6Users can create and modify multiple automatic heating programs, driving programs, parking programs, and emergency shutdown programs;

7Users can easily set and modify process parameters and alarm limits.

3.3 Chain protection system

The automatic control system adopts foreign design and manufacturing standards, and the entire system has multi-level safety protection design and configuration, reaching the level of introduction.

Due to the fact that the system generally operates under flammable and explosive materials, its safety and reliability requirements are *. The self-control system adopts multiple strict safety control logics for upward traffic;IBXContinuously receiving heartbeat pulses from the computer, if for any reason the computer malfunctions and the heartbeat stops, when the temperature or pressure reaches a high limit（Demand）At this time, the computer will issue instructions to automatically activate the relevant protection logic; Each reaction unit is equipped with a safety relief valve to prevent system overpressure; Dynamically monitor the process and ensure that the relevant process parameters reach the minimum limit（Lo）Or high limit（Hi）At this time, the system generates an audible and visual alarm to remind the operator to handle it in advance.

3.4 Automatic program heating

We adopt a function automatic program heating mode, Meet the practical needs of various applications, And it can significantly improve the level of automation and unmanned capability: each program heating section can be used for automatic heating or automatic cooling. During the multi-stage automatic heating process, manual intervention such as stopping and holding can be performed, During the multi-stage automatic heating process, automatic cooling can be set. It can save commonly used heating and cooling configurations for easy import of customized configurations. Conveniently display the current running time, remaining time, gradient start time, gradient end time, hold start time, hold end time, etc. during the automatic heating process.

3.5 Automatic reporting program

The instrument adopts an automatic reporting program with function *, Meet the practical needs of various applications, And it can significantly improve data processing capabilities and automation level: provide multiple types of report templates, and follow the pre madeEXCELStandardized templates can automatically generate multiple reports simultaneously, allowing for real-time dynamic reading of real-time data, historical data, and other relational databases. Reports can be triggered at preset times, at intervals, and automatically saved based on events. Reports can be triggered at preset intervals, at time intervals, and automatically printed based on events. The report file name can be automatically generated according to pre-set rules.
