[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] This utility model provides a smart energy meter with high protection performance, combined with Figures 1 to 4 In this embodiment, the smart energy meter with high protection performance includes:

[0030] The first housing 10, the second housing 20, and the control circuit board 30 are fixedly connected to protect the internal structure. The control circuit board 30 is disposed on the second housing 20 and placed in the cavity formed by the first housing 10 and the second housing 20. The upper surface of the first housing 10 is provided with a module compartment 40 and a low-power battery 50. The side of the first housing 10 is provided with an end cap 60. An insulating sheet 70 is also provided on the side of the second housing 20 near the low-power battery 50.

[0031] In this embodiment, the first housing 10 and the second housing 20 are connected by bolts 80; in other embodiments, the first housing 10 and the second housing 20 may also be connected by means of snap-fit ​​or other means.

[0032] Furthermore, in this embodiment, it also includes a main control unit, a metering unit, a display unit, a storage unit, a power supply unit, and a communication unit, all of which are disposed within the cavity formed by the first housing and the second housing.

[0033] Specifically, the main control unit is model HT6025K, and its circuit diagram is as follows: Figure 2 As shown, this is a multi-functional, high-performance, low-power smart energy meter dedicated 256K MCU chip. Internally, it integrates a Cortex-M0 processor, clock management, power management, hardware automatic temperature compensation RTC, PLL, high-frequency RC, low-frequency RC, LCD driver, and other units, as well as NVIC and DEBUG debugging functions. The display unit is controlled by the main control unit. The power supply unit provides power to each unit to ensure its normal operation. The main control unit also controls communication with the metering unit and storage unit to read and store the user's energy consumption information, which is then displayed externally through the display unit. The communication unit includes Bluetooth communication, which can read the energy consumption, date, account number, and other information from the energy meter. Bluetooth is a wireless technology that enables wireless communication between devices (generally within 10 meters). It facilitates wireless information exchange between numerous devices, including mobile phones, PDAs, wireless headsets, laptops, and related peripherals. Bluetooth technology effectively simplifies communication between mobile communication terminals and between devices and the Internet, making data transmission faster and more efficient, thus paving the way for wireless communication. Bluetooth communication has low power consumption, making it suitable for short-range wireless communication. Furthermore, pairing and connecting Bluetooth devices is relatively simple, providing a good user experience. The schematic diagram of the Bluetooth module used in this embodiment is shown below. Figure 3 As shown, pins 5 and 6 of the module are standard interfaces for UART communication, used for data interaction between the main control unit and the Bluetooth module. The Bluetooth module has a dedicated Bluetooth chip that supports the standard Bluetooth protocol. Information such as the electricity meter's power consumption is transmitted to the outside world via Bluetooth communication.

[0034] Furthermore, in this embodiment, the power supply for Bluetooth communication is provided by the power supply unit. However, in order to ensure stable operation of the peripherals upon power-up, the power-up sequence between the peripherals needs to be controlled by the main control unit. Specifically, the Bluetooth power control method of the smart energy meter is as follows: Figure 4As shown, the main control MCU controls the Bluetooth power supply by controlling the base of the PNP transistor Q810. When the base of Q810 is low, the transistor is turned on, and the linear regulator (LDO) U805 supplies power to the Bluetooth module through the emitter and collector of the transistor. When the base of Q810 is high, the transistor is turned off, the Bluetooth module is powered off, and Bluetooth stops working. This embodiment controls the Bluetooth power supply by using this PNP transistor and LDO, thereby controlling the power-on and power-off sequence of the Bluetooth power supply, and thus achieving stable power-on operation between various peripherals.

[0035] The working process of the smart energy meter with high protection performance provided in this embodiment is as follows:

[0036] The metering unit collects information such as voltage and current from the user's power grid, calculates the electricity consumption, and transmits the data to the main control unit. The main control unit then transmits this data to the storage unit for storage. The storage unit stores data such as the electricity meter's communication parameters and operating status records. The main control unit can control the reading and writing of the memory to write data into or retrieve data from the memory. When external parties need to view the electricity meter data, the user's basic information and electricity consumption status can be displayed through the communication unit and display unit.

[0037] The smart energy meter with high protection performance described in the above embodiments, compared with the prior art, ordinary energy meters only have an IP54 protection rating, which is insufficient to cope with such harsh environments. This leads to power companies replacing the meters, seriously affecting residents' normal lives. Furthermore, when the energy meter is installed in a hard-to-see location, residents cannot easily check their electricity consumption, thus the existing conditions are also detrimental to residents' electricity experience. In contrast, the present invention has a simple structure and convenient operation. Its high-protection shell achieves an IP68 dust and water protection rating, enabling the energy meter to operate in particularly harsh environments, expanding the range of applications. It also supports Bluetooth wireless meter reading, facilitating residents to check their electricity consumption, improving the convenience and flexibility of reading energy meter data, and greatly enhancing the customer's electricity experience.
