The disclosure relates to a control method for performing rapid connection and data transmission between devices.
At present, a wireless short-range communication technology may be used for data communications between devices. Application of a wireless short-range communication module (e.g., Bluetooth module, ZigBee module and WIFI module) to various devices solves the troubles of wiring to make it convenient and fast. However, as the wireless short-range communication technology is applied more and more widely, the defects of the wireless short-range communication technology in actual use is exposed. As shown in
Due to restriction to the abovementioned operation, the utilization rate of the wireless short-range communication function is not high. For example, for Bluetooth connection, many users merely use Bluetooth earphones and seldom use Bluetooth to transmit data.
To sum up, the wireless short-range communication function, such as a Bluetooth function, adopted on the terminal device in the conventional art is relatively complicated in terms of starting, closing and pairing operations. As a result, many users are not willing to use wireless short-range communication modules for communications between devices. Moreover, it is necessary to manually select a sensor device data type on the user interface of the master device, so the operation process is complicated. Thus, there is a demand for a safe and easy-to-use control method for performing rapid connection and data transmission between devices without manually starting a wireless short-range communication function (e.g., Bluetooth and WIFI functions), manually inputting verification information (e.g., Bluetooth and WIFI user verification codes), manually selecting a sensor device data type on a user interface of a master device, and manually matching.
For one of the technical problems to be solved, the disclosure provides a safe and easy-to-use control method for performing rapid connection and data transmission between devices without manually starting a wireless short-range communication function (e.g., Bluetooth and WIFI functions), without manually inputting verification information (e.g., Bluetooth and WIFI user verification codes) and without manually inputting type information about a connected sensor device, thereby omitting the process of manual matching and manual input.
To solve the abovementioned technical problems, the disclosure provides several relevant technical solutions as follows. A control method for performing rapid connection and data transmission between devices is characterized by including: writing, by a Radio Frequency Identification (RFID) reader and writer module, relevant information, such as address information and sensor device type information, about a wireless short-range communication module in a slave device (sensor device) into an RFID label, or printing, by a bar code printer, the relevant information into a bar code label; and fixing the RFID label or the bar code label onto the sensor device; and reading, by the RFID reader and writer module or a bar code reader in the master device (terminal device), information from the RFID label or from the bar code label; starting a function of the wireless short-range communication module according to the read information; automatically matching relevant information (e.g., secret key), and popping up a corresponding user interface according to the obtained sensor device type information to display collected data.

Step 2: when it is necessary to acquire data information about the sensor device, reading information from the RFID label by using an RFID function of a terminal device, to acquire information about the wireless short-range communication module such as the MAC address of Bluetooth or WIFI SSID and secret key information and sensor device type information; judging a used communication mode from the read information; when a Bluetooth function is used, automatically starting, by the terminal device, a Bluetooth module, searching for a Bluetooth module with the corresponding name; after the Bluetooth module is found, performing Bluetooth pairing by automatically inputting the read secret key information; and after pairing is successful, sending a command to establish a connection; and when the read information indicates that the sensor device is connected through WIFI, automatically connecting the terminal device to an SSID of the corresponding wireless local area network and inputting the read secret key information; and after the connection to the SSID of the wireless local area network is successful, automatically connecting client software on the terminal device to the sensor device to acquire data from the sensor device; and
Step 3: after the connection is established, automatically selecting and entering, by the terminal device, an application interface (e.g., temperature collection interface) for the sensor device according to the sensor device type information (e.g., thermometer) acquired from the RFID label; when the sensor device acquires sensing data (e.g., body temperature of a patient), automatically uploading the sensing data to the application interface (e.g., temperature collection interface) for the sensor device of the terminal device through the wireless short-range communication connection that is already established; and if necessary, uploading the sensing data to a remote background server (e.g., data center) through a wireless local-area or wide-area module of the terminal device.
