Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a schematic diagram of parallel connection of modules in the prior art. As shown in fig. 1, a total of 7 modules are connected in parallel in the order from left to right, and the 7 modules are respectively a module A1, a module A2, a module A3, a module A4, a module A5, a module A6 and a module A7.
In this prior art, 5 dial switches of 1, 2, 3, 4, 5 are provided on each module, in each of which the dial up code represents a binary "1", the no dial (i.e. held in the lower position) represents a binary "0", and the 5 dial switches from left to right represent decimal 1, 2, 4, 8, 16, respectively, according to the binary principle. Therefore, by performing different dialing settings on different modules so that the addresses of the different modules are different, the actual addresses of the modules can be determined. For example, in the module A1, only the switch corresponding to 5 is pulled up, and the address of the module A1 is 01; in the module A2, only the switch corresponding to 4 is dialed up, and the address corresponding to the module A2 is 02; in the module A3, when the switches corresponding to 4 and 5 are dialed up, the address corresponding to the module A3 is 01+02=03; in the module A4, the switch corresponding to 3 is dialed up, and the value corresponding to the module A4 is 04; in the module A5, the corresponding switches of 3 and 5 are upwards dialed, and the corresponding value of the module A5 is 05; in the module 6, the corresponding switches of 3 and 4 are upwards dialed, and the corresponding value of the module A6 is 06; in the module A7, when the switches corresponding to 3, 4, and 5 are pushed up, the value corresponding to the module A7 is 07.
However, with the above-described approach, after the respective modules are installed on site, a person familiar with the operation is required to complete the confirmation of the module addresses. On the one hand, manual operation is needed, so that operation inconvenience is brought, and on the other hand, a certain technical requirement is needed for an installer, so that later maintenance is not facilitated.
Based on the method, the method can automatically identify the module address by utilizing the bar code information of each module when leaving the factory, is free from manual intervention, is simple to operate, and brings convenience for adding or reducing modules in the later period.
It can be understood that the bar code information carried by each module when leaving the factory is unique bar code information, namely the bar code information between every two modules is different.
Fig. 2 is a flowchart of a method for determining a module address, which is provided by the present application, and is applied to a communication network, where the communication network includes at least one module, and the modules are connected through a bus, where each module is provided with barcode information, and the barcode information in different modules is different. The method comprises the following steps:
201: and sending bar code information to the bus.
After each module is connected to the bus, the first step is that the bar code information of the module is sent to the bus, so that other modules except the module can acquire the bar code information of other modules from the bus.
In this embodiment, the bus may refer to a CAN bus, and each module may refer to a power module, that is, each power module is connected through the CAN bus and communicates through the CAN bus. CAN is an abbreviation for controller area network (Controller Area Network, CAN), which is one of the most widely used internationally used fieldbuses.
Further, in an embodiment, before performing the step of sending barcode information to the bus, the module address determination method further comprises the steps of:
301: setting the address of the module as a first preset value, and sending a bar code information request instruction to the bus.
The specific operation is as follows: after the module is powered on for communication, the address of the module is often initialized and set to a first preset value, for example, the address of the module is initialized to 1. Meanwhile, the module actively sends a bar code information request instruction to the bus, namely, requests to acquire bar code information sent by other modules except the module on the bus. And, if in the application of the power module, the transmission period of the barcode information request command may be set to 400ms.
302: if a bar code information request instruction of a non-self module on the bus is received, the step of sending bar code information to the bus is executed.
If the bar code information request instruction of the non-self module can be received from the bus, other modules besides the self module are described as being connected to the bus, and the other modules can determine the address of the self module as the other modules also need to know the bar code information of the self module, so that the self module needs to send the bar code information of the self module to the bus at the moment. And, if in the application of the power module, the transmission period of the barcode information of the module can be set to 400ms.
It is to be understood that in all embodiments of the application, other modules or other modules are typically referred to as modules other than the present module being connected to the bus. And this module refers to any one of all modules connected to the bus.
303: and if the bar code information request instruction of the non-self module on the bus is not received, delaying a second preset time length.
304: and stopping sending the bar code information request instruction to the bus at the moment when the second preset time period is over, and executing the step of sending the bar code information to the bus.
If the module does not receive the bar code information request instruction from other modules on the bus, delaying a second preset time length. And stopping sending the bar code information request instruction to the bus by the module at the moment when the second preset time period is over, and starting to send the bar code information of the module to the bus. For example, if the second preset duration is 3S, if the module does not receive the instruction of requesting the barcode information of other modules on the bus, after 3S, the module stops starting the instruction of requesting the barcode information and starts to send the barcode information of the module to the bus. Similarly, when the method provided by the application is applied to the power module, the period for transmitting the bar code information of the module can be set to 400ms.
