It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Also, unless explicitly described, the word "comprise" and variations such as "comprises" or "comprising", will be understood to imply the inclusion of stated elements but not the exclusion of any other elements.
It should be noted that the terms "first", "second", and the like in the description and claims of the present invention and the accompanying drawings are used for distinguishing different objects, and are not used for limiting a specific order. The following embodiments of the present invention may be implemented individually, or in combination with each other, and the embodiments of the present invention are not limited in this respect.
In addition, the following embodiments of the present invention may be implemented individually, or may be implemented in combination with each other, and the embodiments of the present invention are not limited in this respect.
The first embodiment is as follows:
fig. 1 is a flowchart of a detection method for an encrypted communication apparatus according to an embodiment of the present invention. The detection method of the encryption communication device is applied to the encryption communication device, and as shown in fig. 1, the detection method of the encryption communication device comprises the following steps:
step S101, receiving first message data sent by a distribution network main station.
Step S102, caching the first message data and detecting whether the self-loop function is configured.
Specifically, after receiving a data packet (i.e., the first message data) sent by the distribution network master station, the encryption communication device sends the data packet to an encryption chip built in the encryption communication device to decrypt the data packet, caches the decrypted message, and detects whether the encryption communication device is configured with a self-loop function. The data packet sent by the distribution network master station to the encryption communication device is generally a 101 message.
And step S103, if the detection result is yes, copying the first message data to obtain second message data.
And step S104, returning the second message data as a response message to the distribution network main station, so that the distribution network main station determines whether the communication state of the encrypted communication device is normal or not according to the received response message.
Specifically, if the detection result is yes, indicating that the self-loop function of the encryption communication apparatus is turned on, it is necessary to verify whether the communication state of the encryption communication apparatus is normal, the encryption communication device will send the decrypted first message data to the distribution automation terminal connected with the encryption communication device through the serial port RS232, such as a DTU (Data Transfer Unit), a TTU (distribution Transformer monitoring Terminal), an FTU (Feeder monitoring Terminal), etc., meanwhile, the encryption communication device can copy the first message data just sent by the data transmission terminal TX of the serial port RS232 to obtain the second message data, and the second message data is encrypted by the encryption chip and then returned to the distribution network main station as a response message, so that the distribution network master station determines whether the communication state of the encrypted communication device is normal or not according to the received response message.
After the distribution network master station receives the response message, the first message data and the response message can be compared by a worker at the side of the distribution network master station, or the first message data and the response message can be automatically compared by the distribution network master station, and whether the communication state of the encryption communication device is normal or not is determined according to the comparison result.
It should be noted that, in the process of actually detecting the communication state of the encryption communication device, a worker on the encryption communication device side to some extent may also determine whether the communication state of the encryption communication device is normal by determining whether the encryption communication device can receive the first message data sent by the distribution network master station and successfully returning the response message to the distribution network master station, which is not described herein again.
In the embodiment of the invention, because the encryption communication device is usually arranged in a high tower and other places with inconvenient wiring, once a fault occurs, a worker needs to arrive at the site to change the serial port wiring mode of the encryption communication device to realize the detection of the communication state of the encryption communication device, and the serial port wiring of the encryption communication device is more, so that a certain time is needed for finding the corresponding wiring and changing the corresponding wiring. By using the detection method of the encrypted communication device provided by the invention, for the communication encryption device which is installed on the site, the communication state can be detected by the method as long as the communication connecting line is connected to the encrypted communication device on the site, and for the encrypted communication device which is installed on the site, the encrypted communication device can be detected in advance by using the method under the environment of stable indoor network, and then the detected encrypted communication device is brought to the site for installation, so that the problem that the detection is not facilitated due to environmental factors such as unstable network and the like under the outdoor environment is avoided, meanwhile, the working efficiency of workers is improved, the working time is saved, a certain operation and maintenance cost is saved, and the problem that equipment needs to be replaced by working to and fro at the site when the fault is detected on the site is avoided.
The communication state is judged by setting the self-loop function for the encryption communication device, the technical problem that the encryption communication device arranged at a position difficult to be connected is disassembled to be detected when the encryption communication device arrives at the site in the prior art is solved, the communication state of the encryption communication device can be automatically detected, the purpose of detecting the communication state without changing the serial port connection of the encryption communication device on the site is achieved, and the technical effects of effectively improving the working efficiency of operation and maintenance personnel, saving the working time and saving the operation and maintenance cost are realized.
Optionally, in step S101, before receiving the first message data sent by the distribution network master station, the detection method further includes:
sending dialing request information to encryption equipment on a network distribution main station side to establish a communication tunnel;
and initiating a TCP connection request to the front-end equipment of the distribution network main station to establish TCP connection.
Specifically, the encryption communication device obtains an IP address through dial-up networking, and then is connected with encryption equipment on the network distribution main station side to establish an encryption communication tunnel; then, the encryption communication device initiates a Transmission Control Protocol (TCP) connection to the front-end device of the distribution network main station, so as to establish a TCP connection with the front-end device of the distribution network main station; and finally, realizing data transmission between the distribution network main station and the encryption communication device through the established TCP protocol connection and the encryption communication tunnel.
