In existing, if when peripheral serial equipment carries out serial communication by physical serial interface and opertaing device, all needing application developer is driving of this periphery serial equipment exploitation.Application developer need to relate to a lot of details when the driving of the peripheral serial equipment of exploitation, for example, how the how initialization of peripheral serial equipment receives and send data, how to resolve and encapsulated data packet, how to manage its power supply so that power saving etc.Therefore, for application developer, it needs to be grasped enough ins and outs, and needs the long construction cycle of cost can develop the driving that is suitable for some concrete peripheral serial communication equipment.
Just think, if the manufacturer of peripheral serial equipment or third party developer make a virtual serial port with driving corresponding to peripheral serial communication equipment and are loaded by the operating system of opertaing device, so, then shielded all ins and outs to this periphery serial equipment bottom operation, and its ins and outs are finished by the driving of virtual serial port.Like this, for application developer, its need then can be realized the control to this periphery serial equipment by the virtual serial port on the control opertaing device, and do not spend the bottom operation of being concerned about this periphery serial equipment.And all application developer all can be controlled peripheral serial equipment by the virtual serial port of controlling on this opertaing device.
According to above-mentioned design, as shown in Figure 1, be a kind of method of controlling peripheral serial equipment of the embodiment of the invention one, comprising:
S11, basis are preset the serial ports configuration information, the physical serial interface of peripheral serial equipment are converted to the virtual serial port of opertaing device;
Virtual serial port refers to opertaing device under the condition that does not increase any hardware, by certain operation, sets up VSP (the Virtual Serial Port: virtual serial port) of peripheral serial equipment in its operating system.So, application developer can use virtual serial port and peripheral serial equipment to carry out serial communication as the standard serial port that uses operating system.Virtual serial port is equivalent to set up the data link of an endless between opertaing device and peripheral serial equipment, application developer can think that peripheral serial equipment is directly connected on the opertaing device.
In this step, opertaing device can convert the physical serial interface of peripheral serial equipment to the virtual serial port of opertaing device according to default serial ports virtual information.So, application developer namely can be exchanged into the operation of the physical serial interface of externally enclosing serial equipment to the operation of this opertaing device virtual serial port.
Peripheral serial equipment can carry out the equipment of serial communication based on physical serial interface and opertaing device for all, such as bar code scan equipment etc.In existing, when opertaing device converted the physical serial interface of bar code scan equipment to virtual serial port on the opertaing device, application developer can realize the control to peripheral serial equipment by the virtual serial port on the control opertaing device.Wherein, opertaing device can be PDA etc.
S12, receive the control information that the virtual serial port to described opertaing device operates;
In this step, the operation that the control information that application developer is inputted at opertaing device is corresponding comprises the operations such as access to the virtual serial port of described opertaing device, reading and writing.
S13, the operation to described virtual serial port that described control information is corresponding convert the operation to the physical serial interface of described peripheral serial equipment to.
Among the step S13, opertaing device also sends this control information to described peripheral serial equipment by described virtual serial port after the control information that has received the application developer input.Peripheral serial equipment responds the operation to the virtual serial port of described opertaing device corresponding to described control information, and operating result is returned to opertaing device.So, namely can the operation to described the above virtual serial port of opertaing device that described control information is corresponding convert the operation to the physical serial interface of described peripheral serial equipment to.
In step S11-S13, convert the virtual serial port of opertaing device to by the physical serial interface with peripheral serial equipment, like this then so that application developer all can convert operation to peripheral serial equipment to the operation of the virtual serial port of opertaing device.Therefore, all application developer are by the described virtual serial port on the control opertaing device, can realize the control to peripheral serial equipment, such as access, the peripheral serial ports opertaing device of reading and writing etc., and the realization that does not spend the bottom operation of being concerned about this periphery serial equipment is (such as the how initialization of: peripheral serial equipment, how to receive and to send the realization of the bottom operations such as data), thereby reduced the development amount of application developer, and also so that this virtual serial port has certain versatility and ease for operation.
