Embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

A kind of changeable water supply controller, connected and composed by cabinet and private water supply control circuit, as shown in Figure 1, on casing front panel, be provided with two-way LED nixie display LA, configuration switch S1, water yield configuration switch S2, function setting switch S 3, reset switch S4, start button K1, stop button K2, automatic, manual change-over switch K3, power switch KT.Water supply control circuit, as shown in Figure 2, comprise single-chip microcomputer N1, flow sensor LL, configuration switch S1, water yield configuration switch S2, function setting switch S 3, reset switch S4, start button K1, stop button K2, automatically, manual change-over switch K3, valve relay JR1, time relay JR2, time relay JR3, nixie display LA.Single-chip microcomputer is connected with flow sensor by I/O interface for gathering actual water flow signal, single-chip microcomputer by I/O interface respectively with start button K1, stop button K2, automatically, manual change-over switch K3 is connected and realizes respectively automatic water-supply, stop supplying water and manually supply water and wait operation to control function, single-chip microcomputer is respectively by three I/O interfaces and water yield configuration switch S1, water yield configuration switch S2, function setting switch S 3 is connected, reset switch is connected with single-chip microcomputer input port, single-chip microcomputer is set each water supply quantity by these 4 switches, flow sensor parameter, and output control mode, supply flow rate can be set arbitrarily.Single-chip microcomputer output terminal is connected and realizes respectively valve switch control function with valve relay JR1, charactron display LA.

In above-mentioned changeable water supply controller, K3, in the time of manual mode, starts automatic water-supply after pressing the time delay of start button K1 elapsed time relay J R2, JR3, and delay time can be set by actual requirement, also can not time delay.Single-chip microcomputer calculates corresponding umber of pulse according to water yield setting value, and flow sensor output is counted, and sends instruction shutoff solenoid valve and stop supplying water in the time counting to setting value, realizes quantitative automatic water supply function.Whenever press and stop stopping immediately supplying water after button K2.K3, in the time of automated manner, can directly be connected on enabling signal K1 upper, realizes full automatic water supply, does not need personnel to operate.Thereby after the power-off of the built-in data-carrier store assure feed water of high-performance technical grade single-chip microcomputer device, data are not lost and are guaranteed that water-feed can be competent at a job under various environment.
