Interlock System
The working principle of Shanghai Jiehao's interlock system is through the cooperation of software and hardware to control the opening state of the doors. For example, when one door is opened, the other door is locked to prevent them from being opened simultaneously, which prevents external contaminants from entering the clean area. The interlock system can be a two-door interlock, a three-door interlock, or an interlock of more doors. Jiehao's interlock does not use integrated circuits but instead employs a programmable PLC system designed according to actual application needs.
In addition to preventing cross-contamination, Jiehao's cleanroom interlock system also has the following functions:
1. Modular and Standardized Operation:
Supports modular and standardized cleanroom operation panels and controllers, allowing the system to be customized and expanded according to specific needs.
2. Distributed Networking Capability:
Capable of achieving distributed networking of controllers via Ethernet, supporting the remote and simultaneous interlocking of over 100 doors, enhancing the system's flexibility and scalability.
3. System Integration:
Can be integrated with access control, fire protection, MES (Manufacturing Execution System), and other systems through the accompanying linkage controller, improving the automation and intelligence level of cleanroom management.
4. Programmable Cloud Controller:
Provides a variety of distributed IO Ethernet modules for flexible networking, and supports five PLC development languages of the IEC 61131-3 standard, facilitating joint debugging and unified programming.
5. Real-time Data Monitoring and Alarm:
Capable of directly sending the real-time values of controller variables to the cloud for convenient mobile browsing and big data storage, and has the function of directly sending WeChat for parameter alarms, ensuring real-time monitoring and rapid response.
6. Standard Communication Protocol:
Provides the standard MODBUS TCP communication protocol for easy integration with third-party industrial touch screens and SCADA (Supervisory Control and Data Acquisition) systems, enhancing the system's compatibility and integrability.
These functions together ensure the safety, reliability, and efficiency of Jiehao's cleanroom interlock system in practical applications.
