Among them, mobile phones are connected to power data collectors through Bluetooth, such as infrared meter reading, dock scanning, and RFID, which have become an important form of operation terminals in the field of smart grid data collection, called split mobile operation terminals. The above-mentioned Bluetooth connection has high security requirements. Bluetooth communication requires devices to use "authentication" for security protection before the link is established, and data encryption can be performed at the application level after the link is established. Pairing is a key step before authentication. When pairing, the slave Bluetooth device must be in an open pairing state, which is vulnerable to attacks and leaks important information such as the device's PIN code. Therefore, the Bluetooth pairing link is an important link to ensure the safety performance of the entire system.

具体实施方式detailed description
下面结合具体实施例对本发明进行进一步描述，但本发明的保护范围并不仅限于此：The present invention is further described below in conjunction with specific embodiment, but protection scope of the present invention is not limited thereto:
实施例：如图1所示，一种用于可分离式移动作业终端的蓝牙安全配对方法，应用于手机1与电力行业智能电网数据采集器2的蓝牙配对。如图2所示，采集器2设计有蓝牙配对键。当按下时，将开关状态信号发送给主控芯片，主控芯片发送AT指令给蓝牙模块，蓝牙模块打开开放配对，控制发射功率为小功率状态。手机1与采集器2距离小于10CM可以进行通信，手机1作为蓝牙主设备发起配对扫描，采集器2作为蓝牙从设备应答扫描，手机1显示采集器2蓝牙名称。点击名称发起配对请求，采集器2蓝牙应答配对请求，同时将PIN码自动发给蓝牙主设备。蓝牙主设备弹出带有PIN码的配对确认信息，点击确认完成配对。蓝牙配对键关闭，配对采集器关闭蓝牙开放配对，功率设置为大功率。Embodiment: As shown in FIG. 1 , a Bluetooth security pairing method for a detachable mobile operation terminal is applied to the Bluetooth pairing between a mobile phone 1 and a smart grid data collector 2 in the electric power industry. As shown in Figure 2, the collector 2 is designed with a Bluetooth pairing key. When pressed, the switch status signal is sent to the main control chip, and the main control chip sends an AT command to the Bluetooth module, and the Bluetooth module turns on the open pairing, and controls the transmission power to a low power state. Mobile phone 1 and collector 2 can communicate if the distance is less than 10CM. Mobile phone 1 initiates a pairing scan as a Bluetooth master device, collector 2 responds to the scan as a Bluetooth slave device, and mobile phone 1 displays the Bluetooth name of collector 2. Click the name to initiate a pairing request, and the collector 2 Bluetooth responds to the pairing request, and at the same time automatically sends the PIN code to the Bluetooth master device. The Bluetooth master device pops up a pairing confirmation message with a PIN code, click OK to complete the pairing. The Bluetooth pairing key is turned off, the pairing collector is turned off and the Bluetooth is open for pairing, and the power is set to high power.
采集器2内的蓝牙模块自带有数控衰减电路，用来调节蓝牙功率为大功率状态与小功率状态。小功率状态下，手机1与采集器2在无干扰环境下，保持10CM距离，不断减小信号强度，使蓝牙通信的误码率小于90％，此时采集器2与手机1的通信距离为小于10M。The bluetooth module in the collector 2 has its own digital control attenuation circuit, which is used to adjust the bluetooth power to high power state and low power state. In the low-power state, the mobile phone 1 and the collector 2 keep a distance of 10 cm in a non-interference environment, and continuously reduce the signal strength, so that the bit error rate of Bluetooth communication is less than 90%. At this time, the communication distance between the collector 2 and the mobile phone 1 is Less than 10M.
采集器2内的蓝牙模块通过内部指令打开或关闭开放扫描，采集器2作为从蓝牙设备，打开开放配对可被主蓝牙设备扫描到，关闭开放配对，无法被主蓝牙设备扫描到。The Bluetooth module in the collector 2 enables or disables open scanning through internal commands. As a slave Bluetooth device, the collector 2 can be scanned by the master Bluetooth device when the open pairing is turned on, and cannot be scanned by the master Bluetooth device when the open pairing is turned off.
如图3所示的数控衰减电路，控制发射功率为小功率状态，A管脚的电压大于B管脚，即模拟开关U1正向偏置。信号传输给数控衰减U2，由天线T1发射。控制发射功率为大功率状态，B管脚的电压大于A管脚，即模拟开关U1反向偏置。信号由天线T2发射。The numerically controlled attenuation circuit shown in Figure 3 controls the transmission power to be in a low power state, and the voltage of the A pin is greater than that of the B pin, that is, the analog switch U1 is forward biased. The signal is transmitted to the digitally controlled attenuator U2 and transmitted by the antenna T1. The transmission power is controlled to a high power state, and the voltage of the B pin is greater than that of the A pin, that is, the analog switch U1 is reverse-biased. The signal is transmitted by antenna T2.
通过调节数控衰减U2的V1到V5脚的偏置电压来调节衰减值的大小，高电压为0，低电压为1，调节范围为二进制00000到111111，即0DBM到31DBM。手机1与采集器2在无干扰环境下，保持10CM距离，不断减小信号强度，使蓝牙通信的误码率小于90％，此时采集器2与手机1的通信距离为小于10M。The attenuation value can be adjusted by adjusting the bias voltage of the V1 to V5 pins of the digital control attenuation U2, the high voltage is 0, the low voltage is 1, and the adjustment range is binary 00000 to 111111, that is, 0DBM to 31DBM. The mobile phone 1 and the collector 2 keep a distance of 10CM in a non-interference environment, and continuously reduce the signal strength, so that the bit error rate of Bluetooth communication is less than 90%. At this time, the communication distance between the collector 2 and the mobile phone 1 is less than 10M.
以上的所述乃是本发明的具体实施例及所运用的技术原理，若依本发明的构想所作的改变，其所产生的功能作用仍未超出说明书及附图所涵盖的精神时，仍应属本发明的保护范围。The above descriptions are the specific embodiments of the present invention and the technical principles used. If the changes made according to the conception of the present invention do not exceed the spirit covered by the description and accompanying drawings, they should still be Belong to the protection scope of the present invention.
