Embodiment 1

[0038] see figure 1 , the present invention provides a kind of synchronous control method in wireless network, described synchronous control method comprises the following steps:

[0039] S1), the sending end sends broadcast packets carrying control instructions to multiple receiving ends through the wireless network, and the broadcast packets corresponding to the same control instruction are repeatedly sent N times at the same time interval, and each broadcast packet contains the broadcast packet according to the repeated sending The serial number of time sequence calibration;

[0040] Each broadcast packet in the N broadcast packets contains the sequence number of the broadcast packet sent in time order, for example, the sequence number of the broadcast packet in the first broadcast packet is 1, and the sequence number of the broadcast packet in the second broadcast packet is 2 , and so on, the sequence number of the broadcast packet in the i-th broadcast packet is i.

Embodiment 2

[0055] The present invention also provides a smart home system, which includes a control terminal and a plurality of receiving device ends wirelessly controlled by the control terminal, such as figure 2 As shown, the control terminal includes:

[0056] The broadcast packet modifying module 1 is configured to insert the serial number of the broadcast packet into the broadcast packet.

[0057] The first radio frequency communication module 2, the first radio frequency communication module 2 is connected to the broadcast packet modification module 1, and is used to send the broadcast packet modified by the broadcast packet modification module 1;

[0058] As an example, the control terminal also includes an encryption module (not shown) for encrypting broadcast packets to improve the security of data transmission, the input of the encryption module is connected to the output of the broadcast packet modification module 1, The output end of the encryption module is connected to th...

Abstract

The invention provides a synchronous control method in a wireless network and an intelligent home system. Serial numbers of corresponding broadcast packets are inserted into broadcast packets, which are repeatedly sent. Control terminals do not need complicated calculation, the circuit structure of control terminals is simple, and the design cost is saved. For the receiving equipment terminals, through a calculation module and an execution time appointing module, simple time linear prediction is carried out to realize synchronous execution of all receiving equipment, and the channel congestionand interference are avoided. Under the situation of unidirectional control and absence of handshaking signal, at a uniform execution time, all controlled facilities can simultaneously perform the control command. The provided synchronous control method has a wide application range, and is suitable for star type networking and Mesh type networking.

Description

technical field [0001] The invention relates to the field of smart home, in particular to a synchronization control method in a wireless network and a smart home system. Background technique [0002] With the rapid development of mobile intelligent terminals represented by mobile phones, wireless applications represented by remote controls or mobile phones have become the main experience in people's lives. One-to-one control has become the most mainstream wireless remote control method. At the same time, the one-to-many control method has increasingly become an indispensable remote control method. For example: control the lights in the house at the same time. Since the broadcast remote control does not require complex handshake interaction, one-to-many operation can be easily realized, the encryption mechanism is simple, and the mobile phone / remote control can be controlled at the same time, which is cost-effective, so it can be widely used in smart home systems.
