The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In one aspect, as shown in fig. 1, an embodiment of the present invention provides a method for communicating a metering device, including:
s120: acquiring information of each metering instrument in a target range;
s140: dividing the metering instruments into batches according to a preset rule according to the information of the metering instruments;
s160: and distributing different communication time for the metering instruments of different batches, wherein the communication time is used for indicating each metering instrument to upload metering data at corresponding time.
The target range refers to an area range meeting a specific condition, and may be a certain area concentrated in a geographical location, or a signal coverage range of a certain signal base station, and the like. The information of the meter is information for identifying the meter, and may be, for example, a number of the meter or a user ID corresponding to the meter, and the information of each meter is different and unique. The metering device is a metering device with functions of collecting and uploading metering data, and may be various metering devices, such as a gas meter. The preset rule is a rule that each meter can be divided into a plurality of batches. The communication time (corresponding time) refers to the uploading time of the metering data distributed to the metering device, and refers to the uploading time of a specific metering data corresponding to the metering devices of the same batch.
Specifically, the information of each metering instrument is acquired from the target range, batch processing is carried out according to the information of each metering instrument, each metering instrument is divided into a plurality of batches according to a preset rule, the same metering data uploading time is distributed to the metering instruments of the same batch, and the metering data are uploaded to a server or a remote terminal when the metering instruments of the batch reach the corresponding metering data uploading time. And metering instruments in different batches are arranged to upload metering data at different communication times, so that the load of a signal base station at the same time is reduced, the communication success rate is ensured, and the communication quality is further ensured. And different communication time is allocated to metering instruments of different batches, so that network resources can be utilized in different time periods, and the utilization rate of the network resources is improved. On the other hand, the communication in batches can reduce the configuration requirements on network resources such as signal base stations, network bandwidth and the like, so that the communication cost can be reduced.
In one embodiment, as shown in fig. 2, the information of the meters includes the numbers of the meters, and the step of grouping the meters into batches according to the preset rule includes:
s141: dividing the metering instruments with the same number in the serial numbers of the metering instruments into the same batch.
The number of each metering device is a unique number of each metering device, and is identity information capable of distinguishing each metering device. The corresponding digits refer to the same digits in each meter number, such as the ones of each meter number or the tens of each meter number.
Specifically, the information of the metering instruments includes the serial numbers of the metering instruments, the metering instruments with the same corresponding digits in the serial numbers of the metering instruments are divided into the same batch, and the corresponding communication time is distributed to the metering instruments of each divided batch, so that the metering instruments of the same batch upload metering data at the same time, and the metering instruments of different batches upload metering data at different times.
In one embodiment, the step of dividing the meters with the same number in the number of each meter into the same batch comprises:
dividing the metering instruments with the same number in the serial numbers of the metering instruments into the same batch;
or dividing the metering instruments with the same number and tens number in the serial numbers of the metering instruments into the same batch.
Specifically, the method for dividing the metering devices into batches may be that the metering devices with the same ones in the serial numbers of the metering devices are divided into the same batch, and a communication time is allocated to the metering devices of the batch. For example, if the meters are gas meters, n gas meters may be divided into 10 batches (10 batches, with each having a single digit of 0 to 9, etc.) by dividing the gas meters having the same single digit in the number of the gas meters into the same batch. Optionally, the metering devices with the same ones and tens digits in the serial numbers of the metering devices can be divided into the same batch, and a communication time is allocated to the metering device of the batch, so that the metering devices of the batch can upload metering data in the allocated communication time. For example, if the meters are gas meters, if n gas meters are set to have the same batch of meters having the same ones and tens, the n gas meters can be divided into 100 batches (100 batches for each of the ones 00 to 99).
In one embodiment, the method further comprises the following steps:
s130: acquiring the total number of the metering instruments according to the information of each metering instrument;
s131: selecting the batch times according to the following formula according to the total number of the metering instruments:
n/N≤p≤T/t
wherein p is the batch times, p is a positive integer, N is the total number of the metering instruments, N is the maximum number of devices which are allowed by the signal base station and are simultaneously connected, T is the longest allowed time for all the metering instruments to complete communication, T is the time required by the communication of a single metering instrument, and T is more than or equal to T.
For the selection of the batch times, the network condition and a specific communication requirement are comprehensively considered. Optionally, the total number of the metering instruments is obtained, and the batch times are selected according to the total number of the metering instruments, so that the batch p meets the following conditions:
n/N≤p≤T/t
wherein, p is the batch times, N is the total number of the metering instruments, N is the maximum number of devices which are allowed by the signal base station and are simultaneously connected, T is the longest allowed time for all the metering instruments to complete communication, and T is the time required by the communication of a single metering instrument. For example, if N is 1000 and N is 100, the batch number p should not be less than N/N10, T is 2min and T is 200min, the batch number p should not be greater than T/T100. In summary, the gas meters with the same serial number and the same number can be set as the same batch, and the gas meters are divided into 10 batches for peak communication at different times. The number ones and tens numbers can be set to be the same in the same batch, and the gas meter can be divided into 100 batches for peak-off communication at different times.
Therefore, the number of the metering instruments accessed to the signal base station at the same time is not more than the maximum number of the devices which are allowed by the signal base station and connected at the same time, the success rate of network communication is guaranteed, on the other hand, all the metering instruments can be guaranteed to complete communication within the longest allowed time of one-time communication of all the metering instruments, and the integrity of metering data is guaranteed.
In one embodiment, the communication time interval between two adjacent batches of meters is constant.
In order to better distribute network resources, after each metering instrument is divided into batches, different communication time is distributed for each batch of metering instruments, the communication time interval of the metering instruments of two adjacent batches is a fixed value, namely, metering data are uploaded by one batch of metering instruments at the current time node T0, and then metering data are uploaded by the next batch of metering instruments at the interval time delta T, namely, at the time of T0 plus delta T, so that the uploading time of the metering instruments of each batch can be uniformly distributed, and the reasonable utilization of network resources is facilitated.
In one embodiment, the information of the gas meter comprises information of the gas meter.
In the aspect of gas, along with the technical development of gas meters, the intelligent gas meters are mostly adopted to realize the metering statistics of the gas use conditions of all users. Specifically, the information of each gas meter in the target range is obtained, and then, according to the information of each gas meter, each gas meter is divided into batches according to a preset rule. For example, the serial numbers of the gas meters are obtained, the gas meters with the same serial number are divided into the same batch, a communication time is allocated to the gas meters, and the communication time of the metering meters in different batches is guaranteed to be different, so that the gas meters can upload metering data in the corresponding communication time, and peak-to-peak communication is realized.
