Embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the structure of the utility model is not limited only to following examples:
Like Fig. 1, shown in Figure 2; Low-power consumption hydrological telemetering terminating machine; Comprisewaterproof cabinet 1,main frame 2,solar panels 3 andaccumulator 11,main frame 2 is arranged in thewaterproof cabinet 1 withaccumulator 11, andsolar panels 3 are arranged on outside thewaterproof cabinet 1;Solar panels 3 are electrically connected withmain frame 2 withaccumulator 11; It is characterized in that: describedmain frame 2 comprisescore cpu unit 6 and the acquisition controlling unit 7,data communication units 8,charging control unit 10,PMU 12 and the human andmachine interface unit 13 that are connected withcore cpu unit 6, andcharging control unit 10 connectssolar panels 3 andaccumulator 11 respectively, anddata communication units 8 can connect the monitoring center of far-end through GPRS wirelessdata sending unit 9; Can also be connected to monitoring center through standby communication facility, standby communication facility can be communication facilitiess such as satellite communication terminal.
Described human andmachine interface unit 13 comprises a display and a supervisory keyboard.
Be connected withrain gage 4 andwater level gauge 5 on the acquisition controlling unit 7 of the utility model,rain gage 4 is arranged on outside thecabinet 1 withwater level gauge 5, and describedrain gage 4 is the tipping-bucket rain-gauge of single contact or double-contact;Water level gauge 5 is the float type level meter of 13 Gray code outputs.
Rain gage 4 is to interrupt carrying out stored counts through tipping bucket signal triggeringcore cpu unit 6, andcore cpu unit 6 passes through cumulative data calculating real-time rainfall amount, and sends data to storer 14 and display;Water level gauge 5 is controlled at interval at setting-up time bycore cpu unit 6 and is gathered, and sends data to storer 14 and display.
Also be connected with astorer 14 on the describedcore cpu unit 6.
The position that is right against display on the describedwaterproof cabinet 1 also is provided with view window, and the staff observes the data of current collection through view window.
When there was sunshine the outside, thesolar panels 3 of the utility model can be worked, and charged through 10 pairs ofaccumulators 11 of charging control unit, simultaneously this device were supplied power; The outside all the time according to the time, 3 of solar panels can not be worked,accumulator 11 is this device power supply.
Thesolar panels 3 of the utility model,rain gage 4 andwater level gauge 5 all are connected on themain frame 2 through cable; When connecing intowaterproof cabinet 1, adopts by the cable onsolar panels 3,rain gage 4 and thewater level gauge 5 cable waterproof head turnover line; Classification of waterproof reaches IP66, satisfies the needs of field work.
