The electronic stopwatch can conduct simple timing and is easy in operation, accurate in measurement and intuitional in display.

Description

Electronic stopclock

Technical field

The utility model belongs to communication technical field, is specifically related to a kind of electronic stopclock.

Background technology

Stopwatch is the desirable time keeping instrument of industrial automation control, national defence, laboratory and R﹠D institution, and it is widely used in various relays, electromagnetic switch, the time test of device, timer etc. when controller, the court of a feudal ruler.Present employed electrical secondmeter is pointer-type or integrated circuit type mostly, the structure relative complex, measure inaccurate, shortcoming such as volume is too big.

Summary of the invention

The purpose of this utility model provides electronic stopclock, and by Single-chip Controlling, it is little that single-chip microcomputer has a volume, cost is low, and antijamming capability is strong, can realize advantages such as each distributed control of extension set, the design of this electronic stopclock is exactly SCM Based above advantage design, and is simple in structure, measures accurately.

The technical scheme that the utility model adopted is, a kind of electronic stopclock is characterized in that, comprises single chip control module, and single chip control module is connected with the charactron display module with the keyboard operational module.

Electronic stopclock of the present utility model can carry out simple timing, and is simple to operate, measures accurately intuitive display.

Description of drawings

Fig. 1 is the structural representation of the utility model electronic stopclock.

Among the figure, 1. single chip control module, 2. keyboard operational module, 3. charactron display module.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

As Fig. 1, structure of the present utility model is, comprises single chip control module 1, and single chip control module 1 is connected with keyboard operational module 2, charactron display module 3 respectively.

Principle of work of the present utility model is, keyboard operational module 2 gauge tap,, reset, pick up counting and stop timing, give single chip control module 1 with these information transmission then, single chip control module 1 is carried out timing, and charactron display module 3 comes out time showing simultaneously.

Electronic stopclock of the present utility model can carry out simple timing, and is simple to operate, measures accurately intuitive display.