As shown in Figure 2, be a kind of method of controlling peripheral serial equipment of the embodiment of the invention two, comprising:
S21, the default serial ports configuration information of reception;
In the specific implementation, convert in the physical serial interface with peripheral serial equipment before the virtual serial port of opertaing device, also need to receive the default serial ports configuration information that the developer imports, described default serial ports configuration information specifically comprises: the physical serial interface of the configuration file of the log-on message of the described virtual serial port that the developer arranges, the described virtual serial port of configuration and default described peripheral serial equipment converts the driver of the virtual serial port of described opertaing device to.
Wherein, described opertaing device is built-in with operating system, and described basis is preset the serial ports configuration information, converts the physical serial interface of peripheral serial equipment the virtual serial port of opertaing device to, specifically comprises:
At first, the log-on message that the operating system basis receives, the title of the driving of the loading sequence of the virtual serial port that identification need to load, port numbers and correspondence.The driving name of the correspondence of the virtual serial port that for example, need to load is called: VirualCom.dll, port numbers is 9.
What need explanation a bit is, the operating system in the embodiment of the invention can be existing all operations system, Windows series operating system for example, the operating system of Vista series etc.
Need explanation on the other hand, the developer is when arranging the log-on message of described virtual serial port, and employed development language does not have clear and definite restriction, for example can be C language, C Plus Plus, assembly language etc.In embodiments of the present invention, described developer all refers to manufacturer or the third party developer of peripheral serial equipment, is not application developer.
Secondly, described operating system is according to the configuration file of developer's configuration, for example, bib configuration file according to this virtual serial port of developer configuration, the physical serial interface that loads described peripheral serial equipment converts the driver of the virtual serial port of described opertaing device to, in order to when operating system generates, guarantee to comprise in this operating system this driver.What need explanation a bit is, the developer is when the configuration file of this virtual serial port of configuration, and employed development language does not have clear and definite restriction, for example can be C language, C Plus Plus, assembly language etc.
At last, the physical serial interface of the described peripheral serial equipment of described operating system converts the driver of the virtual serial port of described opertaing device to, finishes the physical serial interface of described peripheral serial equipment to the conversion of the virtual serial port of opertaing device.
Need to prove that when the developer converted the driver of virtual serial port of opertaing device in the physical serial interface of default peripheral serial equipment, employed development language did not have clear and definite restriction, can be C language, C Plus Plus, assembly language etc.
For example, when the physical serial interface of presetting peripheral serial equipment with C Plus Plus converts the driver of virtual serial port of opertaing device to, developer (manufacturer or the third party developer that comprise peripheral serial equipment, be different from application developer) can finish with the COM_Init function initialization of peripheral serial equipment, open the physical serial interface of peripheral serial equipment with the COM_Open function, and pass through the control information of to the periphery serial equipment transmission of this physical serial interface application developer input.For example, also control the closing of physical serial interface of peripheral serial equipment with the COM_Close function; Finish communication baud rate to physical serial interface with the COM_IOControl function, parity bit, the setting of data bit, hardware flow and device power supply (DPS) management can be encapsulated in this function some control functions of peripheral serial equipment certainly.Unload peripheral serial equipment with the COM_Deinit function, come the encapsulation of paired data bag and given peripheral serial equipment Packet Generation with COM_Write.Come reading and resolving of paired data bag with the COM_Read function, and transferred data to opertaing device.
S22, basis are preset the serial ports configuration information, the physical serial interface of peripheral serial equipment are converted to the virtual serial port of opertaing device;
S23, receive the control information that the virtual serial port to described opertaing device operates;
S24, the operation to described virtual serial port that described control information is corresponding convert the operation to the physical serial interface of described peripheral serial equipment to.
Wherein, the operation of step S22-S24 is identical with the operation of embodiment one step S11-S13, be not repeated in this description at this.
