To facilitate understanding of the network system in this embodiment, please refer to fig. 5, and fig. 5 is a diagram illustrating a network topology of the network system related to the bandwidth partitioning method according to the present invention.

Reference numeral 4 denotes that the monitor can communicate with the slave device in the network system, and the monitor can communicate with the master even if the monitor is not directly linked with the slave.
On the basis of the network system structure, the bandwidth division method comprises the following steps:
step S10, determining the bandwidth ratio corresponding to each type of non-real-time service data, and determining the total bandwidth of the non-real-time service data in the network system;
the bandwidth ratios corresponding to various types of non-real-time service data are obtained, which can be determined by the ratio of the data volume of various non-real-time service data to all non-real-time service data, or preset bandwidth ratios can be performed according to the importance degrees of different types of non-real-time service data in data transmission, that is, the preset bandwidth ratios corresponding to various types of non-real-time service data can be determined according to the experience of technicians, and the criteria of the importance degrees can be as follows: disallowing loss of data > allow loss of a small portion of data > allow loss of a large portion of data > allow loss of all data.
For example, in one specific example:
the SDO service of the Ethernet Over Ethernet CAT belongs to standard service defined by a protocol, generally generated by main station equipment service, belongs to self-defined producer consumer service generally generated by a monitor, and belongs to parameter acquisition service generally generated by the monitor based on self-defined function code read-write of the Ethernet Over Ethernet CAT channel
For the protocol definition standard service data, the producer consumer service data, the parameter acquisition service and other consumption data, the corresponding bandwidth ratios are respectively 50%, 25% and 25% according to the data volume or importance degree of the three different non-real-time service data. It should be understood that the present invention is only exemplary, and is not limited to the bandwidth ratios corresponding to various types of non-real-time service data.
In an embodiment, the step of determining the bandwidth ratio corresponding to each of the various types of non-real-time service data in step S10 includes:
step a, acquiring target data volume and total non-real-time service data volume of various current non-real-time service data;
and b, determining the bandwidth ratio corresponding to each type of non-real-time service data according to each target data volume and the total amount of the non-real-time service data.
In this embodiment, the bandwidth ratio corresponding to each type of non-real-time service data may be determined by obtaining a target data volume and a total non-real-time service data volume of each type of non-real-time service data, and calculating a ratio of the target data volume of each type of non-real-time service data to the total non-real-time service data volume, specifically, dividing the target data volume of each type of non-real-time service data at the same time by the total non-real-time service data volume at the same time to obtain each ratio, where the ratio is the bandwidth ratio corresponding to each type of non-real-time service data.
By the embodiment, different target bandwidths can be allocated to different types of non-real-time service data in real time based on the real-time data volume of the non-real-time service data, the actual requirements of various data transmission at the same moment can be met, and the loss of the service data is prevented.
In another embodiment, the step of determining the bandwidth ratio corresponding to each of the various types of non-real-time service data in step S10 further includes:
step c, acquiring historical average data volume and historical average total amount of various non-real-time service data;
and d, determining the bandwidth ratio corresponding to each type of non-real-time service data according to the historical average data volume and the historical average total amount of the non-real-time service data.
In this embodiment, specifically, the historical average data size of each type of non-real-time service data within the preset time period is an average value obtained by dividing the total data transmission amount of each type of non-real-time service data within the preset time period by the preset time period, and the historical average total amount of non-real-time service data within the preset time period, that is, an average value obtained by dividing the total data transmission amount of all non-real-time service data by the preset time period, is obtained. The preset time period can be set according to actual needs, such as one week, one month, and the like.
And dividing the historical average data quantity by the historical average total quantity of the non-real-time service data to obtain each ratio, thereby determining the bandwidth ratio corresponding to each type of non-real-time service data.
