Embodiment Construction
[0033] The embodiment of the present application provides a temperature simulation detection device and system for the electric control board of an air conditioner, which is used to solve the problem that the existing simulation temperature detection uses manual replacement of the resistance to change the resistance value to simulate different temperatures. Inefficient technical problems.
[0034] More specifically, air conditioners are one of the most common temperature control devices in modern society. As the core electronic control board of the equipment, its detection efficiency has a direct impact on the production efficiency of air conditioners. The temperature simulation test is to test the accuracy and efficiency of the air-conditioning electric control board for temperature data processing.
[0035] The temperature data processed by the air conditioner electric control board is actually the resistance value of the temperature sensor. In practical applications, the th...

The invention discloses a temperature simulation detection device and system of an air conditioner electric control plate. Virtual resistance with different resistance is acquired according to an incident relation between a resistance value and a PWM duty ratio and determined reference resistance and by combining PWM signals with variable duty ratios and is used for substituting resistance of resistance-fixed entity to perform temperature simulation detection of the air conditioner electric control plate, the defect that temperature simulation detection of an existing air conditioner electronic control plate needs to replace entity resistance to change test resistance is prevented, and the technical problem of low detection efficiency caused by an existing simulation temperature detectionmode is solved.
Description
technical field [0001] The present application relates to the technical field of hardware testing, in particular to a temperature simulation detection device and system for an air-conditioning electric control board. Background technique [0002] With the progress of society, a new air conditioner product has to go through many steps of testing before being sold to the market, one of which is called Control Logic Test (CLTS). The control logic test of the electric control board is mainly to analyze the operating mechanism of the controller. By comparing it with the actual operating logic, it can be known whether the control logic of the electric control board is normal. [0003] The control logic detection items of the electric control board include the analog temperature detection, specifically the temperature values collected by the temperature sensors in different parts of the artificially simulated air conditioner during operation, and the temperature values are inpu...
