Detailed Description
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. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
Since the large-scale civilian use of lasers, the industry has seen a range of laser applications such as laser welding, laser cutting, laser cleaning, and the like. For example, with the rise of the new energy automobile industry, the demand for laser welding has exploded. For simultaneous operation of multiple production lines, a conventional manner is to provide a laser for each production line. However, with the requirements of cost reduction and efficiency improvement, the welding production line of the new energy automobile has a requirement on multiple purposes, namely, a limited laser is utilized to serve as many production lines as possible.
For the existing one-machine-multi-purpose scheme of the laser, a mode that a control system of a time-sharing optical shutter controls the time-sharing optical shutter is often adopted, so that the effect that light beams can be transmitted in a time-sharing mode is achieved. The hardware and software in the control system of the time-sharing optical shutter are customized according to the specific structure of the time-sharing optical shutter. If the specific structure of the time-sharing optical shutter is changed, the control system of the corresponding time-sharing optical shutter also needs to be changed. The control system of the time-sharing optical shutter in the related art is not compatible with various time-sharing optical shutters, and the control system of the time-sharing optical shutter, that is, the control system of the time-sharing optical shutter, has poor expandability.
For example, a control system of a two-way time-sharing optical shutter is adapted to a two-way time-sharing optical shutter, and the control system of the two-way time-sharing optical shutter is not adapted to a four-way time-sharing optical shutter. Meanwhile, the difficulty of integration and debugging after integration of a control system corresponding to the plurality of time-sharing optical shutters are increased, and the control system of the integrated time-sharing optical shutters has irreproducibility, so that the production efficiency is greatly reduced.
In the related art, referring to fig. 1, fig. 1 is a schematic structural diagram of a time-sharing optical shutter according to an embodiment of the present application. The time-sharing optical shutter 1 comprises an input coupling joint 11, a collimating lens group 12, a plurality of rotatable reflecting mirrors 13, a water-cooling absorber 15, a plurality of focusing lens groups 141 and a plurality of output coupling joints 142, wherein each focusing lens group 141 corresponds to one output coupling joint 142, the input coupling joint 11, the collimating lens group 12, all the rotatable reflecting mirrors 13, all the focusing lens groups 141 and all the output coupling joints 142 are assembled into a whole according to an optical path in sequence, and the water-cooling absorber 15 is used for absorbing residual light beams. The plurality of focusing lens groups 141 and the plurality of output coupling tabs 142 in the time-sharing optical shutter 1 form a plurality of light-emitting channels 14. Wherein each rotatable mirror 13 corresponds to a focusing lens group 141 and an output coupling joint 142. The light beam enters the time-sharing optical shutter 1 from the input coupling joint 11, is collimated by the collimating lens to obtain a collimated light beam, can be reflected on any one of the rotatable reflecting mirrors to obtain a reflected light beam, and is output through the corresponding focusing lens group 141 and the corresponding output coupling joint 142, so that the time-sharing light-emitting effect is achieved, and the light beam is focused and then coupled into a processing system in the optical fiber cable for rear-end laser processing locked on the output coupling joint 142. In some cases, a plurality of rotatable mirrors 13 are disposed on the extension of the collimated beam. Each rotatable mirror 13 has a first position and a second position, the rotatable mirror 13 being capable of reflecting a straight beam when the rotatable mirror 13 is in the first position; when the rotatable mirror 13 is in the second position, the rotatable mirror 13 is clear of the collimated beam. It will be appreciated that in order for one of the rotatable mirrors 13 to normally reflect light, the other rotatable mirror 13 needs to be in a position to avoid the collimated beam. For example, referring to fig. 2, fig. 2 is a schematic optical path diagram of a time-sharing optical shutter according to the related art in an embodiment of the present application. The time-sharing optical shutter 1 has a first rotatable mirror 131, a second rotatable mirror 132 and a third rotatable mirror 133, where the first to third rotatable mirrors 133 are located on the extension line of the collimated light beam, and when the second rotatable mirror 132 is in the first position, i.e. the second rotatable mirror 132 is aligned with the collimated light beam to reflect, the first rotatable mirror 131 and the third rotatable mirror 133 need to be in the second position, so that the first rotatable mirror 131 and the third rotatable mirror 133 can avoid the collimated light beam, thereby avoiding interference to the process of reflecting the collimated light beam by the second rotatable mirror 132.
