As shown in Figure 1, the outlet load control system of the office building of the present invention is the entrance detection system 10 installed in the building entrance and exit, the server 20 and the input / output unit 21 of the disaster prevention room, the communication unit of the power control panel 30, a relay 40, a local switch 60, a power supply 80, and an office outlet 50 of the office.

The entrance detection system 10 detects a worker's entrance and exit, and sends a detection signal, and an entrance control system 11 or an unmanned security system 12 that detects and controls a worker's entrance may be used. have.

The access control system 11 is installed at an entrance in most large office buildings recently to detect an access state and control access by using a means having unique identification information of a worker or an outsider. The entrance detection system 10 already installed in a building can also be used as it is.

The means having the unique identification information, for example, RFID card recognition means using the user's name, employee number and card number information, fingerprint recognition means using the user's fingerprint information, iris recognition means using the user's iris information, Face recognition means for recognizing the user's face, voice recognition means using the user's voice, etc. may be used.

The dispatch security system 12 is a system that detects that all workers have left the office and monitors external invaders, and sends an intrusion signal to an external security company when there is an external invader. It is available.

As the server 20 of the disaster prevention room controls the entire system, the entrance and exit of the worker is determined by the signal from the entrance detection system 10 described above, and an on or off signal is sent. It may also send on / off signals according to a predetermined time schedule. The input / output unit 21 generally means a keyboard for inputting an operation signal and a monitor on which a control state is displayed.

The telecommunication unit 30 transmits a control signal to the relay 40 according to the signal transmitted from the server 20 to turn on / off the relay 40. The communication unit 30 may use PLC communication, RS-485 communication, and the like that transmit and receive digital signals using a power line.

The relay 40 is provided in large numbers by being turned on or off in accordance with the presence or absence of a control signal from the communication unit 30 to supply or cut off power.

The outlet 50 is connected to the relay 40 and is capable of plugging in a plurality of electric appliances such as a personal computer. Here, the outlet 50 is used to include a general outlet and a system box. Common outlets include a built-in wall outlet and an exposed wall outlet. The system box is composed of several outlets and is a kind of outlet.

As shown in FIG. 1, a plurality of outlets 50 may be controlled by one relay 40, and the outlets of related workers in the office may be bundled into one zone to be turned on / off together. It can also be configured to be turned on and off at the same time for each floor. It is also possible to selectively control only one outlet with one relay.

The local switch 60 transmits an operation signal to the communication unit 30 so that the relay 40 connected to the outlet 50 of the worker keeps the on state if necessary, regardless of whether the worker leaves the room. . For example, when a co-worker next to work leaves the office but needs to use a co-worker computer to work, if the local switch 60 is activated, the communication unit 30 sends a control signal of ON to relay. 40 can be turned on continuously to allow the computer to operate.

If necessary, the local switch 60 is manually turned on by the worker, and the local switch 60 may not be manually operated. The reason is that it can be turned off by the operator unintentionally.

In addition, the local switch 60 may be configured to collectively control the relays 40 to turn on / off the corresponding outlets 50 of the workers working in the zoned zone in the building, It may be configured to individually control the relay 40 to turn on / off of the 50).

The outlet load is controlled through the step of determining whether to leave (S4), determining whether to switch on locally (S5), continuing to supply current (S6), and shutting off current (S7).

First, the entrance detection step S1 is a step in which the entrance detection system 10 detects a worker's entrance and transmits an entrance signal to the server 20 in the case of entrance. When the entrance detection system 10 is the access control system 11, the worker detects an entrance state by checking a means having unique identification information when the building enters and exits, and the entrance detection system 10 sends the dispatch guard system 12. In the case of the user, the access state is detected by information input at the time of commute and leave of the user. The access control system 11 is suitable for a large building and the dispatch security system 12 is suitable for a small building.

The current supply step (S2) is a server in the entrance detection step (S1) in the state of entering the signal sent to the communication unit 30, the communication unit 30 is connected to the outlet 50 of the worker The control signal is sent to the relay 40 to turn on the relay 40 and supply electric current to the electric appliance.

In the exit detection step S3, the entrance detection system 10 detects a worker's departure and sends a departure signal to the server 20 in the case of leaving. In the case of the departure detection step (S3), if the corresponding worker is leaving the office, all the workers in the zone are again determined whether or not to perform the departure (S4) for all employees in the zone.

In the case where all workers in the zone are not released, the local switch 60 determines whether the local switch 60 is on (S5). do.

When the local switch 60 is turned on in the step of determining whether to switch on the local switch (S5), the relay 40 is continuously turned on to perform the current continuous supply step (S6) of supplying current to the electric appliance. This is useful when a non-working worker wants to use the computer of a colleague who has left work.

When the local switch 60 is not on in the local switch on determination step (S5), the server 20 sends an off signal to the communication unit 30, and the communication unit 30 is the outlet 50 of the worker. Blocking the control signal to the relay 40 connected to the off to perform a current blocking step (S7) to cut off the current to the electrical appliance to turn off the relay (40).

In the step (S4) of all workers in the zone, the current blocking step (S7) is performed even when all workers are leaving, and this step is performed when all the workers in the zone have left. This is because the power must be cut off at (50).

If a worker needs to go down the office and check for data down, virus check, program operation, etc., ask the staff of the disaster prevention room to operate the input / output unit 21 to allow the server 20 to come to the relay 40 for a predetermined time. You can make your computer run by sending an (on) signal.

The outlet load control system of the office building of the present invention can be controlled as follows. That is, as shown in FIG. 3, for example, the server 20 regardless of the detection signal from the entrance / exit detection system 10 in order to supply electricity to all the outlets at all times regardless of the worker's entrance and departure during the working hours. A schedule for sending an ON signal to the communication unit 30 and the communication unit 30 sends a control signal to the relay 40 connected to all the outlets 50 to turn on the relay 40 and supply current to the outlet and the electric appliance. Control is performed.

In addition, it is possible to perform access interlocking control to turn on or off the relay 40 according to the detection signal from the access detection system 10 until the next day after the leaving time.

In addition, in the case where the local switch 60 is turned on together with the access interlocking control until the next day after the leaving time, it is related to the detection signal of the entrance detecting system 10 until all the workers in the zone leave. The relay 40 may be continuously turned on without causing local control of supplying electric current to the electric appliance.

For example, referring to the time chart of FIG. 4, a schedule control is performed during work hours from 08:30 am to 18:00 pm to turn on the relay 40 regardless of the employee's departure and to turn off all the outlets 50 and Supply current to the connected electric equipment, and if not working hours from 18:00 PM to 08:30 the next day, the access interlocking control in conjunction with the worker's entrance and exit. In addition, manual control can be performed in parallel with local control.

On the other hand, electrical appliances and facilities that must always be supplied with electricity, such as a fax machine, a refrigerator, a bending machine, a fire-fighting facility, and always supply electricity regardless of the outlet load control method described above.
