Abstract

The invention discloses a power-saving method of telltale clock, which can turn off the power supply of telltale clock processor in dormancy state. The method comprises using a single chip to set the time regions of telltale clock dormancy state and revival state, providing a controller connected with the single chip and a power supply manager, which can input command into the power manager when there is input signal at an input terminal or a timer of the telltale clock reaches a preset time region, to enter the telltale clock into dormancy state or revival state, and turn off the single chip, LCD screen and indication lamps in dormancy state, to eliminate the energy consumption at dormancy state of telltale clock.

Description

A kind of power-saving method of telltale clock

Technical field

The power-saving method of telltale clock of the present invention relates in particular to a kind of telltale clock power-saving method by the sleep mode economize on electricity.

Background technology

Telltale clock has a wide range of applications in factory, company as a kind of work attendance instrument, in the prior art, telltale clock generally needs work round-the-clock, this mode is consume electric power not only, and can shorten life-span of telltale clock, some telltale clock also has certain sleep mode, but because dormant state not thoroughly (such as processor and pilot lamp is still in running order or half duty).Still there are the consume electric power and the defective in shortening telltale clock life-span.

Summary of the invention

The objective of the invention is to overcome above-mentioned defective of the prior art, provide a kind of dormant state can close check card in the power-saving method of processor power supply.

Power-saving method in a kind of telltale clock of the present invention may further comprise the steps: the power-saving method that a kind of telltale clock is provided, described telltale clock comprises time set, single-chip microcomputer, entry terminal, the electric power controller that links to each other with described single-chip microcomputer and the LCD display that links to each other with described electric power controller, pilot lamp, and this power-saving method may further comprise the steps:

Provide a control device to link to each other with described single-chip microcomputer respectively and electric power controller links to each other;

Setting single-chip microcomputer by entry terminal enters the time period of dormant state and enters the time period of wake states;

Described time set or entry terminal produce the dormancy input signal, and are sent to control device;

Described control device receives the dormancy input signal of described time set or entry terminal, notifies described single-chip microcomputer to prepare dormancy;

Described single-chip microcomputer sends feedback signal to described control device after entering dormant state;

Described control device produces a control signal, orders described electric power controller to close the power supply of described single-chip microcomputer, LCD display and pilot lamp.

This power-saving method also comprises the steps:

Described time set or entry terminal produce the input signal of reviving, and are sent to control device;

Described control device receives the input signal of reviving of described time set or entry terminal, produces a control signal and is sent to described electric power controller;

Described electric power controller produces the power supply of the described single-chip microcomputer of the described electric power controller conducting of a control signal order, LCD display and pilot lamp.

Described control signal is a kind of level variable signal, and when level signal was a kind of state in high level or the low level, electric power controller was closed the power supply of described single-chip microcomputer, LCD display and pilot lamp; And when level signal is another kind of state in high level or the low level, the power supply of the described single-chip microcomputer of electric power controller conducting, LCD display and pilot lamp.

The present invention has following advantage: telltale clock of the present invention is owing to be provided with control device, and when being in dormant state, telltale clock closes the power supply of single-chip microcomputer, LCD display and pilot lamp by the mode of cutting off, eliminate the energy consumption of telltale clock, reach the purpose of economize on electricity in dormant state.

Fig. 1 is the structured flowchart of telltale clock;

Fig. 2 is the dormancy process flow diagram of telltale clock power-saving method;

Fig. 3 is the process flow diagram of reviving of telltale clock power-saving method.

Embodiment

With reference to Fig. 1, be the structured flowchart of telltale clock, comprise a time set, an entry terminal, a control device, a single-chip microcomputer, an electric power controller and LCD display and pilot lamp, the electricity-economizing method when telltale clock enters dormant state may further comprise the steps:

Provide a control device to link to each other with single-chip microcomputer respectively and electric power controller links to each other;

Time set (according to the Single Chip Microcomputer (SCM) program instruction) or entry terminal (manual mode) produce the dormancy input signal, and are sent to control device;

Control device receives the dormancy input signal of described time set or entry terminal, notifies described single-chip microcomputer to prepare dormancy;

Single-chip microcomputer sends feedback signal to described control device after entering dormant state;

Control device produces a control signal, orders described electric power controller to close the power supply of described single-chip microcomputer, LCD display and pilot lamp.

The electricity-economizing method of telltale clock when dormant state enters into wake states may further comprise the steps:

Time set (according to the Single Chip Microcomputer (SCM) program instruction) or entry terminal (manual mode) produce the input signal of reviving, and are sent to control device;

Electric power controller produces the power supply of the described single-chip microcomputer of the described electric power controller conducting of a control signal order, LCD display and pilot lamp.

With reference to Fig. 2, dormancy process flow diagram for telltale clock power-saving method shown in Figure 1, at first, the user can import sleep signal by entry terminal, perhaps the time set of telltale clock is when the predefined dormancy time section of pointed, can import sleep signal automatically, sleep signal notice single-chip microcomputer is prepared dormancy, when single-chip microcomputer is carried out the dormancy preparation, return feedback signal, control device promptly produces control signal, closes single-chip microcomputer, LCD display and pilot lamp power, and telltale clock enters dormant state immediately.

With reference to Fig. 3, the process flow diagram of reviving for telltale clock power-saving method shown in Figure 1, at first, the user can be by the entry terminal input signal of reviving, perhaps the time set of telltale clock is when the predefined recovery time section of pointed, the input signal of reviving automatically, and control device promptly produces control signal, open single-chip microcomputer, LCD display and pilot lamp power, telltale clock enters duty immediately.

Claims