Above, the time-sharing optical shutter 1 further has a plurality of motors 16, and each motor 16 drives one rotatable mirror 13 to move, so that the rotatable mirror 13 is in the first position or the second position.
The time-sharing shutter 1 comprises a number of rotatable mirrors 13, a number of motors 16 and a number of sensors. Based on this structure, the time-sharing shutter module corresponds to the structure of the time-sharing shutter 1, so as to control each motor 16 and monitor the state of the time-sharing shutter 1. In the related art, the time-sharing optical shutter module corresponds to one time-sharing optical shutter 1 to control one or more rotating mirrors in the time-sharing optical shutter 1, and the time-sharing optical shutter module has a control module, a motor driving module electrically connected with the control module, and a monitoring module. Accordingly, the number of motor drive modules and monitor modules to which the time-sharing optical shutter 1 module is assembled varies depending on the number of rotatable mirrors 13 and the monitor requirement.
Therefore, the embodiment of the application provides a control system of the time-sharing optical gate, which selects the time-sharing optical gate modules of related technologies and links the time-sharing optical gate modules together, so that the control system can adapt to the specific structures of various time-sharing optical gates, and reduces the material cost and the labor cost. The following description is made in detail with reference to the accompanying drawings.
In the embodiment of the present application, please refer to fig. 3, fig. 3 is a schematic structural diagram of a time-sharing optical shutter according to the embodiment of the present application. The time-sharing optical shutter 2 includes an input coupling joint 21, a collimating lens group 22, a plurality of sub-time-sharing optical shutters 23, and a water-cooling absorber 24, each time-sharing optical shutter 2 includes a plurality of rotatable mirrors 232, a plurality of focusing lens groups 2331, and a plurality of output coupling joints 2332, and the water-cooling absorber 24 is used for absorbing residual light beams. The plurality of focusing lens groups 2331 and the plurality of output coupling connectors 2332 in the time-sharing optical shutter 2 form a plurality of light-emitting channels 233. Wherein each rotatable mirror 232 corresponds to a focusing lens group 2331 and an output coupling 2332. The light beam enters the time-sharing optical shutter 2 from the input coupling joint 21, is collimated by the collimating lens group 22 to obtain a collimated light beam, can be reflected on any one of the rotatable reflecting mirrors 232 to obtain a reflected light beam, and is output by the corresponding focusing lens group 2331 and the corresponding output coupling joint 2332 to achieve the effect of time-sharing light output, and is coupled into a processing system in the optical fiber cable for rear-end laser processing locked on the output coupling joint 2332 after being focused. It is understood that a plurality of rotatable mirrors 232 may be disposed on the extension of the collimated beam. Each rotatable mirror 232 has a first position and a second position, the rotatable mirror 232 being capable of reflecting a straight beam when the rotatable mirror 232 is in the first position; when the rotatable mirror 232 is in the second position, the rotatable mirror 232 is clear of the collimated beam. It will be appreciated that in order for one of the rotatable mirrors 232 to normally reflect light, the other rotatable mirrors 232 need to be positioned so as to avoid the collimated beam.
It can be appreciated that, please continue to refer to fig. 3, fig. 4 and fig. 5, fig. 4 is a first block diagram of the control system of the time-sharing optical shutter according to the embodiment of the present application, and fig. 5 is a second block diagram of the control system of the time-sharing optical shutter according to the embodiment of the present application. Since the time-sharing shutter control system 100 directly selects the time-sharing shutter modules 120, the time-sharing shutter modules 120 are linked to act on one time-sharing shutter 2. So that it is divided according to the control range of the time-sharing shutter module 120, one time-sharing shutter 2 includes at least one sub-time-sharing shutter 23, that is, one or more sub-time-sharing shutters 23 together form the time-sharing shutter 2 in the embodiment of the present application. The sub-time-division shutter 23 may have a plurality of states such as light-emitting, closing, or cutting. Wherein when the sub-time-sharing shutter 23 is in the light-out state, one of the rotatable mirrors 232 in the sub-time-sharing shutter 23 is capable of reflecting the collimated light beam, and the light is capable of being emitted from the corresponding light-emitting channel 233. When the sub-time-sharing shutter 23 is in the closed state, all rotatable mirrors 232 in the sub-time-sharing shutter 23 avoid the collimated light beam, i.e. the sub-time-sharing shutter 23 is not aligned with the straight light beam. When the sub-time division shutter 23 is in the off state, the water-cooled absorber 24 in the sub-time division shutter 23 absorbs the straight beam.
