New description: [New technical field] This creation is about a monitoring system (m〇nit〇ring system), and especially related to an applied piezoelectric effect (piez 〇dectric effect) monitoring system. [Prior Art] With the popularization of technology, the monitoring system installed in general construction for theft prevention is becoming more mature. The conventional monitoring system usually includes a plurality of monitoring cameras, a monitoring host (monit〇ring h〇st), and a monitor module (4), wherein the monitoring host is electrically connected to the monitoring camera and the monitor. The surveillance camera converts the image it monitors into an image signal and transmits it to the monitoring host: enabling the monitor to display the image monitored by the surveillance camera. In this way, guards or security service personnel can monitor multiple public spaces inside and outside the building through the control system. However, the surveillance camera has a certain volume, which is easily seen by thieves, and the hidden corners that are not monitored by the camera can invade the building, or cover the camera lens with a concealer. In addition, in order to take into account personal privacy, there are some places in Building 1 that are not suitable for installing surveillance cameras, such as homes, corridors, and office rooms. These are not suitable for surveillance cameras. This will give thieves a chance to invade the building. And form a security loophole. =Outside: The monitoring system that uses the surveillance camera must monitor the building by guarding or maintaining the monitor. Once the guard or security personnel have not seen it, the thief will be stunned. Although through the conventional monitoring system: can watch the video, video recording media to watch the appearance, characteristics or crimes of the thief M316455 IAC060211 .TW 22435twf.doc/n, but the thieves can wear special clothing A mask or helmet is used to cover the appearance. Another type of monitoring system is based on the principle of infrared scanning. When a thief invades a building, his body _ has a body temperature and emits a red line. This type of supervision (4) is to measure the infrared light in a specific place. Once the intensity of the infrared light sensed by the infrared sensor exceeds a certain value, there is no thief intrusion, and the monitoring system will issue an alarm. . However, as long as the thieves have the equipment and technology, it is not a problem to avoid the monitoring of such monitoring systems. For example, thieves can wear clothing that blocks infrared rays' from being detected by such surveillance systems, or thieves can invade buildings from outside the sensing range of the infrared sensor. In addition, this monitoring system can cause false positives. For example, when a pet or other small animal passes through the sensing range of the infrared sensor, the infrared rays emitted by the pet or other small animals easily cause the monitoring system to misjudge the thief intrusion here. . [New content] This creation provides a monitoring system with features of privacy, high sensitivity and low false positive rate. The present invention proposes a monitoring system for monitoring a building, the monitoring system comprising a piezoelectric sensing module (piez〇electric sensing brain (6), a warning generator and a monitoring device (m〇nit) The 电感ring device includes a plurality of piezoelectric sensors (sensors) disposed under the surface of one of the structures and adapted to sense one of the weights of the surface of the building. The alert generator is used to generate a warning. The monitoring device is electrically connected to the voltage sensor and the alarm generator. M316455 IAC060211.TW 22435twf.doc/n § The device judges the weight according to the signal from the pressure sensor. The default range is In the meantime, the monitoring device will instruct the police to generate a crying and a warning. " In one embodiment of the present invention, the piezoelectric inductors can be arranged in an array below the surface of the building. In an embodiment of the present invention, the monitoring device may include a computer. In an embodiment of the present invention, the monitoring device may further include a signal according to a signal transmitted from a pressure sensitive inductor. A pressed position on the surface of the building. In one embodiment of the present invention, the monitoring device may further comprise determining a time of compression of the surface of the building based on a signal from a pressure sensor that is subjected to weight. In one embodiment of the present invention, the alert generator can include a signal emitting apparatus to transmit the alert to a terminal apparatus. In the conventional embodiment of the present invention, the signal transmitting device may be a network signal emitting device adapted to transmit an alert to the terminal device via the Internet. In an embodiment of the present invention, the signal transmitting device can be a wireless signal transmitting device adapted to transmit the alert to the terminal device in a wireless transmission manner. In an embodiment of the present invention, the signal transmitting device can be a telephone signal transmitting device adapted to send the alert to the terminal via the telephone network M316455 IAC060211 .TW 22435twf.doc/n (telephone network) Device. Since people on the earth are attracted by gravity, if the thief enters the building and steals, its own weight needs to be supported by the surface of the building. Therefore, the monitoring system of the present invention uses the pressure inductance detector disposed under the surface of the building to sense the weight of the thief, which makes it difficult for the thief to monitor the monitoring system of the county. In addition, since the piezoelectric inductive detector buried under the surface of the building is extremely undetected, the monitoring system of the present creation

