Technical Field

[0001] The invention belongs to the technical field of electric energy meter information debugging, and in particular relates to a handheld infrared and wireless integrated electric energy meter information debugging device. Background Art

[0002] As the intelligentization of power systems continues to advance, the role of energy meters in power monitoring and management has become increasingly prominent. Modern energy meters can not only accurately measure power consumption, but also integrate multiple functions, such as load monitoring, power consumption analysis, and fault diagnosis. These functions have put forward higher requirements on the work of power maintenance personnel, who need to quickly obtain and analyze the data of energy meters in order to deal with various power faults in a timely manner.

[0003] However, the current way of reading electric energy meters often relies on wired communication (such as RS485), which brings many inconveniences in on-site maintenance. When remote wired communication is not available, operators must go to the site to connect the wires to read the information of the electric energy meter, which increases the complexity of the work and labor costs. In addition, this manual operation is not only time-consuming, but also prone to wiring errors, affecting the efficiency of troubleshooting.

[0004] To solve this pain point, a portable handheld infrared wireless integrated energy meter information debugging device was developed. The device uses infrared wireless communication technology to quickly read relevant information of the energy meter, such as model, manufacturer, and current, without physical connection. This innovative design greatly simplifies the operation process, allowing on-site maintenance personnel to complete the data reading and analysis of the energy meter conveniently and efficiently, thereby improving the efficiency and safety of power system management. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art by reading the data of the electric energy meter and performing opening and closing operations through wireless communication, and to provide a handheld infrared wireless integrated electric energy meter information debugging device. The present invention utilizes infrared wireless communication technology to quickly read the relevant information of the electric energy meter without a physical connection.

[0006] The technical solution adopted by the present invention to solve the problems existing in the prior art is that the handheld infrared wireless integrated electric energy meter information debugging device comprises a control module, an infrared module, a display module, a power supply module and a key module.

[0007] The control module is connected with the infrared module, the display module and the key module.

[0008] The infrared module communicates with the electric energy meter to read data and transmit opening and closing instructions.

[0009] The display module is connected to the control module and displays data information and switch opening and closing information.

[0010] The key module inputs key instruction information to the control module.

[0011] The device housing is made of high-strength ABS plastic that is impact-resistant and corrosion-resistant, and the surface is treated with an anti-slip finish.

[0012] The main control chip of the control module is specifically STM32F103ZET6.

[0013] The display module is specifically an LCD high-definition display screen.

[0014] The infrared module is specifically an infrared transmitting tube whose transmitting angle is set to ±30 degrees, and adopts 38kHZ infrared transmitting and receiving technology.

[0015] The infrared module uses the DL / T645 communication protocol to read the electric energy meter information and decrypt the communication message to obtain the specific content.

[0016] The power supply module is used to supply power to the control module and the display module.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The device is highly portable, and its appearance design is close to common handheld devices. It is light and easy to carry, and is particularly suitable for on-site operators to perform quick operations in different locations. The device can read the information of the electric energy meter through infrared communication, which solves the cumbersome process of manual on-site wiring when the traditional wired RS485 communication is interrupted. The operator only needs to align the device with the electric energy meter, without complicated wiring operations, to complete the reading of the electric energy meter information and the execution of related instructions, which greatly improves work efficiency.

[0019] 2. The device is equipped with a high-definition LCD display screen, which can intuitively present various data of the energy meter, including the model, manufacturer information, current, etc. The operator can easily complete the operation through physical buttons, and the interface is simple and clear, reducing the possibility of misoperation. In addition, the device can perform in-depth data analysis on the energy meter, check the battery life, detect the damage of the acquisition module, and determine whether there is electricity theft, which greatly improves the intelligent level of data management.

[0020] 3. The device has high protection and adopts IP65 waterproof design, which enables it to work normally in humid and dusty environments. This not only improves the durability of the equipment, but also reduces maintenance costs, ensuring that the device can maintain stable operation for a long time in complex working environments. The device uses an efficient infrared communication module and a low-power main control chip to ensure the continuous working time of the equipment and meet the needs of long-term field use.

[0021] In summary, the present invention significantly improves the efficiency of on-site commissioning and maintenance of electric energy meters through its portability, ease of operation, data analysis capabilities, and high protection performance, and provides operators with a more intelligent and reliable solution.

For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0026] In the description of the present invention, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention.

[0027] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The handheld infrared wireless integrated electric energy meter information debugging device of the present invention is further described in detail below with reference to the accompanying drawings, but it is not intended to limit the present invention.

[0029] like Figures 1-2 An embodiment of the present invention is described in detail below.

[0030] The device comprises a control module, an infrared module, a display module, a power supply module and a key module.

[0031] The main control chip of the control module adopts STM32F103ZET6, which is specifically a high-performance microcontroller based on the ARMCortex-M3 core, with a main frequency of 72MHz, built-in 128KB Flash storage and 20KB SRAM. The chip supports multiple communication interfaces, such as USART, I2C, SPI, etc., and can adapt to different data transmission requirements. In addition, the chip has good low-power management function, so that the device can still maintain a stable and efficient working state during long-term operation.

[0032] The infrared module on the top of the device uses 38kHz infrared transmission and reception technology, and the transmission angle of the transmitting tube is ±30 degrees, ensuring that the infrared signal has a wide coverage range and stable transmission. The response time of the receiving module is less than 10 microseconds, which can quickly decode the signal and complete the command operation. The infrared module has anti-interference ability, and can still ensure the accuracy and reliability of data transmission even in a complex electromagnetic environment, greatly improving the efficiency of on-site operations.

[0033] The display module is specifically an LCD high-definition display screen with a resolution of 480×320 pixels and excellent display effect. The screen material is scratch-resistant glass, which has been specially treated to have good anti-reflection ability, ensuring that various information read from the electric energy meter can be clearly presented under different lighting conditions.

[0034] There are three physical buttons below the screen, which can be used by operators to read data, open and close the gate. The device shell is made of high-strength ABS plastic, and the surface is anti-slip treated. It has excellent impact resistance and corrosion resistance, and can cope with various environments in field operations. The device is ergonomically designed, comfortable to hold, weighs about 600 grams, is light and portable, and is suitable for long-term operation by field personnel without causing fatigue.

[0035] The device adopts IP65 waterproof design. The shell is sealed, and all buttons and interfaces use durable silicone seals to effectively prevent the intrusion of moisture and dust. In a humid or dusty environment, the device can maintain a stable operating state, ensuring the reliability and durability of the device under harsh working conditions.

[0036] The specific operation method of the device is that the device can be operated after it is turned on. After pressing the read button, the infrared probe of the infrared module communicates with the electric energy meter. After receiving the data, the control module uses the DL / T645 protocol to decode and process, and displays the data on the display module.

[0037] After pressing the opening button, the control module sends a command to the electric energy meter through the infrared probe of the infrared module. The electric energy meter performs the opening operation and sends the result to the infrared module of the device via infrared. After receiving it, the infrared module transmits it to the control module for decoding and reading using the DL / T645 protocol. When it is determined that the electric energy meter fails to open the gate, the opening command is sent again through the infrared module until the gate is opened successfully.

[0038] After pressing the closing button, the control module sends a command to the electric energy meter through the infrared probe of the infrared module. The electric energy meter performs the closing operation and sends the result to the infrared module of the device via infrared. After receiving it, the infrared module transmits it to the control module and uses the DL / T645 protocol for decoding and reading. When it is determined that the electric energy meter fails to close, the closing command is sent again through the infrared module until the closing is successful.

[0039] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
