[0002] With the continuous development of electricity, the demand for electricity has increased significantly, and the subsequent substantial increase in electricity costs has led to a large number of electricity thefts. With the rapid development of science and technology, the means of electricity theft have also shifted from open to covert. The means of electricity theft have developed from relatively primitive means to the current high-frequency, high-power wireless electricity theft and other high-tech electricity thefts. High-tech electricity thefts are difficult to detect, highly concealed, and difficult to obtain evidence.

[0003] At present, in the existing anti-electricity theft technology, wireless communication technology is usually used for anti-electricity theft monitoring and management, but the anti-electricity theft monitoring process without communication technology has the following defects: 1. Wireless communication still has the technical problem of being easily interfered with, and the stability of wireless communication technology is relatively low; 2. Communication signals have the problem of poor timeliness; 3. On-site evidence collection, such as checking whether there are traces of moving meter boxes, has poor flexibility, and the authenticity of the evidence data is difficult to determine. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-electricity theft device based on carrier communication, which is used to solve the technical problems of easy interference and low stability of wireless communication in the anti-electricity theft process, improves the timeliness of communication signals and makes evidence collection more covert and flexible.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] An anti-electricity theft device based on carrier communication technology includes a meter box, a monitoring device in the box, a repeater and a monitoring terminal, wherein the monitoring device in the box includes a signal collector, a carrier processor and a camera device arranged in the meter box; the carrier processor includes a video data receiving module, a wireless data receiving module, a video data conversion carrier data module, a wireless data conversion carrier data module and a carrier data sending module, wherein the signal collector is communicatively connected to the input end of the wireless data receiving module for transmitting the collected monitoring data to the carrier processor; the output end of the camera device is communicatively connected to the input end of the video data receiving module for transmitting the monitoring data collected by the camera device to the video data receiving module; the video data The output ends of the data receiving module and the wireless data receiving module are respectively communicatively connected to the input ends of the video data conversion carrier data module and the wireless data conversion carrier data module for converting the respectively collected monitoring data into carrier data, the output ends of the video data conversion carrier data module and the wireless data conversion carrier data module are communicatively connected to the input end of the carrier data sending module, and the output end of the carrier data sending module is communicatively connected to the input end of the repeater; the monitoring terminal includes a 4G data receiving module and a CPU processor which are communicatively connected, and the output end of the repeater is wirelessly connected to the input end of the CPU processor for converting the monitoring data collected in the meter box into 4G data through the repeater and sending it to the CPU processor for analysis and processing.

[0007] An anti-electricity theft evidence collection method based on a carrier communication technology anti-electricity theft device comprises:

[0008] Collect induction monitoring data, including primary current data at the meter box inlet, secondary current data at the meter end in the meter box, unpacking induction data, human body induction data, strong magnetic induction data and high-frequency induction data collected by the signal collector; transmit the collected induction monitoring data to the wireless data receiving module through wireless transmission;

[0009] The data information received by the wireless data receiving module is transmitted to the carrier data sending module through the wireless data conversion carrier data module;

When the error between the two side current data is within the set range, it is determined that there is no electricity theft; when it exceeds the set error range, it is determined that there is electricity theft;

[0012] When the CPU processor receives one of the unpacking sensing data, the human body sensing data, the strong magnetic sensing data or the high frequency sensing data, it sends a signal to the camera device and turns on the camera device.

[0021] The present invention is further described in detail below with reference to the accompanying drawings, and specific implementation methods are given.

[0022] like Figure 1-3As shown, an anti-electricity theft device based on carrier communication technology includes a meter box 1, a monitoring device inside the box, a repeater and a monitoring terminal, wherein the monitoring device inside the box includes a signal collector, a carrier processor and a camera device arranged in the meter box 1; the carrier processor includes a video data receiving module, a wireless data receiving module, a video data conversion carrier data module, a wireless data conversion carrier data module and a carrier data sending module, wherein the signal collector is communicatively connected to the input end of the wireless data receiving module for transmitting the collected monitoring data to the carrier processor; the output end of the camera device is communicatively connected to the input end of the video data receiving module for transmitting the monitoring data collected by the camera device to the video data receiving module; the video data receiving module and the wireless data receiving module are connected to each other. The output end is communicatively connected to the input end of the video data conversion carrier data module and the wireless data conversion carrier data module respectively for converting the respectively collected monitoring data into carrier data, the output end of the video data conversion carrier data module and the wireless data conversion carrier data module are communicatively connected to the input end of the carrier data sending module, and the output end of the carrier data sending module is communicatively connected to the input end of the repeater; the monitoring terminal includes a 4G data receiving module and a CPU processor which are communicatively connected, and the output end of the repeater is wirelessly connected to the input end of the CPU processor for converting the monitoring data collected in the meter box 1 into 4G data through the repeater and sending it to the CPU processor for analysis and processing.

