Description
Technical Field
The present application relates to the field of communications, and in particular, to a technique for transmitting data information.
Background
The narrowband internet of things (Narrow Band Internet of Things, NB-IoT) becomes an important branch of the internet of everything. The NB-IoT is built in the cellular network, consumes only about 180kHz bandwidth, and can be directly deployed in the GSM network, the UMTS network or the LTE network, so that the deployment cost is reduced, and smooth upgrading is realized. NB-IoT is an emerging technology in the IoT field that supports cellular data connectivity of low power devices over a wide area network, also known as a Low Power Wide Area Network (LPWAN). NB-IoT supports efficient connections for long standby times, high demand devices for network connections. NB-IoT device battery life is said to be improved by at least 10 years while still providing very comprehensive indoor cellular data connection coverage.
NB-IOT sensors typically employ COAP (Constrained Application Protocol) protocol and LWM2M (light M2M) protocol for data transmission. The network transport layer of COAP and LWM2M protocols employ UDP (User Datagram Protoco) protocols. UDP is a connectionless transport layer protocol that provides a transaction-oriented simple unreliable information transport service. The data transmission can be completed by one communication without handshake signals, and the server is not actively required to actively answer the data transmitted by the sensor. In fact, most of the communication mechanisms of NB-IOT sensors in the market at present do not need server response, so that the purpose of low power consumption is achieved. This also results in the communication of data from the sensor to the server not being known. And the current base station communication is influenced by various factors (such as base station equipment maintenance, weather factors and other interference factors). In addition, according to the characteristics of the NB network, the number of users accessing simultaneously at one time is about 12, and the more the number of NB devices in the same area is, the greater the risk of communication failure caused by data communication conflict is, and the accurate acquisition of data sent to a server by a wireless sensor at each time cannot be ensured. In order to improve the reliability of transmission, it is common practice to actively respond to the acknowledgement at the server application layer to improve the stability of communication. However, this method increases the acknowledgement time of the response wait of the sensor, resulting in an increase in power consumption and an increase in the number of transmission stripes.

In other words, the sensor performs loading and transmission of data information based on the data amount of the periodic data collected in the current reporting period and the current loading information, in other words, when there are spare data bits, the periodic data collected in the current reporting period is loaded based on the data amount of the periodic data collected in the current reporting period, so as to ensure the real-time performance of the data preferentially. Further, the network device does not acknowledge the target data packet sent by the sensor each time, and only when the target data packet meets the acknowledgement condition, the network device sends acknowledgement information to the sensor, so that the reliability of data transmission is improved, and meanwhile, the electricity consumption of the sensor due to the fact that the sensor receives the data information is reduced.

Fig. 1 shows a method for transmitting data information according to an embodiment of the present application, applied to a sensor, the method comprising steps S11, S12, S13. In step S11, the sensor responds to a reporting trigger event related to data information, and generates a target data packet according to the number of data and current loading information of a candidate data packet, wherein the candidate data packet includes data bits, the data bits are used for loading data information, the number of data includes the number information of periodic data acquired in the current reporting period, and the current loading information includes the number information of hollow remainder data bits in the candidate data packet; in step S12, the sensor sends the target data packet to the corresponding network device; in step S13, if the target data packet meets the response condition, the sensor receives response confirmation information about the target data packet sent by the network device; otherwise, the network device does not send acknowledgement information to the sensor. In some embodiments, the sensors include, but are not limited to, NB-IOT (Narrow Band Internet of Things, NB-IOT) sensors. In some embodiments, the sensor detects the acquired data information at regular intervals (e.g., 1 minute or 2 minutes, etc.). In some embodiments, the sensor sends a data packet to the corresponding network device once every certain reporting period (e.g., 30 minutes, etc.).
