1. Project background
A certain beer equipment manufacturer in Qingdao is a manufacturer specializing in the production of beer supporting equipment, and the sterilization machine is one of the key hosts on the beer packaging production line. Its main task is to kill the yeast and other miscellaneous bacteria remaining in the liquor to ensure The biological stability of beer makes it conducive to long-term storage. Usually PU value (that is, pasteurization unit, where the sterilization effect caused by 60°C for 1 minute is 1 PU value) to express the depth of sterilization. Insufficiency or excessive will have an impact on the shelf life and flavor of beer, so controlling the PU value within a certain range is the main technical index of the sterilizer. The temperature directly affects the PU value, so it is a problem that the company needs to solve to realize the temperature control by remotely controlling the PLC.
2. Huachen Zhitong’s PLC-based remote monitoring solution for sterilization machines
This solution connects the HiNet industrial intelligent gateway module independently developed by Huachen Zhitong to the PLC of the sterilization machine through wired or wifi, 3G and other wireless methods to receive and monitor various data of the PLC. The value of the sterilization zone is transmitted to the HiCloud cloud server, and the customer receives the data remotely on the company’s computer or mobile phone. The Hinode windows Client and PLC programming software can be used to achieve remote programming and debugging.
Third, the functions that can be realized by the remote monitoring program of the sterilization machine based on PLC
1. Realize the functions of PLC remote programming and debugging, uploading and downloading, etc.
2. Remote monitoring and control adjust the speed of the sterilizer host, the temperature of each temperature zone of the sterilizer, etc., to realize the normal and stable operation of the sterilizer
3. Realize the collection and analysis of data such as the on-site temperature of the sterilizer
4. Realize the fault diagnosis and analysis function of the remote sterilizer
5. Real-time and historical curve display: real-time curve display and historical record curve display of the PU value of beer in the number of users in the temperature zone
6. System alarm: alarm the upper and lower limits of temperature and the upper and lower limits of water pump pressure for each temperature zone under temperature control.
7. Historical reports: When historical data reports are needed, corresponding operations can be performed to generate Excel historical reports for technical personnel to process and analyze.
8. Parameter group management: can manage production parameter recipes, quickly store and read parameter sets.
9. User level protection: Multi-level users and corresponding passwords can be set, and different levels can only be operated at corresponding levels.
Fourth, the benefits that can be achieved by applying the PLC-based remote monitoring program for the sterilization machine
1. Save enterprise after-sales cost, reduce labor cost and travel cost, etc.
2. Improve corporate service quality and increase customer satisfaction
3. Improve the competitiveness of enterprise products and increase enterprise benefits.
