Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
By shown in Figure 1, the utility model is by two radar wave current meter 1-1,1-2, serial ports 2, and microprocessor 3, LCD display 7, USB interface 4 and server 6 form.
A pair of radar wave current meter 1-1,1-2 are over against the water (flow) direction setting, this all is 20 ° of settings with river surface to the radar wave current meter, the signal output part of radar wave current meter all is connected with microprocessor 3 input end signals by serial ports 2, the microprocessor 3 outer USB interface 4 that are provided with, be provided with wireless communication module on the USB interface, microprocessor is connected with server 6 signals of far-end by wireless communication module, and wireless communication module utilizes GPRS network 5 and the server 6 of far-end to realize data interaction; Microprocessor 6 also is connected with LCD display 7 signals.
The utility model device is equipped with dual mode to two radar wave current meters: shown in Fig. 2 (a) and Fig. 2 (b), two radar wave current meters flow into or the outflow direction towards current simultaneously, but one is set to survey the current inflow velocity, and another is set to survey the current rate of outflow;
As shown in Figure 3, a radar wave current meter is towards the current inflow direction, and another flows out direction towards current, but all is set to survey the current inflow velocity or all is set to survey the current rate of outflow.
Be that two radar wave current meters distribute identifier separately: wherein main radar electric flow meter (surveying the flow velocity that tidal bore flows to) is designated 1, and auxiliary radar wave current meter (surveying the reverse flow velocity that tidal bore flows to) is designated 0.Two radar wave current meters are issued microprocessor by serial ports by the RS232 interface with instantaneous velocity data and identifier separately respectively.As shown in Figure 4, microprocessor carries out Treatment Analysis to two flow speed datas that record: if data all are empty, instantaneous velocity is 0; If data are empty, another data have value, the identifier of the current meter of these data of the then data of the value of remaining with, and record transmission; If two data have value, then keep the data of higher value, and record sends the identifier of the current meter of these data; Judge the size and Orientation of instantaneous velocity according to the data that keep and identifier: size is the value of these data, if indications is 1, judges that then direction is inflow, if identifier is 0, judges that then direction is outflow.Microprocessor is crossed LCD display with the instantaneous velocity data communication device and is shown, and is sent to the server at hydrometric station by GPRS network by USB interface.
Above by with reference to the exemplary embodiment of in the accompanying drawings expression the utility model having been done special displaying and explanation, to one skilled in the art, should be understood that, not deviating from various modifications and the change of making under thought of the present utility model and the scope in the form and details, all will be the infringement to the utility model patent.So real thought and scope that the utility model will be protected are limited by appending claims.
