Embodiment Construction

[0015] Further illustrate the present invention below in conjunction with accompanying drawing.

[0016] like figure 1 As shown, the method for wirelessly upgrading the taxi meter includes steps:

[0017] (1) The server sends a short message to the taxi equipped with the GSM wireless communication module. The short message contains information such as the current version number, the expected upgrade version number, and the address for downloading the differential package:

[0018] (2) After the wireless communication device receives the short message, it judges whether the short message is legal. If it is legal, it judges whether the current version needs to be upgraded through the version number. A legal SMS contains the correct server IP address, the agreed data header, the correct current pricing version and verification data, etc. Only when these data meet the standards preset in the wireless communication module can it be considered a legal SMS ; For a legitimate short ...

Abstract

The invention provides a method for upgrading a taximeter in a wireless mode, and aims to solve the problems that a large amount of manpower and material resources are consumed, and economic losses are brought to drivers due to queuing when a charging standard of a taxi cab is changed. The method comprises the following steps that: a server transmits upgrading short messages to all taxi cabs; a vehicle-mounted terminal judges whether the version of the vehicle-mounted terminal is the latest version, and the version is upgraded if the version vehicle-mounted terminal is not the latest version; and the vehicle-mounted terminal downloads an upgrading difference packet from the server through a wireless network and verifies whether the difference packet is legal, and the version is upgraded if the difference packet is legal. The invention has the advantages that: a large amount of manpower and material resources which are required to be consumed are saved when the charging standard of the taxi cab is upgraded each time, and the economic losses brought to the taxi cab drivers due to queuing are avoided.

Description

technical field [0001] The invention relates to a data transmission method using a wireless communication network, specifically a method for updating taxi charging standards using a wireless communication network, and a meter involved in the method. Background technique [0002] When taxis in current cities need to change the charging standard, the taxi driver needs to carry the meter to the designated place within the specified time to upgrade the charging standard of the meter. Such a process consumes a large amount of manpower and material resources, and also brings considerable economic losses to drivers due to time-consuming queuing. [0003] With the enhancement of wireless network bandwidth and data transmission capacity, it can accommodate the simultaneous access of thousands or even tens of thousands of links at the same time. This technology provides the possibility to upgrade the meter in a wireless manner, that is, the present invention. Contents of the inventi...
