Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.
[0032] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.
[0033] Safety control in production workshops typically employs an operational logic of sensor monitoring, data processing, early warning and response, automated control, and data analysis. This enables real-time monitoring of the workshop environment and the status of operating equipment, effectively preventing and handling safety incidents.
[0034] Generally speaking, the operating equipment in the production workshop uses safety relays as safety control loops. That is, the safety relays are used as control lines to control the operating components on the operating equipment based on the detection signals detected by the detection device. This mode can effectively achieve safety control of the operating equipment.
[0035] In some operating equipment that requires hierarchical control, for example, when an emergency stop signal is detected, the entire operating equipment needs to be stopped, which is usually a level 1 control; when a feeding signal is detected, only the transmission line of the operating equipment needs to be stopped, which is usually a level 2 or 3 control. In other words, we can understand that level 1 control requires controlling the entire operating equipment, while level 2 control only requires controlling the designated operating components.
[0036] This hierarchical control mode can precisely control the specific operating components of the equipment without interfering with normal production in the workshop, effectively reducing production safety accidents.
[0037] However, implementing such control logic in safety relays requires connecting numerous circuits in series to achieve hierarchical control. This complex configuration process presents challenges for administrators during installation, and also makes troubleshooting when safety relays malfunction equally complicated.
[0038] Based on this, a specific embodiment of a security management device disclosed herein is introduced, see [link to relevant documentation]. Figure 1 and Figure 2 Safety management equipment 1 is applied to operating equipment 2.
[0039] Specifically, the safety management device 1 includes at least one detection device 11 and a control device 12. The control device 12 is electrically connected to each of the at least one detection device 11 and the operating device 2.
[0040] The control device 12 in this embodiment includes, but is not limited to, microcontrollers, industrial computers, programmable logic controllers, distributed control systems, etc., preferably programmable logic controllers (PLCs), but can be selected according to actual conditions.
[0041] Operating equipment 2 is set up in the production workshop. The operating equipment can be a specific production equipment in the workshop, or it can be a combination of multiple operating components, or it can be an integration of multiple production equipment. The specific setup can be determined according to the actual situation.
[0042] The type and / or quantity of the detection device 11 can also be set according to the specific detection needs. For example, the detection device 11 may include an emergency stop signal detection device, a door lock signal detection device, a feeding signal detection device, etc., but it is not limited to this. The specific device can be selected according to the actual situation.
[0043] For example, an emergency stop signal detection device can be used to detect emergency stop signals, a door lock signal detection device can be used to detect door lock opening signals, and a loading signal detection device can be used to detect loading signals. The control device 12 can determine whether to control the corresponding operating components of the operating equipment 2 based on the received signals and send action commands to them.
[0044] See Figure 3 To understand the hierarchical control principle of safety management equipment, the following is a detailed explanation:
[0045] At least two of the at least one detection device 11 include a first detection device 111 and a second detection device 112. The first detection device 111 is used to acquire a first detection signal of the operating equipment 2, and the second detection device 112 is used to acquire a second detection signal of the operating equipment 2.
[0046] Typically, the response priority of the first detection signal is higher than that of the second detection signal. When the control device 12 receives both the first and second detection signals simultaneously, it will respond to the first detection signal first. The control device 12 will only respond to the second detection signal if it does not receive the first detection signal. Specifically:
[0047] The control device 12 is used to send a first action command to the first operating component 21 and the second operating component 22 of the operating device 2 under a first preset condition, the first preset condition including receiving a first detection signal.
[0048] Since the first action command matches the first detection signal, the response priority of the operating device 2 to the first action command can be set to the highest priority. When the operating device 2 receives the first action command, it will control all operating components of the operating device 2 to respond.
[0049] The control device 12 is used to send a second action command to the second operating component 22 under a second preset condition, the second preset condition including receiving a second detection signal and not receiving a first detection signal.
[0050] Since the second action command matches the second detection signal, the response priority of the operating device 2 to the second action command can be set to the second highest priority. The operating device 2 will only control the second operating component 22 to respond when it receives the second action command without receiving the first action command.
[0051] In this embodiment, the first detection device 111 and the second detection device 112 are connected through the control device 12, and the operating components of the operating equipment are directly controlled based on the control device 12. The original hierarchical control logic is directly integrated into the control device, simplifying the setup process for safety management in the production workshop by eliminating the need to build different circuits for different levels. When new levels and loops need to be added, only the control device 12 needs to be configured, reducing the workload of setup.
[0052] See Figure 4 Based on the hierarchical control principle provided in this embodiment, the hierarchical control of safety management equipment can be further extended, specifically:
[0053] At least three of the detection devices in at least one detection device 11 include a first detection device 111, a second detection device 112, and a third detection device 113. The third detection device 113 is used to acquire a third detection signal from the operating equipment 2;
[0054] The control logic for the first detection device 111 and the second detection device 112 can be referred to in the previous embodiment, and will not be repeated here. Based on this, the third operating component must also respond to the first action command with the highest priority.
[0055] Therefore, the control device 12 is used to send a first action command to the first operating component 21, the second operating component 22 and the third operating component 23 of the operating device 2 under the first preset conditions.
