Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
As shown in fig. 1, the present invention provides a method for allocating an axle number of a multi-pass frequency converter, where the multi-pass frequency converter includes a rectifying device 10 and at least two inverting devices 20, and the at least two inverting devices 20 are connected to the rectifying device 10 in a cascade manner, and in the method, the rectifying device can automatically allocate an axle number to an inverting device according to a physical location of the inverting device without any manual setting. The method is applied to the rectifying device and comprises the following steps:
s110: sending a shaft number scanning signal with an inverted shaft number to inversion equipment adjacent to the rectification equipment, so that at least two cascaded inversion equipment set the shaft number according to the shaft number scanning signal and a preset shaft number distribution strategy; wherein, the preset shaft number allocation strategy is as follows: after receiving the axle number scanning signal from the uplink interface, the inverter equipment firstly judges whether the axle number is set by the inverter equipment, if not, the inverter axle number carried in the axle number scanning signal is set as the axle number of the inverter equipment, and a response signal indicating that the axle number is successfully set is returned from the uplink interface; otherwise, forwarding the shaft number scanning signal from a downlink interface;
in the invention, the rectifying equipment distributes the shaft number to the inverting equipment in a scanning mode. After the multi-pass frequency converter is powered on, restarted or issued with a scanning command, the rectifying equipment issues an axis number scanning signal to the adjacent first inversion equipment, wherein the axis number scanning signal comprises an inversion axis number.
It should be noted that the shaft number is a number of a device (including a rectifying device and an inverting device), and may also be called a station number, or another name capable of representing a device. In the invention, the number of the inversion axis refers to the number of the inversion equipment axis.
S120: if a response signal that the shaft number of a certain inverter device fed back by the inverter device adjacent to the rectifier device is successfully set is received within a preset time, a next inverter shaft number is generated according to a preset rule on the basis of the inverter shaft number, a shaft number scanning signal carrying the next inverter shaft number is sent to the inverter device adjacent to the rectifier device again, and the above process is repeatedly executed until a response signal that the shaft number of a certain inverter device fed back by the inverter device adjacent to the rectifier device is successfully set is not received within the preset time.
After the rectifying device sends the shaft number scanning signal each time, the corresponding response signal needs to be waited for within the preset time, and the response signal may indicate that the shaft number is successfully set, may indicate that the shaft number is failed to set, and may not receive any signal within the preset time. And only after receiving a response signal indicating that the shaft number is successfully set, the rectifying device can continuously send a shaft number scanning signal with a next inverted shaft number to the first inverting device. It should be noted that, since all the inverter devices are connected to the rectifier device in series, the rectifier device can only communicate with other inverter devices through the first inverter device adjacent to the rectifier device.
In addition, the next inversion axis number is generated by changing according to a specific rule on the basis of the last inversion axis number. Of course, the inversion axis number sent for the first time is the initial inversion axis number, and the last inversion axis number does not need to exist. The specific regular change may be an increasing rule, a decreasing rule or other rules, for example, the specific regular change means that 1 is added each time, the initial inversion axis number is 1, the inversion axis number carried in the axis number scanning signal sent for the second time is 2, the inversion axis number carried in the axis number scanning signal sent for the third time is 3, and so on.
Because the inverter device that the rectifier device can drive has an upper limit, assuming that the upper limit is L, the upper limit of the shaft number generated by the inverter device according to a specific rule is M, in a preferred embodiment, after the next inverter shaft number is generated, or before the rectifier device continues to send a shaft number scanning signal with the next inverter shaft number to the first inverter device, it is determined whether the inverter shaft number exceeds the upper limit M of the shaft number, if so, the transmission of the shaft number scanning signal is stopped, and if not, the transmission of the shaft number scanning signal is continued.
S130: and stopping sending the shaft number scanning signal.
When the response signal indicating that the setting of the shaft number is successful is not received (at this time, the response signal indicating that the setting of the shaft number is failed may be received, or the corresponding response signal is not received within the preset time), the rectifying device stops sending the shaft number scanning signal, that is, the scanning is finished, and the setting of the shaft number of the inverter device is finished.
The total number of the inverter equipment is stored after each scanning of the rectification equipment, so that each scanning process of the rectification equipment is also a process for finding whether the inverter equipment has faults or not. In a preferred embodiment, the method further comprises:
and after the transmission of the shaft number scanning signal is stopped, acquiring the inversion shaft number successfully set for the last time, calculating the total number N of the inversion equipment, and if the N is less than the total number stored in the rectification equipment, giving an alarm by the rectification equipment. For example, the number of inverter devices obtained by scanning after the device is restarted is 5, and the number of stored inverter devices is 7, which indicates that the 6 th device has a fault, so that a response signal indicating that the shaft number is successfully set is not received, and therefore an alarm needs to be sent to notify the user.
In a preferred embodiment, the method further comprises:
and after the axle number scanning signal is stopped being sent, sending configuration information to each inverter device, wherein the configuration information is stored on the rectifier device by taking the axle number of the inverter device as an index. Therefore, when a certain inverter device breaks down and a new inverter device is replaced, a professional person is not needed to perform parameter setting and other operations on the new inverter device, and the maintenance cost is greatly saved.

And then the rectifying device sends the shaft number data 2, after the shaft number of the first inverter device is set, the first inverter device is only responsible for transferring the communication data, so that the first inverter device directly transfers the shaft number data 2 sent by the rectifying device through the downlink interface 22 after receiving the shaft number data 2 from the uplink interface 21, at this time, the second inverter device connected in series behind the first inverter device receives the data and sets the data as the shaft number of the second inverter device, meanwhile, a response signal is returned to the first inverter device, and the first inverter device returns the response signal to the rectifying device, thus, the shaft number setting of the second inverter device is completed. And the rest is repeated until the last inversion equipment.
