Automatic instrumentation debugging of metallurgical plant
Automatic instrumentation debugging is an important part of automation system debugging. It is the foundation for the whole process to ensure the stable and reliable operation of the entire automated system. The content of automatic instrumentation debugging includes system detection, local debugging, and site debugging.
System inspection is the first step in debugging instrument automation. The purpose is to find out whether the system is complete and the parameters are reasonable according to the program. The debugging includes system structure, system selection and configuration, program design and communication interface design. After system detection, the local debugging is proceeded.
The local debugging is to ensure that each program module is correct and can boot. This step needs to check all software parameters, enter the starting parameter menu, adjust the parameter to meet the system requirements and then debug the modules one by one. After the local debugging is completed and the system is tested, the entire system is connected and debugged.
The debugging of the site includes several parts, such as system booting, parameter setting, open loop test, closed loop test, system running test, protection function test and so on. It is the most important step in the debug of automation instrumentation. When the detection is completed, the system can be formally started.
First of all, the system booting means that the system automatically starts up and enters the running state. Secondly, the system needs to be configured and the parameter needs to be set according to the program. Thirdly, the open loop test needs to be performed to ensure that the operation of each element and signal is correct. The closed-loop test is then performed to check the signal range and signal accuracy. Finally, the system running test is performed and the protection function test is performed to check whether the protection function can be compatible with the system. After the debugging is completed, the automation equipment is debugged.
In the instrument automation debugging, the debugging personnel must pay attention to the safety of the system, adjust the parameters correctly, and avoid misoperation. In the test process, attention should be paid to the stability of the system, and analyzing and solving the debugging problems timely and correctly. At the same time, do the data collection, so as to further adjust the parameters and make the system more stable.
Auto instrumentation debugging is a complex process. It requires the system integrator to pay attention to the mutual influence between various parameters and the systems various conditions of operation. It needs to be tested and adjusted step by step, and the debug personnel must have a deep understanding of the technical principle of automation system and debugging technology, so as to ensure the stability and reliability of the system.