Specifically, in step S11, the sensor responds to a reporting trigger event related to data information, and generates a target data packet according to the number of data and current loading information of a candidate data packet, where the candidate data packet includes data bits, the data bits are used for loading data information, the number of data includes the number information of periodic data acquired in the current reporting period, and the current loading information includes the number information of remaining data bits in the candidate data packet. In some embodiments, the reporting trigger event includes, but is not limited to, reaching a reporting time (e.g., the sensor sends data to the corresponding network device every 30 minutes, although it will be understood by those skilled in the art that the 30 minutes described above are only examples, and may be 40 minutes or 20 minutes, etc.), the periodic data includes an alarm data identifier (e.g., when the sensor detects that the collected periodic data includes an alarm identifier, the sensor triggers generation of a target data packet, and timely sends the target data packet to the network device). In some embodiments, the reporting period includes, but is not limited to, a fixed period of 20 minutes, 40 minutes, etc. In other embodiments, when the periodic data includes an alarm tag, the reporting period includes a time interval between a time when the alarm tag was detected and a time when the data packet was last reported. In some embodiments, the periodic data includes data information collected during the present reporting period. In some embodiments, the data information includes, but is not limited to, periodic data, reissue data. Specifically, the data information may be measured values collected by the sensors, such as a pressure value, a battery power, a signal strength, an operation state, and the like. In some embodiments, the candidate data packets include historical data packets (e.g., the historical data packets include data packets that have been sent to the network device but for which acknowledgement information was not received). In other embodiments, the candidate data packet includes a new data packet (e.g., a first generated data packet, in other words, the new data packet is not generated based on the historical data packet). In some embodiments, the sensor is configured to generate a target data packet according to the number of data and the current loading information of the candidate data packet in response to the reporting trigger event. For example, if the number information of the periodic data collected in the current reporting period is less than or equal to the number information of the spare data bits, the periodic data collected in the current reporting period is used as target periodic data, and all the target periodic data are loaded into the candidate data packet to generate the target data packet. For the specific generation process of the target data packet, please refer to the following corresponding embodiments, which are not described herein. In some embodiments, it cannot be understood by those skilled in the art that the maximum data amount (typically 1024 bytes) of a single transmission by the NB sensor is determined by the radio frequency module (also called a wireless communication module). In some embodiments, the sensor responds to the report triggering event, generates a target data packet according to the data quantity and the current loading information of the candidate data packet, and sends the target data packet to the network device to complete the task of reporting the target data packet. In other words, each reporting trigger event corresponds to only one task of sending a target data packet to the network device.
In step S12, the sensor sends the target data packet to the corresponding network device. For example, after the sensor generates the target data packet, the sensor sends the target data packet to a corresponding network device to transmit data information.
In step S13, if the target data packet meets the response condition, the sensor receives response confirmation information about the target data packet sent by the network device; otherwise, the network device does not send acknowledgement information to the sensor. In some embodiments, the network device returns acknowledgement information to the sensor only if the target data packet satisfies the acknowledgement condition, and the network device does not return acknowledgement information to the sensor if the target data packet does not satisfy the acknowledgement condition. In some embodiments, for a target data packet that receives acknowledgement information, the sensor will delete a copy of the target data packet to free up local space; and for the target data packet which does not receive the response confirmation information, the sensor can store the copy of the target data packet as a historical data packet locally to be used as a candidate data packet of the next reporting period, continuously generate the target data packet, and generate the target data packet based on the historical data packet and send the target data packet to the network equipment again when the reporting trigger condition is met. In some embodiments, the response conditions include at least any one of:
(1) The amount of data information loaded in the target data packet reaches an amount threshold. In some embodiments, the number threshold includes, but is not limited to, 4, 5, 6, etc. Of course, those skilled in the art will recognize that the above-described number thresholds are merely examples, and that other number thresholds that may be present or later on are applicable to the present application, and are also within the scope of the present application and are incorporated herein by reference. For example, if the network device detects that the target data packet is full (e.g., the amount of data information in the target data packet reaches an amount threshold), the network device sends acknowledgement information to the sensor. In this embodiment, by setting the response condition such that one piece of data information is most likely to be transmitted the number threshold number of times (for example, the number threshold includes 5 and one piece of data information is most likely to be transmitted 5 times), the energy consumption caused by the reception of the information to the sensor is reduced while improving the communication reliability.