[0056] The control device 12 is used to send a third action command to the third operating component under a third preset condition, the third preset condition including receiving a third detection signal and not receiving a first detection signal and a second detection signal.
[0057] Since the third action command matches the third detection signal, the response priority of the operating device 2 to the third action command can be set to the third highest priority. The operating device 2 will only control the third operating component 23 to respond when it receives the third action command without receiving the first action command or the second action command.
[0058] The control logic of the safety management device will be further explained through a specific implementation method:
[0059] The first detection device 111 includes an emergency stop signal detection device, which in this embodiment can be an emergency stop button, installed at multiple locations in the production workshop. The first detection signal includes an emergency stop signal, and the first action command includes an emergency stop command. When a manager or production worker presses the emergency stop button, the control device 12 receives the emergency stop signal, generates an emergency stop command, and sends it to the operating equipment 2 to control all operating components of the operating equipment 2 to stop urgently.
[0060] The second detection device 112 includes a feeding signal detection device, which in this embodiment can be a feeding light curtain, set in the feeding area of the transport component. The second detection signal includes a feeding signal, the second operating component 22 includes a transport component, and the second action command includes a stop transport command. In the absence of an emergency stop signal, when feeding occurs in the production workshop, the beam of the feeding light curtain is interrupted. The control device 12 receives the feeding signal, generates a stop transport command, and sends it to the operating equipment 2 to control the transport component to stop transport, facilitating feeding in the workshop.
[0061] The third detection device 113 includes a door lock signal detection device, which in this embodiment can be a door lock sensor, located in the door lock area of the punch press assembly. The third detection signal includes a door lock opening signal. The third operating component 23 includes the punch press assembly, and the third action command includes a stop punch press operation command. When the door lock of the punch press assembly is opened without receiving an emergency stop signal or a loading signal, the door lock signal detection device generates a door lock opening signal. The control device 12 receives the door lock opening signal, generates a stop punch press operation command, and sends it to the operating device 2 to control the punch press assembly to stop operating.
[0062] This setup allows for the rapid identification of unresponsive devices or components when problems arise with the safety management equipment or its operating components, facilitating maintenance by staff and improving the stability of the safety management equipment.
[0063] In one embodiment, the operating device 2 is also equipped with a status feedback device. The status feedback device may be a microcontroller, computer, digital signal processor, embedded processor, etc.
[0064] The status feedback device is used to monitor the working process of each operating component in the operating equipment 2 in real time. At the same time, the control device 12 is electrically connected to the status feedback device of the operating equipment 2, and the status feedback device is used to provide feedback on the operating status of the operating equipment 2 to the control device 12.
[0065] After receiving the operating status of the operating device 2, the control device 12 can refer to the operating status of the operating device 2 to a certain extent when generating the corresponding action command.
[0066] Specifically, the first preset condition includes receiving a first detection signal and the operating state being a first operating state; or, the second preset condition includes receiving a second detection signal, not receiving a first detection signal, and the operating state being a second operating state.
[0067] The first or second operating state can be set according to the actual usage scenario.
[0068] Taking the second operating component 22 as a transportation component as an example, the second operating state can be set to a state where no material is being transported on the transportation component. If the status feedback device reports that there is material being transported on the transportation component, even if the control device 12 receives the second detection signal but does not receive the first detection signal, the transportation component will not stop operating until the status feedback device reports that there is no material being transported on the transportation component.
[0069] In one embodiment, the security management device can also be remotely controlled by administrators. Specifically, the control device 12 is communicatively connected to an external terminal device, and the control device is used to receive action commands sent by the terminal device. The communication connection method includes wired connection, wireless connection, wide area network connection, etc., and the specific method is selected according to the actual scenario.
[0070] When the control device 12 receives an action command from the terminal device, it can directly send it to the operating device 2, or it can determine whether to send it to the operating device 2 based on the corresponding detection device. For example, if the control device 12 receives an emergency stop command from the terminal device, it can directly send the emergency stop command to the operating device 2 to control all operating components of the operating device 2 to stop operating. If the control device 12 receives a stop transport command from the terminal device, but the control device 12 has not received a loading signal detected by the loading signal detection device, it may not send the stop transport command to the operating device 2.
[0071] In one embodiment, the wiring of the safety management device uses components that meet EN ISO 13849-1 (safety design life) and IEC 61508 (safety level).
[0072] This disclosure also provides a workshop production system, see [link to relevant documentation]. Figure 5 The workshop production system includes operating equipment 1 and safety management equipment 2 in the above embodiments.
[0073] The safety management equipment 1 includes at least one detection device 11 and a control device 12. The control device 12 is electrically connected to each of the at least one detection device 11 and the operating equipment 2.
[0074] Operating equipment 2 is set up in the production workshop. The operating equipment can be a specific production equipment in the workshop, or it can be a combination of multiple operating components, or it can be an integration of multiple production equipment. The specific setup can be determined according to the actual situation.
[0075] The workshop production system obtained based on this embodiment is developing towards a more intelligent, precise, and efficient direction, providing a strong guarantee for safe production in the workshop.
[0076] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.
