[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] A terminal block is a type of electrical connector, usually used to easily connect the terminals of cables, wires or devices to devices or instruments. The terminal block detection device provided in the embodiment of the present invention can be applied to an electric energy metering joint terminal box. Among them, the electric energy metering joint terminal box is a special terminal box in the standard wiring of the electric energy metering device. It is widely used in the power industry. It can be used to connect meters or instruments to the secondary circuit in operation, complete various load tests or power inspections, replace electric energy meters and other functions, and can safely replace or inspect electric energy meters, electrical instruments, relay protection and other electrical equipment on-site under load conditions.

[0023] Traditional junction boxes have a low level of intelligence when in use and are unable to analyze and identify electricity thieves. They are also unable to sound an alarm when electricity is stolen, making them less safe to use.

[0024] In view of the above reasons, the embodiments of the present invention aim to design a junction box detection device with a video evidence collection function, which can sound an alarm when electricity is stolen. The development of this device can prevent non-professionals from damaging the junction box equipment. The following is an explanation of multiple embodiments in conjunction with the accompanying drawings.

[0025] Figure 1 A schematic diagram of the structure of a junction box detection device provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the present invention provides a junction box monitoring and early warning device, including a central processing and computing module, a collection module, a video evidence collection module and an alarm module; the central processing and computing module is connected to the collection module, the video evidence collection module and the alarm module respectively;

[0026] One end of the acquisition module is connected to the central processing and calculation module, and the other end of the acquisition module is connected to the electric energy meter through the wiring terminal of the junction box. The acquisition module is used to collect the performance parameters of the junction box circuit and send them to the central processing and calculation module; wherein the performance parameters of the junction box circuit at least include the current, voltage and temperature rise from the electric energy meter to the inlet terminal and outlet terminal of the junction box;

[0027] The central processing calculation module can analyze and process according to the performance parameters of the junction box circuit, and can detect abnormal conditions of the junction box circuit such as overcurrent (current exceeding the rated current), overvoltage (voltage exceeding the rated voltage), undervoltage (lower than the normal rated voltage), temperature rise (exceeding the normal temperature), etc.

[0028] The video evidence collection module is used to capture the image information of the current operator and upload it to the central processing and computing module, so that the central processing and computing module can upload the image information of the current operator to a pre-established image database for matching and identification. If the identification result does not match, the central processing and computing module controls the alarm module to sound an alarm.

[0029] The junction box detection device provided by the present invention can detect the current, voltage and temperature rise from the electric energy meter to the incoming terminal and the outgoing terminal of the junction box in real time through the acquisition module. The image information of the current operator is obtained through the video evidence module and uploaded to the central processing and calculation module. The central processing and calculation module uploads the image information of the current operator to a pre-established image database for matching and identification. If the identification result does not match, the central processing and calculation module controls the alarm module to sound an alarm. The video evidence module can obtain the image information of non-professionals for subsequent evidence collection, prevent non-professionals from damaging the equipment, thereby effectively combating theft of electricity and improving the safety of the junction box.

[0030] It is understandable that traditional electricity meter status detection is usually achieved by arranging personnel for inspection or manually screening the abnormal operation data of the electricity meter through the electricity consumption information collection system, which is not only time-consuming but also inefficient. The present invention can reduce labor costs from the source and improve the inspection and maintenance efficiency of the electricity meter by setting a central processing calculation module and a video evidence collection module.

[0031] In an optional embodiment, the sampling module is composed of an acquisition chip, a signal processing chip, a sampling circuit, a real-time data interface and other devices. One end of the acquisition module is connected to the central processing and calculation module, and the other end of the acquisition module is connected to the electric energy meter through the incoming line terminal of the junction box. When the electric energy meter is working, the voltage, current, and temperature are sampled by the sampling circuit respectively, and sent to the signal processing chip for processing, and then converted into digital signals by the acquisition chip, and sent to the central processing and calculation module for calculation, analysis and processing of the data. The present invention adopts a high-precision acquisition chip, and the acquisition chip completes the front-end high-speed sampling by itself, which can ensure the stability of the electric energy meter measurement algorithm. Reactive energy metering and maximum demand metering functions display various data as needed, communicate and transmit through the RS485 interface, complete the monitoring of operating parameters, and record and store various data.

