Embodiment
At first please refer to Fig. 1, the warning system 100 of one embodiment of the invention mainly comprises transparent pressure sensor 110, a processing unit 120 and a warning horn 130.Aforementioned pressure sensor 110 for example is a pressure resistance type pressure sensor (Piezoresistive Pressure Sensor); It has pliability and is coated in the surperficial S1 of an object G (for example glass window surface); 120 of aforementioned processing unit are electrically connected pressure sensor 110 and warning horn 130, and above-mentioned warning horn 130 for example is a hummer (buzzer).
When object G receives external force collision; Pressure sensor 110 can change because of the stressed internal resistance value that causes; This moment, impact parameter signal a to processing unit 120 was transmitted in pressure sensor 110 meetings; Then processing unit 120 just can judge whether to see off alarm signal to the warning horn 130 of a correspondence according to this impact parameter signal, uses driving warning horn 130 and gives the alarm.Will be appreciated that aforementioned pressure sensor 110 can transmit this impact parameter signal to processing unit 120 through transfer wire or with Wireless transmission mode; In like manner, aforementioned processing unit 120 also can transmit this alarm signal to warning horn 130 through transfer wire or with Wireless transmission mode.
Please continue with reference to figure 1, object G in the present embodiment can be one or window, and 110 of aforementioned pressure sensors are flat and are attached on the surperficial S1 of object G.Will be appreciated that; Aforementioned pressure sensor 110 includes a plurality of pressure-sensings unit 111; Wherein said pressure-sensing unit 111 is distributed on the surperficial S1 of object G with array way; But also can non-array way be distributed in object G surface S1, use the stressed situation of effective inspected object G surface S1.
As previously mentioned; When pressure sensor 110 senses door and window when suffering external force collision; Can transmit impact parameter signal a to processing unit 120; Wherein this impact parameter signal comprises the resistance value of each pressure-sensing unit 111 and lays respectively at the lip-deep position coordinate value of object G, and processing unit 120 just can be learnt the information such as intensity, impingement region shape and area size thereof of external force collision according to this impact parameter signal thus, uses decision and whether drives warning horn 130 and give the alarm.
What need special instruction is that the surperficial S1 (as Fig. 2 A shown in) of aforementioned pressure sensor 110 except being arranged at object G also can be arranged on another the surperficial S2 (shown in Fig. 2 B) in contrast to surperficial S1; In other words, optionally pressure sensor 110 is coated in inboard or the outer surface of object G.Perhaps, also can be and inner surface S1, the last pressure sensor 110 (shown in Fig. 2 C) that is provided with respectively of S2 in the outside of object G, use the sensitivity that promotes sensing.In addition, also can pressure sensor 110 clampings (shown in Fig. 2 D) between the adjacently situated surfaces of two object G be damaged to avoid pressure sensor 110 to receive external force collision.In one embodiment; The material of aforementioned object G can be tempered glass, annealed glass or bullet proof glass; The area of aforementioned pressure sensor 110 can be less than surperficial S1, the S2 of object G, and perhaps the area of pressure sensor 110 also can cover surperficial S1, the S2 of object G fully.
Because the pressure sensor 110 in the present embodiment has the characteristic of transparent and flexible, therefore can not cover object G, and can be attached to widely on any object with curved surface.For example; The present invention can with transparent and the flexual pressure sensor 110 of tool be coated in that historic site, paintings or show piece etc. do not hope to be touched or frangible body surface on (as shown in Figure 3); Use effective detection external force collision or unusual vibrations, and can give the alarm in real time and stolen or destroy to prevent it.
Because the impact parameter signal that pressure sensor 110 is sent comprises the resistance value and the corresponding position coordinate value thereof of each pressure-sensing unit 111, so processing unit 120 can be learnt intensity, position and the impingement region area shape of external force collision according to this impact parameter signal.In addition; According to information such as impingement position in the impact parameter signal and bump number of times frequencies; Also can assess seriousness and the threaten degree that receives external force collision further; Wherein when suffering successional external force collision, processing unit 120 can be seen alarm signal to warning horn 130 immediately off, uses driving warning horn 130 and gives the alarm; On the contrary, of short duration or when being merely incident when the external force collision time that pressure sensor 110 is sensed, processing unit 120 records impact parameter signal and can not start warning horn 130 then, the situation that can reduce wrong report by this takes place.
For example, when this impact parameter signal continues one section special time, when perhaps the frequency in a Preset Time is greater than a specific times, processing unit 120 signal to the warning horn 130 that just can give the alarm.Another kind of situation is excessive and when causing pressure sensor 110 to be damaged when clashing into strength; Pressure sensor 110 inner meeting formation are opened circuit and are produced great resistance value; Processing unit 120 same alarm signal to the warning horns 130 that can send a correspondence according to the impact parameter signal were used driving warning horn 130 and were given the alarm this moment.
In sum; The present invention provides a kind of intelligent warning system; Wherein through transparent in a body surface coating one and have a flexual pressure sensor; Not only applicable to the object of Any shape, and can detect the information such as area, shape of the intensity, position and the impingement region that receive external force collision by this.In addition, the present invention can assess seriousness and the threaten degree that receives external force collision according to the number of times frequency of bump further, and the situation that can reduce wrong report simultaneously takes place, and then can significantly promote its functional and practicality.
Though the present invention discloses as above with aforesaid preferred embodiment, it is not in order to limit the present invention.Those skilled in the art, under the premise without departing from the spirit and scope of the present invention, when doing some changes and modification.Therefore protection scope of the present invention should be as the criterion with claim of the present invention.
