Abstract

The invention relates to the field of agricultural appliances, and provides a handheld four-stroke engine having a time reminding function. The handheld four-stroke engine comprises a handheld four-stroke engine starting device, wherein the starting device is connected with a timer; the timer is connected with a central processing unit; the central processing unit is connected with a displayer and a warner; the timer has timing and comparing modules; the timing module returns the time length and the comparing result to the central processing unit; the central processing unit sends the signal to the displayer; and when the working time reaches the set time, the warner is controlled to give an alarm. The handheld four-stroke engine having the time reminding function can remind operators to take turns or take a rest after one hour of work; the preferable timer having a cross lock can enable a special person to set the working time of the handheld four-stroke engine; and a preferable delayer can enable the effect of the timer to be prolonged a certain time in a power failure state. The handheld four-stroke engine is simple in structure and high in cost performance, largely improves the safety, and effectively protects the people life safety.

Description

A kind of hand four stroke engine with time alert feature

Technical field

The present invention relates to agricultural mechanical field, be specifically related to a kind of hand four stroke engine with time alert feature.

Background technique

Existing hand four stroke engine function has been that function is comparatively complete, protective measure also quite puts in place, but hand four stroke engine or machinery after all, and mostly need artificial direct control, just as it's four hours can not past driving, the muscle power of at substantial is needed in machine work process, long work easily produces visual fatigue and the stiff numbness of arm, the generation of accident also happens occasionally, remind to each operation setup regular hour for this reason, and the operating time should be set according to the environment of work, only work function is forced in setting if desired, the life safety of such guarantee operator and workmanship.

Summary of the invention

The invention provides a kind of that can remind operating time with force only work to prevent excessive exercise and tired hand four stroke engine system for prompting.

For this reason, provide a kind of hand four stroke engine with time alert feature, comprise hand four stroke engine starting drive, described starting drive is connected with timer, and timer connects central processing unit (CPU), and central processing unit (CPU) is connected with display device and alarm;

Described timer has timing and contrast module, and duration, comparing result are fed back to central processing unit (CPU) by timing module, and signal is transmitted in display device by central processing unit (CPU), reach the time of setting when operating, control alarm equipment alarm.

Above-mentioned timer generally sets the time of fire alarming of hour.

Described starting drive and timer are connected with timer.

Described timer is with electronic password lock.

Described timer is with the delayer controlling this timer delay power.

Beneficial effect of the present invention: the invention provides a kind of hand four stroke engine with time alert feature, comprise hand four stroke engine starting drive, described starting drive is connected with timer, and timer connects central processing unit (CPU), and central processing unit (CPU) is connected with display device and alarm; Described timer has timing and contrast module, duration, comparing result are fed back to central processing unit (CPU) by timing module, signal is transmitted in display device by central processing unit (CPU), the time of setting is reached when operating, control alarm equipment alarm, can work operator and one littlely remind this rotation or rest constantly, the timer of preferred having electronic electronic password lock can allow special messenger set the operating time to hand four stroke engine, in addition preferred delayer, can make the effect off-position of timer extend certain hour.Structure is simple, cost performance is high, substantially increases Security, the available protecting life safety of people.

Accompanying drawing explanation

Fig. 1 is function schematic block diagram of the present invention;

Description of reference numerals: starting drive 1; Timer 2; Display device 3; Alarm 4; Electronic password lock 5; Timer 6; Delayer 7; Central processing unit (CPU) 8.

Embodiment

Embodiment one;

As shown in Figure 1, have a hand four stroke engine for time alert feature, comprise hand four stroke engine starting drive 1, described starting drive 1 is connected with timer 2, timer 2 connects central processing unit (CPU) 8, and central processing unit (CPU) 8 is connected with display device 3 and alarm 4;

Described timer 2 has timing and contrast module, and duration, comparing result are fed back to central processing unit (CPU) 8 by timing module, and signal is transmitted in display device 3 by central processing unit (CPU) 8, reach the time of setting when operating, controls alarm 4 and reports to the police.

The program solves, and works long hours and causes numbness and fatigue, easily produces the problem of contingency, and setting certain hour carries out the problem of reporting to the police.

Embodiment two, and by reference to the accompanying drawings 1;

On the basis of embodiment one, described starting drive 1 and timer 2 are connected with timer 6.

Described timer 6 is with electronic password lock 5, and object is time-controlled object to realize, and realizes timing personal management, prevents from opening voluntarily.

Described timer has the function of set time starter/stopper 1, plays the effect forcing to stop work.

Described timer 6 is with delayer 7;

Described delayer 7 function is the off-position of timer to extend, and general prolongation half an hour was by one hour.

Reminding alarm system on the basis of embodiment one; the timer of preferred having electronic cipher lock can allow special messenger set the operating time to hand four stroke engine; timer can be forced after four hours to stop work in work; in addition preferred delayer; the effect off-position of timer can be made to extend certain hour, and darker one deck protects life safety.

More than exemplifying is only illustrate of the present invention, does not form the restriction to protection scope of the present invention, everyly all belongs within protection scope of the present invention with the same or analogous design of the present invention.