In embodiment one and this enforcement, peripheral serial equipment can carry out the equipment of serial communication based on physical serial interface and opertaing device for all, such as bar code scan equipment etc.When the developer converted the physical serial interface of bar code scan equipment to virtual serial port on the opertaing device, application developer can realize the control to bar code scan equipment by the described virtual serial port on the control opertaing device.So, all application developer do not spend the realization of the bottom operation of being concerned about this virtual serial port when exploitation is changed the application of bar code scan equipment, thereby have reduced the workload of application developer yet.
In the prior art, for the peripheral serial equipment that carries out serial communication by virtual serial port (such as bluetooth equipment etc.), it is that the virtual serial port of 1-9 carries out serial communication with third-party control devices (as the bluetooth equipment of WINCE system, the bluetooth equipment of Windows mobile system are housed) upper end slogan normally.Opertaing device (such as PC etc.) is by RDP(Remote Desktop Protocol: RDP) connect with third-party control devices, be the virtual serial port of 1-9 by control third-party control devices upper end slogan, and then control peripheral serial equipment.Yet, for port numbers third-party control devices very in short supply (as the bluetooth equipment of WINCE system, the bluetooth equipment of Windows mobile system etc. are housed), the port numbers that itself and peripheral serial equipment carry out the virtual serial port of communication may not be the interior arbitrary port numbers of 1-9, but port numbers is greater than 9 port numbers.At this moment, when PC connects when the bluetooth equipment of WINCE is housed by the RDP agreement, because its bluetooth equipment upper end slogan that can only find to be equipped with WINCE system, Windows mobile system is the arbitrary serial ports between the 1-9, so this moment, PC can not connect with peripheral serial equipment, controlled peripheral serial equipment.Thus, the present invention also provides a kind of method of controlling peripheral serial equipment, as shown in Figure 3, is a kind of method of controlling peripheral serial equipment of the embodiment of the invention three, comprising:
S31, according to default serial ports configuration information, convert third-party control devices middle-end slogan to arbitrary virtual serial port that third-party control devices middle-end slogan is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding; Described third-party control devices and peripheral serial equipment carry out serial communication by described port numbers greater than arbitrary virtual serial port of thresholding; Control connects with arbitrary virtual serial port that described third-party control devices middle-end slogan is less than or equal to thresholding;
Virtual serial port described in this step, the virtual serial port described in is identical with implementing, and no longer is repeated in this description at this.Thresholding described in this step, when the arbitrary virtual serial port that refers to opertaing device and third-party control devices connects, the maximum port numbers that this arbitrary virtual serial port is corresponding.
In the specific implementation, peripheral serial equipment can carry out the equipment of serial communication, for example bluetooth equipment A based on virtual serial port and third-party control devices for all.Third-party control devices is the equipment that is built-in with operating system, as the bluetooth equipment B of Wince system or windows mobile system is housed.If two bluetooth equipments connect by the serial port protocol of bluetooth, suppose that bluetooth equipment B use side slogan is that 12 bluetooth serial ports and bluetooth equipment A carry out serial communication.And opertaing device can be PC, and it connects by RDP and bluetooth equipment B.Owing to can only find the arbitrary serial ports of bluetooth equipment B middle-end slogan between 0 to 9 at the PC end.That is to say that 9 are connect with the opertaing device maximum port numbers corresponding to virtual port of time use of third-party control devices, namely 9 is thresholding.Because can't find port numbers on the PC and be 12 bluetooth serial ports, so just have no idea to access bluetooth equipment B.If PC is wanted to visit the bluetooth equipment A that connects with bluetooth equipment B by RDP, then need by in port numbers of bluetooth equipment B interpolation being the arbitrary virtual serial port between 0 to 9.Specific practice is exactly to be bluetooth equipment B upper end slogan that 12 bluetooth serial ports converts the arbitrary virtual serial port of bluetooth equipment B upper end slogan between 0 to 9 to, suppose with regard to virtual for virtual serial port 9, all be that the operation of 9 virtual serial port all can all transform bluetooth equipment upper end slogan to bluetooth equipment B upper end slogan are the operation of 12 bluetooth serial ports so, and PC just can be that 9 virtual serial port is controlled bluetooth equipment A by the port numbers of controlling bluetooth equipment B like this.
