Description

Technical Field

[0001] This application relates to the field of anti-theft technology, and in particular to a monitoring system for cable anti-theft. Background Technology

[0002] During construction, cable laying methods mainly include direct burial and laying along supports and cable trays. Regardless of the method used, the cable will not be energized during laying and construction. Furthermore, one end or the entire cable is usually exposed outdoors. When the cable is long and under construction, accurate monitoring and theft prevention are impossible, creating a risk of theft. Moreover, if the cable is stolen, it needs to be repurchased and re-laid, increasing both costs and time.

[0003] Current technologies can only monitor and prevent theft on small-scale construction sites. Therefore, there is no effective solution for cable theft prevention over large areas and long distances. Summary of the Invention

[0004] Therefore, the purpose of this application is to provide a monitoring system for cable theft prevention, which has the advantage of effectively preventing cable theft.

[0005] One aspect of this application provides a monitoring system for cable theft prevention, including a cable inspection system and a warning system;

[0006] The cable inspection system includes a pulse signal generation unit, a loop fitting component, a signal receiving unit, a controller, and a wireless transmission module;

[0007] The pulse signal generating unit and the signal receiving unit are connected to the two ends of one end of the cable, respectively, and the loop fitting component is installed at the other end of the cable to form a loop; the pulse signal is emitted by the pulse signal generating unit, and is received by the loop fitting component after passing through the loop of the cable.

[0008] The controller is electrically connected to the pulse signal generating unit and the signal receiving unit respectively, and is used to control the pulse signal generating unit to emit pulse signals and to receive signals emitted by the signal receiving unit.

The pulse signal generating unit emits a pulse signal, which is received by the signal receiving unit. Each strand transmits a pulse signal back. If every strand (except the one that emitted the pulse signal) receives a returned pulse signal, the cable is considered intact and has not been stolen. If one or more strands do not return a pulse signal, the theft has occurred. When theft is detected, if the signal receiving unit does not receive a pulse signal within a set time range, it will not send a signal to the controller.

In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0059] Please see Figures 1-10 This application exemplifies a monitoring system for cable theft prevention, including a cable inspection system and a warning system;

[0060] The cable inspection system includes a pulse signal generating unit 81, a loop fitting component 10, a signal receiving unit, a controller, and a wireless transmission module;

[0061] The pulse signal generating unit 81 and the signal receiving unit are connected to the two ends of one end of the cable 90, respectively, and the loop fitting component 10 is installed at the other end of the cable 90 so that the cable forms a loop; the pulse signal is emitted by the pulse signal generating unit 81, and is received by the loop fitting component 10 after passing through the loop of the cable.

[0062] The controller is electrically connected to the pulse signal generating unit 81 and the signal receiving unit respectively, and is used to control the pulse signal generating unit to emit pulse signals and to receive signals emitted by the signal receiving unit.

[0063] The wireless transmission module is electrically connected to the controller to wirelessly transmit alarm signals issued by the controller.

[0064] The loop fitting assembly 10 includes a first clamping block 12, a second clamping block 11, a clamping spring 14, and guide rods 13. One end of each of the three guide rods 13 is threaded onto the first clamping block 12. The second clamping block 11 has three through holes, through which the three guide rods 13 pass. The other end of each guide rod 13 has a limiting abutment portion 15. The clamping spring 14 is sleeved on the guide rod 13, and both ends of the clamping spring 14 abut against the second clamping block 11 and the limiting abutment portion 15, respectively, so that the first clamping block 12 and the second clamping block 11 are clamped relative to each other.

[0065] The upper surface of the first pressing block 12 is formed with a first inclined groove 16; the lower surface of the second pressing block 11 is formed with a second inclined groove 17; when the first pressing block 12 and the second pressing block 11 are in contact, the first inclined groove 16 and the second inclined groove 17 form an intersection area.

[0066] The warning system and the controller are wirelessly connected via the wireless transmission module.

