Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0053] It should also be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the objects used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those shown or described.

[0054] In recent years, industrial automation has become an important pillar of modern industry. Motors are the basis of industrial automation production lines. Usually, in an automated production line, several motors are set up to realize automated production operations. In order to control the start, stop, reversal and speed of the motor, an inverter unit is set up. The inverter unit achieves the above control by changing the inverter rate. Therefore, the normal and stable operation of the inverter unit is of great significance to ensure the production efficiency of the production line. Once the inverter unit fails, it will cause the production line to shut down for a long time. In view of this, how to quickly resume production of the production line in the event of a failure of the inverter unit has become an urgent problem to be solved.

[0055] At present, the inverter unit is usually set in the electrical cabinet to avoid interference from external factors (such as dust, temperature and static electricity, etc.) so as to make the equipment run more balanced. By equipping the inverter unit with various module spare parts, when the inverter unit fails, the faulty module is located and then replaced with a spare module. However, the above method takes a long time to handle the fault, resulting in a long downtime of the production line, which reduces the work efficiency of the production line.

[0056] In view of this, an embodiment of the present application provides an electrical cabinet fault handling method, so as to reduce the motor downtime after the fault at least to a certain extent when the electrical cabinet fails, thereby improving the work efficiency of the production line.

[0057] The electrical cabinet fault handling method according to the embodiment of the present application is described in detail below with reference to the specific drawings.

[0058] See also Figure 1 , which shows a structural block diagram of an electrical cabinet according to an embodiment of the present application; see Figure 2 , shows a flow chart of an electrical cabinet fault handling method according to an embodiment of the present application.

[0059] like Figure 1 As shown, the electrical cabinet 1 includes a controller 11, a rectifier unit 12, an inverter unit 13 and a standby inverter unit 14. The controller 11 is respectively communicatively connected with the rectifier unit 12 and the inverter unit 13. The first end of the inverter unit 13 is electrically connected to the rectifier unit 12. The second end of the inverter unit 13 is used to electrically connect to the motor 2. The first end of the standby inverter unit 14 is electrically connected to the rectifier unit 12. The standby inverter unit 14 has a second end.

[0060] In some embodiments, there may be multiple inverter units 13, the first end of each inverter unit 13 is electrically connected to the rectifier unit 12, and the second end of each inverter unit 13 is used to electrically connect to the motor 2, wherein one inverter unit 13 can be electrically connected to at least one motor 2. When one inverter unit 13 is electrically connected to multiple motors 2, a copper busbar can be set in the electrical cabinet 1, and the second end of the inverter unit 13 is connected to multiple copper busbar terminals, so that one inverter unit 13 can be electrically connected to multiple motors 2 and control the multiple motors 2.

[0061] It is understandable that the standby inverter unit 14 can be one or more, and can be specifically set according to the needs of the electrical cabinet 1, which is not limited here. Among them, the modules of the standby inverter unit 14 are the same as the modules of the inverter unit 13, so that when the inverter unit 13 fails, the standby inverter unit 14 can directly replace the inverter unit 13 to connect to the motor 2, so as to quickly resume production of the production line and reduce the downtime of the production line.

[0062] It should be noted that, when the inverter unit 13 does not fail, the first end of the standby inverter unit 14 is electrically connected to the rectifier unit 12, and the second end of the standby inverter unit 14 can be suspended, for example, the second end of the standby inverter unit 14 is a cable (connection terminal). When the inverter unit 13 fails, the connection between the inverter unit 13 and the motor 2 is disconnected, and the second end of the standby unit is electrically connected to the motor 2, and insulation is performed (for example, using an insulating tube, a heat shrink tube, etc.).

[0063] It can be understood that since the inverter unit 13 and the standby inverter unit 14 are arranged in the electrical cabinet 1, the cable length reserved for the second end of the standby inverter unit 14 does not need to be too long. For example, when there are multiple inverter units 13, the cable length reserved for the second end of the standby inverter unit 14 is based on the length that can be connected to the second end of the inverter unit 13 that is farthest from the standby inverter unit 14 among the multiple inverter units 13. Therefore, the standby inverter unit 14 can replace the inverter unit 13 to be connected to the rectifier unit 12 and the motor 2.

[0064] like Figure 2 As shown, the embodiment of the present application provides a method for handling a fault in an electrical cabinet 1, which can be executed in the controller 11, and includes but is not limited to:

[0065] Step S10. When the inverter unit 13 fails, the second end of the inverter unit 13 is electrically disconnected from the motor 2, and the second end of the standby inverter unit 14 is electrically connected to the motor 2, an input signal of the inverter unit 13 is obtained;

[0066] Exemplarily, the inverter unit 13 itself has a fault detection mechanism. When one or more modules of the inverter unit 13 fail, it can automatically perform fault detection and locate the faulty module and issue a fault alarm, such as sending a fault alarm signal to the controller 11.

