Study On The Usability Of Pneumatic High-Speed Wireless Communication System

With the increasing application of wireless communication technology in pneumatic system,the usability of pneumatic wireless communication system is becoming more and more important.Due to the strict requirements of real-time data communication,data transmission delay must be strictly controlled.And the communication of a pneumatic system is different in that the amount of data is always small with much uncertainty,and common communication protocol is difficult to meet these needs,so the study of custom pneumatic high-speed communication protocol has important significance.After analyzing common wireless communication systems,to meet the requirements of data communication in pneumatic system,high-speed wireless communication system is designed.And the usability of high-speed wireless communication system is furtherly studied,the main contents are as follows:First of all,according to the working process,requirements of real-time communication and usability in pneumatic system,the communication delay,data transmission rate and response time are clarified.The transmission rate and delay of communication in common wireless systems is compared to determine the technical path of pneumatic high-speed wireless communication system,and custom high-speed wireless communication protocol based on nRF24L01 is proposed.By defining the delay of communication in pneumatic system,customizing highspeed wireless communication protocol and simulating the conflict of multi nodes communication in industrial pneumatic field,a software development and testing platform for high-speed wireless communication system are built.Keil development environment for is used for program optimization,including SPI data transmission between nRF24L01 and MCU,nRF24L01 dynamic length data frame and so on,to meet the delay requirements.Single node and multi nodes communication are tested and analyzed.The communication success rate and communication delay of single node communication are recorded with different communication distance and data frame length.And communication collision avoidance strategy is added into the protocol and multi nodes network communication collision is tested to test the performance of the collision inhibition strategy.Finally,by researching on the acknowledge response mode,efficient network strategy is designed and the data response error is effectively avoided.The two-way communication of wireless communication system is also completed.Thus the feasibility of the scheme is proved,and it has reference value for the application of the pneumatic wireless communication system.
