Data collection cabinet

Abstract

The invention belongs to the technical field of the intelligent water supply temperature control construction of the water resources and hydropower engineering, and provides a data collection cabinet.The data collection cabinet comprises a cabinet body, a wiring device, a collection module, a central processing module and an external module; the wiring device is used for mounting the collection module, the central processing module and the external module; the collection module is used for collecting flow of a heat exchange medium, the temperature of the inlet-outlet heat exchange medium andthe concrete block temperature in an integrated control cabinet; the central processing module uploads the collected data to a cloud server to perform data interaction; and the central processing module controls the flow of the heat exchange medium by adopting a gradient intelligent closed-loop learning control method, thereby realizing the controlling on the highest temperature, the adjusting onthe cooling rate and the diagnosis on the abnormal temperature of a controlled object. The data collection cabinet disclosed by the invention has the advantages of being anti-interference, capable ofcontinuously, stably and efficiently running, and performing the data collection, analysis and control in real time.

Description

technical field [0001] The invention belongs to the technical field of intelligent water supply and temperature control construction of water conservancy and hydropower projects, and in particular relates to a data acquisition cabinet. Background technique [0002] In the traditional on-site control involving a variety of equipment, due to the large amount of equipment installed and many wirings, it is easy to have problems such as messy lines, inconcentrated functions, and intermittent data uploading, resulting in weak control, control distortion, and inconvenient troubleshooting and maintenance. . [0003] In order to solve the above problems, in 2012, China Energy Construction Group Co., Ltd. (formerly Gezhouba Group Test and Inspection Co., Ltd.) applied for the patent CN202443315U, and proposed a multi-channel online concrete cooling water flow automatic data collection device, including a power module, Temperature acquisition module, data acquisition module, main cont...

AI Technical Summary

Problems solved by technology

[0009] (1) The wiring is messy and the functions are not concentrated, which cannot meet the complex construction environment on site, and the installation workload of the site equipment is heavy, there are many wirings, the equipment is easy to be damaged and stolen, and it is not easy to troubleshoot and maintain;

[0010] (2) The data acquisition cabinet in the prior art cannot be reused as a whole, it needs to be disassembled and installed, and disassembled again after installation, which is inconvenient to operate

[0011] (3) The opening of the circuit cannot be pre-set in batches, which will delay the construction progress

[0012] (4) The data acquisition equipment and the control equipment are separated, the equipment is basically not interconnected, the scalability is poor, it cannot work independently, and it cannot work when the network is disconnected, which brings difficulties and inconveniences to control the temperature of the dam concrete

[0013] (5) The on-site data upload is easily interrupted, and the data is distorted, resulting in poor temperature control and poor adjustability of the cooling rate, resulting in easy distortion of the control
