Extendable minimum connection wire scanning type interactive system for dehumidifier

Abstract

The invention relates to an interactive system of a dehumidifier, in particular to an extendable minimum connection wire scanning type interactive system for the dehumidifier. An I / O port is adopted by an existing dehumidifier system for directly controlling input and output, and the requirement for a processor is high; a power panel, a control panel and a display panel are far away from one another, connection wiring harnesses are complex, the cost is high, and reliability is poor. The extendable minimum connection wire scanning type interactive system for the dehumidifier comprises a power panel, an operation panel and a display panel and is characterized in that the operation panel is provided with buttons and parallel-in serial-out chips, the display panel is provided with a display screen and serial-parallel conversion chips, the power panel is provided with a processor, a power supply and a motor, the buttons are connected with the processor through the parallel-in serial-out chips, the processor is connected with the display panel through the serial-parallel conversion chips, and the multiple serial-parallel conversion chips are provided and connected in a cascade mode. According to the technical scheme, a serial data connecting mode is adopted, the requirement for the number of processor ports is lowered, the number of connection wires are reduced greatly, the reliability of the system is improved, the system is extendable, and development and upgrading maintenance of subsequent products are facilitated.

Description

technical field [0001] The invention relates to an interactive system of a dehumidifier, in particular to an extensible minimum connection scanning interactive system for the dehumidifier. Background technique [0002] The original dehumidifier system uses the I / O port to directly control the input and output, which has high requirements for the processor (MCU); and the distance between the power board, control board, and display board of this system is relatively long, and the wiring harness is complicated, resulting in high system cost. , poor reliability. Contents of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to perfect and improve the existing technical solutions, and to provide a multifunctional dehumidifier device with a new type of human-computer interaction equipment, so as to increase the reliability of the dehumidifier and reduce the cost the goal of. For this reason, the present invent...
