With reference to the accompanying drawings embodiments of the invention are further described:
As shown in Figure 1, colliery of the present invention Mobile life-saving capsule backup battery electricity saving method basic process is as follows:
The current battery electric quantity of detection system, as step S110 in figure; Judge that the more current battery electric quantity of system, whether lower than a default low electric weight activation threshold value, refers to be equal to or less than herein, below identical, as step S120 in figure; If so, send a low capacity prompt signal, so as by system according to this low capacity prompt signal setting battery saving mode, step S130-S140 in figure; If not, continue the current battery electric quantity of detection system, until the current battery electric quantity of system is while triggering Fujian value lower than this low electric weight, then according to step S130-S140 in figure, battery saving mode is set.Specific implementation process is as follows:
The method starts from step S110, and this step 110 is in order to the current battery electric quantity of detection system.The current battery electric quantity of system here specifically can percentage, estimate that the formal intuition ground such as up duration represent, and do not repeat them here.
In step S110, how to carry out the current battery electric quantity of detection system, generally by power management chip, to monitor and control, it calculates battery electric quantity by the cell voltage detecting in battery discharge procedure.For example, voltage during the full electricity of general lithium ion battery is 4.2V left and right, and discharge cut-off voltage is 2.7V left and right, therefore only need to know current cell voltage when survival capsule is used, and just can converse the theoretical residual capacity of battery.By the battery voltage monitoring module to system, detection system current electric quantity easily just.When the dump energy of battery lower than some levels other time, just can take corresponding power saving measure by prompt system, avoid thus causing larger secondary disaster generation because battery electric quantity exhausts.
After the current battery electric quantity of the system that detects, in step S120, judge that whether the current battery electric quantity of system is lower than low electric weight activation threshold value.This low electric weight activation threshold value can preset, for example, be preset as 25%, 45%, 65%, 85% etc. of the total electric weight of battery, generally selects such grade setting can meet the needs of survival capsule protection.When the current battery electric quantity of system is during lower than electric weight rank corresponding to this low electric weight activation threshold value, by automatically entering corresponding battery saving mode, make user without being constantly concerned about battery dump energy, so just relatively meet the requirement of human oriented design.
Step S120 judge the current battery electric quantity of system lower than low electric weight activation threshold value after, in step S130, will correspondingly send low capacity prompt signal.The form of this low capacity prompt signal can be the signal of telecommunication, it is as control command, triggering system enter some preset battery saving modes and by the definition of this battery saving mode default revise the subsystem switch relevant to system power consumption and power consumption equipment on off state.
