[0053] For ease of understanding, the specific structure of the present invention is described below. Figure 1 , Figure 1The present invention provides a block diagram of an ultrasonic cleaning control system. The system includes: a main control chip module 110, a temperature acquisition module 120, a liquid level detection module 130, a control module 140, a display module 150, an alarm module 160 and a data storage module 170, wherein the main control chip module 110 is provided with multiple sampling terminals and multiple output terminals, the temperature acquisition module 120 and the liquid level detection module 130 are respectively connected to the sampling terminals, in practical applications, the temperature acquisition module 120 and the liquid level detection module 130 can be arranged on the same sampling terminal, or on different sampling terminals, and the main control chip module 110 can read or receive the temperature information in the cleaning box and the liquid level information of each liquid surface collected from the temperature acquisition module 120 and the liquid level detection module 130 through the sampling terminal. The control module 140, the display module 150, the alarm module 160 and the data storage module 170 are respectively connected to the output end, and the control module 140, the display module 150, the alarm module 160 and the data storage module 170 are arranged on different output ends. The main control chip module 110 generates corresponding control instructions according to the sampling results of the temperature sampling module 120 and the liquid level detection module 130 to control at least one module among the control module 140, the display module 150, the alarm module 160 and the data storage module 170.

[0054] In this embodiment, the ultrasonic cleaning control system is mainly used on cleaning equipment, which includes a cleaning box, wherein the main control chip module 110, the control module 140, the display module 150, the alarm module 160 and the storage data module 170 are arranged on the outside of the cleaning box and are sealed to a certain extent. The temperature acquisition module 120 and the liquid level detection module 130 are arranged in the cleaning box for real-time collection and monitoring of internal data in the cleaning box, and the main control chip module 110, the temperature acquisition module 120, the liquid level detection module 130, the control module 140, the display module 150, the alarm module 160 and the storage data module 170 are connected to each other through a communication bus.

[0055] The temperature acquisition module 120 is used to collect the liquid temperature and air temperature in the cleaning box, and display them on the display module 150 through the main control chip module 110; specifically, the liquid temperature collected by the temperature acquisition module 120 includes the temperature of water used to clean the objects to be cleaned, the temperature of the cleaning liquid and the temperature of the rinsing liquid, as well as the temperature of the air in the cleaning box.

[0057] The main control chip module 110 compares the liquid temperature, the air temperature and the liquid level with the preset configuration parameters, outputs a cleaning control instruction based on the comparison result, and controls the control module 140 to adjust the liquid and air in the cleaning tank based on the cleaning control instruction; in actual applications, the configuration parameters can be understood as various pre-set temperature thresholds and liquid level thresholds. After the data is obtained by the temperature acquisition module 120 and the liquid level detection module 130, the main control chip module 110 compares the obtained information with the corresponding preset thresholds, and calculates that if the error is within the set error range, it is determined that the cleaning conditions are met, otherwise the conditions are not met, and further output instructions are required to control the control module 140 to adjust various indicators in the cleaning tank.

[0058] When the main control chip module 110 detects that the comparison result is abnormal or the cleaning is finished, an alarm instruction is generated to control the alarm module 160 to send an alarm message; specifically, the abnormal comparison result means that there is at least one alarm percentage below the threshold or above the threshold in the liquid temperature, air temperature and liquid level, so that an alarm instruction is generated based on the abnormal result, that is, a high and low potential output signal to control the output terminal connected to the alarm module 160 in the main control chip module 110 to be connected, and the alarm module 160 outputs an alarm signal.