[0032] Furthermore, the sampling module is connected to the central processing and calculation module, and the current, voltage, temperature rise state, and system operation state of the incoming and outgoing terminals of the junction box are collected in real time through the sampling module. The sampling module is connected to the downstream instrument through the outlet terminal of the junction box to obtain the operation state of the downstream instrument. The process of obtaining the operation state of the downstream instrument includes: the on-site electric energy meter equipment obtains the instrument data, and then collects the instrument data and sends the instrument data to the central processing and calculation module for processing and analysis, so as to analyze and inspect the working condition of the electric energy metering equipment and supervise the customer's electricity consumption.

[0033] In an optional embodiment, the central processing module is a CPU (Central Processing Unit). It is understandable that other information processing devices that can realize information processing functions can be used as central processing modules. The central processing module has high-performance and high-speed computing capabilities, and mainly performs information computing, processing, analysis, transmission and other functions, and is the brain of the Internet of Things module. This embodiment uses CPU as the central processing module. CPU is a large-scale integrated circuit, which is the computing core (Core) and control core (Control Unit) of a computer. Its function is mainly to interpret computer instructions and process data in computer software. The central processing unit mainly includes an operator (arithmetic logic unit, ALU, Arithmetic Logic Unit) and a high-speed cache memory (Cache) and a total (Bus) of data (Data), control and status that realize the connection between them. It is collectively referred to as the three core components of an electronic computer with internal memory (Memory) and input / output (I / O) devices.

[0034] In this embodiment, the central processing module CPU can be logically divided into three parts, namely a control unit, a calculation unit and a storage unit, and these three parts are connected by a CPU internal bus.

[0035] Among them, (1) the control unit is the control and command center of the entire CPU, which consists of the instruction register IR (Instruction Register), instruction decoder ID (Instruction Decoder) and operation controller OC (Operation Controller), etc., and is extremely important for coordinating the entire computer in an orderly manner. It takes out each instruction from the memory in turn according to the program pre-programmed by the user, puts it in the instruction register IR, determines what operation should be performed through instruction decoding (analysis), and then sends micro-operation control signals to the corresponding components through the operation controller OC according to the determined timing. The operation controller OC mainly includes control logic such as the beat pulse generator, control matrix, clock pulse generator, reset circuit and start-stop circuit.

[0036] (2) The arithmetic unit is the core of the arithmetic unit. It can perform arithmetic operations (including basic operations such as addition, subtraction, multiplication and additional operations) and logical operations (including shifting, logical testing or comparing two values). Compared with the control unit, the arithmetic unit accepts the command of the control unit and performs actions, that is, all operations performed by the arithmetic unit are directed by the control signal issued by the control unit, so it is the execution component.

[0037] (3) Storage units include CPU on-chip cache and register groups, which are places where data is temporarily stored in the CPU. They store data waiting to be processed or data that has been processed. The time taken by the CPU to access registers is shorter than the time taken to access memory. The use of registers can reduce the number of times the CPU accesses memory, thereby increasing the CPU's operating speed. However, due to the limitations of chip area and integration, the capacity of the register group cannot be very large. The register group can be divided into dedicated registers and general registers. The function of dedicated registers is fixed, and they store corresponding data respectively. General registers are widely used and their uses can be specified by programmers. The number of general registers varies from microprocessor to microprocessor.

[0038] Furthermore, the CPU includes an arithmetic logic unit, a register unit, and a control unit. The logic unit is in English Logicomponenta; the arithmetic logic unit. It can perform fixed-point or floating-point arithmetic operations, shift operations, and logical operations, and can also perform address operations and conversions. From the perspective of the functions implemented, the CPU can be roughly divided into the following eight logic units:

[0039] 1) Instruction register: It is the instruction warehouse on the chip. With it, the CPU does not have to stop to look for instructions in the computer memory, thereby greatly improving the CPU's computing speed.

[0040] 2) Instruction decoder: It is responsible for interpreting complex machine language instructions into a simple format that can be understood by the arithmetic logic unit (ALU) and registers, just like a diplomat.

[0041] 3) Control unit: Since instructions can be stored in the CPU and there are corresponding instructions to complete the preparations before the operation, there is naturally a role behind it that plays a driving role - it is the operation controller responsible for the entire processing process. According to the instructions from the decoding unit, it will generate control signals to tell the arithmetic logic unit (ALU) and registers how to operate, what to operate on, and how to process the results.

[0042] 4) Register: It is very important for the CPU. In addition to storing part of the program instructions, it is also responsible for storing pointer jump information and loop operation commands. It is a small storage area for data used by the arithmetic logic unit (ALU) to complete the tasks requested by the control unit. Its data source can be any of the cache, memory, and control unit.

