Receiver mainly is made up of integrated electric piece PT2272 of antenna, superregenerative receiver, wave filter, amplifier and wireless remote control etc.NPN triode and peripheral circuit constitute superregenerative receiver among the figure, and it receives radiofrequency signal from transmitter by antenna, delivers to the wave filter of being made up of operational amplifier after the detection.Signal amplifies 14 pin of delivering to PT2272 through filtering.PT2272 is the wireless remote control integrated circuit supporting with PT2262.Its 10-13 pin is data output end, its output be 8421 coded signals that recovered, it can be received by single-chip microcomputer.17 pin of PT2272 are UT signals, and when it was high voltage, the expression data were effective, and coded signal can effectively be received by single-chip microcomputer.The 1-9 pin of PT2272 is the geocoding wire jumper, when having only PT2262 take-up with corresponding transmitter identical, receives just effectively, otherwise invalid.
The course of work of these solar energy radio traffic lights is as follows:
The traffic signal control 1 of host A produces the phase lamp chrominance signal of road junction all directions on a time period according to the program that sets in advance, and the parameter of each phase place can be adjusted and preserve.This light color signal is when delivering to the signal lamp group 5 of host A, by two-way serial ports the light color coding is sent to reception emission charge controller 2, and extension set that reception emission charge controller 2 transmits or the status signal of this machine, by the program that sets in advance, change the phase lamp chrominance signal of control road junction all directions.
After reception emission charge controller 2 received the light color coded signal of traffic signal control 1, control controller signals transmitter 4 usefulness radio wave transmission were to each extension set B.It is subjected to the control survey solar cell 6 of traffic signal control 1 serial ports, the voltage of accumulator 7, to accumulator 7 chargings; Control signal lamp duty echo receiver 3, controller signals transmitter 4; The signal lamp group 5 of driving host A; It also gives traffic signal control 1 duty of host A and extension set B by serial ports.
Whether normally signal lamp duty echo receiver 3 receives the next extension set B duty of extension set B emission information, and information is delivered to traffic signal control 1.
Controller signals transmitter 4 according to the command information of traffic signal control 1, coded signal takes place and by transmitter with radio wave transmission to each extension set B.
The radiowave that the light color signal receiver 8 of extension set B receives from controller signals transmitter 4, and after decoding, deliver to signal lamp duty control detection device 9.
Extension set B signal lamp duty control detection device 9 finishes solar cell 6 and accumulator 7 voltages of measuring extension set B, receive that light color coding, control signal lamp duty transmitter 10, extension set accumulator 7 from light color signal receiver 8 charges and function such as signal lamp group 5 work.After signal lamp group 5 was received the control signal separately that the single-chip microcomputer of signal lamp duty control detection device 9 delivers to, the signal lamp group 5 of host A and each extension set B showed light color separately simultaneously.Because the code switch setting of each extension set B has nothing in common with each other, therefore, the light color of each extension set B is also inequality.Circulation emission in per 0.5 second receives once, so light color constantly changes by rule.When each phase loop once after; coded command is checked in one of host A emission; after extension set B receives and checks coded command; check separately duty and accumulator 7 voltages; adjudicate whether normally separately, send normal separately or abnormal coding radiowave according to the state timesharing of geocoding switch then.After host A receives the signal of extension set B,, then send signal lamp group 5 to out of repair extension set B at once and transmit the yellow signal that dodges if there is one or more extension sets B undesired.Whether host A is normal with radiowave inquiry extension set B every certain cycle, and extension set B answers host A by the value timesharing of code switch with radiowave automatically; When some extension set B break down, comprise that the work of host A, extension set B can not produce inharmonious when battery was not enough, can guarantee traffic lights normal indication, correctly direct traffic.When signal lamp group 5 yellow sudden strain of a muscles, every some seconds, be generally and send one second again to hundreds of in tens seconds and check coded command, when each extension set B recovers just often, for example through after 7 chargings of 6 pairs of accumulators of solar cell, after accumulator 7 voltages recover normally, host A will receive normal coding and answer, and host A will be got back to original normal procedure operation.Extension set B sends the coding radiowave according to the code switch timesharing, can avoid each extension set B to launch the disadvantage that host A can't receive simultaneously.If extension set B signal lamp duty control detection device 9 can not receive any coding of light color signal receiver 8, it can be automatically converted to the yellow duty of dodging under the control of single-chip microcomputer, reaches the function of automatic function degradation.
Signal lamp duty transmitter 10 is controlled by signal lamp duty control detection device 9, and whether normal information is by the signal lamp duty echo receiver 3 of coded system emitting radio wave to host A the duty of extension set B.
Owing to the AD transducer is arranged respectively at reception emission charge controller 2 and extension set signal lamp duty control detection device 9, can measure solar cell 6 voltages of main frame or extension set separately, when solar cell 6 voltages were lower than certain value, the expression ambient light illumination was very dark.Reception this moment emission charge controller 2 and extension set signal lamp duty control detection device 9 are used under the control of single-chip microcomputer has the pulse of certain dutycycle to go drive signal lamp group 5.Because pulsed frequency is than higher, in the scope of hundreds of hertz to several KHz, human eye can not perceiveed flicker, but signal lamp group 5 is worked in the power saving mode, and accumulator 7 can be saved electric energy over half, the working time when prolonging no sunlight greatly.
Fig. 9 is seen in installation when this solar energy radio traffic lights use in the standard crossroad.Three extension set B of a host A control, a host A or extension set B are installed in each crossing.
