Digital heating pipeline monitoring system

Abstract

The invention discloses a digital heating pipeline monitoring system which comprises an industrial control upper computer and a plurality of detection nodes. Each detection node comprises a plurality of temperature sensors and a single-chip lower computer. The industrial control upper computer and the detection node respectively comprise a set of wireless transceiver circuit. Each temperature sensor is used for detecting the temperature of a heating pipeline, and transmitting detected temperature signals to the single-chip lower computer. The single-chip lower computer conduct pre-processing on the received temperature signals, and then the detected temperature signals are transmitted to the industrial control upper computer through the wireless transceiver circuit. The industrial control upper computer receives temperature data transmitted by each detection node in real time, the temperature data are displayed onto a pipe network diagram, the temperature valve and changing valve of each sensor are recoded at the same time, internal temperature distribution profiles of the detection nodes are generated, and temperature variation comparison diagrams of the temperature sensors are generated. The digital heating pipeline monitoring system can rapidly and effectively identify fault points.

Description

technical field [0001] The invention relates to a pipeline monitoring system, in particular to a digital heating pipeline monitoring system realized by computer technology. Background technique [0002] Pipeline construction is generally buried deep underground as a concealed project, and because the units undertaking the project are distributed in various places, the project implementation personnel have a high mobility, and the quality and level of personnel are different, so pipeline failures are inevitable. Once a fault occurs during pipeline operation, it is difficult to determine the fault point, so the cost of manpower and material resources will be very considerable. [0003] During the operation of long-distance hot steam pipelines, they are usually affected by the internal and external environments, resulting in damage to the pipelines and loss of heat energy. The rupture of the inner pipe is mainly caused by the combination of high temperature and high pressure h...

And the double-layer hot air pipe (see figure 1 ) There is currently no good way to detect inner pipelines

[0006] At present, the common method of double-layer inner pipe detection is to install the air outlet at a unit of 50 meters. Once the inner pipe ruptures, high-temperature steam will be ejected from the air outlet through the steel protective pipe. Therefore, it can be determined that the fault is within the 50-meter unit and reported by the masses. Or full-time personnel inspect and find the faulty unit, and then organize personnel to dig a pit for inspection. Generally, it takes three or four excavations to find the fault point. For the excavation and landfill project, the cost per meter exceeds 10,000 yuan, and it also needs to go through multiple departments. Approval can be said to be a waste of money and time, and the loss of heat loss caused by the delay is also considerable.