With continued reference to fig. 3 and 5, the time-sharing optical shutter 2 includes at least one sub-time-sharing optical shutter 23, and the control system 100 of the time-sharing optical shutter 2 includes a system bus 110 and at least one time-sharing optical shutter module 120. The time-sharing optical shutter module 120 is electrically connected to the corresponding sub-time-sharing optical shutter 23, the monitoring module 123 of the time-sharing optical shutter module 120 is configured to monitor the current state of the corresponding sub-time-sharing optical shutter 23 to obtain state information, and the time-sharing optical shutter module 120 is electrically connected to the system bus 110, where the time-sharing optical shutter module 120 is configured to receive a driving instruction, and control the corresponding sub-time-sharing optical shutter 23 to emit light, close or cut off according to the driving instruction and the state information.
The sub-time-sharing optical shutter 23 includes a motor 231, a rotatable mirror 232, and a monitoring device, the motor 231 is connected with the rotatable mirror 232, the time-sharing optical shutter module 120 includes a control module 121 and a motor driving module 122, the motor driving module 122 and the monitoring module 123 are respectively electrically connected with the motor 231, the motor driving module 122 is used for controlling the motor 231 to drive the rotatable mirror to rotate, the monitoring device is used for monitoring current position information of the rotatable mirror, the control module 121 is respectively electrically connected with the system bus 110, the monitoring device and the motor driving module 122, and the control module 121 is used for: receiving a driving instruction; obtaining state information according to the current position information of the rotary reflector; according to the driving instruction and the state information, the motor driving module 122 is controlled to transmit an electric signal, and the corresponding sub-time division optical shutter 23 is controlled to emit light, close or cut off.
The system bus 110 is used to transmit drive instructions. Each time-division shutter module 120 corresponds to one sub-time-division shutter 23. Each time-division optical gate module 120 is electrically connected to the system bus 110, and each time-division optical gate module 120 includes a control module 121, a motor driving module 122, and a monitoring module 123. The motor driving module 122 is for supplying an electric signal to the motor 231 to drive the motor 231. The monitoring module 123 is configured to monitor status information of the corresponding sub-time division shutter 23. The control module 121 is electrically connected to the motor driving module 122 and the monitoring module 123, respectively. The control module 121 of each sub-time division optical shutter 23 is configured to obtain a driving command and state information of the corresponding sub-time division optical shutter 23 transmitted on the system bus 110, and transmit an electrical signal to the motor 231 according to the driving command and the state information of the sub-time division optical shutter 23.
With continued reference to fig. 5, the number of the time-sharing optical shutter modules 120 may be one or more. If the number of the time-division shutter modules 120 is plural (two or more), the plurality of time-division shutter modules 120 are connected to the system bus 110. Wherein the system bus 110 transmits a driving instruction. After receiving the driving command and according to the state information fed back by the monitoring module 123, the control module 121 transmits an electrical signal to the corresponding motor 231, so as to solve the problem of poor expansibility of the control system 100 of the time-sharing optical shutter in the related art. The system bus 110 may be a CAN bus, 485 bus, or ethernet.
For example, the number of the time-sharing optical shutter modules 120 is three, and is denoted as a first time-sharing optical shutter module 124, a second time-sharing optical shutter module 125, and a third time-sharing optical shutter module 126. The first time-sharing optical shutter module 124, the second time-sharing optical shutter module 125, and the third time-sharing optical shutter module 126 are all electrically connected to the system bus 110.
