Abstract

The utility model relates to a network drum washer which is formed by that a conventional drum washer and the technology of intelligent network are combined organically, and thus, the drum washer can mutually communicate with external network equipment; meanwhile, the information of the external network equipment can be obtained through the drum washer. The utility model has the advantages that the drum washer can be controlled remotely through the network; the control procedure of the drum washer can be updated in a manufacturer to upgrade the function of the drum washer; the operating state of the drum washer can be enquired at any time; the running fault state of the drum washer can be fed back to a maintenance department of the manufacturer to obtain accurate and timely maintenance.

Description

Network roll washing machine

The utility model relates to a kind of roller washing machine, a kind of roller washing machine with network function of more specifically saying so.

Quickening along with modern's rhythm of life, more and more higher to the demand on the household electrical appliance function, and existing roller washing machine still has following weak point: as being provided with of it must the scene directly with button operation, Long-distance Control can not be realized, maintenance department can not be fed back to immediately to safeguard targetedly the fault that occurs.Sometimes the consumer is away from home, and then can't understand the duty of washing machine.

At the problems referred to above, the purpose of this utility model provides a kind of network roll washing machine that can realize Long-distance Control and information transmission.

The technical solution of the utility model is with traditional roller washing machine and the organically combination of intelligent network technology, makes roller washing machine and outside network device can carry out two-way communication function, and can be in the information of obtaining on the roller washing machine on the outside network device.

The utility model has the advantages that and to realize Long-distance Control by network to roller washing machine; Can upgrade the control program of roller washing machine from manufacturer, its function is upgraded; Can inquire about the duty of roller washing machine at any time; The operating malfunction of roller washing machine can be fed back to the maintenance department of manufacturer, make maintenance more accurate, timely.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment.

Fig. 1 is a theory diagram of the present utility model.

Fig. 2 is the circuit theory diagrams of the utility model communication and display part.

The utility model comprises an existing roller washing machine 5, it is characterized in that it also comprises central processing unit (CPU) 1 and is solidificated in wherein program, liquid crystal display 2, communication interface circuit 3 and power circuit 4.

Wherein, it is the chip of M38027E8SP that central processing unit (CPU) 1 adopts model, and all programmed instruction all are to be carried out by it, control external unit by it and carry out which kind of action.

Power circuit 4 can be the backlight power supply of circuit board and display.Among the figure, ACIN is for exchanging inlet wire, and the secondary voltage of transformer is 7V.Alternating voltage is the DC voltage of 7V * 0.9=6.3V after the RF rectification, this DC voltage send the input of three terminal regulator 7805 after C1, C2 filtering, and 7805 are output as stable+5V voltage, power to circuit board; In addition, the 6.3V DC voltage after the RF rectification also is used as the backlight power supply of display, and whether the connection of this power supply, by the control of the P1.5 mouth on the CPU, when P1.5 mouth output high level, relay R Y gets by program, with its closing of contact, make backlight luminous; When the P1.5 mouth is output as low level, relay R Y dead electricity, open its contact, and backlight is then not luminous; The use of backlight makes no matter network roll washing machine is by day, still at night, can both demonstrate literal and image clearly on the display.

Liquid crystal display 2 comprises LCD and LCD controller, adopts lattice lcd display on the network roll washing machine, and 1 pin FG of its controller connects shell, must link to each other with the earth, to guarantee effective shielding, makes demonstration not be subjected to external interference; 2 pin VSS are the power supply common port; 3 pin VDD are+the 5V power end; 4 pin VEE are-the 10V power end; 5 pin WR link to each other with the 58 pin P3.6 mouths of CPU for writing control end; 6 pin RD link to each other with the 57 pin P3.7 mouths of CPU for reading control end, and WR, RD are subjected to the control of CPU respectively, finish the reading and writing operation to LCD jointly; 7, the CE of 8 pin, C/D are the sheet selected control system signal of LCD, link to each other with P1.1, the P1.2 mouth of CPU respectively; 9,20 pin are dead end, not line; 10 pin link to each other with the 45 pin P1.3 mouths of CPU for reset signal RESET end; 11～18 pin of LCD are respectively its data/address bus D0～D7, are connected with P0.0～P0.7 mouth of CPU respectively, and the data of finishing displaying contents on the display transmit; ES is connected with the power supply common port of whole system, finishes the demonstration control to the network roll washing machine human-computer interaction interface thus.

In order to make roller washing machine realize network function, between roller washing machine electric-control system and external web environment, increase communication interface circuit 3, and link to each other with central processing unit 1 with RXD by serial ports control end TXD.Wherein, TXD is a signal receiving end, and RXD is a signal sending end; In order to guarantee the safety of network roll washing machine circuit, in communication interface circuit 3, also be provided with two-way optically-coupled buffer circuit IS01, IS02, like this electric-control system of network roll washing machine just and the electric system of external network keep apart, the transmission of signal is only arranged between two electric systems, do not have public circuit to connect firmly, thereby effectively prevent of the breaking-up of extraneous high voltage roller washing machine internal core circuit; Serial communication chip 6 (model is MAX232) is finished the function of level conversion, the Transistor-Transistor Logic level in the single-chip microcomputer is converted to the RS-232 communication level of standard; Satisfactory communication signal is drawn from 7,8 pin of serial communication chip 6, be connected to external communication interface PIN3, thereby realized the network control function of network roll washing machine.
