About the technical scheme of the project

Description:
Description:
Information

  The core of the management platform of the Internet of things for PSA equipment includes two aspects: one is the real-time monitoring of the production and operation status of the PSA equipment, including the monitoring of the operation efficiency and efficiency of the PSA equipment, and the real-time monitoring of the safe operation of the PSA equipment; the other is the business integration information platform with the operation of the PSA equipment as the core, including the PSA equipment The whole life cycle management of adsorption device, spare parts management of pressure swing adsorption device, and on-site operation personnel management are all informationized.
  1. Scheme architecture: PSA IOT solution defines four basic network elements in equipment IOT.

  1.1 field sensor layer
  On site temperature, pressure, flow and composition analysis instruments are all intelligent instruments with upload function, and programmable logic control system is installed on site to transmit all instrument signals to PLC for engineering quantity conversion. It is equipped with remote control actuator, which can accept PLC data automatic control action. An industrial computer is installed in the central control room, and the process picture of PSA device is configured on the industrial computer, and the process parameters and alarm information of each key node are directly displayed.

  1.2  Adapter (aprus)
  Through docking with PLC and IPC, aprus data adaptation terminal collects various operation status, event, alarm, setting, request / control data of PSA device, and uploads them to basic data platform through 2G / 4G / Ethernet / WiFi。

  1.3  Basic data platform (gards)
  Gards universal asynchronous remote data service. Gards receives and saves the data sent by the adapter, arranges, organizes, correlates and analyzes the data, maintains a series of logical rules and forms a series of conditional trigger mechanisms, sends information (data) to the adapter, and provides the data of gards system to other application systems.

  1.4  Application system (fidis)
  Fidis flexible information and data integration service. Combined with the user's application requirements for data, the fidis system displays the data concerned by users and carries out corresponding business management, such as equipment real-time operation monitoring, equipment asset management, whole life cycle management, maintenance work order management, etc., and supports different ways of display, such as PC, large screen, app, etc.


  2. System application function
  The basic data platform gards obtains the data sent by the adapter. After classifying, organizing, standardizing and associating these data, it can be used conveniently and flexibly in fidis application system, such as remote real-time monitoring of equipment, fault warning, maintenance order management, equipment life cycle management, historical data query, etc.
  2.1  Real time monitoring subsystem
  Through fidis application system, the real-time operation data, fault information and on-site video of all equipment can be known on PC, app or large screen. Fidis can display and count the equipment online rate in real time, view the equipment operation details, query the historical data, and monitor the important indicators and parameters of the equipment in real time. The monitoring data include: status data, event data, fault data, alarm data, etc.

  2.2  Equipment integrated management subsystem
  Through fidis, all equipment can be managed comprehensively, and online supervision, geographical distribution statistics and fault statistics of equipment can be achieved. The field parameter setting, on-off and other operation records of the equipment can also be displayed on fidis platform.

  2.3  Fault alarm subsystem
  The system supports monitoring the switching value and setting the data threshold value. If the maximum and minimum value is set, the alarm will be given automatically when the threshold value is exceeded. At the same time, the fault alarm can be triggered automatically, and the relevant management personnel can be informed by the form of screen flick, SMS or telephone call (the associated person will be informed by SMS when the power is off). Fault alarms are mainly divided into the following two categories;
  1) Real time fault alarm: real time report the fault information collected by the control system;
  2) Fault early warning: when the equipment operation parameters exceed the predetermined data threshold, an early warning prompt is generated, for example, the main parameters are abnormal, the service life is over limit, and so on.

  2.4  Work order management subsystem
  The maintenance personnel can query the work order according to the work order acceptance time, serial number, work order type, work order status, calling number, business type and other information, and view the detailed processing of the work order.
  In the process of work order circulation, maintenance personnel can be reminded to process work orders in a variety of ways. It supports the setting of work order processing time limit, work order urgency and relevant personnel to be reminded. Before reaching the time limit of work order processing, the system can regularly remind the maintenance personnel to deal with the work order in time according to the urgency of the work order; if the time limit of work order processing has been reached but the work order has not been processed, the system will automatically generate a yellow card alarm to urge the maintenance personnel to deal with it by way of alarm.

  2.5  Statistical Report Subsystem
  The system can display the historical data of different types of equipment through graphics, lists and other ways; it can improve the efficiency of data analysis by establishing mathematical models, and set logic and operation rules to carry out data calculation, statistics and analysis, and automatically generate statistical reports, such as economic operation report, energy consumption monitoring report, equipment physical examination report, etc。

  2.6  Life cycle management subsystem
  Firstly, the system will file each equipment, the file information includes equipment name, location, model, specification, drawing file, etc., and carry out unified and centralized management of various data information, such as the service life of key components, spare parts information, etc. At the same time, the historical operation and maintenance parameters, fault handling records and other knowledge documents of each equipment are archived and managed. Through the whole life cycle management subsystem, the key business such as equipment operation, patrol inspection, repair / maintenance, overhaul and so on are managed in a unified information way; the operation specifications and operation standards of various businesses are set; the whole process of air compressor maintenance is monitored comprehensively; the efficiency of equipment operation and management is improved: the maintenance personnel receive the orders, upload the maintenance records, update the maintenance information, and update the maintenance information Collect spare parts and related materials according to the order.

  2.7  Historical data
  The historical operation data of all equipment can be traced, and the data can be presented by broken line, curve and other ways.

  2.8  Authority management
  You can assign sub accounts, set different accounts, and set permissions of different roles.
