Fig. 3 is a flow chart of a control method of a data acquisition system based on a Beidou director according to an embodiment of the application. As shown in fig. 3, the method comprises the steps of:

Step S201, a second Beidou director acquires a target ID of a target user machine, wherein the target user machine is a user machine which fails to package Beidou short messages by the first Beidou director;

Specifically, the data acquisition end packages the acquired data according to the Beidou short message format and sends the packaged data to the first Beidou command machine and the second Beidou command machine, the first Beidou command machine receives the short message information of the subordinate user machine of the data acquisition end and analyzes the short message information, the data are packaged according to the sub-package number, the data are sent to the server for decompression through the network after the successful package is completed, if the package is failed, the data are discarded, the subordinate user machine ID is sent to the second Beidou command machine, and the second Beidou command machine receives the target ID of the target user machine.

Specifically, aiming at the problem that the single communication capacity of the Beidou short message service is limited, the Beidou short message can be sent by using a data compression and data packetization mode in the scheme.

Specifically, the judgment as to whether the data has failed to be packed may be performed in the following manner: the sequence numbers of the data packets are not ordered according to a preset ordering mode, the first difference value between the Mth sequence number and the Mth-1 sequence number is not equal to the second difference value between the Mth sequence number and the Mth+1th sequence number, the end zone bit is not acquired, the data packets cannot be analyzed normally, the time length of the data packets which are not received is longer than or equal to the target time length, and the packet grouping failure can be determined when at least one of the conditions is met.

Step S202, the second Beidou director establishes communication connection with the target user machine in a point-to-point communication mode, and requests the target user machine to resend the Beidou short message;

specifically, the second Beidou director performs point-to-point communication with a part of subordinate user machines (i.e. the IDs of the user machines with failed packet), and requires the subordinate user machines to retransmit the power grid data (which may also be referred to as electric meter data herein).

Step 203, the second Beidou director receives the Beidou short message retransmitted by the target user machine, and performs packet processing on the retransmitted Beidou short message;

Specifically, after receiving the instruction of the second Beidou director, the subordinate user machine reads the buffer area to carry out data cycle retransmission, and after receiving the data of the target user machine, the second Beidou director analyzes the data and carries out packet combination again.

And step S204, the second Beidou director sends packet success information to the target user machine under the condition of successful packet formation, and reports the abnormality of the target user machine to a server under the condition of packet formation failure.

Specifically, if the grouping is successful, a short message with the message content of 0 is sent, and the user machine stops sending after receiving the message; if the grouping is not successful in the appointed time, recording the report abnormality of the user machine ID.

Through this embodiment, through two big dipper commander collaborative works, first big dipper commander is used for normal work, if the group package has failed, then adopts the second big dipper commander to be responsible for unusual communication (send data and group package data), and first big dipper commander continues to be responsible for other communication transmission and need not go to be responsible for unusual communication again, consequently adopts the mode of two machines collaborative works, can improve the collection efficiency and the sending efficiency of electric wire netting message.

The Beidou system allows the Beidou command machine to simultaneously receive information of subordinate machines by utilizing the monitoring function, and can simultaneously send communication information to subordinate users at a time.

Specifically, as shown in fig. 4, the first Beidou director and the Beidou user machine form a conventional single director user group, the user machine is preset with an ID of the first Beidou director, and a power grid data message is sent to the first Beidou director in a point-to-point manner; on the basis of the single director user group, the first Beidou director and the user machine are collectively used as subordinate machines of the second Beidou director.

In addition, the communication all-in-one machine can compress power grid data by adopting an LZW algorithm, unpack the compressed data according to the single message length of the Beidou card, and add a corresponding packet header.

The first Beidou director can simultaneously send the same information to all subordinate computers at one time by utilizing the general broadcasting function, realize the functions of batch acquisition, batch timing and the like, and also can send specific information to the appointed user machine point to point according to the user machine ID, such as acquisition position, data retransmission and the like.

