When the vehicle window glass alarm device triggers an alarm, the vehicle can be triggered to double flash or whistle to send an alarm, or the ECU is triggered to send alarm information to a mobile phone of a vehicle owner, or the vehicle window glass alarm device is connected with a police service device to remind, so that the aims of warning and reminding the vehicle owner are fulfilled.

However, the conventional vehicle window glass alarm device can only detect and judge the vehicle window state based on the sensor signal, and cannot accurately reflect the current actual condition of the vehicle window, which may cause misjudgment. For example, when it rains or hails, or foreign objects fall onto the window glass, the window glass may be cracked and not broken, or only a small area may be broken, which makes theft impossible. However, the vehicle window glass alarm device still sends out a theft alarm due to the fact that the vehicle window is detected to vibrate through the sensor or the vehicle window glass is damaged, so that a vehicle owner or other related personnel make misjudgment on the current actual condition of the vehicle window when receiving the theft alarm information, and therefore excessive reaction and decision are made. Some of the prior art adopt an infrared detection image technology, and a camera installed in a car records real-time infrared photos or images of all car windows and transmits the images to a mobile phone of a car owner.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the following embodiments and the accompanying drawings.

A first embodiment of the present invention provides a window glass assembly comprising a window glass 1 and a connector 2. As shown in fig. 1, the window glass 1 includes an inner sheet of glass 101, an outer sheet of glass 102, and a transparent conductive film layer 103 sandwiched between the inner sheet of glass 101 and the outer sheet of glass 102.

The transparent conductive film layer 103 is provided with a plurality of conductive wires, and the conductive wires are insulated from each other, as shown in fig. 2 and 4, a part of the conductive wires are arranged at equal intervals in the transverse direction, and the other part of the conductive wires are arranged at equal intervals in the longitudinal direction. In fig. 2 and 4, 104 denotes vertically arranged conductive lines, and 105 denotes horizontally arranged conductive lines. The transversely arranged wires and the longitudinally arranged wires are mutually crossed to form a plurality of rectangular areas and a plurality of cross points.

The connector 2 includes a plurality of connection ends, each connection end corresponds to each wire one-to-one, and each wire is connected with the connection end that corresponds separately respectively, can insert the power in order to switch on from the connection end that corresponds separately. Each wire can be respectively connected with the corresponding connecting end through a flat cable.

The spacing between the conductors arranged in the transverse direction may be equal to or different from the spacing between the conductors arranged in the longitudinal direction.

As shown in fig. 3, in order to facilitate the connection of both ends of each wire to the connector 2, each wire may be bent or folded into a U shape (or a U-like shape), and the two bent or folded pieces are as close as possible but not electrically connected to each other. The gap between the two sections of each U-shaped wire in fig. 3 is large, so that the two sections are close to each other in practice for convenience of explaining the structure of the U-shaped wire. Thus, both ends of each wire arranged transversely are positioned on the same side, and both ends of each wire arranged longitudinally are positioned on the same side. The two ends of each conducting wire which can be arranged transversely are positioned at the bottom of the window glass 1, the two ends of each conducting wire which is arranged longitudinally are positioned at the left side or the right side of the window glass 1, the connector 2 is positioned below the bottom of the window glass 1, the two ends of each conducting wire which is arranged longitudinally are connected to the connector 2 through one flat cable, and the two ends of each conducting wire which is arranged transversely are connected to the connector 2 through the other flat cable. This facilitates the mounting of the glazing assembly to a window of an automobile.

Given the above window glass assembly, a second embodiment of the present invention provides a window glass breakage monitoring system. As shown in fig. 5, the system includes an electronic control unit 4, a main machine 6, and the above window glass assembly.

And the electronic control unit 4 is connected with each connecting end of the connector 2 of the window glass assembly, leads corresponding to the connecting ends respectively form a loop, and is used for electrifying the leads corresponding to the connecting ends through the connecting ends to detect whether the leads are conducted or not, judging whether the window glass 1 in the window glass assembly is damaged or not according to the conducting condition of the leads, positioning the damaged area of the window glass 1 when the window glass 1 is judged to be damaged, and calculating the area of the damaged area by combining the space between the leads which are transversely arranged and the space between the leads which are longitudinally arranged. If the window glass 1 is not damaged, the wires in the transparent conductive film layer 103 of the window glass 1 will not be broken, and at this time, the wires can be conducted only by electrifying the connecting ends on the connector 2. If a certain wire is not conducted after the connection ends on the connector 2 are electrified, the wire is broken, the fact that the wire breaks on a path on the window glass 1, the broken area of the window glass 1 can be located according to the transverse position of the broken wire in the transversely arranged wires and the longitudinal position of the broken wire in the longitudinally arranged wires, and the area of the broken area is calculated by combining the distance between the transversely arranged wires and the distance between the longitudinally arranged wires.

And the host 6 is connected with the electronic control unit 4 and is used for receiving the positioning and area information of the damaged area from the electronic control unit 4 and sending the positioning and area information of the damaged area to a preset receiving end 7, such as a mobile phone of a vehicle owner. An application program can also be installed on the mobile phone of the vehicle owner, and the positioning and area information of the damaged area can be received through the application program.

