Utilize the satellite time signal to realize that the principle of solar energy spike synchronous working is:
The satellite positioning device that can receive within the border in China all provides the ability that the location coordinate is discerned, and accurate time service function.If when using the time service function of gps system, we can obtain the time service precision of about 100ns at present.For the synchronous railway spike of sun power, common 16 hours cumulative errors should be unable to exert an influence to the work of the synchronous railway spike of sun power less than flicker cycle 5%, and 16 hours is to set with each work maximum duration of the synchronous railway spike of sun power.With per minute 60 times flicker, per second has a flicker cycle, and by dutycycle design in 1: 1, then each flicker is bright 500ms, the 500ms that goes out, in actual motion, error less than 5% just less than 25ms.
Satellite positioning module can provide the date Hour Minute Second equal time data of coordinate information, Greenwich Mean Time, and synchronous second signal, and wherein the error of second signal is looked the configuration difference of chipset and module usually less than 100ns synchronously, and these data can be variant.After the satellite receiver module operate as normal, after promptly receiving satellite-signal and effective identification, can provide coordinate data, time data and second synchronizing signal, and not receive satellite-signal or the satellite-signal received can not discern the time, the satellite receiver module does not have above-mentioned data and signal output.The present invention with second synchronizing signal as counter enabling signal source, the meter reading precision is decided on actual request for utilization.After microprocessor identifies second synchronizing signal, beginning was counted according to the predetermined cycle, if use 1ms as the count cycle, then can obtain the count number of a 1000ms between the synchronizing signal two seconds, in this count number, can obtain any synchronous work period greater than 1ms, then another synchronous cycle has begun again 1000ms later on, so, for discrete solar energy spike, can also can be extended to several seconds synchronous signal cycle the count cycle according to designing application demand the lock in time that is obtained.Present embodiment, if the flicker frequency of railway spike is 60 times/minute, then counter is set to control signal of every 500ms output, light when synchronizing signal begins synchronously with second, continue to extinguish behind the 500ms, light when receiving second synchronizing signal more next time again, go round and begin again, the synchronous railway spike of sun power is closed when daytime.Different flicker frequencies only need be set lighting later working time and dutycycle, when for example the flicker frequency of the synchronous railway spike of sun power is set to 240 times, dutycycle 1: 1, this moment is when beginning when a second synchronizing signal, LED is the 125ms on and off at interval, begin next cycle when next second synchronizing signal arrives again.Different flicker frequencies all can obtain in different time configurations with different dutycycles, when cycle of working time during greater than 1 second, in order to obtain synchronously, need identification odd number second or even number second, as long as the Hour Minute Second signal that at this moment calls in Greenwich Mean Time is discerned.The discrete synchronous railway spike of installing of sun power will be under unified configuration lock in time synchronous working, be not subjected to the distance limit of installation site, the work synchronism between each railway spike is very good.
The housing of the synchronous railway spike of embodiment sun power adopts pressure-bearing and is fit to the profile that road traffic uses, and inner space with mounting circuit boards and battery pack V1, and the outside has the position that solar panel VS is installed.The housing of the synchronous railway spike of sun power is satisfying under the prerequisite of above-mentioned condition, can use multiple shape profiles such as circle, square, ellipse.Use square aluminum mass shell body among the embodiment, adopt 125 * 125 * 25 millimeters Al-alloy casings that meet GB/T 19813-2005 standard-required.Housing does not influence the final result of use of the synchronous railway spike of sun power.
Solar cell VS can use all types solar cell of photoelectric transformation efficiency greater than solar energy spike power demand area ratio, used polysilicon solar cell in an embodiment, adopt the polysilicon solar cell of one group of about 0.55W, solar cell VS is installed on the solar panel installation site on housing top, and covers on the solar cell with wear-resisting acrylic transparent film.The configuration of solar cell VS need be considered the power consumption requirement that circuit is formed, and makes the number at sunshine of land used, and the technical goal of railway spike etc., select adaptive; The capacity of solar cell VS does not have direct relation with realizing the target of synchronousing working, and the continuous working period of the synchronous railway spike of sun power is relevant with solar panel VS and accumulator V1 capacity.
Battery pack V1 adopts the built-in miniature battery pack, the built-in miniature battery pack can be used and meet the battery pack that the road traffic environment temperature variation required and satisfied built-in volume requirement and capacity requirement, used Ni-MH battery in an embodiment, adopt the Ni-MH battery of two joint AAA type 800mA/H capacity, the inner space of the housing of present embodiment only can hold two joint AAA batteries, and uses two joint AAA nickel-hydrogen accumulators to meet the operating voltage requirement of railway spike chipset and module.In actual use, difference with environment for use, a configurable joint, two joint or multiple batteries more, the battery of also configurable other capacity or material, its cell arrangement pattern mainly is limited by the parameters such as adaptation coefficients of the voltage that uses chipset or module, power, solar panel VS, and the effect of synchronousing working with railway spike does not have necessary relation.
Discharge and recharge and open and close in the control circuit charge-discharge control circuit DA and mainly be responsible for battery pack V1 is discharged and recharged control, prevent to overcharge or overdischarge; Keying control circuit L1 is responsible for detecting the work threshold value of solar energy spike, will close solar energy spike by day, opens solar energy spike night, accepts microprocessor CU control simultaneously, to realize the working state administration to each parts.
