Description

Detailed Description of the Invention

  The present invention uses an electromagnetic lock device that locks an automatic door with an electromagnet and an adsorption plate. The electromagnetic lock device is provided with a limit switch that is turned on when the door is moved in the release direction. The present invention relates to a security device for an automatic door in which an alarm / intimidation device is activated by a signal from the limit switch to prevent the automatic door from being damaged by a criminal in advance.

  For example, Patent Document 1 states that “a pulse signal output for detecting a position at the time of opening / closing a door is used and an alarm signal necessary for crime prevention measures is used depending on a control state of an electric lock controlled by a door controller. The door controller determines whether or not the generation is necessary, and the door controller generates and transmits an alarm signal when it is determined that the alarm signal needs to be generated, specifically, the electric lock is in the locked state. Despite the fact that the door controller recognizes that, the suspicious person is forcibly unlocking or damaging the electric lock, for example, and opening the door by counting the number of pulse signals. A warning signal is generated, and it is possible to reduce the number of parts, reduce costs, improve work efficiency, and expand the scope of security measures. Alarm signal generation output method in the door controller of the door device and an automatic door system "is described.

  And, "a pulse signal proportional to the amount of movement of the door from a sensor attached to the motor of the drive mechanism that opens and closes the door for detecting the brake position, fully open position, and fully closed position at the time of opening and closing the door; Determining whether the alarm signal needs to be generated based on the control state of the electric lock provided for locking the door, and if the generation of the alarm signal is determined, Is provided "(paragraph 0006).

  “When using the pulse signal output for position detection at the time of opening and closing the door, the door controller determines that the alarm signal needs to be generated according to the control state of the electric lock controlled by the door controller. It is described that "the alarm signal is generated and transmitted" (paragraph 0007).

  Furthermore, “Since the door controller recognizes that the electric lock is in the locked state, the suspicious person forcibly unlocks or breaks the electric lock, for example, by measuring a predetermined number of pulse signals. It is considered that the door is open, and in this case, the door controller determines that the intrusion has occurred and generates an alarm "(paragraph 0011).

  However, in the invention described in Patent Document 1, a door controller that determines whether or not an alarm needs to be generated is determined by a predetermined number of pulse signals proportional to the amount of movement of the door from a sensor attached to a motor of a drive mechanism that opens and closes the door. It is necessary and does not directly detect the movement of the door in the opening direction, but immediately detects a slight movement of the door with a reed switch and instantly determines the automatic door breakage by the criminal and alerts・ The threatening device cannot be activated. Further, the configuration is extremely complicated and cannot be provided at a low cost.

  Patent Document 2 states that “a security sensor system for window glass is installed in the vicinity of a window glass that partitions the room from the outside, and has a first human body detectable area outside the window glass. A security sensor system for glass that is advantageous for detecting a suspicious person who breaks the window glass and enters the room by including a sensor and a second sensor in the second human body detectable area on the indoor side of the window glass Is provided ".

  "The second human body detectable area of the second sensor is expanded to the first space through the broken space portion of the window glass when the window glass is broken", and "the first sensor is Based on the electromagnetic waves that are installed in the second space and pass through the window glass, the human body existing in the first human body detectable area on the first space side partitioned by the window glass is detected. " . (Claims 2 and 3)

  However, the invention described in Patent Document 2 does not threaten the criminals in advance of the automatic door opening breakage at the time of illegal intrusion, and does not directly detect the movement of the door in the opening direction. Therefore, it is impossible to immediately detect a slight movement of the door and to judge the damage of the automatic door by the criminal and to activate the alarm / intimidation device. Furthermore, it does not use an electromagnetic lock device that locks the automatic door, and the configuration becomes extremely complicated and cannot be provided at low cost.

