The present invention relates to the field of security technology, and more particularly to an intrusion alarm device, method, security system, and opening and closing system.

The security alarm system is mainly composed of the front-end equipment/unit and the alarm processing equipment/unit. The large-scale wireless security alarm system is mainly composed of the front-end transmitting equipment/unit alarm processing equipment/unit and the alarm monitoring center. In the event of an alarm, the front-end device/unit performs an alarm (such as sending an alarm signal to the alarm processing device/unit), and the alarm processing device/unit performs alarm processing on the alarm of the front-end device/unit, such as automatically dialing the preset. Number or communicate with the Alarm Monitoring Center and more.

Detectors, smoke detectors, etc. Among them, the intrusion alarm device/unit is generally composed of a magnet and a reed switch circuit, and its working principle is: when the magnet is close to the reed switch (that is, when the opening and closing mechanism is in the closed state), the two metals in the reed switch After the sheets are magnetized, they are attracted to each other and are in a state of no alarm. When the magnet is away from the reed switch (that is, when the movable portion of the opening and closing mechanism moves away from the fixed portion), the two metal pieces in the reed switch are separated from each other due to the disappearance of the magnet, and an alarm is issued. Such intrusion alarm devices/units are prone to false alarms or leakage alarms due to magnetic field interference: for example, in the event of other magnetic fields approaching (such as magnetic fields generated by magnets or high-power electrical equipment/units), intrusion The magnetism of the magnet in the alarm device/unit will temporarily increase or decrease or even be eliminated, resulting in the two metal pieces in the reed switch not being able to be separated or attracted to each other, and thus causing a leak alarm or false alarm. Summary of the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any inventive effort are within the scope of the present invention.

The existing intrusion alarm device/unit is generally composed of a magnet and a reed switch circuit, and uses whether or not the metal piece in the reed switch is magnetized to cause suction or separation to judge whether or not to alarm. When the intrusion alarm device/unit encounters another magnetic field (such as a magnetic field generated by a magnet or a high-power electric unit device/unit), the magnetic properties of the magnet temporarily increase or decrease or even eliminate, resulting in the reed switch. Metal sheets cannot be separated or attracted to each other, and it is easy to cause a leak alarm or a false alarm. In particular, when the intruder understands the implementation principle, the magnetic metal detector can first be used to determine the location of the intrusion alarm device/unit, and then the magnetic super-strong magnet is placed near the intrusion alarm device/unit, so that the opening and closing mechanism When it is opened, although the magnet is already away from the reed switch, the above-mentioned super-strong magnet can replace the magnet so that the metal pieces in the reed switch are still attracted to each other and remain in a fitted state, so that the alarm will not be triggered, resulting in a serious leakage alarm event. .

In view of this, embodiments of the present invention disclose an intrusion alarm device that is less susceptible to magnetic field interference.

1 shows a structure of the above-described intrusion alarm device 101, including a transceiver unit 102 that transmits and receives electromagnetic waves or mechanical waves and is disposed on an opening and closing mechanism (not shown in FIG. 1), and is connected to the transceiver unit 102 for detection. a unit 103, and an alarm unit 104 connected to the detecting unit 103. When the detecting unit 103 detects that an abnormality occurs in the receiving or receiving unit 102, the indication unit 103 The police unit 104 performs 4 alarms.

The detecting unit 103 and/or the alarm unit 104 may be disposed on the opening and closing mechanism, or may be disposed elsewhere, and communicate with the transceiver unit 102 in a wireless manner. For example, the transceiver unit 102, the detecting unit 103, and the alarm unit 104 can be designed and installed on a circuit board and placed in the casing of the intrusion alarm device 101. The transceiver unit 102 and the detecting unit 103 can also be configured as a wireless transmitting unit to enable an alarm. The unit 104 constitutes a wireless receiving unit, so that the intrusion alarm device 101 includes a matching wireless transmitting unit and a wireless receiving unit, in such a manner that the transceiver unit 102 and the detecting unit 103 are designed to be mounted on a circuit board, and the detecting unit 103 and the alarm are provided. Wireless communication is provided between units 104. In addition, in order to protect the transceiver unit 102 from being maliciously damaged, the transceiver unit 102 can be placed inside the opening and closing mechanism. At this time, the transmitting port and the receiving port need to be left outside the opening and closing mechanism to realize the transmission and reception of electromagnetic waves or mechanical waves. .

