when the device is in a first preset mode, when a sensor in the device is awakened to be in a working state, the device enters a stream pulling mode, a stream pulling request corresponding to a stream pulling platform connected with the device needs to be obtained, the stream pulling request indicates that video information collected by an image collecting module is obtained, the video information corresponding to the stream pulling request is determined from the image collecting module, the video information is processed according to a preset mode, the preset mode is that the video information is coded and packaged, the coded and packaged video information is sent to the stream pulling platform as stream pulling information until the stream pulling platform sends a stream pulling finishing instruction to the device, and the device exits the stream pulling mode.
The current battery electric quantity of equipment in the first preset mode exceeds the preset battery electric quantity, the equipment can regularly detect the battery electric quantity and the working state of a sensor, when no current pulling request exists and the current battery electric quantity exceeds the preset battery electric quantity, the equipment enters the second preset mode, in the second preset mode, an image acquisition module continues to acquire video information, and the sensor in the equipment has an image detection function, so that whether an abnormal condition exists in the video information is monitored based on the sensor, when the abnormal condition occurs, a honeycomb image module is wakened up, and abnormal information corresponding to the abnormal condition is reported to a current pulling platform.
Further, as the main processor and the cellular module in the second preset mode are powered normally, when the abnormal information needs to be reported to the pull leveling platform, second-level network recovery and data transmission can be realized.
In the second preset mode, in order to prevent the position of the device from being changed and cause the sensor in the device to detect an abnormal condition, so as to report the abnormal condition, the position change information corresponding to the device is determined based on the image detection function of the sensor, and the specific determination process is as follows:
the sensor acquires video data acquired in an image acquisition module, the lens multiple of the image acquisition module is not changed when the image acquisition module acquires the video data, the video data is analyzed into continuous multi-frame images, image difference values between adjacent images are calculated, whether the image difference values exceed a preset threshold value or not is judged, and when the image difference values exceed the preset threshold value, the position of equipment is determined not to be changed; when the image difference value is lower than a preset threshold value, determining that the position of the equipment is changed, and determining position change information corresponding to the equipment;
in a possible design, it is determined whether the device location is changed, and the device location may also be determined by obtaining historical location information in a location detection module, where the location detection module may be a Global Navigation Satellite System (GNSS), and when the historical location information in continuous time is inconsistent, it may be determined that the device location is changed, and location change information of the device is obtained; when the historical position information in the continuous time is consistent, the position of the representative equipment in the continuous time is not changed.
It should be noted that, when the position of the device is changed, determining a start time of the position movement of the device and an end time of the position movement stop of the device, calculating a time difference between the start time and the end time, and adding the time difference to a preset waiting time, where the preset waiting time is a time that is continuously waited after the end time, obtaining a change time duration corresponding to the position change information, after determining the change time duration, waiting for the change time duration to arrive, and after the change time duration arrives, the device reacquires a target cell currently connected and measurement data corresponding to the target cell, where the measurement data includes the target cell currently connected and a target cell selectable by the device.
When the current battery power of equipment is less than preset battery power and does not have and draws a class request, equipment will get into the third and predetermine the mode, and the third predetermines the mode and opens the back, and equipment can cut off the power supply with first default module set, and this first default module set includes in concentrated: the method comprises a main processor and a cellular communication module, and a second preset module is started, wherein the second preset module is an NBIOT module, the NBIOT module can complete network registration based on a connected SIM1 card, and receives communication data between equipment and a pull platform based on a registered account number corresponding to the SIM1 card, after the NBIOT module logs in the pull platform based on the registered account number, the keep-alive time length between the equipment and the pull platform is obtained, the keep-alive time length is the longest time interval when the equipment is not communicated with the pull platform, and if the equipment is not communicated with the pull platform within the keep-alive time length, the connection between the equipment and the pull platform is disconnected.
After the keep-alive time length of the equipment is determined, the keep-alive time length is used as the response time length of the equipment for responding to the pull platform, when the pull platform sends a pull request to the equipment, the equipment in a third preset mode responds in the response time length, the NBIOT module synchronizes the response time length to the pull platform and carries out periodic paging according to the response time length to determine whether the pull request exists in the paging period, and when the pull request of the pull platform is monitored, the power supply is carried out on the main processor and the cellular communication module through the low-power-consumption MCU module, the longer the response time length is, the longer the paging interval is, and therefore the power consumption of the equipment is lower.
Further, the NBIOT module in the device takes the response time length as a preset starting period corresponding to the sensor in the device, detects whether the sensor in the device is in a working state according to the preset period after the starting period of the sensor in the device is determined, controls the device to operate the first preset module again when the sensor is in the working state, and powers off the second preset module; when the sensor is not in a working state, the sensor is in a dormant state, when the dormant time of the sensor reaches a preset starting period, the control equipment sends heartbeat information to the pull leveling platform, the heartbeat information is used for informing the pull leveling platform that the equipment is in a normal state, and after the sensor sends the heartbeat information, the server controls the sensor to be in the dormant state.
Further, as shown in fig. 4, when the device is started, a cellular image module in the device is initialized to power on, an NBIOT module in the device is powered on and powered off, if the device has a GNSS module, the device initializes the GNSS module, initiates registration to a pull flow platform based on a cellular communication module, and the server needs to acquire a working mode of the device.
When the working mode of the equipment is not the first preset mode, the equipment starts an image motion detection function, judges whether a picture changes in video data acquired by an image acquisition module, and detects the working mode of the equipment again when the picture does not change; when the picture changes, if the position of the equipment is changed, the change duration is determined based on the steps described above, and when the change duration is reached, the neighbor cell measurement and the cell reselection are initiated once to obtain the measurement data.
When the working mode of the equipment is not the first preset mode and the second preset mode, the equipment enters a third preset mode, the first preset module set is powered off, the second preset module is started, the pull platform is registered based on the NBIOT module and is logged into the pull platform, the keep-alive duration and the response duration between the equipment and the pull platform are determined based on the description, after the response duration is determined, the paging cycle is determined based on the response duration, the equipment enters a power-saving mode when the NBIOT module is idle, whether the sensor is awakened or not needs to be judged after the power-saving mode is entered, and when the sensor is awakened, the equipment powers on the first preset module set and powers off the second preset module; when the sensor is not awakened, judging whether the sleeping time of the sensor reaches the keep-alive duration, when the keep-alive duration reaches, sending heartbeat information to the pull platform, and entering a power-saving mode after the heartbeat information is sent; when the keep-alive time is up, the sensor judges whether the sensor is awakened or not when the preset starting period is up.