[0023] The meter box 1 is provided with a power supply device for powering the camera device in the meter box 1. Specifically, the power supply device includes a dual power supply module, an internal power supply status sensor, an external power supply status sensor, and a wireless data sending module. There are two power supply modes, namely, power supply by the internal battery of the power supply device and power supply by an external power supply. The operating mode is a normal power supply mode using an external power supply. When the external power supply fails, the power supply device automatically switches to internal battery power supply. The power supply mode of the power supply device sends data to the carrier processor through the internal power supply status sensor and the external power supply status sensor through the wireless data sending module. The wireless data conversion carrier data module converts the power supply mode status data into carrier data, and sends the data to the repeater through the carrier data sending module. Then the repeater converts the monitoring data into 4G data through the carrier data conversion 4G data module, and sends the data to the monitoring terminal through the 4G data sending module.

[0024] The signal collector includes but is not limited to an unpacking induction sensor, a human body induction sensor, a strong magnetic induction sensor, a high frequency induction sensor, a current induction sensor and an AC multifunctional data acquisition sensor; each sensor can adopt a specific model of the prior art, for example, the human body induction sensor can adopt the human body sensor model HC-SR505 in the prior art, and its specific structure is not repeated here. The sensor here is set inside the meter box 1 to monitor the data after unpacking. The unpacking induction sensor and the human body induction sensor are used to monitor whether someone has opened the meter box 1. The strong magnetic induction sensor and the high frequency induction sensor are used to monitor whether someone has stolen electricity with strong magnetism and high frequency. The strong magnetic induction sensor adopts a normally open type, that is, the switch is usually disconnected and is turned on when the magnet approaches, and vice versa, it is disconnected when the magnet leaves.

[0025] The above-mentioned camera device includes a camera module and a video data sending module. The camera device transmits the monitoring data to the video data receiving module in the carrier processor through the video data sending module. The video data conversion carrier data module converts the monitoring data into carrier data, and sends the data to the repeater through the carrier data sending module. Then the repeater converts the monitoring data into 4G data through the carrier data conversion 4G data module, and sends the data to the monitoring terminal through the 4G data sending module.

[0026] The CPU processor can use the STM32F407ZGT6 processor. The design principle of the above anti-electricity theft device includes two parts. One part is the induction data collection and processing, such as Figure 2 As shown, the metering device is the meter in the metering box, and the other part is as shown in Figure 3 The camera data acquisition process is shown.

[0027] A primary current collector for collecting the primary current of the incoming line is provided at the incoming line of the meter box 1, a meter is provided in the meter box 1, and the signal collector includes a secondary current collector provided at the meter end and used for collecting the secondary current of the meter end. The primary current collector and the secondary current collector are respectively connected to the wireless data receiving module for communication so that the collected data is transmitted to the monitoring terminal for analyzing and comparing the primary current and the secondary current to confirm whether electricity is stolen.

[0028] An external monitoring device is provided outside the meter box 1, and the external monitoring device includes a photoelectric power generation unit for providing power to the external monitoring device and a carrier camera module for collecting monitoring data outside the meter box 1. The output end of the carrier camera module is connected to the input end of the carrier data sending module for signal transmission with the monitoring terminal.

[0029] like Figure 4-6As shown, one side of the meter box 1 is provided with an opening, and the opening is provided with a door 2 for opening or closing the opening. The internal equipment of the meter box 1 can be inspected or repaired by opening the door 2.

[0030] An alarm device 3 is also provided between the opening and the inner wall of the metering box 1 where the opening is located.

