As shown in fig. 1 to 4, a method for switching a network by a wearable device includes the following steps:
as shown in fig. 1, when the central control system is initialized, a network is accessed by adopting a GSM network access manner, so as to realize normal communication between the wearable device and the internet; and in the running process of the central control system, switching to a WIFI network access mode or a Bluetooth network access mode in a response interruption mode.
As shown in fig. 2, the execution process of the interrupt response mode is as follows:
step one, a WIFI network access module or a Bluetooth network access module initiates a network access interruption request, corresponding to an interruption position 1;
step two, the central control system runs the RTOS, responds to the interrupt, closes the corresponding interrupt request function, and puts the corresponding interrupt into position 0;
thirdly, accessing the network by adopting WIFI or Bluetooth and continuously sending information;
and step four, when the WIFI or the Bluetooth is simultaneously transmitted in the network, the WIFI interruption request is preferentially responded and the Bluetooth interruption request is cancelled because the WIFI interruption request is higher than the Bluetooth interruption request.
As shown in fig. 3, the process of determining the connection/disconnection of the WIFI network access is as follows:
step one, a central control system continuously sends three heartbeat packets to an equipment connecting end at regular time;
step two, the central control system receives heartbeat packets in a DMA mode, if at least one heartbeat packet is received, the WIFI connection is confirmed to be normal, otherwise, the WIFI connection is disconnected;
and step three, when the WIFI disconnection is confirmed, allowing the WIFI request to be interrupted, and switching to a GSM network connection mode.
Specifically, the WIFI network access module triggers a WIFI interruption response bit of the central control system, requests a network access interruption response at the interruption response position 1, interrupts the central control system response, stops the GSM network, switches to a WIFI network access connection mode to connect the network, closes the WIFI interruption response, and responds to the interruption response position 0. If the two interrupts are generated simultaneously, the WIFI network access connection mode is preferentially adopted. If the two connection modes are disconnected, a GSM network is adopted; whether the WIFI access network connection mode is disconnected or not is judged by judging whether the heartbeat packet is received or not, if the heartbeat packet is received, the WIFI access network connection mode is connected, and if the heartbeat packet is not received, the WIFI access network connection mode is disconnected (a GSM network is adopted for disconnection).
As shown in fig. 4, the process of determining the connection/disconnection of the bluetooth network access connection is as follows:
step one, a central control system reads the high level frequency of an LED pin of a Bluetooth module in a DMA mode, and if the high level frequency is 0.5HZ, the Bluetooth is considered to be disconnected; if the high level frequency is 0.2HZ, the Bluetooth connection is considered to be normal;
and step two, when the disconnection of the Bluetooth is confirmed, the Bluetooth request is allowed to be interrupted, and the connection mode is switched to a GSM network connection mode.
Specifically, the Bluetooth networking module triggers a Bluetooth interrupt response bit of a central control system, requests a networking interrupt response at an interrupt response position 1, responds to the interrupt by the central control system, stops the GSM network, switches to a Bluetooth networking connection mode to connect a local area network, closes the Bluetooth interrupt response, and simultaneously responds to an interrupt response position 0; whether the Bluetooth is disconnected or not in the network access connection mode is judged by judging the PWM waveform change of the LED pin of the Bluetooth module, if the high level frequency in one period is 0.2HZ, the connection is carried out, and if the high level frequency is 0.5HZ, the disconnection is carried out (a GSM network is adopted for disconnection).
A system for switching a network of wearable equipment comprises a central control system, and a Bluetooth networking module, a WIFI networking module and a GSM networking module which are connected with the central control system; the Bluetooth networking module adopts an HC-05 module, the WIFI networking module adopts an SKW92A module, and the GSM networking module adopts an SIM900 module.
