【摘要】：地震帶給人民和社會(huì)帶來(lái)的危害是不可預(yù)估的,對(duì)地震的有效預(yù)報(bào)已經(jīng)成為各個(gè)國(guó)家亟待解決的問(wèn)題之一。在空間帶電粒子探測(cè)方面,全球的實(shí)驗(yàn)觀測(cè)取得了很大的進(jìn)展:首先是俄羅斯的MARIYA空間探測(cè)器發(fā)現(xiàn)了高能粒子暴可能與地震的產(chǎn)生有關(guān)聯(lián)。MARIYA探測(cè)器發(fā)現(xiàn)高能粒子暴經(jīng)常出現(xiàn)在地震發(fā)生前的幾十分鐘到幾個(gè)小時(shí)。而后此現(xiàn)象陸續(xù)被GAMMA和SAMPEX(PET)等衛(wèi)星證實(shí)。粒子暴作為地震潛在的確定性這一現(xiàn)象吸引了國(guó)內(nèi)外地震研究專家的高度關(guān)注。電磁監(jiān)測(cè)試驗(yàn)衛(wèi)星(ZH-1)是我國(guó)首顆與地震探測(cè)相關(guān)的衛(wèi)星。高能粒子探測(cè)器是電磁監(jiān)測(cè)試驗(yàn)衛(wèi)星的有效載荷之一,目的在于研究500公里衛(wèi)星軌道高度上各種因素導(dǎo)致的空間帶電粒子通量或能譜變化的規(guī)律,同時(shí)尋找可能與地震有關(guān)的空間帶電粒子暴,并研究其特征參數(shù)和變化規(guī)律。由于所測(cè)能區(qū)范圍較寬,所以探測(cè)器分為低能段載荷和高能段載荷,分別實(shí)現(xiàn)不同能區(qū)范圍的測(cè)量。高能粒子探測(cè)器低能段載荷目的是對(duì)低能區(qū)粒子實(shí)現(xiàn)高精度測(cè)量,實(shí)現(xiàn)質(zhì)子2-20MeV,電子0.1-3MeV的測(cè)量。低能段載荷中數(shù)據(jù)處理系統(tǒng)是載荷的子系統(tǒng)之一,是電子學(xué)的重要組成部分,主要負(fù)責(zé)對(duì)打入探測(cè)器內(nèi)的粒子能量進(jìn)行采集及處理,控制探測(cè)器工作狀態(tài)并實(shí)現(xiàn)對(duì)一些參量的監(jiān)測(cè),以及完成將粒子能量和其他參量形成的不同數(shù)據(jù)傳遞給數(shù)管系統(tǒng)的任務(wù)。本文主要介紹了對(duì)低能段載荷數(shù)據(jù)處理系統(tǒng)的研制過(guò)程和具體實(shí)現(xiàn),主要包括:1.通過(guò)對(duì)高能粒子探測(cè)器低能段載荷功能極其性能的研究,并結(jié)合探測(cè)器部分的結(jié)構(gòu)和特點(diǎn),制定了數(shù)據(jù)處理系統(tǒng)的所要達(dá)到的功能參數(shù)和性能。2.在數(shù)據(jù)處理系統(tǒng)硬件設(shè)計(jì)階段,完成了系統(tǒng)功能模塊的劃分,電路的搭建。通過(guò)閱讀航天規(guī)范和航天禁限工藝,并結(jié)合探測(cè)器特點(diǎn)完成了原理圖和PCB的設(shè)計(jì)。3.在數(shù)據(jù)處理系統(tǒng)軟件設(shè)計(jì)部分,完成了軟件部分功能模塊的劃分,通過(guò)閱讀芯片數(shù)據(jù)手冊(cè)以及按照航天代碼的設(shè)計(jì)規(guī)范編寫(xiě)了軟件代碼,實(shí)現(xiàn)了對(duì)芯片的時(shí)序控制以及完成了內(nèi)部邏輯的實(shí)現(xiàn),并完成了每個(gè)模塊的仿真,為其在實(shí)際電路工作中奠定了基礎(chǔ)。4.在測(cè)試階段,完成了對(duì)硬件芯片的測(cè)試,軟件邏輯的測(cè)試,并且完成了系統(tǒng)級(jí)的測(cè)試,進(jìn)行了與其他系統(tǒng)的聯(lián)調(diào)測(cè)試,驗(yàn)證數(shù)據(jù)處理系統(tǒng)的功能和性能。測(cè)試覆蓋了整個(gè)探測(cè)器的功能。高能粒子探測(cè)器低能段載荷數(shù)據(jù)處理系統(tǒng)的研制和設(shè)計(jì)工作目前已經(jīng)滿足低能段載荷對(duì)數(shù)據(jù)處理系統(tǒng)的要求,硬件電路和軟件代碼已經(jīng)基本定型,為系統(tǒng)轉(zhuǎn)正樣件提供了堅(jiān)實(shí)的基礎(chǔ)。同時(shí)也為其他數(shù)據(jù)處理系統(tǒng)提供經(jīng)驗(yàn)和參考。
[Abstract]:The harm that earthquake brings to people and society is unpredictable, and the effective prediction of earthquake has become one of the problems to be solved urgently in every country. In space charged particle detection, Great progress has been made in global experimental observations: first, Russia's MARIYA space probe has discovered that high-energy particle bursts may be associated with the occurrence of earthquakes. The MARIYA detector found that high-energy particle bursts often occur before earthquakes occur. Dozens of minutes to a few hours. This phenomenon has since been confirmed by satellites such as GAMMA and SAMPEXPet. As a potential certainty of earthquake, particle burst has attracted great attention of seismic researchers at home and abroad. ZH-1 is the first satellite related to seismic detection in China. The high-energy particle detector is one of the payloads of the electromagnetic monitoring test satellite, the purpose of which is