In summary, after each module is successfully powered on and establishes communication, the module address of the module is initialized to a first preset value, and each module actively sends an instruction for requesting bar code information to the bus. If the bar code request instruction of the non-self module can be received, which means that at least two modules are connected to the bus, each module is required to send the bar code information of the module to the bus. If the bar code request command of the non-self module is not received, it indicates that only one module is likely to be connected to the bus, bar code information can be sent to the bus, or the bar code information can be sent to the bus without limitation, but in the embodiment of the application, after the second preset time is delayed, the bar code request command of the self module is stopped, but the bar code information of the self module is still sent, so that when a new module is accessed subsequently, the new module can directly acquire the bar code information of the self module from the bus, thereby being beneficial to improving the efficiency.
202: if the bar code information of the non-self module is not received, delaying the first preset time length.
203: and stopping sending bar code information to the bus at the moment when the first preset duration is over, and determining the address of the module as a first preset value.
After the bar code information request instruction is sent to the bus, if the bar code information of other modules is not received, it can be determined that only the module is connected to the bus, and then the bar code information sending to the bus can be stopped. And further, delaying the first preset time, stopping sending the bar code information to the bus at the moment when the first preset time is ended, and simultaneously, directly setting the address of the module to be a first preset value.
In combination with the above embodiments, the first preset value is taken as 1 as an example for explanation. After each module is powered on and communication is established, initializing the address of each module to be 1. And then, sending the bar code information of the module to the bus, and if the bar code information of other modules is not received, directly setting the address of the module to 1 after stopping sending the bar code information to the bus. It should be understood that, before sending the bar code information to the bus, if a bar code request instruction of other modules is received, the address of the module may be actively reset to 1, so as to ensure that the initial value of the module is 1.
204: if at least one piece of bar code information of the non-self module is received, the address of the self module is determined according to the received at least one piece of bar code information of the non-self module.
Assume that the present module receives barcode information of N non-present modules (other modules), where N is a natural number greater than 0. The N bar code information is firstly stored in a memory space corresponding to the module, so as to be used for determining the address of the module subsequently. Then, the address of the module can be determined by combining the N bar code information and the bar code information of the module.
Specifically, in one embodiment, the following method is adopted to determine the address of the present module through the N pieces of barcode information and the barcode information of the present module, as shown in fig. 4, and the method includes:
401: judging whether at least one bar code information corresponding to the bar code information is smaller than the bar code information corresponding to the bar code information of the module in each bar code information of the non-module.
402: if yes, traversing each piece of bar code information, and if the number corresponding to each piece of bar code information is smaller than the number corresponding to the bar code information of the module, adding a second preset value to the address of the module.
403: if not, keeping the address of the module unchanged.
In the module, the numbers corresponding to the stored bar code information of other modules and the numbers corresponding to the bar code information of the module are ordered, so that the K bar code information of which the numbers corresponding to the bar code information are smaller than the K bar code information of the numbers corresponding to the bar code information of the module in the N bar code information of the other modules can be determined, wherein K is a natural number which is smaller than or equal to N and is larger than or equal to 0.
If K is greater than 0, the address of the module is added with K times of a second preset value. For example, when K is 1, it indicates that a number corresponding to the bar code information is smaller than a number corresponding to the bar code information of the module, and then the address of the module is added with a second preset value based on the initial address (i.e., the first preset value in the above embodiment); when K is 2, the number corresponding to the two bar code information is smaller than the number corresponding to the bar code information of the module, and the address of the module is added with twice of the second preset value on the basis of the initial address. In other words, for each piece of barcode information, if the number corresponding to the barcode information is smaller than the number corresponding to the barcode information of the module, the address of the module is added with the second preset value.
When K is 0, the address of the module is still kept to be a first preset value.
Taking the communication network shown in fig. 5 as an example, in fig. 5, the communication network includes a module M1, a module M2, a module M3, a module M4, a module M5 and a module M6, where each module is connected to the bus L. Assume that the numbers corresponding to the bar code information of the module M1, the module M2, the module M3, the module M4, the module M5 and the module M6 are respectively 10, 20, 30, 40, 50 and 60, and the first preset value is 1, and the second preset value is 2.
