Embodiment Construction

[0050] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments will be described in detail below together with the accompanying drawings.

[0051] see Figure 1A As shown, the figure is a schematic flow chart of an embodiment of the radio frequency channel determination method of the present invention. In this embodiment, the method 2 includes the following steps: first, perform step 20 to generate a random value. There are many ways to generate random numbers in common technologies, the way of the embodiment of the present invention can be seen Figure 1B shown. First, step 201 is performed to determine a random number seed. The random number seed can be determined by using the voltage value of the power supply in the transmitting end (a radio frequency wireless transmitting device in this embodiment) or the time signal generated by the timing element as the random number seed. Then proceed t...

Abstract

The present invention provides an RF channel deciding and conversing method. Communication channels can be automatically changed at random according to signal communication states; and thus, an emission end and a receiving end can be kept in communication states to ensure signal transmission. In another embodiment, the present invention also provides an RF wireless transmit-receive system. Channels mutually communicated between two wireless transmitting dies are automatically generated at random, and the RF wireless transmit-receive system has a function for preventing the channels from impaction to avoid channel repetition. In addition, the present invention has an automatic channel-jumping function for preventing data from losing and special codes for preventing the data from wrongly receiving to ensure that users can not have the condition of data receiving stop, mistake or lose in a using process.

Description

technical field [0001] The present invention relates to a radio frequency technology, in particular to a method for determining and changing a radio frequency channel and a radio frequency wireless transceiver system that can automatically and randomly generate a communication channel according to a communication state. Background technique [0002] When multiple people use wireless transmission devices in the same space at the same time, channel collisions may occur. Due to the advancement of technology, the surrounding living environment is full of computers, instruments, cables and other equipment, accompanied by various The interference of electromagnetic waves also causes the wireless transmission device to fail to use the channel normally during the data transmission process, resulting in the suspension of data transmission or reception error. [0003] In order to avoid the problem of data transmission or reception caused by signal interference, commonly used technolog...
