The most common data transmission method today is WIFI data transmission, which is most well known.

Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Example 1:
Referring to fig. 1, fig. 1 of the present invention shows an overall method flow chart of the present invention.
Specifically, the system flow of the invention is as follows:
the internet of things connects all intelligent devices (intelligent wireless routers, intelligent mobile phones, intelligent PADs and the like) in one network domain, the intelligent internet of things link system is started, and the intelligent devices start to be powered on.
The first module is used for detecting the channel condition of the intelligent equipment in the Internet of things link system:
The total number of channels of each intelligent device in the 2.4G working frequency band is 13 no matter which data transmission mode, and the total number of channels of each intelligent device in the 5G working frequency band in the wireless WIFI data transmission mode is 5.
The intelligent device has 2 kinds of working frequency bands for wireless WIFI data transmission mode: the smart phone can only operate in the 2.4G operating band, and can operate in the 2.4G operating band and the 5G operating band, for example, in the following assumption that the smart phone can operate in the 2.4G operating band and the 5G operating band. The working frequency band of the intelligent device in the wireless ZigBee data transmission mode is only 2.4G, and the working frequency band of the intelligent device in the wireless Bluetooth data transmission mode is only 2.4G.
In the first mode, the intelligent link system detects the condition of idle channels under two different data transmission modes of the 2.4G working frequency band:
After the intelligent device starts to power on by 10MIN (the power on operation is performed after the data transmission), the intelligent Internet of things link system sends a piece of information to all intelligent devices which work on power on, an idle channel of the intelligent device can receive the information (an occupied channel can not receive the information) and responds to the intelligent Internet of things link system, the intelligent Internet of things link system divides a wireless data transmission mode of a 2.4G working frequency band into wireless WIFI and wireless ZigBee according to the response time (the time of responding to the Internet of things link system firstly is the standard, the 2S internal response after the standard is the time fault tolerance difference, the data transmission modes of the intelligent devices are all the data transmission modes of the wireless WIFI, the data transmission mode of the intelligent devices responding in the 2S after exceeding the standard is the wireless ZigBee), and meanwhile, the idle channels of the intelligent devices transmitting the data in the two modes are respectively numbered, and the number of the idle channel transmitting the data through the wireless WIFI and the name of the intelligent device are stored in a first temporary storage area of the intelligent Internet of things link system; and the number of the idle channel for data transmission through the wireless ZigBee and the name of the intelligent equipment are stored in a second temporary storage area of the intelligent Internet of things link system.
In one embodiment, assume that: in the first temporary storage area: and in the 2.4G working frequency band, the data transmission mode is wireless WIFI. Intelligent device name 1: smart phone, idle channel number of smart phone: SJ03, SJ04, SJ08, a total of 3 idle channels. Intelligent device name 2: intelligent PAD, idle channel number of intelligent PAD: PAD01 and PAD05 have a total of 2 idle channels. In the second temporary storage area: in the 2.4G working frequency band, the data transmission mode is wireless ZigBee. Intelligent device name 1: an intelligent electric lamp. Idle channel number of intelligent lamp: DD03, DD05, DD09, DD10, DD13, a total of 5 free channels. Intelligent device name 2: intelligent curtain. Idle channel number of intelligent curtain: DD01, DD02, DD06, a total of 3 idle channels.
And the intelligent Internet of things link system enters a mode II in 1S after the mode I is ended.
Mode two, the intelligent link system detects the condition of idle channels in the 5G working frequency band in a wireless WIFI data transmission mode:
The intelligent internet of things link system sends a piece of information to all intelligent devices working on electricity, idle channels of the intelligent devices can receive the information and respond to the intelligent internet of things link system, response time is faster than standard time in mode one and is the intelligent devices in the 5G working frequency band, and idle channel numbers of the intelligent devices and names of the intelligent devices are stored in a third temporary storage area of the intelligent internet of things link system.
In one embodiment, in the third register: and in the 5G working frequency band, the data transmission mode is wireless WIFI. Intelligent device name 1: smart phone, idle channel number of smart phone: SJ14 and SJ15 have 2 idle channels in total. Intelligent device name 2: intelligent TV, idle channel number of intelligent TV: the TV14, TV16, TV18 have a total of 3 idle channels.