As an improvement, after the Step 3, the method further comprises: Step X, maintaining the established data link, until the terminal device starts to read the RFID label for next time (that is, before establishing a new wireless short-range communication connection); and when the link is broken, automatically re-establishing the connection according to the Bluetooth MAC address or the SSID and the secret key of the wireless local area network; or Step Y, when data transmission is completed and the connection needs to be disconnected, clicking, by a user, an off key on a user operation interface to switch off a Bluetooth or WIFI device; or, after the terminal device is screen-off, entering a power-saving mode or automatically disconnecting the connection of the wireless short-range communication module, and after the terminal device is screen-on, re-establishing the connection.

The disclosure will be further illustrated in detail hereinbelow with reference to the drawings.
A control method for performing rapid connection and data transmission between devices will be illustrated in
Step 1: Information about a wireless short-range communication module, such as an MAC address of a Bluetooth module or a WIFI wireless network SSID and a secret key are written into a label by an RFID reader and writer module. And a serial number and type information of the sensor device is also written into an RFID label by the RFID reader and writer module. When a bar code label is fixed onto the sensor device, the above information is encoded and printed into a bar code by a bar code printer. The RFID label or the bar code label is fixed onto the sensor device for convenience of identification of a terminal device.
Step 2: When it is necessary to acquire data information about the sensor device, and if the RFID label is used on the sensor device, label information is read by using an RFID function of the terminal device to acquire MAC address or WIFI SSID name and secret key information. A used wireless short-range communication mode is determined from the information which is read from the RFID label. When a Bluetooth function is used, the terminal device automatically starts a Bluetooth module and searches for a Bluetooth module with the corresponding name. After the Bluetooth module is found, Bluetooth pairing is performed. The secret key information is automatically input in this process. After pairing is successful, a command is sent to establish a connection. When the bar code label is used on the sensor, the terminal device starts a bar code reader and reads information from the bar code label. The processes of Bluetooth pairing and connection establishment are the same as the processes mentioned above. When the acquired information indicates that the sensor is connected through WIFI, the terminal device is automatically connected to an SSID of the corresponding wireless local area network and inputs the secret key information. After the connection to the SSID of the wireless local area network is successful, client software on the terminal device will be automatically connected to the sensor device to acquire data from the sensor device.
Step 3: After the connection is established, the terminal device sends a command to the sensor device. The sensor device returns the collected data information to the terminal device. The data information contains device information of a certain frame format. The terminal device compares the device information with the device information obtained previously. When the comparison result indicates that the information is correct, a corresponding interface is entered according to a device type for user operations. For example, when temperature information is to be presented, a temperature interface is popped up, and when blood pressure information is to be presented, a blood pressure interface is popped up.
Step 4: An established data link will be maintained and the terminal device will send a command regularly to obtain data, until the terminal device starts to scan by using the RFID reader and writer module or the bar code reader for a next time. When the link is disconnected, the connection will be automatically re-established according to the Bluetooth MAC address or the SSID of the wireless local area network and the secret key.
Step 5: When data transmission is completed, the connection may be disconnected for saving power. A user only needs to click an off key on a data operation interface to switch off the wireless short-range communication module. After the terminal device is screen-off, a power-saving mode is entered or the wireless short-range communication module is automatically disconnected. After the terminal device is screen-on, the connection is re-established.
A control method for performing rapid connection and data transmission between devices is provided. When a sensor device has a wireless short-range communication function such as Bluetooth or WIFI, rapid connection and then rapid data transmission are implemented through an RFID label and a bar code label according to Steps 1 to 5. When a used sensor device does not have the wireless short-range communication function, the RFID label and the bar code label only contain device information, and after RFID label data or bar code label data is read, a system will automatically judge what the device is, and then enters a corresponding interface for convenience of user operations. For example, when blood pressure information is to be presented, a blood pressure information input interface is entered, and when blood glucose information is to be presented, a blood glucose information input interface is entered.
