Abstract
The utility model discloses the signal transmission assemblies for scanner, it include the first bus interface module for being connect with scanner, processing module, trigger signal interface module, second bus interface module and network output module, first bus interface module, trigger signal interface module is connected with processing module respectively with the second bus interface module, the network output module and the connection of the second bus interface, the form driver sweep rifle that the signal transmission assembly processing module for scanner of the utility model issues scan command to scanner works, network transmission is carried out by network output module again after carrying out dissection process in data back to processing module after scanner scanning simultaneously.
Description
Technical field
The utility model is related to scanner fields, more particularly to are used for the signal transmission assembly of scanner.
Background technology
The high-tech product that scanner is combined closely as technologies such as optics, machinery, electronics, software applications is after keyboard
With the main computer input apparatus of the third generation after mouse, scanner needs purchase to open external sensor in normal use
The key of function could external sensor carry out driver sweep, and the information after scanning can only processing locality show, cannot pass through
Network goes out data transmission, therefore very inconvenient when in use.
Utility model content
The technical issues of the utility model solves, which is to provide a kind of convenience and carries out network transmission to the data after scanning, to be used for
The signal transmission assembly of scanner.
Technical solution adopted by the utility model to solve its technical problems is：For the signal transmission assembly of scanner,
Include the first bus interface module for being connect with scanner, processing module, trigger signal interface module, the second bus interface
Module and network output module, first bus interface module, trigger signal interface module and the second bus interface module point
It is not connected with processing module, the network output module and the connection of the second bus interface.
It is further：The network output module include sequentially connected network control chip, data pump chip group and
RJ45 interfaces, the network control chip and the connection of the second bus interface module.
It is further：The model RTL8139D of the network control chip.
It is further：The chip model of the processing module is STC89c52.
It is further：Optical coupling module, the triggering are provided between first bus interface module and processing module
Optical coupling module is provided between Signal interface module and processing module.
The utility model has the beneficial effects that：The signal transmission assembly processing module for scanner of the utility model to
The form driver sweep rifle of scanner publication scan command works, while the data back after scanner scanning is to handling mould
Network transmission is carried out by network output module again after carrying out dissection process in block.
Description of the drawings
Fig. 1 is the signal transmission assembly schematic diagram for scanner.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
Signal transmission assembly for scanner as shown in Figure 1 includes that the first bus for being connect with scanner connects
Mouth mold block, processing module, trigger signal interface module, the second bus interface module and network output module, first bus
Interface module, trigger signal interface module are connected with processing module respectively with the second bus interface module, and the network exports mould
The chip model of block and the connection of the second bus interface, the processing module is STC89c52, when in use, trigger signal interface mould
Block is connect with extraneous sensor, such as：Photoelectric sensor, pressure sensor etc., the trigger signal interface module connect for sensor
Mouthful, the first bus structures module is connect with extraneous scanner, the network output module and extraneous network connection, specific work
When making, trigger signal is reached processing module by extraneous sensor by trigger signal interface module, and processing module is by trigger signal
It is converted to command signal and reaches scanner control scanner and be scanned operation, scanner is by the information back after scanning to processing
In module, processing module is sent data by network output module after parsing data, and the utility model is used to sweep
The signal transmission assembly processing module for retouching rifle works to the form driver sweep rifle of scanner publication scan command, sweeps simultaneously
It retouches and network transmission is carried out by network output module again after carrying out dissection process in the data back to processing module after rifle scanning.
On the basis of the above, the network output module includes sequentially connected network control chip, data pump chip group
With RJ45 interfaces, the model RTL8139D of the network control chip, the RJ45 interfaces with external network for being connected
It connects, the network control chip and the connection of the second bus interface module, the data pump are also designated as network transformer or can claim
For network isolation transformer, when the varying level of the heterogeneous networks equipment room of isolation cable connection, to prevent different voltages logical
Cross network cable transmission damage equipment.In addition to this, data mercury can also play the role of equipment certain lightning protection.
On the basis of the above, optical coupling module is provided between first bus interface module and processing module, it is described to touch
Optical coupling module is provided between signalling interface module and processing module, the setting of the optical coupling module can be by input, outlet side
Circuit carries out effective isolation electrically；Signal can be transmitted in the form of light；There is preferable anti-jamming effectiveness；Export lateral circuit energy
It is avoided the introducing and impact of strong voltage to a certain extent.
Particular embodiments described above has carried out into one the purpose of this utility model, technical solution and advantageous effect
Step is described in detail, it should be understood that the foregoing is merely specific embodiment of the utility model, is not limited to this
Utility model, within the spirit and principle of the utility model, any modification, equivalent substitution, improvement and etc. done should all wrap
Containing being within the protection scope of the utility model.
