[Abstract]:The electromagnetic monitoring test satellite (code ZH-1) is to establish a space test platform for monitoring the physical quantities of electromagnetic field, electromagnetic wave, ionospheric plasma, high-energy particle and so on in the global space. It uses these platform monitoring data to identify the electromagnetic, ionospheric and high-energy particle anomalies associated with major earthquakes, providing new technical means for exploring seismic precursor information, space environment monitoring and prediction and Earth system scientific research. Technical preparation for the future establishment of electromagnetic monitoring satellite operational system. High energy particle detector is one of the payloads of electromagnetic monitoring test satellite. ZH-1 satellite high energy particle detector (HEPP) is composed of low energy segment load (HEPP-L), high energy segment load (HEPP-H) and solar X-ray monitor (HEPP-X). The purpose of the high-energy particle detector is to realize the measurement of the incident direction and energy of the high-energy charged particle, and to combine with the space electromagnetic measurement. The HEPP-L data acquisition system is an important part of the high energy particle detector. It is connected to the data management system through the cable, it needs to collect, convert and process the low energy proton and electron generation, and send the processed data to the data management system, at the same time, it needs the high voltage. Current and temperature are monitored, and then the monitored data is sent to the data management system, and it needs to execute the instructions sent by the data management system. This paper mainly introduces the design and implementation of HEPP-L data acquisition system, including: 1. In the part of detector design, the structure, function and related index of silicon wafer detector and anti-coincidence detector are expounded. In the part of hardware design, the partition of each functional module of the system is completed, and the principle of each functional module and the function and performance of each chip are described in detail for these functional modules. In the part of software design, the functional requirements, performance requirements and reliability requirements of the software are introduced, and then the functional modules of the software are divided and the design of each functional module is introduced in detail. In the part of system testing, the hardware and software are mainly tested. The hardware test is mainly to test the functional modules and performance requirements of four circuit boards, and the software part is mainly to test the three main functions of the FPGA software.