[0067] The monitoring system for cable theft prevention described in this application connects the two ends of cables during construction and installation. The cables have at least two or two strands of wire, and can even have three or five strands. One end of one strand is connected to a pulse signal generating unit 81, and the ends of the other one or more strands are connected to signal receiving units. At the other end of the cable, the ends of multiple strands are connected together by a loop fitting component 10, forming a loop. The pulse signal generating unit 81 emits a pulse signal, which is received by the signal receiving unit. Each strand transmits a pulse signal back. If every strand (except the one that emitted the pulse signal) receives the returned pulse signal, the cable is considered intact and has not been stolen. If one or more strands do not return a pulse signal, the theft has occurred. When theft is detected, if the signal receiving unit does not receive a pulse signal within a set time range, it will not send a signal to the controller. If the controller does not receive a signal from the signal receiving unit within the set time range, or if the number of signals received from the signal receiving unit is insufficient, the controller will issue a warning signal indicating that the cable has been stolen.

[0068] Regarding the method of using the loop fitting component 10, one wire from the other end of the cable is placed in the second inclined groove 17 of the second clamping block 11, and the other wires from the same end are placed in the first inclined groove 16 of the first clamping block 12, with the exposed metal portions of the wires all positioned in the intersection area. When the first clamping block 12 and the second clamping block 11 are in contact, the exposed metal portions of all the wires are compressed, thereby connecting all the wires.

[0069] It should be noted that the term "one conductor" in this application refers to all conductors wrapped in the same insulating sheath. This may consist of a single metal wire or a strand of multiple metal wires wound together, depending on the function of each conductor. Specifically, if the cable consists of a neutral wire and a live wire, then in this application, it indicates that the cable has two conductors; if the cable has three live wires, one neutral wire, and one ground wire, then in this application, it indicates that the cable has five conductors. It is not referred to as "six conductors" simply because a live wire has six metal wires; in this case, it is only referred to as "one conductor."

[0070] Furthermore, by setting the first clamping block 12 and the second clamping block 11, and clamping the first clamping block 12 and the second clamping block 11, multiple wires at the other end of the cable are connected and clamped, making it convenient and easy to form a circuit.

[0071] One end of the cable is placed near a 220V household power cable to provide power to the pulse signal generating unit 81, the signal receiving unit, the controller, and the wireless transmission module. Ideally, the power supply should be continuous and there should be no need to consider charging.

[0072] In some preferred embodiments, the pulse signal generating unit 81 is a pulse signal generator; the signal receiving unit is a signal receiver with multiple contacts 82 for receiving pulse signals; the controller can be an electronic control motherboard, a microcontroller, a PLC module, or a single-chip microcomputer and other control devices; the wireless transmission module can be a 4G communication module, a 5G communication module, a shortwave communication module, a satellite communication module, etc.

[0073] At one end of the cable, multiple contacts 82 of the signal receiving unit are connected to the wires of the loop. At the other end of the cable, the connection point 83 of the signal receiving unit is connected to all the cables.

[0074] In some preferred embodiments, a plurality of first inclined grooves 16 are formed on the upper surface of the first pressing block 12, the plurality of first inclined grooves 16 are arranged in different directions and form a common converging point; the converging point is connected to the intersection area.

[0075] Furthermore, the first inclined groove 16 and the second inclined groove 17 can be straight or curved; the intersection area of ​​the first inclined groove 16 and the second inclined groove 17 can be large enough or small enough, as long as there is an intersection area that allows the ends of multiple wires to overlap.

[0076] In some preferred embodiments, rubber pads 18 are respectively provided in the first inclined groove 16 and the second inclined groove 17;

[0077] The second clamping block 11 has an inner cavity in which a battery and a wireless transmission module are placed respectively; a miniature pressure sensor is fixed on the surface of the rubber pad 18 of the second inclined groove 17; the miniature pressure sensor is electrically connected to the wireless transmission module.