[0067] Exemplarily, the controller 11 can perform fault detection on the inverter unit 13 through the communication status between the controller 11 and the inverter unit 13. For example, if the controller 11 does not receive information from the inverter unit 13 within a preset time period, such as within 30 seconds, 60 seconds, etc., it is considered that the inverter unit 13 has a fault.

[0068] It is understandable that when the inverter unit 13 fails, the operator can be notified to disconnect the second end of the inverter unit 13 from the motor 2 and electrically connect the second end of the standby inverter unit 14 to the motor 2 .

[0069] It should be noted that the inverter unit 13 is used to output current to the motor 2, and the input signal given by the controller 11 to the inverter unit 13 is used to adjust the parameters of the current, such as adjusting the current frequency.

[0070] In some embodiments, there are multiple inverter units 13, and obtaining the input signal of the inverter unit 13 includes:

[0071] Step S11. Acquire a trigger signal sent by a user, wherein the trigger signal is used to indicate a target inverter unit having a fault, wherein the target inverter unit is one of the multiple inverter units 13;

[0072] In some embodiments, the controller 11 is further used to connect to a human-computer interaction terminal, the human-computer interaction terminal 3 has a plurality of identification buttons, and the step of obtaining a trigger signal sent by a user includes:

[0073] The trigger signal sent by the human-computer interaction terminal 3 is obtained, wherein the human-computer interaction terminal 3 generates the trigger signal by receiving a user's trigger operation on a target identification button, and the target identification button is one of the multiple identification buttons.

[0074] It can be understood that a user operation interface is provided at the human-machine interaction terminal 3, and a plurality of identification buttons are provided on the user operation interface, and each identification button is used to represent one of the inverter units 13. For example, each inverter unit 13 is numbered with a number, and it is assumed that there are 4 inverter units 13, numbered 1, 2, 3 and 4, respectively, and the inverter unit 13 No. 2 fails. Then the user can select the identification button corresponding to the inverter unit 13 No. 2 by touching or clicking, and then the human-machine interaction terminal 3 generates a trigger signal after receiving the user's trigger operation on the target identification button, so as to notify the controller 11 of the inverter unit 13 that specifically fails.

[0075] Step S12: Determine the input signal of the target inverter unit according to the trigger signal.

[0076] In some embodiments, determining the input signal of the target inverter unit according to the trigger signal includes:

[0077] Step S121. Acquire the target address information and target status information carried in the trigger signal;

[0078] It can be understood that in order to notify the controller 11 which specific inverter unit 13 has a fault, the human-computer interaction terminal can carry the target address information and target status information of the target inverter unit 13 in the trigger signal when sending a trigger signal to the controller 11, wherein the target address information can be M1.0, M1.1, M1.2, etc., and the target status information can be Boolean data, such as 0 or 1, wherein 0 indicates that no fault has occurred and 1 indicates that a fault has occurred.

[0079] Step S122: locating the target inverter unit according to the target address information, and determining that the target inverter unit fails according to the target state information;

[0080] Step S123: Determine the input signal of the target inverter unit.

[0081] Step S20. Determine the input signal of the inverter unit 13 as the input signal of the standby inverter unit 14, and obtain the output signal fed back by the standby inverter unit 14, wherein the standby inverter unit 14 outputs current to the motor 2 based on the input signal.

[0082] See also Figure 3 , shows a schematic diagram of the communication structure between the controller 11 and each inverter unit 13 in an embodiment of the present application.

[0083] In some embodiments, there are multiple inverter units 13, and the first end of the inverter unit 13 is connected to the controller 11 through a first channel 15A, and the first channel 15A is provided with a first branch channel 16A, and the first branch channel 16A is connected to the first end of the standby inverter unit 14, and the first branch channel 16A is provided with a first signal contact 17A; the second end of the inverter unit 13 is communicatively connected to the controller 11 through a second channel 15B, and the second channel 15B is provided with a second branch channel 16B, and the second branch channel 16B is connected to the second end of the standby inverter unit 14, and the second branch channel 16B is provided with a second signal contact 17B.

[0084] It can be understood that the first channel 15A, the first branch channel 16A, the second channel 15B and the second branch channel 16B refer to channels for signal transmission, which can be wired signal transmission channels or wireless signal transmission channels, which are not limited here. Among them, the first channel 15A is the signal transmission channel between the controller 11 and the first end of the inverter unit 13, the first branch channel 16A is the signal transmission channel between the controller 11 and the first end of the standby inverter unit 14, the second channel 15B is the signal transmission channel between the second end of the inverter unit 13 and the controller 11, and the second branch channel 16B is the signal transmission channel between the standby inverter unit 14 and the controller 11. On this basis, the first signal contact 17A is used to realize the on and off of the first branch channel 16A, and the second signal contact 17B is used to realize the on and off of the second branch channel 16B.