(2) The periodic data loaded in the target data packet comprises an alarm data identifier. In some embodiments, data information (e.g., alarm data) with high real-time requirements for data transmission, on the one hand, triggers the sensor to generate a target data packet so as to send the target data packet to the network device in real time; on the other hand, the network device is triggered to return response confirmation information to the sensor. For example, when the sensor detects that the collected periodic data comprises an alarm data identifier, the sensor triggers to generate a target data packet, and when the network equipment detects that the target data packet comprises the alarm data identifier, the network equipment sends response confirmation information to the sensor.
(3) The target data packet comprises identification information to be responded. For example, the sensor may also detect whether the target data packet satisfies that the amount of data information loaded in the target data packet reaches an amount threshold and/or that the periodic data loaded in the target data packet includes an alarm data identification. And if the sensor detects that the number of the data information in the target data packet reaches a number threshold value and/or the periodic data loaded in the target data packet comprises an alarm data identifier, the sensor adds identification information to be responded to into the target data packet, and the network equipment sends response confirmation information to the sensor when detecting that the target data packet comprises the identification information to be responded to. In some embodiments, when the network device detects that the amount of data information in the target data packet reaches an amount threshold, and/or the periodic data loaded in the target data packet includes an alarm data identifier, the sensor defaults to have the response waiting time after each time the target data packet is sent, and the sensor enters a sleep state after receiving the response confirmation information in the response waiting time. In other embodiments, when the sensor detects that the amount of data information in the target data packet reaches the amount threshold and/or the periodic data loaded in the target data packet includes an alarm data identifier, the sensor has a response waiting time (e.g., 20 seconds) only when the response condition includes that the target data packet includes identification information to be responded, and the sensor can still receive information (e.g., the response confirmation information) sent by the network device during the response waiting time, and enters a sleep state after receiving the response confirmation information during the response waiting time.
Of course, those skilled in the art will appreciate that the above-described response conditions are merely examples, and that other response conditions that may be present or later developed are applicable to the present application, and are also within the scope of the present application and are incorporated herein by reference.
In some embodiments, the data information is sequentially arranged and loaded in the data packets according to the acquisition time, and the generating the target data packet according to the data quantity and the current loading information of the candidate data packets includes: if the number of the data is smaller than or equal to the number of the spare data bits, taking the periodic data acquired in the current reporting period as target periodic data, and completely loading the target periodic data into the corresponding spare data bits in the candidate data packet to generate the target data packet; otherwise, determining target periodic data and reissue data from one or more periodic data acquired in the current reporting period, loading the target periodic data into corresponding spare data bits in the candidate data packet, and recording the reissue data in a database. In some embodiments, the data information is sequentially arranged and loaded on the corresponding data bits according to the acquisition time in the data packet, so that the sensor can determine the acquisition time of each data information in the data packet. For example, when the target historical data is determined from at least one historical data in the historical data packet, the target historical data is shifted out according to the arrangement sequence of the at least one historical data. For example, the at least one history data is sequentially arranged from one end to the other end (for example, from left to right, the acquisition time of the leftmost history data is earliest) of the data frame according to the acquisition time, and when the periodic data is redundant with spare data bits, the corresponding amount of history data is shifted and removed from the leftmost history data, so that the periodic data is loaded with the spare data bits. For example, if the number of periodic data collected in the current reporting period is less than or equal to the number of hollow data bits in the candidate data packet, the periodic data collected in the current reporting period may be all loaded into the corresponding spare data bits (for example, the corresponding spare data bits are sequentially loaded according to the collection time of each periodic data). If the number of the periodic data collected in the current reporting period is greater than the number of the spare data bits, determining target periodic data and reissue data from one or more periodic data collected in the current reporting period, loading the target periodic data into the corresponding spare data bits in the candidate data packet, and recording the reissue data in a database. In some embodiments, the sensor records the time of acquisition of each piece of data information acquired, e.g., the sensor records the time of acquisition of the reissue data when the reissue data is recorded in the database, so that the target reissue data is subsequently determined from the database based on the time of acquisition when the packaged reissue data is satisfied.
