Description
Technical field
The present invention relates to field of track traffic, relate in particular to a kind of streetlight control box correction device and calibration method.
Technical background
In recent years, along with sustained and rapid development of economy, a large amount of town roads had obtained repairing and is newly-built, as the road lighting lamp of the supporting project of road with every year nearly 20% speed that increases progressively increase fast.
Whenever our street corner of roaming leisurely night, still can find that street lamp is inaccurate on lighting time, disunity has been done conclusion one by one to street lamp inaccurate phenomenon of lighting time, roughly is divided into following four kinds of situations: one side bright not the working in two lamps one side on same light pole both sides; One section of same public lighting circuit is bright, and one section does not work; It is not bright on time that street lamp arrives point; Street lamp bright do not work evening on daytime.
We analyzed lighting time, found each side lighting time disunity of road, and street lamp control appliance time-delay inaccurate when the part clock is seriously walked can reach 1 hour, and this will greatly influence the appearance of the city in city; Because the disunity of lighting time may cause the uneven illumination of street lamp in short-term even, and this has also increased the hidden danger of traffic accident; Daytime, bright lamp was the punctual phenomenon of the most serious bright lamp, not only significant wastage electric energy, caused sizable economic loss, also bring very bad social influence.
In sum, the bright lamp of street lamp can not bring following three shortcomings on time: influence the appearance of the city; Illumination is not up to standard in short-term to cause regional area, increases accident potential; Bright lamp waste on daytime electric energy, social repercussion is big.
Some places have adopted by the technical staff and have inserted the PLC interface to on-the-spot with the PDA write device at present, utilize the skill PDA time, PLC internal time memory cell is refreshed, this method first quarter of verification frequency once is difficult to guarantee the accuracy of streetlight control box time, and the spacious complexity of on-the-spot worker, can cause the system time skew, power failure also can cause the time to produce deviation for a long time, and check-verifying period is long; On the other hand, checking time was as the criterion with the PDA time, be difficult to guarantee that this time is errorless, so reference time was inaccurate.This existing calibration method investment is big, and weak effect is to cause the unpunctual reason of the bright lamp of street lamp, and the unpunctual so numerous drawback that exists of the bright lamp of street lamp is a problem that must solve.
KDZ type streetlight control box is adopted in the area that has at present, the control unit of this control cabinet is the S7-200PLC of SIEMENS, adopt the PPI agreement to carry out control transmission, the main switch of realizing setting-up time every day by this unit, in present system, because this PLC depends on the clock of PLC, so the levels of precision of PLC clock directly had influence on the accuracy of switch lamp time, and the accuracy that how to improve the switch lamp time is that applicant of the present invention is devoted to the problem studying and solve.
