Description

System for monitoring and controlling electric distribution panel board in remotely}

The present invention relates to a remote monitoring and control system of a distribution panel, and to monitor and control the distribution panel operation panel attached to a local control panel for each distribution panel in a branch circuit unit, and supply power sequentially with a certain delay time according to the output signal of the user. In order to prevent the risk of power transmission due to a wrong mode selection, the present invention relates to a distribution panel remote monitoring and control system configured to efficiently and safely monitor and control the distribution panel by remote two-way communication by configuring a magnetic control switch unit.

With the increase in the number and size of buildings, power facilities are increasing, and power equipment for precision control is increasing due to the high-tech industrialization. Accordingly, the necessity of monitoring and controlling the power supply status of each area and various power equipments is also highlighted. However, the conventional technology monitors and controls the power of the switchboard and the distribution boards and not the trunk and branch circuits. Not only can't control magnetic switch independently, but also large power (150kV-380kV) is supplied at every unit distribution panel, which has the risk of burnout and fire, and enormous expenditure and space for construction cost due to wiring work. Maintenance and repair are not easy due to the difficulty of working environment, the risk of safety accidents, malfunction of manual operation of the operator, and difficulty of understanding the state of power.In particular, when using midnight power, the user controls the branch circuit to the breaker in the field. There is a problem that can only reduce the waste of power.

1 is a schematic view showing the configuration of a conventional magnetic operation panel.

Referring to FIG. 1, in the conventional switchboard, the user operates the pressure switch in a one-to-one correspondence with the magnetic switch of the individual distribution board in a sleeping room or a sitting room. In addition, a large power supply (150kV-380kV) is supplied in unit board units.

In the conventional distribution panel configured as described above, a power line is connected to the magnetic switch of the distribution panel from the operation panel of the job room. As a result, a considerable amount of power line is required for the wiring work, and the construction cost burden and accident risks are involved. In addition, due to the large power supply, there is a high possibility of an electrical accident, such as sparking when the magnetic switch of the distribution panel is operated.

In addition, there is no protection circuit that can cut off power supply due to user's mistake, and there is no recovery measure in case of power failure of branch circuit and trunk because user cannot grasp the power status, and experts also have to check all power lines. There was a difficulty in maintenance.

In such a conventional device, there is no way to recognize and prevent the risk of power transmission due to a faulty operation of a selection switch and grasping a distribution state by manually operating a pressure switch on a control panel of a desired power line.

In addition, by simultaneously transmitting dozens of switchboard magnetic switches in the switchboard, there is a risk of burnout and fire caused by deterioration and overload in the magnetic switch, and there is a problem of enormous expense of construction costs in a one-to-one manner.

The present invention has been made to solve such a conventional problem, by selecting and managing a distribution line to supply power conveniently at a user's desired place to eliminate the waste of power and the occurrence of electrical accidents, risk of construction and The purpose is to provide a safe and efficient distribution panel remote monitoring and control system by reducing the construction cost.

The generator 170 and the communication unit 180 for transmitting the control signal of the microcomputer for the local monitoring control panel or the magnetic switch selected by the user to the local monitoring control panel of each distribution panel equipped with the selected local monitoring control panel or the magnetic switch. It consists of.

The touch screen type key switch unit 120 is used to input a control command for each magnetic switch unit or panel unit to supply power to the branch circuit of the distribution panel to be controlled by the user.

Specifying up to eight branch circuits per magnetic switch unit, if a central monitoring control unit implements individual control for up to eight magnetic switch units and individual control for up to sixteen switch unit units. Eight keys are provided and 16 keys are designated to designate up to 16 units per unit board. However, the number of the provided keys is not necessarily limited thereto.

The distribution panel selection control switch unit 140 sets a user's use of the local monitoring control panel or the magnetic switch of the distribution panel to be used by the user in advance, thereby providing a power control function that can prevent power supply due to a user's selection mistake. Will be performed.

The microcomputer 150 processes a power supply and a state according to a user's selection, performs sequential control of the power supply, and executes a program for storing and integrated management of all input power data. By operating the magnetic switch with a predetermined delay time when the microcomputer 150 supplies power to each switchboard magnetic switch, it is caused by deterioration and overload of the magnetic switch, which is caused by power transmission for several dozens at the same time. It can prevent the risk of burning and fire.

