e / land in the value (car value), weighbridges and other fitted forcesensitive sensors and microputercontrolled intelligent weighing instruments bee intelligent digital electrical and mechanical balance (or the mechanical and electrical dualuse scales), to improve the mechanical balance of the measurement accuracy, with low cost, high reliability, simple installation and so on, without prejudice to the original mechanical scales to any transmission bearing structure. There are peeled, set to zero, the cumulative number of times, the cumulative weight (cumulative amount of valuationbased), autozeroing, autotracking and other functions. Weighing data can be directly printed or transmitted via puter works, industrial processes can improv e the level of scale and product quality, trade clearing with the scale can improve the credibility of incalculable social and economic benefits. Electronic Scale is basically a sensor, amplifier circuit, A / D conversion circuit, microcontroller control of display parts, switch matrix circuit, the keyboard circuit and power circuit. Weight sensor signals are converted to a corresponding electrical signal, after amplified into the A / D converted into pulses weight, through the SCM under the control of the analog voltage signals into digital. The digital conversion by the SCM program in line with the actual weight of the value of sending the number of display windows. MCU at the same time the keyboard and switch matrix for monitoring. According to the input parameter values, the program handled accordingly. Power circuit to provide the various parts of the operating voltage. Microprocessors such as 8050, HD404418F, 8031, etc. CPU. Highly versatile motherboard, different values of range and subdegree scales, just adjust the jumpers on the motherboard and the DIP switch can be achieved, the only difference is that the sensor used with a rated carrying capacity Sensor is a physical device or biological organ that can detect and feel the outside of the signal, physical condition (such as light, heat, humidity) or chemical position (such as smoke), and Discovery of information to other devices or organs. Definition of sensor National standard GB766587 sensor is defined as: can feel the requirements are measured and converted in accordance with the laws of certain signal device or devices available, usually posed of sensitive ponents and conversion devices. Sensor is a detection device, can feel the information being measured, and can detect sense of information, according to certain laws of transformation into electrical signals, or other forms of information required for output to meet the information transmission, processing, storage, display, recording and control requirements. It is the automatic detection and control of the primary link. The role of sensor People in order to obtain information from the outside world must help of sense organs. And rely on people39。 s own sense organs, the study of natural phenomena and laws, and production activities in their functions on far enough. To meet this situation, we need sensors. It can be said sensor is an extension of human senses, also known as electronic features. The arrival of the new technological revolution, the world entered the information age. In the course of the use of information, we must first resolve is to obtain accurate and reliable information, and sensors is to obtain information in the field of natural and production of the main ways and means. In modern industrial production, especially automated production process, the use of various sensors to monitor and control the various parameters of the production process, so that devices work best in the normal state or condition, and to achieve the best quality products. Therefore we can say, without a large number of good sensors, modern production base will be lost. In the basic science research, a more prominent position sensor. The development of modern science and technology into many new areas: for example, thousands of light years to observe the macro level of the vast universe, to observe microscopically small particles cm the world, vertical, to observe the evolution over hundreds of years of celestial bodies , a short response to the s m。
