Vehicular LNG (liquefied natural gas) cylinder measurement information remote monitoring system and vehicular LNG cylinder measurement information remote monitoring method

Abstract

The invention discloses a vehicular LNG (liquefied natural gas) cylinder measurement information remote monitoring technology. A transmitting device comprises an acquiring and processing module and a GPRS (general packet radio service) module; the acquiring and processing module is used for acquiring and processing measurement information; the GPRS module is communicated with a remote host end; the remote host end comprises internet connecting equipment, a host server, a database server and a client; the host server is communicated with the transmitting device through the internet connecting equipment; the measurement information is stored by the database server; the measurement information is stored in the database server in an XML (extensive markup language) text formatting mode, and is transmitted between the host server and the database server through information requesting and responding; XML texts are transmitted between the client and the host server through XML text requesting and responding; the client operates so that the XML texts are displayed into HTML (hypertext markup language) texts; and the HTML texts are shown as the measurement information in a web page mode by the client. By the vehicular LNG cylinder measurement information remote monitoring technology, the measurement information of the spot transmitting device for gas cylinders can be monitored by a web page end of the client, and the information of the gas cylinders can be dynamically displayed on web pages.

Description

technical field [0001] The present invention relates to the communication technology between the on-site device and the centralized control master station of the LNG (liquefied natural gas) cylinder used for the fuel supply of the vehicle transmitter, and particularly relates to the remote monitoring system and method for the measurement information of the LNG cylinder for the vehicle . Background technique [0002] The cost of LNG fuel is low, the main component is methane, and there are few harmful components after combustion. It has been widely used as engine fuel in large and heavy vehicles. LNG cylinders contain low-temperature and high-pressure liquefied natural gas. The monitoring of its liquid level, pressure and temperature is indispensable for the safe use of the cylinders. The related measuring equipment can transmit the measurement signals through wired transmission. In the cockpit for the driver to monitor, but only the driver monitors the gas cylinders in the ...

Problems solved by technology

LNG cylinders contain low-temperature and high-pressure liquefied natural gas. The monitoring of its liquid level, pressure and temperature is indispensable for the safe use of the cylinders. The related measuring equipment can transmit the measurement signals through wired transmission. In the cockpit for the driver to monitor, but only the driver monitors the gas cylinders in the vehicle, the comprehensiveness of the information on the gas cylinders in the vehicle is not enough, and the driver lacks the understanding of the measurement technology, and the measurement data is easily misunderstood. Operating errors, missed rescue opportunities in the danger warning stage, but currently lacks centralized monitoring technology for on-site data associated with physical state changes of LNG cylinders used in moving vehicles
