[Prior art]

Conventionally, this type of equipment includes intrusion monitoring equipment that monitors the surroundings of specific areas such as computing centers, financial institutions, and other important facilities that require special monitoring, and intrusion monitoring equipment that monitors the suitability of passersby at the entrances and exits of the areas. It is often constructed in conjunction with an entrance/exit control device that uses a plurality of discriminating means to discriminate and control traffic. However, in the conventional device described above, the entrance/exit control device operates all the discriminators (e.g., card reader, numeric keypad, handprint discriminator, etc.) that are multiple discriminating means independently of the monitoring results of the intrusion monitoring device. Since the condition for passing was that all the determination results of the levers were satisfied, if the intrusion monitoring device did not detect an abnormality or intrusion of a person, in other words, an outsider entered the area monitored by the intrusion monitoring device. Even in a state in which a passerby who is an insider and is entering a specific area cannot pass through without being judged by all the discriminators in the entrance/exit control device, excessive judgment operations and judgment time are required to pass. It required

Further, a command indicator light 62 is provided in the entrance/exit 2 to instruct the operation of the handprint discriminator 44 when the inner circumference intrusion sensor 32 outputs an output.

Next, the operation of this embodiment will be explained. First, in a normal state where both the outer and inner sensors 31 and 32 do not detect an intrusion, the most important area a
Traffic control to building 1 within the building is such that passers-by can
Open 1 and enter entrance 2, card discriminator 41
When the weight discriminator 42 determines that the body weight matches the allowable weight value, an unlock signal is sent and the door 72 is unlocked for 5 seconds. During this time, a passerby can push open the door 72 and enter the building 1.

In addition, the card discriminator 41 and the weight discriminator 42
If either or both of them do not detect a match, the passerby will not be able to enter the building 1.

Next, if the outer peripheral intrusion sensor 31 detects an intrusion, the RS flip-flop 312 is set, the lamp 314 indicating intrusion lights up, and the bell 315 sounds an alarm, and the OR circuit 3
An output signal is sent from 17, and the command indicator light 61 provided in the entrance/exit 2 lights up in response to the output signal, instructing the numeric keypad discriminator 43 to be operated. A passerby operates the numeric keypad discriminator 43 in accordance with the instruction, and if a match is detected, the logical product condition of the AND circuit 53 of the traffic regulator 5 is satisfied, and an unlock signal is sent to the door 72. is unlocked for 5 seconds. Meanwhile, passersby pushed open door 72 and opened building 1.
You can go inside.

The manager who learns of the intrusion into the important area b from the lamp 314 and bell 315 of the outer intrusion sensor 31 confirms whether or not there is an intrusion using a confirmation means such as an ITV (not shown). After it is confirmed that there is no intrusion, or after the predetermined measures have been taken against the intrusion, the manager presses the reset button 313 to reset the RS flip-flop 312 and turn off the lamp 314.
By stopping the alarm bell 315 and turning off the command indicator light 61, the traffic control returns to the normal state.

Further, if the inner circumference intrusion sensor 32 detects an intrusion, the RS flip-flop 322 becomes set, the lamp 324 indicating intrusion lights up, the bell 325 sounds an alarm, and the OR circuit 327 outputs a signal. The command indicator lights 61 and 62 provided in the entrance/exit 2 are both turned on by the signal, and the numeric keypad discriminator 43 and the handprint discriminator 4
Instruct the user to perform step 4. If the passerby operates the numeric keypad discriminator 43 and the handprint discriminator 44 in accordance with the instructions, and a match is determined, the logical product condition of the AND circuit 53 is satisfied, and an unlock signal is sent. The door 72 remains unlocked for 5 seconds, allowing passersby to enter the building 1.

When the manager learns that the most important area a is intruded from the lamp 324 and bell 325 of the inner intrusion sensor 32, he confirms whether or not there is an intrusion using a confirmation means such as an ITV (not shown). After it is confirmed that there is no intrusion, or after the predetermined measures are taken against the intrusion, the manager presses the reset button 323 to reset the RS flip-flop 312 and return to normal traffic control. That will happen.

Furthermore, even if the outer or inner intrusion sensors 31 and 32 do not operate, the manager can press the manual selection switches 316 and 326 when he or she determines that the traffic conditions should be made stricter than normal. Therefore, the same traffic control as when the intrusion sensors 31 and 32 detect an intrusion is possible.

In addition to the above embodiments, the present invention can be carried out as follows.

The contents of the discriminator that is activated when an intrusion occurs may be changed. For example, the order of the handprint discriminator and the numeric keypad discriminator may be changed.

Although four types of discriminators are illustrated, other types of discriminators (voice print, fingerprint, etc.) may be added, or the use of four discriminators may be limited to three (for example, handprints should be stopped, and intrusions on the outer periphery should be stopped). You can make use of your body weight by using the keypad, and make use of the numeric keypad by invading the inner periphery), or you can change the order in which you make use of them.

The determination may not be performed simultaneously, but may be configured such that the next determination is performed one after another after each vehicle has been granted permission to pass.

When many traffic control doors are arranged, the doors may be opened in stages by making the positions of the doors or the importance of their contents correspond to the detection state of the intrusion detector.

The intrusion detector is constructed so that one more intrusion detector is added to the outer periphery, and the traffic conditions are weighted for the outermost and middle outer peripheries, and for the middle and inner outer peripheries, respectively. It's also good.

〔Effect of the invention〕

As described above, the present invention provides a first intrusion detector on the outer periphery of a specific area and a second intrusion detector on the inner periphery of the first intrusion detector, and detects these intruders. In so-called normal times when none of the detectors are in the detection state, passage to the specific area is permitted based on the determination result of the first intrusion detector, and in so-called emergency times when the first intrusion detector is in the detection state, the first intrusion detector is in the detection state. Passage to the specific area is permitted by weighting the discrimination result of the second discrimination means with the discrimination result of the second discrimination means, and furthermore, when the second intrusion detector near the specific area is in the detection state, the first intrusion detector The determination result of the third determination means is added to the determination results of the determination means and the second determination means to permit passage to a specific area.

Therefore, during normal times when there are no outside intruders in the specific area, it is easy to input signals at the entrance and exit, allowing smooth passage. Furthermore, in the event of an emergency using the first intrusion detector, the second discrimination means is added to the first discrimination means to make the discrimination more severe, so that it is possible to prevent an intruder from entering a specific area. Furthermore, when an intruder approaches a specific area and the second intrusion detector becomes an emergency, the third discrimination means is added to the first and second discrimination means to make it more strict. Therefore, there is an effect that intrusion by intruders can be more strictly prevented.
