In this embodiment, the location serial port drive is NMEA drive, and the location data is NMEA data. The positioning system driver is connected with the positioning serial port driver and the positioning device, acquires positioning data from the positioning device, and sends the positioning data to the positioning serial port driver. The positioning device is a general communication module with positioning and positioning information collecting functions, and the positioning device usually does not have a display interface. The positioning data is NMEA data, the reading request is a request signal for acquiring the NMEA data, and the positioning equipment processes the collected positioning information when acquiring the reading request, so that the positioning data is conveniently sent to the host computer side in the follow-up process.
Specifically, the positioning serial port driver and the positioning system driver are both program software drivers, so that the positioning serial port driver and the positioning system driver are in communication connection. After the positioning serial port driver and the positioning system driver are in communication connection, the positioning system driver sends a reading request to the positioning device to request to read the positioning data of the positioning device. Where the read request is typically sent in the form of an AT command or instruction.
In step S204, the positioning system driver receives the positioning data sent by the positioning device in response to the reading request.
When receiving the reading request, the positioning device will respond to the reading request and send the self-collected positioning data to the positioning system driver based on the reading request. The positioning equipment acquires the positioning data of the equipment through the baseband chip, and the principle of the positioning equipment is similar to that of a GPS, a GIS and the like. When the host computer recognizes the positioning device, the positioning system driver can realize communication between the host computer and the positioning device through a data interface mode.

Wherein the positioning application, i.e. the upper positioning application, is capable of presenting data to a user or host computer. After the positioning serial port driver receives the positioning data, the positioning data is directly sent to the positioning application program in a serial port mode, and therefore the positioning application program can obtain the positioning data.
In the positioning data transmission method based on Windows10, a positioning serial port driver is additionally arranged in a Windows10 operating system, positioning data of positioning equipment is acquired through the positioning system driver, the positioning system driver sends the data to the positioning serial port driver, and the positioning serial port driver uploads the positioning data to an upper positioning application program. The positioning data can be directly sent to the upper positioning application program in a serial port mode by additionally arranging the serial port driver in the Windows10 operating system, and the upper positioning application program does not need to be greatly changed, so that the upper positioning application program is adaptive to the current positioning system driver, and the positioning data is acquired in other data transmission modes except for function calling. According to the method and the device, the existing positioning application program does not need to be changed, and the positioning data can be acquired through other data transmission modes under the driving framework of the current positioning system.
In one embodiment, as shown in fig. 3, the positioning data transmission method based on Windows10 further includes a step of configuring to implement connection between the positioning serial driver and the positioning system driver, as shown in fig. 3, the step includes: the positioning serial port driver sends a request for opening a driving switch to the positioning system driver; the positioning system driver receives a request for opening a driving switch and opens a positioning serial port driver; and after the positioning serial port drive is opened, the positioning serial port drive is connected with the positioning system drive.
The request for opening the driving switch is an electric signal, is actively sent to the positioning system driver by the positioning serial port driver, and is used for opening the positioning serial port driver, so that the positioning serial port driver is connected with the positioning system driver, and can receive positioning data. After receiving a request for opening a drive switch of a positioning serial port drive, a positioning system drive executes the operation of opening the drive switch, and after the positioning serial port drive is opened, the positioning system drive sends a drive opening completion instruction to the positioning serial port drive, wherein the drive opening completion instruction is the inherent communication logic between the drives, namely after an A drive sends an X instruction to a B drive, the B drive must send a complete instruction to the A drive.
In the process of opening the positioning serial port driver, the host computer is required to call a subfunction ioctl _ gnss _ send _ drivercommand _ setmemalogging gnss _ nmeastrem _ start of the DeviceIOControl to generate a request for opening the driver switch.
In this embodiment, send to the positioning system drive through location serial ports drive and open the drive switch request, open the location serial ports drive by the positioning system drive again to location serial ports drive and positioning system drive establish the connection, make the location serial ports drive can receive the location data that the positioning system drive received.

3. the positioning equipment transmits positioning data to a positioning system driver;
4. the positioning system driver transmits the positioning data to a given bit interface driver;
5. and the positioning serial port driver sends the positioning data to the positioning application program.

