Bus monitoring host data acquisition method and bus monitoring host data acquisition system

Abstract

The present invention relates to a bus monitoring host data acquisition method and a bus monitoring host data acquisition system. The method includes the following steps that: data transmission, memory buffering and local storage are carried out on acquired data concurrency; network state monitoring is carried out in the processes of data transmission, memory buffering and local storage; when a network connection is abnormal, network state monitoring is carried out continuously until the network connection returns to normal; if the memory capacity of a monitoring host can satisfy a requirement for complete storage of data acquired in a network anomaly period, data stored in the memory of the monitoring host in the network anomaly period are transmitted supplementarily; and if the memory capacity of the monitoring host cannot satisfy the requirement for complete storage of the data acquired in the network anomaly period, data stored in a local large-capacity memory in the network anomaly period are transmitted supplementarily. The system includes a main control unit as well as a data acquisition module, a data storage module, a data transmission module, a data supplementary transmission module and a communication module which are connected with the main control unit. With the method and system of the invention adopted, it can be ensured that data will not be lost in a network outage situation, and the reliability of the monitoring host can be greatly increased.

Description

technical field [0001] The invention relates to the field of passenger car monitoring, in particular to a data acquisition method and system for a passenger car monitoring host. Background technique [0002] The existing remote monitoring host mainly transmits data through wireless communication, and can control the vehicle-mounted terminal through the wireless network to realize two-way data transmission between the mobile vehicle and the monitoring center, and complete the monitoring of the vehicle's operating status, safety status, and technical status . Its monitoring reliability is limited by network communication quality, bandwidth, etc., low communication efficiency, low reliability, high communication costs, low collection frequency, and limited availability, which are far from meeting the safe operation needs of new energy buses. [0003] The existing monitoring host does not compress the data, so the storage data redundancy is large, the availability is low, and t...
