Remote program updating device for data acquisition and transmission instrument

Abstract

The invention discloses a remote program updating device for a data acquisition and transmission instrument. The remote program updating device comprises DTU (Data Transfer Unit) wireless data transmission equipment connected with the data acquisition and transmission unit, and a host computer, wherein the DTU wireless data transmission equipment achieves bidirectional remote communication with the host computer through both a GPRS (General Packet Radio Service) network and an Internet network, and one DTU wireless data transmission equipment is connected with one or more data acquisition and transmission instruments; the data acquisition and transmission instrument comprises a sensor module, a signal conditioning module connected with the sensor module, a processor module I connected with the signal conditioning module, a data storage module connected with the processor module I, and a power supply module I; and the DTU wireless data transmission equipment comprises a processor module II, and a GPRS module and an equipment security monitoring module which are connected with the processor module II, as well as a power supply module II. The remote program updating device for the data acquisition and transmission instrument has the advantages of reasonable design, low transmission cost, high program updating speed, convenience in implementation, wide application range, high practical value, and convenience in popularized application.

Description

technical field [0001] The invention belongs to the application technical field of data acquisition and transmission instruments, and in particular relates to a remote update device for programs of data acquisition and transmission instruments. Background technique [0002] In today's various data acquisition systems, the data acquisition and transmission instrument is a key device that can upload the data collected at the monitoring point to the monitoring station. It not only plays the role of data forwarding and transmission, but also plays a role in the monitoring point sensor network The most important thing is that it controls the transmission format of the reported data, the reporting time point, etc. It can be seen that whether the data acquisition and transmission instrument is running well or not plays a vital role in the quality and effectiveness of the entire data acquisition. In order to enable the data acquisition and transmission instrument to adapt to its op...

Problems solved by technology

The most direct method is for professionals to go to the site where the data acquisition and transmission device is installed, and establish a physical connection between the data acquisition and transmission device and the PC. Although this method can eventually realize the file transfer with the data acquisition and transmission device, there are obvious problems. Insufficient, mainly reflected in: Professionals must go to the installation site, which will inevitably lead to an increase in transmission costs, the most critical thing is that this method is not upgraded in time
