In this embodiment, the cellular internet of things device may wake up at regular time to scan the system paging information of the network base station side, and if the system paging information of the network base station side can be scanned, it indicates that the system can scan the cellular network signal. After scanning the cellular network signal, the system initializes the count value of the built-in counting tool to an initial count value (for example, initializes the count value of the counting tool and then sets the count value to an initial count value 0). And the system controls the counting tool to start to count continuously according to a basic counting value corresponding to a preset time length, wherein the basic counting value is a value which is increased once when the counting tool counts. For example, the preset time duration is set to 5min, the basic count value is 1, and every 5 minutes, the current count value of the counting tool is increased by 1. The system monitors the current count value of the counting tool in real time (the current count value in this embodiment refers to the latest count value after real-time update), and automatically acquires a plurality of first receiving platforms corresponding to the current count value each time when the count value of the counting tool is monitored to be increased by one basic count value. Each count value corresponds to one or more receiving platforms, and the receiving platform in this embodiment includes an internet of things platform (for example, a cloud platform corresponding to each running APP) and a cellular network base station (the first receiving platform is included in the receiving platform and represents a part or all of platforms screened from all receiving platforms at the present time). Specifically, a receiving platform and count value mapping table is stored in an internal database (or a database in a cloud server) of the system, and one count value in the receiving platform and count value mapping table corresponds to one or more receiving platforms (which may be an internet of things platform or a cellular network base station). The system screens one or more first receiving platforms corresponding to the current count value from the receiving platform and the 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 correspondingly sends the respective data packets of the first receiving platforms to the screened first receiving platforms respectively, a uniform sending period is realized for sending the data packets between the cellular Internet of things equipment and the receiving platforms, the sending time of the data packets is managed in order, the waking times of the cellular Internet of things equipment are reduced, the cellular Internet of things equipment is prevented from being woken up repeatedly, the dormancy time of the cellular Internet of things equipment is effectively increased, and the power consumption of the equipment is reduced. In this embodiment, the data packet is used to maintain long IP data packet connection between the cellular internet of things device and the receiving platform and/or let the receiving platform know the status of the cellular internet of things device.
Further, the step of obtaining a plurality of first receiving platforms corresponding to the current count value includes:
s301, adding one basic count value on the basis of the initialized count value to obtain a first count value;
s302, a preset receiving platform and count value mapping relation table is called, a plurality of first receiving platforms corresponding to the first count values are screened from the receiving platform and count value mapping relation table, wherein one count value in the receiving platform and count value mapping relation table corresponds to one or more receiving platforms.
In this embodiment, when counting for the first time, after a preset duration elapses after the counting is started, a timing tool in the system adds a basic count value on the basis of the initialized count value to obtain a first count value, where the first count value is an updated count value (if a preset duration elapses again, a basic count value is added on the basis of the first count value, for example, the initial count value is 0, and when the first preset duration elapses, the current count value, i.e., the first count value in this embodiment is 1, and when the second preset duration elapses, the current count value is 2, and so on). Then, the system calls a pre-constructed receiving platform and count value mapping relation table, and the receiving platform and count value mapping relation table can be stored in a database in the system; or the system can be stored in a cloud server, and the system can acquire the data from the cloud server when needed. The receiving platform and count value mapping relation table comprises corresponding relations between count values and all receiving platforms, and one count value corresponds to one or more receiving platforms. The system screens one or more first receiving platforms corresponding to the first count value from the receiving platform and the count value mapping relation table according to the first count value.
Further, the step of monitoring whether a cellular network signal is scanned or not is preceded by the step of:
s5, detecting data packet sending frequencies agreed by protocols of the cellular Internet of things equipment and all receiving platforms respectively;
s6, obtaining the data packet sending interval duration corresponding to each receiving platform according to the data packet sending frequency;
and S7, calculating the least common multiple of the time length of the sending intervals of the data packets, and setting the value of the least common multiple as the value of the preset time length.
In this embodiment, before the receiving platform and the count value mapping table are not constructed (that is, before the system does not establish a uniform sending period of the data packet between the cellular internet of things device and each receiving platform), the system detects a data packet sending frequency agreed by a protocol between the cellular internet of things device and all receiving platforms (including the internet of things platform and the cellular network base station). After the data packet sending frequency between the cellular Internet of things equipment and each receiving platform is obtained, the data packet sending interval duration corresponding to each receiving platform is obtained through analysis according to the data packet sending frequency. Then, the system obtains the least common multiple between the sending interval durations of the data packets through the calculation of the mutual least common multiple, and sets the value of the calculated least common multiple as the value of the preset duration, wherein the least common multiple is the common sending interval duration of the data packets of each receiving platform. For example, if the packet transmission interval duration corresponding to the receiving platform a is 2min, the packet transmission interval duration corresponding to the receiving platform B is 6min, and the packet receiving duration corresponding to the receiving platform C is 10min, the calculated least common multiple is 30, and therefore the preset duration is 30 min.
In another embodiment, a time base register is disposed in the cellular internet of things device, the time base register is a timing tool constructed according to a data packet transmission time reference between the cellular internet of things device and each receiving platform, and if a cellular network signal is scanned, a count value is initialized, and a step of starting continuous counting with a preset duration corresponding to a basic count value includes:

and S202, starting to count continuously at fixed time through the time base register, wherein the count value of the time base register is the time-counting duration.
In this embodiment, a time base register is arranged in the system of the cellular internet of things device, the time base register is a timing tool constructed according to a data packet transmission time reference (i.e., a preset time duration in this embodiment) between the cellular internet of things device and each receiving platform, and each count unit of the time base register is 1 ms. Through software setting of the time base register, the time base register can wake up the cellular Internet of things equipment in a timing interrupt mode. After the system scans the cellular network signal, the current time is set as the time starting point of the time base register, and the count value of the time base register is initialized to the initial count value (i.e. set to 0). Then, a time register in the system starts to count continuously and time, and the sending time of the data packet starts to be monitored. The counting value of the time base register corresponds to the timing duration, and the unit is millisecond.
In another embodiment, the step of obtaining a plurality of first receiving platforms corresponding to the current count value when it is monitored that one of the base count values is added includes:
s303, monitoring whether the count value of the time-base register is integral multiple of the preset duration;
s304, if the counting value of the time base register is integral multiple of the preset duration, the time base register generates timing interruption and acquires a plurality of first receiving platforms corresponding to the current counting value.
In this embodiment, it can be known from the above that the count value of the time-based register is the timing duration, and the system monitors whether the count value of the time-based register is an integral multiple of the preset duration in real time. If the counting value of the time base register is integral multiple of the preset duration, the time base register can generate timing interruption, 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 real-time updated count value) according to the request of the time-base register. In this embodiment, the count value is represented by a number plus a preset time period, for example, if the preset time period is T, the initial count value is 0, and after adding one basic count value, the initial count value is 1T; and increasing a basic counting value again to be 2T, and so on.
Further, the step of waking up the cellular internet of things device to correspondingly send the respective data packets of the first receiving platforms to the first receiving platforms respectively includes:
s401: awakening the cellular Internet of things equipment according to the timing interruption generated by the time base register;
s402: and correspondingly sending the data packet of each first receiving platform to each first receiving platform through the cellular Internet of things equipment.
In this embodiment, the system awakens the cellular internet of things device through the timed interrupt generated by the time base register, and after the cellular internet of things device is awakened, the respective data packets of the first receiving platforms can be automatically and correspondingly sent to the first receiving platforms at the same time, so that the sending cycle of the data packets respectively corresponding to the receiving platforms is orderly managed, the cellular internet of things device does not need to be awakened repeatedly, the dormancy time of the cellular internet of things device is effectively prolonged, and the power consumption of the device is reduced.
Further, after the step of initializing the count value and starting to count continuously by a preset time duration corresponding to a basic count value if the cellular network signal is scanned, the method includes:
and S8, if the cellular network signal loss is monitored, setting the time base register to be invalid and stopping timing counting.
In this embodiment, after the system starts counting, if the cellular network signal is detected to be lost (i.e. no cellular network signal is scanned), the time base register is set to be invalid immediately, so that the time base register stops counting the timing. Subsequently, if the cellular network signal is re-scanned, the current time after the cellular network device re-registers to the cellular network needs to be set as the time starting point of the time base register, the count value of the time base register is initialized again and set to 0, and then the timer counting is continued under the condition that the network connection is maintained.

The system monitors the current count value of the counting tool in real time (the current count value in this embodiment refers to the latest count value after real-time update), and automatically acquires a plurality of first receiving platforms corresponding to the current count value each time when the count value of the counting tool is monitored to be increased by one basic count value. Each count value corresponds to one or more receiving platforms, and the receiving platform in this embodiment includes an internet of things platform (for example, a cloud platform corresponding to each running APP) and a cellular network base station (the first receiving platform is included in the receiving platform and represents a part or all of platforms screened from all receiving platforms at the present time).

If the counting value of the time base register is integral multiple of the preset duration, the time base register can generate timing interruption, 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 real-time updated count value) according to the request of the time-base register. In this embodiment, the count value is represented by a number plus a preset time period, for example, if the preset time period is T, the initial count value is 0, and after adding one basic count value, the initial count value is 1T; and increasing a basic counting value again to be 2T, and so on.

In this embodiment, the system awakens the cellular internet of things device through the timed interrupt generated by the time base register, and after the cellular internet of things device is awakened, the respective data packets of the first receiving platforms can be automatically and correspondingly sent to the first receiving platforms at the same time, so that the sending cycle of the data packets respectively corresponding to the receiving platforms is orderly managed, the cellular internet of things device does not need to be awakened repeatedly, the dormancy time of the cellular internet of things device is effectively prolonged, and the power consumption of the device is reduced.
Further, the packet sending apparatus further includes:
and the pause module 8 is used for setting the time base register to be invalid and stopping timing counting if the cellular network signal loss is monitored.
In this embodiment, after the system starts counting, if the cellular network signal is detected to be lost (i.e. no cellular network signal is scanned), the time base register is set to be invalid immediately, so that the time base register stops counting the timing. Subsequently, if the cellular network signal is re-scanned, the current time after the cellular network device re-registers to the cellular network needs to be set as the time starting point of the time base register, the count value of the time base register is initialized again and set to 0, and then the timer counting is continued under the condition that the network connection is maintained.
