The development trend of thermostats in 2022

Thermostats belong to the forefront of information technology, especially thermostats are widely used in industrial and agricultural production, scientific research and life and other fields, and the number is increasing day by day. In the past 100 years, thermostats are developing from analog to digital, from integrated to intelligent and networked.

1 Product classification of thermostats

1.1 Analog, integrated temperature controller

Analog temperature controllers mainly include temperature control switches, programmable temperature controllers, and some enhanced integrated temperature controllers also include A/D converters and cured programs, which are similar to smart thermostats. place. But it is a self-contained system, and it is not controlled by the microprocessor when working, which is the main difference between the two.

1.2 Smart Thermostat

Smart thermostats (also known as digital thermostats) were introduced in the mid-1990s. It is the crystallization of microelectronic technology, computer technology and automatic test technology (ATE). At present, a variety of intelligent thermostat series products have been developed. Smart thermostats contain temperature sensors, A/D converters, signal processors, memory (or registers) and interface circuits. Some products also have multiplexers, *controllers (cpu), random access memory (RAM) and read only memory (ROM). The characteristics of the intelligent thermostat are that it can output temperature data and related temperature control quantities, and adapt to various thermostat controllers (MCU); and it realizes the test control function through software on the basis of hardware, and its intelligent The degree of integration also depends on the level of software development.

2 New trends in the development of intelligent thermostats

After entering the 21st century, intelligent thermostats are moving towards high-precision, multi-function, bus standardization, high reliability and safety, developing virtual thermostats and network thermostats, and developing single-chip temperature measurement and temperature control systems. direction is developing rapidly.

2.1 Improve temperature measurement accuracy and resolution

2.2 Add test function

2.3 Standardization and normalization of bus technology

2.5 Virtual Thermostat and Network Thermostat

(1) Virtual thermostat

(2) Network temperature thermostat

2.6 Monolithic temperature measurement control system

At present, in China's thermostat market, Xiamen ETOP is an ODM/OEM one-stop service manufacturing factory, with leading technology and advanced equipment in the industry, which can bring satisfactory customized solutions to regions in the world that need thermostats.
