Multifunctional electric meter with delayed alarm function

Abstract

The invention discloses a multifunctional electric meter with a delayed alarm function. Aiming at the problems that the safety is low, the alarm effect is poor and the residual electric quantity cannot be refreshed in time, the following scheme is provided: the multifunctional electric meter comprises electric meter equipment, and the electric meter equipment comprises a hardware module and a control system which is arranged inside; and the control system comprises a communication module, a calibration module, a time delay module, a monitoring module and an alarm module, wherein the alarm module is connected with the monitoring module, the alarm module is further connected with the time delay module, a control chip is arranged in the control system, the communication module is connected with the control chip in the control system, and the control chip is also connected with the monitoring module, the calibration module, the delay module and the alarm module. According to the invention, the delayed reminding on the networked alarm module is started, the interface jumps to the functional area of the alarm of the mobile phone end, the specific time can be set to remind the user again, the reminding efficiency is high, and the use effect is better.

Description

technical field [0001] The invention relates to the technical field of multifunctional electric meters, in particular to a multifunctional electric meter with a delay alarm function. Background technique [0002] At present, when the multi-function ammeter is working, the voltage is divided by the resistor, and the current is sampled on the sampling resistor by the current transformer, and then sent to a dedicated power chip for processing, and converted into a digital signal and sent to the CPU for calculation. Due to the use of a dedicated power processing chip, the resolution of voltage and current sampling is greatly improved, and there is enough time to measure power more accurately, so that the measurement accuracy of the power meter has been significantly improved. The CPU is used for time-sharing billing and processing various input and output data. It reads out the data of the dedicated energy chip through the serial interface, and completes the time-sharing active ...

AI Technical Summary

Problems solved by technology

[0004] 1. The traditional multi-function meter with delay alarm function can only realize the alarm operation on the meter, and cannot timely and effectively alarm

[0005] 2. The existing electric meter hardware materials are relatively common, and the safety is low during use;

[0006] 3. After the existing electricity meter finishes recharging the user card, the display data cannot be refreshed in time, resulting in discrepancies in the remaining power display
