Abstract

The utility model relates to a swimming pool time clock which comprises a single chip and is characterized in that the single chip is connected with a driving module, an ultraviolet ray receiver and a crystal oscillator, wherein a data signal output by an I/O (input/output) port of the single chip lightens a nixie tube of an LED (light-emitting diode) display module after passing through the driving module, the LED display module is used for displaying the data content output by the single chip, and the power of the single chip and the LED display module are both supplied by a power module. The swimming pool time clock uses an ultraviolet ray remote controller to control the switching over of the timing beginning, the timing stopping, the positive timing and the negative timing, is convenient to use and is particularly suitable for places, such as a natatorium and the like.

Description

The swimming pool timing clock

Technical field

The utility model relates to a kind of swimming pool timing clock.

Background technology

Now a lot of people in the natatorium, swimming pool carries out swimming instruction, the coach generally uses timer such as stopwatch the trainer is carried out chronoscope second, test trainer's speed and the time that is spent; This timer of carrying is because volume is big, hand held in unusual trouble, operation is also inconvenient, often needs two hands, so be necessary to provide a kind of swimming pool timing clock, the swimming pool timing clock of the ultraviolet remote control of particularly a kind of usefulness.

Summary of the invention

In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of swimming pool timing clock easy to use, and this swimming pool timing clock adopts ultraviolet telepilot control, and is easy to use.

To achieve these goals, the technical solution of the utility model is: a kind of swimming pool timing clock, comprise single-chip microcomputer, it is characterized in that: described single-chip microcomputer is connected with driver module, ultraviolet receiver and crystal oscillator, the data-signal of the I/O mouth output of described single-chip microcomputer is lighted the charactron of LED display module behind driver module, described LED display module shows that described single-chip microcomputer and LED display module are powered by power module from the data content of single-chip microcomputer output.

Further, described ultraviolet receiver receives the ultraviolet signal that ultraviolet telepilot emits.

Further, described single-chip microcomputer also is connected with standby power supply module.

Further, described single-chip microcomputer also is connected with the control panel that is used for manually being provided with display data content.

Compared with prior art, the utlity model has following advantage: (1) this swimming pool timing clock adopts LED to show, have the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and steady performance, can clearly illustrate contents such as date, time and week, and this crystal oscillator can guarantee that this swimming pool timing clock timekeeping performance is higher; (2) this swimming pool timing clock also is provided with standby power supply, and when cutting off market electricity, standby power supply is for the single-chip microcomputer operate as normal, and display screen does not show, need not reset contents such as time when last civil power; (3) this swimming pool timing clock adopts ultraviolet telepilot control to pick up counting, stop the switching of timing and reverse countdown and countdown, and easy to use, one hand can be operated, and is specially adapted to places such as natatorium.

Description of drawings

Fig. 1 is the theory diagram of the utility model embodiment.

Embodiment

With reference to figure 1, a kind of swimming pool timing clock, comprise single-chip microcomputer, it is characterized in that: described single-chip microcomputer is connected with driver module, ultraviolet receiver and crystal oscillator, the data-signal of the I/O mouth output of described single-chip microcomputer is lighted the charactron of LED display module behind driver module, described LED display module shows that described single-chip microcomputer and LED display module are powered by power module from the data content of single-chip microcomputer output.

In the present embodiment, the transformer of this power module to AC9V voltage, is the DC12V power supply through overcommutation, filtering circuit with the AC9V voltage transitions with the AC100-200V voltage step-down again, and mu balanced circuit to DV5V, uses the DC12V voltage stabilizing for machine line; In addition, this single-chip microcomputer also is connected with standby power supply module, and when cutting off market electricity, standby power supply is for the single-chip microcomputer operate as normal, and display screen does not show, need not reset contents such as time when last civil power.

In the present embodiment, in order to handle and store the data of bulky complex, it is main control chip that this single-chip microcomputer can adopt the HOLTEK single-chip microcomputer, and dependable performance is superior big with chip storage capacity, can calculate and just score second, falling content such as score second, and showing with LED promptly and accurately; In order to improve the frequency of operation of single-chip microcomputer to greatest extent, can adopt built-in vibration and be 4MHZ its frequency of operation; In order to improve the dutycycle of drive signal on each com port as far as possible, can reduce the quantity that COM drives port, in conjunction with system works frequency at a high speed, the dutycycle that makes drive signal on the com port is 1/8.

In the present embodiment, for limited single-chip processor i/o mouth drives a large amount of LED data pipes, can adopt a plurality of serial ports to change parallel port special IC 74HC595 and come the expansion I/O mouth, as driver module, after pen section that this driver module is sent the single-chip processor i/o mouth and common port signal through and boosting and expand stream, strengthen its driving force, light charactron then; This swimming pool timing clock adopts LED to show, has the brightness height, operating voltage is low, power consumption is little, miniaturization, the life-span is long, shock-resistant and steady performance, can clearly illustrate contents such as date, time and week.

In the present embodiment, this ultraviolet ray receiver receives the ultraviolet signal that ultraviolet telepilot emits, and this ultraviolet ray telepilot picks up counting, stops the switching of timing and reverse countdown and countdown in the 50m inner control.

In the present embodiment, in order to improve the timekeeping performance of this product, this crystal oscillation can be external special use crystal oscillator when walking, and its frequency of operation is 32768Hz, and clock and system clock have separately improved the precision when walking widely in the time of will walking.