[0085] In some embodiments, determining the input signal of the inverter unit 13 as the input signal of the standby inverter unit 14, and obtaining the output signal fed back by the standby inverter unit 14, includes:

[0086] Step S31. Turning on the target first signal contact 17A and the target second signal contact 17B between the target inverter unit 13 and the standby inverter unit 14, respectively. The target inverter unit is one of the multiple inverter units 13, and the target inverter unit has a fault.

[0087] Step S32: transmitting the input signal of the target inverter unit to the standby inverter unit 14 through the first branch channel 16A, so that the standby inverter unit 14 outputs current to the motor 2 according to the input signal;

[0088] Step S33. Obtain the output signal fed back by the standby inverter unit 14 through the second branch channel 16B to know whether the working status of the standby inverter unit 14 is normal, for example, whether the standby inverter unit 14 is closed, whether the current output by the standby inverter unit 14 to the motor 2 is normal, etc.

[0089] Exemplarily, the controller 11 may be a PLC controller 11 , in which the inputs and outputs of all the inverter units 13 in use are listed in the PLC program, and the inputs and outputs of the faulty inverter units 13 are selected and replaced by triggering different signals (M1.0).

[0090] For example: there are inverter unit A, inverter unit B and inverter unit C, wherein inverter unit A fails, then the first branch channel 16A and the second branch channel 16B between inverter unit A and the standby inverter unit 14 are respectively turned on, and the first branch channel 16A and the second branch channel 16B between other inverter units 13 and the standby inverter unit 14 remain disconnected. In this case, the input signal that the controller 11 should originally transmit to the inverter unit A is transmitted to the standby inverter unit 14 through the first branch channel 16A, and then, the standby inverter unit 14 outputs current to the motor 2 based on the input, and feeds back its own state to the controller 11 based on the second branch channel 16B. Therefore, the embodiment of the present application can realize the rapid replacement of the faulty inverter unit 13 by the standby inverter unit 14 through simple software control, thereby minimizing the downtime of the motor 2 and quickly resuming production of the production line.

[0091] In some embodiments, the electrical cabinet 1 further includes: a backup rectifier unit 18, a first end of the backup rectifier unit 18 is communicatively connected to the controller 11, and a second end of the backup rectifier unit 18 is used to be electrically connected to the inverter unit 13, and the method further includes:

[0092] Step S40. When the rectifier unit 12 fails, the second end of the rectifier unit 12 is electrically disconnected from the inverter unit 13, and the second end of the standby rectifier unit 18 is electrically connected to the inverter unit 13, an input signal of the rectifier unit 12 is obtained;

[0093] Step S50 . Determine the input signal of the rectifier unit 12 as the input signal of the standby rectifier unit 18 , and obtain the output signal fed back by the standby rectifier unit 18 .

[0094] It is understandable that the principle of replacement of the faulty rectifier unit 12 by the backup rectifier unit 18 is similar to the principle of replacement of the faulty inverter unit 13 by the backup inverter unit 14, and will not be repeated here. Therefore, when there are multiple levels of circuit units (such as rectifier units 12 and inverter units 13), the circuit units at each level can be pre-configured with backup circuit units, so that when a circuit unit fails, the circuit unit can be quickly replaced based on the backup circuit unit to reduce the downtime of the motor 2, quickly resume production of the production line, and improve production efficiency of the production line.

[0095] In some embodiments, the method further comprises:

[0096] When the motor 2 stops, the fault diagnosis of the inverter unit 13 that fails is performed online.

[0097] It is understandable that when locating and repairing the specific faulty module of the faulty inverter unit 13, it can be done during the shutdown and maintenance of the motor 2, so as not to affect the normal operation of the production line.

[0098] For example, when repairing the faulty inverter unit 13, the second end of the standby inverter unit 14 can be disconnected from the motor 2, and the second end of the inverter unit 13 used to electrically connect the cable of the motor 2 can be reconnected to the copper bus of the electrical cabinet 1. In addition, the user can select the identification button corresponding to the standby inverter unit 14 on the human-computer interaction terminal 3 so that the standby inverter unit 14 is reset, and the controller 11 is notified to reconnect the faulty inverter unit 13 to the circuit. Thus, the specific fault of the inverter unit 13 can be checked online to improve the maintenance efficiency. The reason is that the faulty inverter unit 13 is still connected to the entire system, but it is no longer used, so it can better diagnose the fault, replace or repair the equipment, and it is more convenient to re-activate the repaired inverter unit 13.
