[Industrial applications]

 The present invention relates to a water level detection control device for a type of water storage equipment, and is particularly used for large-scale water storage equipment, for example, water towers, water storage tanks, etc. to inform the user of the water storage status in the water storage equipment, and to control the pumping equipment at appropriate times. Then, it relates to the thing which replenishes water.

[0002]

[Prior art]

 Water storage facilities such as water towers and tanks are generally installed in modern buildings, but the purpose is to prevent the lack of water to be used. It is important that the amount of water is always maintained. It must be able to supply at least the amount of water required by the fire fighting equipment in an emergency.

In order to prevent the pollution of the stored water from the external environment, all the water storage facilities have a closed design, and the mounting position is usually the bottom or top layer of the building. For this reason, it is difficult for the user to know the water storage status at any time, and therefore the water cannot be replenished when the water is cut off, and the water storage may be exhausted. Normally, one water level switch is installed in the water storage facility, and at the same time the water level is lowered, the pumping equipment is driven to replenish the water.However, when the water is cut off, the pumping equipment cannot replenish the water either. You may find out that the water is exhausted for the first time.

【Example】

 1 and 2 are a circuit block diagram of the present invention and a partial circuit configuration diagram thereof. The water level detection circuit 10 detects different water level changes by a plurality of metal probes 100 extending to different depths in the water storage facility. The number of the metal probes 100 is the size of the water storage facility. The number of amplifiers 101 (AMP) is the same as that of the metal probe 100 in the water level detection circuit 10, and the equivalent circuit of each amplifier 101 is the same as that of the amplifier 101. The trigger signal is amplified by 101 to detect the water level change accurately, and the detection signal detected by the water level detection circuit 10 is sent to the filter circuit 11, which removes noise other than the trigger signal. Yes, the transmission circuit between the water level detection circuit 10 and the filter circuit 11 is wired in the building, but the degree of noise received affects the logic judgment of the circuit. Therefore, it is necessary to install this filter circuit 11. The signals output from the filter circuit 11 enter the switch control circuit 12 and the encoding circuit 14, respectively, of which the switch control circuit 12 is controlled by the above-mentioned detection signal and also has one logic judging device. 121 preferentially drive the motor 13 by the manual switch SW-1 to drive the pump to draw water, or forcibly close the other switch SW-2 to stop the operation of the motor 13. Thus, the present proposal has the characteristics of manual and automatic detection control. In addition, the control of stopping the motor 13 has priority over the control of driving the motor 13 to prevent the motor 13 from idling and burning due to water extraction under a water shortage condition or a special condition. Since the DC stable voltage supply circuit 102 in the circuit and the general power supply are the same and well known to those skilled in the art, detailed description thereof will be omitted here.

Subsequently, as shown in FIGS. 1 and 3, the plurality of detection signals described above are converted into 4-bit signals by the encoding circuit 14 and sent to each user. The encoding circuit 14 also receives one buzzer and a control signal output from the display control circuit 15. The buzzer and display control circuit 15 charges the time control IC 4541 (U8, U9, U10), capacitors (C1, C2, C3), and variable resistors (VR-1, VR-2, VR-3). And the discharge time control enables the replacement operation between the display and the buzzer 17, 17 '(shown in FIG. 4) to be adjusted in a timely manner. Among them, the time control IC (U8) is the display 1 The flash cycle of 71 is controlled (FIG. 4), and the other IC (U9) controls the buzzer time of the buzzer 172. As a matter of course, the replacement time of the buzzer 172 and the display 172 described above is controlled by the IC (U10). However, the operation status of the buzzer and the indicator control circuit 15 is such that when the water level of the water storage facility falls to a warning state, any one output of the amplifier (AMP-4, AMP-9) (FIG. 2) is output. The signal to activate immediately activates the display 171 and the buzzer 172 (FIG. 4).

Further, as shown in FIGS. 1 and 4, the 4-bit signal output from the above-described encoding circuit 14 is sent to each home via the bus 130 (BUS), and each home receives one decoding time. Channels 16, 16 'and associated indicators and buzzers 17, 17' are provided, and the indicators 171 are composed of light emitting diode LEDs in the same number as the metal probes 100 (FIG. 7) described above. To be done. The purpose of adopting the technical means of encoding and decoding in the circuit of the present invention is to reduce unnecessary waste of cost by achieving an equivalent signal output by transmission of the minimum bit. The working method of the circuit of the present invention is achieved by other equivalent circuits, and therefore, changes made by those skilled in the art to achieve the same purpose are also included in the technical scope of the present invention.