In some embodiments, if the number of data is smaller than the number of spare data bits, taking the periodic data collected in the current reporting period as target periodic data, and loading all the target periodic data into corresponding spare data bits in the candidate data packet, so as to generate the target data packet, including: if the data quantity is smaller than the number of the spare data bits, taking the periodic data acquired in the current reporting period as target periodic data, and completely loading the target periodic data into the corresponding spare data bits in the candidate data packet; if at least one piece of reissue data exists in the database, determining target reissue data from the at least one piece of reissue data according to the acquisition time of each piece of reissue data, wherein the acquisition time of the target reissue data is later than the acquisition time of the rest of reissue data; and loading the target concurrent data to corresponding vacant data positions in the candidate data packet to generate the target data packet. For example, the reissue data in the database includes data information that was not previously sent to the network device. For example, when the number of data of the periodic data is smaller than the number of the spare data bits, it is further required to query whether additional data exists in the lower database, and if the additional data exists, determining target additional data from the at least one additional data, so as to load the target additional data into the corresponding spare data bits, so that the generated target data packet can reach a full-load state. In some embodiments, the acquisition time of the reissue data is earlier than the acquisition time of the periodic data, so that when the target reissue data is loaded, the target reissue data is located on the side of the periodic data that is earlier in acquisition time. For example, if the acquisition time is sequentially close to the current time from left to right in the candidate data packet, the target reissue data is located at the left side of the periodic data. In some embodiments, the target reissue data may be randomly determined from the at least one reissue data. In other embodiments, the target concurrent data may also be determined from the at least one concurrent data according to a collection time, where the collection time of the target concurrent data is later than the collection time of the remaining concurrent data in the at least one concurrent data.
In some embodiments, the candidate data packet includes a historical data packet, where the transmission time of the historical data packet is earlier than the current reporting period, and the historical data packet includes at least one spare data bit and at least one historical data; and if not, determining target periodic data and reissue data from one or more periodic data acquired in the current reporting period, loading the target periodic data into corresponding vacant data bits in the target data packet, and recording the reissue data in a database, wherein the method comprises the following steps of: if the number of the data is greater than the number of the spare data bits and greater than the number of all the data bits of the historical data packet, moving the at least one historical data out of the historical data packet and recording the at least one historical data in a database as the complement data; determining target periodic data and reissue data from the one or more periodic data; loading all the target periodic data information into corresponding spare data bits in the historical data packet; recording the reissue data in a database; and if the number of the data is greater than the number of the vacant data bits and is smaller than the number of all the data bits of the candidate data packet, determining target historical data from the at least one historical data, moving the target historical data out of the historical data packet, and loading the target periodic data into the data bits corresponding to the target historical data, wherein the acquisition time of the target historical data is earlier than the acquisition time of the rest historical data in the at least one historical data. For example, the candidate data packet includes a history data packet. In some embodiments, the historical data packets include data packets that have been sent to the network device but for which acknowledgement information was not received. In some embodiments, the sensor temporarily stores a copy of the data packet, when the sensor sends the data packet to the network device but does not receive acknowledgement information of the data packet, the sensor continues to store the copy of the data packet, and uses the copy as a historical data packet, so that when the report triggering condition is met next time, a target data packet is generated based on the historical data packet, and the target data packet is sent to the network device. For example, the candidate data packet includes a history data packet. In some embodiments, the historical data packet includes at least one spare data bit and at least one historical data. When the number of the periodic data collected in the current reporting period is greater than the number of the spare data bits, there may be two cases, that is, the number of the periodic data is greater than the number of the spare data bits and greater than the number of all the data bits in the historical data packet, at this time, all the historical data in the historical data packet is moved out of the historical data packet, and the target periodic data and the complementary data are determined from the periodic data. In some embodiments, the sensor determines the target periodic data and the reissue data based on the time of acquisition of the one or more periodic data. For example, the most recently acquired periodic data is determined as the target periodic data. In yet another case, the number of data bits of the periodic data is greater than the number of spare data bits and less than the number of all data bits in the historical data packet, where the target historical data needs to be determined from at least one historical data in the historical data packet. And moving the target historical data out of the historical data packet so as to load the target periodic data to a corresponding position of the target historical data, wherein the acquisition time of the target historical data is earlier than the acquisition time of the rest historical data in the at least one historical data. In some embodiments, the data information is sequentially arranged in the data packet according to the acquisition time, so when the target historical data is shifted out, the historical data which is loaded to one end of the historical data packet at the earliest time can be selected, and the number of the historical data which needs to be shifted out is selected as the target historical data.
