Solar hot water automatic control system based on Internet of Things module

Abstract

The invention discloses a solar hot water automatic control system based on an Internet of Things module. The solar hot water automatic control system comprises the Internet of Things module. The Internet of Things module is connected with a detection module, is in signal connection with a mobile app and is connected with an intermediate relay. The output end of the intermediate relay is connectedwith an alternating current contactor, and the alternating current contactor is in control connection with a circulating pump. The solar hot water automatic control system is reasonable in design. The application of the Internet of Things module simplifies a power supply line of a heating system, so that future maintenance and troubleshooting work are much easier than before. Through the connection with the mobile app, state queries and temperature control are facilitated, all temperature data can be viewed at any time, and the circulating pump can be manually controlled to start or stop at any time. The solar hot water automatic control system has real-time performance and high efficiency.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a solar water heating automatic control system based on an Internet of Things module. Background technique [0002] At present, the heating facilities of many colleges and universities use solar water heating system for heating, but this heating system still has the following problems: due to the technical problems of the equipment used, the temperature acquisition signal has a large degree of distortion, resulting in the temperature difference cycle. The driving delay and error are large. Moreover, the heating facilities do not use wireless control technology, and all signal transmission depends on the transmission of lines, resulting in too many and complicated lines in the system. In addition, when the temperature of the system is too low, not only will the system fail to operate normally, but in severe cases, the heat collecting tube will be damaged by freezing. I...
