Remote temperature controller for transmitting computer temperature control information by using power line carrier

Abstract

The invention discloses a remote temperature controller for transmitting computer temperature control information by using a power line carrier, which consists of a transmitting system and a receiving system. The transmission system is connected with the receiving system via a power grid. The transmitting system consists of a central machine temperature presetting programmer, a duplex modem I, a high voltage isolator I, a high voltage isolator II, a site return information processor and a digital display I; and the receiving system consists of a central machine temperature control programmer,an adapter, a single chip, a modem III, a modem II, a high voltage isolator III, a high voltage isolator IV, an ABL (Atlas Basic Language) code amplifier, a full wave rectification detector, a singlechip decoder, a PID (Proportion Integration Differentiation) temperature controller, an actuator element and a temperature sensor. The invention not only realizes the remote temperature control but also saves the cost.

Description

technical field [0001] The invention relates to a remote temperature controller which uses a power line carrier to transmit computer temperature control information. Background technique [0002] At present, in places requiring temperature control, such as factory laboratories, hotel room air conditioners, and hospital wards, one machine, one control is generally used, and it must be managed in a decentralized manner. Manual adjustment and inspection are not only a waste of manpower, but also the control is not good. Convenient, while wiring is also very inconvenient. Contents of the invention [0003] The invention provides a remote temperature controller which transmits computer temperature control information by using a power line carrier wave, which not only can realize remote temperature control, but also saves costs. [0004] The present invention adopts the following technical solutions: a remote temperature controller that uses power line carrier to transmit compu...