[0043] 5) Arithmetic Logic Unit (ALU): It is the intelligent part of the CPU chip and can perform various commands such as addition, subtraction, multiplication, and division. In addition, it also knows how to read logical commands such as OR, AND, and NOT. The message from the control unit will tell the arithmetic logic unit what to do, and then the arithmetic unit will extract data from the register intermittently or continuously to complete the final task.

[0044] 6) Prefetch unit: The performance of the PU is very dependent on it. The prefetch hit rate is directly related to the CPU core utilization, which in turn leads to differences in instruction execution speed. Depending on the requirements of the command or task to be executed, the prefetch unit may obtain data and instructions from the instruction cache or computer memory at any time. When the instruction arrives, the most important task of the prefetch unit is to ensure that all instructions are arranged correctly and then sent to the decoding unit.

[0045] 7) Bus unit: It is like a highway that quickly completes the data exchange between various units. It is also the place where data flows into and out of the CPU from the memory.

[0046] 8) Data cache: stores specially marked data from the decoding unit for use by the logic operation unit, and also prepares the final results distributed to different parts of the computer.

[0047] In this embodiment, the central processing and calculation module obtains the current, voltage and temperature rise parameters from the electric energy meter to the incoming terminal and the outgoing terminal of the junction box through the acquisition module for processing and analysis to obtain the working status of the junction box circuit.

[0048] In an optional embodiment, the alarm module can use an audible and visual alarm, which receives the alarm information sent by the central processing and computing module and sends out alarm signals through sound and various lights. The central processing and computing module can also send the alarm information to a mobile terminal (mobile phone, PAD) or a power management platform through the network to issue an alarm.

[0049] Figure 2 Another structural diagram of the junction box monitoring and early warning device provided by the embodiment of the present invention, referring to Figure 2In an optional embodiment, the junction box monitoring and early warning device further includes a display module, which is connected to the central processing and computing module and is used to display the information processed by the central processing and computing module in a classified manner. In this embodiment, the display module is an LED display screen. It is understandable that other electronic devices that can realize the information display function can be used as display modules.

[0050] Specifically, the display module can display the information processed by the central processing module in a classified manner, and can display the current, voltage, temperature, power, alarm information, operation information, etc. in real time. When the electric energy meter is connected to multiple instruments through the junction box, the operator can directly read the current, voltage, and temperature rise readings of each corresponding instrument on the panel through the LED display screen; and the operating status and fault alarm information of each corresponding instrument are displayed through the LED display screen, indicating which specific instrument is faulty, thereby shortening the fault inspection time and improving the work efficiency of equipment maintenance personnel.

[0051] In this embodiment, the LED display screen is composed of the following six parts: 1. External frame; This is a basic structural frame used to fix the internal frame, and is equipped with hardware parts such as unit boards, circuit boards, switches, and power supplies. 2. Display unit; That is, the main part of the LED screen. It is generally composed of a drive circuit and an LED lamp. In terms of form, if it is an indoor LED screen, it is a unit display board; while an outdoor LED screen is generally in the form of a module box. 3. Scanning control board; The main function is to buffer data. During operation, it can generate various scanning signals and duty cycle grayscale control signals for signal and data transmission between modules. 4. Main controller; During operation, it can generate various control signals, buffer or reorganize digital video signals, etc., so that the LED screen can work normally. 5. Transmission cable; The data generated by the main controller and various other signals can be transmitted to a screen. 6. Display card and multimedia card; In addition to the basic functions of the graphics card, the display card of the LED screen can also output digital signals, blanking signals, etc. at the same time, and transmit these signals to the main controller. In addition, multimedia cards can also convert some input signals into digital signals for video capture.

[0052] In an alternative embodiment, referring to Figure 2 The junction box monitoring and early warning device also includes a communication module, which is connected to the central processing and computing module and is used to transmit the information processed by the central processing and computing module to the power management platform, wherein the power management platform is an Internet of Things information platform established by the power management company.

[0053] It can be understood that the central processing and computing module can connect the power management platform and terminal devices (mobile phones, PADs, computers, etc.) through the communication module, and transmit the current, voltage, temperature, power information and alarm information of the junction box line to the power management platform or terminal devices in real time, thereby realizing the Internet of Things information transmission function.

