Controller used for off-peak electricity heat-accumulation heating system

Abstract

The invention relates to a controller of a heating system, and discloses a controller used for an off-peak electricity heat-accumulation heating system. The controller comprises a singlechip microcomputer on which three external control interfaces are further arranged; the three external control interfaces respectively are an interface 1, an interface 2 and an interface 40, wherein the interface 2 is connected with a fan drive circuit connected with an external fan; the interface 1 is connected with a relay drive circuit connected with a relay, the relay is connected with a principal line and is used for heating a heating pipe, and the interface 40 is connected with a temperature measurement circuit. According to the controller, the heating time and heating duration can be automatically controlled by the single-chip microcomputer, the temperature control is carried out by the temperature measurement circuit, and the scald on a user can be prevented, so that the controller is an ideal controller used for the off-peak electricity heat-accumulation heating system.

Description

technical field [0001] The invention relates to a controller for a heating system, in particular to a controller for a heating system with low-valley electric heat storage. Background technique [0002] Low-valley electric heat storage is a new type of heating and heating method, which stores the thermal energy generated by low-valley electricity during the low-peak period of electricity consumption for use during the day, which greatly saves operating costs and It reduces the burden on the power grid and is gradually recognized and used by people. When the existing low-valley electric heating system is in use, its functionality cannot meet people's actual needs, and the control of its various functions is mainly through manual control or fixed control, resulting in the inability to realize various automatic functions. For example, the existing The current low-valley electricity heat storage device is only suitable for low-valley electricity use, and requires a fixed and fi...

Problems solved by technology

When the existing low-valley electric heating system is in use, its functionality cannot meet people's actual needs, and the control of its various functions is mainly through manual control or fixed control, resulting in the inability to realize various automatic functions. For example, the existing The current low-valley electricity heat storage device is only suitable for low-valley electricity use, and requires a fixed and fixed duration for the low-valley electricity time period. The existing control device cannot adjust the heating time period; the existing low-valley electricity heat storage device control system cannot control The "heating time" and "heating temperature" are limited. If the temperature of the shell exceeds the safe range, it is easy to burn the user; when the temperature of the heat storage brick drops to a low temperature, the heat dissipation rate cannot be improved through automatic control, and natural convection alone cannot achieve to heat dissipation rate requirements
