Heat transfer station monitoring recording device based on accumulator read-in module (ARM)

Abstract

A heat transfer station monitoring recording device based on an accumulator read-in module (ARM) comprises an ARM11, a video camera, a touch screen colorful liquid crystal display, an upper computer and a single chip microcomputer system. The ARM11 collects images in the heat transfer station running process through the video camera, utilizes the colorful liquid crystal display to display the images, stores the images into a secure digital (SD) card, and is connected with the upper computer through a general package radio service (GPRS) module or an Ethernet port with the upper computer. The single chip microcomputer system is connected with an ARM11 port to transfer water supply temperature, water discharge temperature, valve openness and the like in the running process of a heat transfer station device. The heat transfer station monitoring recording device improves safety running efficiency of the heat transfer station, and is compact in integral structure, less in material consumption, long in service life, low in cost, stable and reliable in performance, convenient to maintain and suitable for being used by heating construction departments.

Description

technical field [0001] The invention relates to an ARM-based intelligent recording and online monitoring system, in particular to a data recording and safety performance analysis device specially used in conjunction with heat exchange station equipment. Background technique [0002] At present, there are mainly three types of research and development of monitoring and recording devices for heat exchange stations: one is the electronic analog type, which uses a large number of analog circuits to process and calculate sensor signals, and uses analog meters to display. The disadvantages are low precision and difficult design and maintenance. , fragile, has been phased out. The second type is the digital type, which is the most commonly used type at present. Its characteristic is that the complex calculation work is all completed by software, the integration degree and comprehensive accuracy of the system are improved compared with before, and the system has a self-test function...

Problems solved by technology

[0003] From the perspective of practical application technology, although it has been a research problem for many years, it is still mainly focused on finding a new effective signal decomposition and extraction method based on the analysis of actual working condition signals, so that the processing can provide a basis for judging the safety performance of the heat exchange station , so in our country, it is very important to timely overhaul to eliminate potential failures of key equipment, but for a developing country, my country's current preventive regular maintenance and equipment maintenance system that runs until damaged and then repaired can no longer meet the requirements of modern production. There are two main objective reasons for this situation. On the one hand, the working process of the heat exchange station has strong coupling and large lag, and the operation is difficult; on the other hand, the recorder of the heat exchange station that can realize online detection is relatively expensive. The economic affordability of most small and medium-sized enterprises is limited, and these two aspects greatly limit the accurate operation of the heat exchange station.
