概述电源站是SN368数字地震仪采集站的供电设备。施工时,用电缆把电源站串接在排列中,以12V电瓶作能源,由主机启动,产生48V电压,作为采集站的电源。电源站由三部分组成1.接口:主要是把大线中的虚对线电压GP_1、GP_2,输至电源控制板,作为电源站的启动信号。2.开关电源板:它由电源控制板产生的控制信号OVLC、PSON控制,产生48V电压,并提供各种检测信号给电源控制板。3.电源控制板:产生启动信号、停止信号、斩波控制信号,用来控制电源板,使其输出故障报警信号。
Power station is SN368 digital seismograph collecting station power supply equipment. Construction, the cable to the power station connected in series in order to 12V battery for energy from the host start to produce 48V voltage, as the power supply station. Power station consists of three parts 1. Interface: The main line is the virtual line voltage GP_1, GP_2, power control board, as the power station start signal. 2. Switching Power Supply Board: It is controlled by the power control board OVLC, PSON control, resulting in 48V voltage, and provide a variety of test signals to the power control panel. 3. Power control board: generate start signal, stop signal, chopper control signal, used to control the power board, so that it outputs a fault alarm signal.