[0031] The alarm device 3 includes an annular conveyor belt 3.2 which is rotatably arranged on the inner wall of the metering box along the edge of the opening, and an alarm light 3.3 is installed on the outer surface of the conveyor belt 3.2. A driving mechanism for driving the conveyor belt 3.2 and the alarm light 3.3 to rotate is also provided on the inner wall of the metering box 1. The driving mechanism and the alarm light 3.3 are wirelessly connected to the monitoring terminal respectively so as to control the opening or closing of the driving mechanism and the alarm light 3.3 through the monitoring terminal. In this embodiment, four gear shafts 3.1 are provided on the inner wall of the metering box 1 where the opening is located, and each gear shaft 3.1 is fixed at the four corner ends of the opening of the inner wall of the metering box, and each gear shaft 3.1 is rotatably connected with a gear (not shown in the figure) through a bearing, and the inner surface of the conveyor belt 3.2 is provided with internal teeth (not shown in the figure). The conveyor belt 3.2 is sleeved on the four gears and meshed with them to form an annular conveying path. The driving mechanism includes a driving motor (not shown in the figure) arranged on the inner side of the annular conveyor belt 3.2, and a driving gear is fixed to the output shaft of the driving motor. The driving gear is meshed with one of the gears in the conveyor belt 3.2 to drive the gear to rotate, thereby driving the conveyor belt 3.2 meshed with the gear to rotate. When the CPU processor analyzes and concludes that electricity theft has occurred, it feeds back a signal to the monitoring terminal and sends a signal to start the drive motor, thereby driving the conveyor belt 3.2 to rotate and the alarm light on the conveyor belt 3.2 starts to emit sound and light. The side of the meter box with an opening can be made of transparent hard material, so when the alarm light emits light, the light can also radiate outward through the side wall of the meter box to serve as an electricity theft warning. The alarm light can select different types of alarm lights in the prior art as needed, and its structure does not belong to the innovation of this embodiment, so the structure of the alarm light is not repeated here. In order to prevent the conveyor belt 3.2 from detaching from the gear, a baffle 3.4 can also be fixed at one end of the gear shaft passing through the conveyor belt 3.2. The baffle 3.4 can be a circular plate and its radial size is designed to limit the conveyor belt 3.2 to a specific size between the baffle 3.4 and the side wall of the meter box 1.

[0032] The external monitoring device also includes a housing 4 for installing a photovoltaic power generation unit and a carrier camera module, and the housing 4 is movably arranged on the outer surface of the meter box 1. The external monitoring device is an integrated device, does not require an external power supply (normal standby time is 1 year), and the communication transmission mode is wireless transmission. The camera data monitored by the carrier camera module is transmitted to the carrier processor by wireless means. The working mode of the carrier camera module is to automatically start the camera when a human body is approaching.

[0033] The outer surface of the metering box 1 is provided with a first telescopic rod 5 and at least three second telescopic rods 6. In this embodiment, only three second telescopic rods 6 are provided. More than three second telescopic rods 6 can be provided according to the need for adjustment. One end of the first telescopic rod 5 is hinged to the outer surface of the metering box 1, and the other end of the first telescopic rod 5 is fixed to the shell 4. Each second telescopic rod 6 is respectively distributed around the first telescopic rod 5 in a ring shape around the first telescopic rod 5. One end of each second telescopic rod 6 is hinged to the outer surface of the metering box 1, and the other end is hinged to one end of the first telescopic rod 5 away from the telescopic end (not shown in the figure). Preferably, the first telescopic rod 5 and the second telescopic rod 6 can be electrically connected to the carrier processor in the metering box and communicated with the CPU processor through the carrier processor. The first telescopic rod 5 and the second telescopic rod 6 are used to adjust the position of the shell 4 relative to the metering box. When the second telescopic rod 6 is controlled to work in coordination, the first telescopic rod 5 can be controlled to tilt in different directions. When the first telescopic rod 5 is controlled to telescope alone, the height of the monitoring device outside the box relative to the metering box can be adjusted to monitor the situation at different positions outside the box. The first telescopic rod 5 and the second telescopic rod 6 may be electric push rods or electric cylinders respectively.