The communication unit 180 monitors and controls the state of the branch circuit, and communicates the input signal of the individual power state of the branch circuit sent from the distribution board local monitoring and control panel 200 to provide an alarm when an abnormality occurs in the power line and load. Perform.

The operation of the distribution panel central monitoring and control panel configured as described above is as follows. First, when a user inputs a signal through a touch screen 120 or a remote controller (receive demodulator) 130 to a power distribution panel and a magnetic switch of a power line, the input signal is input to the liquid crystal display 110 by the microcomputer 150. Appears at), by using the RS 422 communication method selectively by the microcomputer 150 can transmit power to the local monitoring control panel 200 of the distribution board for each zone to supply power to a desired place.

In addition, the microcomputer 150 supplies power with a delay time of several seconds in the magnetic unit at the time of power supply, thereby preventing the occurrence of fire due to the failure of the magnetic switch and sparks, and By outputting the abnormal state to the liquid crystal display through the microcomputer, the user can quickly and conveniently monitor and control the state of power.

In addition, since the switchboard selection control switch unit 140 for power control is provided, it is recognized by the microcomputer when the selection switch is opened according to the intended use, and the power supply is cut off even when the user selects a power line by mistake. It is possible to prevent the loss of power by cutting off the power supply in unnecessary places.

The distribution panel selection control switch unit 140 may be largely composed of two parts. First, the magnetic switch selection switch unit for the operation control of the magnetic switch unit, and the distribution panel selection switch unit for the operation control of the distribution panel unit. The switchboard selection control switch may be implemented in various forms, but an embodiment using the dip switch will be described.

A 3-pole dip switch is used for the magnetic switch selector switch, and a 5-pole dip switch is used for the local supervisory control panel selector switch.

First, the 3-pole dip switch provided to set the use of each magnetic switch can have a maximum range of 8 magnetic switches to be used by the combination of the respective poles.

That is, as shown in Table 1, each pole can be set on or off.

<Table 1. Magnetic Switch Selection Control Switch (3 Pole)>

One 2 3 Number of use One ON ON ON 1EA 2 OFF ON ON 2EA 3 ON OFF ON 3EA 4 OFF OFF ON 4EA 5 ON ON OFF 5EA 6 OFF ON OFF 6EA 7 ON OFF OFF 7EA 8 OFF OFF OFF 8EA

If the first pole is turned off and the other two poles are turned on, as shown in Table 1, up to two magnetic switches can be used, and the first magnetic switch and the second magnetic switch among the magnetic switches provided in the distribution board are provided. This is the case when the magnetic switch is set to use.

On the other hand, when the first pole is turned on and the other two poles are turned off, this means that up to seven magnetic switches can be used, which means that the first magnetic switch to the seventh magnetic switch can be used.

In addition, the 5-pole dip switch provided for setting the use of each distribution board can have a maximum of 16 selection ranges for the distribution board to be used by the combination of the respective poles. That is, as shown in Table 2, each pole can be set on or off.

<Table 2. Distribution switch selection control unit to be used. (5 Pole) ＞

One 2 3 4 5 Number of use One OFF ON ON ON ON 1EA 2 ON OFF ON ON ON 2EA 3 OFF OFF ON ON ON 3EA 4 ON ON OFF ON ON 4EA 5 OFF ON OFF ON ON 5EA 6 ON OFF OFF ON ON 6EA 7 OFF OFF OFF ON ON 7EA 8 ON ON ON OFF ON 8EA 9 OFF ON ON OFF ON 9EA 10 ON OFF ON OFF ON 10EA 11 OFF OFF ON OFF ON 11EA 12 ON ON OFF OFF ON 12EA 13 OFF ON OFF OFF ON 13EA 14 ON OFF OFF OFF ON 14EA 15 OFF OFF OFF OFF ON 15EA 16 ON ON ON ON OFF 16EA

If the first and second poles are turned off and the remaining three poles are turned on, use the first, second, and third distribution panels to use up to three distribution panels as shown in Table 2. This is the case to set.

On the other hand, if the fifth Pole is turned off and the remaining four Poles are turned on, this means that up to 16 distribution panels are used, which means that the first distribution panel is set to be used from the first distribution panel to the 16th distribution panel.

