[0003] Chinese patent (patent application number: 200710302530.1, invention name: real-time intelligent thermostat) discloses such a thermostat, which includes a microcontroller module connected to the input terminal of the microcontroller module for sensing A temperature detection module for temperature, a power supply circuit for converting alternating current into direct current to supply power for the microcontroller module, and a display module connected to an output end of the control module, which can be implemented in a temperature-controlled Under the premise, the current display control of several groups can be realized at the same time. If the current overload, phase loss or three-phase imbalance occurs, it can be detected in time, and the fault can be eliminated in time to protect the unit. In addition, the adoption of this technical solution can also Real-time monitoring control and centralized control of the thermostat can be realized, but this technical solution still has such a disadvantage that it is difficult for the thermostat to interface with different types of LCD screens from multiple manufacturers, and additional Additional software programming is performed on the programmable device part of the smart thermostat, which increases the difficulty of docking and increases the workload of developers and designers

The invention discloses a temperature control device and a temperature control system. The temperature control device provided by the invention is an ASIC (Application Specific Integrated Circuit) integrated with functions of a temperature controller. The temperature control device can be flexibly combined with external liquid crystal display modules with different models so as to finish the design of the overall temperature controller without additionally carrying out software programming on a programmable device part of the temperature controller, wherein the external liquid crystal display modules with different models are manufactured by different factories, so that the difficulty in docking is reduced, and the amount of work of development and design workers is also reduced.
Description
Technical field [0001] The present invention relates to the field of ASIC (Application Specific Integrated Circuit, application specific integrated circuit), in particular, to a temperature control device and system, wherein the temperature control device is an ASIC application specific integrated circuit integrated with a temperature controller function. Background technique [0002] Temperature control technology is to artificially control the temperature of an object or corresponding space at the required temperature in some way. Smart thermostats are widely used in large supermarkets, industrial refrigerators, freezers and other occasions. They mainly use single-chip microcomputer as the core to realize automatic temperature control. The control circuits of existing smart thermostats usually include single-chip microcomputers and power circuits for supplying power to the single-chip microcomputers. A temperature sensor set on the corresponding device and a display for tempera...
