High-precision high-safety novel water body heating composite control system

Abstract

The invention discloses a high-precision high-safety novel water body heating composite control system which comprises a phase-shifting power regulating module, a display module, a temperature acquisition module, a water-leaving power-off module, a silicon controlled rectifier temperature detection module and a CPU. The system has the beneficial effects of high safety: through a multiple protection mechanism, when high temperature occurs or water temperature is out of control, a relay protection circuit can forcibly close output, so that high-temperature danger of the water body can be effectively avoided; the circuit is arranged through soft starting, so that current impact caused when a heating body is started can be reduced, a control module and a driving module are isolated through theaccess of an optical coupler, the separation of strong current and weak current is realized, and the whole system is safer; high temperature control precision: through the PID algorithm and power regulation output, the water body can be stably heated, and the water body is always kept within the set target temperature range; and good intelligence: through the water-leaving power-off module, whenthe heating body accidentally leaves the water surface, heating is intelligent stopped, and the circuit and the heating body are protected.

Description

technical field [0001] The invention relates to the field of water body heating, in particular to a high-precision and high-safety novel composite control system for water body heating. Background technique [0002] At present, large-scale water body systems, such as swimming pools, especially in winter, need to heat the pool water in order to prolong the use time of the pool and maintain a suitable temperature of the pool water, so the swimming pool is a large energy-consuming household; Heating is done by heating rods, but the quality of the current heating rods is relatively low and the temperature control of the current heating rods is not accurate. It is easy to get out of control and overheat the fish with catastrophic consequences and burn people. Contents of the invention [0003] The object of the present invention is to provide a high-precision and high-safety new composite control system for water body heating in order to solve the above problems. [0004] To a...
