Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to an alarm device, as shown in fig. 1, including: alarm, theftproof wire, electric measurement module and processing chip. The electric measurement module is used for obtaining the electric parameters of the anti-theft lead and is electrically connected with the processing chip. In addition, the processing chip is electrically connected with the alarm and is used for triggering the alarm when the change of the electrical parameter value obtained by the electrical measurement module accords with a preset rule.
Specifically, the electrical parameter in this embodiment is a resistance, that is, the processing chip determines whether the alarm needs to be set off according to whether the obtained change in the resistance value meets a preset rule.
More specifically, in the embodiment, the electrical measurement module and the anti-theft wire form a structure similar to a wheatstone bridge (i.e. a single-arm bridge), and as shown in fig. 2, the electrical measurement module specifically includes: a current measurement device (such as ampere meter) for measuring current direction and current intensity, current measurement device with handle chip electric connection, electric measurement module still includes: a first resistor R1, a second resistor R2, and a third resistor R3. The first end a of the first resistor R1 is connected with the first end a of the third resistor R3, the second end b of the first resistor R1 is connected with the first end b of the second resistor R2, the first end c of the antitheft wire is connected with the second end c of the second resistor R2, the second end d of the antitheft wire is connected with the second end d of the third resistor R3, the current measuring device is connected between the second end of the first resistor R1 and the second end of the antitheft wire, and the first end of the first resistor R1 and the second end of the second resistor R2 are connected with a power supply.
In the structure of the electric measurement module and the anti-theft wire, the anti-theft net body (namely the anti-theft wire) is equivalent to a resistor and is recorded as the R wire, at the moment, if a thief short-circuits the wire to the anti-theft wire or cuts off the anti-theft wire, the resistance value of the R wire is changed, then current passes through the ammeter, and the pointer of the ammeter deviates leftwards or rightwards according to the current direction at the moment, so that the R wire is determined to be enlarged or reduced.
Further, in the present embodiment, the change process of the electrical parameter value may be defined as first decreasing and then increasing, that is, the change of the electrical parameter value conforms to a preset rule including first decreasing and then increasing. When the anti-theft lead is in short circuit by the lead, namely, two ends of the R lead are connected with one lead in parallel, the change of the resistance value between the cd ends can be caused, the resistance of the newly added lead in practical application is smaller than that of the R lead, so the resistance change between the cd ends is generally reduced, and then if the anti-theft lead is cut off, the change of the resistance value can be in a state of being enlarged again, so the change of the resistance value is judged by utilizing the change trend of being firstly reduced and then enlarged, the judgment result is more in line with the circuit reality, and the alarm is more accurate.
As a further optimization, the third resistor R3 may be a variable resistor (e.g., a sliding rheostat), the third resistor R3 is electrically connected to the processing chip, and the processing chip is further configured to adjust the resistance of the third resistor R3 according to the measurement value of the current measurement device, and adjust the initial current measured by the current measurement device by adjusting the resistance of the third resistor R3, and may also be used for circuit zeroing, so that in an initial state, R1R lead R3R 2 is achieved, that is, no current passes through the current meter at this time, and the meter needle is in the middle, so that the subsequent change determination is simpler and more accurate.
In practical application, the processing chip can be a microchip, when the parallel connection condition occurs on the circuit, the current measuring device can detect the current change, once the current value changes, whether the resistance of the anti-theft wire changes can be further determined, and the microchip controls the alarm to give an alarm when the change is judged to meet the preset condition.
Specifically, meeting the preset condition may further include: a change in the measured electrical parameter value; or the measured electric parameter value changes, and the difference value before and after the change exceeds a first preset value; alternatively, the measured value of the electrical parameter varies by an amount exceeding a second preset value. That is, it may be set to alarm as long as a change occurs, or it may be set to alarm when a change difference exceeds a first preset value, or it may be set to alarm when a change amount exceeds a second preset value, and each preset value may be determined by experience of a designer, and will not be described herein again.
The change of the physical quantity is measured by using the change of the resistance, the change of the corresponding electrical parameter can be calculated by the microchip collecting and processing the change of the current, the measuring method is a measuring mode with high precision, and the change condition of the electrical parameter of the anti-theft lead can be very simply and accurately measured by using the device.
It should be noted that the anti-theft wire in this embodiment may specifically include a plurality of (i.e., one or more) wires arranged in a mesh shape, and the wire is specifically a steel wire rope wire, which is relatively firm and not easy to be cut, and can play a good anti-theft role. Of course, the wire of the anti-theft wire can also be a nylon anti-pulling wire, and the nylon anti-pulling wire has small deformation when being pulled and is easy to be cut off. When a fire disaster occurs, the alarm circuit formed by the nylon anti-pulling wires can be cut off for escape, and after the alarm circuit is cut off, the alarm device gives an alarm, so that the alarm can be dealt with in a very simple mode. In practical application, other different wires can be selected according to different application scenes, so that the practical requirements of users are met.
In addition, it is worth mentioning that if the alarm, the electric measurement module and the processing chip are installed separately, the installation of the alarm device is troublesome, and in practical application, the alarm, the electric measurement module and the processing chip can be integrated in a shell, so that a user can install and use the alarm device conveniently.
