Laser pen provided by the invention also comprises alarm unit, and it is connected with the output terminal of charging control unit 4, control of discharge unit 3 and main control unit 5 simultaneously.When charging control unit 4 detects battery 2 charging when abnormal, it sends order-driven alarm unit and reports to the police, and sends instruction simultaneously and disconnects battery 2 and stop to battery 2 chargings; In like manner, control of discharge unit 3 detects battery 2 electric discharge when abnormal, drives alarm unit report to the police and stop discharging; When main control unit 5 detects, open laser pen when abnormal, main control unit 5 drives alarm units to report to the police.Concrete; when main control unit 5 is subject to the open command of second switch 8; if it is not during for holding state (not both being recharged electric discharge) that main control unit 5 is found batteries 2 yet; in order to protect laser pen; main control unit 5 is not opened laser pen; it gives the alarm by alarm unit simultaneously, to notify user's laser pen temporarily can not open.
The present invention also provides a kind of open method of the laser pen with portable power source, and it comprises the following steps successively:
S1, main control unit detect to judge whether it receives the order of opening laser pen, if so, performs step S2, if not, continue to detect judgement; Be that main control unit detection judges whether that the button that user presses on laser pen sends the order of opening laser pen;
S2, main control unit send instruction makes the charging control unit in portable power source start to detect the state of battery and judge according to the state detecting whether battery is being recharged, simultaneously, main control unit sends instruction makes control of discharge unit in portable power source start to detect the state of battery and judge according to the state detecting whether battery is discharging, i.e. main control unit order charging control unit and control of discharge unit inspection also judge the state of battery;
The result of S3, main control unit combined charge control module and control of discharge unit judges judges that battery, whether in not both being recharged also the not state of electric discharge, if so, carries out S4, if not, returns to step S1;
S4: main control unit sends instruction and opens laser pen, main control unit sends closed the first switch of instruction, so that battery is powered to laser light emitting device.
So the open method of laser pen provided by the invention can be controlled and realize laser light emitting device only at the steady timing working of driving voltage, only at battery, just work during in standby.Can guarantee the stable operating voltage of laser light emitting device like this, and then make the safe and reliable of laser pen, also extend the life-span of laser light emitting device and laser pen.Meanwhile, in conjunction with portable power source, the battery of laser pen need not be changed, also increased the life-span of laser pen.
Preferably, between rapid S1 and S2, also comprise: wait for after predetermined amount of time, main control unit again detects and judges whether it receives the order of opening laser pen, if so, performs step S2, if not, returns to step S1.If extraneous careless triggering pressed time button (being second switch), if maloperation, conventionally second switch can rebound and return to continue to remain open state, by time delay detection, second switch can be detected in off-state, it is bright that main control unit does not make laser pen, if be really user, by second switch, send the order of opening laser pen, after very little time period of main control unit time delay one, still the open command that second switch sends can be detected.Therefore laser pen provided by the invention can avoid maloperation to open the danger that laser pen brings.Preferably, step S3 also comprises simultaneously: when being judged as NO, when returning to step S1, main control unit sends order-driven alarm unit and reports to the police, and to user, sends and opens abnormal warning, so that user knows the state of laser pen.
In conjunction with the embodiment shown in Fig. 5, illustrate that its course of work is as follows: first, execution step S11, main control unit detects and judges whether it receives the order of opening laser pen, now, if there is button to press, send open command, execution step S12, if not, continue to detect judgement, step S12, waits for after 200MS, and main control unit again detects and judges whether it receives the order of opening laser pen, if so, performs step S13, if not, returns to step S11, while the order of opening laser pen still being detected, represent the non-maloperation of this open command, start to perform step S13: in main control unit, single-chip microcomputer output high level drives charging control unit and control of discharge unit to start to detect the state of battery, the result feedback that charging control unit judges detection is to main control unit, and control of discharge unit by the result feedback detecting to main control unit, then perform step S14: whether main control unit judges battery in holding state according to the judged result that receives charging control unit and control of discharge unit feedback, if, execution step S15, main control unit output high level command makes the first switch closed, thereby battery is connected to laser light emitting device, laser pen is bright, simultaneously main control unit can not charge portable power source by control signal can not to discharge to external world.If the battery of main control unit judgement is not above in holding state, it returns to step S11 continuation and detects the order that judges whether to open laser pen, simultaneously, main control unit can be controlled the charging and discharging state of charging control unit and/or control of discharge unit, and, main control unit sends order-driven alarm unit and reports to the police, to tell user to open extremely.After laser pen is bright, if main control unit detects the order (be second switch closed) of closing laser pen, single-chip microcomputer output low level, main control unit sends instruction and disconnects the first switch, and laser pen goes out.
The input end of main control unit can detect in several ways and judge whether user sends the order of opening laser pen.Because second switch is preferably hand switch, the order of opening laser pen realizes by closed second switch, therefore main control unit detects, judges that its order that whether receives unlatching laser pen is to judge that by detection whether second switch is closed.More preferably, one end ground connection as the hand switch of second switch, therefore preferably, detect judge second switch whether closure be to judge whether ground connection of the terminal that is connected with second switch on main control unit by detection, i.e. detection judges whether this terminal has ground signalling input.
Because discharge and recharge, can make cell voltage have obvious fluctuation, so battery discharges to external world or be subject to the process of extraneous charging to separate use with the process that laser pen sends laser, can avoid laser light emitting device to damage because of spread of voltage in when work, thus the life-span that can improve laser pen.The shell of laser pen provided by the invention can be made the shape of conventional pen, also can make the shape of conventional portable power source, and it can have the function of laser pen and portable power source simultaneously.