The control information that arbitrary virtual serial port that S32, receiving control apparatus transmit, that described third-party control devices middle-end slogan is less than or equal to thresholding operates;
In this step, application developer is input control information on opertaing device, and it is transferred to third-party control devices.Wherein, the operation corresponding to control information of application developer input comprises the operations such as reading and writing, control.
S33, the operation that described third-party control devices middle-end slogan is less than or equal to arbitrary virtual serial port of thresholding that described control information is corresponding convert to the operation of described third-party control devices middle-end slogan greater than arbitrary virtual serial port of thresholding, control described peripheral serial equipment.
Among the step S33, application developer is input control information on opertaing device, and it is transferred to third-party control devices.Such as, third-party control devices received described port numbers is the control information of 1 to 9 arbitrary virtual serial port after, be that arbitrary virtual serial port, the port numbers of 1-9 sends peripheral serial equipment to greater than arbitrary virtual serial port of 9 by port numbers successively with this control information.Peripheral serial equipment respond described control information corresponding be the operation of arbitrary virtual serial port of 1-9 to described third-party control devices middle-end slogan, and operating result is returned to third-party control devices.Third-party control devices also sends it to opertaing device after receiving described operating result.
In step S31-S33, convert third-party control devices middle-end slogan to arbitrary virtual serial port that third-party control devices middle-end slogan is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding, so that the operation that third-party control devices upper end slogan be less than or equal to the arbitrary virtual serial port of thresholding on of application developer by opertaing device input all can convert to the operation of third-party control devices upper end slogan greater than arbitrary virtual serial port of thresholding, and then be converted to operation to the virtual serial port of peripheral serial equipment.So, so that opertaing device can be realized the control to peripheral serial equipment by the arbitrary virtual serial port on the third-party control devices.
As shown in Figure 4, be a kind of method of controlling peripheral serial equipment of the embodiment of the invention four, comprising:
S41, the default serial ports configuration information of reception;
In the specific implementation, opertaing device middle-end slogan is converted to before arbitrary virtual serial port that opertaing device middle-end slogan is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding, also comprise receiving default serial ports configuration information, described default serial ports configuration information specifically comprises:
Log-on message, configuration described that the third-party control devices upper end slogan that the developer arranges is less than or equal to arbitrary virtual serial port of thresholding is less than or equal to the configuration file of arbitrary virtual serial port of thresholding and default described port numbers and converts the driver that described port numbers is less than or equal to arbitrary virtual serial port of thresholding to greater than arbitrary virtual serial port of thresholding.
Wherein, described third-party control devices is built-in with operating system, such as the WINC system, or the Windows system, convert opertaing device middle-end slogan to arbitrary virtual serial port that opertaing device middle-end slogan is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding, be specially:
At first, the log-on message that the operating system basis receives, the title of the driving of the loading sequence of the virtual serial port that identification need to load, port numbers and correspondence.The driving name of the correspondence of the virtual serial port that for example, need to load is called: VirualCom.dll, port numbers is 9.When this was in the port numbers that virtual serial port is set, it was the arbitrary virtual serial port that is less than or equal to thresholding that port numbers can only be set, and was arbitrary virtual serial port between the 1-9 such as port numbers.
What need explanation a bit is, the developer is when arranging the log-on message of the described arbitrary virtual serial port that is less than or equal to thresholding, and employed development language does not have clear and definite restriction, for example can be C language, C Plus Plus, assembly language etc.In embodiments of the present invention, described developer all refers to manufacturer or the third party developer of peripheral serial equipment, is not application developer.
Secondly, operating system is according to described configuration file, loads described port numbers and converts the driver that described port numbers is less than or equal to arbitrary virtual serial port of thresholding to greater than arbitrary virtual serial port of thresholding.For example, operating system is the bib configuration file (wherein 9 are thresholding) of 9 virtual serial port according to the port numbers of developer configuration, the loading end slogan is the driver that 12 virtual serial port converts 9 virtual serial ports to, in order to when operating system generates, guarantee to comprise in this operating system this driver.What need explanation a bit is, when the developer was less than or equal to the configuration file of arbitrary virtual serial port of thresholding in configuration, employed development language did not have clear and definite restriction, for example can be C language, C Plus Plus, assembly language etc.
