed outdoors. The inner unit has an inner unit board for receiving remote control signals and controlling indoor fans and other loads. The first control board is set on the inner unit board. There is an external machine board for driving the compressor inside the external machine, and a second controller and a second circuit to be tested are arranged on the external machin...
