And the system screens one or more first receiving platforms corresponding to the current count value from the receiving platform and count value mapping relation table according to the current count value of the counting tool. Finally, the system wakes up the cellular internet of things equipment, so that the cellular internet of things equipment respectively and correspondingly transmits the data packets of each first receiving platform to each first receiving platform obtained through screening, the data packet transmission between the cellular internet of things equipment and each receiving platform is realized to have a uniform transmission period, the orderly management of the transmission time of the data packets is facilitated, the wake-up times of the cellular internet of things equipment are reduced, the repeated wake-up of the cellular internet of things equipment is avoided, the sleep time of the cellular internet of things equipment is effectively increased, and the power consumption of the equipment is reduced.

After the system scans the cellular network signal, the current moment is set as the time starting point of the time base register, and the count value of the time base register is initialized, and the initialized count value is the initial count value (namely, set to 0). A time base register within the system then begins to continually count the timing and the time of transmission of the data packets begins to be monitored. The count value of the time base register corresponds to the timing duration, and the unit is millisecond.

If the count value of the time base register is an integer multiple of the preset duration, the time base register can generate a timing interrupt, so that the system is requested to process the sending action of the data packet preferentially. The system automatically acquires a plurality of first receiving platforms corresponding to the current count value (namely the count value updated in real time) according to the request of the time base register. In this embodiment, the count value is represented by a number plus a preset duration, for example, if the preset duration is T, the initial count value is 0, and after adding a basic count value, 1T is obtained; again, the increment of one base count value is 2T, and so on.

If the count value of the time base register is an integer multiple of the preset duration, the time base register can generate a timing interrupt, so that the system is requested to process the sending action of the data packet preferentially. The system automatically acquires a plurality of first receiving platforms corresponding to the current count value (namely the count value updated in real time) according to the request of the time base register. In this embodiment, the count value is represented by a number plus a preset duration, for example, if the preset duration is T, the initial count value is 0, and after adding a basic count value, 1T is obtained; again, the increment of one base count value is 2T, and so on.

In this embodiment, the system wakes up the cellular internet of things device through the timer interrupt generated by the time base register, and after the cellular internet of things device is woken up, the respective data packets of each first receiving platform are automatically and correspondingly sent to each first receiving platform at the same time, so that the sending period of the data packets corresponding to each receiving platform is orderly managed, repeated wake up of the cellular internet of things device is not needed, the sleep time of the cellular internet of things device is effectively prolonged, and the electric consumption of the device is reduced.
Further, the data packet transmitting device further includes:
a suspension module 8, configured to set the time base register to be invalid and stop timing counting if the cellular network signal loss is detected.
In this embodiment, after the system starts counting, if it detects that the cellular network signal is lost (i.e. the cellular network signal is not scanned), the time base register is set to be invalid immediately, so that the time base register stops timing counting. If the cellular network signal is scanned again later, the current time after the cellular network device is re-registered to the cellular network is required to be set as the time starting point of the time base register, the count value of the time base register is initialized again to be set as 0, and then the timing counting is continued under the condition that the network connection is maintained.
