Detailed Description
The core of the invention is to provide a method for reporting address conflict of modules in parallel, which realizes the reporting of address conflict when the address conflict occurs to the modules in parallel.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
Referring to fig. 1, fig. 1 is a flowchart of an implementation of a method for reporting address conflicts in parallel connection of modules, where the method is applied to each module connected in parallel on a data transmission line, and a module address of each module is formed by a physical address and a conflict address, and the method includes the following steps:
step S101: the method comprises the steps of obtaining a module address of the self and monitoring a first time length of a data transmission line.
For each module connected in parallel on the data transmission line, after the power-on start, the module address of the module is acquired and the first time length of the data transmission line is monitored. The module address of each module is composed of a physical address and a conflict address, the physical address is an address used by each module in the prior art for data transmission on a data transmission line, and the conflict address is an address added to each module in the scheme of the application and forms the module address of the corresponding module together with the physical address. Therefore, the existence of address conflict between two modules described in this application means that the module addresses of the two modules are the same, and specifically, the physical addresses of the two modules are the same, and the conflicting addresses are also the same. It should be noted that, in general, the conflicting addresses of the modules are the same before modification, i.e., the initial settings of the conflicting addresses of the modules are generally the same.
The data transmission line can be a data bus usually, a specifically adopted data transmission protocol can also be set according to actual needs, each module is connected on the data transmission line in parallel, and data interaction can be carried out with the data transmission line based on the module address of the module.
The module monitors the data transmission line, which means that the module obtains the module address of each other module which is transmitting data through the data transmission line, and compares the obtained module address of each other module with the module address of the module. The first time length can be set and adjusted according to actual conditions, for example, according to the number of modules connected in parallel on the data transmission line, the type of the data transmission line, the data transmission rate and other factors, without affecting the implementation of the present invention.
After listening for the first duration, the operation of step S102 may be performed.
Step S102: and when the module address is determined to have address conflict within the first time length, modifying the conflict address in the module address according to a preset rule.
And aiming at any module, when the module determines that the address conflict exists in the module address of the module within the first time period, the module indicates that the module address of at least one other module connected in parallel on the data transmission line is the same as the module address of the module. Therefore, in the scheme, the module modifies the conflict address in the module address according to the preset rule. The preset rule may be set according to an actual situation, but it may be clear that, after being modified according to the preset rule, the module address of the module will change, and specifically, the conflicting address in the module address will change.
Of course, for any module, when the module does not determine that the address conflict exists in the module address within the first time period, it indicates that the module address of the module is normal, and the module can start to operate normally. When each module does not determine that the address conflict exists in the module address of the module in the first time length after the module is started, the module address of each module connected in parallel on the data transmission line is normal.
S103: and monitoring the second time length of the data transmission line, and judging whether the modified module address has address conflict.
After modifying the module address, the module continues to monitor the second time length of the data transmission line, and judges whether the modified module address has address conflict. The second duration may also be set and adjusted according to factors such as the data transmission rate of each module.
The operation of step S104 may be performed when it is determined that there is no address conflict for the modified module address within the second duration, and the operation of step S105 may be performed when it is determined that there is an address conflict for the modified module address.
Step S104: and sending data with preset frame number through the modified module address, and stopping sending the data per se after the data is sent.
And judging that the modified module address has no address conflict in the second time length, and indicating that the module addresses of other modules performing data interaction through the data transmission line in the second time length are different from the modified module address of the module. The module sends the data with the preset frame number through the modified module address, and stops sending the data after the data is sent.
It is convenient to understand that the description is made with a specific example in which the initial conflicting addresses of the respective modules are the same. For example, the module address of module a is configured to: conflict address one + physical address a, module address of module B is configured as: the module A is electrified and started, data interaction is carried out through a data transmission line, and if the module B is electrified and started and an address exception occurs, the module address is changed into: conflict address one + physical address a. At this time, after the first duration is monitored, the module B finds that its own module address has an address conflict, which in this embodiment is the module address conflict with the module a. The module B modifies the module address of the module B into: conflicting address two + physical address a. After the second time length is monitored continuously, the module addresses of the modules performing data interaction through the data transmission line in the second time length are determined to be different from the second conflict address plus the physical address A, at the moment, the module B transmits the data with the preset frame number through the second conflict address plus the physical address A, and the data transmission of the module B is stopped after the data transmission is completed.
Step S105: and continuously monitoring the data transmission line, when the modified module address is determined not to conflict any more, transmitting the data with the preset frame number through the modified module address, and stopping the data transmission of the module after the data transmission is finished.
