According to 1-Fig. 8, flow rate of water flow becomes certain proportional relation with the rotation period of the hydraulic turbine 14, the hydraulic turbine 14 is connected by fixed rotating shaft 13 with microgenerator 12, ac period and the proportional relation of flow rate of water flow that then microgenerator 12 produces, and the square wave cycle that alternating current is after signal transformation circuit is the same with the cycle of alternating current, so microcontroller 311 is after receiving square wave, the cycle of alternating current can be obtained according to the cycle of square wave, thus drawing flow rate of water flow.
According to Fig. 9, the present invention with the use of server end as follows according to the flow process of the carried out leak water detdction of flow rate of water flow:
1, real-time flow rate of water flow Vt is compared with the early warning flow speed value V0 that leaks, if Vt is less than V0, then sending early warning of leaking, this is to monitor the less situation of water leakage, do not tighten such as faucet or phenomenon that water pipe drips, flow with water, but be in the state of dripping, so its flow rate of water flow is very low, and in the ordinary course of things, people, in the process using water, do not have so low flow rate of water flow, are then judged as the phenomenon continuing to leak on a small quantity
2, the long-pending St of Real-time Water fluid is compared with the early warning bulking value S0 that leaks, if St is more than S0, then sending early warning of leaking, this is the situation more in order to monitor water leakage, forgets to close or the phenomenon of water pipe fracture as faucet is kept on all, now, flow rate of water flow is uniform and fast, is constantly in, in unconscious situation, the state of leaking, then after the regular hour, the water volume flow through more than the amount used in everyday of people, then it is determined that the phenomenon continuing to leak in a large number.
Current volume S is multiplied by the cross-sectional area A of the pipeline flow Q=VA obtained by the flow rate of water flow V obtained, and by the flow Q in this period carries out the integration of time T, can obtain current volume S.
Figure 10 is the alternative embodiment of the flow generator 1 that the present invention relates to; Flow generator 1 is connected with pipeline 4, between microgenerator 12 and shell 11, is provided with cavity 16, make current can flow along cavity 16.
The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction; The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement the present invention swimmingly; But, all those skilled in the art without departing within the scope of technical solution of the present invention, utilize disclosed above technology contents and make a little change, modify and the equivalent variations of differentiation, be the Equivalent embodiments of the present invention; Meanwhile, all change of any equivalent variations, modification and differentiation etc. above example made according to the substantial technological of the present invention, all still fall within the protection domain of technical scheme.
