The technical solution of the present invention will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
The invention provides a feeder terminal converged communication method fusing Customer Premise Equipment (CPE), wherein the CPE is connected with a feeder terminal FTU through a serial port link, the CPE is connected with a master station side through a communication link, and the serial port link and the communication link form a converged communication link. The feeder terminal can comprise a feeder terminal mainboard, the customer premises equipment can comprise a customer premises equipment mainboard, and the feeder terminal mainboard and the customer premises equipment communicate at least through one serial port and are preferably set to be 2. The feeder line terminal is mainly used for monitoring the electric energy data and transmitting the electric energy data to the customer premises equipment, and the customer premises equipment encrypts the electric energy data and then sends the electric energy data to the master station side. Because the customer premise equipment processes the electric energy data and sends the electric energy data to the master station side, the data volume of the electric energy data sent by the feeder terminal to the customer premise equipment is different from that of the electric energy data sent by the customer premise equipment to the master station side. The master station side can comprise a server, and the server is connected with the client front-end equipment and receives and transmits data with the client front-end equipment.
The converged communication link is monitored through the following steps, as shown in fig. 1, the method provided by the invention specifically comprises the following steps:
step S110, obtaining an FTU data transmission quantity value of the serial port link in a first preset time period, where the first preset time period includes a first FTU transmission time point and a second FTU transmission time point. The FTU data transmission quantity value of a time period can be counted, the execution main body can be an MCU, and the FTU data transmission quantity value of the serial port link in a first preset time period is collected through the MCU. The first preset time period may be 10 seconds, 1 minute, 2 minutes, and so on. The first FTU transmission time point and the second FTU transmission time point may be any time points. For example, if the first preset time period is 10 seconds, the difference between the first FTU transmission time point and the second FTU transmission time point is 10 seconds. The first FTU transmission time point is 22:46:44 at 10/6/2021, and the second FTU transmission time point is 22:46:54 at 10/6/2021. The first preset time period comprises 22:46:44 at 6/10/2021, 22:46:45 at 6/10/2021, … … at 22:46:54 at 6/10/2021.
In the technical solution provided by the present invention, as shown in fig. 2, step S110 specifically includes:
step S1101, determining a first FTU transmission time point at intervals of a preset time period, where the first FTU transmission time point is a current time. The present invention determines that there is a certain regularity in the first FTU transmission time point, which may be 1 hour, 2 hours, 10 hours, etc. The invention can adjust the preset time period according to the current monitoring requirement and monitoring requirement, can lower the preset time period when having the monitoring requirement of higher frequency, and can increase the preset time period when having the monitoring requirement of lower frequency.
Step S1102, a second FTU transmission time point is obtained based on the first FTU transmission time point and a preset feeder terminal delay time. The feeder terminal deferral time in the present invention may be preset, and the feeder terminal deferral time is a numerical value, for example, the feeder terminal deferral time is 10 seconds, the first FTU transmission time point is 22:46:44 at 10 months and 6 days in 2021 year, and the second FTU transmission time point is 22:46:54 at 10 months and 6 days in 2021 year. The delay time of the feeder terminal can be adjusted according to requirements, and the longer the delay time of the feeder terminal is, the more accurate the monitoring accuracy is, but the larger the data processing amount is, so that the proper selection and adjustment are required according to actual scenes.
Step S1103 generates first preset time periods based on the first FTU transmission time point and the feeder terminal transmission time point, respectively, and obtains a data transmission quantity value at each time from the first FTU transmission time point to the second FTU transmission time point, to obtain an FTU data transmission quantity value. When the FTU data transmission quantity value is calculated, the data quantity transmitted at each moment and time point is calculated, and the FTU data transmission quantity value which is the sum of the data quantities of all the moments and time points in the first preset time period is obtained.
Step S120, obtaining an encryption delay time of the customer premises equipment, and generating a first CPE transmission time point and a second CPE transmission time point based on the encryption delay time, the first FTU transmission time point and the second FTU transmission time point, respectively. The client front-end equipment performs encryption processing after receiving the data transmitted by the feeder line terminal. Therefore, the feeder terminal transmits the target data to the client front-end device at the first time, and the client front-end device encrypts the target data and transmits the encrypted target data to the master station side at the second time. In order to ensure that the FTU data transmission quantity value and the CPE data transmission quantity value which are acquired by the serial port link and the communication link are the same batch of data when the method performs data comparison verification, the method performs offset on a first FTU transmission time point and a second FTU transmission time point according to encryption delay time to obtain the offset first CPE transmission time point and the offset second CPE transmission time point. Further ensuring that the monitoring result of the invention is more accurate.
In the technical solution provided by the present invention, step S120 specifically includes:
and acquiring the average transmission quantity of the feeder terminal corresponding to the FTU data transmission quantity value, and selecting the encryption delay time corresponding to the average transmission quantity of the feeder terminal in advance according to the average transmission quantity of the feeder terminal. Since the time consumption for encrypting the data with different data quantity values by the customer premise equipment is different, the average transmission quantity of the feeder terminal can be obtained according to the FTU data transmission quantity value, namely, the FTU data transmission quantity value is divided by the quantity of all the moments in the first preset time period, so that the average transmission quantity of the feeder terminal can be obtained. Different average transmission quantity of the feeder line terminal can be preset to correspond to different encryption delay times, and the encryption delay time can be selected according to the corresponding relation between the average transmission quantity of the feeder line terminal and the encryption delay time. For example, if the average transmission amount of the feeder terminal is 0 to 1mb, the corresponding encryption delay time is 0.1 second.
Calculating a first CPE transmission time point and a second CPE transmission time point by the following formulas, including:
Figure 382155DEST_PATH_IMAGE001
wherein the content of the first and second substances,
Figure 564744DEST_PATH_IMAGE002
for the first CPE transmission point in time,
Figure 295939DEST_PATH_IMAGE003
for the second CPE transmission point in time,
Figure 289303DEST_PATH_IMAGE004
for the first point in time of FTU transmission,
Figure 965004DEST_PATH_IMAGE005
for the second point in time of FTU transmission,
Figure 170857DEST_PATH_IMAGE006
in order to encrypt the delay time,
Figure 428663DEST_PATH_IMAGE007
is a delay correction value.
The invention calculates the transmission time point of the first CPE and the transmission time point of the second CPE according to the encryption delay time
Figure 779879DEST_PATH_IMAGE006
The delay correction value is set for the encryption delay time to meet more encryption scenes, for example, the delay correction value is set for the encryption delay time in some cases when the encryption is more complicated
Figure 490346DEST_PATH_IMAGE007
The value of (2) can be adjusted to be larger, so that the delay time is increased, and the data monitoring is more accurate.
For example, say that
Figure 100002_DEST_PATH_IMAGE017
For 2 seconds, the first FTU transmission time point is 22:46:44 at 10/month and 6/day 2021, the second FTU transmission time point is 22:46:54 at 10/month and 6/day 2021, then the first CPE transmission time point is 22:46:46 at 10/month and 6/day 2021, and the second CPE transmission time point is 22:46:56 at 10/month and 6/day 2021.
Step S130, respectively generating a second preset time period based on the first CPE transmission time point and the second CPE transmission time point, and acquiring a CPE data transmission quantity value of the communication link in the second preset time period. The invention can reversely deduce the second preset time period after obtaining the transmission time point of the first CPE and the transmission time point of the second CPE. Then the second preset time period is 22:46:46 at 10/6/2021 to 22:46:56 at 22: 6/10/2021, and the time points included in the second preset time period are 22:46:46 at 10/6/2021, 22:46:47, … … at 22:46:56 at 10/6/2021. After the second preset time period is obtained, the data transmission quantity value corresponding to each time point in the second preset time period is collected, and the CPE data transmission quantity value is obtained.

