Abstract

In case of farming fish and shellfish by attracting seawater from the offshore sea In case of malfunction such as supply pump malfunction, power failure, or conduit closing, there is always a risk of damage to the pump, death of fish and shellfish etc. Knowing that the pump will continue to operate until the power is turned off, the damage is inevitable.

In this paper, self-diagnosis can be automatically and automatically performed through relay using seawater pump, vacuum pump and automatic valve by using PLC and computer, so that the seawater pump stops no-load rotation immediately when it malfunctions or stops operation and charges by vacuum pump operation. After the water was filled, it was operated. When the valve was completely destroyed, it was possible to continue to supply seawater with a separate manual valve. In addition, the workers who are remotely informed of the failure status of the pump by a pager, telephone, alarm, etc., and at the same time self-diagnosing the problem that can be caused by running the pump.

Description

Automatic operation alarm system of fish farm feed pump

The present invention relates to an automatic operation and alarm system of a fish farm supply pump that enables idling monitoring, idling prevention, automatic operation and alarm of a feed pump in a fish farm using seawater.

In the case of farming various fishes using seawater, in order to continuously supply fresh seawater, conduits are extended to nearby seas, and the seawater is pumped from this place. The most important function of such seawater supply is the pumps, which can stop normal seawater supply due to unexpected power outages, conduit closures or other failures. In case of a momentary power failure, the pump operates as it is, so damage is inevitable, and it is also a great waste of manpower because it is always waiting for personnel to be immediately released to solve such conditions. In particular, if airborne personnel are located remotely, even if such a situation is detected, it is not immediately possible to deal with mechanical damage and loss of fish and shellfish.

The present invention uses PLC (Programmable Logic Controller) and single board computer as basic controllers, but it connects supply conduits, vacuum pumps, valves, etc. to the aquaculture tank with electronic relays. In case of emergency, all the matters can be directly reported to the administrator. Therefore, it is possible to prevent the risk of damage to the pump or the death of farmed fish that may occur during absence, as well as to prevent damage due to no-load rotation of the pump.

The present invention is in aquaculture tank system for aquaculture of fish and shellfish by continuously supplying in a tank of a certain standard through a water intake pipe in the offshore sea,

These pumps and valves are connected to a PLC and an electrical signal-connected relay, and the PLC is configured to be connected to a single board computer while the alarm and telephone lines are connected to the PLC and the single board computer. It is configured to connect to.

In the present invention, a single board computer can be used as long as it has a read only memory (ROM), a CPU (central processing unit), an interface, a memory, an input device, and an output device, and a general IBM-based PC can be used.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the overall configuration of the present invention, Figure 2 is a schematic diagram of the operation by the program embedded in these devices.

The present invention is a structure to connect the conduit between the vacuum pump (1) and the sea water pump (1) (2) and 2 (3) via a manual valve and an automatic valve,

The electronic control valve of the seawater pump 1 (2) is a relay 1 (6) and the first automatic valve (7) adjacent to the seawater pump 1 (2) is connected to the relay 2 (8), the vacuum pump (1) The second automatic valve 9 in the conduit is relay 3 (10) and the third automatic valve 11 adjacent to the sea water pump 2 (3) is the solenoid valve of the relay 4 (12) and the sea water pump 2 (3). Is configured to be connected to relay 5 (13), but each relay is connected to the PLC (15) and the electrical signal,

The PLC 15 is connected to the signal line 16 and the seawater pump operation detection signal line 17 of the general electric line and the generator electric line to the input side and the external alarm 18 to the output side,

The single board computer 20 connected to the electric signal to control the PLC is connected to the PLC bidirectional communication signal while the input side is connected in parallel with the signal line of the input side of the PLC and the output side is an alarm or pager of the remote home 100 (50) and wired and wireless connection.

In the present design, relay 1 (6) and relay 5 (13) are connected to the output terminal and the other relay is configured to connect the input terminal.

In the present invention, the first automatic valve 7 is disposed between the two manual valves 21 and 22 of the conduit 1 19, and these manual valves are bypass conduits 1 23 with the manual valve 24 disposed therein. Are all comprehensively composed of

The third automatic valve 11 is also arranged between the two manual valves 26 and 27 of the conduit 2 25 and is entirely encompassed by the bypass conduit 28 with another manual valve 28 '. It is. Similarly, the second automatic valve 9 is disposed between two manual valves on one side of the vacuum pump 1 and is configured to cover them with another bypass conduit.

The operational relationship according to the above structural features will be described.

In general, the seawater pumps 1 and 2 (2) (3) are filled with seawater in the pump by the operation of the vacuum pump 1 at the initial operation, and then the operation starts. Therefore, the sensor connected to the general electric line and the generator electric line 15 detects the normal operation of electricity or the normal operation of the generator and transmits the signal to the PLC 15 and the single board computer 20. Otherwise, it determines whether it is in an abnormal state and emits a signal to an alarm with a manager in case of abnormality, or operates a generator, and emits seawater operation signal in normal operation, and detects whether or not idling occurs when the seawater pump operates. When the signal is transmitted to the single board computer 20, when it is determined that it is abnormal, it sends an electric insulation signal to the seawater pump and supplies a working signal of the vacuum pump 1 after a predetermined time to operate the vacuum pump for a predetermined time. It turns off again and supplies a signal to turn on the seawater pump again after a certain time relay, and at the same time, a certain amount of time is applied to the pager and alarm signal line. A wired and wireless signals, and ever supplied, during normal operation advances to the steps of the signals from the various sensors of the seawater pump is constituted by a step which continues the scanning.

In the present invention, the automatic valves (7), (9), and (11) close the manual valves (21), (22), (26), and (27) on both sides thereof in case of a failure, respectively, 23) and (28) so that the seawater supply is not interrupted.

The present invention is designed to first monitor the normal supply of electricity through the sensor and to operate the generator in case of abnormality. It is now possible to prevent damage to the pump due to numerous load-free rotations. In addition, all these abnormal conditions are transmitted to the remote manager by an alarm or telephone line, so that immediate response is possible anywhere. In addition, these operating rules can be modified at any time by the flexibility of the program, and can be automatically adjusted to various environmental changes.