It can be seen that the intrusion alarm device is mainly composed of a transceiver unit for receiving and transmitting electromagnetic waves or mechanical waves, a detecting unit and an alarm unit, and the detecting unit instructs the alarm unit to perform an alarm when detecting that an abnormality occurs in the receiving or receiving unit of the transceiver unit. Since the intrusion alarm device in the embodiment of the present invention detects whether or not the alarm is caused by whether or not the component is magnetized, thereby causing it to be picked up or separated, it is less susceptible to the magnetic field.

The transceiver unit can transmit and receive electromagnetic waves or mechanical waves uninterrupted. Of course, in order to save power, it can also be designed to be received and received at predetermined intervals. In another embodiment of the present invention, the control unit may be used to control the time interval at which the transceiver unit transmits electromagnetic waves or mechanical waves to achieve the purpose of receiving electromagnetic waves or mechanical waves uninterrupted or at predetermined intervals. In addition, different time intervals can be set according to the season, day and night, and different application scenarios. For example, the control unit controls the transceiver unit to transmit electromagnetic waves or mechanical waves at different time intervals during the day when no one is present. In the specific implementation, the fluctuation switch can be used to realize the function of the control unit, so that the transceiver unit can work once every certain time (such as 50m seconds, 300m seconds, 2 seconds, etc.), and the transceiver unit is in a sleep state at other times. Reduce power consumption.

The opening and closing mechanism generally includes a fixed portion and a movable portion that moves relative to the fixed portion. In another embodiment of the present invention, the transceiver unit may be disposed on any one of the fixed portion and the movable portion.

Referring to FIG. 2, the transceiver unit 102 may include a transmitting unit 201 and a receiving unit 202 corresponding to the transmitting unit 201. Can be set in any one of the fixed part and the movable part of the opening and closing mechanism The transmitting unit 201 is disposed, and the receiving unit 202 is disposed on the other, or the transmitting unit 201 and the receiving unit 202 are simultaneously disposed on any one of the fixed portion and the active portion. In addition, the transmitting unit 201, the receiving unit 202, and the foregoing control unit can be used at the same time, and can be flexibly designed by those skilled in the art according to needs in a specific implementation.

In the design, the fixed state and the movable part of the opening and closing mechanism can be set to a non-alarm state, and the transceiver unit (or the transmitting unit and the receiving unit) can be set to receive electromagnetic waves or mechanical waves in this state. The status is the original state (ie, no alarm state). For example, the state in which the fixed portion and the movable portion are placed when the opening and closing mechanism is closed is set to the original state, or vice versa. When the detecting unit detects that the state of receiving or transmitting electromagnetic waves or mechanical waves of the transceiver unit (or the transmitting unit and the receiving unit) changes compared with the original state, it is considered to be in an abnormal state, and the detecting unit indicates the alarm unit to perform an alarm. In the specific implementation, the alarm unit can use the warning light to flash or the buzzer alarm to alarm, or the warning light and the buzzer can be used simultaneously, or the alarm signal can be sent to other devices/units.

It should be noted that the electromagnetic wave may be classified into radio waves, microwaves, infrared rays, visible rays, ultraviolet rays, etc. according to the frequency, and the above-mentioned mechanical waves may be sound waves (especially ultrasonic waves). For light waves, it can also be divided into ordinary light and laser. Compared with ordinary light, the laser has the characteristics of good monochromaticity, high brightness, strong directivity and strong coherence. The laser light is generally visible light and exhibits different colors depending on the wavelength, and may of course be invisible light. The transceiver unit or the transmitting unit can generate visible light or invisible light by using a light emitting diode (LED), a laser diode (LD), an infrared emitting diode, or the like.