In some embodiments, the determining the target periodic data and the reissue data from the one or more periodic data includes: and determining target periodic data and reissue data from the one or more periodic data according to the acquisition time of each periodic data in the one or more periodic data, wherein the acquisition time of reissue data is earlier than the acquisition time of the target periodic data. In some embodiments, to ensure real-time performance of the data, the sensor packages the most recently acquired periodic data for transmission to the network device. For example, the sensor has recorded therein the acquisition time of each data information it acquires. When the target periodic data and the reissue data are required to be determined from the one or more periodic data, determining the target periodic data and the reissue data from the one or more periodic data according to the acquisition time of each periodic data in the one or more periodic data, wherein the acquisition time of the reissue data is earlier than the acquisition time of the target periodic data.
In some embodiments, the candidate data packet further includes a timestamp bit, where the timestamp bit is used to load a timestamp, and the timestamp includes a time base point and/or a target timing, and if the candidate data packet includes a historical data packet, the target time base point of the target data packet may be determined by the following calculation formula:
；
The process is as followsIncluding the target time base point, theA first historical time base point including a first historical data packet corresponding to the target data packet, theA target timing including the target data packet, theAnd the reporting period is included. In some embodiments, the target timing includes, but is not limited to, a time sequence number (e.g., 1, 2, 3, etc.), or a letter sequence number, etc., which is used to mark the transmission time of the target data packet. In some embodiments, the time base point includes specific time information (e.g., 2023, 3, 8). In some embodiments, the timestamp bits are loaded with a time basePoints and timing identifications. In other embodiments, the timestamp bits are loaded with only the target timing. When the timestamp bits are loaded with only the target timing, which is equivalent to compressing the timestamp, the target data packet can be loaded with more data information. In some embodiments, when the candidate data packet includes the historical data packet, the timestamp in the historical data packet includes only a target timing; when the candidate data packet includes the new data packet, a time stamp in the new data packet includes a time base point and a time sequence number. For example, to be able to load more data information, some embodiments enable a frame of data to encompass more, other valid information by way of a compressed time stamp. In some embodiments, the timestamp of the new data packet includes a time base point (e.g., 2023, 2, 1, 16: 00) and a timing (e.g., 0), if the sensor does not receive acknowledgement information sent by the network device after sending the new data packet to the network device (e.g., the new data packet does not reach full state, there are spare data bits). The sensor stores a copy of the new data packet as a first historical data packet locally. For example, the first historical time base point of the first historical data packet includes 2023, 2, 1. When the report trigger condition is satisfied again, the sensor generates a target data packet according to the number of data and the current loading information of the candidate data packet (for example, the history data packet), and then the timestamp of the target data packet only includes a target time sequence (for example, 1), and the length of the timestamp is compressed through the target time sequence, so that one frame of data can provide data bits as much as possible to load more data information. For example, the first historical time base point includes 2023, 2, 1, 16:00, the target time sequence includes 1, the reporting period includes 30 minutes, and then the target time base point includes 2023, 2, 1, 16:30.

