What does PC development mean?

Host computer development refers to the development of computer programs on the host computer (also called a control computer or operator terminal). The upper computer communicates with the lower computer (usually an embedded system or PLC) through communication methods such as serial port or network, and controls and monitors the lower computer. PC development is usually widely used in industrial automation, instrumentation, medical equipment and other fields.

The main purpose of developing the upper computer is to realize the functions of data collection, control and monitoring of the lower computer. Specifically, the development of the host computer includes the following aspects:

1. Communication protocol design: Communication needs to be carried out between the host computer and the lower computer, so the communication protocol needs to be designed, including data format, data Transmission rate, verification method, etc. Communication protocols should be designed with stability and reliability in mind to ensure accurate transmission of data.
2. Data processing: The upper computer needs to receive data from the lower computer and perform data processing, such as data filtering, data conversion, etc. Data processing can include data display, storage, analysis and alarm functions.
3. Human-machine interface design: The host computer needs to provide a visual human-machine interface so that the operator can easily control and monitor. Human-computer interface can include text, graphics, animation and other forms, taking into account ease of use and user experience.
4. Real-time control: The upper computer needs to send control signals to the lower computer according to the instructions input by the operator or the preset program to achieve real-time control of the lower computer. Real-time control needs to consider response speed and accuracy to ensure system stability and safety.
5. Fault diagnosis: The host computer needs to have fault diagnosis function. When a fault occurs, it can detect and prompt the operator in time. Fault diagnosis can include functions such as data analysis, anomaly detection, and fault location.

When developing a host computer, you usually need to choose appropriate development tools and programming languages, such as C, Java, etc. At the same time, you also need to understand relevant communication protocols and interface standards, such as Modbus, OPC, etc. In addition, for specific application scenarios, factors such as system reliability and stability also need to be considered.

In the field of industrial automation, host computer development is usually widely used in the following aspects:

1. Process control: In the production line or industrial manufacturing process, the host computer needs to monitor and control various parameters during the production process to ensure the stability of the production process and product quality.
2. Data collection and processing: The upper computer needs to collect data from the lower computer and perform data processing and analysis. Through data processing and analysis, various information and indicators in the production process can be obtained.
3. Fault detection and diagnosis: The upper computer can detect and diagnose faults in time by monitoring and analyzing data from the lower computer. Fault detection and diagnosis can improve production efficiency and equipment service life.
4. Human-machine interface design: In the field of industrial automation, the host computer needs to provide a visual human-machine interface so that the operator can easily control and monitor. Human-machine interface can improve operational efficiency and user experience.

In short, the development of the upper computer is a very important link in the field of industrial automation. It can control and monitor the lower computer and improve production efficiency and management level. At the same time, host computer development also needs to consider factors such as system stability, reliability, and ease of use to meet the needs of different application scenarios.
