TM-3电台电源故障及改进方法

Power breakdowns of TM-3 transmitter-receiver and improvement approaches

TM-3电台是Trimble5700GPS测量系统中实时动态测量的数据传输工具,具有操作方便、稳定性强、数传率高的特点。随着仪器使用年限的增加,电台的故障也越来越频繁,主要表现为电源故障。通过在电路中串联一个二极管,并联一个压敏电阻并将电源线保险换成电源保险装置,解决了电台电源故障问题。

TM-3 transmitter-receiver is data transmission tool of real-time kinematical measurement in Trible 5700 GPS measurement system and is characterized by feasible operation, strong stability and high data transmission rate. Along with the service life of instrument increasing, the breakdown of transmitter-receiver more and more frequently occurred, mainly in power. By series of a diode and parallel of a pressure-sensitive resistance in circuit and changing the fuse in power line into power security unit, the issue of breakdown in transmitter-receiver power was solved.
