The invention discloses a standby power supply system of online monitoring equipment and a method of the standby power supply system. The standby power supply system comprises a first power supply, a relay, a multifunctional power meter and intelligent monitoring equipment, wherein the first power supply comprises a power taking coil and rectifier-filter equipment; the power taking coil is in induction connection with a circuit for obtaining power from the circuit; the rectifier-filter equipment is connected with the power taking coil and is used for rectifying and filtering power obtained from the circuit and converting the power into stable power; the first power supply is connected with a power supply terminal of the multifunctional power meter through the relay; and the intelligent monitoring equipment is in communication connection with the multifunctional power meter and is used for obtaining information that the multifunctional power meter obtains the power from a second power supply. The intelligent monitoring equipment is in communication connection with the relay and is used for controlling the relay to connect the first power supply and the power supply terminal of the multifunctional power meter through the relay when the second power supply is offline. By the standby power supply system, the problem that information collection is inaccurate since the power meter is offline is solved; and the electricity is prevented from being stolen.
Description
technical field [0001] The invention relates to a standby power supply system and a method for on-line monitoring equipment. Background technique [0002] In the monitoring and monitoring of the power system, the electric energy meter is responsible for monitoring and measuring various data information inside the circuit, such as voltage, current and power consumption, etc., due to the long-term operation of electronic products, frequent crashes or malicious stealing of electricity, etc. Other reasons will cause the energy meter to be offline, which will affect the success rate of collection and lead to inaccurate monitoring results. [0003] The multi-functional electric energy meter is used in the present invention, and the electric energy meter includes but not limited to current and voltage sensors and electric energy metering devices. Contents of the invention [0004] In order to solve the above problems, the present invention provides a backup power supply system f...