to study the variation of the flux or energy spectrum of charged particles in space caused by various factors at the altitude of the satellite orbit of 500 km. At the same time, the space charged particle bursts which may be related to earthquakes are searched, and their characteristic parameters and variation laws are studied. Because of the wide energy range, the detector can be divided into low energy section load and high energy band load. The purpose of the high energy particle detector is to measure the particles in the low energy region with high precision, and to measure the protons at 2-20 MeV and the electron 0.1-3MeV. The data processing system is one of the subsystems of the load in the low energy section. It is an important part of electronics. It is mainly responsible for collecting and processing the energy of particles in the probe. It controls the working state of the detector, monitors some parameters, and accomplishes the task of transferring different data formed by particle energy and other parameters to the multitube system. This paper mainly introduces the development and implementation of the data processing system for low energy load, including: 1. Based on the study of the function and performance of the high-energy particle detector in the low energy section, and combining the structure and characteristics of the detector, the functional parameters and performance of the data processing system are established. In the phase of hardware design of data processing system, the partition of system function module and the construction of circuit are completed. By reading the spaceflight specification and spaceflight interdiction process, the schematic diagram and the design of PCB. 3 are completed in combination with the characteristics of the detector. In the software design part of the data processing system, the partition of the function modules of the software is completed, and the software code is written by reading the data manual of the chip and according to the design specification of the aerospace code. The timing control of the chip and the realization of the internal logic are realized, and the simulation of each module is completed, which lays a foundation for the actual circuit work. 4. In the testing stage, the hardware chip test, software logic test, system-level test are completed, and the joint test with other systems is carried out to verify the function and performance of the data processing system. The test covers the entire function of the detector. The development and design of data processing system for low energy segment load of high energy particle detector has met the requirements of data processing system for low energy segment load at present, and the hardware circuit and software code have been basically finalized. It provides a solid foundation for the system transposition. At the same time, it also provides experience and reference for other data processing systems.