Specifically, after the positioning system driver sends a reading request to the positioning device, the positioning serial port driver sends a data monitoring instruction to the positioning system driver. The positioning system driver can acquire the positioning information sent by the positioning equipment through the data listening instruction and the reading request. After the positioning system driver sends the reading request to the positioning device, the process of obtaining the positioning information is continuously carried out: the positioning serial port driver sends a data monitoring instruction to the positioning system driver, and the positioning system driver obtains positioning data (sent by the positioning device) according to the data monitoring instruction.
In the process of monitoring data by positioning the serial port driver, the host computer is required to call a sub-function ioctl _ gnss _ list _ nmea of the DeviceIOControl to generate a data monitoring instruction.
Generally, before the positioning system driver issues an AT command to the positioning device to read the positioning data, it is also necessary to: the positioning serial port driver sends a session opening instruction to the positioning system driver, a session can be understood as a communication protocol or a communication mechanism, and after the session is opened, the positioning system driver can normally realize communication interaction with the positioning system driver under the condition that the positioning system driver is opened. After the positioning system driver receives the session opening instruction, a session is established between the positioning system driver and the positioning serial port driver, and after the session is successfully established, the positioning system driver sends a session established instruction to the positioning serial port driver according to the inherent logic of drive communication, wherein the session established instruction is a complete instruction and indicates that the operation is completed.
In this embodiment, the data monitoring instruction is sent to the positioning system driver through the positioning serial port driver, so that the positioning system driver obtains the positioning data collected by the positioning device based on the data monitoring instruction and the reading request.
In one embodiment, before the positioning serial port driver directly sends the positioning data to the positioning application program, the method further includes:
the positioning serial port driver stores the positioning data received from the positioning system driver into a buffer area; and when the positioning serial port driver receives a data fetching request sent by the positioning application program, uploading the positioning data stored in the buffer area to the positioning application program.

Specifically, the positioning system driver immediately sends the positioning data to the positioning serial port driver every time the positioning data is obtained, and then the positioning serial port data stores the received positioning data in the buffer area. When the positioning application program needs to display the positioning data, the positioning serial port driver can actively send a data fetching request to the positioning serial port driver, and the positioning serial port driver can respond to the data fetching request and send the positioning data stored in the buffer area to the positioning application program.
In this embodiment, the buffer caches the positioning data obtained by the positioning serial driver, and when the positioning application program is needed, the positioning application program actively sends an access request to the positioning serial driver, and the positioning serial driver mutually responds to the access request and uploads the positioning data in the buffer to the positioning application program, so that the positioning application program obtains the positioning data.
As shown in fig. 3, the positioning data transmission method based on Windows10 includes a step of terminating listening in an end operation phase, and specifically includes:
1. the positioning serial port driver sends a monitoring termination instruction to the positioning system driver;
2. and the positioning system driver sends a reading termination instruction to the positioning equipment, so that the positioning equipment does not send positioning data to the positioning system driver any more.
The function of the termination monitoring instruction is to terminate monitoring and sense positioning data. And the positioning serial port driver sends the instruction to the positioning system driver, the positioning system driver immediately sends a reading termination instruction to the positioning equipment after obtaining the monitoring termination instruction, and the reading termination request is also sent in the form of an AT command or instruction. After receiving the reading termination request, the positioning device stops sending positioning data to the positioning system driver. And then, the positioning system driver sends a monitoring termination completion instruction to the positioning serial port driver.
In the process of terminating the snooping, the host computer is required to call the subfunction ioctl _ gnss _ stop _ fixsession of the DeviceIOControl to generate a terminate snooping instruction.
In this embodiment, the termination monitoring instruction is obtained by the positioning system driver, and when the termination monitoring instruction is received, a termination reading request is sent to the positioning device, so that when the positioning serial port driver is not required to obtain positioning data, the positioning device stops sending positioning data to the positioning system driver.

2. the positioning system driver receives a request for closing the driving switch and closes the positioning serial port driver; and after the positioning serial port drive is closed, the positioning serial port drive is disconnected with the positioning system drive.
The request for closing the drive switch means that the positioning serial port drive sends a request for closing the drive switch to the positioning system drive when the positioning serial port drive needs to close the positioning serial port drive. When the positioning system driver obtains the request for closing the driving switch, the positioning serial port driver is closed, and a driving closing completion instruction is sent to the positioning serial port driver after the positioning serial port driver is closed. After the positioning serial port driver is closed, the positioning serial port driver can no longer receive positioning data.
In the process of closing the positioning serial port drive, the host computer is required to call a sub-function ioctl _ gnss _ send _ drivercommand gnss _ setmemalogging gnss _ nmeastrem _ stop of the DeviceIOControl to generate a request for closing the drive switch.
In this embodiment, the request for turning off the driving switch is sent to the positioning system driver through the positioning serial port driver, and the positioning system driver turns off the positioning serial port driver, so that the positioning serial port driver can be in a turned-off state when not working, and the operation burden and the power consumption of the computer can be reduced.
In one embodiment, after the location serial driver stores the location data received from the location system driver in the buffer, the method further includes:
and the positioning serial port driver reports the positioning data received from the positioning system driver to the positioning application program at preset intervals.
The preset period can be set manually, and the period length can be 1S or other values.
Specifically, the positioning application program obtains the positioning data, and may actively issue the request for obtaining the positioning data of the buffer area as described above. Or the positioning serial port driver can upload the acquired positioning data to the positioning application program at preset intervals.
In this embodiment, the positioning data is reported to the positioning application program through the preset interval period of the positioning serial port driver, so that the positioning application program can continuously obtain displayable positioning data.
