  • the rear gateway 30 can manage any number of tandem control devices 20 connected in series with the lamps, so as to form scene control, that is, through the cloud or the app, it is possible to implement a combination of switch control for many lamps, for example, there are 10 lamps, In some scenarios, lights 1, 3, 5, 7, and 9 need to be turned on, others are off, and lights 2, 4, 6, 8, and 10 are also turned on in some time periods to achieve preset presets. Group scene control function.
  • the present invention provides a circuit control method, which is characterized by including steps:
  • the series control device 20 controls the operation of a load 100 in series according to the control signal.
  • circuit control method of the present invention a method of transmitting a control signal by self-generating power and a method of controlling the load 100 in series are combined, so that the advantages of self-generation and series control can be combined with each other, and the control signal can be completely received. To achieve sensitive control.
  • a pairing code may be sent, so that both ends of the control can be accurately paired with the control, that is, the controlling end corresponds to the controlled end.
  • the control signal is received without sleep, so that the transmitted control signal can be completely received, and the control signal can be received at the long or the end.
  • the series control device 20 when the load 100 is in a non-operation state, the series control device 20 is in a low-power operation state.
  • the current or voltage parameter in the circuit is monitored, a second half-cycle control element 212 is turned off at a predetermined interval, and a second half-cycle control element 212 is obtained.
  • the power on the side is used for a sleepless communication unit 23 to work.
  • the power supplied to the sleep-free communication unit 23 is adjusted to make it work at low power.
  • the step of controlling the operation of the load 100 in series by the series control device 20 includes controlling the operation of the load 100 by a local switch 26 at one end of the series control device 20.

Abstract

La présente invention concerne un système de commande de circuit et son procédé de commande, et un dispositif de commande en série (20). Le système de commande de circuit est configuré pour accéder à un circuit de charge (100) et commander le fonctionnement de la charge (100), et comprend : un dispositif de commande mobile (10) destiné à générer et transmettre automatiquement un signal de commande ; et un dispositif de commande en série (20). Dans le circuit de charge (100), le dispositif de commande en série (20) est connecté en série avec la charge (100), et le dispositif de commande en série (20) reçoit le signal de commande afin de commander le fonctionnement de la charge (100). Selon le système de commande de circuit et son procédé de commande, et le dispositif de commande en série (20), lorsqu'une charge (100) ne fonctionne pas, un faible courant est commandé pour passer à travers la charge (100), de manière à réduire l'impact sur la charge (100).
