In addition, the invention analyzes and prejudges the past fault record information, endows less time-consuming proportion to the network segments which frequently have communication faults, and avoids the network segments which easily have faults in certain specific time periods in advance through prejudgment, thereby greatly improving the communication quality.
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions in the embodiments of the present invention are further described in detail by the following embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows:
fig. 1 shows a schematic flow chart of a network segment switching method of a monitoring system according to an embodiment of the present invention. It should be noted that the network segment switching method of the present embodiment can be applied to various types of hardware devices; the hardware device may be a controller, such as an arm (advanced RISC machines) controller, an fpga (field Programmable gate array) controller, a soc (system on chip) controller, a dsp (digital Signal processing) controller, or an mcu (micro controller unit) controller, etc.; the hardware equipment can also be a Personal computer such as a desktop computer, a notebook computer, a tablet computer, a smart phone, a smart television, a Personal Digital Assistant (PDA for short) and the like; the hardware device may also be a server, and the server may be arranged on one or more entity servers according to various factors such as functions, loads, and the like, or may be formed by a distributed or centralized server cluster, which is not limited in this embodiment.
In this embodiment, the monitoring system communicates through a first network segment and a second network segment, and the first network segment and the second network segment alternately operate. The network segment switching method specifically comprises the following steps.
In step S11, it is detected whether the communication between the first network segment and the second network segment is abnormal.
Optionally, the detecting whether the communication between the first network segment and the second network segment is abnormal includes detecting whether network delay or communication interruption occurs in the communication between the first network segment and the second network segment. That is, if any one of network delay and communication interruption occurs in the communication of the network segment, it is considered that the communication is abnormal.
In step S12, if it is detected that the communication of the first network segment or the second network segment is abnormal, the data request is retransmitted after the network segment with abnormal communication is switched to the network segment with normal communication, and the first network segment and the second network segment are changed from the two network segments to be operated alternately to be operated by only one of the network segments.
Specifically, in order to balance the load during the normal operation of the monitoring system, the monitoring system may communicate with 2 network segments (e.g., network segment a and network segment B) at the same time, and the 2 network segments are performed alternately. If abnormal conditions such as network delay or communication interruption occur in one network segment in the working process, the network segment can be immediately switched to another network segment to retransmit a data request, and switching can be performed without waiting for the communication state interruption of the current network segment or the failure of ping of a certain IP in a ping local area network for multiple times, so that the communication network segment can be switched quickly, and uploading of key data and issuing of key operation instructions are ensured.
For example, as shown in fig. 2, the monitoring system utilizes a network segment a and a network segment B to perform data transmission, and each network segment is provided with devices such as a router, a switch, and a PC. And the network segment A and the network segment B alternately carry out data transmission, namely the network segment B is idle when the network segment A works, and the network segment A is idle when the network segment B works. If the network communication of the network segment A is interrupted, all the communication is transmitted through the network segment B. Therefore, the working mode of the network segment is changed from the original alternative working of the network segment A and the network segment B to the working of only the network segment B.
In step S13, if it is not detected that the communication in the first network segment or the second network segment is abnormal, the process returns to step S11.
In step S14, a network fault diagnosis is performed on the network segment with the communication abnormality, and it is determined whether the network segment is abnormal.
If the result of the diagnosis is abnormal in step S15, the process returns to step S12 to continue the operation in only one segment.
In step S16, if the diagnosis result is restoration, the first network segment and the second network segment are restored to operate alternately.
Generally speaking, network fault diagnosis can be automatically carried out after an A network segment is abnormal; if the diagnosis result is normal, continuing to return to the normal communication of the network segment A; if the diagnosis result is not failed, only the network segment B is continuously kept to carry out communication. And periodically (for example, every 5 minutes or 10 minutes) carrying out network fault diagnosis again until the network segment A is diagnosed as normal, and recovering the normal communication of the network segment A.
In an optional implementation manner of this embodiment, the network segment switching method further includes the steps shown in fig. 3.
