Passenger car energy consumption data acquisition device and control method using can bus

Abstract

Provided is a coach energy consumption data collection device adopting a CAN bus. The coach energy consumption data collection device comprises a power supply voltage stabilizing unit, an intelligent unit, a system reset unit, a data storage unit, a debugging interface, a display unit, an acceleration detection unit, a CAN interface unit, a communication interface level conversion unit, a coach load signal unit, a wireless communication module and a PC RS-232 interface. The intelligent unit detects a load of a coach and a three-axis acceleration signal, and the three-axis inclination angle is calculated through three-axis acceleration data; data of the speed of the coach, the consumed fuel quantity, the fuel consumption rate and the like are read through the CAN interface unit, collected data is analyzed and processed according to an algorithm designed by software, and the real-time effective fuel consumption rate is obtained; meanwhile, data meeting the standard test condition is screened out, and related data is displayed through the display unit. The coach energy consumption data collection device has the advantages that coach energy consumption related data can be collected rapidly in real time and transmitted to a data processing center, full-automatic coach energy consumption data analyzing, processing and assessing can be achieved conveniently, and the work efficiency and data accuracy are improved.

Description

technical field [0001] The invention relates to an energy consumption data collection device, in particular to a bus energy consumption data collection device using a CAN bus, and belongs to the technical field of energy consumption data collection. Background technique [0002] Energy conservation monitoring is an important means for the government to promote the rational use of energy. The "Energy Conservation Law of the People's Republic of China" clearly stipulates that the relevant transportation departments of the State Council shall be responsible for the supervision and management of energy conservation in the relevant fields of transportation across the country in accordance with their respective responsibilities, and formulate the fuel consumption limit standards for vehicles and ships in transportation operations, which do not meet the standards shall not be used for operation. According to the relevant national standards, all localities should strengthen the det...

Problems solved by technology

This kind of intelligent operation system can promote energy saving and emission reduction to a certain extent, but because there is generally no detection of the load of passenger cars, and no detection of the flatness and straightness of the road surface, it is different from the transportation industry standard "Fuel Consumption of Operating Passenger Cars" Limits and Measurement Methods" are far apart, and cannot be compared with the specified fuel consumption limits, and it is impossible to determine whether the energy consumption of passenger cars meets the standards under non-professional test conditions