[0054] In the present embodiment, the communication module is an RS485 wireless communication module. The RS485 wireless communication module is a device for realizing the wirelessization of RS485 wired communication. Generally, RS485 is a common serial communication protocol used for short-distance communication between devices. However, in some cases, it is sometimes necessary to convert RS485 wired communication into wireless communication in order to achieve longer-distance communication. At this time, the RS485 wireless communication module can be used. The RS485 wireless communication module usually consists of two parts: a transmitting end and a receiving end. The transmitting end converts RS485 wired communication into wireless signals and transmits them through an antenna. The receiving end receives these signals through an antenna and converts them into RS485 wired communication. Since the propagation distance of wireless signals is longer than that of wired signals, the RS485 wireless communication module allows longer-distance communication and improves the flexibility and reliability of communication. The use of RS485 wireless communication modules is very extensive, for example, in the fields of industrial automation, building automation, smart home, etc. For example, in the industrial field, field controllers, temperature controllers, PLCs and other equipment often need to communicate. However, the equipment in some industrial venues is far away from each other, and it is inconvenient to use wired connections. The RS485 wireless communication module can solve this problem well.

[0055] In an alternative embodiment, referring to Figure 2 The junction box monitoring and early warning device also includes a storage module, which is connected to the central processing and computing module. The storage module is used to store the performance parameters of the junction box circuit, including the current, voltage and temperature rise from the electric energy meter to the junction box inlet and the junction box outlet. The storage module is also used to store the information processed by the central processing module, including the fault information of the junction box circuit, the alarm information, the image information captured by the video evidence collection module and other data.

[0056] The storage module of the junction box can be a chip, card or memory built into the junction box, or it can be an external device such as a USB flash drive. These storage modules usually have the characteristics of high-speed reading and writing, large capacity, high reliability, and anti-interference, and are suitable for centralized storage, backup, transmission and sharing of data. In the industrial field, the storage module of the junction box is often used for data acquisition, control and monitoring. The storage module of the junction box can store complex control instructions internally so that the operator can read and use them at any time. In addition, during the data acquisition and transmission process of the smart grid, the storage module of the junction box can store the required data in an internal or external storage device for subsequent data analysis and processing. In short, the storage module of the junction box can help users store and transmit data or information, improve the efficiency and accuracy of data processing, and provide strong support for the monitoring and control of equipment in the industrial field.

[0057] In this embodiment, the storage module is a random access memory RAM. It is understandable that other electronic devices that can realize data storage function can be used as storage modules.

[0058] In an optional embodiment, the camera module is mainly composed of three parts, namely a lens, an image sensor, and an image processor. The lens and the image sensor are collectively referred to as a lens module. The camera evidence module can obtain image information of operators or non-professionals (who may be electricity thieves) for subsequent evidence collection. In order to realize the damage evidence of the junction box, it is also necessary to record the time point of opening the junction box and the time point of closing the junction box in real time, and count the number of times the junction box is opened and closed. The image information collected by the camera evidence module is sent to the central processing module and is also sent to the storage module for storage. The central processing module transmits the image information to the power management platform or terminal device through the communication module, and notifies the operator responsible for the area through the power management platform to perform maintenance as soon as possible.

[0059] In an alternative embodiment, referring to Figure 2The junction box monitoring and early warning device also includes a security module, which is connected to the central processing and computing module and is used to encrypt and transmit the information processed by the central processing and computing module. The security module of the junction box refers to adding some specific encryption circuits or encryption equipment to the junction box to improve the security of data transmission and storage of the junction box. In the security module, the commonly used technologies include: Symmetric encryption: using the same key to encrypt and decrypt information to ensure the security and integrity of the information. Asymmetric encryption: using a pair of keys to encrypt and decrypt information before information transmission, one of the keys is open to the public, and the other key can only be obtained by the information recipient, thereby ensuring the legitimacy of the recipient and the security of the information. Digital signature: Create a digital signature by using a private key to prove the authenticity and integrity of the information and prevent the information from being tampered with and forged during transmission. Identity authentication: Verify the identities of the communicating parties through an algorithm to ensure the security of communication.

[0060] In this embodiment, the security module of the junction box can effectively prevent data leakage, privacy infringement or other illegal operations. The security module can be applied to various fields of the junction box. For example, in industrial automation, the security module of the junction box can effectively maintain data transmission security and prevent device data from being stolen or adversely affected. In this embodiment, the security module of the junction box can ensure the security of data transmission and storage, and improve the security and reliability of the system.

This junction box 3 adopts contact and snap-on connection, and no screw connection is required throughout the process. The overall wiring adopts interference fit, etc., which saves installation time.

[0062] In summary, the embodiment of the present invention provides a junction box monitoring and early warning device, which can detect the current, voltage and temperature rise from the electric energy meter to the incoming terminal and the outgoing terminal of the junction box in real time through the acquisition module. The image information of the current operator is obtained through the video evidence module and uploaded to the central processing and computing module. The central processing and computing module uploads the image information of the current operator to a pre-established image database for matching and identification.
