Description
Technical field
The utility model relates to a kind of low consumption control mode of wireless network interior joint, especially this is related to based on a kind of communication system on any wireless communication networks, can make while in network, single node power consumption reduces greatly, to implement the relatively real-time control of this node.
Background technology
When there is hundreds and thousands of nodes in a wireless network simultaneously, each node power consumption reduces little by little, and the power consumption of whole network will reduce a lot.In order to reduce the power consumption of individual node, the node most of the time is usually needed all to be in deep sleep state.Under this resting state, node can not carry out data transmit-receive.And for the application that some control in real time, the switch of such as light fixture, needs communication delay enough little, to such an extent as to significantly can not be felt out by people the delay of action.For the node being in deep sleep state, at this moment communication is can not be successful.This can cause operation to lose or action postpones.
The utility model, in order to overcome above-mentioned defect, has carried out useful improvement.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides the real-time communication control system to low power consumption node in a kind of wireless network.
To achieve these goals, the utility model is by the following technical solutions:
To the real-time communication control system of low power consumption node in a kind of wireless network, comprise master controller and node, its special character is: described master controller controls node, wherein said master controller is the master controller with MCU microprocessor, described node is the LED bulb with control chip, described master controller comprises radio frequency chip, single-chip microcomputer and LCM dot matrix lcd module and keyboard, described LED bulb is provided with radio frequency chip and single-chip microcomputer, radio frequency chip on wherein said main controller and the radio frequency chip in LED bulb carry out two-way wireless communication, and the light on and off of LED bulb are controlled, radio frequency chip on wherein said main controller and the radio frequency chip in LED bulb all adopt 2.4 frequency range nRF401 radio frequency chips of Nordic company, frequency synthesizer is provided with in described radio frequency chip, power amplifier, crystal oscillator and modulator, its built-in address compares and CRC check function, radio frequency chip on described main controller and the single-chip microcomputer in LED bulb are by the two-way communication of RS485 bus, described keyboard is connected on single-chip microcomputer, single-chip microcomputer on described master controller also passes through the two-way communication of RS485 bus with LCM dot matrix lcd module,
Further, described radio communication is bluetooth or WIFI communication, and the compiled information of master control adopts ShockBurst mode to send to LED bulb;
Further, the built-in house dog of the single-chip microcomputer on described master controller and reset circuit, and be provided with 2 asynchronous serial ports.
The beneficial effects of the utility model: each the node average power consumption in network reduces greatly, thus the overall power significantly improving whole network; Master controller or operator can carry out relatively real-time control to each node.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the control principle drawing of the utility model embodiment.
Fig. 3 is the control principle drawing of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Embodiment of the present utility model is with reference to shown in Fig. 1-2, to the real-time communication control system of low power consumption node in a kind of wireless network, comprise master controller 1 and node 2, described master controller 1 pair of node 2 controls, wherein said master controller 1 is the master controller with MCU microprocessor, described node 2 is the LED bulb with control chip, described master controller 1 sends a synchronization packets every a bit of time span T1 to each node 2, a destination address is comprised in synchronization packets, be used to refer to the destination address of next packet, after described node 2 receives synchronization packets, if the destination address of the follow-up data bag indicated by this packet is not oneself, then penetration depth resting state, time span is T2, described time span T2 is less than but closely T1, this node 2 can be waken up before master controller 1 sends next synchronization packets, if the destination address of the follow-up data bag indicated by this packet is oneself, then wait-receiving mode control data bag, node 2 receives control data and after performing control command, penetration depth resting state, time span is T3, the length of 7.T3 is for ensureing that this node can be waken up before next synchronization packets.
The above execution mode only have expressed a kind of execution mode of the present utility model, but therefore can not be interpreted as the restriction to the utility model scope.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
