The whole course intelligent monitoring temperature control switch is a new generation of digital temperature control switches which use world's leading single-coupling theory and fuzzy control technology for the first time by the Shanghai Voicetune Information Technology Co., Ltd. The company owns all intellectual property rights including the heating line, control software and the circuit board production. This type of product has advantages like easy installation, saving time and electric, highly secure, highly intelligent. It can effectively prevent fire accidents caused by folding; wrinkling or wire broken while supplying electric. And it is safe and comfortable to use. Using single-wire control can reduce the quantity of wire by half, which significantly reduces costs. It can save 40% electric energy to users by using the whole course intelligent monitoring. Therefore, it has great economic and social benefits.

Core Technology:
1. Combine the temperature-controlled wire and heating wire and developed a new temperature-controlled heating wire for heating and temperature controlling, which greatly reduce the cost of the current two-lane structure.
2. Using LED display to track the whole course of temperature, showing the entire performance index, the status of whole course tracking increases convenience and practicality.
3. The coupling principle is the first time using to measure the strong electric current on the heat wire, thereby to control the power of strong electric and to maintain constant temperature through converting weak voltage to temperature.
4. The real-time detection to the voltage and current on heating wires can effectively prevent insecurity caused by sudden change of voltage and current and greatly increases security. Its secure features are as follows:
a) high-voltage power-off protection b) high-temperature power-off protection c) protection to the sudden change of voltage d) Current overload protection e) low-temperature protection f) protection to circuit matches
5. Have functions of regularly turn on and off, both convenient and power saving.
