Abstract: When the conventional air pressure probe system is applied to the air pressure probe system in complex environment, it has the deficiency of large error and small range of detection. Therefore, the design and implementation of the air pressure probe system is proposed. Based on the design of liquid level detection, bubble detection design, TIP head plug design and hardware block diagram of pneumatic liquid suction detection project, the hardware design of pneumatic liquid suction detection system was completed. Relying on the design of software flow chart and the establishment of RS485 communication protocol, the software design of pneumatic liquid suction detection system is realized. The problem of too little pressure in passive liquid level detection, the problem of normal driving force of TIP head piston and the problem of unknown maximum driving force, etc. The design of the pneumatic suction detection system is realized. The test data show that the proposed detection system is 15.71% lower than the conventional one, and the range of detection is 56.6% higher.
