Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations. Accordingly, the following detailed description of the embodiments of the application provided in the appended drawings is not intended to limit the scope of the claimed application, but rather to represent selected embodiments of the application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without any creative work shall fall within the scope of protection of this application.

It should be noted that similar reference numerals and letters represent similar items in the following figures, therefore, once an item is defined in one figure, it does not need further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", etc. are only used to differentiate the description and cannot be understood as indicating or implying relative importance.

In the first aspect, this application provides a method for reducing the power consumption of NB-IOT equipment. The method is applied to the equipment terminal 10. The method includes the steps:

A1. Compare the data to be sent with the reference data in the first pre-stored database;

A2. Based on the comparison results, convert the data to be sent into data to be sent consisting of reference data numbers and/or data packets;

A3. Send the data to be sent to the NB-IOT device 20, so that the NB-IOT device 20 forwards the data to be sent to the base station 30.

Specifically, since the power consumption of the NB-IOT device 20 is mainly affected by the size of the data that needs to be forwarded, the larger the data to be forwarded, the power consumption of the NB-IOT device 20 will increase. If the data to be forwarded is small, the power consumption of the NB-IOT device 20 will increase. The power consumption will be reduced. Therefore, in order to reduce the power consumption of the NB-IOT device 20, this application fundamentally reduces the power consumption of the NB-IOT device 20 by reducing the amount of data sent by the device terminal 10, so the device terminal 10 will need The sent data is compared with the reference data in the first pre-stored database. If the data to be sent contains the same first data as the reference data in the first pre-stored database, the first data is converted into a reference data number of the corresponding reference data. , if the data that needs to be sent contains second data that is different from the reference data in the first pre-stored database, the second data is packaged and compressed into a data packet, and according to the comparison result, the data that needs to be sent is converted into the reference data number and /Or the data to be sent consists of data packets. Since the first data is converted into a reference data number, the NB-IOT device 20 only needs to forward the reference data number. There is no need to repeatedly send the first data, which reduces the cost of the NB-IOT device 20 The amount of data to be forwarded, thereby reducing the power consumption of the NB-IOT device 20; finally, the data to be sent is sent to the NB-IOT device 20, so that the NB-IOT device 20 forwards the data to be sent to the base station 30.

In some embodiments, step A2 includes:

If the data to be sent contains the same first data as the reference data in the first pre-stored database, convert the first data into the reference data number of the corresponding reference data;

If the data to be sent includes second data that is different from the reference data in the first pre-stored database, the second data is packaged and compressed into a data packet.

Specifically, the first embodiment: the data to be sent includes the first parameter of the first information, the second parameter of the first information, and the first parameter of the second information, wherein the first parameter of the first information and the first parameter of the first information The second parameter of is the same as the reference data in the first pre-stored database, and the corresponding reference data numbers of the first parameter of the first information and the second parameter of the first information in the first pre-stored database are N1M1 and N1M2, then the device terminal 10 Pack and compress the first parameter of the second information into a data packet, and then send the outgoing data composed of reference data numbers N1M1, N1M2 and data packets to the NB-IOT device 20. The NB-IOT device 20 only needs to Forwarding data packets and reference data numbers can effectively reduce the amount of data forwarded by the NB-IOT device 20, thereby reducing the power consumption of the NB-IOT device 20.

Second Embodiment, if the three data listed in the first embodiment are all the same as the reference data in the first pre-stored database, that is, the reference data numbers corresponding to the three data are N1M1, N1M2 and N2M1, then the equipment terminal 10 will The reference data numbers N1M1, N1M2 and N2M1 are directly sent to the NB-IOT device 20. The NB-IOT device 20 only forwards the reference data numbers without forwarding the reference data corresponding to the reference data numbers, which fundamentally reduces the forwarding time of the NB-IOT device 20. data volume, thereby effectively reducing the power consumption of the NB-IOT device 20.

In practical applications, the first pre-stored database is constantly updated. Every time the base station 30 receives a data packet to be sent, it means that the data packet does not have a reference data number. The base station 30 classifies the data packet and number, and then send it back to the device terminal 10 to update the first pre-stored database.