According to the scheme, the cooperative strategy of the two Beidou command machines is adopted, the same power grid data is received in a non-simple mutually independent mode, the frequency resources of the two command machines are fully utilized, and the transmission efficiency of the acquisition system is improved.

In the specific implementation process, the second Beidou director acquires the target ID of the target user machine, and the method can be realized by the following steps: the second Beidou director acquires the target ID of a first type, wherein the target ID of the first type is the target ID of the target user machine with abnormal sequence numbers of data packets of the first Beidou director group; the second Beidou director acquires the target ID of a second type, wherein the target ID of the second type is the target ID of the target user machine, which is still not received by the target user machine after polling, and the time length of which the first Beidou director does not receive the data sent by the target user machine reaches the target time length and requests the target user machine to resend the data in a point-to-point communication mode.

In the scheme, if the first Beidou director fails to send the target ID to the second Beidou director due to packet failure, the target ID is marked as a first type, if the first Beidou director does not receive the short message information of the user machine for a long time, the first Beidou director still does not receive the short message information of the user machine after adopting a point-to-point communication mode, then the target ID is sent to the second Beidou director, the target ID is marked as a second type, and the second Beidou director receives the ID sent by the first Beidou director and has the type, and then corresponding processing can be carried out according to the type.

Specifically, the first Beidou director uploads the user machine ID to the user machine in the second Beidou director due to package failure, and the user machine is marked as '1' type; after the first Beidou director does not receive short message messages for a long time, checking subordinate list messages, recording subordinate user machines which do not receive the messages yet, and sending retransmission commands to the subordinate user machines in a point-to-many mode; and after polling for one time, the subordinate user machines which do not receive the message still report the second Beidou director machine, and the second Beidou director machine is marked as '2'.

The Beidou short message is affected by environmental factors around the equipment under the actual application condition, the condition of sending failure often occurs, and the short message communication is receipt-free, so that whether the message is received by the opposite party can not be determined.

In the specific implementation process, after the second Beidou director acquires the target ID of the target user machine, the method further comprises the following steps: under the condition that the type of the target ID is the first type, the second Beidou director establishes communication connection with the target user machine in a point-to-point communication mode, and requests the target user machine to resend the Beidou short message; and under the condition that the duration of the target user machine which does not receive the Beidou short message reaches the target duration, the second Beidou director changes the type of the target ID into a second type.

In the scheme, the second Beidou director adopts point-to-point communication to the user machine with the target ID of the first type, if the reply of the user machine is not received for a long time, the ID of the user machine is changed into the second type, and the user machine of the first type is actually caused by interference, and if the reply is not yet carried out for a long time, the user machine type can be accurately further determined through the scheme.

Specifically, the second Beidou director sequentially adopts point-to-point communication for the '1' subordinate user IDs, and if the short message of the subordinate user IDs is not received within a specified time, the subordinate user IDs are changed into '2'.

In the specific implementation process, after the second Beidou director acquires the target ID of the target user machine, the method further comprises the following steps: under the condition that the type of the target ID is the first type, the second Beidou director establishes communication connection with the target user machine in a point-to-point communication mode, and requests the target user machine to resend the Beidou short message; reporting the abnormality of the target user machine to the server by the second Beidou director when the number of packet failure times is greater than or equal to the first preset number of times; and the second Beidou director uploads the composed data packet to the server under the condition that the grouping is successful.

In this scheme, the target ID may be caused by interference or packet loss, if the first type of user machine still fails to group packets after repeating data, it is abnormal for the user machine, if the group packets succeed, it is uploaded to the server, so that the corresponding policy can be executed after determining the cause of the data transmission failure more accurately.

Specifically, the second Beidou director sequentially adopts point-to-point communication to the '1' subordinate user ID, positions the sub-packet number with failed packet grouping, performs a designated sub-packet retransmission instruction on the subordinate user, successfully groups the packets and sends the sub-packet number to the server; if the retransmission still fails to be packed more than k times (three times, five times or other times), the server is reported that the subordinate user machine is abnormal.