Whether it is electromagnetic waves or mechanical waves, reflection occurs when obstacles or obstructions are encountered. Therefore, the intrusion alarm device of the present invention can realize an alarm according to the reflection principle of electromagnetic waves or mechanical waves. For example, the state in which the transceiver unit can transmit the electromagnetic wave or the mechanical wave reflected back can be set to a non-alarm state, and the state in which the transceiver unit cannot receive the reflected electromagnetic wave or mechanical wave is set to an abnormal state, and vice versa. Of course, it can also be set according to reflected electromagnetic waves or other indicators of mechanical waves, for example, designed to be the original state when the intensity of the reflected electromagnetic wave or mechanical wave meets a certain condition, and is abnormal when it does not meet the condition. Status and so on, no longer here - repeat, as long as the receiving and receiving state of the transceiver unit is preset to ensure that an abnormality occurs in receiving or receiving, the alarm unit can perform an alarm. It should be noted that for radio waves, microwaves, and sound waves (especially ultrasonic waves), the time interval between the transceiver unit or the (transmitting unit and receiving unit) can be alarmed. For example, if the opening and closing mechanism is in the non-alarm state (off), the transceiver unit (or the transmitting unit and the receiving unit) sends and receives an ultrasonic wave at a time interval of 5 ms, and in the process of opening and closing the mechanism, the transceiver unit ( Or the transmitting unit and the receiving unit may send or receive an ultrasonic wave at a time interval that may become longer or shorter, and when the time interval exceeds a predetermined range or falls within a predetermined range, an alarm may be issued.

The intrusion alarm device will be introduced in a more specific example below.

In this embodiment, referring to FIG. 3, the intrusion alarm device 300 is composed of an infrared transceiver type photoelectric tube 301, a detection circuit 302, and an alarm 303. The infrared transceiver type photo transistor 301 is further composed of a transmitting tube, a receiving tube and related circuits. The transmitting tube can be used to emit infrared rays, and the receiving tube is used for receiving infrared rays. The detecting circuit 302 can output a corresponding electrical signal according to whether an infrared ray received by the receiving tube is abnormal, and the electrical signal can be used to indicate whether the alarm 303 performs an alarm.

The electrical signal may be a switching signal. When the opening and closing mechanism is in an alarm-free state, the detecting circuit 302 does not send a switching signal to the alarm 303, and when the opening and closing mechanism is in an abnormal state and the receiving tube receives an infrared light abnormality, the detecting circuit 302 A switch signal is sent to the alarm 303 to instruct the alarm 303 to perform an alarm.

In another embodiment of the present invention, some or all of the functions of the detecting circuit 302 in the above embodiment may be implemented by a photosensor. The photoelectric sensor is a sensor that uses a photoelectric element as a detecting element, and can be used to detect a non-electric quantity that directly causes a change in the amount of light, such as light intensity, illuminance, and the like. It first converts the non-electrical quantity change of the infrared light received by the infrared transmissive photocell 301 into a change of the optical signal, and then further converts the change of the optical signal into an electrical signal change by means of the photoelectric element, and then can be indicated according to the change of the electric signal. Whether the alarm 303 performs an alarm.

Intrusion alarm devices are mostly used for doors, windows, drawers, file rejection, etc. For example, when the opening and closing mechanism is specifically a door, the fixing portion is specifically a door frame, and the movable portion is specifically a door panel. When the opening and closing mechanism is specifically a window, the fixing portion is specifically a window frame, and the movable portion is specifically a window. The door can also be divided into (toward) inside (inside the indoor side) to open the door, (to) the outer opening door and the retracting/sliding door. The intrusion alarm device will be described below with the door as an application scenario.

In this embodiment, the intrusion alarm device is mainly composed of a detection circuit, an alarm, and three sets of infrared transceiver photoelectric tubes.

