Measuring device for detecting resistors in air-condition circuits automatically

Abstract

The invention relates to a measuring device for detecting resistors in air-condition circuits automatically, which comprises a measuring main circuit module, a display module and a buzzer alarming module. The measuring device is characterized in that the measuring device comprises a clamp for clamping a measured air-condition circuit board; a plurality of pairs of thimbles on the clamp contact both ends of the resistors on the measured air-condition circuit board respectively, so that the resistors are respectively connected to the respective measured circuit; voltage signals are extracted by the thimbles and are connected to each signal input end of the main circuit module; the main circuit module calculates a value of each measured resistor according to a voltage value of each inputted signal and a line and an element parameter of each measured circuit and compares the value of each measured resistor with a design value of each resistor; and the signal output end of the main circuit module is connected to the display module and the buzzer alarming module, so that a comparison result is displayed and subjected to alarm reminding. The measuring device has the advantages of simple structure, low cost, accurate detection, convenient and quick operation and capability of improving the production efficiency.

Description

technical field [0001] The invention relates to a resistance measuring device for an air-conditioning controller, which is used for measuring the resistance value of the air-conditioning controller. Background technique [0002] At present, each set of controllers in the production process must detect whether the high, medium and low wind speed and temperature detection circuits are normal. [0003] High, medium and low wind speeds are determined by the resistance value of the wind speed selection resistor, and whether the temperature detection is accurate depends on whether the resistance value of the reference resistor is accurate. The original way to select whether the resistance of high, medium and low wind speed is correct is to connect the fan motor, and then use the wind speed detection tool to check whether the wind speed is correct, but this method is extremely inconvenient to operate on the assembly line, and it takes a long time to operate. The reference resistan...

Whether the selection resistance of high, medium and low wind speed is correct, the original method is to connect the fan motor, and then use the wind speed detection tool to check whether the wind speed is correct, but this method is very inconvenient to operate on the assembly line, and it takes a long time to operate

The reference resistance of the temperature detection circuit cannot be detected in production, resulting in a large deviation between the temperature detection and the actual temperature
