Description

Wireless water level controller {WIRELESS TYPE LEVEL CONTROLLER}

The present invention relates to a wireless level controller, and to a wireless level controller for enabling a wireless operation of the existing wired method between the sensor (1) and the controller (6).

Conventional water level controller is a wired method between the sensor (1) and the controller (6) to construct the wiring of the sensor line (5) of the sensor (1) according to the function and buoyancy according to the water level of the water tank in the sensor (1) The lead S / W 11 embedded in the sensor pipe 2 is turned on by the float 4 to move the lead S / W 11 on by the magnet embedded in the float 4 to raise the water level. The sensing S / W 11 installed at different positions connects the ON signal to the input terminal of the controller 6 according to the position of the plot 4 to operate a transistor inside the controller 6 to drive a relay. By operating the magnet S / W in the pump control panel (7) with the contact output, the pump (8) was operated to automatically control the water level according to the level of the water tank. Let the output work.

However, in the existing method, the wiring of the sensor line 5 between the sensor 1 and the controller 6 is absolutely necessary, and when the function is added, the expansion of the wiring is inevitable.

The present invention does not require the wiring of the sensor line 5 between the sensor 1 and the controller 6 in a wireless manner at the position of the water tank of the water tank of the float 4 at the transmitter 13 of the sensor 1. Accordingly, when the lead S / W operates, the transmitter 13 transmits different frequencies in the sensor 1 and receives the frequencies at the receiver 12 so that the transistor in the receiver 12 operates and drives a relay to output a relay contact. It was connected to the sensor input terminal of the controller 6 to operate the controller to turn on / off the magnet S / W of the pump control only 7 so as to control the water level of the water tank wirelessly.

An object of the present invention is to install a transmitter 13 on the sensor 1 and to install a receiver 12 beside the controller 6 so that the existing wired water level controller can be wireless. It is a wireless water level regulator that can reduce construction cost and material cost by the method.

According to the present invention, the receiver 12 is installed next to the controller 6 of the water level controller, and the sensor 1 having the transmitter 13 embedded therein is installed on the upper part of the water tank, so that the wiring of the sensor line 5 is not performed. As to be able to automatically adjust the water level of the water tank as described below, based on the accompanying drawings of the present invention as follows.

FIG. 1 is a diagram in which a sensor line 5 is wired between a conventional sensor 1 and a controller 6 so that the water level of the water tank can be automatically adjusted. This suggests that wiring should be constructed between (6).

FIG. 2 shows that the transmitter 13 is installed inside the sensor 1 installed in the upper portion of the water tank without the need for constructing the wiring of the sensor line 5 in a wireless manner between the sensor 1 and the controller 6 of the present invention. When the built-in sensor 1 is installed and the lead S / W 11 is installed in the sensor pipe 2 according to the position, the float 4 moves up and down depending on the water level of the water tank. When the lead S / W is turned on by a magnet embedded in the inside to transmit a signal to the transmitter 13, the transmitter 13 transmits different frequencies, and the receiver 12 receives different frequencies, thereby receiving the inside of the receiver 12. Relay contact output is connected to controller 6, and contact output of controller 6 turns on / off the magnet S / W in pump control panel 7 to automatically adjust the water level in the water tank. It suggests that you can.

The position of the water tank detected by the lead S / W 11 in the sensor 1 is received from the input unit, and the PT2262 (6 outputs / frequency IC) is used to transmit a frequency band of 311 MHZ to the 6 outputs using the AM modulation method using the AM modulation method. The power supply unit has a built-in 9V battery to supply power to the transmitter (13) board module, and the frequency output unit outputs AM modulated frequency of 6 outputs according to the position detected by the sensor detector. In order to solve the problem of interference or malfunction when using more than one, set the address of PT2262 / IC input.
