Problems solved by technology
[0005] However, there is a problem in the above two methods of the prior art: the above methods are all based on the unique identification of the vehicle for tracking, which will leak the behavior privacy of the vehicle user
Some users or social groups do not allow or do not want the traffic statistics system to disclose their behavior privacy. For example, they do not want to disclose that they have arrived at A and B at a certain time today. However, the identification of vehicles in the prior art is With the license plate or the unique identification of the vehicle, it is obviously unable to protect the privacy of the vehicle user

Embodiment Construction
[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0030] In order to supervise and control the traffic system more effectively, it is very necessary to collect traffic statistical information, but after analyzing the measurement requirements of various traffic information, the inventor found that it is not necessary to obtain and record the whereabouts of each vehicle For example, what we need to obtain is that a certain vehicle passes through A at time t1 and B at time t2. The specific vehicle can be completely ignored, that is to say, it is completely unnecessary to read the unique vehicle The method of randomizing the RFID identification of the vehicle ensures that the traffic behavior of the vehicle can be obtained without leaking the vehicle information.
[0031] Therefore, the method provided by t...

The invention discloses a method and a radio frequency identification label for acquiring traffic information. The method comprises the following steps of: transmitting the stored random code to a reading device when the radio frequency identification label arranged on a vehicle receives a reading request signal transmitted by the reading device, or transmitting the stored random code according to the preset period; and judging whether the preset random code generation condition is met, if so, generating a random code and updating the stored random code by using the generated random code, otherwise, ending the flow. According to the characteristics of traffic information statistics, the invention adopts a mode of randomizing the radio frequency identification label of the vehicle instead of reading a unique identifier of the vehicle, and protects the privacy of a user of the vehicle in the process of traffic information statistics. Therefore, the traffic information statistics can be accepted by the user of the vehicle easily.
Description
technical field [0001] The invention relates to the technical field of information acquisition, in particular to a method for acquiring traffic information and a radio frequency identification tag. Background technique [0002] In order to collect traffic statistics of traffic flow, the most common way is to identify each vehicle and track its traffic behavior, and infer large-scale traffic information from the traffic behavior of each vehicle. [0003] One of the commonly used methods at present is to extract the unique identification of each vehicle in the traffic system, such as the license plate, so as to facilitate the tracking of the vehicle. This method does not need to install additional hardware devices on the vehicle, but it will be affected by light quality, air quality In addition, character recognition technology can also be used, for example, using infrared devices for optical character recognition, but this method requires complex algorithms, and the existing ...
