Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application discloses a module address allocation method, which improves the supervision efficiency of tourism behaviors.
Referring to fig. 1, a flowchart of a module address assignment method disclosed in an embodiment of the present application is shown in fig. 1, and includes:
s101: acquiring physical addresses of all online modules, and distributing continuous logical addresses for all online modules according to the physical addresses;
the embodiment is applied to a modular device comprising a plurality of modules, and the execution main body can be a processor of the modular device. The physical addresses of all online modules are first obtained before assigning logical addresses to the modules. In specific implementation, the physical address of each module may be determined according to a physical location where each module is specifically inserted, or may be set by manually dialing, or may be automatically determined by other methods, which is not specifically limited in this embodiment.
After the physical address of each module is determined, continuous physical addresses are allocated to each module according to the physical address. The present embodiment does not limit the specific allocation manner, and may randomly provide the consecutive addresses for each module; the order of the logical addresses of the modules can also be set according to the size order of the physical addresses of the modules, namely, the physical addresses of all online modules are sorted from small to large, and continuous logical addresses are distributed from small to large according to the sorting result; of course, the logical address may also be determined according to the weighted value of the physical address and the working state of the module, which will be described in detail in the next embodiment.
After the logic address is allocated to each module, the processor detects the working state of each module in real time, and if the module fault is detected to be offline, the process goes to S102. The specific detection method is not limited here, and the detection information may be sent to each module at preset intervals, or each module may send heartbeat information to the processor at preset intervals. Meanwhile, each module detects the previous logical address of the module in real time, and when the previous logical address is detected to be empty, S103 is entered.
S102: when an offline module is detected, setting the logic address of the offline module to be null;
in a specific implementation, when a module is failed or repaired during operation, the module is an offline module. When an offline module is detected, the processor sets the logical address of the offline module to null.
S103: when the online module detects that the target logic address is empty, the logic address of the online module is reduced by one; wherein the difference between the logical address of the online module and the target logical address is one
In specific implementation, each module detects the previous logical address of the module in real time, and when the previous logical address is detected to be empty, the logical address of each module is reduced by one. The subsequent module detects that the previous logical address is empty, and reduces the logical address by one. Therefore, when the physical addresses of the modules are discontinuous, the logical addresses can be ensured to be continuous through the combined sequencing of the logical addresses.
For example, the whole modular device has four modules, and the physical addresses are: 1. 2, (null), 4, 5, the processor allocates consecutive logical addresses to the four modules as: 1. 2, (null), 3, 4. When the module with the physical address of 4 (logical address of 3) fails and is offline, the processor sets the logical address of the processor to be null, and the logical addresses of the four modules are respectively: 1. 2, (empty), (null), 4. When a module with a physical address of 5 (logical address of 4) detects that a module with a logical address of 3 does not exist, the logical address of the module is reduced by one, and the logical addresses of the four modules are respectively as follows: 1. 2, (null), (empty), 3, ensuring the continuity of the logical addresses of the modules.
In the module address allocation method provided by the embodiment of the application, each module detects the previous logical address of its module, and when the previous logical address is detected to be empty, the previous logical address is reduced by one, and when the subsequent module detects that the previous logical address is empty, the logical address of its module is reduced by one, so that the module addresses are ensured to be continuous. When in maintenance, the module information of continuous addresses can be obtained, and the maintenance efficiency is improved.
The following describes in detail a method for allocating a logical address provided in this embodiment, specifically:
referring to fig. 2, a flowchart of another module address assignment method provided in the embodiment of the present application is shown in fig. 2, and includes:
s201: calculating a weighted value of each online module according to the physical address and the working state of each online module;
in this embodiment, the logical address is determined according to the weighted value of the module physical address and the operating state. Specifically, the weighted value of each online module can be calculated according to a weighted value calculation formula; wherein, the weighted value calculation formula is:
Y＝A2×N+A1；
wherein Y isThe weighting value, A2Is a formula value corresponding to the working state of the online module, A1And N is the maximum value of the physical addresses of all the online modules.
In specific implementation, the physical address and the working state are combined with each other by calculating the Y value, so that the module with the highest working state priority obtains the smallest logical address, and when the working states are consistent, the module with the smallest physical address has the smallest logical address. Namely, the formula value of the working state is positively correlated with the priority of the working state.
The embodiment does not specifically limit the specific working state and the formula value thereof, and those skilled in the art can flexibly set the working state and the formula value according to the actual situation. For example, the operating state priority from high to low may include an inverted state, a bypass state, a no output state, and the like. The formula value for the inverter state may be set to 3, the formula value for the bypass state to 2, and the formula value for no output to 1.
S202: and sorting the weighted values of all the online modules from small to large, and distributing continuous logic addresses from small to large according to a sorting result.
In specific implementation, the order of the logical addresses of the modules is set according to the magnitude order of the weighted values of the modules, and continuous logical addresses are distributed to the modules.

Step 1: in the memory, a storage space [ D ] is defined1、D2…Dm]And initialized to 0;
step 2: each module calculates the weighted value Y of each module by adopting the weighting mode provided by the previous embodiment;
and step 3: the weighted value is subjected to information sharing interaction of all modules in a communication mode to obtain weighted information Y of all modules1、Y2…Ym]；
And 4, step 4: each module judges the relation between the Y value of the module and the Y values of other modules, when the Y value of the module is the maximum value in the system, the logic address of the module is set to be 1, namely D is 1, the module Y is set to be zero, and the zero-set Y value is continuously subjected to information sharing;
and 5: all online modules continuously judge the relation between the Y value of the module and the Y values of other modules, when the Y value of the module is the maximum value in the system, the logic address of the module is set to be 2, namely D is 2, the module Y is also set to be zero, and the zero-set Y value is continuously subjected to information sharing;
step 6: repeating the steps until all the Y values of all the modules are 0 and all the D values are not 0, and sequentially obtaining the addresses D of all the modules;
and 7: when the address D of other modules is not received for a period of time, setting the address of the module which does not receive the address as 0;
and 8: all the online modules detect and identify whether the previous address is vacant (the modules with addresses of 0 and 1 do not perform the operation), and if the previous address is vacant, the logical address of the module is subtracted by 1, and the steps are performed in sequence.
