摘要
研制能提供DC 24 V、DC 12 V两种电源的电源柜。该电源柜自带蓄电池,具备车辆发动机、车载发电机组、外接民用交流电向蓄电池充电功能,具备一个或多个音像通道单独或同时开、关功能,能够保障蓄电池电量充足,满足不同应用场景下选择使用各音像通道,适应系统升级为DC 24 V、DC 12 V设备的需要,解决了现有车载音像监控系统存在的惯性问题,实际应用效果良好。
A power supply cabinet is developed that can provide both DC 24 V and DC 12 V power supply.The power supply cabinet comes with a battery and has the functions of charging the battery by vehicle engine,vehicle generator set and external civil AC power,one or more audio-visual channels can be turned on and off independently or simultaneously.It can ensure that the battery has sufficient power,meet the needs of selecting audio-visual channels in different application scenarios,meet the needs of upgrading the system to DC 24 V and DC 12 V devices,and solve the inertia problem of the existing vehicle-mounted audio-visual monitoring system.The actual application effect is good.
