Embodiment two
The Ben Fa system comprises several street lamps, and each street lamp all is equipped with gps synchrotimer, wireless transceiver, transducer, carries out second synchronously with the gps satellite system, will the time cycle be decided to be 1s.And be divided into 10 five equilibriums, be respectively 0s, 0.1s, 0.2s, 0.3s, 0.4s, 0.5s, 0.6s, 0.7s, 0.8s, 0.9s.Regulation 0s is the initial signal point, and 0.1s-0.5s is a signal transfer point, and 0.6s is for transmitting end point, and 0.7s is for turning on light signaling point, and 0.8s is for turning off the light signaling point, and 0.9s is used for fault and reports, and the regulation forwarding algorithm is sequential algorithm, and forwarding in same second.Initial signal point emission 0x55, forward signal point emission 0xAA, the signal 0x01 that turns on light closes modulating signal 0x02.Street lamp is after detecting personnel's vehicle arbitrarily; To send signal 0x55 constantly at 0s, other lamps after receiving 0x55 or 0xAA signal, blast lamp separately; And press the moment point forward signal 0xAA of forwarding algorithm in regulation, weaken the brightness of lamp separately after the certain time-delay automatically.The street lamp that receives signal 0x01 or 0x02 will be transmitted in identical moment of next second this signal, and switch lamp on request.
The switch of street lamp is controlled in this road lamp system control service time and remote control, and system's timing setting lighting time is 7 points early, the point in evenings 7 time of turning off the light.And combined with remote-control, according to according to circumstances using guidance command remote control street lamp by remote control center season.As in winter in spring; Turn on light too late at 7 in evening, just send the order 0x01 that turns on light in control centre, receive the lamp of 0x01 order and will turn on lamp separately 6 of evenings; And transmit a subcommand 0x01 at a following second synchronization; Other street lamps of receiving 0x01 will also be turned on lamp separately, and transmit a subcommand 0x01 at a following second synchronization, so just can open whole street lamps.Turn off the light a bit evening in 7 of mornings summer and autumn; Just more early 6 send out the order 0x02 that turns off the light by control centre; Receive the lamp of order 0x02 and will close lamp separately, and at following second synchronization forward command 0x02 once, other street lamps of receiving 0x02 will also cut out lamp separately; And transmit a subcommand 0x02 at a following second synchronization, reach the effect of closing whole street lamps.Do not receive order just by the setting-up time switch lamp.Use regularly like this to combine with remote control, can control street lamp easily, the realization lighting energy saving is neglected neither, and also can realize the random control of street lamp at special weather.
This street lamp combines the gps time dissemination system, is unified in 12:00 entering at night power save mode, light is dropped to 50% brightness.Simultaneously combined sensor 0s that is defined in according to agreement after detecting personnel's vehicle sends the blast signal, and the street lamp of receiving signal is according to the rules at the moment forward command of regulation, and turns on light or blast, realizes that car comes lamp to open, and car is walked the dark effect of lamp.
Forwarding process: 0s receives the street lamp of signal 0x55, will be at 0.1s, 0.2s, 0.3s, 0.4s, five moment point of 0.5s 0xAA that transmits, and the lamp separately of blast simultaneously.
0.1s receive the street lamp of signal 0xAA, will be at 0.2s, 0.3s, 0.4s, four moment point of 0.5s 0xAA that transmits, the lamp separately of blast simultaneously.
0.2s receive the street lamp of signal 0xAA, will be at 0.3s, 0.4s, three moment point of 0.5s 0xAA that transmits, the lamp separately of blast simultaneously.
0.3s receive the street lamp of signal 0xAA, will be at 0.4s, two moment point of 0.5s 0xAA that transmits, the lamp separately of blast simultaneously.
0.4s receive the street lamp of signal 0xAA, will be at moment point of 0.5s 0xAA that transmits, the lamp separately of blast simultaneously.
0.5s receive the street lamp of signal 0xAA,, do not transmit with blast lamp separately.
If street lamp breaks down, will report 0xOf at 0.9s, just receiving terminal is received DTC after going near the street lamp, will know that street lamp breaks down, also can increase fault receiving platform and control centre simultaneously and network.
In sum, intelligent road-lamp wireless control system and method that the present invention proposes through the transmission range that forward relay has extended signal widely, can improve the coverage of the signal of system.
The present invention is improved to multimachine with an existing machine single emission and repeatedly launches, and the stability of system is improved widely, and antijamming capability strengthens greatly.
Signal is realized the wide area time synchronized via satellite, solves the characteristic that blazons of street lamp.Combine simultaneously to realize the different commands function with different moment point, the signal that all unit of system are sent in same point is identical, can noisyly not produce, and improves the stability of system greatly, emission according to the rules, communication effectively and accurately.
Here description of the invention and application is illustrative, is not to want with scope restriction of the present invention in the above-described embodiments.Here the distortion of the embodiment that is disclosed and change are possible, and the replacement of embodiment is known with the various parts of equivalence for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present invention or substantive characteristics, and the present invention can be with other form, structure, layout, ratio, and realize with other assembly, material and parts.Under the situation that does not break away from the scope of the invention and spirit, can carry out other distortion and change here to the embodiment that is disclosed.
