The specific embodiment
Embodiment 1, and present embodiment is a kind of water tower intelligence water level controller, and this controller can be according to the height automatic water supplement of water level in the water tower.As shown in Figure 1, a kind of intelligent Level Control of Water Towers device comprises the water pump to water tower water-feeding, and the ball float of control water level and the float switch of water inlet are set in water tower; The control circuit of control of pump machine operation is characterized in that: described control circuit comprises processor, is arranged on the relay in the described pump motor current supply circuit, and described relay connects described processor; Pressure sensor also is set; Described pressure sensor comprises the biography magnetic conductive pole that is arranged on the dependence gravity clutch in the water pump water outlet pipeline, and with the adaptive magnetic reed switch of described biography magnetic conductive pole, described magnetic reed switch is linked into described processor.
As shown in Figures 2 and 3, pass magnetic conductive pole and comprise trip(ping) lever 1 and inner magnetic core 2, be sealed in the water pump water outlet pipeline by leather packing 3.Magnetic core 2 triggers magnetic reed switch.
In the present embodiment: as shown in Figure 4; The drive circuit of processor control relay comprises the NPN triode Q1 that is arranged between described relay and the ground; Its model is 9013; The colelctor electrode of triode connects power supply through described relay coil, the grounded emitter of triode, and the base stage of triode connects the control signal output of processor.Between processor control signal output and triode Q1 base stage, also be connected with current-limiting resistance R3; Polyphone ground resistance R5 between processor control signal output and ground; Anti-phase inserts diode D1 between the colelctor electrode of 12V power supply and triode Q1, and its model is IN4007.On processor circuit, also be provided with delay circuit and the circuit that delay time is set, be used to be provided with number when handling, through processor is provided with time-delay; To the time time, the control relay adhesive, pump motor meets the electrician and does; In water tower, supply water, when water in the water tower completely arrived certain altitude, ball float drove the ball type switch outlet conduit that switches off the pump; Hydraulic pressure in the water pump water outlet pipeline is raise, and magnetic reed switch is closed, gives signal of processor; The processor control relay is removed adhesive, and the pump motor outage finishes to supply water.