In order to make the above and other objects, features and gamma of the present invention more obvious, the preferred embodiments are described below in detail, and are described in detail below. [Embodiment] Δ FIG. 1 is a schematic structural diagram of a monitoring system according to the present invention. Referring to FIG. 1, the monitoring system (10) of the present embodiment is used for monitoring and building. The monitoring system 100 includes a piezoelectric sensing module 11A, a monitoring device (10) = a warning generating 11 13G. The pressure sensing module no includes a plurality of pressure inductors: two, 2; battle; below the surface of the object, and is suitable for sensing the surface of the building f t and reset. The surface of the structure here is, for example, a floor, a carpet, a flat door, and any other object suitable for bearing weight on the surface of the building. The monitoring electric I/he is connected to the voltage detector 112 and the alarm generator 13A. When the signal transmitted by the sensor 112 determines that the building is in the preset range of the device 12G, the monitoring device 120 generates a warning by the private alarm generator 130. Since people on the earth are bound to be attracted by gravity, the thief M316455 IAC060211 .TW 22435twf.doc/n The thief entering the building must support its own weight by the surface of the building. The weight of the thief will cause the pressure sensor Π2 located below the surface of the building to be pressurized to generate a signal to the monitoring device 120. When the weight of the thief (ie the weight of the surface of the building) is set at the preset value of the monitoring device 12 In the above (for example, 40 kg), the monitoring device 12 will judge the thief to invade and instruct the alarm generator 130 to generate a warning. Therefore, the monitoring system 100 of the present embodiment senses the weight of the thief by using the pressure sensor n2 disposed under the surface of the building, which makes it difficult for the thief to avoid the monitoring of the monitoring system. In addition, since the piezoelectric detector 112 buried under the surface of the building is extremely difficult to be seen, the monitoring system 1〇() of the present embodiment is also difficult to find a cracking method. Furthermore, the user of the monitoring system 1() can adjust the above-mentioned pre-range to avoid that the pet or other small animals in the building pass through the surface of the building, and the monitoring system 100 misjudges the thief to invade, thus effectively reducing the monitoring system. 100 false positive rate. For example, when the preset range is set to be greater than 40 kg, a small animal weighing 5 kg is not sufficient to cause the monitoring system 100 to judge that there is a thief intrusion. Of course, the monitoring system (10) can be turned on when needed. For example, when the user is located in the building, the monitoring system 100 can be turned off to prevent the alarm generator 130 from generating a three-degree delay. The monitoring system 10() is turned on when the user leaves the building. . In the case of the example, the piezoelectric inductors 112 can be arranged in an array below the pressure to average the pressure from the surface of the building. In addition, the I2G can include a computer to process the pressure sensor 112. For example, the monitoring device 120 can judge the pressure of the surface of the building according to the signal transmitted by the pressure inductor 112 that receives the weight. Position, M316455 IAC060211.TW 22435twf.doc/n For example, each voltage sensor 112 is sequentially given a number, and an area can be correspondingly generated according to the number of the signal source to know the pressure position, and the monitoring device 120 The pressure time of the surface of the building may also be judged according to the signal transmitted from the pressure sensor 112 subjected to the weight, such as the time point of pressure or the time elapsed after continuous pressure. In the present embodiment, the alert generator 130 can include a signal transmitting device to send the alert to a terminal device for the user to install the alert through the terminal. For example, the 'signal transmitting device can be a network signal transmitting device that can send an alert to the terminal device via the Internet; = ^ the transmitting device can also be a wireless signal transmitting device that is adapted to transmit The alert is sent to the terminal device; or the signal transmitting device can be a -phone!wei transmitting device adapted to pass the f to the terminal device.

