Fig. 2 is the annexation figure of the USB function driver module built-in function unit of drive unit of the present invention.
Embodiment
The present invention is described further below by specific embodiment and accompanying drawing.
As shown in Figure 1, a kind of drive unit of the M2M module with USB interface, comprise WinCE operating system already provided USB main control driver module and on the usb bus driver module and the MODEM driver module and on the dialing application module, USB function driver module between usb bus driver module and MODEM driver module, USB function driver module is used to connect usb bus driver module and MODEM driver module.
Described as shown in Figure 2 USB function driver module comprises initialization unit, storage unit, function interface unit, reads thread units and connection status unit, initialization unit is connected with the function interface unit with storage unit and is used for storage unit and function interface unit are carried out initialization operation, the function interface unit respectively with storage unit, read thread units and be connected with the connection status unit and finish calling and to reading the initialization operation of thread units and connection status unit, be connected with storage unit and finish calling respectively storage unit to storage unit to reading thread units; The function interface unit also is connected with the usb bus driver module with the MODEM driver module of outside respectively, be used to realize the MODEM driver module to the calling with USB function driver module by the function interface unit of function interface unit to the calling of usb bus driver module, to read thread units and connection status unit be connected with the usb bus driver module respectively be used to finish with USB function driver module by its calling to the usb bus driver module.
Can implement the present invention for the ease of those of ordinary skill in the art, now in conjunction with the accompanying drawings the specific implementation process of each unit in the USB function driver module be done detailed description.
Storage unit: the realization of storage unit has dual mode.
Mode one: preserve the data that read from the M2M module with static BUFFER (buffer zone).The size of this BUFFER is provided with according to concrete hardware environment, and this BUFFER is embodied as a quiet cycle formation.Concrete mode is: two variablees of initialization, represent head of the queue respectively and to tail, when when the M2M module is read data, the number that the increase of tail of the queue variable is read, when data are sent to the MODEM driver module, the head of the queue variable increases the number that transmits, and will note judging the situation of queue empty and queue full here.
Mode two: preserve the data that read from the M2M module with dynamic BUFFER.Creating one has only reading of each initiation to ask the so big static BUFFER of number, with the temporary transient data that read from the M2M module of preserving of this static state BUFFER, data are read behind this static state BUFFER again according to actual dynamic BUFFER of data number application that reads from the M2M module.In dynamic BUFFER, the form with chained list is together in series each so dynamic BUFFER at last the copying data among the static BUFFER.Here also to represent linked list head and chained list tail respectively, when slave unit reads data dynamic BUFFER be inserted in the chained list tail with two pointers, and mobile tail pointer.When the higher-layer programs request msg, return the data in the linked list head, and the slip-on head pointer, discharge this dynamic BUFFER then.
The selection of above storage unit implementation will be judged according to the hardware environment of reality, if bad judgement can all realize dual mode, and then come test performance.
Connection status unit: be used for the dialing application module when initiating dialing or disconnecting request, whether inquiry M2M module is current connects outside 3G network, if connection status changes, USB function driver module triggers the MODEM driver module that events corresponding is notified the upper strata, its specific implementation method is: send the self-defining M2M module queries connection status of ordering of M2M module manufacturer, create a thread in the dialing application module before the order of M2M module Sending dialled number, this thread regularly says the word to the M2M module and inquires the connection status of M2M module.
Initialization unit: can at first move initialization unit when USB function driver module loads, this unit carries out the initial work of current USB function driver module, and its specific implementation process has two steps:
1. at first, if the storage unit that employing mode one realizes when the operation initialization unit, create a static BUFFER, and two variablees of pointer is end to end represented in initialization.If the storage unit that the mode that adopts two realizes then needs the pointer end to end of initialization chained list.
2. then, initialization unit obtains the USB essential information of M2M module, comprises device descriptor, configuration descriptor, interface descriptor, endpoint descriptor and character string descriptor.Just can judge whether to support this equipment according to the information USB function driver module in these descriptors.Initialization unit can also send a command to configuration and the interface that the M2M module is selected needs by the usb bus driver module according to actual conditions.
Function interface unit: the function interface that this unit provides it to need for upper strata MODEM driver module.Mainly comprise with lower interface:
1.OPEN interface mainly is engaged in following operation:
The USB endpoint descriptor of the M2M module that a. obtains with initialization unit in this interface is set up the communication pipe of main frame and M2M module.
B. create (initialization) and read thread units.
2.IOCTL interface: because current USB function driver module need show the MODEM driver module to the upper strata with the form of serial port drive, so the control command in this interface need be embodied as the control command of serial port drive, the control command relevant with serial ports hardware need not realize, directly returns success.It is that this driving must realize that but the several Control order is arranged:
＜1〉GET_WAIT_MASK: the incident mask value of current preservation is returned to the MODEM driver module.
＜2〉SET_WAIT_MASK: current incident mask value is arranged to the value that the MODEM driver module passes over.
＜3〉WAIT_ON_MASK: detect whether to have in the incident of incident mask setting and be triggered, the words that have are then returned the event flag of triggering at once and are given the MODEM driver module, otherwise wait for always, just return after the incident that is provided with in the incident mask is triggered.
＜4〉GET_COMMSTATUS: the data number that returns among the current BUFFER is given the MODEM driver module.
＜5〉GET_MODEMSTATUS: the state that returns current MODEM is given the MODEM driver module.
＜6〉SET_TIMEOUTS: the value of time-out time being arranged to the MODEM drive module setting.
＜7〉GET_TIMEOUTS: the time-out time value of preserving is returned to the MODEM driver module.
3.READ interface: the data among the storage BUFFER in the storage unit are returned to the MODEM driver module, then the slip-on head pointer.
4.WRITE interface: the MODEM driver module is passed the pipeline of writing that the data come have set up by initialization unit send to the M2M module.
Read thread units, this unit is created by the OPEN interface, regularly send read request with the pipeline of having set up of reading, read after the data according to concrete storage implementation and data are deposited in static state or dynamically among the BUFFER, and trigger events corresponding and give the MODEM driver module to the M2M module.
Those of ordinary skill in the art will appreciate that embodiment described here is in order to help reader understanding's principle of the present invention, should to be understood that protection scope of the present invention is not limited to such special statement and embodiment.Those of ordinary skill in the art can make various other various concrete distortion and combinations that do not break away from essence of the present invention according to these technology enlightenments disclosed by the invention, and these distortion and combination are still in protection scope of the present invention.
