S) or when the program logic controller 24 and the inverter 21 of the well control device 10 are transmitted to the portable terminal of the manager and operated according to the data transmitted from the central server S and the portable terminal of the manager. Reactor 21a replacing the inverter 21, a filter f for filtering noise generated from the well control device 10, a temperature sensing device t for sensing the temperature of the well control device, and an inverter- Reactor selector switch (sw) and uninterruptible power supply ( ups) the control unit, the program control controller 10 of the control unit 20, the abnormal situation data and the operation status data of the well control device 10, groundwater motor (1), water tank (3), chemical tank (6) Received from (24) and transmitted to the central server (S) and the portable terminal of the manager, receiving control data in the form of text data transmitted from the central server (S) or the portable terminal of the administrator, the program of the control unit 20 CDMA which performs bidirectional communication to transmit to the logic controller 24 so that the program logic controller 24 of the controller 20 executes control data in the form of text data transmitted from the central server S and the manager's portable terminal.

On the other hand, the data transmission and reception method of the central server 1 and the CDMA communication device 30 is a CDMA (Code Division Multiple Access) method, so that the user transmits and receives signals while sharing time and frequency. It is a kind of multiple access method using spread-spectrum technology, which has more than 10 times the capacity and excellent call quality than the analog method (AMPS).

In addition, spread-band communication refers to spreading and spreading a signal with a bandwidth wider than that of a signal to be transmitted. Since the signal has a low power density, it is difficult to detect the presence of a signal, and the receiver despreads the received signal. In order to generate the original signal in the process, it is necessary to know the code used at the time of spreading, so the confidentiality of the communication is guaranteed, and the external disturbance signal is spread in the reverse process, so it does not disturb the communication.

Hereinafter will be described the most preferred embodiment of the present invention.

First, the groundwater motor (1), the water tank (3), the chemical tank (6), the well control unit 10 and the control unit 20 formed in the well control unit 10, the CDMA communication device 30 and the center Configure the system by installing the server (S).

Here, it is obvious to operate by applying power to the well control device 10 or the like.

In addition, the control unit 20 of the well control device 10 further includes an uninterruptible power supply (ups), so that the uninterruptible power supply (ups) even if the power applied to the well control device 10 is cut off. Emergency power is applied.

Then, while the program logic controller 24 of the well control device 10 is operated, the inverter 21 is operated so that the inverter 21 slowly applies current to the groundwater motor 1 installed underground and increases the current. Let's do it.

Here, it is obvious that the program logic controller 24 formed in the controller 20 of the control controller 10 controls the devices (inverter, monitor, insulation resistance meter, etc.) installed in the controller 20 as a whole.

Thereafter, while the groundwater motor 1 to which the current is applied from the inverter 21 is slowly operated (it rotates at 1500 to 1600 rpm per minute), the groundwater is stored in the water tank 3 while raising the groundwater, and at the same time, the chemical tank In (6) the medicine is injected into the water tank (3) by the operation of the chemical pump (5).

Here, it is obvious that the chemical residual sensor 4 formed in the chemical tank 6 detects the residual amount of chemical injected into the water tank 3 from the chemical tank 6.

In addition, the chemical tank (6) formed with the water tank (3), the chemical residual amount sensor (4), and the chemical pump (5) in which the groundwater motor (1) and the water level sensor (2) are installed in the well control device (10). And it is obvious that the control unit 20 and the CDMA communication device 30 is connected in a wired or wireless form.

In addition, the well control device 10 is provided with an output terminal (not shown), a magnetic contactor (not shown), the groundwater motor 1 and the chemical pump 5 start, stop, manual switch It is obvious.

When the water level sensor 2 installed in the water tank 3 measures the water level of the groundwater stored in the water tank 3 and reaches a predetermined water level designated by the manager, the program logic controller 24 switches the inverter 21. By operating the groundwater motor 1 by gradually reducing the current applied to the groundwater motor (1) while stopping the operation of the groundwater motor (1).

Meanwhile, as described above, the groundwater motor 1 is operated, the groundwater is stored in the water tank 3, and the data generated while the chemical tank 6 is operated is transmitted to the central server S through the CDMA communication device 30. At the same time, it is obvious that the central server (S) stores the data transmitted from the well control device 10 and is controlled by the administrator.

In addition, it is obvious that the well control device 10 and the central server S are connected by a commonly used Internet or code division multiple access method.

As described above, the inverter 21 controlling the operation of the groundwater motor 1 is configured to slowly apply and remove the current applied to and removed from the groundwater motor 1 so that the current is not applied to the groundwater motor 1 at once. Minimizes the maneuvering shock transmitted to the groundwater motor (1) to protect the groundwater motor (1), as well as to control the rotational speed of the groundwater motor (1) to reduce the energy applied to the groundwater motor (1) do.

