In order to solve the problems of information sharing, tampering and leaking in mechanical operation data acquisition, an abnormal data acquisition system for mechanical operation based on block chain technology was designed. The system takes Beihang Chain as the prototype and designs the overall architecture of the system. Data acquisition module uses data acquisition card, CPU, programmable logic device, A/D conversion chip and other equipment to collect and process abnormal data in mechanical operation. The alarm module divides the abnormal data collected by the data acquisition module into five levels: P1-P5. After the implementation of the alarm module, the abnormal information and alarm information in the process of mechanical operation are transmitted to the abnormal data management module for storage. The system adopts the method of mechanical operation anomaly data acquisition based on sparse sampling, and adopts hierarchical clustering method to establish the data acquisition tree of mechanical operation anomaly. The block chain technology is used to design the process of storing and monitoring abnormal data of mechanical operation. The experimental results show that the system has high accuracy of fitting curve for abnormal data acquisition, low real-time energy consumption, and the minimum energy consumption is only 0.01/10-3 J.

Capacitance Tomography

To improve the precision and speed of the system, a new 16-electrode electrical capacitance tomography (ECT) system based on DSP was designed. The measure system adopts 16 electrodes combined and floating capacitance sensor array, and with the phase located loop circuit to eliminate ECT systems additional phase error. The digital signal processor (DSP) is the core of data acquisition system, the computing and control unit includes a DSP (TMS320C5416) and a complex programmable logic device (CPLD). The communication module of the designed system is developed based on HPI parallel transmission technology, which can implement high-speed communication between ECT system and PC. Simulation results show that the sensitivity distribution was more uniform and the reconstructed images for objects were improved obviously by using 16-combined and floating electrodes sensor.
