The BAN coordinator 120 is a network manager of the body area network and is also a gateway between the body area network and an external network, and the BAN coordinator enables data to be securely transmitted. The communication devices 110, the communication devices 110 and the BAN coordinator communicate with each other through bluetooth, wifi, ZigBee or other wireless methods.
Referring to fig. 2, fig. 2 is a flowchart of an information communication method of a body area network according to an embodiment of the present invention, which is described from the perspective of devices in the body area network, and the information communication method of the body area network includes steps S201 to S204.
In step S201, the first device receives a digital command sent by the second device to the body area network using the first frequency.
Specifically, the body area network comprises the first device and the second device, and the first device and the second device are connected in a Bluetooth, wifi, ZigBee or other wireless modes. After the second device sends the digital instruction to the body area network, the first device receives the digital instruction sent by the second device by using the first frequency regardless of whether the digital instruction is sent to the first device.
The first frequency is set manually and is different from a second frequency used for sending digital information later, and different frequencies are used for receiving and sending data respectively in the data transmission process, so that the data transmission is more accurate and reliable. In the body area network, all devices use a first frequency when receiving data and a second frequency when transmitting data.
In other embodiments, if the body area network further includes other devices, such as a third device and a fourth device, after the second device sends the digital command to the body area network, the first device, the third device, and the fourth device on the body area network all receive the digital command using the first frequency.
In step S202, it is checked whether the received digital command is a digital command sent by the second device to the first device.
Specifically, in this embodiment, the digital instruction includes a flag of a receiving party, and after the first device receives the digital instruction, the first device checks the flag included in the digital instruction, and if the flag is the flag of the first device, the digital instruction is the digital instruction sent to the first device. In other embodiments, the first device may also check whether the received digital instruction is a digital instruction sent by the second device to the first device by another way, which is not limited herein.
In step S203, if the received digital command is a digital command sent by the second device to the first device, the first device accepts the digital command.
In another embodiment, if the digital command received by the first device is not the digital command sent by the second device to the first device, the digital command is ignored.
In step S204, digital information is transmitted to the second device using a second frequency based on the digital instruction.
Specifically, after receiving the digital instruction, the first device sends digital information to the second device based on the digital instruction, where the digital information is a human health signal, an action signal, an environmental signal, or another type of signal acquired by the first device, and the digital information is converted into digital information, and then sent to the second device using a second frequency.
As can be seen from the above, in the body area network information communication method in the embodiment of the present invention, the first device receives all the digital instructions on the body area network, and then determines whether the digital instructions are sent to the first device, and if the digital instructions are sent to the first device, receives the digital instructions and sends digital information to the device that sends the digital instructions using the second frequency based on the digital instructions.
Referring to fig. 3, fig. 3 is a flowchart of another body area network information communication method according to an embodiment of the present invention. The information exchange method of the body area network comprises the steps S301-S306. It is understood that steps S202 to S204 in the embodiment shown in fig. 2 may also be applied to steps S304 to S306 in this embodiment, which is not described herein again.
In step S301, the first device receives a first digital command sent by the second device using a first frequency, and the first device simultaneously receives a second digital command sent by the third device using the first frequency.
In particular, devices within the body area network may send digital commands to the body area network at any time. In this embodiment, the second device sends a first digital command to the body area network, and the third device sends a second digital command to the body area network, and at this time, the other devices in the body area network all receive the digital command. The first device receives the first digital instruction and the second digital instruction at the same time, but the first device does not really receive the two digital instructions at the same time, and the first device executes the operation of step S302 to determine the priorities of the second device and the third device.
In step S302, the first device determines priorities of the second device and the third device.
Specifically, all devices in the body area network have different priorities, the priorities are self-defined or default priorities according to the needs of users, and when the same device receives digital instructions or digital information from different devices at the same time, the digital instructions or digital information from the devices with high priorities are received first. For example, in this embodiment, the second device has a first priority, the third device has a second priority, and the first priority is higher than the second priority, and when the first device receives the first digital instruction of the second device and the second digital instruction of the third device at the same time, the first device determines that the priority of the second device is higher than that of the third device.
In step S303, if the priority of the second device is higher than the priority of the third device, the first device continues to receive the first digital command sent by the second device through the first frequency, and the first device stops receiving the second digital command sent by the third device through the first frequency.
Specifically, in this embodiment, the first device receives the first digital command of the second device with a high priority, and receives the second digital command of the third device with a low priority after the first digital command is received.
In step S304, the first device determines whether the first digital command is a digital command sent by the second device to the first device.
In step S305, if the received first digital command is a digital command sent by the second device to the first device, the first device accepts the first digital command.
In step S306, the first device transmits digital information to the second device using a second frequency based on the first digital instruction.
In another embodiment, the body area network may further perform information communication with an external device. The external device may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID) or other terminal device. When the external device is connected with any one device in the body area network through the BAN coordinator in the body area network in a wireless mode, the external device can acquire digital information in any one device through the connection, and therefore information exchange between the body area network and the external device can be achieved.
As can be seen from the above, in the body area network information exchange method in the embodiment of the present invention, by first receiving the first digital command sent by the second device with the higher priority, and then determining whether the first digital command is sent to the first device, if the first digital command is sent to the first device, the information exchange method receives the first digital command and sends digital information to the equipment sending the digital command by using a second frequency based on the first digital command, the information exchange method respectively uses different frequencies to receive and send the digital command and the digital information, has strong anti-interference capability and high reliability and safety, when receiving data, the data is received before whether the data is sent to the data receiver or not, the operation is simple, each device in the body area network has different priorities, so that the requirement of real-time performance is met, and the user experience is improved.