By the embodiment, the transmission demand of different types of non-real-time service data in past history can be reflected to a great extent, the transmission demand of the different types of non-real-time service data can be further predicted, different bandwidth ratios are determined by taking each historical average data amount as a reference, and data transmission is carried out on the subsequent various types of non-real-time service data according to corresponding target bandwidths, so that stable transmission of various types of non-real-time service data can be ensured, and the various types of non-real-time service data can be responded by the slave station equipment timely and efficiently.
In an embodiment, the step of determining the total bandwidth of the non-real-time service data in the network system in step S10 includes:
step S11, acquiring a communication cycle between a monitor in the network system and a master station device in the network system and a cycle allowance of non-real-time data;
and step S12, calculating the total bandwidth of the non-real-time service data in the network system according to the communication cycle and the cycle allowance.
The element (parameter) for calculating the total bandwidth of the non-real-time service data is obtained based on the communication interaction between the monitor and the master station device, or the element (parameter) for calculating the total bandwidth of the non-real-time service data may be directly reading the total bandwidth NRT _ bw already calculated by the master station device or the control device in the network system itself, where the element for calculating the total bandwidth may be a communication period T _ c, a single-period non-real-time data allowable transmission size N _ b (a period allowable amount of the non-real-time data), and after multiplying the communication period and the period allowable amount or multiplying the communication period and the period allowable amount with a correction value, the total bandwidth per unit time (second) is calculated, and it can be seen that the non-real-time data bandwidth NRT _ bw is proportional to the communication period T _ c and the single-period non-real-time data size N _ b. More specifically: the total bandwidth factor includes the communication period, the non-real-time data size of each node, the total number of nodes in the network, the real-time data bandwidth occupation ratio allocated by the user, and the mode of calculating the total bandwidth may also be: the method comprises the steps of firstly obtaining the total bandwidth of a network system bus, obtaining the real-time data bandwidth according to the real-time data bandwidth occupation ratio distributed by a user, and subtracting the real-time data bandwidth from the total bandwidth to obtain the total bandwidth.
By the embodiment, the total bandwidth of all the non-real-time service data in the network system can be conveniently calculated through simple parameters.
Step S20, determining target bandwidth of each type of non-real-time service data according to the total bandwidth and each bandwidth ratio, wherein the target bandwidth is used for limiting data transmission quantity of each type of non-real-time service data in unit time.
In one embodiment, the step S20 includes:
and multiplying the total bandwidth by each product obtained by each bandwidth ratio, and taking each product as the target bandwidth of each type of the non-real-time service data.
The target bandwidth of the non-real-time service is obtained by multiplying the total bandwidth of the non-real-time service data by the bandwidth ratio of the non-real-time service data, and then the target bandwidth of each kind of non-real-time service data can be obtained, for example, the total bandwidth of the non-real-time service data is 100Mbps, wherein the bandwidth ratio of the protocol definition standard service in the non-real-time service data is 50%, and correspondingly, the target bandwidth of the protocol definition standard service is 50Mbps, that is, the data transmission of all the protocol definition standard services needs to be limited within 50Mbps, and no more bandwidth can be occupied.
The invention mainly divides the total bandwidth of the bus occupied by the non-real-time data, particularly allocates different target bandwidths to various non-real-time service data through the bandwidth occupation ratios corresponding to various non-real-time service data, namely the ratio of the bandwidths required to be occupied by the different non-real-time service data in unit time, and the total bandwidth of the bus occupied by all the non-real-time data obtained through calculation, limits the various non-real-time service data to carry out data transmission only in the allowed bandwidth, and further does not enable the plurality of different non-real-time service data to simultaneously occupy the same bandwidth, thereby enabling the distribution of the non-real-time service data to be more scientific and reasonable, avoiding the loss of the non-real-time service data and accelerating the response efficiency of the slave station equipment to the non-real-time service data sent by the master station equipment and the monitor.
