As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The present invention will be described in detail with reference to specific examples.
Example 1
Referring to fig. 1 and fig. 2, the present embodiment provides a bus transmission quality evaluation method, which can be applied to a medical service message interaction bus and the like, where the message interaction bus may be provided with a plurality of medical service nodes, for example, the nodes may include, but are not limited to, different medical platforms, third party platforms, medical device terminals and the like. Each node is connected to the bus via its bus interface, and performs communication and the like between the nodes via the bus. In this embodiment, the message interaction bus may adopt a communication bus such as a 659 bus and a CAN bus. As shown in fig. 2, the bus transmission quality evaluation method will be described in detail below.
And S100, monitoring the message interaction among the medical service nodes in real time to obtain basic indexes and dynamic indexes of the bus.
In step S100, the message interaction between the nodes is monitored in real time, so that the data transmission quality of the bus can be evaluated according to the corresponding indexes. Exemplarily, the bus can be connected through a corresponding collection interface, and the bus is also connected to each node, so as to collect the basic index of the bus and the message interaction state information of each node, and the like.
Step S200, calculating a quality evaluation index of the bus transmission message in a preset time period according to the basic index and the dynamic index and a preset rule, so as to evaluate the transmission quality of the bus.
In the step S200, the dynamic index is mainly related to time, and may specifically refer to a related parameter acquired within a certain time period. The quality evaluation index in the preset time period is calculated through the preset rule, so that the transmission quality in the time period can be reasonably evaluated and the like.
Specifically, as shown in fig. 3, the step S200 may include the following main steps:
and step S210, calculating the occurrence probability of the message according to the acquired basic indexes.
Exemplarily, the basic index mainly includes the number of bus open interfaces, the total concurrent capacity and the total message number of each bus open interface, and the like.
In view of that a bus may not use all the buses of the number of paths for data or message interaction between nodes, in this embodiment, the number of bus open interfaces refers to the number of buses used for message interaction between nodes, and may also be understood as the number of channels used for data transmission between nodes. For example, if 659 bus is adopted, since the 659 bus is composed of two sets of bus pairs, i.e. 4 buses, if only 2 buses are available for message interaction between nodes, the number of open interfaces of the bus is 2.
In this embodiment, each bus has its own concurrency capacity, that is, the maximum number of messages allowed to be processed simultaneously, so the total concurrency capacity of the open interfaces of each bus is the sum of the open concurrent capacities of each bus. For example, in the 659 bus, if the concurrent capacities of the 2 open buses are 8 and 10, respectively, the total concurrent capacity is 18.
In this embodiment, the total number of messages mainly includes the sum of messages to be processed, messages being processed, and messages that have been processed. It is understood that the above static indicators can be acquired through an acquisition interface connected with the bus.
And step S220, calculating the bus load rate, the fault rate and the failure rate in the preset time period by using a corresponding preset formula according to the acquired dynamic index.
Exemplarily, the dynamic index mainly includes the number of concurrent messages, the number of message faults occurring, the number of message failures occurring, the number of processed messages, and the like in the preset time period. The calculation formulas of the bus load rate, the fault rate and the failure rate are respectively as follows:
the number of concurrent messages refers to the number of messages monitored by the bus in the preset time period, and mainly includes the number of messages being processed on the open bus. The load condition of the bus can be obtained in real time by calculating the load rate of the bus, and then whether the bus is overloaded or not can be judged.
The message fault number mainly refers to the number of faults occurring in the operation process of the bus in the preset time period. For a high concurrency state, because the bus continuously processes messages, the probability of faults is higher, and at the moment, the quality evaluation result can better accord with the actual situation by recording the message fault number, so that the obtained quality evaluation is more accurate and the like.
Further optionally, the message failure count may comprise two parts, namely, the initial failure count and the accidental failure count. If the preset time interval comprises the initial period of time for starting and operating the bus, the initial failure frequency can be counted, and the accidental failure frequency can be counted after the bus enters the normal operation state.
It is understood that the above message failure may be judged by the message sending status or the message receiving status fed back by each node. For example, if a packet loss occurs, the node on the receiving side cannot receive the message packet, and thus it can be determined that a failure has occurred.
In this embodiment, the failure rate may also be determined by the message sending state or the message receiving state fed back by each node. For example, if it is found that the message status flag fed back by the receiving node is incorrect, that is, the received data packet is incorrect or information loss occurs, it may be determined that a failure has occurred. Similarly, at this time, the result of the quality evaluation can better meet the actual situation by recording the message failure number, so that the obtained quality evaluation is more accurate.
Then, after the bus load rate, the failure rate, and the failure rate within the preset time period are obtained, step S230 is executed, that is, the quality assessment index is calculated.
And step S230, calculating a quality evaluation index in the preset time period according to the message occurrence probability, the bus load rate, the fault rate and the failure rate according to a preset quality evaluation algorithm.
In this embodiment, a weight value is assigned to the occurrence probability of the message, another weight value is assigned to the bus load rate, the fault rate, and the failure rate that are obtained in real time, and then the quality assessment index is calculated by using a preset quality assessment algorithm as follows. Specifically, the preset quality evaluation algorithm is as follows:
the quality assessment index is the first preset weight and the probability of occurrence of the message plus the second preset weight (the bus load rate + the failure rate)
It is understood that the first preset weight and the second preset weight can be adjusted according to the specific bus operating environment, and the like. Preferably, the first predetermined weight ranges from 0.2 to 0.3, and the second predetermined weight ranges from 0.7 to 0.8.
After the quality evaluation index is obtained, whether the quality evaluation index tends to 100% or not can be judged, and if the quality evaluation index tends to 1, the transmission quality is good. Optionally, taking 0.98 as a demarcation point, if the demarcation point is higher than or equal to 0.98, judging that the transmission quality is better or acceptable; on the contrary, if the value is lower than 0.98, it indicates that the transmission quality is not good, and the bus may be optimized or adjusted accordingly, so as to improve the reliability of processing messages.
Further, as shown in fig. 4, the bus transmission quality evaluation method may further include a step S300 of displaying the obtained quality evaluation index in real time.
Exemplarily, the obtained quality evaluation index, the evaluation result and the like can be displayed in real time, so that a user can quickly and intuitively know the real-time operation condition of the bus, the quality of data transmission and the like, and further can remind overload, fault number overrun and the like.
According to the technical scheme of the embodiment, the relevant indexes of each service node and each bus during message transmission are monitored in real time, the quality evaluation indexes and the like are calculated by utilizing the indexes and relevant algorithms, the real-time evaluation of the transmission quality of the buses can be visually and effectively realized, the bus reliability can be further improved, the optimization reference can be further realized, in addition, an effective quality evaluation scheme is provided for the existing medical service system industry, and the defects in the prior art are made up.