The generator 13 can also include an alarm, and the alarm can be a slam. Thus, when the monitoring device 12 touches a thief, it can immediately indicate that the alarm is not sounding to deter the thief. In this embodiment, the piezoelectric detector 112 utilizes a piezoelectric material (piezoelectric m) The piezoelectric effect of aterial) produces a signal. When a piezoelectric material is subjected to an external force in a certain direction, a polarization phenomenon is generated inside, and accordingly, a positive and a negative electric charge is generated on both surfaces of the piezoelectric material; When removed, the piezoelectric material returns to the uncharged state. When the external force changes direction, the polarity of the charge changes. This phenomenon is called the piezoelectric effect. There are many piezoelectric materials with piezoelectric effect, for example Quartz crystal, piez〇eiectric cemmic materiai, C% semiconductor (piezoeiectric semic〇nduct〇r), etc. The following quartz crystal is taken as an example, and the piezoelectric effect is explained in detail with a pattern. 2A shows the state of the quartz crystal when it is not subjected to an external force, FIG. 2B shows the charged state of the surface of the quartz crystal when subjected to the X direction pressure, and FIG. 2C shows the surface of the quartz crystal when it is pressed by the Y direction. The charged state. Please refer to Figure 2a to Figure 2C. Quartz crystal 2〇〇 is a widely used piezoelectric crystal. It is a silicon dioxide single crystal and belongs to hexagonal crystal. It is a hexagonal cylinder whose shape is regular. The quartz crystal 200 has three crystal axes of X axis, γ axis and 2 axes perpendicular to each other. The Z axis is also called the optical axis, and it is combined with M316455 IAC060211.TW 22435twf.doc/n The direction of the longitudinal axis of the crystal (such as the direction of the vertical plane) is the same. The X-axis is also called the electric axis. It is perpendicular to the Z-axis and passes through two ridgelines opposite the hexagonal column. γ is also called the mechanical axis, which is related to the Z-axis and x. The axis is perpendicular and perpendicular to the two facets of the hexagonal column phase. In each crystal unit of 20 〇, there are three strontium ions and one oxygen ion. The distribution of positive and negative ions on the apex angle of the regular hexagonal column is shown in Fig. 2A, in which the negative ions are 21 〇, 23 〇, 2 乂 and the positive ions are fine, and the ions are cut. When the quartz crystal m is subjected to an external force, as shown in Fig. 2A, the positive and negative charges are balanced with each other, so there is no charging phenomenon outside the hair. /, 菖 When the force is applied to the Shiyang crystal 200 in the X-axis direction, as shown in Fig. 2B, the negative ion 21〇 will be squeezed into the positive ion 22〇 and the positive male 240 will be squeezed into the negative ions 230 and 250. Between, the surface 27〇^ appears a positive charge, and a negative charge appears on the surface. If the polarity of the charge appearing on the surface 270 and the surface 280 is applied to the quartz crystal 200 on the x-axis side + (i.e., opposite to the direction of the pressure Fx) 4', the force FX is reversed. A rich applies pressure to the dendrite crystal 200 in the Y-axis direction; if ργ, then the polarity of the charge present on the surface 270 and the surface 280 is as shown in Fig. 2C. When a tensile force is applied to the quartz crystal 200 in the direction of the yaw axis, the polarity of the electric charge appearing on the surface 270 phase " 280 is the same as the case where the pressure 匕 is applied, and the piezoelectric material is subjected to pressure in the photo. When the surface accumulates the packet, the voltage sensor 112 can generate a corresponding signal to be transmitted to the control unit 120. In addition, the greater the pressure on the material, the more charge is accumulated on the surface, resulting in stronger signal strength generated by the voltage detector 112. . In this way, the monitoring device 12 can convert the pressure received by the piezoelectric detector m according to the intensity of the signal transmitted from the piezoelectric sensor, and further change the weight of the surface of the building. • In summary, since people on the earth are bound to be attracted by gravity, theft and entry into the building must be controlled by the surface of the building. The monitoring system uses a pressure sensor placed below the surface of the building to sense the weight of the thief, making it difficult for thieves to use - any method to avoid the monitoring of the monitoring system of the creation. In addition, since the piezoelectric inductance detector buried under the surface of the building is extremely difficult to be seen, the monitoring system of this creation is also difficult to find a solution. Furthermore, the user of the creation monitoring system can adjust the weight preset range that will generate the alarm to effectively and low the false positive rate of the monitoring system. In addition, since the monitoring system of the present invention can transmit the alarm to the remote terminal device by its alarm generator, the user can receive the alarm anywhere to achieve the real-time monitoring of the building. Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application.
