specific Embodiment 1

[0061] For example, there are 5 ports on the motherboard of a certain type of air conditioner for detecting the exhaust temperature, such as 1# port, 2# port, 3# port, 4# port and 5# port, to detect the voltage value of each port, the first The first voltage threshold is a preset voltage value obtained from experiments, such as 0.05V, and the second voltage threshold is also a preset voltage value obtained from experiments, such as 4.95V, and the voltage value is between 0.05V~4.95V (such as 3V), indicating that the port is connected to an exhaust gas temperature sensor and the port status is normal. For example, the port status of 1# port, 2# port and 3# port is normal, and the number of ports that determine the port status is normal is 3 , the voltage values ​​of the remaining 2 ports, 4# port and 5# port, are both lower than the first voltage threshold, that is, the state of the remaining 2 ports is open circuit state, and the exhaust gas temperature sensor is not connected....

For example, the port status of 1# port and 2# port is normal. The number of ports that confirm the port status is normal is 2. The voltage value of the port is greater than the second voltage threshold, indicating that the port is in a fault state, and the voltage values ​​of the other two ports, namely 4# port and 5# port, are both lower than the first voltage threshold, that is...

Abstract

The invention provides a main board control logic identification method and device and an air conditioner. The main board control logic identification method is used for the air conditioner. The main board control logic identification method comprises the steps that after a main board runs preset time, the voltage value of at least one port which is used for detecting the exhaust gas temperature is determined, and control logic of the main board is determined and executed according to the port state corresponding to the voltage value. According to the technical scheme, identification of the control logic of the main board can be achieved, the universality of the main board is improved, achievement of standardized production of the main board is feasible, the production efficiency is improved, manpower and material resources are saved, and the possibility that errors are caused by human factors is reduced.

Description

technical field [0001] The present invention relates to the field of air conditioners, in particular to a motherboard control logic identification method, a motherboard control logic identification device, a computer device, a computer-readable storage medium and an air conditioner. Background technique [0002] At present, for different types of air conditioners, some air conditioners are designed with an exhaust temperature sensor to detect the exhaust temperature and the main board of the air conditioner executes the corresponding control logic with the exhaust temperature sensor, while some air conditioners do not have an exhaust temperature sensor. The main board executes the control logic corresponding to the exhaust temperature sensor. In order to solve the above problems, the existing technology generally designs different main boards for different types of air conditioners, and the main boards correspond to the air conditioner models one by one, or designs a univers...
