Radio data monitor

Abstract

A radio data monitoring apparatus is composed of a data collection module, a radio communication module connected with the data collection module via a signal chip machine module, the single chip machine module, and a display module and an application module connected with the single chip machine module separately. The work information of temp., pressure and flow rate is collected by the transducer in the data collection module, is converted into 0-5 V analog voltage, into standard voltage output via LM324 conversion. The standard voltage output is received by integrated block 89C 196, is converted to temp., pressure and flow rate via A / D conversion and is transmitted in the radio communication module using standard ACCII character. The data from each monitoring point is transmitted to the monitoring center in radio mode via GSM network.

Description

Technical field:

[0001] The invention belongs to the technical field of electronic communication, and relates to a monitoring instrument for centralized monitoring of low-speed data by means of wireless communication. Background technique:

[0002] In oil fields, electric power, heating power, gas, tap water, water conservancy and other departments, there are many places with wide geographical distribution and relatively harsh environments, and it is necessary to constantly understand the operating status of their instrumentation equipment, monitor and control temperature, pressure, and flow. The best method is to require special staff to guard the site or conduct on-site inquiries and operations on a regular basis. However, the existing monitoring system adopts wired transmission mode or cluster transmission mode, which has problems such as large investment, slow effect, inflexible networking, and limited geographical area, and is not widely used at present.
