Abstract
A timing and numbering device comprises a singlechip composed of a memorizer for storing the accumulative value of working times and working hours and a reference time generation module for providing the unit-time reference value of working hour accumulative total, a signal input module for representing the signals which are converted from the signals of monitored equipment in working conditions for being able to identified by the singlechip, and a power supply module for converting the extraneously-provided power supply into stable low-voltage direct current so as to supply electricity for two-in-one motor timing and numbering device, and the singlechip adds up the working time and working hours of the monitored equipment according to the signals inputted by the signal input module. The timing and numbering device applies singlechip technology to upgrade and integrate traditional timer and counter, and the mechanical parts are deleted, so the life time thereof is greatly enhanced because of non-abrasion, meanwhile, the volume is small and the weight is light because the timing and numbering functions are integrated in one, further, due to no use of battery, the maintenance is convenient, without the hidden danger of battery liquid leakage.
Description
Technical field
The utility model relates to a kind of low voltage component, especially a kind of timing, counter.
Background technology
The timer sum counter is common low voltage component, and the principle of work of traditional timer sum counter is similar to clock and watch, adopts mechanical gear to realize function.Present widely used so-called electronic timer only is to have added the electronic circuit that is called " quartz oscillator " in time-base generator (second signal) part, and other parts remain based on mechanical gear (being similar to crystal clock).The similar above-mentioned mechanical type timepiece or the shortcoming of counter are: complex structure, low precision, exist mechanical wear, life-span short.
The pure electronic type timing counter that has liquid crystal display is also arranged at present on the market, what use is and liquid crystal display electron clock and watch similar techniques, its major defect is to need to use powered battery, need to change battery in the use, this makes it be not suitable for being applied to long-term unattended equipment, and has the hidden danger of damaging circuit because of battery leakage.
The utility model content
The purpose of this utility model is to provide a kind of precision height, life-span length, does not need to use powered battery, collection timing and tally function timing, the counter as one.
For achieving the above object, the technical scheme that the utility model adopted is:
A kind of timing, counter, it comprises single-chip microcomputer; Signal input module, signal input module will be used to represent the signal that the conversion of signals of monitored equipment duty becomes single-chip microcomputer to discern; Power module, the power source conversion that is used for that the external world is provided are stable low-voltage DC and are two-in-one timing, technology device circuit supply; Single-chip microcomputer is according to the work number of times and the working time of the signal accumulative total monitored equipment of signal input module input, and single-chip microcomputer comprises the storer that is used to store work number of times and working time aggregate-value, be used to provide module takes place reference time of the unit interval reference value of working time accumulative total.
Because the employing of technique scheme, the utility model compared with prior art has the following advantages:
The utility model utilization singlechip technology is upgraded to traditional timing, counter and is integrated, has cancelled mechanical part, because of there not being the machinery wearing and tearing, is improved its serviceable life greatly; Simultaneously, be one with timing, tally function and two, volume is little, in light weight; Owing to do not use battery, be more convenient for safeguarding, and do not have battery leakage hidden danger.