And the intelligent Internet of things link system enters a mode III in 1S after the mode II is ended.
Mode three, the intelligent link system predicts whether the idle channels will have channel blocking when transmitting data according to the number of data bars to be transmitted later:
The intelligent internet of things link system acquires the number of transmission data strips, after 1S, the intelligent internet of things link system calculates the occupied amount z of the transmission data strips = the number of the transmission data strips/the total idle channel number (the total idle channel number = the sum of the idle channels of the mode one and the mode two), if the occupied amount z of the transmission data strips is more than or equal to 30%, the intelligent internet of things link system judges that channel blocking occurs, the occupied amount z of the transmission data strips is stored in a fourth temporary storage area of the intelligent internet of things link system, and meanwhile, a module two is started; if the transmission data strip is less than 30%, the module I is directly finished.
The intelligent internet of things link system calculates a module of idle factors:
Starting a module for calculating idle factors according to the condition of the mode three of the module I, and creating a thread 1:
The intelligent internet of things link system reads the value of the duty ratio z of the transmission data strip in the fourth temporary storage area, and enters a mode II when the value of z is more than or equal to 30% and less than or equal to 60%; mode one is entered when the value of z is greater than 60%.
Mode one, search for external intelligent device that carries out data transmission through wireless bluetooth connection:
The intelligent internet of things link system sends a command for starting wireless Bluetooth pairing, and simultaneously sends information of external intelligent equipment capable of pairing to the wireless Bluetooth. After 1S, the intelligent Internet of things link system sends a starting command to the external intelligent devices which can be paired but are not powered on. The wireless Bluetooth is successfully paired with the started external intelligent devices.
The intelligent internet of things link system obtains the names of the external intelligent devices successfully paired, numbers the idle channels in the 2.4G working frequency band according to the time of the successful pairing, stores the names of the external intelligent devices and the numbers of the idle channels in a seventh temporary storage area of the intelligent internet of things link system, and enters the second module.
In one embodiment, the external smart device 1: intelligent Bluetooth headset, external intelligent device 2: an intelligent desktop printer. The wireless Bluetooth is successfully paired with the intelligent Bluetooth headset at the 3S of the initial pairing and is successfully paired with the intelligent desktop printer at the 5S of the initial pairing. That means that the pairing time of the intelligent Bluetooth headset is prior to the intelligent desktop printer. Then the idle channel number of the smart bluetooth headset is LY01-LY13 and the idle channel number of the smart desktop printer is TD14-TD26.
Mode two, the intelligent internet of things link system calculates idle factor values in a 2.4G working frequency band in a wireless WIFI data transmission mode:
since the most common data transmission mode nowadays is wireless WIFI data transmission, the total number of idle channels and the total number of intelligent devices in the first temporary storage area of the intelligent devices in the 2.4G working frequency band cannot be empty.
The intelligent internet of things link system reads the total idle channel number and the total intelligent device number of the intelligent devices in the 2.4G working frequency band in the first temporary storage area, and then calculates idle factor k=total idle channel number/total channel number.
In one embodiment, assume that: if the total number of idle channels in the first temporary storage area in the mode one of the first module is 3+2=5, the total number of intelligent devices is 2. Since the total number of channels per smart device is 13 in either data transmission mode in the 2.4G operating band, the total number of channels is 13×2=26. Then the idle factor k1=5/26.
And storing the value of the idle factor k into a fifth temporary storage area of the intelligent Internet of things link system, and entering a mode III.
Mode three, the intelligent internet of things link system calculates idle factor values in a 2.4G working frequency band in a wireless ZigBee data transmission mode:
And the intelligent internet of things link system reads the total idle channel number and the total intelligent equipment number of the intelligent equipment in the 2.4G working frequency band in the second temporary storage area, and if the information in the second temporary storage area is empty, the idle factor R=0 and directly enters the third module. If the information in the second temporary storage area is not empty, the intelligent internet of things link system calculates an idle factor R=total idle channel number/total channel number.