Specifically, the module M3 is taken as an example of the present module. The module M3 obtains barcode information of other modules (module M1, module M2, module M4, module M5 and module M6) from the bus L. The initialization address of the module M1 is 1, and since the number corresponding to the barcode information of the module M1 is 10 and is smaller than the number 30 corresponding to the barcode information of the module M3, the address of the module M3 becomes 1+1=2; further, since the number corresponding to the barcode information of the module M2 is 20 and is smaller than the number 30 corresponding to the barcode information of the module M3, the address of the module M3 becomes 2+1=3. And the numbers corresponding to the bar code information of the module M4, the module M5 and the module M6 are larger than the numbers corresponding to the bar code information of the module M3, and the address of the module M3 is kept to be 3. In the same manner, the addresses of the module M1, the module M2, the module M4, the module M5 and the module M6 may be obtained, which will not be described herein.
It will be appreciated that in other embodiments, other methods may be used to determine the address of the module from the N bar code information and the bar code information of the module. For example, in the above embodiment, by traversing each barcode information and for each barcode information, if the number corresponding to the barcode information is greater than the number corresponding to the barcode information of the module, the address of the module is added with the second preset value.
Meanwhile, in another embodiment, after the address of the present module is determined by the above method, it is further determined whether the duration from the time when the step of sending the barcode information to the bus is performed to the current time is greater than a third preset duration. Namely, when the module sends bar code information to the bus to start timing and judges whether the timing time length is longer than a third preset time length in real time, wherein the third preset time length is a preset value of a user, the user usually depends on the actual use condition, and the third preset time length is usually longer than or equal to the total time for all the modules to finish determining the address. Typically in power module applications, it may be set to 9s, that is to say the determination of the address of each power module is done within 9 s.
When the timing duration is longer than the third preset duration, all modules do not send bar code information to the bus any more, and at the moment, the fact that the addresses of all the modules are completely determined is indicated. Of course, when the above-mentioned time duration is less than the third preset time duration, the step of returning to the step of not obtaining the bar code information of the present module in the above-mentioned embodiment, and continuing to perform the step of determining the address of the present module according to the bar code information of the present module and the bar code information of the present module until the time duration is greater than or equal to the third preset time duration.
In this embodiment, the timing is started from the transmission of the barcode information to the bus, but in other embodiments, the timing may be started from the transmission of the barcode information request command to the bus.
In summary, first, after each module completes power-up and establishes communication, each module initializes the address of each module to 1, and each module actively transmits a barcode request instruction to the bus. If the module receives bar code request instructions of other modules from the bus, the module resets the address of the module to a first preset value and simultaneously sends bar code information to the bus. If the bar code information request instruction of other modules is not received from the bus, delaying the second preset time, stopping sending the bar code information request instruction after the second preset time, and sending the bar code information to the bus.
If the module receives the bar code information of other modules, the bar code information is stored in the module, and the numbers corresponding to the bar code information of other modules are compared with the numbers corresponding to the bar code information of the module one by one. If the number corresponding to the bar code information of the other modules is larger than the number corresponding to the bar code information of the module, the address of the module is kept unchanged as a first preset value. If the number corresponding to the bar code information of one module is smaller than the number corresponding to the bar code information of the other module, adding a second preset value to the address of the module.
If the module does not receive the bar code information of other modules, delaying the first preset time, stopping sending the bar code information to the bus at the moment when the first preset time is ended, and simultaneously, directly determining the address of the module as a first preset value.
All the steps are required to be completed within a third preset time period, and after the third preset time period is finished, each module does not send bar code information to the bus any more, and the addresses of each module are determined.
Meanwhile, if the existing module on the bus has completed the determination of the address and a new module is connected to the bus, the new module will send a bar code information request instruction. When the existing module on the bus receives the bar code information request instruction sent by the new module, all the modules on the bus (including the existing module and the new module) restart the address determining process, i.e. execute the steps shown in fig. 2-4. Therefore, whether all the modules are powered on simultaneously or all the modules are powered on sequentially, the address of each module can be automatically determined by the method provided by the application, the limit in use is reduced, and the adaptability is higher. Meanwhile, manual operation is not needed, and the reliability of the product can be improved. Further, it is now possible to omit related circuit structures (e.g., dial switches) with respect to the prior art, thereby reducing costs.
It will be appreciated that in the above embodiments, the address of each module is determined by bar code information unique to each module. In other embodiments, the address of each module may be determined by other unique identifiers of each module, for example, the ID number of each module, which is similar to the above embodiments of the present application, and is not repeated herein, insofar as it is easily understood by those skilled in the art.
