Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
A kind of traffic signals synchronizer comprises clock-signal generator, counter, master controller, clock synchronizer, code translator and signal lamp decoder driver circuit.The input end of the output termination clock synchronizer of described clock-signal generator, the input end of the output termination counter of clock synchronizer, the input end of the first output termination code translator of counter, the input end of the output termination display of code translator; The input end of the second output termination master controller of counter, the input end of the first output termination signal lamp decoder driver circuit of master controller, the control end of the second output termination counter of master controller; The signal lamp corresponding to output terminal control of signal lamp decoder driver circuit opens and closes.
Described clock-signal generator produces the required second signal of counter, and described clock synchronizer is used for the clock on the turnpike road is carried out synchronously.Described code translator is that numeral shows decoder driver circuit, the result of described display display counter.
Principle of work: clock-signal generator produces the required second signal of counter, counter is used for calculating the time that signal lamp of all kinds is lighted, count results is on the one hand by showing by display after the decoder for decoding, on the other hand in order to control the conversion of signal lamp state of all kinds.Clock synchronizer mainly is that the clock on the turnpike road is carried out synchronously, thereby the initial time of clock-signal generator reasonably artificially is set, and realizes that vehicle can keep clear on turnpike road to greatest extent; Master controller utilizes the result of counter, controls on the one hand the order that signal lamp of all kinds is lighted, and on the other hand by driving circuit, the signal lamp main, that Zhi Gandao is corresponding is lighted.Concrete control procedure is as follows:
1, master controller: the crossroad Vehicular behavior only has four kinds of possibilities: major trunk roads are current when 1. beginning, Zhi Gandao no thoroughfare, in this case main green light and a when red, duration is 60s, 2. behind the 60s, no through traffic for major trunk roads, and Zhi Gandao is no thoroughfare still, in this case main amber light and when red, duration is 5s, and 3. behind the 5s clock, no through traffic for major trunk roads, Zhi Gandao allows current, this moment, main red light and a green light were bright, and the duration is 30s, 4. behind the 30s, major trunk roads are not let pass yet, no through traffic for Zhi Gandao, and this moment, main red light and an amber light were bright, and the duration is 5s, get back to the first situation after the 5s clock, so move in circles.Therefore, main controller circuit also has 4 kinds of states, establishes these four kinds of states and is followed successively by S0, S1, S2 and S3.
2, counter: the effect one of counter is to carry out 60s, 30s, and the counting of three kinds of modes of 5s is with control major trunk roads and Zhi Gandao vehicle pass-through time and amber light switching time; The 2nd, send the state switching signal to master controller, master controller carries out the state conversion according to the state switching signal.Counter except the needs pulse per second (PPS) as the clock signal, controlled by the state of master controller.The working condition of counter is: counter begins the 60s counting when master controller gets the hang of S0; Produce return-to-zero pulse behind the 60s, counter is made zero.Counter begins 5s clock counting, sends the state switching signal to master controller simultaneously, the master controller S1 that gets the hang of; Produce again return-to-zero pulse behind the 5s clock, counter is made zero.Counter begins 30s counting, and sends the state switching signal to master controller, the basic counter S2 that gets the hang of; Also produce return-to-zero pulse behind the 20s, counter is made zero.Counter begins again 5s clock counting, and sends the state switching signal to master controller, the master controller S3 that gets the hang of; The same return-to-zero pulse that produces makes zero counter, and sends the state switching signal to master controller behind the 5s clock, and master controller is got back to state S0, the circulation of a beginning new round.
3, signal lamp decoder driver circuit: four kinds of states of master controller are main by the control of signal lamp decoder driver circuit, the light on and off of Zhi Gandao red, yellow, and green lamp.
4, clock synchronizer: make the clock on master, the arterial highway road reach unified, according to the requirement of road, rationally be set its opening time, reduce to greatest extent the congested with cars phenomenon.When vehicle sails into from major trunk roads, as long as advance by the design speed per hour, can block by nothing.Certainly, run into obstacle at a crossing and do not pass through smoothly, as long as the road traffic unification undertaken by this design, then can again can be synchronous at next crossing, thus guarantee to greatest extent unimpededly, realize that road efficiently utilizes.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, therefore all equivalences of being done with the described content of the utility model claim change, all should be included within the utility model claim scope.
