Description
One, technical field:
The utility model is a kind of automatic record bus method and device of patronage up and down, writes down method and the device of bus in the volume of the flow of passengers of each website and day part especially automatically.
Two, background technology:
Along with the acceleration of urbanization process, the raising of people's living standard, urban population and vehicle, particularly private car quantity sharply increases, and the traffic congestion phenomenon is very serious, and urban transport problems becomes increasingly conspicuous.Therefore, many knowledgeable people do one's utmost to advocate and greatly develop city bus, alleviate the traffic pressure in city, reduce municipal pollution.
But how to carry out the planning of the public transport of science, how to arrange public bus network, the passenger flow distributed data is the basis.Existing bus passenger flow quantitative statistics mainly contains three kinds of methods, the number that first driver or ticket seller get on or off the bus with the knob counters count; It two is to receive cash by checking, and calculates number of passengers by cash quantity; It three is to utilize the quantity that dissimilar holders get on the bus on the different websites on the different websites of bus IC card system statistics, uses the cash quantity of being received to calculate the number of passengers of inserting coins again.
Method one is a kind of interim, but count statistical method more accurately, yet this manual method workload is big, the cost height, be difficult to lasting use, method two just can be calculated one day non-total patronage of holding the public transport monthly ticket of a regular bus, can not get each platform number of getting on or off the bus and the number of holding the public transport monthly ticket, method three can be calculated the quantity of different IC cardholder on the non-total patronage of holding bus IC card of one day regular bus and each website, can not get the quantity of the passenger loading of inserting coins on each website, also can not get the number that each website is got on or off the bus.
Three, summary of the invention:

(3) technique effect
Advantage of the present utility model is to realize public transit vehicle get on or off the bus number and automatic record, data accumulation by the long period, obtain the time dependent passenger's distribution situation of each website data in city, for Urban Traffic Planning provides the accurate localization of an aspect, the passenger flow data of timing.
The utility model adopts pyroscan as the counting acquisition sensor, and the infrared ray that has necessarily around the circle direction with a kind of is installed on the doorframe of getting on or off the bus of bus, and is connected on everywhere the signal processor.When passenger getting on/off passes through coil, the infrared coil of human body will cause the variation of magnetic flux in the coil, and then cause the variation of electromotive force in the coil, this variation is through signal processor, signal place device will detect the variation of signal, the output result of the signal processor of the corresponding this positive and negative variation of storage of processor record.If passenger getting on/off is represented in the variation with signal, by counting accumulative total, just can obtain the number that each website is got on or off the bus so.
When on bus, having installed public transport IC card reader, then the storage of processor with storer and signal Processing Lu the eleventh of the twelve Earthly Branches bus IC card card reader unites two into one, or carry out integrated between the two, storage of processor is got on or off the bus in the total number of persons obtaining each website, also can obtain the number that different holders get on the bus on each website respectively, and the people's that inserts coins number.