In one embodiment, the total number of idle channels in the second buffer is 5+3=8 and the total number of smart devices is 2 in mode one of the first module. Because the total number of channels of each intelligent device in the 2.4G working frequency band is 13 in the wireless ZigBee data transmission mode, the total number of channels is 13×2=26. Then the idle factor r1=8/26.
And storing the value of the idle factor R into a sixth temporary storage area of the intelligent Internet of things link system, and entering a third module.
The third module is a module for dynamically distributing idle channels for data transmission by the Internet of things link system:

in the first mode, an intelligent Internet of things link system dynamically allocates an idle channel of an intelligent device with a working frequency band of 5G in a wireless WIFI data transmission mode to perform data transmission;
And the intelligent internet of things link system reads the total idle channel number and the total intelligent equipment number of the intelligent equipment with the working frequency band of 5G in the third temporary storage area in the wireless WIFI data transmission mode, and directly enters the second module.
And the intelligent Internet of things link system reads the total idle channel number and the total intelligent equipment number of the intelligent equipment with the working frequency band of 5G in the third temporary storage area in the wireless WIFI data transmission mode, and the total idle channel number and the total intelligent equipment number are not empty. The intelligent internet of things link system randomly selects intelligent equipment with a working frequency band of 5G in a wireless WIFI data transmission mode, and then data to be transmitted are transmitted according to the sequence of idle channel numbers.
In one embodiment, assume that: the intelligent equipment randomly selected by the intelligent internet of things link system is a smart phone, and the idle channel number of the smart phone in the first temporary storage area is as follows: SJ14, SJ15, then data is transmitted over the free channel SJ14 and then one piece of data is transmitted over the free channel SJ 15. After all idle channels of the intelligent mobile phone are occupied to transmit data, the intelligent Internet of things link system randomly selects the next intelligent device, and data transmission is performed again according to the method.
When the idle channels of the intelligent device with the working frequency band of 5G are occupied in the wireless WIFI data transmission mode, data are still not transmitted, and then the mode II is entered.
In the second mode, the intelligent Internet of things link system dynamically allocates an idle channel of the intelligent equipment with the working frequency band of 2.4G for data transmission;
The intelligent internet of things link system reads the value of the idle factor k in the fifth temporary storage area and the value of the idle factor R in the sixth temporary storage area, compares the values of the idle factors, and if the values are large, the idle channel in the data transmission mode is preferentially used for data transmission, and if the idle channel is insufficient, the idle channel in the other data transmission mode is used for data transmission.
In an embodiment, if the value of the idle factor k is greater than the value of the idle factor R, then the idle channel of the intelligent device with the working frequency band of 2.4G in the wireless WIFI data transmission mode is preferentially used for data transmission, and the data transmission mode is the same as the mode one of the three modes of the module. When the idle channels of the intelligent devices are not enough, the idle channels of the intelligent devices with the working frequency band of 2.4G in the wireless ZigBee data transmission mode are used for data transmission, and the data transmission mode is the same as the mode one of the three modes of the module.
When the idle channels of the intelligent device with the working frequency band of 2.4G are occupied, data are still not transmitted, and then the mode III is entered.

And the intelligent internet of things link system reads the numbers of the idle channels in the seventh temporary storage area, and then performs data transmission according to the sequence of the numbers of the idle channels.
In one embodiment, assume that: the idle channel number of the intelligent Bluetooth headset is LY01-LY13, and the idle channel number of the intelligent desktop printer is TD14-TD26. Data is transmitted through the idle channel LY01, and then one piece of data is transmitted through the idle channel LY 02.
When the idle channels of the external intelligent equipment with the working frequency band of 2.4G are occupied in the wireless Bluetooth data transmission mode, data are still not transmitted, and then the following operation is carried out again by the slave module. (that is, the intelligent devices of which working frequency band is in whatever data transmission mode, all the idle channels are occupied, and the following data transmission operation can not be performed until the idle channels exist, namely, the intelligent devices restart from the module)