For the inner door, there are two ways to make an alarm. One way is to set the infrared ray that is not received to the original state, and set the received infrared ray to the abnormal state. 4a shows the relationship between the infrared transmissive photocell 401 and the inner door opening seen in the room, and the three sets of infrared transmissive photocells 401 are arranged in a word shape on the inner side of the door frame 402 (ie, the indoor side). Above, the infrared emission direction is parallel to the closed door panel 403, so that when the inner opening door is in the closed state, the infrared transceiver type photocell 401 cannot receive the reflected infrared rays due to no obstruction in the emission direction. When the door panel 403 is opened inward, the infrared ray will be blocked by the door panel 403 and reflected, and the detecting circuit (not shown in FIG. 4) detects that the infrared transmitting and receiving photocell 401 receives the infrared ray, indicating the alarm (not shown in FIG. 4) ) to make an alarm. Another way is to set the infrared ray to the original state and the unreceived infrared ray to the abnormal state. At this time, referring to Fig. 4b, a light blocking sheet/reflecting sheet 404 can be disposed on the door panel 403, so that the light blocking sheet/reflecting sheet is opposed to the three sets of infrared transmitting and receiving photo tubes 401 when the door is closed. Thus, when the inner opening door is in the closed state, the infrared rays emitted from the infrared transmitting/receiving photocell 401 are reflected back by the blocking of the light blocking/reflecting sheet 404 in the emitting direction. When the door is opened inward, after the door panel 403 is rotated through a certain angle, there will be no obstruction in the infrared emission direction, and the infrared transmissive photocell 401 will not receive the reflected infrared rays, and the alarm can be triggered. Call the police. In addition, the number of the light blocking sheet/reflecting sheet 404 may correspond to the number of the infrared transmitting/receiving phototubes 401, and the infrared rays emitted from the plurality of sets of infrared transmitting and receiving photo tubes 401 may be used by the large-sized light blocking sheet/reflecting sheet 404. Perform reflections.

For the external door opening, it is possible to set the infrared ray to the original state and the infrared ray to the abnormal state. Fig. 5 shows the relationship between the infrared transmissive photocell 503 and the externally opened door seen in the room. Generally, the thickness of the door panel 501 of the outer door is smaller than the thickness of the door frame 502. Thus, when the door is in the closed state, the door frame 502 cannot be completely covered by the door panel 501 in the thickness direction as viewed from the inside, but an area 504 is exposed. An infrared transceiving photocell 503 can be disposed on the area 504 such that the infrared transmissive photocell 503 faces the door panel 501. The infrared ray is emitted, or the infrared transmissive photocell 503 is disposed on the door panel 501 to emit infrared rays toward the region 504. Thus, when the door is in the closed state, the infrared transmissive photocell 503 can receive the infrared ray reflected by the door panel 501 or the region 504. When the door is opened, the door panel 501 will rotate through a certain angle, and there will be no obstruction in the infrared emission direction, and the infrared transceiver photocell 503 will not receive the reflected infrared rays, and the alarm can be triggered. Call the police. This type of installation is also applicable to the retracting door, and will not be described here.

It should be noted that when the alarm mode that sets the infrared ray to the original state and the infrared ray is set to the abnormal state is set, the three sets of infrared transceiver type photocells can be set to be occluded at the same time ( When the infrared light is received, the alarm is triggered to avoid the infrared reflection caused by small animals such as reptiles in a certain group or a group of infrared transceiver photoelectric tubes, and thus the occurrence of false alarms. It can be understood that fewer sets of infrared transceiver photocells can be used in applications where there are not many reptiles.

When an alarm is set in such a manner that the infrared ray is set to the original state and the infrared ray is not set to the abnormal state, the alarm can be set as long as one or two sets of infrared transmitting and receiving optical tubes are in an abnormal state. In order to avoid the occurrence of leakage alarms caused by small animals such as reptiles always standing on a certain group or a group of infrared transceiver photocells.

