The temperature Monitor in these fields of the Boiler heating temperature is to play the role of controlling the Boiler system temperature. At present, thermocouple or thermistor as sensor is used in terms of detection the temperature generally. The dedicated wire temperature compensation usually used between the sensor and the Instrumentation. Computer as the PC、 Board and Intelligent Instrumentation is used to achieve Function of the temperature Monitor in this design to view the temperature anywhere in time. In order to improve the capability of the boiler temperature control system so that display and control are implemented in one computer, a simple and low cost temperature monitoring system of the boiler is obtained. The general industry control computer and basic IC block are applied in the hardware of the temperature control system. The domestic configuration software King View is used in the system, King views command language and advantaged control algorithms are designed to temperature control capacity and the best working state. The boiler temperature control system has strong dependability, low cost, convenient maintenance, good compatible capability and running effect. The boiler temperature control system, which is inexpensive and has strong application and stabilization, is applicable to establishing a small boiler temperature control system, and especially
