Description

Antenna synchronism timer capable of indicating meteorological condition

The utility model relates to a kind of time set, particularly a kind of time synchronisation device.

Timers such as clock and watch are requisite devices in department such as production, traffic, scientific research and the life, the whether accurate of them all has very big influence to aspects such as work, lives, the effect of clock and watch mainly is by (simultaneously promptly) synchronously between each clock and watch, effect embodies, effect when people pass through clock and watch, could in the moment of arranging and time, finish various action and joint activity, make departments such as each production, traffic, life overlap coordination.In order to solve the stationary problem of each clock and watch, broadcasting station broadcast at set intervals once to the time signal, allow clock and watch proofread frequently, to guarantee the synchronous effect of clock and watch.

At present sophistication and material are greatly improved the accuracy of clock and watch, and day error is less, and accumulated error is also just little, through behind the proof time, they synchronous effect raising has just been arranged.But because most clock and watch can not be done fabulously, and when proof time, can not get very accurate in the school again, so always there are certain error in time that each clock and watch is shown and standard time, more impossiblely make all clock and watch show the identical time at synchronization.

The purpose of this utility model is exactly in order to address the above problem, a kind of wireless synchronization timing device that can show meteorological condition is provided, it can guarantee all timers in an area, all shows the identical time at synchronization, and can also show meteorological condition on timer.

Specific practice of the present utility model is, Time Created the signal transmitting station, launch one group of time encoding pulse signal of representing a certain moment p.s., after timer receives the time encoding pulse, through processing, demonstrate the time by display, coded pulse is according to following principle design, the time signal transmitting station, to launch p.s. one group contain the moon, day, week, the time, minute, second information coded pulse signal.Coded pulse is adopted and is transferred the pulsewidth form, and the wide person of pulse represents " 1 ", and narrow person represents " 0 ".Digital employing binary-coded decimal code (binary-coded decimal), the pulse of expression calendar month needs 5 like this, the pulse of day needs 6, the pulse of expression moon month needs 5, and the pulse of day needs 6, and the pulse in expression week needs 3, pulse during expression needs 6 (demonstration twenty four hours), the pulse that divides needs 7, and the pulse of second needs 7, totally 45.The frequency of pulse is decided to be 128HZ, accounts at interval 8 pulse positions between every group of signal, and transmitting station per second transmission frequency is 120 of the pulses of 128HZ like this.In order to make full use of these pulses, the utility model also can be used to transmit the meteorological state information that people are concerned about at ordinary times.Concrete displaying contents and umber of pulse are allocated as follows: maximum temperature and minimum thermometer demonstration are enclosed and are ± 49 ℃, respectively account for 8 pulses (one of them pulse is represented positive and negative number), each actual temperature constantly represents that scope is ± 49.9 ℃, accounts for 12 pulses (one of them pulse is positive and negative number); Wind direction is divided into 8 directions such as east, the southeast, accounts for 3 pulses, and wind ranges accounts for 5 pulses for the 0-12 level, and each needs 8 pulses actual wind direction wind-force and forecast wind direction wind-force; The meter per second for 0-50 is enclosed in the anemometer demonstration, accounts for 7 pulses; Weather conditions have fine, and 14 kinds of situations such as partly cloudy, cloudy, cloudy, light rain, moderate rain, shower, thunderstorm, heavy rain, heavy rain, mist, slight snow, moderate snow, heavy snow account for 5 pulses, and each needs 5 pulses present situation weather conditions and forecast weather conditions; Relative humidity is represented percentage with 8 pulses; Atmospheric pressure represents to account for 13 pulses with hundred handkerchiefs.Weather information will account for 82 pulses, adds up to temporal information to account for 127 pulses altogether.Consider except the time, minute, second information must per second all sends once, the then unnecessary per second of all the other information sends, so the moon, day, week and weather information can be divided into four groups of circulation transmissions in turn.First group is calendar month, day, moon month, day and week; Second group is present situation and forecast weather conditions and atmospheric pressure, relative humidity; The 3rd group is maximum temperature, actual temperature and minimum temperature; The 4th group is actual wind direction wind-force, forecast wind direction wind-force, actual wind speed, so only needs 34 pulse positions just above-mentioned information rotation can be sent.To transmit and receive synchronously in order making, also will to add two state pulses in addition, first group of information of " 00 " expression emission; Second group of " 01 " expression emission; The 3rd group of " 10 " expression emission, the 4th group of " 11 " expression emission.Transmitting station per second transmit signal pulse order is as follows: 63 of extra-pulses, 34 of 2 of state pulses, calendar and meteorological pulses; The time, 20 of minute, second pulses, 1 of basic pulse, totally 120.Extra-pulse is no information pulse, with the emission of " 0 " form, keeps and launches other information uses (for example can be used to launch special economic information etc.) from now on.In order to prevent the width pulse, require last pulse signal whenever per second transmits equally, also to launch with " 0 " state so established a reference signal to the receiver influence of demonstration time.

Technical solution of the present utility model is, it is made up of radiating portion and receiving unit, radiating portion is by high-precision crystal oscillator, frequency divider, narrow pulse converter, counter, registers group, four select an analog switch, incorporate to go here and there out shift register modulating oscillator into, modulator, power amplifier and emitting antenna are formed, receiving unit is by receiving antenna, tunable receiver, detuner, amplification shaping device, integrating circuit, voltage identificating circuit, monostable circuit, SI PO shift register, four select a switch, latch, decoding, driver and charactron display are formed.
