VI. Description of the Invention: [Technical Field of the Invention] The present invention relates to a wireless transmission system and method. [Prior Art] With the rapid development of information technology and the rising demand of users, many manufacturers have invested in the research and development of wireless technology, with the aim of enabling users to get rid of the constraints of various lines in daily life. In recent years, low-rate wireless network devices have attracted attention in the fields of home appliances, toys, industry, security, and medical care. Due to its low cost, low power consumption, and easy deployment, it is especially suitable for applications with low maintenance and wide service area. _ Among the various low-rate wireless network protocols, the most representative standard is IEEE 802.15.4 (ZigBee). In the ZigBee wireless network, limited by the radio wave intensity, it can cover a limited range. To establish a large-area service area, it is usually necessary to use a network relay node to integrate the radio wave φ coverage into a large-area network. Road service range. Referring to Figure 1 '1', the architecture of the prior art ZigBee wireless network system is illustrated. As shown, the conventional ZigBee wireless network system 7 includes a coordinator (7), a transmitting node (n), a receiving node 73, and a first bridge (access p). 〇int) 72, a second bridge 74, a third bridge 76, and a fourth bridge 78. The coordinator 70 is responsible for the establishment of the ZigBee wireless network system 7, which includes a routing lookup table and a service binding query table. The service binding query table 201146072 records each node 71 '73 and the bridge 72, %, and road address. The route check is to record the route J78 of the data packet. In addition, the nodes 71, 73 and the bridges 72, 74 are connected to the coordination II 7G. When the transmitting node 71 wants to transmit the connection point 73, since the radio wave of the transmitting node 71 does not have 73', it needs to be transmitted in the forwarding manner, using the front=points 74, 76, 78 to the receiving section, point 73, and its packet is roughly = The transmission path 7a shown by the broken line in the figure can be transmitted. Path 7a is arranged by coordinator 70. However, in the ZigBee wireless network, each node often enters a power-saving sleep state for the purpose of power saving, such as turning off the cover line antenna. At this time, as the transmission path la shows, the receiving node 73 causes the problem that the packet is missed due to the correct receipt of the packet. In addition, in the ZigBee I line network, when the Lai II 70 crashes or is disconnected, it cannot arrange the transmission path, causing the entire ZigBee wireless network system 7 to fail.

Further, when the third-order transmitter 12f executes the listening program, the third-order transmitter 12f receives the data signal from the terminal node 14a (steps are used and when the second-order transmitter 12e performs the listening program, the second order The second node Hb receives the data signal (step S86a). The I terminal progresses, and when the second-order transmitter 12f executes the forwarding procedure, the third-order transmitter 12f transmits the data signal (step S84b). The step 12e sends == (= S86b) 〇, step, when the second-order transmitter 12c executes the cross-listening program, the second-order transmitter 12c receives the data signal from the second-order transmitter 12f (step S84c) And when the first-order transmitter 12b executes the Wei program, the first-order transmitter (10) receives the data signal from the second-order relay H 12e (step test).

Note that in practice, the wireless transmission system of the present invention includes the number of Shierjie hierarchy to be adjusted, and is not limited to the actual description of the present specification, the wireless transmission system according to the present invention The monitor, the transmitter, and the terminal node can perform signal transmission and reception according to the program second return program, the Wei program, and the forwarding program by using the timing signal. Thereby, the wireless transmission system of the present invention can perform multiple levels. Wireless transmission ° in addition' The wireless mess of the present invention does not require coordination 1 to perform the transmission control arrangement' to reduce the risk of system failure as previously described. With the above detailed description of the preferred embodiments, it is desirable to more clearly describe the present invention. The features and spirits of the present invention are not limited by the specific embodiments disclosed above. Conversely, it is intended to cover various changes and equivalence arrangements as claimed in the present invention. The scope of the patent scope of the invention is therefore intended to be broadly interpreted in light of the above description so that it covers all possible modifications and equivalent arrangements.