Referring to fig. 4, fig. 4 is a flowchart illustrating a bandwidth division method according to a second embodiment of the present invention; further, a second embodiment of the bandwidth dividing method according to the present invention is proposed based on the first embodiment of the bandwidth dividing method according to the present invention, and in this embodiment, after step S20, the method further includes:
step S30, acquiring unit data volume to be transmitted of the current non-real-time service data to be transmitted;
step S40, judging whether the unit data volume to be transmitted is larger than the target bandwidth of the current non-real-time service data to be transmitted;
and S50, if the unit data volume to be transmitted is larger than the target bandwidth of the current non-real-time service data to be transmitted, outputting prompt information of data volume overrun.
In this embodiment, the currently-to-be-transmitted non-real-time service data may be a part of the non-real-time service data to be transmitted, which is selected by the user on the monitor or the host and monitor integrated machine. The unit data volume to be transmitted is the allowable data volume transmitted per second, the bandwidth to be occupied by the current non-real-time service data to be transmitted can be determined through the unit data volume to be transmitted, the size of the unit data volume to be transmitted and the target bandwidth of the current non-real-time service data to be transmitted is further judged, if the unit data volume to be transmitted is judged to be larger than the target bandwidth of the current non-real-time service data to be transmitted, a prompt message that the data volume of the non-real-time service data selected by a user is over-limited needs to be reminded, and the prompting mode is not limited to pop-up windows, voice alarms, vibration and the like.
In one specific example: after the monitor divides the target bandwidth of various non-real-time data, the monitor limits the reasonable use of non-real-time services by users in the reverse direction, for example, when continuous waveform acquisition (producer consumer service) is used as the current non-real-time service data to be transmitted, the available target bandwidth is 1/4 × nrt _bw, then the producer data generated by the monitored node number in the same network cannot exceed 1/4 × nrt _bw, that is, the unit data volume to be transmitted cannot exceed 1/4 × nrt u bw, otherwise, other service data are influenced. The monitor can give prompt and limit when the data generated by the service selected by the user exceeds the corresponding target bandwidth, so that the reasonable distribution and use of the non-real-time data and the service under different scenes are achieved.
In one embodiment, the network system further comprises a slave device; the bandwidth division method further comprises the following steps:
acquiring service response time of each type of non-real-time service data, and determining response priority of each type of non-real-time service data according to each service response time, wherein the service response time is inversely proportional to the response priority;
and the slave station device is used for responding to various types of non-real-time service data sent by the master station device or the monitor based on the response priority.
In this embodiment, each type of non-real-time service data has the required service response time T _ Rsp, that is, the master station device or the monitor sends the non-real-time service data and the slave station device needs to respond within the service response time, otherwise, the following data transmission will be affected, so that priorities are set for each type of non-real-time service data based on the length of the service response time, the higher the priority is, the shorter the service response time is, and the slave station device sequentially responds according to the priorities within the target bandwidth limit corresponding to each type of non-real-time service data according to the priorities of different types of non-real-time service data.
For example, the priority assignment is: the highest priority (protocol definition standard service), the medium priority (producer consumer service), and the lowest priority (parameter acquisition service and other consumption), which are used in the slave station device, when the slave station device needs to reply to the non-real-time service data with different priorities at the same time, the non-real-time service data with high priority is replied preferentially.
By the embodiment, the non-real-time service data with high requirement on service response time can be responded quickly and efficiently, and the influence of various data transmission obstacles on the next data transmission caused by the long response time of the slave station equipment on some non-real-time service data with high requirement on response time is avoided.
For further understanding of the above embodiments of the present invention, reference may be made to fig. 6, where fig. 6 is a schematic diagram of an overall application flow of the bandwidth division method of the present invention, and the overall flow in an actual application scenario of the present invention may be:
step 1, a monitor acquires and calculates loan elements and calculates the total bandwidth of non-real-time data;
and 3, distributing the specification of the corresponding service according to the divided target bandwidth of the non-real-time data, and giving a prompt when the service selected by the user exceeds the data bandwidth.
