Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Fig. 1 is a schematic flow chart of an implementation of a method for determining a machine number of a charging module according to an embodiment of the present invention, which is described in detail below.
The other charging modules refer to charging modules on the charging pile except the current charging module
As shown in fig. 2, in the communication architecture, all charging modules provided on the charging pile perform information communication via the CAN bus, and the current charging module is described as an execution subject.
Optionally, this step is an automatic sorting process, and may include:
when a charging pile is powered on, receiving preset numbers sent by each charging module on the electric automobile charging pile through a CAN bus;
and automatically sequencing according to the current preset number and all the received preset numbers, determining the current machine number corresponding to the current charging module, and sending the current machine number to the CAN bus.
After obtaining the current machine number of the user, whether the current machine number is the final machine number of the user needs to be detected.
Detecting whether the current charging module successfully obtains a final machine number;
and when the current charging module successfully obtains the final machine number, determining that the automatic sequencing is completed.
After determining that the automatic sorting is completed, further comprising: and setting the automatic sorting completion flag bit, and then resetting to complete the current automatic sorting process.
After the detecting whether the current charging module successfully obtains the final machine number, the method further includes:
and when the current charging module succeeds and does not obtain the final machine number, determining that automatic sequencing is not completed, clearing the automatic sequencing completion flag bit, and then resetting to complete the current automatic sequencing process.
In this embodiment, when the power is turned on, each charging module sends a preset number to the CAN bus. The preset serial number may be a unique serial number before the charging module leaves the factory, and the serial number may be formed by combining a series of numbers and letters, but the serial number does not have uniqueness, fixity and non-repeatability. The serial numbers are used for automatically sequencing and determining the machine numbers of the charging modules, so that the defects existing in a manual sequencing mode can be overcome, wherein the manual sequencing mode is to determine the machine number of each charging module by adopting a hardware circuit or a dial switch and the like in the prior art and determine the machine number by manually inputting the machine number before each charging module leaves a factory. Namely, the automatic sequencing mode can reduce the hardware development cost, the labor cost and the possibility of error operation of personnel.
For example, if the current charging module is the charging module No. 2, the current charging module can receive serial numbers sent by the charging module No. 1, the charging module No. 3 and the subsequent charging modules, automatically sort the serial numbers according to the serial numbers of all the charging modules, and sort the serial numbers according to a sequence from small to large or a sequence from large to small to obtain the machine numbers of the current charging module.
Optionally, before this step, the method may further include:
detecting whether corresponding machine numbers sent by other charging modules are received;
when receiving corresponding machine numbers sent by other charging modules, marking the machine numbers, and detecting whether machine number repeated faults exist or not;
when the repeated faults of the machine numbers are not detected and the automatic sequencing is completed, whether the faults of the same host occur or not is detected;
and when the same host fails, recording the acquired corresponding phone numbers sent by the other charging modules, and searching and storing the main charging module.
And when the same host fails, re-determining the main charging module according to the final machine number and the machine number of the charging module with the same host failure, and storing the master-slave mark of the current charging module.
In an embodiment, when the process starts, it may be first detected whether the corresponding machine numbers sent by other charging modules are received, when the corresponding machine numbers sent by other charging modules are received, it indicates that the operation of automatic sorting, that is, the operation of step 101, may be completed currently, and when the corresponding machine numbers sent by other charging modules are not received, the operation of step 101 needs to be performed.
Optionally, when the repeated number failure is not detected and the automatic sorting is completed, detecting whether the same host failure occurs may include:
when the repeated faults of the machine numbers are not detected, whether automatic sequencing is finished or not is detected; and after the automatic sequencing is finished, detecting whether the same host fails or not. Here, the same host fails, i.e., two hosts are present.
When the same host fails, the host needs to be determined again. In this embodiment, re-determining the main charging module according to the final machine number and the machine number of the charging module with the host failure may include: determining the charging module with the smaller number of the two modules as a main charging module, and determining the other charging module as a slave charging module; or the charging module with the larger size in the two charging modules is determined as the main charging module, and the other charging module is determined as the auxiliary charging module.
The master charging module and the slave charging module are determined to be master seeking operation and are actually the preprocessing process of current sharing, the current sharing process of the master charging module and the slave charging module is a process that all slave charging modules regulate self current according to the average current sent by the master charging module, and therefore the current sharing process needs to distinguish whether the obtained information is the average current or the output current, namely the master-slave performance of the received information.
In order to reduce the data transmission pressure of the CAN bus, the information sent to the CAN bus by each charging module is sent by using one frame.
And 102, receiving corresponding machine numbers sent by other charging modules, deleting repeated machine numbers when machine number repeated faults are detected, reordering according to the current preset number and the preset number sent by the charging module corresponding to the repeated machine numbers, and determining the final machine number corresponding to the current charging module.
After each charging module determines the own phone number, the own phone number is sent to the CAN bus in real time so as to inform other charging modules on the charging pile, and the problem that the same phone number is repeatedly occupied is avoided.
Optionally, when a repeated number failure is detected, deleting a repeated number, and determining a final number corresponding to the current charging module according to the current preset number and the preset number sent by the charging module corresponding to the repeated number, where the method includes:
when the repeated machine number fault is detected, deleting the current machine number of the current charging module, and sending the current preset number of the current charging module to the CAN bus;
and when receiving a preset number sent by the charging module with the repeated fault of the machine number, reordering according to the current preset number and the preset number sent by the charging module with the repeated fault of the machine number, and determining the final machine number corresponding to the current charging module.
