开关柜无源无线测温系统功能特点
Functional characteristics of a passive wireless temperature measuring system in a switchgear cabinet
1) 多种温度监测方式
1) various temperature monitoring methods
系统设定自动采集任务，定时按照既定的采样频率进行开关柜温度信息的采集。温度数据保存在数据库中，用户可以设定时间区间、指定监控对象进行历史温度信息的查询。
The system sets the automatic acquisition task and periodically collects the temperature information of the switchgear according to the established sampling frequency. The temperature data is stored in the database. Users can set time intervals and specify monitoring objects to query historical temperature information.
同时，用户可以在主站系统中指定某一具体的开关柜或传感器进行实时的温度信息采集。
At the same time, the user can specify a specific switch cabinet or sensor in the master station system to collect real-time temperature information.
2) 完备的报警机制
2) complete alarm mechanism
当开关柜温度的绝对值或温度的变化率超过上限，系统为运行管理人员提供声音、光电、短信等多种方式的告警信息。及时或预知性的发现和排除故障，从而最大限度的保障电力设备的安全稳定运行。
When the absolute or temperature change rate of the switch cabinet exceeds the upper limit, the system provides alarm information in a variety of ways, such as sound, photoelectric, SMS and so on. Timely or foresight of the discovery and troubleshooting, thereby maximizing the safety and stability of power equipment operation.
3) 完善的系统参数设置
3) perfect system parameter setting
建立各级开关柜温度监测及管理网络，管理温度监测相关的开关柜、传感器、读入器等各类设备档案。
Establish temperature monitoring and management network of switchgear at all levels, and manage all kinds of equipment files such as switch cabinet, sensor, reader and so on.
指定开关柜或一个具体的温度传感器进行参数的远程下发，包括传感器温度校准、各类预警值、时间、温度采集频率、传感器发射功率、信号接受门限等。
The switch cabinet or a specific temperature sensor can be used for remote transmission of parameters, including sensor temperature calibration, various warning values, time, temperature acquisition frequency, sensor transmission power, signal acceptance threshold, and so on.