Compared with the prior art, the electric measurement module capable of measuring the electric parameters of the anti-theft conducting wire is added in the alarm device, and once the measured electric parameter value of the anti-theft conducting wire is not consistent with the preset rule, the alarm can be triggered. The inventor of the invention changes the existing detection principle, namely, the invention detects the electrical parameter of the anti-theft wire, even if the passage exists, the condition that the electrical parameter changes due to the parallel connection of another wire or the cutting of the anti-theft wire can be caused, so that the state of the anti-theft wire can be accurately known, and whether the anti-theft wire is cut off or not can be determined. Therefore, the alarm device and the anti-theft device in the embodiment can determine whether the anti-theft wire is damaged or not by detecting the change of the electrical parameter of the anti-theft wire, so that the anti-theft wire in the alarm device can still give an alarm even if being cut off under the condition of short circuit, the reliability is greatly improved, and the safety of the alarm device is also improved.
It should be noted that the electrical parameter detected in the present embodiment is a resistance, but in practical applications, the electrical parameter may be a current or a voltage, or may be determined jointly according to a plurality of electrical parameters, which are not listed here.
The second embodiment of the invention also relates to an alarm device, which is the same as the first embodiment, and mainly has the difference that the electric measuring module in the first embodiment comprises a series of resistors, each resistor and the anti-theft lead form a single-arm bridge, so that the current measuring device is used for measuring, and the anti-theft lead is measured by using a multimeter in the embodiment, so that the method is simpler, more convenient and lower in cost.
The embodiment takes the electrical parameter to be measured as an example of the resistance, specifically speaking, the universal meter can be connected to two ends of the anti-theft wire, the measured resistance is sent to the memory, the memory can be a memory in the universal meter or a memory of the processing chip, the processing chip compares the resistance value, whether the change occurs can be judged, and the alarm is triggered when the change occurs conforms to the preset rule.
Further, the recorded resistance value may be timed by using a timer, and the resistance value of the preset time difference may be compared, where the preset time difference may be set to 1 second, that is, whether the resistance value measured at an interval of 1 second changes or not may be compared.
It should be noted that, the inventor of the present application thinks that the burglar mesh may be short-circuited by a lawless person in advance, so the preset rule may be that the resistance value is first reduced and then increased, so that the burglar mesh is also changed when short-circuited, which is more convenient for the judgment of the actual situation, and the alarm is prevented from being missed.
Therefore, the embodiment adopts the universal meter to measure the resistance of the anti-theft wire, so that the implementation is simpler and more convenient, the cost is low, in addition, the universal meter is used for measuring the resistance of the anti-theft wire, and other electrical parameters of the anti-theft wire, such as current and the like, can be measured, and are not listed one by one.
A third embodiment of the present invention relates to an alarm device, and the third embodiment is a further improvement on the alarm device of the first embodiment, and the main improvements are that: in a third embodiment, as shown in fig. 3, the alarm device further includes a communication device electrically connected to the processing chip, and the processing chip is further configured to send alarm information to a pre-designated terminal device through the communication device when the electrical parameter measured by the electrical measurement module is different from the preset value, so that a user can remotely know that the alarm device alarms even if the user is not at an alarm site.
Therefore, in this embodiment, the alarm device is further provided with a communication device, the communication device can send alarm information to a specified terminal device, and the terminal device can be a mobile phone or a computer. When the anti-theft wire is cut off, the processing chip simultaneously controls the alarm to give an alarm and controls the communication device to send alarm information to the mobile phone or the computer to send information, and a user can obtain the information at the first time.
Even if the alarm device is in short circuit, the anti-theft wire can still give an alarm when being cut off, so that the reliability of the alarm device is greatly enhanced, and the alarm device can send alarm information to a user who is not on an alarm site, so that the user can obtain information in the first time.
A fourth embodiment of the present invention relates to an antitheft device including the alarm device as in any one of the first to third embodiments. The alarm device that sets up on this anti-theft device includes: alarm, theftproof wire, electric measurement module, processing chip and communication device.

In addition, handle chip respectively with alarm, communication device electric connection for electric parameter that the module surveyed at the electricity measures triggers the alarm and sends alarm information to the terminal equipment appointed in advance through communication device simultaneously when different with the default.
Specifically, the anti-theft wire can be continuously bent to be arranged on the anti-theft equipment in an S shape and is fully distributed on the window of the anti-theft equipment, so that people outside the anti-theft equipment cannot enter the anti-theft equipment from the inside of the anti-theft equipment under the condition of not damaging the anti-theft wire, and the safety performance of the anti-theft equipment is ensured. Of course, in order to meet different application scenarios, the antitheft wires can also be arranged on the antitheft device in a grid shape, so that the safety is higher, and the requirement on wiring is correspondingly higher. When the anti-theft wire of the anti-theft device is cut off, the processing chip simultaneously controls the alarm to give an alarm and controls the communication device to send alarm information to the mobile phone or the computer, and a user can obtain the information at the first time.
Even if the alarm device of the anti-theft device is in short circuit, the anti-theft wire can still give an alarm when being cut off, and the safety of the anti-theft device is greatly enhanced.