And judging that the address conflict still exists in the modified module address in the second time length, and indicating that at least one of the module addresses of other modules performing data interaction through the data transmission line in the second time length is the same as the modified module address of the module. The module continues to monitor the data transmission line until it is determined that the modified module address is no longer in conflict, transmits the data of the preset frame number through the modified module address, and stops transmitting the data of the module after the data transmission is completed.
Still referring to a specific example, for example, the module address of module a is configured as: conflict address one + physical address a, module address of module B is configured as: conflict address one + physical address B, module address of module C is configured as: conflict address one + physical address C. After the module A is electrified and started, data interaction is carried out through a data transmission line, and if the module B and the module C are electrified and started in sequence after the assumption, and all the modules have abnormal addresses, the module addresses are changed into the following modules: conflict address one + physical address a. At this moment, after the modules B and C are powered on, the first time of the data transmission line is monitored, the address conflict of the module addresses of the modules B and C can be found in sequence, and the module addresses of the modules B and C are modified into the following modules according to the preset rule: conflicting address two + physical address a.
Then, for example, the module B monitors a second time period, determines that the module addresses of the modules performing data interaction through the data transmission line in the second time period are all different from the "conflict address two + physical address a", and at this time, the module B transmits data of a preset frame number through the module address "conflict address two + physical address a", and stops its own data transmission after the data transmission is completed. In the process of monitoring the second time length by the module C, if the module B may be transmitting data of a preset frame number, in the second time length, the module C may determine that address conflict still exists in the modified module address "conflict address two + physical address a", and therefore, the module C continues to monitor the data transmission line until it is determined that the modified module address no longer conflicts, transmits the data of the preset frame number through the "conflict address two + physical address a", and stops transmitting the data of its own after the data transmission is completed. When the module C monitors that the "conflict address two + physical address a" does not conflict any more, it indicates that the data of the module B has been sent.
In the foregoing embodiment, the module address conflicts of two and three modules are taken as an example for description, when there are more module address conflicts, each module that monitors the address conflicts sequentially transmits data with the preset frame number, and the upper system may determine the number of modules with address conflicts according to the total frame number of the received data with the preset frame number.
The method provided by the embodiment of the invention is applied to each module which is connected in parallel on a data transmission line, and the module address of each module consists of a physical address and a conflict address, and comprises the following steps: acquiring a module address of the self and monitoring a first time length of a data transmission line; when the module address is determined to have address conflict within the first time length, modifying conflict addresses in the module address according to a preset rule; monitoring a second time length of the data transmission line, and judging whether address conflict exists in the modified module address; if not, sending data with preset frame number through the modified module address, and stopping self data sending after the data sending is finished; if yes, the data transmission line is monitored continuously, when the fact that the modified module address does not conflict any more is determined, data of a preset frame number is sent through the modified module address, and data sending of the data transmission line is stopped after the data sending is completed.
In the scheme of the application, when any module monitors that the module address conflicts, the module address of the module is modified, specifically, the conflict address in the module address is modified. Therefore, if only two modules have module address conflicts, the modified addresses can not conflict any more because the modules monitoring the module address conflicts modify the module addresses. That is, after the module monitors the second duration of the data transmission line, it can be determined that the modified module address does not conflict any more, and the data with the preset frame number is sent through the modified module address, so that the upper system can know which module address conflicts. If there are three or more modules with module address conflicts, after the module monitoring the module address conflicts modifies the module address, the modified address may still conflict because other abnormal modules may be sending data of the preset number of frames. The module continues to monitor the data transmission line until the modified module address is determined to be no longer conflicted, the data with the preset frame number is sent through the modified module address, the data sending of the module is stopped after the data sending is completed, and the upper system can determine the conflicted module address and the number of conflicted modules. In summary, when address conflicts occur to the modules connected in parallel, the scheme of the application realizes the reporting of the address conflicts.
In one embodiment of the present invention, the data transmission line is a data bus on a modular uninterruptible power supply UPS.
The application field of a modular UPS (Uninterruptible Power Supply) is getting larger and larger due to its good availability and stability, which is a trend of future development, and therefore, in a specific implementation, the data transmission line may be a data bus on the modular UPS. When the data transmission line is a data bus on the modular UPS, after the applicant considers the data transmission rate of the data bus, the number of modules and the like, the first duration and the second duration are both set to be 3 seconds, and the duration of the 3 seconds is set to be a proper duration setting, so that the situation that whether address conflict exists or not cannot be accurately judged due to too short time, and the slow process of starting the modules due to too long time cannot be caused.
