Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart meter technology, and specifically to a smart meter. Background Technology
[0002] Smart meters are a general term for electricity meters that have automatic metering and billing functions as well as data transmission capabilities. The core equipment for power distribution management is the smart meter. A smart meter is a digital meter that contains a microcomputer (microprocessor), input and output interfaces, communication devices, and a display screen.
[0003] With the increasing intelligence and networking of electricity meters, most users can check their electricity bills on their mobile phones. However, real-time electricity consumption still requires observation of the meter readings. In addition, most rental properties use individual meters, and the bills are still paid by the homeowner, while the tenant needs to manually read the meter and pay. Most existing meters are installed at high places, requiring ladders or stools to read them, which is inconvenient for users to check quickly. Utility Model Content
[0004] Based on the above problems, the purpose of this utility model is to provide a smart meter.
[0005] To address the above problems, the following technical solution is provided: A smart meter, comprising a meter body and a casing. The meter body includes a power supply module, a measurement module, a main control module, a data storage module, an LED display module, a voice broadcast module, a communication module, and a sensing module. The measurement module, data storage module, LED display module, voice broadcast module, and sensing module are respectively connected to the I / O interface of the main control module. The communication module is electrically connected to the main control module. The power supply module provides the required voltage to each module. The LED display module contains a high-brightness LED digital tube. The voice broadcast module contains a voice playback circuit and a speaker. The sensing module includes a signal receiver for receiving remote control signals. The signal receiver is electrically connected to the LED display module and the voice broadcast module through the main control module. The casing is provided with an indicator light for displaying the status of the sensing module, and the indicator light is electrically connected to the signal receiver.
[0006] By adopting the above technical solution, the voice broadcast module converts the numbers into voice and broadcasts them, making it convenient for users to obtain the meter readings. The sensing module includes a signal receiver for receiving remote control signals, which allows the voice broadcast module to be remotely turned on via the infrared remote control function of a mobile phone without the need for an additional remote control device, making it easy to use. The indicator light (light) can be used to determine whether the signal connection status between the mobile phone and the meter is normal. High-brightness LED light-emitting digital tubes are used, which are low in cost but convenient for observation at night.
[0007] The present invention further includes: the outer casing is provided with operation buttons that are electrically connected to the LED display module and the voice broadcast module respectively.
[0008] By adopting the above technical solution, when there is a problem with the remote control broadcast on the mobile phone or when the user is older and not used to using the mobile phone, the voice broadcast module can be controlled by the operation button located on the bottom of the casing, providing dual operation for convenient use.
[0009] The present invention further comprises: the measurement module including a three-phase SOC metering chip, the main control module including an MCU chip, the MCU chip including a Cortex-M0 / M3 processor, the three-phase SOC metering chip, the operation button, and the sensing module being electrically connected to the input terminal of the processor, and the output terminal of the processor being electrically connected to the LED display module and the voice broadcast module.
[0010] By adopting the above technical solutions, the three-phase SOC metering chip provides the high-precision electrical parameters required by the multi-functional electricity meter, provides parameters for harmonic analysis, and has an anti-theft mode to prevent malicious interference with normal metering. The MCU chip includes a Cortex-M0 / M3 processor, which creates the performance of 32 bits at the price of 8 bits, with low cost, low power consumption and high efficiency.
[0011] The present invention further includes: the MCU chip also includes an LCD, clock management, power management, hardware automatic temperature compensation RTC, ADC, AES and general peripheral interface, and the MCU chip is an HT603X chip.
[0012] By adopting the above technical solution, the main control module uses integrated circuits, which are small in size and multifunctional.
[0013] The present invention further comprises: the data storage module and the communication module being electrically connected to the output terminal of the processor; the communication module adopting the ZigBee module and the Thread protocol.
[0014] By adopting the above technical solutions, the ZigBee module has advantages such as low power consumption, short latency, short range, low cost and high security. The module is small in size, easy to embed, low power consumption, long continuous working time, large networking capacity, and compatibility with multiple industry application protocols. The ZigBee module optimizes power consumption through the Thread protocol, achieving ultra-low energy consumption and easy interconnection with mobile phones. Attached Figure Description