When the damaged area is located, the electronic control unit 4 sets two conducting wires closest to the non-conducting wires arranged in the transverse direction among the wires arranged in the transverse direction as the transverse boundary of the damaged area, sets two conducting wires closest to the non-conducting wires arranged in the longitudinal direction among the wires arranged in the longitudinal direction as the longitudinal boundary of the damaged area, and determines a rectangular area surrounded by the four conducting wires as the damaged area.

When the damaged region of the window glass 1 is positioned and the area of the damaged region is calculated, the area is calculated according to the maximum region where damage is possible. For example, as shown in fig. 2, the actual damaged area is an area 106 indicated by a dashed box in the figure, and the area passes through 6 wires of x7, x8, x9, x10, x11 and x12 which are transversely arranged and 7 wires of y5, y6, y7, y8, y9, y10 and y11 which are longitudinally arranged, and since the area is damaged, the 13 wires are not possible to be conducted (because of being broken). Then, in the case where there are and only these 13 conductive lines which are not conductive, the largest region which may be broken in the case where there are and only these 13 conductive lines which are not conductive should be taken as a broken region when the broken region is located and the area of the broken region is calculated. The largest area 107 that may be damaged at this time is a rectangular area defined by two conducting wires x6 and x13 closest to 6 non-conducting wires x7, x8, x9, x10, x11 and x12 in the laterally arranged wires and two conducting wires y4 and y12 closest to 7 non-conducting wires y5, y6, y7, y8, y9, y10 and y11 in the longitudinally arranged wires, that is, a rectangular area defined by the wires x6, x13, y4 and y12 together is the damaged area at this time, the wires x6 and x13 are transverse boundaries of the damaged area, and the wires y4 and y12 are longitudinal boundaries of the damaged area. And so on for other cases.

According to the damaged area located by the principle of the "maximum area possible to be damaged", an area calculation formula of the damaged area is obtained as s ═ m +1) x × (n +1) y, where s is the area of the damaged area, m is the number of the non-conductive wires arranged in the transverse direction, x is the distance between the wires arranged in the transverse direction, n is the number of the non-conductive wires arranged in the longitudinal direction, and y is the distance between the wires arranged in the longitudinal direction. For example, in fig. 2, the area s of the damaged region is (6+1) x (7+1) y 7x +8 y. The area calculation formula for the damaged area described above can also be used for another damaged condition shown in fig. 4. In fig. 4, since no longitudinally arranged wires are broken, each longitudinally arranged wire can be conducted, and only the transversely arranged wires x8 and x9 are broken and cannot be conducted, only the transverse boundaries of the damaged area, i.e., the wires x8 and x9, can be located at this time, but the longitudinal boundaries of the damaged area cannot be located, the actual damaged area 106 may be between any adjacent two of the longitudinally arranged wires, and the longitudinal boundaries of the damaged area may be any adjacent two of the longitudinally arranged wires, so that the damaged area cannot be specifically located. For example, the broken region in this case may be a rectangular region surrounded by the conductive lines x8, x9, y4, and y5 in fig. 4, or may be a rectangular region surrounded by the conductive lines x8, x9, y6, and y 7. Although the position of the damaged region cannot be specified, the area s of the damaged region (i.e., the maximum region 107 where damage is possible) at this time can be calculated to be (2+1) x (0+1) y or 3x + y.

The window glass breakage monitoring system can be installed on an automobile, and the electronic control unit 4 is connected with a central control door lock 5 of the automobile. The electronic control unit 4 is further configured to lock each door lock 8 of the automobile from inside and outside through the central control door lock 5 after receiving a locking instruction sent by the receiving terminal 7, and to power off each door lock 8. When the power is turned off after the door lock 8 is locked from both inside and outside, the door cannot be opened from either the inside or the outside of the door, and thus a thief cannot open the door from the inside of the door after breaking the window glass 1.

The electronic control unit 4 is also used for receiving a locking signal of the automobile in real time, and when the locking signal of the automobile is received, the window glass breakage monitoring system is started. This is done primarily to avoid the window glass breakage monitoring function being activated when the owner is inside the vehicle. Because it is not necessary for the vehicle owner to activate the window glass breakage monitoring function while inside the vehicle. Furthermore, if start window glass breakage monitoring function when the car owner is located the car, when taking place danger and need the car owner in time to shift to the car outside, if the door window has been broken just this moment, lead to each door lock 8 from inside and outside all locking, and all can't open from inside and outside the car, cause harm to car owner safety on the contrary. The car owner can send out the locking signal through intelligent car key 3 when leaving its car, and this locking signal is relayed after being received by the start-up system of car to electronic control unit 4, and electronic control unit 4 locks the car and starts window glass breakage monitoring system after receiving this locking signal.

A third embodiment of the invention provides an automobile comprising a window glass breakage monitoring system as above; a window glass assembly is mounted on at least one window of the vehicle.

The above-described embodiments are merely preferred embodiments, which are not intended to limit the scope of the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
