Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart of a POS data communication method according to an embodiment of the present invention, which includes the following steps:
s1, it is determined whether the POS terminal in the wireless network is connected for the first time.
It is understood that, before the step is performed, the POS card reader and the POS terminal are both in the on state, so that the POS card reader or the POS terminal can be searched in the wireless network. In this embodiment, the POS terminal is in a powered-on state, and the wireless network port thereof is opened, so that the POS card reader can search for the POS terminal in the wireless network. Preferably, in this embodiment, the wireless network is a bluetooth network. Further, after the POS terminal in the wireless network is searched, the POS card reader can acquire the equipment information of the POS terminal according to the searched POS terminal signal. The device information may include a name of the POS terminal, product serial number information, version number information, model number information, and the like. When the POS card reader acquires the equipment information of the POS terminal, any one of the information can be acquired, and multiple kinds of information can be acquired simultaneously. And the POS card reader confirms whether the system has a trace that the POS terminal is connected once or not according to the acquired equipment information. In this embodiment, the POS terminal and the POS card reader perform data communication via bluetooth. In a more preferred embodiment, the bluetooth module is disposed on a bluetooth base, and the bluetooth base is connected with the POS card reader to become a peripheral device of the POS card reader. The POS card reader is in Bluetooth data communication with the POS terminal through the Bluetooth base.
And S2, if the POS terminal is confirmed to be connected for the first time, receiving a pairing request from the POS terminal, and establishing connection with the POS terminal based on the pairing request.
In this embodiment, if no record consistent with the device information of the POS terminal is found in the POS card reader or the bluetooth base, it is determined that the POS terminal is connected for the first time. In this case, the POS card reader or the bluetooth cradle connected thereto cannot actively initiate a connection to the POS terminal, and the POS terminal is required to actively initiate a pairing request to the POS card reader. After the pairing is completed, the POS terminal is connected with the POS card reader, so that data communication can be carried out.
After the POS terminal connected for the first time completes data communication of a Bluetooth network with the POS card reader, the POS card reader or a Bluetooth base connected with the POS card reader confirms that the POS terminal is matched according to the matching request, and the matching request comprises the equipment information and the Mac address of the POS terminal. And after the pairing is completed, the POS card reader or a Bluetooth base connected with the POS card reader writes the equipment information and the Mac address into a prestored list of the Mac address. Therefore, the equipment information of the POS terminal connected with the POS card reader and the Mac address thereof are recorded in the storage unit of the POS card reader or the Bluetooth base connected with the POS card reader. The recorded POS terminal device information may be used to confirm whether the POS terminal is the first connection when the POS terminal is next searched.
And S3, if not, reading the pre-stored Mac address corresponding to the POS terminal from a pre-stored list of the Mac address, and establishing connection with the POS terminal according to the pre-stored Mac address.
In this embodiment, if a record that matches the device information of the POS terminal is found in the POS card reader or the bluetooth cradle connected thereto, it is determined that the POS terminal is not connected for the first time. And the POS terminal which is not connected for the first time indicates that the equipment information corresponding to the POS terminal can be found in the prestored list. And at the same time, there is a Mac address corresponding to the device information. At this time, the POS card reader may read a pre-stored Mac address corresponding to the POS terminal in a pre-stored list of Mac addresses, and establish a connection with the POS terminal according to the pre-stored Mac address. In this embodiment, when the POS card reader confirms that the POS terminal is not connected for the first time, it may actively initiate connection to a pre-stored Mac address corresponding to the device information according to the device information, and finally establish connection with the POS terminal.
For example, as shown in FIG. 4, in use, the POS terminal is connected to the Bluetooth cradle, while the Bluetooth cradle is connected to the POS swipe card reader. The POS card reader is connected with a Bluetooth module of the POS terminal through a Bluetooth base in a close-range Bluetooth mode. When the POS terminal is connected with the Bluetooth base for the first time, the POS terminal needs to initiate a pairing request to the Bluetooth base, and the Bluetooth connection between the POS terminal and the Bluetooth base can be realized only after the Bluetooth base confirms the pairing request. After a successful bluetooth connection, the bluetooth cradle records the Mac address of the POS terminal in its memory. The connection between the POS terminal and the bluetooth cradle is then broken because no connection is necessary, power is off, or other possibilities are possible. At this point, the pairing request no longer needs to be initiated by the POS terminal, but rather a bluetooth connection to the POS terminal can be initiated directly by the bluetooth cradle. Because the Mac address of the POS terminal is recorded in the memory of the Bluetooth base, the Bluetooth base can be directly connected with the POS terminal according to the Mac address. Through the connection design, the Bluetooth base can be quickly connected with the POS terminal, and the POS terminal does not need to initiate a pairing request every time, so that the operation of the POS terminal is greatly reduced.
In a second embodiment of the present invention, as shown in fig. 2 and 3, there is provided a POS data communication device 100, the device 100 including:
a determining module 110, configured to determine whether a POS terminal in a wireless network is connected for the first time;
a connection establishing module 120, configured to receive a pairing request from a POS terminal when it is determined that the POS terminal is connected for the first time, and establish a connection with the POS terminal based on the pairing request; or when the POS terminal is determined not to be connected for the first time, reading a pre-stored Mac address corresponding to the POS terminal from the Mac address pre-stored list, and establishing connection with the POS terminal according to the pre-stored Mac address.
Further, as shown in fig. 3, the connection establishing module 120 includes:
a pairing module 121, configured to confirm pairing with the POS terminal according to the pairing request; wherein the pairing request comprises equipment information and a Mac address of the POS terminal;
and the recording module 122 is configured to write the device information and the Mac address into a pre-stored list of Mac addresses.
