Title:
ALARMING SYSTEM, CONTROL METHOD THEREFOR, AND ENERGY STORAGE UNITS THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/143748
Kind Code:
A1
Abstract:
The present invention provides an alarming system, comprising: a control unit; buses; a plurality of terminal components connected to the buses, the control unit communicating with the terminal components by means of the buses and supplying power to the terminal components; and a plurality of energy storage units connected to the buses, each energy storage unit being configured to supply power to at least one of the terminal components. According to embodiments of the present invention, the situation that a bus loop of the system is low in power consumption in a monitoring state, and is large in current in an alarm state and a linkage start state is changed, and the power consumption of the bus loop can be kept small and constant. On-site components only need a weak current in most of the time, energy accumulation can be performed with a small current for a long time by means of the charging of the energy storage units, and power is supplied by the energy storage units under the condition that the current is large in the alarm state and the linkage start state. The reduction of pressure drop on the bus loop allows the bus loop to be longer and the number of loaded components to be larger. Because the power consumption of the bus loop is reduced and balanced, the anti-electromagnetic interference capability of the bus loop is greatly strengthened.
