Abstract

The invention discloses a method and device for preventing a taximeter from cheating based on a dynamic change encryption data packet. The method comprises the steps that the taximeter and an automobile sensor generate a first encrypted matching code and a second encrypted matching code at a handshaking stage of the taximeter and the automobile sensor; the automobile sensor generates an encryptedpulse data packet according to the first encrypted matching code, and the taximeter judges whether the encrypted pulse data packet is legal and continuous or not according to the second encrypted matching code to obtain a suspected cheating behavior of the automobile sensor; and the taximeter sends a suspected cheating alarm signal to a data terminal, and the data terminal uploads the suspected cheating alarm signal to a monitoring center through a networking module. According to the method and the device for preventing the taximeter from cheating based on the dynamic change encryption data packet provided by the invention, the difficulty of mileage cheating and cracking of a taxi driver is greatly increased, the operation difficulty of a taxi company is extremely effectively reduced, andthe frontal image of the company is improved.

Description

technical field [0001] The invention relates to a method and a device for preventing cheating of a taximeter based on dynamically changing encrypted data packets, and belongs to the technical field of taximeters. Background technique [0002] At present, the taxi meter is a metering instrument for taxi operators and passenger trade settlement, which is closely related to people's life, so it has attracted wide attention. [0003] According to the current metering regulations, it is required that the taximeter be installed on the taxi, and an independent sensor matching the taximeter must be used, and the signal provided by the vehicle cannot be used directly. The current taxi meter is mainly to install sensors on the taxi transmission or driving wheel, and convert it into a signal that the taxi meter can recognize. [0004] According to the nature of the signal converted by the sensor, the technologies currently used in the market include non-encrypted sensors and static en...
