Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Shown in Fig. 1 and Fig. 2, according to embodiments of the invention, cistern water level detection method comprises: the total Water detecting water tank; The inflow of real-time detection water tank and aquifer yield, and the accumulative inflow and the accumulated outflow that calculate water tank; Determine the water level in water tank.
After the total Water knowing water tank, based on this, the inflow of real-time detection water tank and aquifer yield, just can calculate the remaining water yield in water tank in real time, thus the water level in water tank can be determined, and determining the need of moisturizing with this, the water level of moisturizing is determined more accurate, moisturizing water level can be more reasonable.
By this cistern water level detection method, the water yield in water tank can be detected in real time according to the inflow of the total Water of water tank and water tank and aquifer yield, realize the real-time examination and controlling to water level in water tank, realize the stepless detection to cistern water level, structure is simple, testing result accurately and reliably, good stability.
The step detecting the total Water of water tank comprises: the water in emptying water tank; Close rising pipe 7, open water inlet pipe 6, by water level switch 1 sensed water level, moisturizing is carried out to water tank; Stop water tank moisturizing when Water in Water Tank is full, calculate the accumulation discharge of water inlet pipe 6, determine the total Water of water tank.By this kind of mode, can calculate water tank and to full water process, enter how many water yield from complete sky, this water yield is exactly the total Water of water tank.The water yield cheek method of this kind of water tank is simple, and cost is lower, and measurement result accurately and reliably, can obtain water tank accurately and indulge water yield data.
The step detecting the total Water of water tank completes under water tank debugging mode.Water tank has debugging mode and normal mode of operation, under the debugging mode of water tank, needs the water valve of closing rising pipe, and is emptied completely by the water in water tank, thus determine the total Water of water tank.In the normal mode, water inlet pipe and rising pipe are all opened, and the water yield flow through by statistics water inlet pipe and rising pipe determines the remaining water yield in water tank.After water tank being divided into these two kinds of patterns, make the control operation of water tank definitely, step is more reasonable, confusion is less likely to occur, the data accurate and effective more of acquisition.
After the total Water determining water tank, record and store this numerical value, then water tank proceeds to normal operating condition.By memory chip record and the total Water of storage tank, be to prevent loss of data after power down, ensureing reliability and the integrality of data.
Cistern water level detection method detects the full state of Water in Water Tank by float-ball type water level switch 1.Float-ball type water level switch 1 can SEA LEVEL VARIATION better in detection of dynamic water tank, and detect sensitive, testing result is reliable.
Cistern water level detection method detects inflow by flow of inlet water sensor 2, detects the water yield by water flow sensor 3.By the mode that float-ball type water level switch and flow sensor be combined with each other, stepless water level detecting can be realized better, real-time level monitoring, for the timely moisturizing of water tank provides foundation accurately and reliably.
Determine that the step of the water level in water tank comprises: in the normal operating mode, real-time progressive the surplus water calculated in water tank, wherein L
in real time=L
water tank+ water inlet pipe integrated flux-rising pipe integrated flux, wherein L
water tankfor the total Water in water tank; Determine water level number percent, its middle water level number percent=water yield number percent=L
in real time/ L
water tank* 100%.
According to embodiments of the invention, device for detecting water level of water tank comprises: water level switch 1, the full state of the water for detecting water tank; Flow of inlet water sensor 2, is arranged on water inlet pipe 6 place, for determining the flow of inlet water entered through water inlet pipe 6 in water tank; Water flow sensor 3, is arranged on rising pipe 7 place, for determining the water flow flowed out through rising pipe 7 in water tank; Water replanishing device 4, is connected to water inlet pipe 6; Controller 5, is connected to water level switch 1, flow of inlet water sensor 2, water flow sensor 3 and water replanishing device 4, detects and controls the water level in water tank.
The state that controller can set water tank is debugging mode or normal mode of operation, and the real time water level in the data determination water tank that can transmit according to flow of inlet water sensor 2, water level switch 1, water flow sensor 3, then after the water level in water tank arrives predeterminated position, timely control water replanishing device 4 pairs of water tanks carry out moisturizing, keep water tank normally to work.
Water level switch 1 is preferably float-ball type water level switch.This water level switch also can detect the pick-up unit of water tank full water state for other.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