The first time-sharing optical shutter module 124 includes a first control module 1241, a first motor driving module 1242, and a first monitoring module 1243. The second time-division optical gate module 125 includes a second control module 1251, a second motor drive module 1252, and a second monitor module 1253. The third time-sharing optical shutter module 126 includes a third control module 1261, a third motor driving module 1262, and a third monitoring module 1263.
When the command transmitted on the system bus 110 drives the rotatable mirror 232 in the second sub-time division shutter 23 to the second position, the second control module 1251 of the second time division shutter module 125 receives the driving command, and receives the status information provided by the second monitor module 1253 of the second time division shutter module 125; if the state information is that the second sub-time division shutter 23 is in the working state, the second control module 1251 transmits an electrical signal to the second motor driving module 1252 so that the corresponding motor 231 is in the locking state; if the status information is that the second sub-time division shutter 23 is in the inactive state, the second control module 1251 transmits an electrical signal to the second motor driving module 1252 to cause the motor 231 to be in the operating state. At the same time, the first monitoring module 1243 of the first time-sharing optical shutter module 124 and the third monitoring module 1263 of the third time-sharing optical shutter module 126 monitor the state information of the corresponding sub-time-sharing optical shutter 23, respectively. If the monitoring module 123 of the first time-sharing optical shutter module 124 monitors that the first sub-time-sharing optical shutter 23 is in the working state at this time, an electrical signal is transmitted to the motor driving module 122, so that the motor driving module 122 drives the motor 231 to be in the stop state, thereby avoiding the interference of the first sub-time-sharing optical shutter 23 on the second sub-time-sharing optical shutter 23.
It is understood that the motor driving module 122 can change the operation state of the motor 231 under the control of two electrical signals, namely, the enable signal and the pulse signal, sent by the control module 121. The operation state of the motor 231 is divided into an operation state, a locking state, and a stop state. When the motor 231 is in an operating state, the motor driving module 122 provides a pulse signal and also provides a driving current; when the motor 231 is in a locked state, in which the motor drive module 122 does not provide a pulse signal, but provides a drive current for locking the rotatable mirror 232 in the current position; when the motor 231 is in a stopped state, the motor driving module 122 does not supply the pulse signal and the driving current. Wherein, when the motor 231 is in the operation state, the motor driving module 122 drives the rotatable mirror 232 so that the rotatable mirror 232 is in the first position; the motor 231 being in a stopped state means that the motor driving module 122 drives the rotatable mirror 232 such that the rotatable mirror 232 is in the second position.
Referring to fig. 6, fig. 6 is a block diagram of a third module of a control system for a time-sharing optical shutter according to an embodiment of the present application. The control system 100 of the time-sharing optical shutter further includes a host computer 140, and the host computer 140 is connected to the system bus 110. The host computer 140 may have a display screen to display status information of each sub-time division shutter 23. The host computer 140 is a device for performing information interaction with each optical shutter module, such as a mobile phone, a tablet, or a computer. Optionally, in the present application, the control module 121 of each time-sharing optical shutter module 120 may be further connected to the system bus 110 through a Serial peripheral interface (Serial PeripheralInterface, SPI) to communicate with the host computer 140 to transmit driving commands.
As described above, each time-sharing optical shutter module 120 has a plurality of light-emitting channels 233 in the corresponding sub-time-sharing optical shutter 23, and each light-emitting channel 233 is an output coupling 2332, and each sub-time-sharing optical shutter 23 further includes a plurality of rotatable mirrors 232, and each rotatable mirror 232 corresponds to one light-emitting channel 233. Each motor drive module 122 is capable of driving a motor 231, each motor 231 being capable of moving a rotatable mirror 232. Wherein, this control module 121 is used for: judging whether the rotatable mirror 232 corresponding to the target channel is at the target position or not through the state information transmitted by the monitoring module 123; if not, controlling the motor driving module 122 to drive the motor 231, wherein the motor 231 drives the rotatable mirror 232 to move so that the rotatable mirror 232 is at the target position; if yes, the motor driving module 122 is controlled to drive the motor 231, and the motor 231 is at the current position, i.e. the motor 231 is in a locked state. It will be appreciated that when the rotatable mirror 232 is in the target position, the light beam is reflected by the rotatable mirror 232 and then emitted from the target channel.
