Data acquisition and transmission terminal of LNG vehicle gas cylinder and application method thereof

Abstract

The invention discloses a data acquisition and transmission terminal of an LNG vehicle gas cylinder and an application method thereof. The terminal comprises a shell, wherein a PCB is arranged in theshell; the PCB is provided with a communication module, a positioning module, a power module, a bus module, a main control chip, a temperature acquisition module, an A / D module, an AI module and a DImodule; and a GPS / BD interface, a 485-1 interface, a 485-2 interface, a CAN interface, a DI / 1 interface, an AI-Q / 4 interface and an AI-T / 3 interface are arranged outside the shell wall. The data acquisition and transmission terminal achieves multiple serial applications through the 485-2 interface so as to achieve various application scenarios of the LNG vehicle gas cylinder, such as single cylinder for single vehicle, double cylinder for single vehicle and three cylinders for single vehicle, so that the needs of various configuration forms are met, the safety and the management convenience are greatly improved during using the vehicle gas cylinder, and therefore, the supervision efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of Internet of Things and data acquisition technology for gas cylinders used in liquefied natural gas vehicles, and in particular to a data collection and transmission terminal for gas cylinders used in liquefied natural gas vehicles and an application method thereof. Background technique [0002] Liquefied natural gas vehicles refer to vehicles powered by liquefied natural gas, which have been widely used in recent years due to their good environmental protection and economy. The gas cylinder for liquefied natural gas vehicles is a low-temperature heat-insulated pressure vessel that is used to replace automobile fuel tanks for filling and storing, and to supply automobile fuel, and can be refilled many times. LNG vehicle gas cylinders are scattered and distributed due to the transportation and driving of LNG vehicles, especially the vehicle gas cylinders that move with the vehicle, which are often affected ...

AI Technical Summary

Problems solved by technology

LNG vehicle gas cylinders are scattered and distributed due to the transportation and driving of LNG vehicles, especially the vehicle gas cylinders that move with the vehicle, which are often affected by external unsafe factors, have a high safety risk factor, and are difficult to supervise

At present, the vehicle gas cylinders in use do not have data collection and transmission terminal applications specifically for various usage status and safety status, and cannot realize remote real-time monitoring, nor can effective safety control be implemented; and the vehicle gas cylinders that were applied earlier on the market And the coexistence of new application gas cylinders, the coexistence of different types of gas cylinders from different manufacturers, the coexistence of vehicle gas cylinders with different forms and types of gas cylinder sensors or instruments, and many application forms such as "one cylinder for one vehicle" and "two cylinders for one vehicle", etc. How to use a single device to implement fast compatible applications, collect and effectively transmit the above-mentioned vehicle gas cylinder data information in different scenarios, types, and applications is a blank in the existing application technology
