Problems solved by technology
In this way, when detecting the control signal, if the master terminal transmits the control signal through the first channel, but the controlled terminal detects whether there is the control signal one by one from the second channel, the controlled terminal cannot receive the control signal immediately. The control signal must wait for all channels to be detected, and then re-detect the second channel to receive the control signal, causing the controlled terminal to delay action

Embodiment Construction
[0025] The technical means adopted by the present invention to achieve the intended purpose are further described below in conjunction with the accompanying drawings and preferred embodiments of the present invention.
[0026] The invention provides a wireless signal unidirectional frequency hopping transmission method, and the transmission method is executed by a main control terminal. The sending method includes a sending step.
[0027] see figure 1 As shown, the transfer step includes the following sub-steps:
[0028] A plurality of channels are preset, and each channel has a corresponding environmental noise intensity S10;
[0029] Select a channel from the channels whose ambient noise intensity is lower than a critical value and set it as the channel S11;
[0030] Detecting the actual environmental noise intensity of the used channel at a first time S12;
[0031] Judging whether the actual environmental noise intensity of the used channel is lower than the critical v...

The present invention provides a wireless signal one-way frequency hopping transmitting method and a receiving method thereof. The transmitting method includes a detection program and a transmitting program. According to the transmitting method, the transmitting program rapidly detects environmental noises of a using channel with a first time when transmitting a control signal, and the detection program detects environmental noise intensities of all channels with a second time longer than the first time and stores the environmental noise intensities of the channels for next-time usage of the transmitting program, thereby reducing delay time caused by detection by the transmitting program, thus to meet requirements for rapid response. According to the receiving method, a channel previously receiving the control signal is stored as a priority channel, and the priority channel is preferentially detected, thereby raising the probability of receiving the control signal, further reducing the delay time and meeting requirements of rapid response.
Description
technical field [0001] The invention provides a one-way frequency hopping technology, especially a transmission method for one-way frequency hopping of wireless signals. Background technique [0002] Generally, when performing remote control through wireless signals, a master control terminal transmits a signal to a controlled terminal, and the master control terminal can transmit signals through wireless signals to control the controlled terminal. For example, the main control terminal is a remote control of the iron rolling door, and the controlled end is an iron rolling door with a wireless signal receiver, the user can directly operate the iron rolling door remote control to control the opening and closing of the iron rolling door . However, the wireless signal remote control transmits the wireless signal signal at a specific frequency. When the noise at the specific frequency in the environment is too large, the environmental noise will inevitably affect the transmissi...
