Description

Access security automation unmanned substation system, unmanned substation access security automation device and unmanned substation automated access security method

The present invention relates to an unmanned substation access security automation device and an automated access security method for performing an access security procedure for vehicles entering/exiting an unmanned substation based on IoT.

Most of the recently constructed unmanned substations are remotely monitored and controlled at the dispatch branch, and a management system is operated to monitor and control the site at the unmanned substation.

A conventional unmanned substation management system includes an alarm receiving interface unit (AIU) into which data signals transmitted from crime prevention and fire detectors are input, an image transmission system that controls image monitoring by being connected to a communication module of the alarm receiving interface unit, and the above An alarm receiving panel into which monitoring information output from the alarm receiving linkage panel is input, a remote control system (SCADA) that remotely monitors through data transmitted from the alarm receiving panel, and security devices installed in a company in charge of guarding an unmanned substation A guard system that outputs an armament signal for switching to a guard system, an access management system that receives the armament signal of the guard system and controls entry and exit of the front door and the front door, and an arming port for transmitting the control signal of the alarm receiving panel to each facility. Each expander is provided and operated.

In this management system, the structures of the alarm receiving linkage unit, the warning receiving unit, and the armed port expander are installed in a complex manner, and similar functions are operated in conjunction with each other.

In addition, management of access control is difficult because production of the alarm receiver is stopped and management such as maintenance is difficult, and it is inevitable to release the security boundary state when the access control system is broken or the crime prevention and fire detectors malfunction.

1 is a procedure diagram showing a process for permitting advance access to an unmanned substation in Korea.

Currently, company employees who manage unmanned substations connect to the in-house (KEPCO) integrated access management system, and outsiders connect to the external e-access management system and apply for access to the unmanned substation, which is automatically distributed to the supervisory department, and the final review by the security department after the first review. and access is approved, the pre-approval process for the unmanned substation is completed, and it is operated in such a way that internal employees use an employee ID card and outsiders can access the unmanned substation with the pass issued, which takes considerable time.

In particular, while access to unmanned substations is infrequent, it is difficult to implement drive-through access control because a very high level of security is required for access security of unmanned substations, which are national security self-protection facilities.

In addition, the fact that access is not frequent and there are no resident personnel is often abused by vehicles illegally parked at the vehicle entrance of an unmanned substation, which further becomes an obstacle to personnel entering and exiting for maintenance.

We will take a closer look at the problems, such as inconvenience, high cost, and low efficiency, when entering and exiting an unmanned substation, briefly discussed above.

2 is a flowchart illustrating processes from entering an unmanned substation using a vehicle according to a current business procedure to leaving the station.

As shown in the figure, a total of 14 steps are performed, from the arrival of the vehicle for maintenance to the entry and exit of the substation, which can increase the inconvenience of visitors especially in rainy weather, snow, and winter. Numerically, an average of 20 minutes of vehicle entry/exit delay (entry 10 minutes, exit 10 minutes) always causes dissatisfaction with visitors, and there is a high possibility that facility restoration will be delayed due to entry/exit problems in case of facility failure or power outage. : 14 steps, discharge: 24 steps)

3A and 4B are reference diagrams and related case photos showing an entry inappropriate state due to a temporary parking situation in front of the gate of an unmanned substation.

Areas where these cases occur include traffic congestion in the city, dense shopping malls, knowledge industry centers, and substations adjacent to construction sites, which are unsuitable for temporary parking environments. That is, due to the narrow parking space, the vehicle occupies the sidewalk and obstructs the passage of the public, and the risk of traffic accidents caused by drivers temporarily parked and stopping and the threat of injury such as momentary collisions with vehicles traveling along the roadside increases. In addition, the risk of traffic accidents increases when the general public walks around the sidewalk blocked by the road.

Regarding maintenance, the possibility of civil complaints increases due to delays in power outages/failure recovery due to delays in entry and exit by unauthorized parked vehicles.

Looking at specific examples, it takes an average of 10 minutes to leave an unmanned substation using a vehicle, and it may be delayed by more than 20 minutes if there is an unauthorized parking vehicle in front of the main gate. The delay in facility restoration due to such facility failures and entry/exit problems during power outages was the biggest concern of civil complaints in power grid maintenance.

