Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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 some embodiments of the present application, but not all 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.
Referring to fig. 1, fig. 1 is a schematic diagram of modules connected in parallel in the prior art. As shown in fig. 1, there are a total of 7 modules connected in parallel in order from left to right, module a1, module a2, module A3, module a4, module a5, module a6, and module a 7.
In this prior art, 5 dials 1, 2, 3, 4, 5 are provided on each module, and according to the binary principle, in each dial, an upward dial represents a binary "1", no dial (i.e., held at a lower position) represents a binary "0", and from left to right, 5 dials represent 1, 2, 4, 8, 16 in decimal, respectively. Thus, by making different dial settings for different modules so that the addresses of different modules are different, the actual address of each module can be determined. For example, in block a1, if only the switch corresponding to 5 is toggled up, the address of block 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 turned up, the address corresponding to the module A3 is 01+ 02-03; in block a4, the switch corresponding to block a4 is toggled up, and the value corresponding to block a4 is 04; in the module A5, the switch corresponding to 3 and 5 is pushed up, and the value corresponding to the module A5 is 05; in the module 6, the switches corresponding to 3 and 4 are pushed up, so that the value corresponding to the module A6 is 06; in block a7, if the switches corresponding to 3, 4, and 5 are toggled up, the value corresponding to block a7 is 07.
However, in the above manner, after the installation of each module on site is completed, a person familiar with the operation is required to complete the confirmation of the module address. On the one hand, need carry out manual operation, can bring inconvenience in the operation, on the other hand needs to have certain technical requirement to installer, is unfavorable for the later stage to maintain.
Based on this, the application provides a module address determination method, and the method can perform the automatic identification process of the module address by utilizing the self-carried bar code information of each module when the module leaves the factory, does not need manual intervention, has simpler operation, and brings convenience for adding or reducing modules in the later period.
It can be understood that the barcode information carried by each module when the module leaves the factory is unique barcode information, that is, the barcode information between each two modules is different.
Fig. 2 is a flowchart of a module address determining method provided in the present application, where the method is applied to a communication network, the communication network includes at least one module, and the modules are connected by 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 the bar code information to the bus.
After each module is connected to the bus, the first step is that the barcode information of the module is sent to the bus, so that other modules except the module can acquire the barcode 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 a short term for Controller Area Network (CAN), and is one of the most widely used field buses internationally.
Further, in an embodiment, before the step of sending the barcode information to the bus is performed, the module address determination method further includes the steps of:
301: and 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 initialized to a first preset value, for example, the address of the module is initialized to 1. Meanwhile, the module can actively send a bar code information request instruction to the bus, namely, requests to acquire the bar code information sent on the bus by other modules except the module. And, if in the application of the power module, the sending period of the barcode information request command can be set to 400 ms.
302: and if a bar code information request instruction of a module on the bus is received, the step of sending bar code information to the bus is executed.
If a bar code information request command which is not the module can be received from the bus, it is indicated that other modules are connected to the bus except the module, and since the other modules need to know the bar code information of the module and can determine the addresses of the modules, the module needs to send the bar code information of the module to the bus. In addition, if the power module is applied, the transmission cycle for transmitting the barcode information of the power module may be set to 400 ms.
It is understood that in all embodiments of the present application, other modules or other modules generally refer to modules other than the present module that are connected to a bus. And the present module refers to any one of all modules connected to the bus.
303: and if the bar code information request instruction of the module on the bus is not received, delaying a second preset time.
304: and stopping sending the bar code information request instruction to the bus at the moment when the second preset duration is finished, and executing the step of sending the bar code information to the bus.
And if the module does not receive the bar code information request instruction from other modules from the bus, delaying a second preset time. And at the moment when the second preset time length is finished, the module stops sending the bar code information request instruction to the bus and starts sending the bar code information of the module to the bus. For example, if the second preset time is 3S, if the module does not receive the instruction of requesting the barcode information from another module on the bus, after 3S, the module stops initiating 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 present application is applied to a power module, the period for sending the barcode information of the present module may be set to 400 ms.
In summary, after each module is successfully powered on and establishes communication, the module address of each module is initialized to a first preset value, and each module actively sends an instruction for requesting barcode information to the bus. If a bar code request instruction which is not the module can be received, which indicates that at least two modules are connected to the bus, each module is required to send bar code information of the module to the bus. If a request barcode instruction which is not the module is not received, it is very likely that only one module is connected to the bus, the barcode information may be sent to the bus, or not sent, and no limitation is made here.
202: and if the bar code information of the non-module is not received, delaying the first preset time.
203: and at the moment when the first preset duration is finished, stopping sending the bar code information to the bus, and determining the address of the module as a first preset value.
After sending the bar code information request instruction to the bus, if the bar code information of other modules is not received, only the module is determined to be connected to the bus, and then the bar code information can be stopped from being sent to the bus. And then delaying the first preset time, stopping sending the bar code information to the bus at the moment when the first preset time is finished, and directly setting the address of the module as a first preset numerical value.
In conjunction with the above embodiments, the first preset value is 1 for example. After the modules are powered on and communication is established, the addresses of the initialized modules are all 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 be 1 after the bar code information is stopped being sent to the bus. It should be understood that before sending the barcode information to the bus, if a barcode request instruction from another module is received, the address of the module may also be actively reset to 1, so as to ensure that the initial value of the module is 1.
