Price meter parameter adjusting method and system based on multi-encryption mode

Abstract

The invention discloses a price meter parameter adjusting method and system based on a multi-encryption mode, which comprises the following steps of: collecting local parameter information by the price meter and requesting the server after being coded by a first encryption and decryption module; decrypting , by the price meter, the data returned by the server and verifying whether the parameter needs to be downloaded; downloading a token and other local information by using a second encryption module if the parameter needs to be downloaded, carrying out data encryption, and carrying out data request to a download address; decrypting the downloaded data and storing the data if the decrypted data is valid. The method can adjust the parameter of the price meter reader in a wireless mode, thereby achieving the purpose of safe and reliable remote price adjusting. The cheat of the server end and the local data is prevented, and the validity and accuracy of the adjustment are ensured.

Description

technical field [0001] The invention relates to a method and system for adjusting remote parameters of equipment, in particular to a method and system for adjusting remote parameters of price counters. Background technique [0002] With the continuous development of the current economy, people's travel is more dependent on taxis, which makes the taxi industry develop rapidly. Existing taximeters can realize simple pricing processing. Taximeters are a kind of measuring instrument, which are used to measure the rental duration and measure the mileage according to the signal transmitted by the mileage sensor, and use the measured timing time and mileage as Basis, calculates and displays the fare payable by the passenger taxi. [0003] However, whenever the meter needs to update data, for example, when the billing strategy needs to be updated, the measure to be taken is to manually input the new billing strategy into the meter to achieve the corresponding data update, which is ...