Among them, the equipment terminal 10 can be a terminal in the fields of smart grid, smart transportation, smart agriculture, industrial automation, fire protection, public safety, environmental meteorological monitoring, digital medicine, vehicle positioning, smart park, asset positioning, energy monitoring and other fields; the data that needs to be sent The reference data number is not limited to the above example N1M1, and can be set according to the data provided by the actual device terminal 10, and there is no specific limitation here.

In some embodiments, the reference data of the first pre-stored database is data stored in the historical data after being classified and numbered by the base station 30 and sent back to the device terminal 10 .

Specifically, when establishing the first pre-stored database, the base station 30 will classify and number the data forwarded by the NB-IOT device 20 from the device terminal 10. For example, the data received by the base station 30 includes the first parameter of the first information, the first The second parameter of the first information and the first parameter of the second information, then the base station 30 gives the information type a number N and the parameter type a number M. The reference data number corresponding to the first parameter of the first information is N1M1. The reference data number corresponding to the second parameter of the second information is N1M2, and the reference data number corresponding to the first parameter of the second information is N2M1. The base station 30 saves the classified and numbered data as new reference data and the corresponding reference data number to in the second pre-stored database, and send the new reference data and the corresponding reference data number to the NB-IOT device 20, so that the NB-IOT device 20 forwards the new reference data and the corresponding reference data number to the device terminal 10, by The device terminal 10 saves it to the first pre-stored database, so that when the device terminal 10 sends data next time, the data to be sent is compared with the reference data of the first pre-stored database, thereby reducing the transmission of repeated data, thereby reducing the cost of NB-IOT The power consumption of the device 20. In actual use, if the data received by the base station 30 contains data packets, the above classification and numbering process will continue to be repeated. As the use time of the device terminal 10 increases, the reference data of the first pre-stored database The more reference data numbers there will be, the more conducive to improving the probability of NB-IOT device 20 power saving. Among them, by classifying the data, when the base station 30 restores the data content according to the reference data number, it can first perform a preliminary screening of the reference data according to the information type, and then only needs to match the reference data of the same information type to query. Corresponding target data improves query efficiency.

In the second aspect, this application provides a method for reducing the power consumption of NB-IOT equipment. The method is applied to the base station 30 and includes the steps:

B1. Receive the data to be sent from the device terminal 10 forwarded by the NB-IOT device 20; the data to be sent consists of reference data numbers and/or data packets;

B2. When the data to be sent contains the reference data number, according to the reference data number, search the corresponding reference data in the second pre-stored database as the target data, replace the reference data number in the data to be sent with the target data, and use the target data and/or data packets constitute final data, and the final data is forwarded to the target terminal 40 .

Specifically, when all the data to be sent received by the base station 30 are data packets, the data packets are directly forwarded to the target terminal 40 as final data.

Among them, the reference data of the second pre-stored database is data saved after the base station 30 classifies and numbers the historically received data.

When the data to be sent includes a data packet, the data in the data packet is classified and numbered. For example, the data received by the base station 30 includes the first parameter of the first information, the second parameter of the first information and the third parameter of the second information. One parameter, then the base station 30 gives the information type a number N and the parameter type a number M. The reference data number corresponding to the first parameter of the first information is N1M1, and the reference data number corresponding to the second parameter of the first information is N1M2. The reference data number corresponding to the first parameter of the second information is N2M1. The base station 30 saves the classified and numbered data and the corresponding reference data number to the second pre-stored database, and sends it to the NB-IOT device 20 at the same time, so that the NB- The IOT device 20 forwards the reference data to the device terminal 10, and the device terminal 10 saves the reference data and the reference data number to the first pre-stored database, so that when the device terminal 10 sends data next time, the data to be sent is compared with the first pre-stored database. Comparison with the reference data of the database can reduce the transmission of repeated data, thereby reducing the power consumption of the NB-IOT device 20.

In some embodiments, step B1 further includes the following steps:

B11. Classify and number the data of the data packet;

B12. Save the numbered data as new reference data and the corresponding reference data number into the second pre-stored database, and send the new reference data and the corresponding reference data number to the NB-IOT device 20, so that the NB-IOT The device 20 forwards the new reference data and the corresponding reference data number to the device terminal 10 .

