摘　　要：为了有效的进行井地电法勘探,本设计以ARM7系列的LPC2368为主控芯片,配合LCM12864液晶显示屏和4*4阵列式键盘,用C程序设计语言进行了井地电磁发送机嵌入式人机交互软件程序设计,以实现实时更改发送参数,实时监测并调整发送机状态,从而提高勘探精度和效率的目的.针对井地电法勘探中的实际需求,要求电磁发送机人机交互软件能够实现包括修改发送频率、改变发送模式、GPS对钟、显示当前时间及电池电量等功能.经室内及野外实验证明,人机交互软件编程思路新颖,程序运行稳定可靠,能够满足井地电法勘探过程中对发送机的需求,具有一定的借鉴和参考价值.Borehole-to-surface electromagnetic method is a kind of electromagnetic prospecting method which was brought from Russia and applied to the field of reservoir boundary definition and range prediction of profitability of reservoir around the known. The method uses receivers to collect electromagnetic signal on the ground while the transmitter is deployed in the borebole. Electromagnetic transmitter plays a very important role in tile method application while the human-machine interface of transmitter could not be ignored especially. Transmitter serves as a driving source and keeps transmitting inversed square wave into the earth. Howerver human- machine interface takes the responsibility for communication of human and machine in order to determine the feature of eletromagnetie signal transmitted by the machine. Hence it also determine the feature of eletromagnetic signal obtained. This paper used LPC2368 of ARM7 serise, LCM12864 and 4 ＊ 4 array keyboard as hardware base and C language to compose software program. Software of human-machine interface is designed to alter transmition parameters, monitor and regulate the transmittor condition in real time. According to reality needs of borehole-to- surface electromagnetic method, four aspects of transmitter software function have been done-transmition frequencies alteration, transmition mode change, GPS time adjustment, present time and electric quantity of battery display. Tests indoors or outdoors confirmed the performance of human-machine interface of transmittor. Although the sofeware is not as perfect as possible, it has ability to perform reliably and meets the need of electromagnetic transmittor in borehole-to-surfaee electromagnetic prospection.