As can be seen from the foregoing, in the embodiment of the present application, the control system 100 of the time-sharing optical shutter may have one or more time-sharing optical shutter modules 120, and each of the time-sharing optical shutter modules 120 has one or more light-emitting channels 233 corresponding to the sub-time-sharing optical shutter 23. Accordingly, depending on the number of light-emitting channels 233, each time-sharing optical shutter module 120 may further be provided with one or more monitoring modules 123 and one or more motor driving modules 122, so as to implement hardware expansion of the control system 100 of the entire time-sharing optical shutter. That is, the user only needs to operate some modules on the program of the two-way time-sharing optical shutter module 120 to distinguish the addresses of the optical shutter modules, and can develop and upgrade the whole series of products without changing any software code, thereby prolonging the life cycle of the system and reducing the material cost and the labor cost.
Referring to fig. 7, fig. 7 is a block diagram of a time-sharing shutter module in the control system of the time-sharing shutter according to the embodiment of the present application. Each of the monitoring modules 123 has at least one sensor 1231, and a plurality of sensors 1231 are used to monitor the state information of the corresponding sub-time division shutter 23, such as to obtain the position information of the corresponding rotatable mirror 232. For example, each monitoring module 123 further includes at least one hall position sensor 1231, and the hall position sensor 1231 is configured to obtain position information of the corresponding rotatable mirror 232. For another example, each monitoring module 123 further includes at least one photoelectric sensor 1231, where the photoelectric sensor 1231 is configured to detect a photoelectric signal of the optical fiber cable for back-end laser processing on the corresponding output coupling 2332, and the photoelectric sensor 1231 transmits the photoelectric signal to the control module 121 to obtain the coupling degree of the optical fiber. The control module 121 can upload the coupling degree of the optical fiber to the upper computer 140 on the system bus 110 at fixed time intervals, so as to prompt the user that one of the light emitting channels 233 of the time-sharing optical shutter 2 is in a usable state.
In some alternative embodiments, referring to fig. 8, fig. 8 is a fourth block diagram of a control system for a time-sharing optical shutter according to an embodiment of the present application. The system bus 110 is also used for acquiring and transmitting configuration information; any one of the plurality of time-division optical gate modules 120 is provided for receiving the configuration information, any one of the time-division optical gate modules 120 is electrically connected to the other time-division optical gate modules 120 through the internal bus 130, and any one of the time-division optical gate modules 120 transmits the configuration information to the other time-division optical gate modules 120 through the internal bus 130.
When the number of the time-sharing optical shutter modules 120 is plural, the time-sharing optical shutter modules 120 are divided into a first time-sharing optical shutter module 124 and at least one second time-sharing optical shutter module 125, and the first time-sharing optical shutter module 124 is used for receiving the configuration information transmitted by the system bus 110. The time-sharing shutter control system 100 further includes an internal bus 130, and the first time-sharing shutter 2 is electrically connected to the second time-sharing shutter module 125 through the internal bus 130 to transmit configuration information. The configuration information may be monitoring protection enabling information, motor parameters and threshold parameters. The internal bus 130 may be a CAN bus, 485 bus, or ethernet.
For example, the first time-sharing optical shutter module 124 includes a first control module 1241, a first motor driving module 1242, and a first monitoring module 1243; the second time-division optical gate module 125 includes a second control module 1251, a second motor drive module 1252, and a second monitor module 1253. When the control system of the sub-time-sharing optical shutter 23 system is powered on and initialized, the first control module 1241 receives the configuration information through the system bus 110, and then the first control module 1241 configures the first motor driving module 1242 and the first monitoring module 1243 according to the configuration information. The first control module 1241 then further transmits the configuration information to all the second control modules 1251 via the internal bus 130, and after each second control module 1251 receives the configuration information, the second control module 1251 configures the second motor driving module 1252 and the second monitoring module 1253 according to the configuration information. It will be appreciated that the system bus 110 transmission pressure can be greatly relieved by the internal bus 130 transmitting configuration information between the first time-division shutter module 124 and the second time-division shutter module 125.
In some alternative embodiments, referring to fig. 9, fig. 9 is a fifth block diagram of a control system for a time-sharing optical shutter according to an embodiment of the present application. The time-sharing shutter control system 100 further includes a memory module 127, the memory module 127 being electrically connected to a time-sharing shutter module 124, the memory module 127 being configured to store configuration information.