In some embodiments, after step B1, the step B1 is further included:

When the data to be sent includes a data packet, update the number of recordings of the received data packet in the preset time period before the current time, and determine whether the repetition rate of the data is lower than the preset threshold based on the updated number of recordings. (Can be set according to actual needs);

If the repetition rate is lower than the preset threshold, record the data of the data packet at the current moment, and do not execute steps B11 and B12;

If the repetition rate is not lower than the preset threshold, steps B11 and B12 are executed.

Specifically, the preset time period can be one month, or three months, or one quarter, and there is no specific limit. The repetition rate of the data refers to the number of times the data is sent by the device terminal 10 within the preset time period (i.e. The ratio of the number of repetitions) to the total number of times that the equipment terminal 10 sends the data to be sent within the preset time period. The repetition rate is expressed by the formula a/H, where a is the number of recording times of the data within the preset time period, and H is the preset time period. Assume the total number of times to receive data to be sent within a time period. For example, the number of records is 2, the total number is 10000, and the preset threshold is 0.01, then 2/10000=0.0002, that is, the repetition rate is lower than the preset threshold. It can be considered that the The occurrence of this type of data is accidental, and the probability of recurrence is small. There is no need to classify and number the data. The base station 30 also sends this type of data with a small probability of recurrence to the equipment terminal 10, and the equipment The terminal 10 records this type of data, and the data that the equipment terminal 10 needs to send contains this type of data, and directly sends this type of data to the NB-IOT device 20, so that the NB-IOT device 20 forwards it to the base station 30, and the base station 30 receives it. When this type of data is included in the data to be sent, this type of data will no longer be classified and numbered. If the repetition rate is not lower than the preset threshold, it needs to be classified, numbered, and saved, so that when the device terminal 10 sends repeated data, it only needs to send the corresponding reference data encoding to the NB-IOT device 20, and the NB -The IOT device 20 forwards the reference data encoding, thereby reducing the amount of data forwarded by the NB-IOT device 20, that is, indirectly reducing the power consumption of the NB-IOT device 20.

In some implementations, if the data of the data packet is not recorded for the first time, the first time of the data recorded at the current moment and the second time of the last time the data was recorded are obtained, and the length of time between the first time and the second time is determined. Is it greater than the preset time threshold? If the time length is greater than the preset time threshold (can be set according to actual needs), the data will be deleted and will not be saved in the future preset time. The base station will forward the data directly after receiving it. For the target terminal 40, the base station 30 can periodically delete some data that is almost never repeated, which is beneficial to reducing the burden on the base station 30.

In the third aspect, this application provides a system for reducing the power consumption of NB-IOT equipment, including: equipment terminal 10, NB-IOT equipment 20, base station 30 and target terminal 40;

The device terminal 10, NB-IOT device 20, base station 30 and target terminal 40 are connected in sequence;

The equipment terminal 10 is used to compare the data that needs to be sent with the reference data in the first pre-stored database, and convert the data that needs to be sent into data to be sent consisting of reference data numbers and/or data packets according to the comparison results, and sends it to NB- The IOT device 20 sends the data to be sent;

The NB-IOT device 20 is used to receive the data to be sent from the device terminal 10 and forward it to the base station 30;

The base station 30 is used to receive the data to be sent forwarded by the NB-IOT device 20. When the data to be sent contains a reference data number, based on the reference data number, the corresponding reference data is searched in the second pre-stored database as the target data, and the data to be sent is The reference data number in the data is replaced with target data, the final data is composed of the target data and/or the data packet, and the final data is forwarded to the target terminal 40, as shown in Figure 4.

Through the above settings, the amount of data forwarded by the NB-IOT device 20 can be reduced, thereby reducing the power consumption of the NB-IOT device 20 and more conducive to saving power.

In some embodiments, the base station 30 is also configured to, after receiving the data to be forwarded by the NB-IOT device 20, perform:

Classify and number data in packets;

Save the numbered data into the second pre-stored database as new reference data and the corresponding reference data number, and send the new reference data and the corresponding reference data number to the NB-IOT device 20;

The equipment terminal 10 is also configured to save the received new reference data and the corresponding reference data number to the first pre-stored database.

Through the above settings, the sending of repeated data can be reduced, which is beneficial to reducing the amount of data forwarded by the NB-IOT device 20, thereby effectively reducing the power consumption of the NB-IOT device 20.