By setting the maximum number of distribution panels that can be used in this way, even if the user inputs a power supply command without knowing the situation for the distribution panels that should not be supplied with power, the microcomputer presets the distribution panel selection control switch unit. The value is read so that the power is not supplied to any other distribution board other than the distribution board set to be used.

4 shows a remote monitoring control flowchart of the distribution panel central monitoring control panel according to the present invention. As shown, when the user operates the central monitoring control panel to supply power to the distribution panel, the microcomputer 150 of the central monitoring control panel 100 operates the distribution panel remote control program, and each distribution panel from the distribution panel selection control switch unit 140. The key switch that can be used to read the setting of the local monitoring control panel or the magnetic switch of the display is used in the active mode on the touch screen 120 and performs the initialization process for remote control of the distribution panel waiting for the user's control command ( S1).

When a midnight power supply mode execution command is input to supply midnight power to each distribution panel from the user (S2), the microcomputer 150 recognizes this and transmits data for turning on each distribution panel to each distribution panel (S3). The distribution panel local monitoring control panel 200 receives this data and recognizes that the central control panel is in preparation for supplying power to each distribution panel.

The user operates the keyswitch corresponding to the branch circuit to which he wants to supply power among the activated keyswitch. The microcomputer 150 of the central monitoring control panel checks each key switch (S4), and if there is a key switch turned on by the user, the switchboard on or off data is sent to the switchboard corresponding to the key switch, and the branch circuit of the switchboard is connected to the branch circuit of the switchboard. The power distribution command is performed by turning on corresponding distribution boards and magnetic keys (S6). If it is not in the on state by searching for each key switch, a process of analyzing the state of the distribution panel is performed from the distribution panel data received from the local monitoring and control panel 200 of each distribution panel (S7).

Thus, in the initialization step (S1), only the key switch that can read and use the setting of the local monitoring control panel or the magnetic switch of each distribution panel from the switchboard selection control switch unit 140 to the active mode on the touch screen 120. According to the display it is possible to solve the problem caused by supplying power to the branch circuit that the user should not supply power in the past. Here, the distribution board control during the late night power supply has been described, but this is described as an embodiment, and the present invention is not limited thereto.

5 is a block diagram showing the configuration of a distribution panel local monitoring and control panel provided in the distribution panel.

Referring to FIG. 5, the distribution panel local monitoring control panel 200 may include a communication unit 210 for receiving a control signal from the central monitoring control panel 100 or transmitting a state of the local monitoring control panel 200 to the central monitoring control panel 100. In addition, the magnetic switch selection control switch 220 for preset use of each magnetic switch 300 provided in the distribution panel and the magnetic switch are operated to supply power to the branch circuit corresponding to the magnetic switch 300. Power control unit 280 to operate, the zero point control switch unit 270 for operating the power control unit 280 at the moment when the change in the power supplied from the outside is zero, there is an abnormality of the power supplied by the magnetic switch is operated Power detection unit 290 for detecting a signal, an alarm display unit 240 for alarming the abnormality of the power of the distribution panel, and controls each of these units and the use of the magnetic switch selection control switch unit 220 Instantaneous power change by the zero control switch unit 270 for the magnetic switch selected by the central control panel 100 according to the control signal of the central control panel 100 received through the communication unit 210 of the magnetic switch The magnetic switch 300 is sequentially operated with a predetermined delay time through the power control unit 280 to supply power to the corresponding branch circuit, and the power detection unit 290 checks for abnormal power supply. The microcomputer 230 performs power supply and state control of the distribution panel that transmits the state to the central monitoring and control panel 100, and a reset unit 250 and a clock generator 260 for the microcomputer 230. .

The communication unit 210 receives the control signal of the central monitoring control panel 100 for each distribution panel local monitoring control panel 200 by bidirectionally communicating with the communication unit 180 of the distribution panel central monitoring control panel, or vice versa in the local monitoring control panel 200. It is responsible for transmitting the power supply state of the distribution panel to the monitoring control panel 100.

The magnetic switch selection control switch 220 serves to prevent power supply to the distribution panel or the magnetic switch due to a user's selection mistake. In other words, when a branch circuit is abnormal or checks or repairs, power should not be supplied to the branch circuit. A user who does not know this operates the magnetic switch to supply power to the branch circuit from the central control panel. If an operation command is inputted, the branch circuit may be supplied with power during operation, which may result in an electrical accident. The magnetic switch selection control switch 220 is to prevent the electrical accident in advance due to the user's selection mistake.

