Problems solved by technology

Because of the commonly used wireless band signals, the coverage is limited, and it is impossible to be fully covered by a transmitting signal source
However, the wireless transmission in the same band can only have one transmission source, and multiple simultaneous transmission signals will cause serious interference.
Sending signals one by one can not accurately realize the synchronous flashing of the light groups, which adds great difficulties to this work

specific Embodiment approach

[0014] Specific implementation method: a method for synchronous flashing of a fog area induction lamp network, which is applied in a fog area induction lamp group, and the fog area induction lamp group includes several fog area induction lamps; each fog area induction lamp has With independent wireless receiving and wireless transmitting devices, the method of synchronous flashing of fog area induction lights in the same group is as follows:

[0015] a. Starting from the signal source, number the induction lights in the fog area one by one, numbering 1, 2, 3..., n,..., m lights one by one; it is possible to mark the sequence of each induction light.

[0016] b. Set the signal source to transmit wireless signals with delay time x, and the signal delay compensation time v between each adjacent lamp; set the group of lamps to receive and transmit wireless signals in sequence according to the number;

[0017] c. When the signal from the transmitting source can be received, the No....

Abstract

The invention belongs to the technical field of wireless communication and relates to a wireless ad hoc network signal synchronous control method, in particular to a fog area induced lamp networking synchronous flickering method. The method is applied in a fog area induced lamp set comprising multiple fog area induced lamps. Each fog area induced lamp is provided with an independent wireless receiving and wireless emission device. The synchronous flickering method for the fog area induced lamps in the same set includes the steps that the induced lamps are sequentially numbered as 1, 2, 3,..., n,..., m; a wireless signal of signal source emission delay time x and signal delay compensation time v are set; the wireless signal is received and emitted according to the numbers in sequence; when the signal received by mth lamp for the first time is the signal emitted by the nth lamp, the mth lamp flickers after delay time (x-n)*v; each induced lamp only receives the first-time signal. The method is simple in setting, free of signal interference and good in synchronization effect.

Description

technical field [0001] The invention relates to the technical field of wireless communication, and relates to a control method for signal synchronization of a wireless ad hoc network, in particular to a method for synchronous flashing of a network of induced lamps in foggy areas. Background technique [0002] When setting the fog area induction lights on the expressway, because the general expressway is set far from the town, the power supply is inconvenient. In order to save money, each induction light set up is powered by an independent solar cell and connected to each other through a wireless signal. Set up one or more groups of fog induction lights on a roadside, in order to enable them to flash synchronously, complex signal settings are required. Because of the commonly used wireless band signals, the coverage is limited, and it is impossible to be fully covered by one transmitting signal source. However, there can only be one source for wireless transmission in the s...