204: and if at least one piece of bar code information of the non-local module is received, determining the address of the module according to the received at least one piece of bar code information of the non-local module.
Suppose that the module receives bar code information of N non-modules (other modules), where N is a natural number greater than 0. Firstly, the N pieces of bar code information are stored in the corresponding memory space of the module so as to be used for determining the address of the module subsequently. Then, the N pieces of bar code information can be combined with the bar code information of the module to determine the address of the module.
Specifically, in an embodiment, the following method is adopted to determine the address of the module through the N pieces of bar code information and the bar code information of the module, as shown in fig. 4, the method includes:
401: and judging whether the bar code information of the module has bar code information of which the number corresponding to at least one bar code information is smaller than the number corresponding to the bar code information of the module.
402: if yes, traversing each bar code information, and if the number corresponding to the bar code information is smaller than the number corresponding to the bar code information of the module, adding a second preset numerical value to the address of the module.
403: if not, the address of the module is kept unchanged.
In the module, the stored numbers corresponding to the barcode information of the other modules and the numbers corresponding to the barcode information of the module are sorted in size, so that the situation that the numbers corresponding to the barcode information are smaller than the K pieces of barcode information of the numbers corresponding to the barcode information of the module in the N pieces of barcode information of the other modules can be determined, wherein K is a natural number which is smaller than or equal to N and larger than or equal to 0.
If K is larger 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 there is a number corresponding to a piece of barcode information smaller than a number corresponding to the barcode information of the module, the address of the module is added with a second preset value on the basis of the initial address (i.e., the first preset value in the above embodiment); and 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 a second preset value on the basis of the initial address. In other words, for each bar code information, if the number corresponding to the bar code information is smaller than the number corresponding to the bar code information of the module, the address of the module is added with a second preset numerical value.
When K is 0, the address of the module is still kept as the 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, wherein each module is connected to a bus L. Assume that the numbers corresponding to the barcode information of the module M1, the module M2, the module M3, the module M4, the module M5 and the module M6 are 10, 20, 30, 40, 50 and 60, respectively, and assume that the first preset value is 1 and the second preset value is 2.
Specifically, the module M3 will be described as an example of the present module. The module M3 acquires 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, which is smaller than the number 30 corresponding to the barcode information of the module M3, the address of the module M3 is changed to 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 is 2+1 — 3. And the numbers corresponding to the barcode information of the module M4, the module M5 and the module M6 are all larger than the numbers corresponding to the barcode 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 is not described herein again.
It is understood that in other embodiments, other methods may be used to determine the address of the module by using 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 second preset value is added to the address of the module.
Meanwhile, in another embodiment, after the address of the module is determined by the above method, it is further determined whether a time period from a time when the step of sending the barcode information to the bus is started to a current time is longer than a third preset time period. That is, timing is started when the module sends the barcode information to the bus, and whether the timing duration is longer than a third preset duration is judged in real time, wherein the third preset duration is a preset value of a user and is usually determined by the user according to actual use conditions, and the third preset duration is usually required to be longer than or equal to the total time of all modules for completing address determination. In general, in the application of the power supply module, it can be set to 9s, that is, the determination of the address of each power supply module is completed within 9 s.
When the timing duration is longer than the third preset duration, all the modules do not send the bar code information to the bus any more, and the address of each module is determined at the moment. Of course, when the timing duration is less than the third preset duration, the step of not determining each barcode information of the module in the above embodiment is returned, and the step of determining the address of the module according to each barcode information of the module and the barcode information of the module is continuously executed until the timing duration is greater than or equal to the third preset 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 the modules are powered on and establish communication, the address of each module is initialized to 1, and each module actively sends a barcode request instruction to the bus. If the module receives a bar code request instruction of other modules from the bus, the module resets the address of the module to be a first preset value and simultaneously sends bar code information to the bus. If the bar code information request instructions of other modules are not received from the bus, delaying a second preset time, stopping sending the bar code information request instructions 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 in size. If the number corresponding to the bar code information of other modules is larger than the number corresponding to the bar code information of the module, the address of the module is kept unchanged to be the first preset numerical 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 module in other modules, adding a second preset numerical 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 over, and simultaneously directly determining the address of the module as a first preset numerical value.
All the steps need to be completed within a third preset time, and after the third preset time is finished, each module does not send barcode information to the bus any more, and the address of each module is determined.
Meanwhile, if the existing module on the bus finishes the determination of the address and a new module is connected to the bus, the new module sends a bar code information request instruction. When the existing module on the bus receives the barcode information request command sent by the new module, all modules (including the existing module and the new module) on the bus restart the address determination process, i.e., execute the steps shown in fig. 2 to fig. 4. Therefore, no matter all the modules are powered on simultaneously or all the modules are powered on sequentially, the method provided by the application can automatically determine the addresses of all the modules, reduces the limitation in use and has high adaptability. Meanwhile, manual operation is not needed, and the reliability of the product can be improved. Moreover, with respect to the prior art, the related circuit structure (for example, a dial switch) can be omitted, so that the cost can be reduced.
It is understood that, in the above-described embodiment, the address of each module is determined by the barcode information unique to each module. In other embodiments, the address of each module may also be determined by other unique identifiers of each module, for example, the ID number of each module, and the specific implementation process is similar to that in the above embodiments of the present application, which is within the scope easily understood by those skilled in the art, and is not described here again.
