However, when the communication channel between the downstream modules behind the working module is abnormal, after the upstream modules interact with each other, it is determined that the working module works normally, the working module and the standby module are not switched, the downstream modules lack the ability to receive the output data of the working module, and the failure occurrence point cannot be accurately judged.

Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings. It is to be understood that the following specific examples are illustrative of the invention only and are not to be construed as limiting the invention. In addition, it should be noted that, in the case of no conflict, the embodiments and features in the embodiments in the present application may be combined with each other; for convenience of description, only portions related to the invention are shown in the drawings.
As shown in fig. 1, the present embodiment discloses a hot standby redundancy method, including two mutually redundant upstream modules and a downstream module, where the method includes:
s1: at least two upstream modules interact to determine a working module and a standby module;
s2: the working module sends a first processing result of the data processing to the downstream module and the standby module;
the standby module sends a second processing result of the data processing and the first processing result sent by the working module to a downstream module;
s3: and the downstream module selects the optimal data to process according to the received data.
In one embodiment, the specific method for determining the working module and the standby module in S1 is as follows:
s101: the first upstream module diagnoses the working state of the first upstream module and sends a diagnosis result to the second upstream module;
s102: the second upstream module diagnoses the working state of the second upstream module and sends a diagnosis result to the first upstream module;
s103: and the first upstream module and the second upstream module compare the diagnosis result of the working state of the first upstream module with the diagnosis result of the working state of the second upstream module according to the diagnosis result of the working state of the first upstream module and the diagnosis result of the working state of the second upstream module, and select the upstream module with the best working state as the working module.
The upstream module diagnoses the upstream module, and evaluates the fault grade of the upstream module according to the fault type of the upstream module on the system influence surface, wherein the fault grade is lower when the influence surface is smaller. And after the self fault level is obtained, the fault level information is forwarded to another upstream module, and after mutual comparison, the upstream module with the lower fault level is selected as a working module. And when the upstream modules have no faults, the upstream modules which are powered on preferentially serve as working modules according to the power-on sequence.
In another embodiment, the specific method for determining the working module and the standby module in S1 is as follows:
s111: the first upstream module processes the received data to obtain a first data processing result and sends the first data processing result to the second upstream module;
s112: the second upstream module processes the received data to obtain a second data processing result and sends the second data processing result to the first upstream module;
s113: and the first upstream module and the second upstream module compare the processing result of the data with the processing result of the data by other upstream modules according to the processing result of the data, and select the upstream module with the optimal processing result as a working module.
The upstream module processes the data according to the received data and generates a quality code, the quality code comprises information such as unreasonable data and bad data, and parameters such as current, voltage and temperature of the upstream module, when the parameters are abnormal, the quality code can mark the corresponding parameters and reduce the quality code, and the integrity of the data with higher quality code is higher.
After the first upstream module processes the data, a first data processing result is generated, a quality code of the first data processing result is given, and a check code is attached to the quality code, and the first upstream module sends the first data processing result to the second upstream module. Similarly, the second upstream module generates a second data processing result, gives a quality code of the second data processing result, attaches a check code and sends the second data processing result to the first upstream module, and the first and second upstream modules respectively analyze the data processing result sent by the other side, compare the quality code information in the data processing result, determine the upstream module with higher data integrity as a working module, and use the other upstream modules as standby modules. And when the quality code results generated by the upstream modules are the same, the upstream module which is powered on preferentially serves as a working module according to the power-on sequence.
As shown in fig. 2, after the upstream module determines the working module 101 and the standby module 102, the working module 101 sends its own data processing result data packet 111 to the standby module 102 and the downstream module 201 at the same time, and after receiving the data packet 111, the standby module 102 sends its own data processing result data packet 113 to the downstream module 201. At this time, the downstream module receives 3 data packets in total, including the data packet 111 sent by the working module 101 directly to the downstream module 201, the data packet 112 sent by the standby module 102 to the downstream module 201, and the data packet 113 generated by the standby module 102, where the standby module 102 only forwards the data packet 111 of the working module, and the downstream module 201 receives the same two data packets 111 and 112 when the system has no fault.