For example, after each sub-time division optical shutter 23 control module 121 is powered on and initialized, the first control module 121 and the second control module 121 configure the monitoring protection enable of the corresponding monitoring module 123 and configure the motor parameters of the motor driving module 12 by reading the configuration information from the storage module 127.
For another example, the first time-division optical shutter module 124 receives the configuration information and stores the configuration information in the storage module 127. Each time-division optical shutter module 120 is initialized after the control system 100 of the time-division optical shutter is powered up, only the configuration information in the storage module 127 needs to be read, so as to configure the motor parameters of the motor driving module 12 and the monitor protection enabling in the monitor module 123. Thus, in a subsequent use, the time-sharing optical gate module 120 can directly access the configuration information stored in the storage module 127 after power-up, and the upper computer 140 does not need to send the configuration information to the first time-sharing optical gate module 124 in the subsequent use. It will be appreciated that by providing the memory module 127, configuration information may be saved and re-used, relieving the operating pressure of the time-sharing shutter control system 100. Optionally, the first time-sharing optical shutter module 124 may receive the configuration information of the upper computer 140 through a serial interface.
In some alternative embodiments, each monitoring module 123 includes at least one sensor 1231, the configuration information includes monitoring protection enable information, and each control module 121 is configured to select the target sensor 1231 according to the monitoring protection enable information such that the target sensor 1231 is in the write protection enable state.
Wherein, the monitoring device is further used for monitoring the use condition information of the sub-time division optical shutter 23, and the control module 121 is used for obtaining the state information according to the use condition information; based on the state information, the sub-time division shutter 23 is controlled to close.
The monitoring device is further configured to monitor usage status information of the sub-time-division optical shutter 23, and if the usage status information is abnormal, the sub-time-division optical shutter 23 can be controlled to be closed.
The monitoring device comprises one or more of a temperature sensor, a photoelectric sensor, a water flow meter and a humidity sensor; correspondingly, the use condition information comprises one or more of temperature information, light intensity information, water cooling information and humidity information.
It will be appreciated that in practice, the protection point will be different for different sub-time shutters 23, and the required monitoring function will be different, i.e. corresponding to different sensors 1231. Since each time-sharing optical shutter module 120 has a monitoring module 123, the monitoring module 123 includes a plurality of sensors 1231, so that a target sensor 1231 among the plurality of sensors 1231 can be selected for different protection points, and the target sensor 1231 is placed in the write-protection enabled state, thereby achieving the customization requirement of the entire sub-time-sharing optical shutter 23 system. The monitoring function of the protection point comprises one or more of scattered light monitoring, water flow monitoring, light beam interception monitoring, safety gate monitoring, double-end output optical cable temperature monitoring and FFBD coupling monitoring. For example, the safety gate of the time-sharing optical gate 2 is monitored, one of the time-sharing optical gate modules 120 monitors the safety gate, and the next switching operation of the light-emitting channel 233 can be performed under the condition that the safety gate is completely closed.
The monitoring module 123 is capable of monitoring the state of the corresponding sub-time division shutter 23. The monitoring module 123 includes one or more of a hall position sensor 1231, a temperature switch, a photoelectric sensor 1231, a water flow meter, and a humidity sensor 1231. The temperature control switch, the photoelectric sensor 1231, the water flow meter and the humidity sensor 1231 monitor the light beam cutoff absorption cavity, the coupling degree of the input light beam and the output light beam, the water flow of the output channel and the humidity inside the sub-time division shutter 23 respectively.
For example, the sub-time-division shutter 23 includes a first sub-time-division shutter 23 and a second sub-time-division shutter 23, and the control system 100 of the time-division shutter includes a first time-division shutter module 124 and a second time-division shutter module 125, where the first time-division shutter module 124 corresponds to the first sub-time-division shutter 23 and the second time-division shutter module 125 corresponds to the second sub-time-division shutter 23. If the protection point of the first time-sharing optical shutter module 124 is set to be humidity and the protection point of the second time-sharing optical shutter module 125 is set to be temperature, the humidity sensor 1231 in the monitoring module 123 of the first time-sharing optical shutter module 124 is set to be in a write-protected state, and the temperature sensor 1231 in the monitoring module 123 of the second time-sharing optical shutter module 125 is set to be in a write-protected state according to the configuration information.
