Problems solved by technology
[0003] However, with the continuous increase of electricity consumption, it is inevitable that the mains power supply will be unstable due to excessive load or aging power supply lines, which will affect the normal use of household appliances and even affect the service life.
Therefore, at present, people usually use the mains monitoring system to monitor the changes of the mains. However, the current mains monitoring system is mainly composed of a mains rectifier unit, a mains voltage sampling unit, and a signal power amplifier isolation unit. The signal power amplifier isolation unit is usually comp

Embodiment 1
[0033] figure 1 Shown is a structural block diagram of the existing emergency power mains high-speed monitoring system 10 provided by the first embodiment of the present invention. Such as figure 1 As shown, in the prior art, the auxiliary power supply is set in the control unit, and the control unit is generally an isolated low-voltage power supply, while the power supply required by the signal power amplifier isolation unit 104 is a non-isolated high-voltage power supply, so the circuit of the auxiliary power supply must be low-voltage. The voltage becomes a high voltage isolation design, which increases the complexity of the control unit.
[0034] figure 2 Shown is the structural block diagram of the emergency power mains high-speed monitoring system 10 provided by the first embodiment of the present invention; figure 2 As shown, the emergency power mains high-speed monitoring system 10 according to the first embodiment of the present invention includes:

The invention discloses an emergency power supply mains supply high-speed monitoring system which comprises a mains supply rectifier unit for receiving a mains supply voltage signal and rectifying the mains supply voltage signal to obtain a pulsating direct current voltage signal, a mains supply voltage sampling unit for obtaining a sampled pulsating direct current voltage signal through the voltage sampling of a pulsating direct current voltage signal, a synchronous assisted power supply unit for receiving the pulsating direct current voltage signal and obtaining a stable pulsating direct current voltage signal through voltage stabilizing processing, a signal amplifier isolation unit for carrying out power amplification isolation processing on the sampled pulsating direct current voltage signal, obtaining a pulsating direct current voltage signal which is subjected to power amplification isolation, and outputting the pulsating direct current voltage signal which is subjected to the power amplification isolation. According to the emergency power supply mains supply high-speed monitoring system, the design of the synchronous assisted power supply unit is employed, mains supply is directly supplied to the signal amplifier isolation unit via the synchronous assisted power supply unit, the circuit structure is simple, and the connection is simple.
Description
technical field [0001] The invention relates to the field of electronics, in particular to the field of commercial power monitoring systems. Background technique [0002] Electric energy is a convenient energy source, and its wide application has formed the second technological revolution in the modern history of mankind. It has effectively promoted the development of human society, created huge wealth for human beings, and improved human life. With the popularization of the power grid, household appliances are now used in every household, which has brought great changes to human life. [0003] However, with the continuous increase of electricity consumption, it is inevitable that the mains power supply will be unstable due to excessive load or aging power supply lines, which will affect the normal use of household appliances and even affect the service life. Therefore, at present, people usually use the mains monitoring system to monitor the changes of the mains. However,...