In addition, even if the inverter 21 controlling the groundwater motor 1 is damaged, a reactor 21a is formed in place of the inverter 21, so that the groundwater motor 1 can be secondarily controlled.

When the inverter 21 is damaged, the inverter-reactor selecting switch sw formed in the well control device 10 is automatically rotated in the reactor direction so that the reactor 21a controls the groundwater motor 1. .

Then, after the manager replaces the damaged inverter 21, the inverter-reactor selector switch sw rotated in the reactor direction is rotated in the inverter direction so that the inverter 21 controls the groundwater motor 1.

In addition, the program logic controller 24 of the well control device 10 is a groundwater level stored in the water tank 3 by the groundwater motor 1 and the well control device 10 and the groundwater motor 1, water The operating state of the tank 3, the chemical tank (6) is controlled.

In addition, the control unit 20 further includes a filter (f) to remove the noise generated in the data transmitted from the well control device 10 to the central server (S) to transmit higher quality data, A temperature sensing device (t) for detecting the temperature of the well control device 10 is further included, so that the heat generated in the well control device 10 is sensed so that the well control device 10 is overheated and broken or malfunctions. To prevent it.

On the other hand, when the abnormal situation occurs in the groundwater motor 1, the water tank 3, the chemical tank 6, as shown in Figure 2a, the control unit installed in the well control device 10 The program logic controller 24 of 20 transmits the abnormal situation data in which the name and the current state of the device in which the abnormal situation occurred are stored to the portable terminal of the central server S and the manager via the CDMA communication device 30.

Then, if the administrator is located in the central server (S), it generates the control data through the central server (S) and the central control system via the central control unit (S) and the CDMA communication device 30 installed in the central server (S) It transmits to the program logic controller 24 through the CDMA communication device 30 installed in (10).

Then, the program logic controller 24 installed in the well control device 10 analyzes the control data transmitted from the administrator to control the device.

Here, as shown in b to 3 of FIG. 2, even if the administrator is not located in the central server (S), after confirming the abnormal situation data transmitted to the portable terminal of the administrator, control data suitable for the abnormal situation data is character data The program logic controller 24 controls the device by transmitting the program logic controller 24 to the program logic controller 24 through the CDMA communication device 30 of the well control device 10.

Therefore, even if the administrator does not always reside in the central server S as described above, the administrator can check the malfunction of the control device 10 at any place, the administrator does not reside in the central server (S) and other tasks It can run in parallel, reducing manpower costs and increasing work efficiency.

After the administrator confirms the abnormal situation data transmitted to the central server (S) or the manager's portable terminal as described above, the administrator can set the control device 10 and the groundwater motor 1 at a remote location through the administrator's portable terminal. Or change the management data stored previously.

On the other hand, if an abnormal situation occurs in the groundwater motor 1 among the abnormal situation data transmitted to the portable terminal of the administrator or the central server (S), the insulation resistance meter (23) to the control unit 20 of the well control device (10) Is formed, and the insulation resistance value of the groundwater motor 1 is measured to accurately determine the failure state of the groundwater motor 1 (whether it is simply stopped or not, whether the groundwater motor is damaged, etc.) and transmit it to the manager.

Then, the administrator checks the abnormal situation data transmitted to the central server (S) or the portable terminal, and when the groundwater motor (1) is simply stopped, the groundwater motor (1) through the central server (S) or the portable terminal of the administrator To restart the operation of the groundwater motor (1), if the abnormal situation of damage to the groundwater motor (1) installed in the manager to move to replace the groundwater motor (1).

Here, generally, the groundwater motor 1 is simply notified to the manager of the groundwater motor 1, and the groundwater motor 1 is installed in the depth of the ground. It is costly to raise.

Therefore, it is necessary to accurately check whether the groundwater motor 1 is replaced and set only when the operating state and the failure state of the groundwater motor 1 are accurately identified as described above.

Then, when the manager moves to the place where the groundwater motor 1 is installed in order to check the damage of the groundwater motor 1 and replace the groundwater motor 1, the manager 20 is installed in the control unit 20 of the well control device 10. By using the monitor 22, it is possible to easily check the current state of the equipment installed in the control unit 20 of the well control device 10, as well as the current state of the groundwater motor (1).

On the other hand, as described above, whether the groundwater motor (1), the water tank (3), the chemical tank (6) and the well control device 10 is broken, even if the administrator does not reside in the central server (S), the administrator's mobile terminal at a remote location The control data according to the failure can be transmitted through the administrator's portable terminal, preventing the user's inconvenience due to the groundwater pipe monitoring and the failure of the remote control system and preventing the groundwater pipe monitoring and the remote control system. The manager does not have to reside in the central server (S) to reduce the waste of manpower and manpower costs.
