Abstract

The invention discloses a multi-way temperature detecting controller, which is characterized in that the controller includes 4-8 one-wire temperature probes, a set of controlled heating units and an MCU control center; the temperature probes are connected with the heating units and geometrically distributed in a heating space to measure the peripheral temperature; the selected temperature probes are connected with the MCU control center by connecting wires and send measured temperature to the MCU control center, then the MCU control center compares the received temperature value with a stated reference temperature value, if the received temperature value is lower than the reference temperature value, the heating units are controlled for heating so as to maintain a point at a temperature constant state. The controller can realize the control precision that the target temperature fluctuates at a range of 1.5 DEG C to minus 1.5 DEG C.

Description

【Technical field】 [0001] The invention relates to temperature detection and control technology, in particular to a multi-channel temperature detection controller with a temperature control accuracy within + / - 1.5 degrees Celsius. 【Background technique】 [0002] With air as the heat-conducting medium and single-chip microcomputer as the control core, the controller of single-point temperature probe + heating device has appeared for a long time. There are many models and powerful functions, and some controllers have complex detection-control-heating modes. But most of these existing temperature controllers still haven't solved the important problem of precise constant temperature, that is, the problem of temperature control accuracy. The reason is that the key point is that it is incomplete and unreliable to use single-point temperature detection and control as a means of constant temperature, and it ignores the mutual influence of temperatures between various temperature poi...
