Real-time monitoring system of bus gas storage based on on-board data

Abstract

The invention discloses a bus gas storage quantity real-time monitoring system based on onboard data. The system comprises a controller, a temperature sensor for measuring the outside environment temperature of a gas cylinder, a pressure sensor arranged in the gas cylinder and used for measuring the pressure in the gas cylinder, and a GPRS (General Packet Radio Service) module, wherein the temperature sensor and the pressure sensor transmit the acquired data to the controller, and the controller processes and stores the received data information and further transmits the processed information to a monitoring center through the GPRS module. The system acquires the environment temperature and the pressure data in the gas cylinder, processes the acquired data through the controller and calculates the gas storage quantity in the gas cylinder, and further transmits the calculated gas storage quantity to a far-end monitoring center through the GPRS, so as to monitor the gas consumption of the bus in real time and provide an important basis for the bus company to manage the bus fleet and research economic drying behavior.

Description

technical field [0001] The invention relates to a system for monitoring the gas storage capacity of buses. Background technique [0002] At present, as the most important mode of transportation in big cities, the safe, economical and comfortable driving of buses has attracted widespread attention. Natural gas is used by most buses due to its safety, high efficiency, stable combustion, clean and environmental protection. In the process of bus operation, the real-time monitoring of bus gas consumption provides an important basis for bus companies to manage fleets and study economic driving behavior. [0003] At present, there is no research report on the real-time monitoring system of bus gas storage network based on vehicle data. Wang Chijun and others have developed an online vehicle dynamic fuel consumption detection system, which is used to obtain the instantaneous fuel consumption of the vehicle, but remote monitoring cannot be realized. Sun Peng developed a gas storag...

Wang Chijun and others have developed an online vehicle dynamic fuel consumption detection system to obtain the instantaneous fuel consumption of the vehicle, but remote monitoring cannot be realized

Sun Peng developed a gas storage measurement method and device for natural gas vehicle cylinders, but did not specify the specific installation method of the temperature measurement device and the use of temperature parameters, and could not judge the magnitude of the gas storage estimation error, and did not pass the measurement results through the network. Real-time monitoring cannot reflect its practical application value; however, due to the inherent noise interference of the on-board system, it is difficult to guarantee its effectiveness by directly using these data to estimate the gas storage capacity