In the specific implementation process, after the second Beidou director acquires the target ID of the target user machine, the method further comprises the following steps: under the condition that the type of the target ID is the second type, the second Beidou director establishes communication connection with the target user machine in a mode of random point-to-point communication through irregular time; reporting the abnormality of the target user machine to the server by the second Beidou director when the communication failure frequency between the second Beidou director and the target user machine is greater than or equal to a second preset frequency; and under the condition that the second Beidou director is successful in communicating with the target user machine, requesting the target user machine to resend the Beidou short message.

In the scheme, the target ID is of a second type, namely the user machine is out of connection, if the user machine is out of connection, communication connection is established with the user machine in a mode of randomly penetrating point-to-point communication, if the user machine still cannot communicate with the user machine after multiple times of connection, the user machine is abnormally reported to a server, and if the connection is successful, the user machine is requested to resend data, so that a corresponding strategy can be executed after the reason of the data transmission failure is accurately determined.

Specifically, the second Beidou director adopts irregular random interpenetration of point-to-point communication for the '2' subordinate user machine ID, and if k times of point-to-point communication still fail, the server is reported that the subordinate user machine is abnormal.

Random interleaving of point-to-point communication means that transmission and reception of information are not performed at fixed time intervals or sequences during communication, but point-to-point communication is performed at different time points and positions at random.

For example, in a wireless sensor network, data transmission and sharing are required between sensor nodes. The time and location of the transmission cannot be predetermined due to the difference in location and environmental conditions between the nodes. Thus, in this case, the communication between the sensor nodes is an sporadic random interleaving point-to-point communication.

For example, in the context of a mobile internet, users communicate and data transfer via cell phones and other devices. The time and location of the communication may also vary randomly due to uncertainty in the location and movement status of the user. Thus, communication between users is random interleaving point-to-point communication at random.

Therefore, the reasons of transmission failure of the Beidou short message can be identified, and the reasons of failure, namely the first type and the second type, are corresponding, the first type is caused by data packet loss or interference, the second type is caused by user machine disconnection, so that the probability of false alarm can be reduced, and the corresponding strategy is executed after the reasons of data transmission failure are accurately determined.

The scheme classifies abnormal subordinate user machines, avoids the problem of abnormal short Beidou short message transmission due to external environment influence, and reduces the false alarm probability.

In some embodiments, the method further includes the following steps after the second Beidou director sends the packet success information to the target user machine when the second Beidou director fails to packet, and reports the target user machine abnormality to the server when the second Beidou director fails to packet: the second Beidou director acquires new application information of the acquisition end under the condition that a new acquisition end is accessed to the system, wherein the application information at least comprises a local ID; the second Beidou director checks the application information to obtain a check result; the second Beidou director sends verification success information to the new acquisition end under the condition that the verification result representation passes verification; and discarding the application information of the new acquisition end by the second Beidou director under the condition that the verification result representation fails to pass the verification.

In the scheme, if the second Beidou director receives the information of the new acquisition end to be accessed to the system, the application information of the new acquisition end can be checked, if the new acquisition end passes the check, the system is accessed, and if the check fails, the information is discarded, so that the system is ensured to have a safe access mechanism, and the system has flexibility.

Specifically, the second Beidou director further receives and processes a new acquisition terminal access application, the new acquisition terminal sends the local ID, the position, the collector ID, the application group and other contents to the second Beidou director, the second Beidou director performs rationality verification on the information, if the verification passes, the second Beidou director sends short message information of a success indication to the acquisition terminal, and the user ID of the short message information is written into a subordinate group where the second Beidou director is located; otherwise, the short message is discarded. According to the Beidou user group management rule, the new user group participated by the second Beidou director does not have the general broadcasting function any more, namely the second Beidou director can only send instructions to the user machine point to point. And when the subordinate number of the Beidou director does not reach the upper limit, writing the subordinate number of the Beidou director into a subordinate user list of the first Beidou director at intervals. And the user machine transmits the power grid data to the first Beidou director machine preferentially.
