Abstract

The utility model relates to a remote water-adding control device. The remote water-adding control device comprises a water level detection circuit and a single chip microcomputer control circuit; output signals of the water level detection circuit are transmitted to the single chip microcomputer control circuit through a Schmidt trigger circuit; and output signals of the single chip microcomputer control circuit are transmitted to an RS485 communication interface circuit and a water pump driving circuit respectively. According to the remote water-adding control device of the utility model, water level signals are acquired by the water level detection circuit; when a pool is in water shortage, through the identification and control of the single chip microcomputer control circuit, water shortage information is transmitted to a computer host machine console, such that remote control and monitoring can be realized, and a water pump can be protected from being damaged.

Description

A kind of long-range water controller that adds

Technical field

The utility model relates to a kind of control device, particularly be a kind of long-range water controller that adds.

Background technology

When the control water pumper draws water, if because of the pond lack of water, can cause water pumper to burn out because of long-time idle running.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of long-range water controller that adds is provided.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of long-range water controller that adds, comprise water level detection circuit and single chip machine controlling circuit, the output signal of described water level detection circuit transfers to single chip machine controlling circuit through schmidt trigger circuit, and the output signal of described single chip machine controlling circuit sends to RS485 communication interface circuit and water pumper driving circuit respectively.

Preferably, described water level detection circuit is made of the low water level sensor A and the high water level sensor B that are installed on respectively in the pond.

Preferably, described RS485 communication interface circuit is connected to computerized control system by SN75176 communication interface chip IC3.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: the utility model is gathered water level signal by water level detection circuit, when the lack of water of pond, after single chip machine controlling circuit identification control, reach the host computer control desk, realize Long-distance Control and monitoring, avoid damaging water pumper.

Description of drawings

Fig. 1 is frame assumption diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of long-range water controller that adds of the present utility model, comprise water level detection circuit 1 and single chip machine controlling circuit 2, the output signal of described water level detection circuit 1 transfers to single chip machine controlling circuit 2 through schmidt trigger circuit 11, and the output signal of described single chip machine controlling circuit 2 sends to RS485 communication interface circuit 21 and water pumper driving circuit 22 respectively.

Described water level detection circuit 1 is made of the low water level sensor A and the high water level sensor B that are installed on respectively in the pond, when water level when low water level sensor A is above, low water level sensor A is not unsettled, the 2nd pin of Schmidt trigger IC1 is greater than 1/3VCC, the 3rd pin output low level of Schmidt trigger IC1, P point journey low level state at this moment.When water level when low water level sensor A is following, low water level sensor A is in unsettled, the 2nd pin of Schmidt trigger IC1 is lower than 1/3VCC, the 3rd pin output high level of Schmidt trigger IC1, this signal is input to the 32nd pin I/O end of single-chip microcomputer IC2, after the identification of single-chip microcomputer IC2 internal processes, the 4th pin output trigger pip by single-chip microcomputer IC2, controllable silicon SCR is ended, the water pumper dead electricity, and can't work.Thereby play a protective role.

Another road output is by single-chip microcomputer IC2 the 10th, 11, the 1st of 25 pin and SN75176 communication interface chip IC3,2,3,4 form RS485 communication interface circuit 21, read Schmidt trigger IC1 data message by single-chip microcomputer IC2, after single-chip microcomputer IC2 internal processes judgment processing, send the driving command signal by single-chip microcomputer IC2 to SN75176 communication interface chip IC3, after SN75176 communication interface chip IC3 decoding, reach computerized control system by the warning bus, show current state information by control system, also can pass through operating system software, start and stop control to drawing water realizes Long-distance Control and monitoring.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