  Patent Document 3 states that “an imaging unit that is a CCD camera having an internal unit provided inside a door and an external unit installed outside the door and provided through the internal and external units; The image pickup means arranged at a position different from these units picks up a visitor, and the internal unit monitors image information from these three image pickup means that have started image pickup by the ON operation of the person detection sensor, and Among them, when it is no longer possible to receive image information from scratch, it is judged that there was malicious intent such as destruction of the imaging means, an alarm sound is generated, a strobe light is turned on, etc., and further mischief or crime is performed By providing abandonment, an external visual recognition system configured to determine the good intentions and bad intentions of visitors and take appropriate measures is provided. "

  Then, “... the device set in the absence mode starts recording together with imaging. In this case, the central processing unit of the internal system monitors whether all of the plurality of imaging means are imaging, If image information is no longer input from some of the imaging means, an alarm is issued as if there is a change .... The person detected by the sensor is a person who came home with criminal or malicious intentions such as the picking crime, mischief, etc. In some cases, if you are the person, you will be perceived by the fact that you are being imaged and recorded, and you will immediately run away without committing a crime or mischief, and the crime or mischief will be unsuccessful. Because it is practically impossible to break down the imaging means or to make it non-functional by covering the lens, etc., it is also possible to destroy or de-function multiple imaging devices at the same time. Since it is practically impossible, at the time when the image information is interrupted by a plurality of image pickup means, are ... "effect described issuing an alarm as there accident. (Paragraphs 0009-0011)

  However, in the invention described in Patent Document 3, as many as four image pickup means (1, 2, 7, 8) are required, and not only an accurate position setting of a camera as an image pickup means is required, but also a security device. The whole becomes complicated and expensive. In addition, it does not directly detect the movement of the door in the opening direction, but immediately detects a slight movement of the door with a reed switch and instantly determines whether the criminal breaks the automatic door and activates an alarm / intimidation device. I can't. Furthermore, it does not use an electromagnetic lock device that locks the automatic door, and the configuration becomes extremely complicated and cannot be provided at low cost.

Patent Document 4 states that “a crime prevention system that detects that a criminal has entered the crime scene and abandons this crime, and a detection signal is sent when a criminal enters the detection area where the criminal is estimated to be committed. For example, a far-infrared gland sensor which is an output security sensor and a pulse signal E ₁ having a detection unit time of a repetition period T ₀ , and as a result of comparison operation with respect to the input of the detection signal, are regarded as suspicious behavior. In such a case, an anti-crime control device A ₁ that performs a threatening process P ₂ that outputs a threatening signal, and a threatening device C that threatens the criminal in response to the input of the threatening signal, and an action that is predicted to be a criminal. Only the suspicious person is prevented from incurring these crimes by minimizing the damage by intimidating menace and applying psychological pressure before the key is destroyed or the door is opened. Keep to the limit "Security system" is described.

  And, “in the security control device in the standby state, the first detection signal of the security sensor is input and the count process for counting the detection unit signal is started by shifting to the warning state, and the predetermined end condition is not reached. As long as in the threatening process, it is determined whether a detection unit signal of a specific detection count number is transmitted according to the characteristics of various crimes, and when a detection unit signal of the detection count number is transmitted, Detects the detection signal of the security sensor every time, and when the detection signal input is detected, outputs a threat signal each time, threatens the criminal intermittently by the threat device, and thereby the crime I will give up and prevent it in advance. " (Claim 1)

  In addition, "To prevent crimes by criminals who remain in the detection area even after intermittent threatening, determine whether a detection unit signal of a specific migration count number is transmitted according to the characteristics of various crimes, When the detection unit signal of the count number is transmitted, the threat process is terminated and the process proceeds to the alarm process. If the predetermined termination condition is not reached, whether the detection signal of the security sensor is input in the alarm process When a detection signal is detected and an input of a detection signal is detected, an alarm signal is output and an alarm device issues an alarm to a criminal. (Claim 2)

  However, in the invention described in Patent Document 4, it is necessary to determine whether a detection unit signal having a specific number of transition counts according to the characteristics of various crimes has been transmitted. A discrimination circuit is required, and the entire apparatus becomes complicated and expensive. In addition, it does not directly detect the movement of the door in the opening direction, but immediately detects a slight movement of the door with a reed switch and instantly determines whether the criminal breaks the automatic door and activates an alarm / intimidation device. I can't. Furthermore, it does not use an electromagnetic lock device that locks the automatic door, and the configuration becomes extremely complicated and cannot be provided at low cost.
