Description

Technical Field

[0001] This utility model relates to the field of cable anti-theft technology in railway signal laying construction, and in particular to an intelligent cable anti-theft monitoring device based on EC800M. Background Technology

[0002] In the construction of railway signaling systems, the current cable laying work adopts a construction mode of pre-laying cables and segmented wiring. A single line often stretches for tens or even hundreds of kilometers. Workers usually use vehicles to lay all the cables in the correct positions in advance, and then carry out the cable wiring work. The entire line is quite long, which means that traditional cable theft prevention relies on manual inspection or video surveillance, resulting in a variety of problems and technical bottlenecks.

[0003] Currently, the most common method is manual inspection. This mechanism has inherent flaws. Physically, cables are laid underground alongside railway tracks, requiring inspectors to often use track inspection vehicles to check each section, and on foot until the track is fully laid, resulting in a daily inspection mileage of less than 20 kilometers. In terms of efficiency, manual inspection is delayed; a cable theft incident typically takes about 5 hours from occurrence to discovery, by which time the cable is already lost, making recovery extremely unlikely. If video surveillance is used, the overall construction route is long, resulting in very low overall power coverage. In special sections, power wiring is cumbersome, and installation costs are too high.

[0004] Secondly, electronic monitoring systems are commonly used, but this method suffers from drawbacks such as high false alarm rates, ambiguous location, and limited functionality. This monitoring technology is also highly susceptible to temperature, humidity, and electromagnetic interference. When the daily average temperature fluctuation exceeds 15 degrees Celsius, or when there is significant electromagnetic interference in the environment, the false alarm rate may exceed 40%. Furthermore, this monitoring mode cannot accurately pinpoint the location of lost cables or track stolen cables, and it relies on existing, fully-connected power lines, limiting its applicability to certain environments.

[0005] Meanwhile, existing methods lack intelligent and digital operation and maintenance management. Manual anti-theft inspection logs rely on paper archives and have not yet achieved data interoperability with current BIM visualization models and GIS geographic information systems, making it impossible to obtain cable status in real time. When a theft incident occurs, data from multiple systems needs to be manually retrieved for fault analysis, resulting in a long average response time.

[0006] In summary, existing anti-theft methods have certain limitations, resulting in huge economic losses due to cable theft every year. At the same time, this problem may seriously threaten the safety of railway transportation. Therefore, there is an urgent need for a digital, highly reliable intelligent anti-theft solution.

[0018] Preferably, the interrupt control module is equipped with a button and a buzzer. The button triggers the device state switch, and the associated buzzer provides alarm feedback.

[0019] Preferably, the intelligent cable anti-theft monitoring device further includes a bottom shell, a top cover, and a sleeve. Each functional unit is sealed and installed in the groove of the bottom shell, and can be detachably installed at any position of the cable using the sleeve.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In some embodiments, such as Figure 1 As shown, to address the issues of response delay and ambiguous positioning in existing cable anti-theft methods, an intelligent cable anti-theft monitoring device based on the EC800M is provided. This intelligent cable anti-theft monitoring device 100 can be one or more units, all of which are installed at any position on the cable (power transmission line) using cable clamps. The device mainly includes a power management module 101, a main control module 102, an attitude and displacement monitoring module 103, and a communication module 104.

[0031] The power management module 101 is connected to the main control module 102 and the attitude and displacement monitoring module 103 via a voltage divider circuit, and is used to supply power to the main control module 102 and the attitude and displacement monitoring module 103. The main control module 102 adopts a multi-functional integrated EC800M chip, which is wirelessly connected to the remote monitoring platform 200 through the communication module 104. The EC800M chip simultaneously undertakes three major functions: main control, communication, and positioning, and works with the attitude and displacement monitoring module 103 to identify theft activities.

[0032] This GPS cable intelligent cable anti-theft monitoring device collects triaxial acceleration data in real time through the attitude and displacement monitoring module 103; when the cable tilt angle change Δθ>15°, it activates the positioning module to obtain coordinates; the BD-09 coordinates are uploaded to the remote monitoring platform 200 via the communication module; at the same time, it triggers a buzzer alarm and activates an external sound and light alarm.

[0033] In some embodiments, the power management module 101 consists of a Type-C interface and an ETA6002 chip, connected to the ADC interface of the main control module 102 via a voltage divider circuit. The 5V of the Type-C interface serves as the charging input, and the 3.7V~4.2V of the lithium battery serves as the operating input. The power management module 101 is connected to the lithium battery 106, which supplies power to the power management module 101. The lithium battery 106 is a 4000mAh battery.

[0034] Specifically, when the VIN pin of the ETA6002 on the power management module 101 detects an input voltage >4.5V (typical value), the internal power manager is activated; the BAT pin is connected to the ADC interface of the EC800M through a voltage divider circuit to realize battery power detection; the STAT pin is connected to an LED to realize charging reminder. The output of the ETA6002 provides power to the device, outputting the battery voltage in the charging state, and stably outputting 4.2V when fully charged; it outputs the battery voltage in the discharging state.

[0035] In some embodiments, the main control module 102 integrates a GNSS positioning unit, which is connected to the attitude and displacement monitoring module 103 via an I²C bus. The main control module 102 is model EC800MCNGB-I05-SGNSA.

