Abstract

The invention discloses a heat pump Internet of Things system based on PLC control, including a processing terminal and a plurality of heat pump devices. The heat pump devices include a PLC controller, a temperature sensor, a power adjustment module and a wireless communication module. The PLC controller communicates through wireless The module is communicatively connected to the processing terminal; the wireless communication module includes an MCU chip, a WIFI communication module and a serial port protocol conversion unit, the MCU chip communicates with the PLC controller through the serial port protocol conversion unit, and the MCU chip communicates through the WIFI communication module. The group is communicatively connected to the processing terminal. The invention realizes the data format conversion function between the WIFI communication module and the PLC controller through the MCU chip, so as to realize the communication connection function between the PLC controller and the WIFI communication module, and finally realizes the heat pump equipment controlled by the PLC controller. IoT networking function, fast communication speed and wide effective communication range.

Description

technical field [0001] The invention relates to the technical field of heat pump systems, and more specifically relates to a heat pump Internet of Things communication system. Background technique [0002] Heat pump is a high-efficiency energy-saving device that makes full use of low-grade heat energy. Heat pumps are used in a wide range of places. Among them, applying heat pumps to swimming pools to ensure that the swimming pools are in a constant temperature state is a relatively common application. [0003] In the prior art, the heat pump equipment has a relatively fixed effective range, that is, the heat pump equipment can only control the temperature within a certain range according to the temperature data within the range, so when it is necessary to maintain a constant temperature for a wide range of applications When controlling, it is necessary to use multiple heat pump devices to realize the temperature control function. However, the existing heat pump equipment ma...