The magnetic switch selection control switch 220 may be implemented in various forms, but will be described an embodiment using a dip switch. That is, a plurality of dip switches corresponding to each magnetic switch are installed in order to preset use of each magnetic switch. One switchboard is usually equipped with eight magnetic switches, and twelve are installed. Therefore, in the case of 8 magnetic switches, one dip switch of 8 poles may be installed correspondingly. If 12 magnetic switches are provided, one dip switch of 8 poles and one dip switch of 4 poles may be installed.

The 8-pole dip switch sets each pole to use one magnetic switch. If a pole is set to off, the magnetic switch corresponding to that pole is not used. That is, even if the user's control signal is transmitted from the central supervisory control panel to supply power to the whole branch circuit of this distribution board, if the magnetic pole corresponding to the magnetic switch 1 and the magnetic switch 2 is set to unused, the other magnetic switch is used. Power is supplied to the corresponding branch circuit by the control signal, but the unused magnetic switches 1 and 2 will not operate regardless of the user's control signal.

This is distinguished from the implementation of the magnetic switch selection control switch provided in the distribution panel selection control switch unit of the central monitoring control panel as a dip switch. That is, in the switchboard selection control switch unit, a dip switch having n poles is required as one pole does not correspond to one magnetic and the number of magnetic switches is determined according to the combination (2 ⁿ ) of all poles. However, a dip switch used in the magnetic switch selection control switch portion of the local supervisory control panel requires one pole corresponding to each of the magnetic switches.

The microcomputer 230 receives and stores individual branch circuit data and outputs control and alarm signals, and serves to supply power to each branch circuit of the distribution panel and to monitor and control the branch circuit.

The zero point control switch unit 270 operates the power control unit 280 at the moment when the change of the power supplied to the distribution board in which the local monitoring control panel is installed becomes the magnetic switch 300 connected thereto to the corresponding branch circuit. By supplying power, the board can be prevented from being malfunctioned by the power line. Here, the triac element is used to implement the power control unit 280, and the photocoupler is used to operate the triac element at the moment when the power change is zero.

The power detector 290 monitors whether or not the magnetic switch 300 is properly supplied with respect to the power supplied through the magnetic switch when the magnetic switch 300 is operated to supply power. If an abnormality is detected in the power of the magnetic switch 300, the abnormal state is immediately notified to the microcomputer 230.

Looking at the operation of the distribution panel local monitoring and control panel 200 configured as described above are as follows.

First, the magnetic switch control signal transmitted from the central monitoring control panel 100 is transmitted to the microcomputer 230 for monitoring and controlling the distribution panel through the communication unit 210 of the RS 422 communication method. At this time, the microcomputer 230 interprets the control signal of the central monitoring control panel 200 by reflecting the setting value of the magnetic switch selection control switch 220. The power line selection signal for the branch circuit selected under the control of the microcomputer 230 passes through the photo coupler 270, which is a zero point control switch, to the gate of the triac 280, which is a power control unit, to shield the influence of the external power of the board. Delivered.

Accordingly, the triac 280 is driven to operate the magnetic switch to supply power according to the power line selection of the user. The supplied power flows to the power detection unit 290 of the reed switch operation detection method, and at this time, the power detection unit 290 transmits an abnormal status signal of power to the microcomputer 230 of the local monitoring control panel. If a power supply abnormality such as a power failure occurs, the microcomputer 230 of the distribution board transmits an alarm signal to the microcomputer 150 of the central monitoring control panel, and simultaneously displays it externally through an LED (alarm display) 240 attached to the distribution board. give.

Even if a power line abnormality occurs by such an operation, the central monitoring control panel 100 can be confirmed by the liquid crystal display in the magnetic unit of the distribution panel 200, and the electric power is displayed by the alarm display unit 240 of the distribution panel when repairing the identified power line. By checking the abnormal condition again, it is possible to secure the reliability of maintenance and repair.

According to the present invention, the power control of small buildings and major equipments can be carried out at a low construction cost, and there is a power saving effect by the user monitoring and controlling the power status conveniently, and quickly and safely maintenance and repair and electrical accidents Not only can it cope with the problem, it also provides the effect of eliminating the risk of electric accidents due to the sequential power supply.
