调度中心对管网压力监测的实时性要求很高，但许多压力测点往往不具备供电条件，一般监测设备由于功耗和工作模式的限制，很难满《联系人；欧先生》

足客户的需求。我们依据微功耗测控终端的特点，规划设计了三种工作模式：

◆普通模式

测点具备220V市电或太阳能供电条件，终端设备可以满足数据的频繁采集、频繁传输，并支持数据实时上报和调度中心主动问询。

◆待机模式

测点无供电条件，供电选用可充电大容量蓄电池，由于电池电量限制，需要合理的设置终端设备的数据采集间隔和数据发送间隔。无线发送数据时设备的功耗大，采集时的功耗可以忽略。终端设备支持数据定时上报、数据超限上报和调度中心的主动问询。

蓄电池固定在支架上，外装防水外壳。微功耗测控终端可以检测蓄电池的电压，电压超过下限时，需要对蓄电池进行充电，充电周期与发送频率和选配蓄电池容量相关。1个100Ah的蓄电池一般可以支持终端设备正常工作3—4个月。

◆休眠模式

测点无供电条件，供电选用一次性锂电池组，该电池组安装在微功耗测控终端内。由于电池组的电能有限，终端只能支持数据定时上报和变化上报。终端频繁采集压力等数据与设置的上下限数值进行对比，数据超限时立即上报，数据未超限时存储，等到设定的上报时间一起上报。一组4节的高能锂电池一般可支持设备正常工作1—2年。
