1, there is a power accumulation register in the chip, which can provide divided phase, combined active and reactive power, but does not provide the grid cycle accumulation mode. Through the energy pulse generator, the chip provides the calibration pulse CFl and the low-frequency pulse F1 / F2 that drives the stepper motor.
2, the power metering chip is an electronic component used to measure the electrical power in the power system. It typically contains one or more sensors that measure current, voltage, and power factors and convert this information into a digital signal.
3, it uses the current transformer to measure the current, the voltage transformer to measure the voltage. Both current transformers and voltage transformers are measured by the principle of magnetic induction. Electronic energy meters also need power metering chips to achieve digital metering and data processing.
4, measurement chip. The metering chip is the core of the metering part of the smart meter. The sampling dynamic range and reference temperature coefficient of the chip are directly related to the ability of the smart meter to withstand the shock load and the operation stability. An excellent metering chip can make the calculation of the data more accurate.
1. Use special tools to open the shell of the meter and remove the meter core. Connect cables to the new meter core. Ensure that cables are correctly connected according to the position of the original chip. Insert the meter core Insert the new meter core into the meter base and ensure that it is securely secured. Check the meter core Close the meter shell, turn on the power, and check whether the new meter core is working properly.
2, first turn on the meter. Take the card that has been recharged. The chip goes in facing out against the card slot. A "ding" is heard, and the charge in the card is automatically recharged to the meterIt's here. Electric card: An instrument similar to an IC card that records electricity consumption. The amount of electricity purchased is stored on the card, which is inserted into the meter to recharge the electricity.
3, the correct card insertion method: hold the meter card, the card gap up, smoothly inserted into the jack, with a chip can be inside, the demonstration figure is as follows: After installing the smart IC card meter, the power supply department for the user to replace the meter to provide preset electricity charges. After installation and connection, they can start using electricity.
4, its products are used in general micro-control unit (MCU), Type-C interface control chip, camera anti-shake controlChip, touch chip and smart meter control chip. The product also serves the Internet of Things (IoT), new energy vehicles, artificial intelligence and other markets. The company conducts business through its subsidiaries.
5. This card is embedded with a chip and is the medium through which you "communicate" with the smart meter. Remember to insert the card into the card slot of the meter and make sure it is in close contact. When the meter's display displays the words "read the card successfully", your electricity bill has been charged to the meter, and the smart meter can work normally.
6, LCD or LED and liquid crystal driver chip constitute the display partPlated with electrodes and welded with leads.
Role of crystal oscillator: Universal crystal oscillator, used in various circuits to produce oscillation frequencies. A quartz crystal resonator used in conjunction with other components to produce a standard pulse signal, widely used in digital circuits. Quartz crystal resonators for microprocessors. CTVVTR with quartz crystal resonator.
The crystal oscillator plays a role in providing a stable clock signal in the circuit. The clock signal is one of the very important signals in electronic devices, which is used to synchronize the work of various circuit modules and ensure that they operate in the correct time series.
The general crystal excitation is to produce oscillation, crystal vibration has different frequencies, can make the circuit work in a stable frequency range, it is the vibration device for the integrated circuit, crystal vibration is the pace benchmark, stable frequency, select frequency.