Further, when the working module 101 and the standby module 102 send data to the outside, both tags the data, for example, the data packet 111 is tagged with the tag 131 of the working module, and when the standby module 102 sends its own data processing result data packet 113 and the forwarded data packet 112, the tag 132 of the standby module is also tagged. Therefore, as shown in fig. 3, the three packets received by the downstream module 201 are the packet 111 with the tag 131, the packet 112 with the tag 131 and the tag 132, and the packet 113 with the tag 132.
When the downstream module 201 selects data, it preferentially selects a data packet with a working module tag 131, and the specific method includes:
s301: the downstream module 201 selects according to the label on the received data, compares the data packet 111 with the working module label 131, and judges whether the data packet 111 with the working module label 131 is optimal or not, if so, executes S302, otherwise executes S303;
s302: selecting a data packet 111 only with a working module label 131;
s303: comparing the data packet 112 with the spare module tag 132 with the data packet 113, and judging whether the data packet 112 with the working module tag 131 is better than the data packet 113 without the working module tag 131, if so, executing S304, otherwise, executing S305;
s304: selecting the data packet 112 with the working module label 131 and the standby module label 132 for processing;
s305: the packet 113 with only the spare module label 132 is selected.
When the downstream module 201 selects according to the received data packet, the integrity of the data packet is checked through the check code of the data packet 111, and the quality code information in the data packet is analyzed, so as to determine the quality of the data packet by comparing the integrity of the data and the quality code information. The data packet with the working module tag 131 is preferably selected, so that the downstream module can refer to the result of data interaction between the upstream modules when performing data selection, and select more complete data processing. Taking the model in fig. 2 as an example, when a communication channel between the working module 101 and the downstream module 201 fails, a data packet with a tag 131 received by the downstream module includes a data packet 111 and a data packet 112, where the data packet 111 cannot be received by the downstream module 201 or the data packet 111 loses packets due to the channel failure, and the communication quality is reduced. At this time, the downstream module 201 may also obtain the data packet 112 of the working module 101 through the communication channel of the standby module 102, and ensure that the data packet 111 generated by the working module 101 can be smoothly sent to the downstream module after the upstream module determines the working module 101 with the optimal operation, and when the communication channel between the working module 101 and the downstream module 201 fails, the data packet 111 generated by the working module 101 may also be forwarded through the communication channel between the standby module 102 and the downstream module 201, so that the downstream module 201 can always receive the data packet generated by the optimal module determined between the upstream modules, and the security and reliability of the system are improved.
In another embodiment, the downstream module 201 sends feedback information to the upstream module based on the selected data packet. Taking fig. 2 and fig. 3 as an example, the downstream module 201 selects according to the received data packet, after parsing the data packet, preferentially selects the data packet 111 with the working module tag 131 and the data packet 112 for comparison, and parses the quality code in the data packet, since the data packet 111 with the working module tag 131 and the data packet 112 are data packets generated by modules with better operation state after interaction between the upstream modules, the quality of the data packet is generally better. Preferably, the downstream module 201 can be guaranteed to obtain better data. When the data obtained by the downstream module 201 is compared, the quality of the data packet 112 with the spare module tag 132 is better than that of the data packet 111 with only the working module tag 131, or the data packet 111 with only the working module tag 131 is not received, the downstream module selects the data packet 112 with the tag 131 and the tag 132 to process, and determines that a communication channel between the working module 101 and the downstream module 201 has a fault. At this time, a feedback signal including the fault information diagnosed by the downstream module 201 is transmitted to the upstream module through the communication channel between the downstream module 201 and the standby module 102.
If the data finally selected by the downstream module 201 is the data packet 113 with only the spare module tag 132, it is identified that the quality of the data packet 111 and the quality of the data packet 112 received by the downstream module 201 are not better than that of the data packet 113, the downstream module 201 may determine that the working module 101 has a fault, and feed back the fault information to the upstream module, and simultaneously trigger the working and spare switching between the upstream modules, and the upstream module performs the switching according to the feedback information sent by the downstream module 201. The result of selecting the data packet through the downstream module 201 is fed back to the upstream module, so that the fault point of the system can be quickly determined, the maintenance and the replacement are convenient, and the overall safety and the reliability of the system are improved.
