The core idea is as follows: the temperature in a compressor cavity of an air conditioner outdoor unit to be detected on a production line conveyor belt in a commodity inspection room is detected through a temperature sensor tool to serve as an ambient temperature, a standard difference value of the temperature of a compressor winding and the exhaust temperature of the compressor in the same running state as that of the outdoor unit to be detected at present at the corresponding ambient temperature stored in an outdoor unit system is quoted, the standard value of the temperature of the compressor winding is calculated by combining the exhaust temperature detection value, and the difference value is calculated based on the standard value and a calculation value obtained through a winding temperature calculation program and serves as a calibration value of the.
Example 1:
the temperature sensor frock that is applied to commodity inspection room that this embodiment provided includes: temperature sensor and control system, as shown in fig. 1, the control system 1 is a control system of a commodity inspection room, the device carries out data interaction with an electric control component 3 of an air conditioner outdoor unit 2 to be detected through a data transmission line 4, acquires and obtains relevant parameters (such as voltage, current, working frequency and the like) of the air conditioner outdoor unit 2 for performance detection, in order to realize detecting the local temperature in the compressor cavity 6 of the outer machine 2 of waiting to detect of production line conveyer belt 9 in the commodity inspection room, the staff can manually place the probe 7 of temperature sensor near the compressor body 8 in the compressor cavity 6, the temperature sensing signal of probe 7 sends to the temperature sensor main part through temperature sensor data line 5 and gathers, the main part transmits temperature data for control system 1 again, make control system 1 can acquire the local temperature in the compressor cavity 6 of the outer machine 2 of air conditioner. After the temperature data acquisition is completed, the probe 7 is manually withdrawn, and then the local temperature of the compressor cavity of the next air conditioner external unit 2 to be detected on the production line is detected.
Example 2:
compare embodiment 1, in order to realize carrying out the automated inspection to compressor intracavity local temperature, improve detection efficiency, practice thrift the human cost, the temperature sensor frock in this embodiment has still increased position guiding mechanism, sets up temperature sensor on position guiding mechanism, waits to detect when waiting on the production line conveyer belt in the commodity inspection room that the outer machine of air conditioner reachs corresponding position, and position guiding mechanism moves, places temperature sensor and waits to detect the compressor intracavity of the outer machine of air conditioner, gathers compressor intracavity local temperature.
As an implementation means, as shown in fig. 2, the position adjusting mechanism may include a loop conveyor 10 and a robot arm 11, the robot arm 11 is fixed to a conveyor belt of the loop conveyor 10 and can run along a loop-shaped running track of the loop conveyor 10, a main body portion of the temperature sensor is fixed to the fixed end of the robot arm 11, and the probe 7 is disposed at a distal end of the robot arm 11. When the air conditioner external unit 2 to be detected reaches a specific position along with the transmission of the production line conveyor belt 9 (the position is near the adjusting mechanism on the production line conveyor belt and can ensure that the probe is placed in the position in the compressor cavity of the air conditioner external unit to be detected after the mechanical arm is stretched out), the position adjusting mechanism acts to stretch out the mechanical arm 11, so that the probe 7 at the tail end can be positioned in the compressor cavity 6 of the air conditioner external unit 2 to be detected, and when the production line conveyor belt 9 transmits the external unit to the position where the probe 7 is close to the compressor body 8, the clip-shaped transmission device 10 runs at the same speed as the production line conveyor belt 9. Therefore, the probe 7 moves along with the air conditioner external unit 2 to be detected, and sufficient sensing time is guaranteed for acquiring temperature data, so that the acquisition accuracy is improved. Because the mechanical arm 11 moves along with the conveyor belt of the clip-shaped conveyor 10 in a 'clip' shape, after the probe 7 keeps moving for a period of time with the air conditioner external unit 2 to be detected, the probe will be separated from the air conditioner external unit 2 to be detected and return to the position corresponding to the inlet of the production line conveyor belt in the commercial inspection room, so that the probe 7 can be automatically recovered and used for detecting the temperature of the air conditioner external unit 2 to be detected later.

When the position adjusting mechanism detects that the front part passes through the air conditioner external unit 2 to be detected, the mechanical arm 11 is extended out, so that the probe 7 on the mechanical arm 11 is close to the compressor body 8 of the air conditioner external unit 2 to be detected, temperature detection in the cavity is carried out, and the mechanical arm 11 is retracted after the temperature detection is finished.

a winding temperature calculation value is calculated by starting a compressor winding temperature calculation program and based on the current relevant parameters of the air conditioner outdoor unit acquired from an outdoor unit electric control system (the method for acquiring the winding temperature calculation value of the compressor is described in detail in patent CN201610808947.4 of the company, and is not described again here);
and finally, taking the difference value between the winding temperature standard value and the winding temperature calculated value as a calibration value of the compressor winding temperature under the environment temperature and the same running state, and storing the calibration value into a control system of the air conditioner outdoor unit.
