Detailed Description
The following description is presented to disclose the invention so as to enable any person skilled in the relevant art to practice the invention. The embodiments described below are intended to be examples only, and other obvious modifications will occur to those skilled in the relevant art and are within the scope of the invention.
In one embodiment, the invention provides a non-inductive information acquisition method based on android bluetooth SPP. The method comprises the following specific steps:
step 1, acquiring equipment information in a range, and searching the equipment information by reading equipment in a broadcast mode;
the reading equipment uses a register receiving register receiver to register and receive BroadcastReceiver to acquire the Bluetooth state, equipment information and the like of the equipment to be read in a signal range;
firstly, detecting whether the Bluetooth of a read device is started; if the Bluetooth module is started, the Bluetooth module on the read equipment is directly connected; if not, reminding the user to start the Bluetooth;
step 2, establishing SPP connection, and acquiring the name and MAC address information of the equipment through the SPP connection;
the reading device uses BlueAdatper to search for a read Bluetooth device; acquiring the searched Bluetooth equipment name and MAC address information in onReceive of BroadcastReceiver;
step 3, establishing an object through the obtained MAC address, and preparing a connection interface to connect the Bluetooth equipment;
establishing a Bluetooth device object through the MAC address of the device; deriving a Bluetooth SOCKET from the Bluetooth device, and preparing a SOCKET to read and write the device; selecting a connected protocol and service by a createRfcommSocketToServiceRecord method of Bluetooth socket, reading a UUID of the equipment and confirming the uniqueness of the equipment;
step 4, reading the user health information of the Bluetooth equipment through the connection interface, and writing the user health information into a database;
after the reading device and the read device are connected, using getInputStream and getOutputStream of Bluetooth socket to read the user health information of the Bluetooth device, and writing the read user health information into the database,
step 5, comparing the data, and feeding back the result through a physical signal system;
and comparing the written user health information with the existing white list/black list database information, and feeding back the database record comparison result through a physical signal system to prompt the access right verification result of the personnel.
The invention is improved according to the practical problems in the use of the current health two-dimensional code, and can overcome the defects that the two-dimensional code is low in scanning speed and is easily influenced by the outside and a user in the practical use process. Through adopting the information acquisition based on tall and erect bluetooth SPP of ann, use bluetooth near field communication information acquisition technique, make the collection process reach the noninductive effect that just passes through entrance guard fast.
As shown in fig. 1, the specific practical process is as follows:
s1: a person carries a smart phone with Bluetooth in an open state to enter a security inspection channel of a certain subway station.
S2: the Bluetooth information reading device arranged at the security check searches nearby read devices through the BlueAdatper.
S3: after the read device is found, SPP connection is established through BroadcastReceiver, and then the searched device name and MAC address basic information of the Bluetooth device information are obtained through the read onReceive.
S4: a bluetooth device object is created in the system by reading the MAC address of the device.
S5: and deriving a Bluetooth socket through the established Bluetooth device object, and preparing a data interface Bluetooth socket to read and write the Bluetooth device.
S6: selecting a connection method through a createRfcommsocketToServiceRecord method of Bluetooth socket to select a connected protocol and service, and reading a UUID of the device to confirm the uniqueness of the device;
