【正文】 he occasional noise interference, and will not affect the normal working temperature control system. ACPI (Advanced Configuration And Power Interface, that is, Advanced Configuration and Power Interface) regulate the temperature control system. This system is perfect overheat protection function can be used to monitor notebook puters and servers CPU and the main circuit temperature. Microprocessor maximum tolerable temperature requirements for the work of TH, desktop puters typically 75 176。 C, highend notebook puters dedicated CPU up to 100 176。 C. Once the CPU or main circuit set by the temperature in excess of the upper and lower limit, the INTgenerated immediately interrupted, and through the power supply controller is a signal to quickly play a main power shutdown protection. In addition, when the temperature exceeds the limits of CPU temperature, superserious can also directly shutdown the main power, and the end hardware but also through independent shutdown circuit to cut off the main power to prevent the main power supply is out of control. The triple security protection measures have bee an international design temperature control system on the new concept. To prevent human electrostatic discharge (ESD) damage chips. Some smart temperature controller has also increased the ESD protection circuit normally can withstand 1000 to 4000 V electrostatic discharge voltage. Usually the body is equivalent to 100 PF capacitance and K ohm resistor in series from the circuit model, when human discharge, TCN75 intelligent temperature sensorserial interface, interrupt / parator signal output and input addresses are can withstand 1,000 V voltage electrostatic discharges. E. Virtual temperature controllers, and work Temperature Controller (1) Virtual temperature controller Virtual temperature controller is based on the temperature controller hardware and puter platforms, and the software was developed. Software can be used to plete the 英文文獻(xiàn) （原文） 15 calibration and temperature controller calibration, in order to achieve the best performance. Recently, the United States B amp。 K Corporation has developed a set of softwarebased virtual TEDS sensor, its main characteristic is that each sensor has the only product with a serial number and floppy disks, diskettes to store the calibration of the sensor relevant data. Use, the sensor data acquisition through access to a puter, first of all puter input from the sensor array of products, from floppy diskettes to read out the relevant data, and then automatically checks the sensor, the sensor read parameters, sensors installed and records work. (2) Network Temperature Controller The Network temperature controller includes digital sensor, work interface and a new generation of intelligent processing unit temperature controller. It will be the first digital sensors measured temperature converted into digital and then gave microcontrollers for data processing. Finally, the measurement results to the transmission work, in order to achieve the sensor, the sensor and actuator between sensors and data exchange between the system and the sharing of resources and the replacement sensor calibration and the need for calibration can be achieved, namely plug, and (Plug amp。 Play), This will greatly facilitate the users. F. The temperature controllerchip temperature control system The Monolithic System (System on Chip) is a 21st century hightech products. It is onchip integration of a system or subsystems, the integration will be as high as 108 to 109 ponents / tablet, which will IC industry and IC applications epochmaking progress. Semiconductor Industry Association (SIA) on systemonchip integration of the forecast shown in Table 1. At present, some famous international IC manufacturers have already started to develop singlechip temperature measurement system。 I believe that in the near future be available. However, the temperature controller development to a large extent depends largely on the degree of development of temperature sensors. The sensor is the forefront of cuttingedge information technology products。 in particular the temperature sensors are widely used in industrial and agricultural production, scientific research, and living areas, the highest number of sensors in the first place. It is undeniable that the sensor in its domestic 英文文獻(xiàn) （原文） 16 products, product quality and its application in the field of the sensor with foreign products still lags significantly behind. However, we should also see domestic sensor to enter the international market momentum and determination. Therefore, the only fully grasp the sensor technology, and on this basis to improve their accuracy from the expansion of its functions, as well as refine and improve its reliability and safety, the development of virtual sensors and sensor works developed singlechip temperature measurement system contour science and technology, and be able to hold the temperature measurement and control technology development direction. 英文文獻(xiàn) （譯文） 1 AT89s52 單片機 at89s52 是美國 ATMEL 公司生產(chǎn)的低電壓，高性能 CMOS8 位單片機，片內(nèi)含4Kbytes 的快速可擦寫的只讀程序存儲器（ PEROM）和 128bytes 的隨機存取數(shù)據(jù)存儲器（ RAM），器件采用 ATMEL公司的高密度、非易失性存儲技術(shù)生產(chǎn)，兼容標(biāo)準(zhǔn)MCS51 產(chǎn)品指令系統(tǒng)，片內(nèi)置通用 8 位中央處理器（ CPU）和 flish 存儲單元，功能強大 at89s52 單片機可為您提供許多高性價比的應(yīng)用場合，可靈活應(yīng)用于各種控制領(lǐng)域。 1. 主要性能參數(shù) ?與 MCS51 產(chǎn)品指令系統(tǒng)完全兼容 ? 4K 字節(jié)可重復(fù)寫 flash閃速存儲器 ?128*8 字節(jié)內(nèi)部 RAM ?32 個可編程 I/O 口 ? 2 個 16 位定時／計數(shù)器 ?6 個中斷源 ?可編程串行 UART通道 ?低功耗空閑和掉電模式 英文文獻(xiàn) （譯文） 2 AT89S52 提供以下標(biāo)準(zhǔn)功能： 4K 字節(jié) flish閃速存儲器， 128 字節(jié)內(nèi)部 RAM， 32個 I/O 口線，兩個 16 位定時／計數(shù)器，一個 5 向量兩級中斷結(jié)構(gòu)，一個全雙工串行通信口，片內(nèi)振蕩器及時鐘電路。同時， at89s52 可降至 0HZ的靜態(tài)邏輯操作，并支持兩種軟件可選的節(jié)電工作模式?？臻e方式停止 CPU的工作，但允許 RAM，定時／計數(shù)器，串行通信口及中斷系統(tǒng)繼續(xù)工作。掉電方式保存 RAM 中的內(nèi)容，但振蕩器停止工作并禁止其它所有部件工作直到下一個硬件復(fù)