The vehicle entry/exit detection coil 1 and the vehicle entry/exit detection coil 2 shown in FIG. 11 detect and transmit two vehicle entry/exit signals to the vehicle entry/exit detection coil unit 5. Meanwhile, in FIG. 11, the vehicle entry/exit/unauthorized parking detection coil 3 and the vehicle entry/exit/unauthorized parking detection coil 4 detect three signals of vehicle entry/exit/unauthorized parking with the vehicle entry/exit detection coil part 6, can transmit

In order to detect habitual unauthorized parking and induce mobile parking, in FIG. By comparison, the existing access control alarm ACU interface device (100) detects habitual unauthorized parking and simultaneously transmits a signal to the warning light (11), LED signboard text part (12), and audio part (Speaker) (13) side, so that the warning light (11) This flashes in red, and the “unauthorized parking guide text” is displayed on the LED signboard text part 12 and at the same time broadcast within 15 seconds through the speaker of the audio part 13, so that the illegal parking driver recognizes these three pieces of information at the same time It can play a role of inducing the vehicle to move to another place.

The illustrated warning light 11 flashes red light for each situation when entering/exiting a vehicle and detecting unauthorized parking, and plays a role in alerting the person entering and exiting, and the LED signboard text part 12 and audio part (Speaker, 13) is normal mode, vehicle entry mode. It operates simultaneously in four modes, vehicle exit mode and unauthorized parking detection mode, and can be expressed in text and voice at the same time.

12 shows a total of four mode text and voice expression field implementation devices for unauthorized parking.

12 is a device implemented in the field for a total of four modes of text and voice expression, and the content of the expression is as follows.

- Unauthorized parking detection mode: This is a vehicle entrance for emergency recovery of electrical failure, and unauthorized parking is reported to the public service, so please move and park elsewhere.

- Vehicle entry mode: The electric gate opens. Please enter safely by paying attention to traffic collisions

-Vehicle exit mode: The electric gate is closed. Be careful of vehicle collisions and leave safely

- Normal mode: This is a vehicle entrance for emergency recovery of electrical failures, and unauthorized parking is reported to the public service, so please move and park elsewhere.

Depending on the implementation, if unauthorized parking continues to be maintained despite the above-described announcement about unauthorized parking, a report may be actively performed to an external enforcement agency such as a government office or a police station.

To this end, the ACU interface device recognizes that an unauthorized parking vehicle exists in front of the gate for entering and exiting the unmanned substation from the result of detecting the loop coil or analyzing the CCTV screen for the unmanned substation. A warning about unauthorized parking is broadcasted through an output device, and if the vehicle does not move even after the standard waiting time elapses after the warning broadcast, an external agency such as a police station may be notified.

In addition, as a result of checking from the access management server at the time of notification, if there is an application for access to the unmanned substation within the standard scheduled time, it may be notified as an emergency action request.

On the other hand, the unmanned substation access security automation device of the present invention can support the simultaneous entry and exit of a visitor + vehicle.

In the past, it was impossible to distinguish the situation in which a person entered or a vehicle entered because only an employee ID or pass was used to touch the card reader at the front door to disarm and operate the E/M Locking of the main door.

14, the employee ID tag signal is first transmitted from the IoT vehicle access security WRC terminal inside the vehicle, and then the signals from the entry/exit/unauthorized parking detection coils 3 and 4 are transmitted to the existing access management alarm ACU When transmitted to the interface device device 10), it can be compared and regarded as a simultaneous entry/exit signal of a human + vehicle. among these Employee ID tagging signal takes precedence, When there is no employee card tagging signal, no operation can be controlled.

Those skilled in the art to which the present invention pertains should understand that the embodiments described above are illustrative in all respects and not limiting, since the present invention can be embodied in other specific forms without changing the technical spirit or essential characteristics thereof. only do The scope of the present invention is indicated by the claims to be described later rather than the detailed description, and all changes or modifications derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention. .