Wherein the configuration information further includes a threshold parameter, the control module 121 is further configured to obtain data of the target sensor 1231, compare the data of the target sensor 1231 with the threshold parameter, and obtain the state information of the corresponding sub-time division shutter 23 according to the comparison structure. The form of the threshold parameter is not particularly limited and includes, but is not limited to, values such as maximum, minimum, and standard deviation.
For example, the target sensor 1231 is a temperature sensor 1231, and the temperature sensor 1231 is configured to obtain the temperature of the corresponding sub-time division shutter 23; the threshold parameter of the time-sharing optical shutter module 120 is a preset temperature, and the control module 121 of the time-sharing optical shutter 23 is configured to compare the temperature of the time-sharing optical shutter 23 with the preset temperature. When the temperature of the sub-time-division shutter 23 is greater than the preset temperature, the time-division shutter module 120 displays the status information to determine abnormality. The control module 121 of the sub-time-division shutter 23 may transmit the status information determined to be abnormal to the other time-division shutter modules 120 through the internal bus 130. The control module 121 in the other time-sharing optical shutter module 120 receives the abnormal state information to take corresponding measures, such as controlling the motor driving module 122 and the monitoring module 123 to power off. The control module 121 of the sub-time-sharing optical shutter 23 may transmit the status information determined to be abnormal to the upper computer 140 through the system bus 110, so that the upper computer 140 can provide the status information to the user. When the temperature of the sub-time-division shutter 23 is equal to or less than the preset temperature, the time-division shutter module 120 determines the state information as normal.
In some cases, an alarm module and a laser control module are also connected to the system bus 110. When the state information of the sub-time-division optical shutter 23 is abnormal, the control module 121 of the corresponding sub-time-division optical shutter 23 transmits the state information to the alarm module or the laser control module through the system bus 110, so that the alarm module gives an alarm, reminds the user of timely processing, and enables the laser control module to stop driving the laser.
In some cases, when the threshold parameter is already stored in the storage module 127, the control module 121 of the first time-sharing shutter module 124 reads the threshold parameter from the storage module 127 every time the time-sharing shutter module 120 is powered up, and sends the threshold parameter to the upper computer 140 for presentation via the system bus 110. The user can know the threshold value parameter of each monitoring module 123 through the upper computer 140, and the user can adjust the magnitude of the threshold value parameter according to actual needs.
In some alternative embodiments, the configuration information further includes a plurality of motor parameters, each corresponding to a motor model, and the control module 121 of the time-sharing shutter module 120 is configured to configure the motor parameters for the motor driving module 122 of the time-sharing shutter module 120 according to the motor model.
It will be appreciated that the adjustment of the motor 231 is complex, requiring constant adjustment for different models of motor 231, so a set of parameters is required to drive the motor 231 to work well. In this embodiment, the configuration information may include a motor parameter library, where the motor parameter library includes a plurality of motor parameters, and each model of motor 231 corresponds to one motor parameter, and when the electrode driving module 122 configures the corresponding motor parameter to redrive the motor 231, so that the motor 231 can have a good working state. It will be appreciated that by storing a plurality of motor parameters in the storage module 127 in advance, and then configuring the motor driving module 122 according to the motor model used, the motor 231 is in a good working state in the subsequent use. The user does not need to adjust the motor 231 every time it is used, and the working efficiency is greatly improved.
Optionally, the storage module 127 is provided with motor parameters configured for different types of motors 231; accordingly, after the first time-sharing optical shutter module 124 is powered on and initialized, the control module 121 reads the motor parameter library of the storage module 127, and sends the plurality of motor parameters to the human-computer interface through the system bus 110 for displaying to the user, so that the user can conveniently and directly call according to the model of the motor 231 without setting the parameters each time.
Alternatively, the control module 121 may directly read the corresponding motor parameters according to the hardware dialing of the motor 231 to configure the motor driving module 122.
