Problems solved by technology

Then in this kind of network environment, it will appear that when the network environment is in good condition, the communication quality is good at this time. Since the data that can be transmitted in a fixed unit time is also fixed, the communication capability of the network is not fully utilized, resulting in network failure. The waste of resources, which is very prominent in the transmission of large data, increases the time of data transmission and reduces the user experience

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 The working model of the entire TDMA Internet of Things network is shown. TDMA gateways and TDMA devices run on hardware based on the WiFi platform, so the TDMA network inherits the characteristics of wide bandwidth of the WiFi network, and is faster than ZigBee and Z-wave in unit time. Traditional IoT is capable of transmitting larger data volumes. The TDMA Internet of Things protocol in the embodiment of the present invention only uses the hardware platform in the existing WiFi network, and the software protocol is a new design, which has no intersection with the existing WiFi protocol.

[0032] The TDMA Internet of Things protocol of the present invention runs between the TDMA gateway and the TDMA device, and the traditional HTTP protocol runs directly between the TDMA gateway and the router. The TDMA gateway sends...

Abstract

The invention provides a high-speed data transmission method for TDMA (Time Division Multiple Address) auto-negotiation rate. The method comprises the following steps: a TDMA gateway sends beacon messages to TDMA devices at a predetermined time interval; after receiving the beacon message, the TDMA devices immediately send keepalive messages to the TDMA gateway; the TDMA gateway checks the correctness of each frame of the keepalive messages in a unit time, and counts the bit error rate of the communication data between the TDMA gateway and the TDMA devices in real time; the TDMA gateway countsthe number of the keepalive messages sent by each TDMA device in the TDMA gateway per unit time, and calculates the packet loss rate of the network at this time; when receiving the keepalive messagesof the TDMA devices, the TDMA gateway reads the signal strength indicator RSSI of each keepalive message; the current communication quality of the network is evaluated; and the communication rate isadjusted. The method can not only improve the ability of the network to transmit big data, but also ensure the stability and reliability of the network.

Description

technical field [0001] The invention relates to the technical field of TDMA data transmission, in particular to a high-speed data transmission method based on WIFI hardware platform TDMA auto-negotiation rate. Background technique [0002] With the development of the Internet of Things and smart homes, the traditional IEEE 802.11 wireless LAN WiFi, because of its multiple access protocol based on the CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance) carrier sense multiple access / collision avoidance mechanism, because The network is complex, the system resources are more occupied, the protocol stack is complex, the development cycle is long, the product needs to be certified by the WiFi Alliance, and the number of sub-devices that can be carried by a network node is limited (for example, a router can carry dozens of mobile phones or PCs or other wireless AP). At the same time, most of the WiFi protocol patents are occupied by European and American countries, a...
