Integrated health monitoring system and method for passenger car air conditioner

Abstract

The invention discloses an integrated health monitoring system for a passenger car air conditioner. A frequency converter voltage sampling signal output end of a passenger car air conditioner frequency converter voltage sampling module of the integrated health monitoring system is connected with an input end of a processor, a temperature data collecting signal output end of a car interior and exterior temperature sampling module is connected with the input end of the processor, an air conditioner stop valve switching value monitoring signal output end of a passenger car air conditioner stop valve switching value monitoring module is connected with an air conditioner stop valve switching value monitoring signal input end, a stored data communication end of a storage device is connected with a stored data communication end of the processor, a health monitoring data output end of the processor is connected with a signal input end of a communication module, a signal output end of the communication module is in wireless communication with a communication end of a network cloud platform via a corresponding wireless Internet-of-Things card, a passenger car registration information mobile input terminal is connected with the network cloud platform, and a database server is connected with the network cloud platform. The integrated health monitoring system can be used for real-time monitoring and after-sale tracking of health condition of the passenger car air conditioner.

Description

technical field [0001] The invention relates to laser cleaning technology, in particular to an integrated health monitoring system and monitoring method for passenger car air conditioners. technical background [0002] With the gradual increase in the use of air conditioners in passenger cars, the monitoring of their operating safety and reliability has become a new subject and difficulty. Traditional air conditioners and inverter air conditioners used in ordinary buses and electric buses will also have the following situations in actual situations: [0003] 1. The water intake of the fan outside the car is short-circuited, causing the fan to burn out. It is necessary to check whether the fan is working normally online in real time. [0004] 2. The voltage of the generator is very unstable. When the voltage is too high, the frequency converter will be burned, and when the voltage is too low, the system will be under-voltage protected. It is necessary to detect the generat...

Problems solved by technology

[0004] 2. The voltage of the generator is very unstable. When the voltage is too high, the frequency converter will be burned. When the voltage is too low, the system will be undervoltage protection.

[0005] 3. Excessive voltage of the generator will cause the PLC of the air conditioner to burn out. It is necessary to detect the bus voltage of the generator in real time, record the data and alarm when it is undervoltage or overvoltage. reason

[0006] 4. The refrigeration efficiency of the air conditioner will decrease with time, and regular maintenance and maintenance are required

[0007] It is very difficult to disassemble and assemble the air conditioner on site. Once a fault occurs, maintenance needs to be time-consuming and labor-intensive to determine the cause of the fault, and the search and replacement cannot be timely and accurate