The invention can carry out linear fitting on all historical FTU data transmission quantity values and CPE data transmission quantity values to obtain a linear formula and a linear model. The invention can calculate the CPE data pre-measurement value more accurately, and fully considers all CPE data transmission quantity values and FTU data transmission quantity values in the history.
According to the technical scheme provided by the invention, the FTU data transmission quantity value is input into a pre-fitted linear model to obtain a CPE data pre-measurement value, and if the absolute value of the difference value between the CPE data transmission quantity value and the CPE data pre-measurement value is greater than a standard value, the step of sending reminding information to the master station side comprises the following steps:
and inputting the FTU data transmission quantity value serving as an independent variable into the linear formula to obtain a CPE data pre-measured value serving as a dependent variable. The invention inputs the FTU data transmission quantity value into a linear formula, and further can obtain a CPE data pre-measurement value.
And determining the absolute value of the CPE data transmission quantity value after the difference between the CPE data transmission quantity value and the CPE data prediction quantity value is calculated, and sending reminding information to the master station side if the absolute value is greater than a standard value. Since the difference between the CPE data transmission value and the CPE data prediction value may be a positive number or a negative number, the present invention needs to determine the absolute value after obtaining the difference between the CPE data transmission value and the CPE data prediction value. The difference may be the CPE data transmission value minus a CPE data pre-measurement value.
The technical scheme provided by the invention further comprises the following steps:
and acquiring the FTU data transmission quantity value of the serial port link at the current moment. The invention also can monitor the FTU data transmission quantity value of the serial port link in real time.
And determining the applicable baud rate of the client front-end equipment and the master station side based on the FTU data transmission quantity value at the current moment.
And inputting the FTU data transmission quantity value at the current moment into a linear formula of a linear model to obtain a CPE data pre-measured value. The invention can input the FTU data transmission quantity value collected in real time into a linear formula to obtain a CPE data pre-measurement value, wherein the CPE data pre-measurement value can be the CPE data pre-measurement value of the CPE data needing to be transmitted at the next moment.
And obtaining a magnitude section to which the CPE data prediction measurement value belongs, and determining the baud rate corresponding to the magnitude section as an applicable baud rate, wherein a magnitude interval in each magnitude section is preset, and the baud rate corresponding to each magnitude section is preset. The larger the baud rate, the higher its data transmission capacity, but the higher its power consumption is. The invention can dynamically adjust the baud rate of the client front-end equipment according to the data transmission quantity at the next moment. For example, the interval of the first magnitude segment is