Satellite receiver module CT can receive the satellite time signal, can select the receiver module that uses single-chip or multicore sheet to form.The satellite time service source of selecting when satellite receiver module CT and solar energy spike are implemented synchro control is complementary, can select the receiver module of GPS System in USA, or the receiver module of Europe " Galileo " satellite, or the receiver module of Russia's " GLONASS " global navigation and position, or China's " Big Dipper " satnav receiver module, different satellite receiver modules is similar on final result of use.Satellite receiver module CT uses supporting with it micro-satellite receiving antenna TX, so that can obtain best reception and meet technology and the volume requirement that is installed in the solar energy spike.The selection of satellite receiver module CT, though but the satellite time service source that commercialization is at present used has at least four kinds, but use the GPS of USA system that remains comparatively widely in the world, and its chipset is also comparatively ripe and cheap, present embodiment uses gps system as synchronous time dissemination system source, adopts U.S. SiRF chipset as the satellite receiving chip.Usually chipset is formed have in actual use and used the module that stresses so that finally use, the actual most important applications of present embodiment is time service, adopt that Hangzhou Command Communication Equipment Co., Ltd produces based on the miniature low-power consumption module of CTCT type of U.S. SiRFIII GPS chipset as satellite receiver module CT.This module is mainly used in the industrial application that needs synchronous time service, also exports data such as Greenwich Mean Time and coordinate simultaneously, has second synchronizing signal output, the synchronous signal impulse width-adjustable, and the time precision error that is as the criterion with rising edge is smaller or equal to 15ns.
Microprocessor CU mainly finishes the signal that satellite receiver module CT is received and carries out post-processed and final output efficient synchronization control signal, microprocessor CU and satellite receiver module CT coupling, microprocessor CT realizes the synchronous working pattern of solar energy spike by programmed control.The tape program control of confession and the microprocessor of processing power are arranged in the market, under the prerequisite that satisfies power consumption/processing power/requirements such as control function/volume, almost all can adopt.The 51 Series P 89LPC915HDH type single-chip microcomputers that the microprocessor CU of present embodiment uses the tape program of ripe low-power consumption to handle, select the reason of this microprocessor to be based on it and have function and can satisfy request for utilization, and power consumption and voltage indexes also meet request for utilization.Microprocessor CU opens and closes control circuit L1 by instruction control and realizes work management to satellite receiver module CT, and when microprocessor CU was in " automatically " state, satellite receiver module CT directly obtained power supply by DC/DC circuit L2; When microprocessor CU intervenes satellite receiver module CT duty, can be by opening and closing the working power of control circuit L1 cut-out satellite receiver module CT.
Electroluminescence device can adopt LED or other electroluminescent element, and present embodiment adopts LED, and microprocessor CU is connected with led circuit.The microprocessor of not all model is driving LED directly, when needs are two-sided when lighting the LED of solar energy spike, can increase Drive and Control Circuit QD at the led circuit front end, QD is connected to led circuit by Drive and Control Circuit, driving circuit QD amplifies drive current, and driving circuit QD uses common low-power transistor to get final product; When using single face to show, P89LPC915HDH type single-chip microcomputer can directly drive required LED.The color of LED selects to look the actual needs setting, general redness, the yellow and white LED of adopting, usually the single face display window of solar energy spike is installed 3 LED, if the double-sided display window is then respectively installed 3 LED, its brightness and half strong angle should meet national standard.
The synchronous railway spike of sun power by day, to quit work when for example illumination is greater than 150LEX, when entering night, solar cell VS electromotive force is lower than closes threshold value, open and close control circuit L1 and be unlocked this moment, microprocessor CU is activated, satellite receiver module CT starts, begin to enter cold start, not output of the serial port of satellite receiver module CT and second signal output part in searching the star process, after receiver module CT receives effective satellite-signal, will will export Greenwich Mean Time and coordinate parameters from serial port simultaneously from signal Synchronization end each a second output second signal second.In the present invention, coordinate data be will abandon, real-time time data and second signal only used.Second, the pulse width of signal output can be provided with, and in receiver module CT, present embodiment has been selected signal pulse width second of 100ns, and the rising edge of signal pulse is the sign that begins of second synchronizing signal with second, and its positive negative error is less than 15ns.Microprocessor CU interrupts capturing and produced hardware interrupts after the synchronizing signal in effective second, and beginning is unit count with 1 millisecond, digit can decide on final output accuracy requirement, and step-length also can be decided as required, as long as final precision satisfies request for utilization.Since the moment that second, synchronizing signal arrived, the control signal of LED is lighted in microprocessor CU output, when predetermined ignition period finishes, the control signal of LED is closed in output, open counting again and light LED when next second synchronizing signal arrives, LED is lighted, closes in circulation, finishes until the work period, be illumination during greater than the system closing threshold value, the synchronous railway spike of whole sun power will be closed.If when using 60 flicker frequencies, when second, synchronizing signal arrived, light LED, when counting is expired 500ms, close LED, when next second synchronizing signal arrives, begin second control cycle again, until closing.
Because the control interval is very little, the clock accuracy of microprocessor satisfies the operating error requirement of the synchronous railway spike of sun power fully, so generally do not need the flow process that calibrates for error.Under the condition of time synchronized,, can realize the synchronous working state of multiple different control models by the control of software.For example, when special festivals or holidays or special application demand, need regularly start solar energy spike, its implementation method is the time conditions that startup is set in the program of microprocessor CU, use Greenwich Mean Time to carry out local zone time conversion and calibration according to the coordinate time zone again, control the opening and closing time of solar energy spike by local zone time, the time conditions that opening and closing time promptly need be provided with, microprocessor CU controls the duty of solar energy spike by the comparison time condition, when satisfying entry condition, then open, satisfy and then close solar energy spike when closing condition.
Above embodiment has done comparatively detailed description to solar energy spike synchronization control method of the present invention; but these descriptions are not in order to limit protection scope of the present invention; any technician who is familiar with this technology; change and the retouching done in not breaking away from design of the present invention and scope all should belong to protection scope of the present invention.
