Description

DETAILED DESCRIPTION OF THE INVENTION [Technology of the Invention] The present invention relates to a traffic control device that monitors unauthorized entrances and exits to a specific area, and in particular detects unauthorized entrances and exits to a specific area according to the situation at the entrance and exit. The present invention relates to a traffic control device that can detect quickly and reliably by changing conditions.

[Prior Art] Conventionally, this type of device has been used in specific areas that require special monitoring, such as computer centers, financial institutions, and nuclear power plants, and intrusion detectors that monitor the surroundings of the areas. It was also constructed with a traffic control door that controls the passage of passersby by determining whether or not passersby are allowed to pass by using a plurality of determination means. However, the above-mentioned intrusion detector independently monitors the traffic control door provided at the entrance/exit, regardless of whether it is in normal or emergency conditions. In particular, intrusion detectors are installed outdoors, so multiple types of intrusion sensors are installed in parallel to prevent malfunctions due to weather or the influence of birds and animals, and all of these multiple types of intrusion sensors are operating normally. It was assumed that unauthorized entry and exit had been made in the case.

However, the intrusion detector of the conventional device described above always judges unauthorized entrances and exits based on regular conditions, so even if an emergency situation occurs at the traffic control door, the detection sensitivity is low. Since intrusion detection is performed, there is a possibility that prompt and reliable detection may not be possible.

[Summary of the Invention] The present invention has been made in view of the above points, and the detection conditions of an intrusion detector that monitors unauthorized entrances and exits in the outer periphery of a specific area are determined based on the condition of the traffic control door installed at the entrance and exit of the specific area. The purpose of the present invention is to propose a traffic control device that can quickly and reliably detect intrusion, etc. by changing it accordingly.

It consists of

Next, the operation of this embodiment will be explained. First, the illegal traffic detector (
5) does not send out the illegal traffic signal S3 (that is, when the illegal traffic is not detected at the entrance/exit (2)), the passerby inserts the card into the outer card reader (42) and reads the card memory (43). When the card data matches the card data, the door unlock signal S1 is activated by the locking mechanism (
(not shown), and by the unlocking operation of the locking mechanism, the door body (21) is unlocked, allowing the passerby to pass through.

In addition, in the case where the illegal traffic signal S:I is not sent from the illegal traffic detector (5) as in the above case,
When an intrusion state of an outsider occurs in the area (a), both the vibration sensor (32a) and the optical sensor (31a) output detection signals, and the AND circuit (33a) and the OR circuit (
A set signal is sent to the RS flip-flop (38a) via 34a). The RS flip-flop (38a), which has been set to the set state by inputting the cell/) signal, lights up the lamp (37a) and causes the bell (38) to sound an alarm, thereby indicating that there is an intrusion in the area ('a). Notify the administrator of the occurrence. Furthermore, the above administrator shall be responsible for the area (a)
) By displaying the image signal sent out by the ITV (71a) that monitors the intrusion site on the monitor TV (74), the intrusion site can be visually confirmed and predetermined measures can be taken. Note that after the predetermined measures are taken against the intrusion, the manager presses the reset button (35) to reset the RS flip-flop (3fla) and return it to its initial state.

Next, if the illegal passage signal S3 is being sent from the illegal passage detector (5), for example, a passerby who is going to go outside from the building (1) does not insert the card into the card reader (41), Or even if the card is inserted, the match detection circuit (44
), the door unlock signal S1 was not sent out because no match was detected, and furthermore, the passerby forced the door (21) open or destroyed it to pass through the door illegally, so the door state was not detected. The circuit (51) will send out the door open signal S2, and the illegal traffic detector (5) will send the illegal traffic signal S3.
is being sent. In this case, the illegal traffic detector (5) causes the bell (55) to sound an alarm, displays on the display (51) that there has been illegal traffic, and notifies the manager. Furthermore, the passerby who was illegally passing through the vehicle was detected by the optical sensor (31a) ~(
31d) or the vibration sensor (32a) to (32d) and is detected by any of the above sensors, the intrusion detector (3) is set by the condition change setting device (6).
Either of the detection signals S4a"S4d will be sent out, and it can be determined whether the illegal passerby is in any of the areas. Moreover, the presence of the illegal passerby can be visually confirmed by the ITV confirmation device (7). Regarding the subsequent procedures, the same measures as in the case where the illegal traffic signal S3 is not sent are taken.

In addition to the above embodiments, the present invention can be carried out in the following manner.

[1] The intrusion sensor may also be configured with an electric field type sensor, a microwave type sensor, a sensor using pattern recognition, or the like.

[21 The traffic control door can also be configured with a swing type, a rotating type, a vertically moving type, or a type of control door that performs 10 determinations between two doors. Furthermore, an automatic door can be used instead of a manual door.

[31 A traffic control door can also be constructed using a normally closed door that is not subject to traffic control (for example, a door that can be opened with a key only in an emergency, a shutter, or a door that a manager manually controls to open and close with an electric lock from a remote location). In this case, it is not necessary to install an ID discriminator.

[4] Another set of fences may be installed in a wider peripheral area, and a dual intrusion sensor may also be installed on this installed fence.

[5] When there are many doors, the configuration may be such that only intrusion sensors near the illegally opened door are used as the OR condition.

[61] An intrusion detector formed by providing three or more intrusion sensors may also be used.

[Effects of the Invention] As explained above, the present invention sets the detection conditions of an intrusion detector that monitors unauthorized entrances and exits on the outer periphery of a specific area based on the control results of the traffic control door provided at the entrance and exit of the specific area. Since the structure is configured to change the temperature, it is possible to eliminate the influence of weather and the like even outdoors, and to prevent malfunctions as much as possible, and it is possible to quickly and reliably detect an intrusion by an intrusion detector.