In another embodiment of the present application as shown in fig. 5, after the working module 103 and the standby module 104 are selected by the upstream module, the working module 103 and the standby module 104 both send data packets obtained by processing data to the downstream module 202 and other upstream modules at the same time, when the working module 103 and the standby module 104 send the data packets to the outside, each label is marked, and the data packets are recorded according to the sequence of the labeling of the upstream modules. Taking fig. 6 as an example, further explaining this embodiment, the data packets sent by the upstream module to the downstream module 202 total 4 packets, and when the downstream module 202 selects a data packet, the data packet with the working module tag 133 and the tag 133 marked first according to the sequence is preferentially selected, that is, the data packet 114 and the data packet 115. The data packet 114 is directly sent to the downstream module 202 by the working module 103, and after the data packet 114 is sent to the standby module 104 by the working module 103, the standby module 102 marks the label 134 again and forwards the data packet to the downstream module 202. Similarly, when the data of the working module 103 is abnormal and both the data packet 114 and the data packet 115 are abnormal, the downstream module 202 selects the data packet with the spare module tag 134, and the data packet marked first is selected and analyzed again, wherein the data packet 116 is directly sent to the downstream module 202 for the spare module 104, and after the data packet 117 is sent to the working module 103 for the spare module 104, the working module 103 marks the tag 133 and forwards the data packet to the downstream module 202. When the working module 103 fails, the downstream module 202 may also obtain the data packet of the standby module 104 through the communication channel between the working module 103 and the standby module 104 and the downstream module 202. The downstream module 202 can be guaranteed to always pass through the optimal channel, the data packet of the optimal upstream module is obtained, and the safety and reliability of the system operation are guaranteed.
As shown in fig. 7, another embodiment of the present application includes three upstream modules, and after the three upstream modules interact with each other, an optimal module is determined as a working module, and the other two upstream modules are determined as standby modules. When the upstream module sends a data packet to the downstream module, the working module forwards the data packet to the downstream module through the two standby modules at the same time. The optimized upstream module can select the communication channel to perform optimal data transmission in the three channels, and the safety and reliability of the system are ensured. In addition, in an implementation mode, the three upstream modules mutually interact self fault information, sorting is carried out according to the fault information, a working module, a first standby module and a second standby module are screened out, the working module only forwards a data packet through the first standby module, the downstream modules receive 4 data packets in total, the working module data packet and the first standby module data packet forwarded by the first standby module and the second standby module data packet are included, the implementation mode ensures that the working module data are stably transmitted, meanwhile, the data interaction time among the upstream modules is reduced, and the transmission efficiency is improved.
Further, the system comprises a plurality of downstream modules, for example, two downstream modules work independently and respectively receive data sent by the upstream modules, after the standby module for work is determined by the three upstream modules, the upstream modules simultaneously send data packets to the two downstream modules, after the downstream modules receive the data packets, the data packets are processed independently, interaction is carried out according to data selection results and operation results of the downstream modules, and meanwhile, the working states of the downstream modules are interacted, so that the working and standby relation of the downstream modules is determined. The redundant downstream modules are arranged, and the two downstream modules respectively receive the data packet sent by the upstream module, so that the safety and the reliability of the system can be further guaranteed.
It should be noted that the upstream module and the downstream module are only approximately described from the perspective of data transmission and reception, and the method may be applied to each data transmission and reception link of the system, for example, between the data acquisition module and the controller module, the acquisition module serves as the upstream module, the controller module serves as the downstream module, the acquisition module performs processing according to the relevant information of the acquisition site, and transmits the processing result to the controller module. When the method is applied between the controller module and the output module, the controller module is used as an upstream module to send a specific operation instruction to the output module, and the output module is used as a downstream module for receiving data to select the data sent by the controller module.