In some embodiments, the one-to-one module is configured to take the periodic data collected in the current reporting period as target periodic data if the number of data is less than or equal to the number of spare data bits, and load the target periodic data all into corresponding spare data bits in the candidate data packet, so as to generate the target data packet; otherwise, determining target periodic data and reissue data from one or more periodic data acquired in the current reporting period, loading the target periodic data into corresponding spare data bits in the candidate data packet, and recording the reissue data in a database.
Here, the specific implementation manner of the one-to-one module correspondence is the same as or similar to the specific embodiment of the step S12, so that a detailed description is omitted and incorporated herein by reference.
In some embodiments, the one-to-one module is configured to take the periodic data collected in the current reporting period as target periodic data if the number of data is smaller than the number of spare data bits, and load the target periodic data all into corresponding spare data bits in the candidate data packet; if at least one piece of reissue data exists in the database, determining target reissue data from the at least one piece of reissue data according to the acquisition time of each piece of reissue data, wherein the acquisition time of the target reissue data is later than the acquisition time of the rest of reissue data; and loading the target concurrent data to corresponding vacant data positions in the candidate data packet to generate the target data packet.
Here, the specific implementation manner of the one-to-one module correspondence is the same as or similar to the specific embodiment of the step S12, so that a detailed description is omitted and incorporated herein by reference.
In some embodiments, the one-to-one module is configured to move the at least one historical data out of the historical data packet and record the at least one historical data in the database as the reissue data if the number of data is greater than the number of spare data bits and greater than the number of all data bits of the historical data packet; determining target periodic data and reissue data from the one or more periodic data; loading all the target periodic data information into corresponding spare data bits in the historical data packet; recording the reissue data in a database; and if the number of the data is greater than the number of the vacant data bits and is smaller than the number of all the data bits of the candidate data packet, determining target historical data from the at least one historical data, moving the target historical data out of the historical data packet, and loading the target periodic data into the data bits corresponding to the target historical data, wherein the acquisition time of the target historical data is earlier than the acquisition time of the rest historical data in the at least one historical data.
Here, the specific implementation manner of the one-to-one module correspondence is the same as or similar to the specific embodiment of the step S12, so that a detailed description is omitted and incorporated herein by reference.
In some embodiments, the one-to-one module is configured to determine, from the one or more periodic data, target periodic data and reissue data according to an acquisition time of each of the one or more periodic data, where the acquisition time of reissue data is earlier than the acquisition time of the target periodic data.
In some embodiments, the candidate data packet further includes a timestamp bit, where the timestamp bit is used to load a timestamp, and the timestamp includes a time base point and/or a target timing, and if the candidate data packet includes a historical data packet, the target time base point of the target data packet may be determined by the following calculation formula:；
the process is as followsIncluding the target time base point, theA first historical time base point including a first historical data packet corresponding to the target data packet, theA target timing including the target data packet, theAnd the reporting period is included. In some embodiments, the target timing includes, but is not limited to, a time sequence number (e.g., 1, 2, 3, etc.), or a letter sequence number, etc., which is used to mark the transmission time of the target data packet. In some embodiments, the time base point includes specific time information (e.g., 2023, 3, 8). In some embodiments, the timestamp bits are loaded with a time base point and a timing identification. In other embodiments, the timestamp bits are loaded with only the target timing. When the time is When the stamp bit is loaded with only the target timing, which corresponds to compressing the time stamp, the target data packet can be loaded with more data information. In some embodiments, when the candidate data packet includes the historical data packet, the timestamp in the historical data packet includes only a target timing; when the candidate data packet includes the new data packet, a time stamp in the new data packet includes a time base point and a time sequence number. For example, to be able to load more data information, some embodiments enable a frame of data to encompass more, other valid information by way of a compressed time stamp. In some embodiments, the timestamp of the new data packet includes a time base point (e.g., 2023, 2, 1, 16: 00) and a timing (e.g., 0), if the sensor does not receive