Multi-split air conditioner remote monitoring system

Abstract

The invention discloses a multi-split air conditioner remote monitoring system. The multi-split air conditioner remote monitoring system comprises an upper controller, wherein an output end of the upper controller is connected with a switch, an output end of the switch is connected with a plurality of wireless transmission modules for signal transmission, and an output end of each wireless transmission module is connected with a plurality of air conditioning area subsystems; each air conditioning area subsystem comprises an execution module; each execution module is used for receiving and identifying signals transmitted by the upper controller, converting the identified transmitted signals into signal languages in the corresponding air conditioning area subsystem, and then sequentially transmitting the signals; and output ends of the execution modules are connected with an air-conditioning outdoor unit. According to the multi-split air conditioner remote monitoring system, an RF transceiver is additionally arranged into each wireless transmission module, so that the wireless communication function of information is realized, the function is easy to realize and expand, and differentsignal frequencies can be converted for different areas through the RF transceivers, so that the error reception of the signals is avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioner monitoring, in particular to a multi-line remote monitoring system. Background technique [0002] In related technologies, multi-connected devices generally need to be independently controlled by hand operators in their respective rooms. If the system is too large, it is impossible to monitor the status of each multi-connected indoor unit and outdoor unit in real time, which is inconvenient for centralized management and control, requires a lot of manpower for maintenance, greatly increases management costs, and seriously wastes system energy. [0003] After retrieval, Chinese Patent Grant No. CN207652463U discloses a centralized control system for equipment. Among them, the system includes: a host computer, a switch, and multiple subsystems; each subsystem includes: a controller, a gateway, a multi-line external machine, and multiple multi-line internal machines; the host computer is con...

Problems solved by technology

[0004] Although the solution disclosed above has solved the problem of flexible splicing and expansion, and realized the modularized multi-connection construction and centralized monitoring of the system, the signal transmission still uses cable transmission, so the installation of the monitoring system must be completed during the room decoration. However, installation in the later stage will consume a lot of manpower and material resources. Therefore, the stability of the signal transmission of the monitoring system and the simple installation can be realized, which is an urgent problem to be solved.
