摘　　要：采用负温度系数热敏电阻器(NTC)设计的超温报警电路是针对机房室内温度的监控,保证机房内的计算机在规定温度内正常工作。如果机房室内温度超出规定温度时便立即报警,提醒工作人员作降温处理并维护设备,同时记录报警次数。此设计简单、成本低廉、检测准确,是一个实用性很强的固定温度控制系统。Based on the computer-room indoor temperature, this paper adopts NTC to design a simple over-temperature alarm circuit to ensure work in the computer room within the specified temperature. If the room temperature exceeds the specified temperature, the alarm rings immediately to remind staff to perform the cooling treatment and maintenance of equipment and to keep a record of the alarm number. This practical temperature control system, is simple in design, low in cost and accurate in detection.
