Problems solved by technology

[0003] The wireless frequency hopping network can resist external frequency interference very well through fast frequency switching, and also provides good communication security, but it also makes the process of wireless device access to the network complicated and time-consuming, resulting in on-site maintenance, equipment installation and adjustment. It is very inconvenient to perform tasks such as testing and other tasks that require quick confirmation and verification

Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as Figure 1 to Figure 4 As shown, a fast access method of a wireless frequency hopping network specifically includes the following steps:

[0028] 101) Step of broadcasting by the access requesting device: the access requesting device broadcasts the RTS to the user, and the RTS contains the broadcast value and is sent continuously. The PanID included in the RTS is a broadcast value, which allows any node in the network to respond. The RTS sending process lasts at least 64 time slots, that is, a complete access process needs 64*2*20ms=2560ms, and if the possibility of communication failure is not considered, the time consumption should not exceed 2560ms.

[0029] 102) In-network node unicast step: After receiving the broadcast RTS, the in-network node device sends a unicast RTS to the access requesting device in a competitive mann...

Description

technical field [0001] The invention relates to the network field, and more specifically, it relates to a fast access method for a wireless frequency hopping network. Background technique [0002] Frequency hopping technology is a commonly used anti-interference communication technology, which is often used in wireless networks that require high network robustness. During the operation of the wireless frequency hopping network, the working frequency of the wireless devices in the network is switched in units of time slices, and the frequency switching is performed in a predefined periodic sequence. [0003] The wireless frequency hopping network can resist external frequency interference very well through fast frequency switching, and also provides good communication security, but it also makes the process of wireless device access to the network complicated and time-consuming, resulting in on-site maintenance, equipment installation and adjustment. It is very inconvenient ...
