The utility model provides an thing networking ammeter based on 4G network, includes intelligent ammeter body, still including setting up in the inside energy control module 100 of intelligent ammeter body. The energy control module 100 includes an on-off control switch 110, and an intermittent triggering module 120. The main function of the energy control module is to intermittently supply power to the communication module. The two ends of the on-off control switch 110 are respectively connected with the power supply module 200 inside the intelligent ammeter body and the power supply input interface of the communication module 300 inside the intelligent ammeter. Such as only one hour of the day, to keep communication clear. Alternatively, two communication periods are set for the day, one at 12 to 12 am and one at half a night from zero to zero. The rest time keeps the power-off state of the communication module, so that the effect of effectively reducing the power consumption can be achieved.
The intermittent triggering module 120 is electrically connected with the on-off control switch 110 to control on-off of the on-off control switch 110. The on-off control switch 110 may be a relay or a triode, or the on-off control switch 110 may be a switching tube. If the relay is a normally open contact or a normally closed contact of the relay can be used as a switch in a power path, and a coil winding of the relay can be used as an input end for signal control. If the power supply is a triode or a switch tube, the triode or the switch tube is connected with a main loop of the power supply channel, and a base electrode of the triode or a control electrode of the switch tube is used as an input end of a control signal.
The intermittent triggering module 120 comprises a controller output interface of the intelligent ammeter and a timing program which is associated with the controller output interface and is arranged inside the controller. The controller is internally provided with a clock module, when the detection time is between 12 and 12, the high level of the output interface of the controller is kept, and then conduction of a triode or a switching tube can be kept, and if the relay is in use, a corresponding driving circuit is required to be arranged to realize control of the relay. The utility model can be set to communicate data in any period of time, and the data can be set according to the actual requirements of users.
