Main element symbol description is as follows:
10, main control system 11, concatenation unit
12, the first wireless communication module 13, the second wireless communication module
Embodiment
In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.
Refer to Fig. 1, combination wireless connection system of the present utility model, comprise main control system 10 and polylith concatenation unit 11, on main control system 10, be provided with the first wireless communication module 12, on every concatenation unit 11, being provided with the second wireless communication module 13, the first wireless communication modules 12 is connected with the second wireless communication module 13 wireless telecommunications respectively.
Situation compared to prior art, the combination wireless connection system that the utility model provides, on main control system 10, be provided with the first wireless communication module 12, on every concatenation unit 11, be provided with the second wireless communication module 13, utilize two wireless communication modules to carry out wireless telecommunications, can, so that combination connects up conveniently in assembling process, in use safeguard simple, meanwhile, all concatenation units 11 can both indistinguishably receive all control commands that main control system 10 sends.
In the present embodiment, in above-mentioned main control system 10, be provided with random number receiver module (not shown), in every concatenation unit 11, be provided with random number sending module (not shown), random number receiver module is electrically connected to the first wireless communication module 12, and random number sending module is electrically connected to the second wireless communication module 13.Random number sending module in every concatenation unit 11 produces after random number, utilize the second wireless communication module 13 wireless transmission separately, the first wireless communication module 12 of main control system 10 receives after random number, automatically identify the positional information of each concatenation unit 11, and produce address code according to the positional information of each concatenation unit.
In the present embodiment, in above-mentioned main control system 10, be provided with address code sending module (not shown), in every concatenation unit 11, be provided with address code receiver module (not shown), address code sending module is electrically connected to the first wireless communication module 12, and address code receiver module is electrically connected to the second wireless communication module 13.The address code sending module of main control system 10 produces address code, utilize the first wireless communication module 12 wireless transmission, the second wireless communication module 13 on every concatenation unit 11 receives after address code, one's own address code is delivered in address code receiver module, carried out the address code setting of concatenation unit separately.