At last, the described port numbers that the described developer of described operating system presets converts the driver that described port numbers is less than or equal to arbitrary virtual serial port of thresholding to greater than arbitrary virtual serial port of thresholding, finishes described port numbers and converts the conversion that described port numbers is less than or equal to arbitrary virtual serial port of thresholding to greater than arbitrary virtual serial port of thresholding.
Wherein, when the developer converted described port numbers to and is less than or equal to the driver of arbitrary virtual serial port of thresholding greater than arbitrary virtual serial port of thresholding in default described port numbers, employed development language did not have clear and definite restriction, for example can be the C language, C Plus Plus, assembly language etc.
For example, when presetting the arbitrary virtual serial port of described port numbers greater than thresholding with C Plus Plus and convert described port numbers to and be less than or equal to the driver of arbitrary virtual serial port of thresholding, developer (manufacturer or the third party developer that comprise peripheral serial equipment, be different from application developer) can finish with the COM_Init function initialization of peripheral serial equipment, open virtual serial port corresponding to peripheral serial equipment with the COM_Open function, and pass through the control information of to the periphery serial equipment transmission of this virtual serial port application developer input.For example, also control the closing of virtual serial port of peripheral serial equipment with the COM_Close function; Finish communication baud rate to virtual serial port with the COM_IOControl function, parity bit, the setting of data bit, hardware flow and device power supply (DPS) management can be encapsulated in this function some control functions of peripheral serial equipment certainly.Unload peripheral serial equipment with the COM_Deinit function, come the encapsulation of paired data bag and given peripheral serial equipment Packet Generation with COM_Write.Come reading and resolving of paired data bag with the COM_Read function, and transferred data to opertaing device.
S42, according to default serial ports configuration information, convert third-party control devices middle-end slogan to arbitrary virtual serial port that third-party control devices middle-end slogan is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding; Described third-party control devices and peripheral serial equipment carry out serial communication by described port numbers greater than arbitrary virtual serial port of thresholding; Arbitrary virtual serial port that opertaing device and described third-party control devices middle-end slogan are less than or equal to thresholding connects;
The control information that arbitrary virtual serial port that S43, receiving control apparatus transmit, that described third-party control devices middle-end slogan is less than or equal to thresholding operates;
S44, the operation that described third-party control devices middle-end slogan is less than or equal to arbitrary virtual serial port of thresholding that described control information is corresponding convert to the operation of described third-party control devices middle-end slogan greater than arbitrary virtual serial port of thresholding, control described peripheral serial equipment.
Wherein, the operation of step S42-S44 is identical with the operation of embodiment three step S31-S33, be not repeated in this description at this.
In the present embodiment, third-party control devices is according to the default serial ports configuration information that receives, convert its upper end slogan to arbitrary virtual serial port that port numbers is less than or equal to thresholding greater than arbitrary virtual serial port of thresholding, so that the operation that third-party control devices upper end slogan be less than or equal to the arbitrary virtual serial port of thresholding on of application developer by opertaing device input all can convert to the operation of third-party control devices upper end slogan greater than arbitrary virtual serial port of thresholding, and then be converted to operation to the virtual serial port of peripheral serial equipment.So, so that opertaing device can be realized the control to peripheral serial equipment by the arbitrary virtual serial port on the third-party control devices, such as access, the peripheral serial ports opertaing device of read-write etc.
Correspondingly, as shown in Figure 5, the embodiment of the invention five also discloses a kind of opertaing device, comprising:
Wherein, described receiver module 51 also is used for receiving default serial ports configuration information, and described default serial ports configuration information specifically comprises for the developer presets:
The log-on message of described virtual serial port;
The configuration file of described virtual serial port;
