Abstract

The invention discloses a Portable serial data recorder for collecting and recording the data of the industry on-site device, the traffic line on-site device and the geographic exploration on-site device, which comprises the following parts: a RS232 serial line interface receiving modular and a RS422 serial line interface receiving modular for collecting the data of on-site device RS232 interface and RS422 interface, a Secure Digital saving card for saving the acquired data, a FAT16/32 file system for recording the data with the file form in the Secure Digital saving card, an USB communication modular for transferring the data to the computer by USB protocol, a power and a Li-ion battery modular for providing the needed electronic energy. The data recorder achieves the analysis and dealing of the on-site data off the site environment.

Description

technical field [0001] The invention relates to a portable serial data recorder and its implementation method, belonging to the technical field of collecting and storing data generated by on-site electronic equipment in the fields of industry, transportation, and geographic surveying and mapping. Background technique [0002] In the field of industry, transportation, and geographical surveying and mapping, the application of computer technology and electronic technology is becoming more and more extensive. Field devices have a large amount of data to be processed, such as operating data and diagnostic data of industrial control equipment, traffic flow collector data, railway Interlocking status data of station equipment, working data of interval control equipment, GPS detection data of surveying and mapping areas, etc. Many of these devices are not connected to the network. If the control center or laboratory needs to obtain the working data of these devices, they need to se...
