1. Program Background

Although Kiln in our country has a great leap in the digestion and absorption based on foreign advanced technology, it still remain in the level of the PID control mode dispersion control and PLC logic control, though it can meet the needs of normal production on the way, the aftermarket services are difficult to meet the satisfaction of customers: Firstly, problems of the kiln production process is difficult to feedback to the furnace manufacturer timely and accurately, which affects the normal production order; second, furnace manufacturer cannot receive feedback timely and accurately, and space constraints increase the impact of the furnace manufacturer's service level. Thus, it is necessary for the rapid development of network technology to find out a new control method to solve these problems, based on this, we propose a network kiln control technology to this new research topics.

2. Achieve purpose

 (1) Change the current situation of domestic furnace, provide strong technical support for the grade, brand.

 (2) Provide users with fast, high quality and efficient after-sales service, to solve the problem on the user device the first time, to minimize the loss of customers.

 (3) To provide the most effective technical support for the user's normal production.

(4) Minimize service costs.

3. Feasibility Analysis

The feasibility of this system we make the following analysis:

(A) System Configuration

The computer control system uses PⅡ host, high-capacity hard drives and memory, international standard communication ports, data reading and processing of superior IPC and faster operation. On the software side: Provides user multi-level sub-menu under WINDOWS interface to modify the function, which greatly improve user operations in the production process.

(B) Technical support

Network application technology is mature and kiln control technology was successfully applied, technology guarantees the successful implementation of the system.

(C) Economy

Through the implementation of this system, we can provide users with advanced, comprehensive, reliable technical services at the same furnace, making it run more efficiently and reduce management costs. Meet the technical requirements and reliability, making computer peripherals research system configuration by market price and the best selection; through cooperative development approach to reducing software development cycles, cost and risk.

(D) The setting by licensed rights to prohibit non-authorized people access, ensure the system security, confidentiality.

4. System Planning

According to the status of kiln control technology and associated control equipment production, the control system implement step from lower to higher three-step.

(A) Primary

Computer and PID regulator constitute interactive kiln computer control system, and through INTEMET.

(B) Intermediate

Realize remote monitoring on primary basis.

(C) Advanced

While in remote monitoring, soft fault kiln associated control equipment to implement remote diagnosis.

Technical support:

1. Relevant kiln control software has been successfully developed;

2. The application of network technology is quite mature;

3. Related furnace control equipment development work has been carried out (for advanced control mode).

5. System Principles Introduction

A. System Functions

1. The realization of the furnace working process real-time monitoring.

2. The detecting for each furnace set point temperature (thermocouple).

3. The furnace temperature to visually articulate, and reflects of the gap between the actual temperature and the set temperature (in a different color curve identification).

4. Timely monitoring of all control valves.

5. Timely temperature alarm.

6. The reporting and graphical output capabilities.

7. View historical data and print.

8.  Control devices for monitor or control.

9. The work interface provides convenient interactive functions.

10. The user can be provided multiple levels of menu modification.

11. The authorized person can remote monitoring or control by INTERNET.

B. System software features

Kiln-site control equipment via the relevant module parameters transferred to the main control room, information input for analysis of on-site computer control system, information after treatment, combining conventional PID regulator to jointly implement the monitoring function of each device.

General Manager's Office of the user can monitor the computer system in the main control room and emergency treatment failure through LAN.

OTSK Technical Service Center (authorized person) monitor the main control room computer， through internet control monitoring the computer control system. Implement its system maintenance functions in time, when the furnace operational failure, system software can perform troubleshooting and provide furnace maintenance program in the first time.
