Abstract
The invention relates to a flashlight charge control method, which uses a main control chip and comprises: judging whether a flashlight is charged or is cut off in a charging state through a charge voltage detection unit which is electrically connected to the main control chip; and if so, allowing the main control chip to output a control signal to a pulse width modulation (PWM) driving module to drive the flashlight to perform emergency illumination according to a 1/N normal illumination duty ratio requirement or a permission, wherein N is 2 preferably. The flashlight charge control method detects and judges whether the flashlight is charged on automatically in a charging state or is cut off in a charging state through a control program and a circuit; meanwhile, the PWM duty ratio is regulated to realize low power-consumption emergency illumination, so that the use by a user is very convenient.
Description
Technical field
The present invention relates to military/police uses torch, is specifically related to a kind of torch charge control method.
Background technology
At present, military/police is widely used in the public security system with torch, and military/police need guarantee that with torch personnel can use torch and service time thereof constantly.Therefore, military/alert with torch use the back, the use age must not be connected with charger all the time, the moment guarantees the internal cell Full Charge Capacity.But prior art has following shortcoming:
1, in a single day have a power failure night, the user is difficult to find, and also can do nothing to help the user and brings all objects of going out on missions in the dark;
If 2 brightness during with normal use are luminous, be difficult to guarantee that torch normally uses.
Summary of the invention
The technical issues that need to address of the present invention are how to provide a kind of torch charge control method, the use problem on obstacle in the time of tackling electricity failure at night.
The technology of the present invention problem solves like this: make up a kind of torch charge control method, utilize main control chip, may further comprise the steps:
Judge whether in charging or keep under the charged state to cut off the power supply by the charging voltage detecting unit that is electrically connected with described main control chip;
If described main control chip is exported by the normal illumination duty ratio requirement of 1/N or is assented and permitted to export control signal to the emergency lighting of pulse width modulation (PWM) driver module driving torch, 1.5＜N＜10.
According to charge control method provided by the invention, also comprise: the emergent control switch state that described main control chip detects its electrical connection is to allow described control signal output when allowing closure, otherwise forbids output.
According to charge control method provided by the invention, described emergent control switch is magnet ring switch, key switch or inductive switch.
According to charge control method provided by the invention, also comprise: the charging voltage that described main control chip detects its electrical connection judges whether to be in charged state.
According to charge control method provided by the invention, preferred N=2.
According to charge control method provided by the invention, described torch LED is a high-powered LED lamp, and this torch also is provided with one or more luminescence-utraviolets LED lamp.
Torch charge control method provided by the invention, by control program and circuit, detection judges whether in charging or keeps under the charged state to cut off the power supply, and is to light torch automatically, adjust the PWM duty ratio simultaneously and realize the low power consuming emergency lighting, the personnel that are very easy to use.
Description of drawings
Further the present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the alert torch electrical block diagram of using in the specific embodiment of the invention.
Embodiment
As shown in Figure 1, the alert torch of using of the specific embodiment of the invention is on the basis of F90 torch on duty, append and detect and control section, it adopts main control chip U6, this main control chip U6 is electrically connected the change in voltage that link CD1 detects charging port J1, main control chip U6 output MAIN_LED output control signal is given field effect transistor switch Q1, control its conducting or by, realize driving the PWM change in duty cycle of king light D8.This torch also is provided with one group of magnet ring switch 1 that is used to carry out function selecting and one group of luminescence-utraviolet LED lamp D9, D10 and D11.
This alert operation principle with torch is as follows:
Read the state of charging port J1 by main control chip U6, can learn and whether charge that magnet ring switch 1 is placed on any gear and charges, main control chip U6 must close normal illumination output.
When state 1 → 0 back of charging port, when keeping 0, following action is arranged then:
If 1 set of ㈠ magnet ring switch is then opened king light D8 in emergency light function shelves,, be 1 just to close up to rotating switch or charging port state with 50% illumination work;
If ㈡ magnet ring switch 1 is in other gear, the charging port state is 1 → 0, and then king light continues to close, and waits for that rotating the magnet ring switch changes the corresponding gear of waking up.
In addition, this police is provided with cradle with torch, and torch contacts bottom the way of contact of cradle includes, but are not limited to torch or the contact of torch stack shell top.
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
Claims (6)
1. a torch charge control method is characterized in that, utilizes main control chip, may further comprise the steps: judge whether in charging or keep under the charged state to cut off the power supply by the charging voltage detecting unit that is electrically connected with described main control chip;
