According to the company's system technical requirements for a company's use of the CO2 control system at Shanghai Xuhui station, the relevant technicians of our company have conducted a careful study of your company's system. The control scheme of the control system and its composition are as follows:
First, the user needs:
1. The use of an addressable carbon dioxide sensor, each carbon dioxide sensor with a specific address is marked.
2. Carbon dioxide is collected in four ways and the purification device is distributed in eight ways. Each carbon dioxide control device can control two sets of purification devices
3. Each CO2 sensor can be individually controlled, each sensor can set upper and lower limits (peak), each carbon dioxide sensor interval can be adjusted.
4. The working status of the purification device can be monitored and reacted to the workstation. (Pe)
5. The history of main parameters is maintained for 3-5 years
6. Turn on the password (software)
7. The software must include the following items:
Negative ion generation
Detection value
Probe status
Sampling problem
Start delay
8. Working status has automatic and manual modes
9. Monitoring setting item addition
(1) Has a timer setting function
(2) Data backup operation function
(3) Abnormal alarm function of sensors and purifiers
10. Controller closed installation
Household trademark:
Air Purifier Control Center
Second, the system plan
The system uses an industrial-grade color LCD panel computer as a control host, and a switch data acquisition card to control the air purification system.
System Components:
1. Hardware:
a. Industrial Control TONREN-PPC-10.4"-B
TONREN-PPC-10.4â€-B is an industrial computer, and TONREN-PPC-10.4â€-B expands into a flat one-piece workstation due to the customer's demand for internal board cards. It has built-in high-reliability industrial-grade motherboards and industrial-grade standard passive master boards. Flexible ISA/PCI device expansion based on user applications. 10.4-inch high-brightness LCD display with high-strength wear-resistant touch screen can meet various applications based on PC in industrial environment.
