Description
Technical field
The present invention relates to a kind of external device management system, especially a kind of self-service machine external device management system.
Background technique
Today's society, the substantially all too busy to get away various self-service devices of the clothing, food, lodging and transportion -- basic necessities of life of people, such as hospital
Registration machine, the automatic teller machine of bank, the ticket machine of subway etc..Many kinds of, feature-rich, the peripheral hardware needed of self-service machine
It also is varied naturally.And for a self-service machine system, it is to support a lot of peripheral hardwares.At present many times, when
It when replacing the external equipment of different model, generally requires to modify a large amount of code from top to bottom, that is because different is outer
Interface provided by portion's equipment is different.So self-service machine system just needs an outstanding system to remove management external equipment,
The cost in exploitation can be reduced as far as possible.
It is big that existing external device management system requires top-down modification when external equipment changes
The code of amount, because interface form provided by the external equipment of replacement is generally different.
Summary of the invention
In view of the above-mentioned defects in the prior art, the present invention provides the peripheral equipment management system and its use of a kind of self-service machine system
Method, the code for the modification system which enables self-service machine system as few as possible when replacing external equipment, accomplishes
It only needs to add device drives according to the template defined, modifies configuration file, that is, can provide connecing as same type equipment
Mouthful give operation layer use, thus efficiently, flexibly manage self-service machine system under diversified external equipment.

And operation layer.
Further, the hardware layer is peripheral hardware hardware required for various self-service machines, including USB interface device and serial ports
Interface equipment etc..
Further, the device drive layer: each peripheral hardware requires the exploitation that application layer driving is done according to business demand,
The corresponding dynamic library file of one equipment.These dynamic library files directly to hardware interaction, are sent downwards to relevant device
Specific instruction, while receiving response and message from equipment.Registration equipment upwards, and relevant software interface is provided,
So as to top level control equipment, the message from equipment is received.
Further, the equipment management layer dynamically manages the equipment for being connected to system, adds automatically in equipment insertion system
The driving for carrying equipment, when equipment removes system, the driving of automatic unloading equipment；By reading configuration file, peripheral hardware is driven
Be tied on the communication dynamics library of corresponding types in communication layers, set up communication layers to device drive layer bridge.
Further, the equipment communication layers can safeguard different type dynamic base according to different device types, logical downwards
The device drives that the binding of equipment management layer belongs to the type are crossed, communication bridge is established.DBUS is used up to build with protocol conversion layer
Vertical interprocess communication, exchanges data.
Further, the instruction parsing, the conversion that issue of the protocol conversion layer to operation layer, then be issued to by DBUS
In the process of the specified type of equipment communication layers.To data parsing, conversion that equipment communication layers upload, then pass through Websocket
Upload to operation layer.
Further, the operation layer defines relevant business according to the function of self-service machine, passes through with protocol conversion layer
Websocket communication.
The application method of the system is as follows:
The driving of step 1. modularized equipment, the device drives of self-service machine packaging bottom layer according to demand, this system require modularization to set
Standby driving, i.e. each peripheral hardware driving will write according to the template defined.Need to define module initialization interface, a mould
The anti-initialization interface of block, module input and output control interface and signal and slot interface, as follows:
static int module_init(void * args);

And use extern_module_declare (_ object_type, _ module_init, _ module_uninit,
...) register this module.
Step 2. is classified according to the device type of self-service machine；For example it is divided into camera class, printer class, card reader class
Etc., then safeguard the dynamic base of respective type.Such as Type_Camera.so, Type_Print.so, Type_
Reader.so.And it needs to register this module.
Step 3. configuration manager scans current chartered device drives and various types of dynamic bases, generates
One allocation list is selected to be used under current device type to be which kind of equipment, such as printer class, currently be needed to be used
It is the MS-NP80A of U.S. loose printer；Camera class, currently to be used is the XS-500E of first stone.According to selected collocation,
Generate a configuration file.
Step 4. equipment management service (DeviceManager) can use dlopen dynamic according to the content of configuration file
The specified device drives of load, and be tied to corresponding type dynamic base up.
Step 5. if being that operation layer is instructed to equipment transmission at this time, can then be given to instruction by websocket
Protocol conversion layer, business conversion layer can be parsed and be converted to instruction, then specified type dynamic base is given to by DBUS, by
Bind type dynamic base and device drives in preceding 4 step, so instruction can reach external set by device drive layer
It is standby, achieve the purpose that operation layer controls external equipment.If being external equipment active feedback information at this time to operation layer, outside that
The information of equipment feedback can be sent to protocol conversion layer by DBUS, agreement turns by device drive layer type dynamic base on earth
It changes layer and parsing conversion is carried out to information, then operation layer is sent to by websocket, reached operation layer and obtained external device status
Purpose.
The invention also includes the self-service machine for having above-mentioned self-service machine external management system, the self-service machine can be hospital
Registration machine, the automatic teller machine of bank, ticket machine of subway etc..
The present invention has the advantages that allowing equipment management layer dynamically to load and unload device driver module
Device drives, and upper layer application does not need interested devices and drives specific interface form, it is only necessary under send instructions and synchronous phase
The data structure answered can call the interface of device drives.Carry out the dynamic of bound device driving and respective type using configuration file
State library.This is done so that when needing replacing or adding specific external equipment, it is only necessary to which new device drives are registered to
In system, configuration file is reconfigured, new device drives can establish connection with upper layer application.Without each
The code of equipment management layer will be modified when more exchange device.Current unwanted equipment can also be dynamically uninstalled to drive
It is dynamic, it improves efficiency.
