Vehicle-mounted terminal for measuring vehicle load and measuring and computing method

Abstract

The invention discloses a vehicle-mounted terminal for measuring vehicle load and a measuring and computing method, relates to the fields of transmission systems of measured values, control signals oranalog signals and data processing, particularly a vehicle-mounted terminal for measuring vehicle load and a computing method of vehicle load. The vehicle-mounted terminal comprises a CAN collectionmodule, a parameter storage module, a computing module, a six-axis sensor, a communication module and a GPS / BD positioning module, wherein the CAN collection module is connected with the parameter storage module and the computing module respectively; the six-axis sensor is connected with the computing module; and the parameter storage module, the computing module and the GPS / BD positioning moduleare connected with an external remote monitoring platform through the communication module respectively. The terminal is connected with vehicle CAN for collecting vehicle model information; vehicle parameters are inquired; vehicle VIN codes are collected; the current vehicle position information is collected by using the GPS / BD positioning module, the road condition and weather condition of current position are requested, and corresponding values of related parameters are updated; and the vehicle driving data is collected by the CAN communication module and the six-axis sensor.

Description

technical field [0001] The invention relates to a vehicle-mounted terminal for measuring vehicle load and a measurement and calculation method, which relate to the field of transmission systems and data processing of measured values, control signals or similar signals, in particular to a vehicle-mounted terminal for vehicle load measurement and a calculation method for vehicle load. Background technique [0002] In recent years, with the rapid development of technology and economy in modern society, the number of cars owned is also increasing year by year. While automobiles bring convenience to people's travel, they also lead to aggravation of environmental pollution. The impact of automobiles on environmental pollution is mainly in two aspects: sound pollution and exhaust pollution. When the vehicle load is large, in order to obtain greater traction power, it is often used to drive with a low gear and a large throttle. When driving with a low gear and a large throttle, th...

Problems solved by technology

[0005] The purpose of the present invention is to provide a vehicle-mounted terminal for measuring vehicle loads in order to overcome the problems of the existing real-time vehicle load monitoring technology that the load accuracy is greatly affected by the strength of the positioning signal, the error caused by the inconsistency between the preset parameters and the actual vehicle conditions, and poor applicability. The vehicle load measurement and calculation method uses the remote monitoring platform to update the vehicle parameters required for calculating the vehicle load in a timely manner, collects the dynamic data required for calculating the vehicle load through the vehicle terminal, and can estimate the vehicle load at any time according to the needs, solving the current inaccurate Real-time monitoring of vehicle load problems, providing judgment data for traffic, environmental protection and safety supervision departments
