Abstract


Now it has been recognized as a country or region's per capita annual consumption of plastics and plastics industry in the national economy is a reflection of the position occupied by industrial development and an important sign of progress. This article mainly injection molding machine temperature detection system is studied and implemented. Firstly, the overall scheme of the hardware design. Selected thermocouple for temperature measurement, while using AD590 cold junction temperature compensation to ensure that the system temperature measurement accuracy. In order to improve the accuracy of sampling and enhancing the use of the system, the choice of a high-precision multi-channel AD7656 chip as the input signal sampling chip to facilitate the expansion of the system; taking into account the actual needs of industrial production, foreign expansion RAM circuit design , using the storage capacity of the DS1270 chip 2M, according to the protocol set stored in the real time recording the detected data, and finally, in order to enhance the friendly man-machine interface, a liquid crystal display panel using WQ_VGA driver board, and the hardware on the design of appropriate interfaces for subsequent software designed to provide a foundation. Most of the topics second temperature detection system PC software is designed and implemented. PC software program includes DSP2812-based programming and program development based on the display terminal two parts. Using the DSP simulation software - CCS as a platform for application development, programming DSP2812 achieve the basic function, and the corresponding module (SCI, external expansion RAM, etc.) conducted a program designed to achieve a normal and reliable between the various modules communications; according WQ_VGA data format specified on the preparation of a variety of control commands function and call these functions to achieve a variety of display functions, the system greatly enhanced the friendly human-computer interaction. Since the system has a universal characteristic of signal detection, so in order to increase the use of the system, this method of digital filtering conducted research and analysis. A brief description of the conventional digital filtering methods, and characteristics of the system used for the gross error removed, go to extreme average filter, least squares filtering several ways, and the effectiveness of various methods of experimental verification. This topic is designed temperature detection system with high reliability, real-time data is good, powerful, strong and friendly man-machine interface and many other features. In addition, although the system is in the design of injection molding machine when the temperature detected as application background, but the implemented system can be applied to many areas of signal detection, with a very wide scope of use.