It should be noted that, in order to avoid mutual interference between the automatic sorting and the main searching process, dynamic adjustment of stability, same-machine number fault and host repeated fault of the current-sharing preprocessing process is realized, so that the automatic sorting and main searching process is controlled in logic sequence and smoothly switched.
The conditions for the sequence control are:
the serial number is not continuously sent to the CAN bus after the automatic sequencing is finished;
the number corresponding to the charging module needs to be continuously sent on the CAN bus.
The key of the smooth switching is as follows:
and when the machine number has repeated faults, ending the current process, entering an automatic sequencing process, and performing a main searching process after the automatic sequencing process is finished.
When repeated faults of the host computer occur, the main charging module is directly re-determined in the current process according to the size of the host computer.
Optionally, when each charging module sends a serial number to the CAN bus, the master-slave mark and current information of each charging module CAN be sent in real time, wherein when the charging module is the master charging module, the current information is an average current, and when the charging module is the slave charging module, the current information is an output current.
Namely, the current charging module receives the corresponding machine number, the master-slave mark and the current information of each charging module sent by each charging module in real time.
The method for determining the number of the charging module is described below by a specific embodiment, as shown in fig. 3.
And after the process is started, detecting whether the corresponding machine number sent by other charging modules is received.
When the corresponding machine numbers sent by other charging modules are not received, the automatic sequencing is detected whether to be finished or not if the automatic sequencing is possibly not finished;
and when the automatic sequencing is not finished, determining a current machine number corresponding to the current charging module according to the current preset number and the acquired preset numbers sent by other charging modules on the charging pile, and sending the current machine number to the CAN bus.
Detecting whether the final machine number is successfully obtained or not;
and if the current charging module successfully obtains the final machine number, determining that automatic sequencing is completed, setting an automatic sequencing completion flag bit, and then resetting to complete the current automatic sequencing process. The reset refers to clearing a machine number marking variable, clearing an online module total count, storing a machine number of the machine, clearing a fault flag and storing a function flag after storing the fault flag, wherein the clearing of the fault flag is to clear the same machine number fault after storing the same machine number fault so as to restart the next process, and the function flag may include: a sorting completion flag bit, a master seeking completion flag bit, a master-slave flag and the like;
and if the current charging module succeeds in not obtaining the final machine number, determining that automatic sequencing is not completed, resetting an automatic sequencing completion flag bit, and then resetting to complete the current automatic sequencing process. The reset is the same as the reset meaning, but the automatic sorting completion flag bit is not set;
when the automatic sequencing is completed, detecting whether the main charging module is repeated;
and when the main charging module is repeated, re-determining the main charging module according to the final machine number and the machine number of the charging module with the fault of the host, storing the parameters of the current charging module, and ending the current process. The parameters refer to the number of online modules, the functional status flags and the failure flags, wherein the functional flags may include: a sorting completion flag bit, a master seeking completion flag bit, a master-slave flag and the like;
and when the repetition of the main charging module does not occur, recording the acquired corresponding machine numbers sent by the other charging modules, searching and storing the main charging module, and ending the current process. The parameters stored here are the same as described above;
when receiving corresponding machine numbers sent by other charging modules, carrying out same machine number processing and machine number marking processing, and detecting whether machine number repeated faults of the charging modules occur;
and when the repeated faults of the machine number of the charging module do not occur, the step of detecting whether the automatic sequencing of the serial numbers is finished is carried out.
And when the machine number of the charging module has repeated faults, deleting the current machine number of the current charging module, resetting the automatic sequencing completion flag bit, and then resetting to finish the current process. In the next process, the charging module with the machine number repeated fault sends the serial number of the charging module to the CAN bus again, whether the CAN bus receives the machine number is detected, the charging module with the machine number repeated fault sends the serial number of the charging module, and when the current charging module receives the preset serial number sent by the charging module with the machine number repeated fault, the current charging module carries out reordering according to the current preset serial number and the preset serial number sent by the charging module with the machine number repeated fault, and the final machine number corresponding to the current charging module is determined.
It should be noted that, since the corresponding serial number and the master-slave flag of the charging module and the current information of each charging module need to be sent to the CAN bus in real time, the next process CAN be started after the current process is finished.
In the above embodiment, the automatic sorting process and the main seeking process are separated, and do not interfere with each other, so that the stability of the current-equalizing preprocessing process, the dynamic adjustment of the same-number fault and the repeated fault of the host, and the smooth switching between the automatic sorting and the main seeking are realized.
According to the method for determining the machine number of the charging module, the current machine number corresponding to the current charging module is determined according to the current preset number and the obtained preset numbers sent by other charging modules on the charging pile, and the current machine number is sent to the CAN bus, so that the corresponding machine number CAN be obtained through automatic sequencing, the hardware design and development cost, the labor cost and the possibility of operation errors of personnel are reduced, and the problems in the prior art are avoided. And when the corresponding machine numbers sent by the other charging modules are received, when the machine number repeated fault is detected, the repeated machine numbers are deleted, and the final machine number corresponding to the current charging module is determined according to the current preset number and the preset number sent by the charging module corresponding to the repeated machine numbers, so that the problem of repeated machine numbers can be avoided. The method can realize that the final host is re-determined according to the number when the main charging module repeatedly fails. The automatic sequencing and main searching process is executed in a sequential control mode, so that mutual influence and interference can be avoided.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
