◆System Introduction The main equipment on a sugar mill's pressing production line includes a sugarcane cutter, a press and its drive unit, a percolation system, and corresponding conveying equipment. Sugarcane needs to be pressed multiple times through several three-roll presses: before entering the last press, water is added for percolation; this water is called percolation water, and the juice extracted from the last press is called last press juice. This juice is then pumped to the previous press as percolation liquid, percolating the sugarcane entering that press. The diluted juice extracted by the press is then used as percolation liquid for the previous press, and so on until the second press. This is a common double percolation method used in sugar mills. The juice from the first and second presses is combined into a mixed juice and sent for purification treatment; the sugarcane discharged from the last press is called bagasse, which is sent to boilers as fuel or used as other industrial raw materials. This system mainly monitors the operating parameters of the equipment on the pressing production line, including the temperature of the front and rear bearings of the press, the oil temperature at the outlet of the lubricating oil cooler of the press gearbox, the temperature of the shredder, and the current. ◆System Design I. System Overview This system utilizes the "INSPEC" general-purpose configuration software. Its control system employs 10 temperature acquisition modules (Adam4015) and 1 current acquisition module (Adam4017), communicating via RS-485 serial communication. The temperatures of the front and rear bearings of presses 1-5 and the temperature of the shredder of presses 1-3 are collected from on-site temperature sensors via the 10 Adam4015 temperature acquisition modules. The current of the shredder of presses 1-3 is collected from on-site current sensors via the current acquisition module. "INSPEC" communicates with the Adam4015 and Adam4017 via RS-485 serial communication to monitor the temperature and current of the equipment on the pressing production line. II. System Composition Diagram ◆Main Functions of the Software System This monitoring system adopts a "data acquisition-computer monitoring" approach. The monitoring computer displays the temperature digitally in real time. The system also possesses rich functions such as data processing, data storage, and trend analysis. 1. Operators can monitor the temperature of the front and rear bearings of presses 1-5 and the temperature and current of the shredder of presses 1-3 via a monitoring computer. 2. Realistic animations display the real-time operation of the pressing production line, such as the rotation of the bearings of presses 1-5, allowing operators to have a clear understanding of the entire pressing process. 3. Real-time temperature reports display the recorded temperature and current values ​​in tabular form. 4. Real-time trend curves and historical trend curves. 5. Alarm records, etc. When an alarm occurs, the system automatically writes the alarm information to the alarm storage file. The alarm information can be displayed in real-time in the alarm window according to the set filtering conditions. When the temperature or current reaches the upper limit, the alarm text turns red, and an alarm record pops up.

Through the use and actual on-site debugging and operation of the "INSPEC" general-purpose configuration monitoring system, users highly praised the system's rich functionality, user-friendly interface, user-friendly design, system stability, and reliability.
