Abstract
The invention relates to a technique capable of automatically calgrating timer by utilizing time signal of broadcasting station or TV station prnctually for correcting timing error of timing device. Said technique is characterized by that it uses general AM or FM receiver to receive time signal, after said signal is analyzed and processed, it can contral timer nd make its implement time calibration funtion, Said technoque can be used in any situation having nee of automatically calibrating time. The typical system structure includes three main portions of signal receiving a prodssing unit, control unit an frive unit. Under the action of contral unit the signal receiving and processing unit can be used for searching broadcasting station and making the signal undergo the processes ofr receiving, amplifying demodulation, filter or shaping treatment. The control unit can be used for analyzingand judging time signal and can utilize drive unit interface to calibrate timer at the right moment, and the drive unit can provide the interface of control unit and exterior.
Description
1, technical field
This automatic correcting time technology based on the radio station time signal is used to revise the timing error of time set.
Present technique belongs to electronic technology field.
2, background technology
Time is one of most important notion in people's daily life and the work.Our daily every thing feelings of doing are nearly all relevant with the time, and from three meals in a day, to flight schedule, bank rate is calculated, and all be unable to do without the time.
The mankind go to school a long time ago can the metering time, clocking method along with the progress of society also in continuous development, but up to now, we still rely on the manual method alignment time, the time that people use is still unified inadequately.The manual calibration time also has a big shortcoming, and the confidence level that is exactly the time is poor.If a clock is slow ten minutes, can not discover usually, unless you are just preparing to calibrate it.
In recent years, successively set up the special radio station that sends standard time information in part developed country, by the automatic proof time of the receiving trap of special use.The most long wave bands that use in these radio station, frequency range is 40KHz～100KHz, is 40KHz and 60KHz as Japan, the U.S. and Britain are 60KHz.Accurate when the advantage of this mode is the school, but owing to use long-wave band, signal cover is limited, indoor result of use is relatively poor, and the antenna size of receiving trap is bigger, is difficult for miniaturization, so range of application is very limited.This mode is referred to herein as the pattern of special-purpose time service radio station+receiver.
3, summary of the invention
Broadcasting station or TV station generally all can send time signal on schedule on schedule the time, sort signal has the feature that obviously is different from other signals.At home, time signal is made up of six pulses on schedule, and the first five is the prompt tone of 800Hz, and the 6th is the signal on schedule of 1600Hz, utilizes my door of these features can realize automatic-calibration timer.The timer here refers to that all have the device of clocking capability, as watch and clock movement, and the clock circuit in the computing machine etc.
Use common AM or FM receiver can receive time signal, as present various radios on the market, this technology is very ripe now.For the reliability when improving the school can receive time signal to receiver and carry out analyzing and processing, just such as beginning to receive time signal, during the wrong school that can avoid like this existing in first few minutes on schedule.
We are called the pattern of broadcasting station (or TV station)+receiver this pattern.
4, application
The signal coverage rate of radio broadcasting and TV station is extremely wide, as long as can normally receive broadcasting or the area of TV programme can both use this technology to come the alignment time, with zone time standard irrelevant, thereby have huge market potential and good market outlook.We can say that this will be the once great idea transformation of people's tradition calibration method, have very positive social effect.
5, description of drawings
Accompanying drawing is the system architecture block scheme of a typical embodiments, has shown the process that realizes this scheme.
6, embodiment
This technology based on the radio station time signal can be applicable to the occasion of any automatic alignment time of needs.The exemplary systems structure comprises three major parts: signal processing unit, control module, driver element.The system architecture block scheme is seen Figure of description.
The major function of signal processing unit is to receive wired or wireless broadcasting station, TV station's signal, gives control module after demodulating time signal.This unit generally contains circuit such as signal reception, amplification, demodulation, filtering or shaping.Radio signals has amplitude modulation and mode of frequency regulation, thereby detuner also has corresponding AM demodulator and FM demodulator.Signal processing unit can also be under the control of control module searching broadcasting station automatically.
Control module is the core of total system, and major function is that time signal is carried out analysis and judgement, at suitable moment calibrated timer.Also can contain timer in the control module, it also finishes the function control to other unit in addition, as automatic searching broadcasting station, and manual setting time, time-based warning or prompting etc.
The major function of driver element provides control module and extraneous interface, these external devices can be the displays of liquid crystal (LCD) display, light emitting diode (LED) display and other type, various watch and clock movements, perhaps other contains the circuit or the device of clocking capability, as computing machine, attendance recorder, all kinds of time display screens etc.The type of interface and characteristic depend on these external units.