[0078] The battery provides power to the wireless transmitter module and the miniature pressure sensor, respectively.

[0079] The wireless transmission module transmits the signal to the controller via the wireless transmission module.

[0080] In some preferred embodiments, the first clamping block 12 and the second clamping block 11 are insulating blocks. Further, the insulating block can be a plastic block or a wooden block. To ensure the clamping effect, a metal counterweight is embedded within the insulating block; the counterweight does not contact the inclined groove or the cable.

[0081] In some preferred embodiments, the cable inspection system further includes anti-theft tags, repeaters, and a monitoring host;

[0082] Multiple anti-theft tags are respectively installed on the cable, and the multiple anti-theft tags are arranged at equal intervals;

[0083] One repeater is installed every 180 meters, and the shortest distance between the repeater and the monitoring host is 400 meters.

[0084] The anti-theft tag is wirelessly connected to the monitoring host via the repeater;

[0085] The monitoring host is electrically connected to the wireless transmission module, and the wireless transmission module transmits the signal of the monitoring host to the outside.

[0086] The anti-theft tag contains a smart chip, an MCU processor, and a disposable lithium battery, which can be used for two years under normal conditions. The tag is waterproof and dustproof, monitoring by sensing external vibrations. Once it detects a vibration reaching a set level, it sends a long-range signal to the monitoring host, which then sends a control signal to the alarm to sound. Alternatively, the monitoring host can send a control signal to the wireless transmission module, which transmits the signal to the cloud server. The cloud server then sends a signal to a mobile terminal, allowing administrators to quickly assess the risk of cable theft. The anti-theft tag uses wireless communication technology, emitting only about 1 / 10 the radiation of a mobile phone. The tag's dimensions are 72mm*42mm*8mm, and the battery is 20mm thick. To minimize false alarms during cable installation, the monitoring host can be temporarily shut down during installation to reduce the risk of movement.

[0087] Furthermore, the smart chip of the anti-theft tag is equipped with a vibration sensor, preferably a high-precision vibration sensor. This vibration sensor feeds back the detected vibration signal to the MCU processor. The MCU processor digitizes the measured vibration signal to obtain the measured vibration frequency, and then compares the measured vibration frequency with a set vibration frequency. In some preferred examples, the set vibration frequency is 130Hz. If the measured vibration frequency is greater than 130Hz, the smart chip sends a theft signal to the monitoring host, which in turn sends a theft signal to the controller or cloud server. Since the vibration frequency of cables under normal wind speed is less than 120Hz, vibrations below the set vibration frequency can be considered as vibrations caused by wind. In this case, after comparison by the MCU processor, the result fed back to the smart chip is "normal," and the smart chip does not send a signal to the controller or cloud server.

[0088] Because the wireless signal of the anti-theft tag is transmitted in the form of spherical waves, the transmission distance is approximately 500 meters, which can meet the needs of most point-to-point communications. In areas with weak signals, repeaters can be added to enhance the signal and extend the transmission distance, achieving 100% monitoring coverage and thus eliminating blind spots.

[0089] The monitoring host is waterproof and dustproof, suitable for outdoor installation using clamps (for easy removal), and connects to a 220V power line. It communicates wirelessly with a cloud server. The monitoring host receives an alarm signal when the anti-theft tag or repeater is moved, boasting near 100% accuracy and extremely fast response.

[0090] Furthermore, a monitoring host is installed near one end of the cable, and repeaters are installed at 450-meter intervals between the hosts; an anti-theft tag is installed every 200 meters along the length of the cable. Even more specifically, a repeater is installed every 450 meters along the length of the cable.

[0091] Furthermore, the monitoring host connects wirelessly to the controller via a wireless transmission module, or wirelessly to the cloud server via the same module. This allows for the determination of theft either through the controller or the cloud server.