In step S31, recording and storing the communication abnormality information of the first network segment and the second network segment; the communication abnormal information at least comprises timestamp information, frequency information, fault diagnosis time-consuming information or recovery communication time-consuming information of abnormal occurrence.
In step S32, the communication stability of the first network segment and the second network segment is analyzed according to the communication abnormality information.
Specifically, the communication stability of the network segment and the frequency of occurrence of the abnormality are in a reverse change relationship, and the time consumed for fault diagnosis and the time consumed for communication recovery are also in a reverse change relationship. According to the data such as the frequency of abnormal communication, the time consumed by failure, the time consumed by communication recovery and the like of a certain network segment, a score data is given to the network segment after comprehensive consideration, and the higher the score is, the stronger the communication stability is.
In step S33, the time ratio of the first network segment and the second network segment working alternately is adjusted according to the communication stability of the first network segment and the second network segment.
Specifically, the time ratio of the two network segments working alternately can be adjusted according to the respective stability of the two network segments. For example, the time ratio of the original alternate working of the network segment a and the network segment B is 5:5, and the communication stability analysis is carried out, and the stability of the network segment a is far higher than that of the network segment B, the time ratio of the alternate working can be inclined towards the network segment a, for example, the ratio is set to be 6:4 or even 7:3, and the like, so that most of the time of the monitoring system can be ensured to carry out data transmission through the network segment with higher stability, and the stability of the whole network transmission is improved.
In an optional implementation manner of this embodiment, the network segment switching method further includes the steps shown in fig. 4.
In step S41, recording and storing the communication abnormality information of the first network segment and the second network segment; the communication abnormal information at least comprises timestamp information, frequency information, fault diagnosis time-consuming information or recovery communication time-consuming information of abnormal occurrence.
In step S42, a failure pre-determination is performed on the communication abnormality of the first network segment and the second network segment according to the communication abnormality information.
Specifically, the network segment can be subjected to fault prejudgment according to timestamp information, frequency information, fault diagnosis time-consuming information, communication recovery time-consuming information and the like of the network segment with abnormality. For example, the frequency of the network segment a having an abnormality near a certain timestamp is large, and the frequency of the occurrence is close to once per week, so that the probability of the network segment a having an abnormality near the timestamp after one week can be predicted to be very high; for another example, the number of times that the network segment a becomes abnormal near a certain timestamp is large, the frequency of occurrence is close to once per week, and each time the communication is returned, it usually takes about 5 minutes, so that it can be predicted that the communication is returned about 5 minutes when the network segment a becomes abnormal next time.
In step S43, the frequency band switching and the network fault diagnosis are performed in advance according to the prediction result.
For example, if it is predicted that the probability that the network segment a is abnormal at a timestamp after a week is very high, the network segment B may be used to transmit data instead of the network segment a according to the prediction. For another example, if it is predicted that it takes about 5 minutes to recover the communication when the next anomaly occurs in segment a, it may be set to avoid using segment a and instead use segment B to transmit data within 5 minutes before and after the predicted timestamp of the next anomaly occurrence in segment a. Therefore, network segment switching can be performed in advance through prejudgment, and network segment switching efficiency is further improved.
In an optional implementation manner of this embodiment, the monitoring system includes a third network segment; the network segment switching method also comprises the steps shown in figure 5.
In step S51, it is detected whether the communication between the first network segment and the second network segment is abnormal.
In step S52, if it is detected that the communications in the first network segment and the second network segment are both abnormal, the current network segment is switched to the third network segment.
Otherwise, the third network segment is kept in an idle state in step S52.
That is, in the process of data transmission, the monitoring system is provided with a third network segment as an idle network segment in addition to the first network segment and the second network segment. The third network segment is in an idle state at ordinary times, and the first network segment and/or the second network segment are responsible for data transmission. And under the extreme condition that the first network segment and the second network segment both have faults, the third network segment is not in an idle state any more, but is used as a standby network segment in an emergency state to be responsible for the transmission work of all data, so that the risk resistance of the network is greatly enhanced.