[0036] The EC800M chip employs a quad-core processor architecture with a clock speed of 1.3GHz~1.5GHz, supporting efficient multitasking. It includes a rich software protocol stack such as TCP / UDP / PING / FILE / MQTT / NTP / HTTP / HTTPS / SSL, etc.; provides up to 30~40 programmable GPIOs, supporting level control, interrupt triggering, and other functions; has dedicated interfaces for USART, USB, IIC, and ADC; and features built-in GNSS for accurate positioning, eliminating the need for an external GNSS module to obtain GPS data. Its ultra-small size saves PCB layout space, making it ideal for designing this system solution.

[0037] In some embodiments, the attitude and displacement monitoring module 103 uses an MPU6050 chip, which is connected to the main control module 102 via a PCA9306 level conversion chip. Preferably, the attitude and displacement monitoring module 103 uses a three-axis gyroscope sensor with a tilt angle change detection threshold of 30° and a response time of <0.5 seconds.

[0038] This intelligent cable anti-theft monitoring device uses the IIC interface of the EC800M chip, the MPU6050 chip, and the PCA9306 to acquire three-axis information. The PCA9306 is used for level conversion in IIC communication; both the IIC interfaces of the EC800M chip and the MPU6050 chip require pull-up resistors.

[0039] In some embodiments, the communication module 104 employs a 4G antenna (OA-L01) for transmitting alarm data to the remote monitoring unit (200). A small-sized 4G antenna OA-L01 and a small-sized GNSS antenna CA-G01 built into the EC800M chip are selected. The 4G antenna OA-L01 is connected to the main antenna interface ANT_MAIN of the EC800M chip, and the GPS antenna CA-G01 is connected to the GNSS antenna interface ANT_GNSS of the EC800M. Impedance matching uses L / C matching to achieve a 50Ω impedance transformation; there is no copper foil around the antenna, and the remaining layers are perforated to reduce parasitic capacitance.

[0040] In addition, such as Figure 1 and Figure 2 As shown, the EC800M-based intelligent cable anti-theft monitoring device also includes an interrupt control module 105, which is connected to the main control module 102 and is used to trigger device state switching. Specifically, the interrupt control module 105 is equipped with a button 1051 and a buzzer 1052. The device state switching is triggered by the button 1051, and the alarm feedback is provided by the associated buzzer 1052.

[0041] The interrupt handling mechanism of the device is constituted by the interrupt control module 105. Specifically, an external interrupt is used to control the device's working state to be ready. When the device is not ready, this interrupt button is triggered and the buzzer sounds once to change the state to ready. When the device is ready, this interrupt button is triggered and the buzzer sounds twice to change the product to not ready.

[0042] In some of these embodiments, such as Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the intelligent cable anti-theft monitoring device 100 also includes a bottom shell 107, a top cover 108, and a clip 109. Each functional unit is sealed and installed in the groove of the bottom shell 107, and can be detachably installed at any position on the cable using the clip 109. Each functional unit, such as the power management module 101, the main control module 102, the attitude and displacement monitoring module 103, the communication module 104, and the lithium battery 106, is installed in the groove of the bottom shell 107. The top is sealed and pressed together using the top cover 108. After the clip 109 is placed on the cable, bolts are used to lock and fix the bottom shell 107, the top cover 108, and the clip 109 at both ends. The fixing clip composed of the bottom shell 107, the top cover 108, and the clip 109 allows the intelligent cable anti-theft monitoring device 100 to be installed at any position on the cable, making installation and disassembly simple and convenient.

[0043] like Figure 3 and Figure 4As shown, at least one first arc-shaped groove 1081 is provided on the top of the upper cover 108, and at least one second arc-shaped groove 1091 is provided on the bottom of the sleeve 109. The first arc-shaped groove 1081 and the second arc-shaped groove 1091 constitute a through mounting hole for mounting and fixing the cable. Preferably, the sleeve 109 is an isosceles triangle structure, with the second arc-shaped groove 1091 at the bottom and ear plates 1092 at both ends. The ear plates 1092 have through holes 1093 for mounting bolts, and reinforcing ribs 111 are provided on the top and two sides of the sleeve 109.

[0044] like Figure 5 and Figure 6 As shown, a battery fixing groove 1071 for installing a lithium battery 106 is provided in the groove bottom of the bottom shell 107. One end of the lithium battery 106 is fixedly installed on the inner wall of the bottom shell 107 by a spring 1072, which serves to fix the lithium battery 106. The bottom shell 107 has threaded holes 1073 corresponding to through holes 1093 at both ends, and an upwardly protruding flange 1074 is provided on the top periphery to mate with the bottom periphery of the top cover 108, ensuring a tight seal between the bottom shell 107 and the top cover 108 and preventing rainwater from seeping into the bottom shell 107. Of course, a rubber sealing ring can be provided between the bottom shell 107 and the top cover 108 as needed.

[0045] The method of using the EC800M-based intelligent cable anti-theft monitoring device is as follows: fix the device to the cable joint using a magnetic bracket; press and hold the button on the interrupt control module 105 for 3 seconds to enter the ready state (single buzzer sound); when the cable tilts by more than 30° due to theft, the MPU6050 on the attitude and displacement monitoring module 103 outputs an acceleration change signal to the EC800M chip on the main control module 102; the EC800M chip obtains the GNSS coordinates (e.g., 116.404°E, 39.915°N), converts them to BD-09 (e.g., 116.416°E, 39.921°N); then sends the BD-09 coordinate information to the remote monitoring platform 200 via the 4G module; at the same time, the buzzer alarm on the interrupt control module 105 is triggered and the external sound and light alarm is activated.

[0046] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