When the alarm mode in which the infrared ray is set to the original state and the infrared ray is not set to the abnormal state is used, in the case where the intrusion alarm device includes the transmitting unit and the receiving unit, for the inner door opening, see FIG. 6a, The transmitting unit 601 and the receiving unit 602 are respectively disposed at opposite positions on the inner sides of the door frame 603, or referring to FIG. 6b, the transmitting unit 601 and the receiving unit 602 are respectively disposed at the relative positions of the door frame 603 and the door panel 604 (this kind) The setting method is also applicable to the retracting door), and ensures that the transmitting direction of the electromagnetic wave or mechanical wave emitted by the transmitting unit is parallel to the closed door panel 604, and the alarm function can also be realized.

It should be noted that the above embodiments are only preferred embodiments of the present invention. Based on this, those skilled in the art can design more embodiments, for example, dust-proof design of the transceiver, specifically In order to seal the infrared transceiver photoelectric tube (using transparent plastic or glass material at the light emitting part and the receiving part to ensure that light can be emitted and received). The infrared transceiver type photocell can be one or more groups, and the adjacent group of infrared transmitting and receiving lights The distance between the electric tubes is in principle larger than the length of the general reptiles, so that one reptile does not block the two sets of photo tubes at the same time, and so on.

Correspondingly, the embodiment of the present invention also discloses a security alarm system, which includes an alarm processing device and an intrusion alarm device. The alarm handling device performs alarm processing when the intrusion alarm unit alarms, such as automatically dialing a preset number or communicating with the alarm monitoring center. The intrusion alarm device may specifically be any of the intrusion alarm devices of all of the above embodiments.

Correspondingly, the embodiment of the present invention also discloses a opening and closing system which is provided with the opening and closing mechanism of all the above embodiments, and also has any one of the above embodiments.

Correspondingly, the embodiment of the present invention also discloses an intrusion alarm method for the opening and closing mechanism. Referring to FIG. 7, the method includes at least the following steps:

S71, setting an original state of transmitting and receiving electromagnetic waves or mechanical waves;

572. Detecting the sending or receiving state of electromagnetic waves or mechanical waves;

573. An alarm is issued when an abnormality occurs in the reception or transmission state of electromagnetic waves or mechanical waves. When designing, the fixed state and the movable part of the opening and closing mechanism may be set to a non-alarm state, and the state in which the electromagnetic wave or the mechanical wave is transmitted or received and received in the original state (ie, no alarm state) is set. . When an abnormality is detected in the reception or transmission state of electromagnetic waves or mechanical waves, an alarm is issued.

Whether it is electromagnetic waves or mechanical waves, reflection occurs when obstacles or obstructions are encountered. Therefore, the intrusion alarm method of the present invention can implement an alarm according to the reflection principle of electromagnetic waves or mechanical waves. For example, the state in which the reflected electromagnetic wave or mechanical wave energy is received can be set to a non-alarm state, and a state in which an electromagnetic wave or a mechanical wave cannot be received is set to an abnormal state, and vice versa. Of course, it can also be set according to reflected electromagnetic waves or other indicators of mechanical waves, for example, designed to be the original state when the intensity of the reflected electromagnetic wave or mechanical wave meets a certain condition, and is abnormal when it does not meet the condition. State, etc., no longer here - repeat, as long as the electromagnetic wave or mechanical wave receiving or receiving state is preset, to ensure that it will alarm when receiving or receiving an abnormality.

It should be noted that for radio waves, microwaves and sound waves (especially ultrasonic waves), The alarm can also be issued based on the time interval of sending and receiving. For example, if the opening and closing mechanism is in an unarmed state (closed), the time interval between sending and receiving ultrasonic waves is 5 ms, and during the opening and closing mechanism, the time interval between sending and receiving ultrasonic waves may become longer or longer. Short, when the time interval exceeds the predetermined range or falls within the predetermined range, "3⁄4 alarm" can be performed.

The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on differences from the other embodiments, and the same similar parts between the various embodiments can be referred to each other.
