摘　　要：针对自主研制的新型质子旋进磁力仪的硬件系统的技术特点,结合具体测量中的一些实际情况,基于Microchip公司的PIC16F877A芯片,设计并实现了一套测控软件;系统的介绍了该软件系统各个模块的设计原理与程序流程,分析了其技术特点与优势。并在测量大地总场值的实验中,与加拿大GEM公司生产的DiDd三分量磁力仪测量进行了比较,结果表明我们的新型质子旋进磁力仪在测量精度与准确度上接近DiDd三分量磁力仪,而在成本仪器体积与重量方面,则明显优于DiDd。Based on PIC16F877A （PIC product of Microchip company） and technical characteristics of a new-type proton-precession magnetometer we designed, we proposed a measurement and control software system. The design theory and program flow as well as its technical features and superiority over the old-type magnetometer are introduced in details. In the experiment, we compared the instrument with DiDd three-component magnetometer. The result shows that the new-style proton-precession magnetometer we designed is approaching DiDd three-component magnetometer on the measuring precision, whereas it is better than DiDd three- component magnetometer on the cost, volume and weight.