，
Figure DEST_PATH_IMAGE019
And
Figure 811125DEST_PATH_IMAGE020
respectively, different quantitative values, the CPE data pre-measured value is
Figure DEST_PATH_IMAGE021
And is and
Figure 486957DEST_PATH_IMAGE022
then the CPE data prediction measurement belongs to the first measurement segment at this time. Each magnitude segment has a different baud rate.
And judging the current baud rate of the client front-end equipment at the current moment, and converting the current baud rate of the client front-end equipment into the applicable baud rate if the current baud rate is different from the applicable baud rate. If the current baud rate is different from the applicable baud rate, the baud rate of the client front-end equipment at the current time is proved to be not the optimal baud rate, so that the adjustment is needed at the moment to ensure that the client front-end equipment achieves the most energy-saving working mode.
The technical scheme provided by the invention further comprises the following steps:
and if the CPE data pre-measurement value is judged to be larger than the quantity values corresponding to all the quantity value sections, reminding information is output to the master station side. When the CPE data pre-measurement value is greater than the quantity values corresponding to all the quantity value segments, it is proved that the quantity value of the data to be transmitted by the customer premise equipment is too large next, and at this time, the customer premise equipment may not perform effective processing, so that a prompt message needs to be output. Generally, the feeder terminal does not transmit information of a data amount value that the customer premises equipment cannot effectively process, but when the feeder terminal has a problem, it may suddenly transmit a large amount of data.
An embodiment of the present invention further provides a feeder terminal converged communication device converged with a client front-end device, where the client front-end device is connected with the feeder terminal through a serial link, the client front-end device is connected with a master station side through a communication link, and the serial link and the communication link form a converged communication link, and the converged communication link is monitored through the following modules, as shown in the schematic structural diagram shown in fig. 3, including:

The integrated circuit board is embedded and fused, belongs to communication among 2 independent circuit boards, adopts a serial port line connection mode, and does not adopt an integrated circuit board integration mode. Therefore, the situation that the single serial port channel is abnormal in communication is considered, the situation that the single serial port channel is abnormal in communication is avoided from influencing the working stability of the fusion device, and one standby communication serial port is additionally added between the boards.
After the devices are fused, the customer front equipment board card informs the MCU of the fusion device of the link state. The MCU side communicates with the feeder terminal device module, informs the link state of the MCU side and reports the state to the main station side. If the link state is poor, the remote measuring, remote signaling and remote control functions of the feeder line terminal are controlled, the remote measuring and remote signaling functions are reserved, and the remote control functions enter a limited state (recovery after the communication link is normal). The master station side can also actively inquire the link state of the fusion device in a polling mode and judge through the response state of the fusion device. When the link is abnormal, the fusion device adds the acquired information such as analog quantity, switching value and the like and the timestamp to the information and keeps the information in the storage medium. And after the link is recovered, uploading the stored information to the master station side.

And the two-way window is in a switching working mechanism, and the single-way abnormal report is carried out on the master station side for problem troubleshooting. If the two paths are abnormal, the fusion device realizes local storage of data such as switching value or analog quantity, and the MCU informs the master station side of the fault information of the two paths of serial ports through the quantum encryption tunnel.
After the fusion device detects that the communication link is abnormal, the remote signaling and remote measuring functions are still reserved, the remote control function is closed, the master station side is informed (if the master station side cannot be informed, the function is closed locally, the master station side judges the state of the equipment according to the overtime information), if the serial port communication is abnormal, the MCU sends the abnormal state to the master station side, and the three-remote function is in an abnormal or unavailable state. Analog quantity, switching value and other information collected by the feeder terminal are locally retained in the storage medium.
According to a CPE board card communication interface such as an ipex interface, an ipex-sma feeder line is used for extension, a hole is formed in a shell of the fusion device, and a waterproof connector is used for installation.

And determining the number of the openings according to the requirement of the number of the multi-antenna of 5G. And determining the position of the antenna interface by considering the available area of a plurality of feeder lines and the shell in the fusion device and the requirement of the isolation degree of the antenna.
