And the microcomputer 1 (7) for judging the situation, the communication unit (8, 9) of RS485 for transmitting data, the voice storage (14) for sending up, and the telephone transmitter (16) for delivering upbringing voice and real time. It relates to a real-time checker 20 for checking and the current notification and failure signal notification siren 19 in conjunction with the site and acts in conjunction with the current sensor using a quantity detection method.

Description

{A water amount checking method using an ammeter sensor with calling service}

According to the present invention, the motor is operating normally because water is blocked at the end of the inlet of the end pipe having one fish per shell or seaweed on the end pipe side of the plurality of pumping motors that operate 24 hours in a fish farm that raises meat at the beach. In many cases, the volume is significantly reduced, which is a way of notifying in advance that the tank is draining water.

In the prior art, a method of using two electrode rods as a sensor of a fish tank and a method of ringing a bell with a sensing sensor of an electrode when water drops. Therefore, even when the water pump motor electronic switch is opened due to a momentary power failure, the water is not only detected after the tank is drained, but even if one or two of the water pump motors are opened, it cannot be identified in advance. The staff at the farm should be nervous at all times, especially due to the momentary power outage and blockage of the water intake due to the salt content of the fragile cables at night. At the same time, although the sensing rod is used, it is very inconvenient if the substance is caught in two sensing rods in the flowing water.

In particular, the distance between the office and the pumping station is usually 300 meters, so if you do not pay attention to the situation can not stop the death of meat.

In order to solve the problems described above, the amount of water pumped by the pump motor is applied in a linear proportion to the amount of current used as a power source. If the quantity of water is Q, the wastewater is trapped in the pump motor end pipe and if the water rises small, it becomes Q- △. This formula is A- △ when the quantity of water Q is the amount of current A. At this time, △ amount of current is detected by the amplifier and operated as hardware and software, and the data is sent to the office that manages the cattle farm by RS485 communication, and the main unit calls the call function, breeding notification function, real-time breeding notification function, siren output function, Implemented to have phase-out and power outage notification.

In other words, the amount of water to be pumped to the water tank is proportional to current, so it does not detect overcurrent but detects current with a large amount of water at the rated current and operates it with hardware and software to adopt RS485 communication to the remote farm office. The technical task of the present invention was to transmit the data to the unit so that the result of judging the quantity is output by voice and a call to a mobile phone, and the set function such as a real time notification function can be performed.

A / D converter (6) by amplifying the input of the three-phase voltage detection PT (1), the small current detection CT (2), and the image current transformer (3) installed in the pump house of the pump house to an appropriate value as the amplifier (4). Supplies). As a soft control of the microcomputer 1 (7), the digital conversion value is read and stored in the buffer embedded in the microcomputer 1, and the stored value is stored in the microcomputer 2 (remotely located at a long distance by RS485 communication using the communication unit 8,9 of the RS485 method. 10) The data is transmitted.

The microcomputer 2 10 compares and analyzes the user's set values with various data transmitted and stores them in an external memory and expresses the values on the display 12 so that the user can understand them. If the user is out of the set value and immediately call the digitized voice memory of the voice storage unit 14 and the speaker 15 through the voice converter (13). After completion of the notification, the microcomputer 2 10 accesses the telephone communication line through the phone transmitter 16 under the control of the microcomputer 2 10 and calls the mobile phone terminal of the user while the microcomputer 2 10 switches the voice converter 13 and the speaker 15. Control and carry out nurturing notifications.

After notifying the user by nurturing, the microcomputer 2 (10) controls the relay 18 to operate the siren 19 to inform the staff managing the farm.

On the other hand, if the user's terminal is busy or using a communication line telephone to transmit, wait for a while and then repeat the programming to perform the dialing function.

In more detail with reference to Figure 2,

The user inputs a user set value of the set value storage unit 11, a telephone number to be transmitted, a real time input, a voice message output time input, an appropriate value for obtaining a fault signal, and the like as a key.

The microcomputer 1 (7) for soft control initializes the input / output data, reads the input data such as voltage, current, and leakage current, and transmits them after A / D conversion.

If the received data is more than the user's set value, it is determined as a failure and stored in the temporary storage and displayed on the display 12. Compare again to see if it is a fault and return if it is not a fault. However, if a failure signal is received, the voice is sent first, then the user dials the phone number previously input, and when the phone is connected, the voice message entered in the memory is sent out and the voice is transmitted. At the same time, the microcomputer 2 10 operates the relay 18 to drive the siren 19.

In addition, if the user inputs a specific time in the microcomputer 2 (10) so that the user can be notified at a specific time, such as feeding time to the nursery, the microcomputer 2 (10) compares the real time and the input time of the user to match When the voice address is input to the voice storage unit 14, the voice address can be sent to the speaker and notified to the user.

The present invention as described above, by completely removing the various unnecessary points of the water detection method to detect and confirm with the existing electrode rod, can be found by the manager before the water of the tank falls, the moment of power failure of the motor electronic switch It distinguishes which motor is within a few seconds, so it can be reloaded without embarrassment in the machine room, and it is not necessary to check the machine room remotely from the office at night. It is not necessary to replace the sensing rod. In particular, at night, foreign substances are entangled in the sensing rods, causing the fish tanks to lose hundreds of millions of dollars in property due to inability to detect them. Indeed, it is a great invention that can be of great help.
