Abstract
The invention discloses a wireless sensor network-based printer interface device, which comprises two wireless transmission functional modules, wherein one wireless transmission module connected with a printer interface is named a printing node; each wireless transmission module connected with a computer is named a host node; and the printing node and the host node are connected with each other in a wireless mode to form a wireless sensor network. By the device, a wireless printing function is realized without cables, and a plurality of computers can share one computer; simultaneously, the wireless sensor network has the characteristics of electricity saving, short time delay, high confidentiality and the like and is reliable and safe; and the wireless sensor network is a wireless sensor network designed on the basis of an IEEE (Institute of Electrical and Electronic Engineers) 802.15.4 technical standard and a ZigBee network protocol.
Description
Technical field:
Patent of the present invention relates to a kind of printer interface device based on wireless sensor network, belongs to the wireless communications application technical field.
Background technology:
At present, printer is a kind of equipment commonly used in family and the office, and the connection of printer all links to each other with main frame by cable on the market.Too much line, printer cannot be careless on the desktop moves etc. and to have brought inconvenience all for vast user.The radio sensing network technology is applied on the printer, realize that printer wireless is printed and printer is shared.
Summary of the invention
Goal of the invention:
The purpose of patent of the present invention is the defective at the above-mentioned background technology, and a kind of printer interface device based on radio sensing network is provided, to realize the networking of computing machine and printer wireless.
Technical scheme:
Patent of the present invention adopts following technical scheme for realizing above-mentioned feature:
A kind of printer interface device based on radio sensing network, comprise two kinds of wireless transmission function modules, a wireless transport module that links to each other with printer interface in it is called print node, each wireless transport module that links to each other with computing machine is called host node, and print node and host node form a wireless sensor network by wireless connections.
Wherein, described wireless transport module is the wireless senser that adopts the Zigbee protocol stack.
Wherein, described printer interface is the LPT interface, and what described printer adopted is to be applicable to that the universal printer with Centronics parallel interface is the LPT printer.
Beneficial effect:
The present invention is in the function that does not have to have realized under the situation of cable wireless printing, and many computing machines can be shared a computing machine.Simultaneously, wireless sensor network has characteristics such as power saving, reliable, time delay weak point, safety, high security.This radio sensing network is based on IEEE 802.15.4 technical standard and ZigBee procotol and the wireless data sensor network that designs.
Description of drawings:
Fig. 1 is the overall construction drawing of radio sensing network printer interface device.
Fig. 2 is wireless transport module and printer interface connecting circuit figure.
Fig. 3 is wireless transport module and computing machine connecting circuit figure.
Specific embodiments:
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
As shown in Figure 1, radio sensing network printer interface device of the present invention comprises that two kinds of employing Zigbee protocol stack chip CC2430 are the wireless transmission function module of core.Wherein print node links to each other with printer interface, and host node links to each other with computing machine.As shown in Figure 3, computing machine is given host node data transmission by the RS232 interface, and the RS232 mouth adopts 8 bit data positions, 1 stop bit, and no parity, the serial port module baud rate is 115200, so CC2430 need be to the serial line interface setting of programming.Therefore host node is communicated by letter with print node by wireless sensor network, needs and its protocol stack is carried out initialization, makes up wireless sensor network, and transmits data.Print node by printer side receives order and the data that host node is sent, and the LPT interface output of control printer.
Printer interface of the present invention is the LPT interface, and it is connected with the parallel interface printer.As shown in Figure 2, the P0 mouth of data reception module processor CC2430 links to each other with 2～9 pins of printer interface and is used for the transmission of data, and P1.5 connects the BUSY port of printer interface, and P1.6 connects the gating end (STB) of printer interface.When wireless wireless transport module receives the data that PC sends, can be earlier with the BUSY end relatively, if BUSY busy (BUSY=1) just wait for, if the BUSY spare time (BUSY=0) P1.6 is realized by high level to low transition, thereby the printing of realization data.
Process of the invention process: the print node of printer side is provided with the preparation of carrying out slave unit after the initial parameter, waits for receiving data frames.And when the host node of host side is not busy, be in dormant state, when computing machine had the print data of transmission, host node entered duty, by interrupt handling routine accept data and will packing data handle after send.After print node receives print command and data by wireless sensor network, the control printer interface, thus realize the printer wireless printing.
The above only is an an example of the present invention, not in order to restriction the present invention, all in invention spirit and principle within done any modification, be equal to and replace and improvement etc., all should be included within protection scope of the present invention.
