Specific embodiment
Present invention will now be described in further detail with reference to the embodiments and the accompanying drawings, but embodiments of the present invention are unlimited
In this.
As shown in figures 1-4, a kind of method of wearable device handover network, includes the following steps:
As shown in Figure 1, central control system initialize when using GSM network access mode access network, realize wearable device with
The normal communication of internet；In central control system operational process, WIFI network access mode is switched to by way of interrupt response
Or bluetooth network access mode.
Wherein, as shown in Fig. 2, the implementation procedure of the interrupt response mode are as follows:
Step 1, WIFI networking module or bluetooth networking module initiate networking interrupt requests, corresponding interruption position 1；
Step 2, central control system run RTOS, and response is interrupted, and corresponding interrupt requests function is closed, will be corresponding
Interruption position 0；
Step 3 is networked using WIFI or bluetooth, continues to send information；
Step 4 when WIFI or bluetooth networking while being sent, excellent since WIFI interrupt requests are higher than bluetooth interrupt requests
WIFI interrupt requests are first responded, and cancel bluetooth interrupt requests simultaneously.
Wherein, as shown in figure 3, the WIFI, which networks, connects the judgement process of on-off are as follows:
Step 1, central control system timing continuously transmit three heartbeat packets to equipment connecting pin；
Step 2, central control system use dma mode, receive heartbeat packet, true if receiving at least one heartbeat packet
It is normal to recognize WIFI connection, otherwise WIFI is disconnected；
Step 3 then allows WIFI request to interrupt, and is switched to GSM network connection side when confirmation WIFI is disconnected
Formula.
Specifically, WIFI networking module triggers central control system WIFI interrupt response position, by the interrupt response position
1 is set, networking interrupt response is requested, central control system response is interrupted, stops GSM network, be switched to WIFI networking connection type
Network is connected, and closes WIFI interrupt response, while by the interrupt response position 0.Above if two kinds interrupt while generating,
Then preferentially use WIFI networking connection type.GSM network is used if two kinds of connection types disconnect；It networks and connects for WIFI
It is connection if receiving heartbeat packet, if not receiving the heart by judging whether to receive heartbeat packet whether connecing its disconnection of mode
Bao Zewei is jumped to disconnect and (disconnect and then use GSM network).
Wherein, as shown in figure 4, the bluetooth, which networks, connects the judgement process of on-off are as follows:
Step 1, central control system use dma mode, read bluetooth module LED pin high level frequency, if high electricity
Flat frequency is 0.5HZ, then it is assumed that bluetooth disconnects；If high level frequency is 0.2HZ, then it is assumed that bluetooth connection is normal；
Step 2, when confirmation bluetooth disconnect, then allow BlueTooth request to interrupt, and be switched to GSM network connection side
Formula.
Specifically, the bluetooth interrupt response position of bluetooth networking module triggering central control system, by the interrupt response
Position 1, requests networking interrupt response, and central control system response is interrupted, stops GSM network, be switched to bluetooth networking connection side
Formula connects local area network, and closes bluetooth interrupt response, while by the interrupt response position 0；It networks and connects for bluetooth
By judging that bluetooth module LED pin PWM waveform changes whether its disconnection of mode, if high level frequency is in a cycle
0.2HZ is then connection, is then to disconnect and (disconnecting then using GSM network) if 0.5HZ.
A kind of system of wearable device handover network, including central control system, and with the central control system phase
Bluetooth networking module, WIFI networking module and the GSM networking module of connection；The bluetooth networking module uses HC-05 module, institute
WIFI networking module is stated using SKW92A module, the GSM networking module uses SIM900 module.
