The system adopts an up and down position mode to detect toxic and flammable gases. The upper position of the system adopts high-performance industrial control computers, and the lower position adopts our company's independently developed toxic and flammable gas alarm controller and detector. The computer monitoring software adopts an intuitive and easy-to-use human-machine interface, data processing, and automatic control. Gas detection and control are achieved in the monitoring room through the upper position. Reserve an interface for connecting to the user's MIS network on the computer. Equipped with networking function, it can be connected to other microcomputers through the Internet to achieve remote monitoring and control.

The combustible gas alarm controller and detector are directly connected to the industrial control computer through RS485 bus, and virtual instruments are generated in the industrial control computer;

◆

Integrated with functions such as data collection, storage, and querying: The workstation host can receive signals from combustible gas alarm controllers and detectors and form virtual instruments, replacing traditional data collection systems to complete functions such as system diagram display, virtual instrument display, historical data query, report generation, and printing;

◆ Implement information network publishing: The workstation forms various information into web pages, and through advanced B/S structure, enables network publishing, network querying, and interaction;

A fully digital, multi parameter, bidirectional, and multi site RS485 bus communication network.

● Data acquisition: Analog and digital acquisition functions

Control signal output: analog and digital output functions.

Data storage and processing: Data is stored in standard database format, and the amount of data saved is only limited by the computer's hard disk space.

● Manual output: Online random input editing function for manually analyzing data.

Real time display: including multiple display modes such as virtual instruments, data tables, curves, etc., can be switched freely: dynamic display of analog quantity summary table for a single unit and page switching between units.

Real time alarm function: It has the real-time alarm function of collecting data, prompting pop-up window screen to display text and red flashing alarm, and outputting sound signals to the speaker through the computer sound card to sound the alarm.

Alarm records and queries: Alarm parameters can be recorded as historical records, and alarm history records can be queried based on conditions.

Real time curve display: instantaneous curve display of each parameter.

Historical curve display: Multiple parameters of historical curves can be retrieved at any time period, and the curves can be enlarged and displayed.

Report management: Random printing of hourly, daily, and monthly reports, as well as timed printing of reports and curves.

Range and alarm limit settings: Users can modify and set the range and alarm upper and lower limits of the collection points online through software.

● Instrument management function: The on/off function of detectors and controllers, with instrument running time statistics function, and the ability to print statistical reports.

User permission management: Users can be assigned permissions and time limits based on their preferences, with user levels ranging from 0 to 999 and any time limit assigned. A password management system is used.
