Abstract

The utility model relates to an intelligent control device for a waterworks. The intelligent control device comprises a water pipe current detection circuit and a keyboard operation circuit, wherein the water pipe current detection circuit is formed by the output connection of the metal bars (A and B) mounted in a water pumping pipe with resistors (R1 and R2); the output signal of the water pipe current detection circuit is transmitted to a singlechip (IC1), is connected with a relay (J1) through the output level signal of singlechip (IC1) by passing through a triode (VT1), and controls a water pumping motor (M) through a normally closed switch (J-1); the keyboard operation circuit is formed by connecting in series a resistor (R3) with keys (K1,K2 and K3) respectively; and the keyboard operation circuit transmits data command to the singlechip (IC1). The device adopts the water pipe current detection circuit, and the keyboard operation circuit is used for controlling the water pumping motor to operate or stop; when no current flows in the water pumping pipe of the water pumping motor, the singlechip controls the output drive GSM module to transmit the present working condition of the water pumping motor, so as to achieve the purposes of protecting and monitoring the intelligent management of the water pumping motor, and avoid the inconveniences brought to the daily production and living of human being as caused by the failure of the water pumping motor.

Description

The waterworks intelligence controlling device

Technical field

The utility model relates to a kind of waterworks intelligence controlling device.

Background technique

Tap water brings great convenience for people's productive life, but the waterworks when drawing water because drought river water level when descending, the suction engine drinking-water pipe is not inhaled water, and suction engine can serious heating finally cause suction engine to burn out, and brings great inconvenience for people's production and life.

The model utility content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of waterworks intelligence controlling device of monitoring and protection suction engine is provided.

The technological scheme that the utility model adopted is such: the waterworks intelligence controlling device, comprise water pipe current testing circuit and keyboard operation circuit, described water pipe current testing circuit is made up of metal bar A, the B output connection resistance R 1, the R2 that are installed in the drinking-water pipe, its output signal sends to single-chip microcomputer IC1, outputs level signals by single-chip microcomputer IC1 connects relay J 1 through triode VT1, controls the motor M that draws water by normally closed switch J-1.

Described keyboard operation circuit is made up of connect respectively button K1, K2, K3 of resistance R 3, the keyboard operation circuit sends data command to single-chip microcomputer IC1, the time of clock chip IC2 is set by single-chip microcomputer IC1, and form serial communication circuit by single-chip microcomputer IC1 and storage chip IC3, data information is deposited into the ROM database, when time command is consistent in the ROM data of clock chip IC 2 and storage chip IC3, drive the motor M operation or stop of drawing water by Single-chip Controlling.

Described single-chip microcomputer IC1 output connects LCD display circuit IC4.

Described single-chip microcomputer IC1 and the transmission of GSM short message receiving-transmitting IC circuit 5 two-way signalings.

By adopting the aforementioned techniques scheme; the beneficial effects of the utility model are: this device adopts water pipe current testing circuit; by draw water motor operation or stop of keyboard operation circuit control; when the drinking-water pipe of suction engine does not have flowing water; drive the working state that gsm module sends current suction engine by Single-chip Controlling output; thereby reach the purpose of protection and monitoring suction engine intelligent menagement, avoid giving people's production and the inconvenience that life brings because of the suction engine fault.

Description of drawings

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the waterworks intelligence controlling device, comprise water pipe current testing circuit and keyboard operation circuit, described water pipe current testing circuit is made up of metal bar A, the B output connection resistance R 1, the R2 that are installed in the drinking-water pipe, its output signal sends to single-chip microcomputer IC1, when suction engine draws water, outlet pipe has current to pass through between metal bar A, the B point, supply voltage by the water electric conductor through resistance R 2, R1 dividing potential drop over the ground, defeated eight to single-chip microcomputer IC1 the 25th pin I/O end is high level, illustrate that drinking-water pipe has current to pass through, represent working properly.When not having water between metal bar A, the B of drinking-water pipe; make metal bar A be in vacant state, supply voltage is without the water electric conductor, and the 25th pin I/O of single-chip microcomputer IC1 end is low level; control through single-chip microcomputer IC1 internal processes; the 4th pin output low level from single-chip microcomputer IC1 ends triode VT1 through resistance R 4 current limlitings, and relay J 1 discharges; normal open switch J1-1 transfers normal battle to; the motor M that draws water does not have power supply, stops pumping, and the protection electric pump is avoided lack of water and burnt out.

Described keyboard operation circuit is by the resistance R 3 button K1 that connects respectively, K2, K3 forms, when pushing button K1, single-chip microcomputer IC1 is to DC1302 clock chip IC2 transmitting time modify instruction, show the current time, by the K2 that pushes button, K3 revise to be provided with the motor M operation or stop of drawing water, read the DC1302 clock chip IC2 current time through the internal processes judgement by single-chip microcomputer IC1, by the 5th of single-chip microcomputer IC1, the 5th of 7 ends and 24C02 storage chip IC3,6 ends are formed serial communication circuit, data information is deposited into the ROM database, read the current time of DC1302 clock chip IC2 as single-chip microcomputer IC1, when consistent with time command in the ROM data of 24C02 storage chip IC3, control through single-chip microcomputer IC1 internal processes, the level of exporting from the 4th pin of single-chip microcomputer IC1 is connected to triode VT1 through R4, output to relay J 1 again, draw water motor M operation or stop of normally closed switch J-1 control.