In one embodiment of the present invention, the module address is an address formed by 1-bit conflict address and 5-bit physical address bits, and the conflict address is the highest order bit of the module address.
Considering that the number of modules does not exceed 32 in general, the physical address among the module addresses may be set to 5 bits. The conflict address is also part of the module address, and the larger the space occupied by the conflict address, the more affected the data transfer of the module, so the conflict address can be set to 1 bit as the highest bit in the module address. The setting mode is favorable for reducing the occupied space of the module address in the data transmission process.
In the embodiment that the conflict address is set to 1 bit, the modifying the conflict address in the module address according to the preset rule in step S102 may specifically be: and according to a preset rule, modifying the conflict address from 0 to 1.
It should be noted that in this embodiment, the initial conflict addresses of the modules are all 0. For example, the initial normal module addresses of a module are 000101, 0 and 1 are binary machine languages, wherein 00101 is the physical address, and the highest 0 is the conflict address, which is usually called as a conflict bit because the conflict address in this embodiment is a bit. When the module modifies according to the preset rule, the module can modify the conflict bit from 0 to 1. Of course, in other embodiments, the initial conflict addresses of each module may also be set to 1, and accordingly, when the modification is performed according to the preset rule, the conflict bit may be modified from 1 to 0, which does not affect the implementation of the present invention.
In a specific embodiment of the present invention, the number of bits of the conflict address in the module address is greater than or equal to the number of bits of the physical address; accordingly, in this embodiment, the preset rule includes: conflicting addresses after modification by respective modules are different from each other.
In the foregoing embodiments, when the conflicting addresses need to be modified, the modification rules of the modules are the same, for example, when the modules B and C sequentially modify the conflicting addresses, the module addresses are: "conflicting Address one + physical Address A" is modified to: "conflicting address two + physical address a", which is also a common implementation. Since the conflict address is an address newly added to each module in the present application, if the conflict address is set to be too long, the space occupied by the conflict address is large, and the data transfer of the module is affected, the conflict address is usually set to be short, and the conflict address is the highest order of the module address in the foregoing embodiment. Because the conflict address is shorter and the number of modules is larger, when the conflict address is modified, the modules are generally modified in the same way. However, since the modification modes are the same, there may be a situation where multiple address conflict modules use the same address to report data, and to specifically locate which modules have address conflicts, further determination by the upper system is required, for example, which modules have not sent data for a long time may be observed to find out the modules with abnormal addresses.
In this embodiment of the present application, more bits are allocated to the conflicting addresses, specifically, the bits of the conflicting addresses in the module addresses are greater than or equal to the bits of the physical addresses, so that when the conflicting addresses are modified by each module, the modified conflicting addresses are different from each other. The specific modification modes of the modules can be preset and stored in preset rules.
In this embodiment, since the collision addresses of the modules after modification are different from each other, the modules with address collision use different module addresses when reporting data, so that the upper system can directly locate the module with an abnormal address according to the module address used by the module to modify the collision address when sending the data with the preset number of frames, thereby saving the locating time.
In a specific embodiment of the present invention, the data of the preset frame number sent by the modified module address is data carrying preset alarm information.
In the scheme of the application, the data with the preset frame number sent by the module with the modified conflict address can be any data, and the implementation of the invention is not influenced. Specifically, when the data with the preset frame number does not carry specific information, the modules monitoring the address conflict stop sending the data with the preset frame number after sending the data with the preset frame number, the upper system can count the modules without data interaction for a long time, and select the modules sending the data with the preset frame number from the modules, so that the fault of the module or the modules can be determined.
In this embodiment of the present application, the data with the preset frame number sent by the module with the modified conflict address is data carrying specific information, specifically data carrying preset alarm information. Therefore, the upper system can timely and accurately determine that the address conflict occurs in the module according to the alarm information in the data, and further, related prompt information can be sent to prompt related personnel to process in time. Therefore, the data in the implementation mode carries preset alarm information, and timely discovery and processing of address conflict faults are facilitated.
In one embodiment of the present invention, the preset number of frames is 10 frames. Considering that the preset frame number of data sent by the module with the modified conflicting address is preferably data carrying alarm information, and the alarm information may be generally represented by 10 frames of data, therefore, in this embodiment, the preset frame number is 10 frames, and of course, certain adjustment may be performed according to actual situations.
