Portion's instruction or the instruction of information issuing system itself carry out the control of power supply.For example, in campus, work as information issuing system
Electronics class board is used as in campus in use, according to scheme described in embodiment two, information issuing system will be located during at school
In the state of closing, however certain Tian You leading body at a higher level carries out inspection work to school, opens letter during just needing at school at this time
Delivery system is ceased, we can be according to the scheme described in the present embodiment, by receiving information issuing system or external server
The mode of instruction power module 306 controlled.
In the above embodiments, battery saving arrangement can be built in the inside of information issuing system.In addition, information is issued
System native can be sent to energy saver by RS-232, RS-485, USB communication interface and be instructed.
Fig. 4 show according to embodiments of the present invention four shown in a kind of power-saving control method stream for information issuing system
Cheng Tu.As shown in figure 4, a kind of power-saving control method for information issuing system, comprising:
S401 obtains reference clock, and reference clock is sent to control module;
S402 is based on reference clock, judges whether to need to carry out control system of switching on or off electricity to power module;
S403 receives the control signal of control module, the power switch of information issuing system is opened or closed.
Specifically, after obtaining reference clock further include:
The opening time point and shut-in time point of setting information delivery system.
Specifically, it is based on the reference clock, judges whether to need to carry out control system of switching on or off electricity to power module, comprising:
Judge whether the opening time point and shut-in time point of the reference clock received and setting are consistent, work as reference clock
When consistent with opening time point, the control signal of opening imformation delivery system is sent to power module;When reference clock and close
When time point is consistent, the control signal of closing information delivery system is sent to power module.
Particularly, power module includes: motherboard power supply module and display screen power module.
Specifically, it is being based on reference clock, before judging whether to need to carry out control system of switching on or off electricity to power module, also wrapped
It includes:
The instruction of information issuing system or external server is received, and the power module is controlled according to the instruction
System.
It can be seen from the above description that the above embodiments of the present invention realized the following chievements:
Present invention is mainly used for the Energy Saving Control to information issuing system, in the different use occasions of information issuing system,
The time can be opened and closed by being arranged in advance, flexibly to control the use of information issuing system;Since it is same with clock
Module is walked, the opening and closing time of information issuing system can be accurately controlled;Thus both reached to issue information and has been
