Abstract

The embodiments of the present application disclose a testing system and an air conditioner for a current loop communication circuit. Wherein, the test system for the current loop communication circuit includes: a first communication circuit, a second communication circuit and a control unit, the first communication circuit is connected to the second circuit to be tested, and the second communication circuit is connected to the first circuit to be tested; The control unit includes a switching circuit and a controller connected to the switching circuit. The switching circuit is respectively connected to the first communication circuit and the second communication circuit. The controller controls the switching circuit to form the switching circuit, the first communication circuit and the second circuit to be tested. The first test loop, or the switching circuit, the second communication circuit and the first circuit to be tested form a second test loop to test the second circuit to be tested or the first circuit to be tested. The present application solves the technical problem in the related art that the first circuit to be tested and the second circuit to be tested of the current loop communication circuit are respectively tested by using two boards, which leads to increased cost.

Description

technical field [0001] The embodiments of the present application relate to the field of current loop communication, and in particular, to a testing system and an air conditioner for a current loop communication circuit. Background technique [0002] Industrial control often involves long-distance and accurate data transmission. 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 loads such as indoor fans, and the inner unit board is provided with a first control unit. The controller and the first circuit to be tested are provided with an external machine board for driving the compressor, and the external machine board is provided with a second contro...