[0092] Furthermore, the cloud server connects to the card-issuing computer, which in turn connects to the card issuer. The card issuer connects to the card-issuing computer via a USB interface, reads the ID number of the anti-theft tag, and the operator then inputs the specific installation location of the anti-theft tag into the management system, binding it with the tag's ID number. After marking the anti-theft tag's outer shell, the card issuance is complete. The card issuer can reissue anti-theft tags for convenient reuse.

[0093] The control system adopts a B / S architecture. Administrators only need to log in to the system. With a network connection, they can log in through a user terminal (computer or mobile phone) to monitor theft around the clock and without geographical limitations.

[0094] In some preferred embodiments, the warning system includes a housing 30, a power supply unit, a warning control unit, a distance sensor 20, and a wireless communication unit;

[0095] The bottom surface of the outer casing 30 has at least two vertical pins 33;

[0096] The outer casing 30 has a cavity inside; the power supply unit, the warning control unit, and the wireless communication unit are respectively installed in the cavity;

[0097] The distance sensor 20 is installed on the bottom surface of the housing 30 with its detection direction facing downwards; and the distance sensor 20 is electrically connected to the warning control unit.

[0098] The power supply unit provides power to the warning control unit, the distance sensor 20 and the wireless communication unit respectively;

[0099] The loop fitting component 10 is placed inside the cavity of the outer shell 30;

[0100] The wireless communication unit is wirelessly connected to the wireless transmission module and transmits signals through the wireless transmission module.

[0101] Furthermore, the power supply unit is a storage battery or a rechargeable battery.

[0102] In a further embodiment, the outer casing 30 includes an upper cover 31, a lower housing 32, a lock body 34, and the aforementioned pins 33. One side of the upper cover 31 is hinged to the lower housing 32, and the other side of the upper cover 31 is locked or unlocked to the lower housing 32 via the lock body 34. Two pins 33 are installed on the bottom surface of the lower housing 32. The upper cover 31 and the lower housing 32 each form a receiving space, which, when fastened together, forms the cavity. The power supply unit, the warning control unit, and the wireless communication unit are respectively installed on the bottom surface of the receiving space of the lower housing 32; the loop fitting assembly 10 is placed within the receiving space of the lower housing 32. A distance sensor 20 is installed on the bottom surface of the lower housing 32, with its detection direction downwards, to determine the height of the lower housing 32 above the ground.

[0103] Furthermore, the insertion foot 33 is tapered for better insertion into the soil.

[0104] Furthermore, a through-hole 35 is provided on the lower housing 32 for the cable to pass through, so that the cable enters the lower housing 32 through the through-hole 35 and connects with the loop fitting assembly 10 inside the lower housing 32. The through-hole 35 is a flat elongated strip, which firstly prevents hands from reaching into the lower housing 32, and secondly ensures the passage of the cable.

[0105] In some preferred embodiments, the warning system further includes a loudspeaker installed within the cavity of the housing 30 and electrically connected to the warning control unit; the power supply unit provides power to the loudspeaker.

[0106] Furthermore, the loudspeaker serves as an alarm, capable of emitting warning sounds to alert the system when it determines that the device is in a stolen state.

[0107] In some preferred embodiments, the warning system further includes a cloud server and a user terminal;

[0108] The wireless transmission module interacts wirelessly with the cloud server, and the cloud server interacts wirelessly with the user terminal.

[0109] The wireless communication unit wirelessly transmits the signal to the wireless transmission module, and then transmits it to the cloud server through the wireless transmission module.

[0110] In some preferred embodiments, the warning system further includes a first camera and a second camera;

[0112] The first camera is electrically connected to the wireless transmission module;

[0113] The second camera is installed inside the cavity of the housing 30 and placed in a corner of the cavity; the second camera is electrically connected to the wireless communication unit; and the power supply unit provides power to the second camera.

[0114] The first camera is used to monitor the facilities and personnel at one end of the cable; the second camera is used to monitor the facilities at the other end of the cable and record the scene when the cable is stolen.

