Problems solved by technology

The common feature of the above-mentioned prior art is that a remote control detector controls an air conditioner, which has the following disadvantages: it cannot meet the high reliability requirements for constant temperature in laboratories and other places, and once the air conditioner breaks down, The consequence of shutting down for maintenance is serious and inconvenient for maintenance; one air conditioner works alone, and its service life will naturally decrease; one air conditioner works alone, with a certain power to meet the changing cooling and heating needs, often large horses and small carts or small horses In the case of large vehicles, it is not economical and wastes energy
In the case of an existing air conditioner, if the power or other performance cannot meet the current requirements, replacement will cause waste

Embodiment Construction

[0010] Fig. 1 is specific embodiment 1 of the present invention. This is a dual-machine switcher that centrally controls the air conditioner. It consists of printed circuit boards and electronic circuits. The electronic circuit is composed of a dial switch connected with the I / O terminal of the single-chip computer of the remote control detector and two control circuits of machine A and machine B. The control circuit consists of a triode amplifier, an air conditioner connecting socket, a comparator and another triode amplifier. The comparator is composed of LM358 operational amplifier, the electronic filter is composed of 103N integrated circuit, and the single-chip computer is composed of TMP87PH46N integrated circuit. It can meet the high reliability requirements of laboratories and other occasions, and is easy to maintain. long lasting. Moreover, different air conditioners can be automatically allocated and used according to power requirements, which is economical and r...

Abstract

A dual-unit switching device for the commonly controlled air conditioners in order to choose one from two air conditioner for proper power is composed of PCB and electronic circuit consisting of coding switch connected to I / O pin of single-chip computer in remote-controlled detector and two controllers for both air conditioner. Said controller comprises amplifier, comparator, electronic filter and single-chip computer.

Description

technical field [0001] The invention relates to a monitoring device of an air conditioner, more specifically, a double-device switcher for centralized control of air conditioners capable of switching on and off switching and controlling two air conditioners at the same time. Background technique [0002] The existing centralized control air-conditioning system can receive the centralized control signal from the centralized control device by the microcomputer of the outdoor unit controller, control the outdoor unit according to the received centralized control signal, and further send the above-mentioned microcomputer to the indoor unit. The centralized control signal controls the indoor unit. Japanese Patent Application No. 59-210249 discloses such a technology. There is also a remote monitoring air-conditioning system, which controls the centralized controller through the computer through the modem, then controls the remote control detector by the centr...
