Embodiment 1

[0020] A battery compensation system after battery undervoltage of a smart meter, such as figure 1 As shown, it is a schematic structural diagram of a battery compensation system in Embodiment 1. This embodiment includes a reference voltage regulator 200, a compensation circuit 300, and a reporting communication module 400. The first input terminal of the compensation circuit 300 is connected to the output terminal of the reference voltage regulator 200, and the compensation The second input terminal of the circuit 300 is connected to the positive pole of the smart meter battery, the third input terminal of the compensation circuit 300 is connected to the home line, the output terminal of the compensation circuit 300 is connected to the positive pole of the power supply electrode 500 of the smart meter and the positive pole of the power supply of the reporting communication module 400, and the reporting communication module 400 After power-on reset, the preset message is sent t...

Embodiment 2

[0025] A battery compensation system after the battery of a smart meter is undervoltage. This embodiment improves the reference voltage regulator 200, such as image 3 As shown, it is a schematic structural diagram of the reference voltage regulator of the second embodiment, as Figure 4 As shown, it is a three-dimensional structural schematic diagram of the reference voltage regulator of the second embodiment. In this embodiment, the reference voltage regulator 200 includes a support 6, a screw 2, a spring, a pressure pad ceramic and a guard plate 4, and the support 6 has a gap. The first side of the notch is the support part 3, and the end surface of the second side of the notch is processed with a blind hole. The first end of the spring is fixed at the bottom of the blind hole. The free length of the spring is greater than the depth of the blind hole. The guard plate 4 is fixed, and the position corresponding to the blind hole of the supporting part 3 is processed with a th...

Abstract

The present invention relates to the technical field of smart electric meter equipment, in particular to a battery compensation system after battery undervoltage of a smart electric meter, including a reference voltage regulator, a compensation circuit and a reporting communication module, the first input terminal of the compensation circuit is connected to the output terminal of the reference voltage regulator , the second input terminal of the compensation circuit is connected to the positive pole of the smart meter battery, the third input terminal of the compensation circuit is connected to the household line, the output terminal of the compensation circuit is connected to the positive pole of the power supply electrode of the smart meter and the positive pole of the power supply of the reporting communication module, and the reporting communication module is powered on and reset Send the preset message to the server through wireless communication. The substantive effect of the present invention is: the compensation circuit can be triggered by the reference voltage regulator when the battery voltage of the smart meter drops to the set voltage, the setting is convenient, the triggering is reliable, and the compensation for the slightly poor voltage quality is provided in a short period of time through the capacitor Power supply, maintain the smart meter to continue to work, and improve the reliability of the smart meter.

Description

technical field [0001] The invention relates to the technical field of smart electric meter equipment, in particular to a battery compensation system after the battery of the smart electric meter is undervoltage. Background technique [0002] The smart meter is the smart terminal of the smart grid. In addition to the basic electricity consumption measurement function of the traditional electric energy meter, the smart meter also has the two-way multi-rate metering function, the user terminal control function, and the two-way data communication function of multiple data transmission modes. , anti-theft function and other intelligent functions. The smart meter has the characteristics of small starting current, no creep, wide load, low power consumption, flat error curve, good stability during long-term operation, small size and convenient installation. Smart meters represent the development direction of energy-saving smart grid end-user intelligent terminals in the future. S...
