1.1 Introduction 
 The system runs on WINDOWS98 and above systems, human-computer interaction, that is, learning that is used, the software program using object-oriented design methods, modular management technology, multitasking, advanced serial communication technology, integrated system control and data management, compatibility, and ease of maintenance, the computer interface board to overcome the drawbacks of pick slot, with a wide range of adaptability, the use of scientific and effective algorithm, data accuracy, system reliability. 
 The microcomputer automatic calorimeter mainly used in coal, petroleum, chemical, food, timber, explosives and other combustible Determination of heat. 
 1.2 Key performance indicators 
 1, the heat capacity of about 10500J / K 
 2, the external water tube capacity of about 51L 
 3, the cylinder capacity of about 2.1L of water 
 4, the ignition voltage of 20V 
 5, ignition time process control 
 6, the measurement accuracy better than the national standard 
 7, the temperature resolution of 0.0001 degrees 
 8, 5-40 degrees with the environment 
 9, power supply 220V ± 10% 
 1.3 Instrument characteristics 
 1, computer calorimeter maintain the full functionality of computer system, run common software for other transactions. At the same time start the calorimeter standard quantitative measurement system can automatically be equivalent thermal analyzer system to measure heat. Input sulfur, water, hydrogen and other data, and print out can be converted Calorific, high heat, heat the status of such data. 
 2 barrel calorimeter device electric mixer with paddle sheet, outer tube stirred mixing with electric submersible pumps, so that mixing is more uniform and more convenient. Instruments used cotton thread fuse type ignition. 
 3, computer WINDOWS98 calorimeter operating in and above the operating system, the whole process of Chinese characters suggest that human-computer interaction, that is, learning that is used, according to the prompts to complete the test. 
 1.4 The main functions of the system 
 System can automatically calibrate the system heat capacity of heat and material to the determination of the calibration of the system heat capacity selection method using multi-dimensional, real-time flexibility. Heat of the measurement process material and data processing were computer automatically. According to sulfur, water, hydrogen content, automatic conversion out of the cartridge heat, high heat, heat and received the status of the base heat. Measurement using digital image 2 tips and methods, visual image. 
 The main function of the system: 
 (1) data: Calorific refers to the data processing, according to sulfur, water, hydrogen content in a variety of base conversion, the results of its analysis of the data can query, save, print, and so on. 
 (2) Print: refers to the current heat and heat capacity of the test result data of the print output. 
 (3) Test: refers to the system, ignition, mixing, drainage, water injection testing. 
 (4) Tools: refers to the computer serial communication port selection, heat, coke shows that the calorific value of additives, hot point parameters, heat capacity changes, the adjustment of injection time and detection unit name registration. 
 (5) Description: refers to the technical characteristics of the system, system introduction, instructions and introduction of heat essentials. 
 (6) Wizard: refers to the common failures of the system. 
 (7) Exit: to turn off the computer calorimeter system. 
 1.5 laboratory 
 1, the laboratory should be located in a separate room, not in the same room for other pilot projects. 
 2, room temperature should be kept constant, each measurement should not exceed 1 degree temperature change, usually at room temperature should not exceed the range of 5-40 degrees is appropriate. 
 3, indoor air should be no strong convection, the experiment should be avoided in open windows and doors. 
 4, the best laboratory north to avoid the sunlight, or heat meter should be free from direct sunlight.