[0115] In some preferred embodiments, the cable inspection system further includes a secondary receiving unit connected to the other end of the cable;

[0116] The secondary receiving unit is electrically connected to the wireless communication unit, and is powered by the power supply unit.

[0117] The controller controls the pulse signal generating unit 81 to emit pulse signals;

[0118] The secondary receiving unit and the signal receiving unit respectively send the received pulse signals to the controller;

[0119] The controller determines whether it has received signals from the secondary receiving unit and the signal receiving unit.

[0120] The working principle of the monitoring system for cable theft prevention in this application:

[0121] The first step is to determine whether the transmission and reception of pulse signals are normal.

[0122] In one example, a pulse signal generating unit 81 is connected to one wire at one end of cable 90, and contacts 82 of a signal receiving unit are connected to the other wires at the same end. At the other end of cable 90, all wires are connected together via a loop fitting component 10. Thus, each pair of wires forms a loop. The pulse signal generating unit 81 emits a pulse signal, which is received by the signal receiving unit from each wire. Each receiving wire corresponds to an interface of the signal receiving unit. The signal receiving unit transmits the received signal to the controller, which then transmits the signal to the cloud server via a wireless transmission module. The cloud server processes the signal and sends the data to the user terminal. If the pulse signal transmission and reception are normal, the cable is likely intact.

[0123] In another example, a pulse signal generating unit 81 is connected to one wire at one end of cable 90, and a signal receiving unit is connected to the other wire at the same end, with its contact point 82 connected. For distinction, this signal receiving unit is named Receiving Unit A. At the other end of cable 90, all wires in the cable are connected together via a loop fitting component 10. A signal receiving unit is also connected to the other end of the cable, with its connection point 83 connected. This signal receiving unit is named Receiving Unit B. A pulse signal is emitted by the pulse signal generating unit 81, and it is determined whether Receiving Unit A and Receiving Unit B receive the pulse signal. If Receiving Unit B receives the pulse signal and transmits it wirelessly to the controller or cloud server, it indicates that the connection from signal emission to the first reception is unobstructed, suggesting that part of the cable may be intact at this point. If Receiving Unit A also receives the pulse signal and transmits it to the controller, it suggests that another part of the cable may also be intact at this point.

[0124] In the two examples above, it's possible that the cable was cut in the middle and the two ends were connected, requiring further investigation.

[0125] If no pulse signal is received in either of the two examples above, it indicates that the cable is at risk of being stolen. The system will then send a signal to the controller and the cloud server, and issue a warning (to the user terminal) and sound an alarm (via an alarm and loudspeaker).

[0126] The second step is to determine if the middle section of the cable is intact.

[0127] First, the anti-theft tag's feedback indicates whether theft has occurred. If the anti-theft tag's vibration value exceeds the set value, it indicates a risk of theft, as it is possible that the cable was not properly secured and was vibrating due to wind.

[0128] Secondly, the distance sensor 20 connected to the outer casing 30 is used to make a judgment. If the value fed back by the distance sensor 20 changes drastically, it indicates that the outer casing 30 has been lifted off the ground, which in turn indicates the risk that the other end of the cable has been moved or stolen.

[0129] Third, when the aforementioned risks exist, the controller and cloud server send control signals to activate the first and second cameras, respectively, and transmit the captured images to the cloud server. Based on the images captured by the first and second cameras, the user terminal makes an active assessment. If theft is detected, the user terminal issues an alert, which is transmitted via the cloud server to the loudspeakers and alarms at both ends of the cable to warn of the theft.

[0130] Furthermore, the monitoring system for cable theft prevention proposed in this application can promptly detect whether cables have been stolen, from where they were stolen, and in what manner they were stolen, and can make a comprehensive judgment to avoid misjudgment. It offers strong comprehensive anti-theft capabilities, combining multiple methods to fully ensure the safety of cables not yet in use at the construction site, and also reduces construction costs for enterprises.

[0131] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
