Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0062] In order to realize adaptive matching of working modes between devices that need to establish a connection, an embodiment of the present invention provides a mode adaptive matching method in a monitoring system. The method can be applied to the process of establishing a connection between two devices supporting multiple working modes, so as to realize the self-adaptive matching of the working modes of the two devices, and then establ...

Abstract

The invention discloses a mode adaptive matching method, apparatus and system in a monitoring system. In the method, a first device is configured to switch N operation modes supported by the first device according to a set period, a second device is configured to switch M operation modes supported by the second device according to a set time interval, wherein the time interval for switching the operation modes of the second device is greater than or equal to the set period of the first device; the first device initiates connection establishment to the second device after switching to a certain operation mode, and if the first device and the second device are successfully established, the first device and the second device hole the current operation modes and stops switching the operation modes so as to realize an adaptive matching of the operation modes between the devices requiring the establishment of connection without human operation. It can be ensured that the mode matching of the first device and the second device can be completed within one cycle period of the second device, thereby avoiding the uncertainty of random switching.

Description

technical field [0001] The invention relates to the field of monitoring systems, in particular to a pattern adaptive matching method, equipment and system in the monitoring system. Background technique [0002] In the prior art, various interface chips may be disposed inside the electronic device, therefore, the electronic device may support multiple interface modes. When establishing a connection between different devices, pattern matching is required. [0003] For adaptive matching of different rates on the same medium, for example, ordinary network physical layer (PHY) chips support 10\100\1000Base-T, the specific method is: use different data transmission auto-negotiation signals for pre-negotiation , this kind of negotiation signal adopts pulse mode, which is different from data transmission. Only when the negotiation pulse notifies each other of the modes supported by each other can it decide which interface mode to use for data transmission for adaptive matching. ...