acknowledgement information sent by the network device after sending the new data packet to the network device (e.g., the new data packet does not reach full state, there are spare data bits). The sensor stores a copy of the new data packet as a first historical data packet locally. For example, the first historical time base point of the first historical data packet includes 2023, 2, 1. When the report trigger condition is satisfied again, the sensor generates a target data packet according to the number of data and the current loading information of the candidate data packet (for example, the history data packet), and then the timestamp of the target data packet only includes a target time sequence (for example, 1), and the length of the timestamp is compressed through the target time sequence, so that one frame of data can provide data bits as much as possible to load more data information. For example, the first historical time base point includes 2023, 2, 1, 16:00, the target time sequence includes 1, the reporting period includes 30 minutes, and then the target time base point includes 2023, 2, 1, 16:30. In some embodiments, the timing sequence of the first historical data packet is zero, the timing sequence of the second historical data packet generated by taking the first historical data packet as the candidate data packet is 1, the timing sequence of the third historical data packet generated by taking the second historical data packet as the candidate data packet is 2, and so on, thereby recording the target timing sequence of the target data packet generated in the current reporting period.
In some embodiments, the response conditions include at least any one of:
(1) The amount of data information loaded in the target data packet reaches an amount threshold. In some embodiments, the number threshold includes, but is not limited to, 4, 5, 6, etc. Of course, those skilled in the art will recognize that the above-described number thresholds are merely examples, and that other number thresholds that may be present or later on are applicable to the present application, and are also within the scope of the present application and are incorporated herein by reference. For example, if the target data packet is full (e.g., the amount of data information in the target data packet reaches an amount threshold), the network device sends acknowledgement information to the sensor. In this embodiment, by setting the response condition such that one piece of data information is most likely to be transmitted the number threshold number of times (for example, the number threshold includes 5 and one piece of data information is most likely to be transmitted 5 times), the energy consumption caused by the reception of the information to the sensor is reduced while improving the communication reliability.
(2) The periodic data loaded in the target data packet comprises an alarm data identifier. In some embodiments, data information (e.g., alarm data) with high real-time requirements for data transmission, on the one hand, triggers the sensor to generate a target data packet so as to send the target data packet to the network device in real time; on the other hand, the network device is triggered to return response confirmation information to the sensor. For example, when the sensor detects that the collected periodic data comprises an alarm data identifier, the sensor triggers to generate a target data packet, and when the network equipment detects that the target data packet comprises the alarm data identifier, the network equipment sends response confirmation information to the sensor.
(3) The target data packet comprises identification information to be responded. For example, the sensor may also detect whether the target data packet satisfies that the amount of data information loaded in the target data packet reaches an amount threshold and/or that the periodic data loaded in the target data packet includes an alarm data identification. And if the sensor detects that the number of the data information in the target data packet reaches a number threshold value and/or the periodic data loaded in the target data packet comprises an alarm data identifier, the sensor adds identification information to be responded to into the target data packet, and the network equipment sends response confirmation information to the sensor when detecting that the target data packet comprises the identification information to be responded to. In some embodiments, when the network device detects that the amount of data information in the target data packet reaches an amount threshold, and/or the periodic data loaded in the target data packet includes an alarm data identifier, the sensor defaults to have the response waiting time after each time the target data packet is sent, and the sensor enters a sleep state after receiving the response confirmation information in the response waiting time. In other embodiments, when the sensor detects that the amount of data information in the target data packet reaches the amount threshold and/or the periodic data loaded in the target data packet includes an alarm data identifier, the sensor has a response waiting time (e.g., 20 seconds) only when the response condition includes that the target data packet includes identification information to be responded, and the sensor can still receive information (e.g., the response confirmation information) sent by the network device during the response waiting time, and enters a sleep state after receiving the response confirmation information during the response waiting time.
