Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology applied in the fire protection industry, and more specifically, to a competition-based adaptive multi-channel wireless anti-interference communication method and system. Background Art

[0002] In order to solve the problem of wireless space communication channel utilization, traditional wireless communication networks solve this problem by allocating the time occupancy rate of the channel, that is, the network time allocation mechanism in which the host makes time division multiplexing for the slave, and allocates working time slices to the slave. The specific method is that after the slave first enters the network, the host calculates the slave's channel and channel occupancy rate, allocates the corresponding channel and time slice, and then generates a work configuration file and sends it to the slave, so that different slaves can work in different working time slices. The key lies in the effective use of channel time resources. At the same time, for the allocation of air interface channel resources, each slave will be fixed on the corresponding time slice of a channel.

[0003] However, this network allocation method is inefficient. On the one hand, each slave can only work in the corresponding polling time slice. If the transmission fails, it needs to wait for the next round of transmission time slice, which affects the timeliness of the alarm. On the other hand, it only considers the mutual time interference within the system, and does not consider the external environmental interference. When there is environmental interference, this transmission may fail. The core disadvantage is that the timeliness of the network is insufficient, and the fire warning alarm wireless network requires the timeliness of the alarm as the core. At the same time, this method of allocating air interface resources has inherent defects in anti-interference, because the channels and time slices it allocates are fixed and regular, and it does not have sufficient anti-interference ability when encountering regular interference.

[0044] The technical solution provided by the embodiments of the present invention may have the following beneficial effects:

[0045] The present invention is based on the time conflict mechanism. Before sending, the terminal or slave performs pre-sending listening detection, detects all modulated and non-modulated signals in the space, and performs appropriate detection and conflict avoidance. The network does not need to allocate time slices and communication channels. The gateway has multiple physical channels. The communication rates and communication parameters of each channel are different and form an orthogonal relationship. When the terminal or slave first accesses the network, the gateway sends down its communication channel frequency, communication rate, bandwidth, modulation mode and other information. When the terminal communicates, it defaults to communicating from a high-speed channel. After a communication failure caused by, for example, mutual interference and collision within the same system or interference from different systems or environmental influences, it communicates from a lower-speed channel.

[0046] The present invention reduces the demand for the accuracy of the terminal's clock hardware. Through the gateway multi-channel, the slave machine can adapt to multi-channel communication through a conflict mechanism to solve the problems encountered by traditional solutions. The technical solution has obvious advantages, and the anti-interference, concurrency and load capacity are significantly improved.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0061] In order to solve the problem of wireless space communication channel utilization, traditional wireless communication networks solve this problem by allocating the time occupancy rate of the channel, that is, the network time allocation mechanism in which the host makes time division multiplexing for the slave, and allocates working time slices to the slave. The specific method is that after the slave first enters the network, the host calculates the slave's channel and channel occupancy rate, allocates the corresponding channel and time slice, and then generates a work configuration file and sends it to the slave, so that different slaves can work in different working time slices. The key lies in the effective use of channel time resources. At the same time, for the allocation of air interface channel resources, each slave will be fixed on the corresponding time slice of a channel.

[0062] However, this network allocation method is inefficient. On the one hand, each slave can only work in the corresponding polling time slice. If the transmission fails, it needs to wait for the next round of transmission time slice, which affects the timeliness of the alarm.

When there is environmental interference, this transmission may fail. The core disadvantage is that the timeliness of the network is insufficient, and the fire warning alarm wireless network requires the timeliness of the alarm as the core. At the same time, this method of allocating air interface resources has inherent defects in anti-interference, because the channels and time slices it allocates are fixed and regular, and it does not have sufficient anti-interference ability when encountering regular interference.