Optionally, in step S102, after the first packet data is cached, the detection method further includes:
and transmitting the first message data to a device to be protected through a serial port.
Specifically, the serial port may be a common serial interface such as RS232, and the device to be protected refers to a distribution network automation terminal connected to the encryption communication device, such as a DTU, a TTU, a FTU, and the like, and the communication connection between the distribution network automation terminal and the distribution network master station needs to be transferred through encryption or decryption by the encryption communication device.
Optionally, the detection method further includes:
if the detection result is negative, only the received first message data is transmitted to the device to be protected through the serial port, and no response message is returned to the distribution network master station.
Specifically, if the result that whether the encryption communication device detects that the self-loop function is configured is negative, it indicates that whether the communication state of the encryption communication device is normal does not need to be verified currently, and therefore the self-loop function of the encryption communication device is not started, the encryption communication device only needs to decrypt the received first message data transmitted by the distribution network master station and transmit the decrypted first message data to the device to be protected connected with the encryption communication device through the serial port, and does not return a response message to the distribution network master station.
Fig. 2 is a flowchart of another method for detecting an encrypted communication device according to an embodiment of the present invention, and the method for detecting an encrypted communication device is specifically described below with a specific embodiment.
Illustratively, referring to fig. 2, the detection method of the encrypted communication device implements the following specific steps:
step S201, the encryption communication device dials up to the network to obtain an IP address, connects with the encryption equipment at the network distribution main station side, and establishes an encryption communication tunnel.
And S202, the encryption communication device initiates TCP connection, connects the preposed equipment of the distribution network main station and establishes TCP connection.
Step S203, the encryption communication apparatus receives the 101 message (i.e. the first message data) transmitted by the distribution network master station, writes the received 101 message into the cache, and checks whether the self-loop function is enabled.
Step S204, if the detection result is that the self-loop function is started, the message 101 is sent to the distribution network automation terminal through the serial port, and a copy of the message (namely, the second message data) sent to the distribution network automation terminal through the serial port is encrypted by the encryption chip and then sent to the distribution network master station.
Step S205, if the detection result is that the self-loop function is not enabled, only the 101 message is sent to the distribution automation terminal through the serial port, and no response message (i.e. the second message data) is returned to the distribution network master station.
In step S206, the operation and maintenance personnel determines whether the communication state of the encryption communication device is normal according to whether the message received by the encryption communication device (i.e. the message sent by the distribution network master station to the encryption communication device) is completely consistent with the message returned by the encryption communication device received by the distribution network master station.
Step S207, if the messages are completely consistent, the configuration and operation of the communication channel and the encryption communication device are normal.
Step S208, if the messages are not consistent, the configuration of the communication channel or the encryption communication device is abnormal.
Example two:
fig. 3 is a flowchart of another method for detecting an encrypted communication device according to an embodiment of the present invention. The detection method of the encryption communication device is applied to a distribution network main station, and as shown in fig. 3, the detection method of the encryption communication device specifically comprises the following steps:
step S301, the first message data is sent to the encryption communication apparatus.
Specifically, after the encryption device on the side of the distribution network master station receives the dialing request information sent by the encryption communication device and establishes a communication tunnel with the dialing request information, and the front-end device of the distribution network master station receives the TCP connection request sent by the encryption communication device and establishes a TCP connection with the TCP connection request, the distribution network master station sends first message data to the encryption communication device.
Step S302, receiving a response message returned by the encrypted communication device, where the response message is second message data obtained after the encrypted communication device copies the first message data.
Specifically, after the encryption communication device receives the first message data, if it is necessary to verify whether the communication state of the decryption communication device is normal, that is, the self-loop function of the encryption communication device is started, the encryption communication device copies the first message data to obtain the second message data, and returns the second message data to the distribution network master station as a response message.
Step S303 determines whether the communication state of the encrypted communication apparatus is normal based on the received response message.
Optionally, the step S303 of determining whether the communication state of the encrypted communication apparatus is normal based on the received response message includes:
comparing whether the first message data and the response message are completely consistent;
if the communication state is consistent with the preset communication state, the communication state of the encryption communication device is determined to be normal.
Specifically, after the distribution network master station receives the response message, whether the first message data and the response message are completely consistent or not is compared, if so, it is proved that the configuration operation of the communication channel of the encryption communication device and the configuration operation of the encryption communication device are normal, and if not, it is proved that the configuration operation of the communication channel of the encryption communication device or the configuration operation of the encryption communication device is abnormal. It should be noted that the comparison between the first message data and the response message may also be performed manually by a worker at the network distribution master station side, so as to determine that the communication state of the encrypted communication device is normal.
The communication state is judged by setting the self-loop function for the encryption communication device, the technical problem that the encryption communication device which is arranged at a position difficult to be connected is disassembled to be detected when the encryption communication device arrives at the site in the prior art is solved, the communication state of the encryption communication device can be automatically detected, the technical effect that the encryption communication device is not required to be disassembled to be detected on the site is realized, and the working efficiency of operation and maintenance personnel is effectively improved.
