Description

Technical Field

[0001] The present invention belongs to the technical field of equipment safety, and in particular relates to an intelligent automatic locking and tagging device and system. Background Art

[0002] Lockout Tag Out (LOTO) has always been an important safety standard for the safe use of equipment. Most manufacturing companies around the world require maintenance personnel to comply with this lockout tagout operation to avoid safety accidents caused by accidental opening of equipment during maintenance, so as to ensure the safety of personnel in the process of repairing equipment. Among them, with the continuous development of industrial intelligence, equipment is gradually moving towards automation and intelligence, and no longer relies entirely on people to operate. This has also led to frequent safety accidents due to failure to perform lockout tagout operations as required. Effective monitoring and management of lockout tagout has always been a top priority for enterprise safety management.

[0003] The existing lockout and tagout implementation method generally adopts a simple mechanical lock and an indicator sign to perform the related operations of locking and tagging the energy switch of the equipment. Among them, the lockout and tagout method of actual lock is very inconvenient to operate, and the lock and key are also very easy to be lost or forgotten, resulting in lax awareness of personnel, and illegal operations such as forgetting to lock and tag out, deliberately not locking and tagging out, and locking and tagging out arbitrarily will often occur. These are one of the reasons for the occurrence of safety accidents in the use of enterprise equipment. Generally, enterprises have the phenomenon of difficult supervision and poor supervision effect. In addition, the lockout and tagout of the energy switch of each device are independent and separate, and it is impossible to realize the linkage lockout and tagout of the energy switches of multiple devices, which also causes inconvenience to personnel operation and cannot effectively ensure the safety of operators.

[0033] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0034] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0035] See also Figures 1 to 3 The present application provides an intelligent automatic locking and tagging device, comprising:

[0036] Control circuit 1, energy switch 2, identity recognition module 3, automatic locking module, alarm module 5, control circuit 1 is respectively connected with energy switch 2, identity recognition module 3, automatic locking module, alarm module 5 by signals;

[0037] In response to the closing signal of the energy switch 2, the control circuit 1 is used to control the alarm module 5 to issue a locking reminder; in response to the identity information collected by the identity recognition module 3, the control circuit 1 is used to upload the identity information to an external platform for verification or to perform local verification on the identity information; in response to the locking and tagging instruction obtained after the identity information verification, the control circuit 1 is used to control the automatic locking module to lock the energy switch 2, and control the alarm module 5 to prompt the locked and tagging status.

[0038] This embodiment is now described in further detail, but is not limited thereto.

[0039] The intelligent automatic lockout and tagout device of this embodiment is applicable to the lockout and tagout of various electrical equipment, and can be very convenient to modify the electrical switches of the original equipment. Figure 2 , it is only necessary to fix the entire device at the switch of the original housing of the equipment, so that it can have the function of intelligent lockout and tagout of this embodiment. Furthermore, this embodiment is more suitable for electrical equipment groups that need to be locked and tagout, that is, the various devices in the electrical equipment group are related to each other, and when locking and tagout are required, multiple devices in the group need to be operated at the same time. Through this embodiment, the mutual association of locking and tagout of multiple devices can be easily realized, which is convenient and efficient to use and has better safety.

[0040] Specifically, the energy switch of the present application can generate a closing signal when closed by electromagnetic induction, or can generate a closing signal when closed by electrical contact, so as to achieve the purpose of switch status detection during the locking and tagging process.

[0041] See also Figure 2 and Figure 3The automatic locking module of this embodiment adopts a servo motor 41 and a locking link, wherein the energy switch 2 of this embodiment is provided with a hole slot, and the servo motor 41 drives and controls the locking link to insert or withdraw from the hole slot to achieve locking and unlocking of the energy switch 2, and the locking link includes a push rod 421, a transmission rod 422, and a latch 423. One end of the push rod 421 is connected to the servo motor 41, and the other end of the push rod 421 is connected to the latch 423 via the transmission rod 422. The transmission rod 422 can be driven by pushing, rotating, levering, etc., so that the latch 423 moves along the direction of the hole slot. In addition to the locking method of inserting the pin 423 into the hole, the automatic locking module can also design the connection relationship between the energy switch 2 and the device lock core to be movable and variable. When locking is required, the automatic locking module separates the lock core from the energy switch 2, that is, the energy switch 2 is disconnected from the lock core, so that the energy switch 2 cannot change the state of the lock core. When unlocking is required, the automatic locking module engages the lock core with the energy switch 2 again, that is, the energy switch 2 and the lock core rotate synchronously, so that the energy switch 2 can change the state of the lock core. Similarly, the automatic locking module can also adopt other structures, such as a lock buckle type, which automatically mechanically locks and locks as it rotates when locking, and is electrically unlocked when unlocking. I will not go into details here.

[0042] Preferably, see Figure 2 and Figure 3 The automatic locking module of this embodiment is also provided with a position sensor 43, which is arranged below the locking link, for detecting the locking state and unlocking state of the locking link, and for limiting the servo motor 41 and the locking link to prevent the servo motor 41 and the locking link from being damaged by over-limit movement. By setting the position sensor 43 in the automatic locking module of this embodiment, not only can the status monitoring feedback be performed, but also the limit protection of the automatic locking module can be performed, thereby reducing mechanical damage and extending the service life.

[0043] See also Figure 3 The identity recognition module 3 of this embodiment includes a fingerprint recognition module and a finger sensor. The finger sensor is used to sense finger input and wake up the fingerprint recognition module. The fingerprint recognition module is used to collect fingerprint information of the lockout operator. The control circuit 1 is used to upload the fingerprint information to the external platform for verification. The finger sensor can be an infrared sensor. The fingerprint recognition module has the characteristics of small data volume and fast transmission. In this embodiment, it can cooperate with the communication method of the narrowband Internet of Things NB-IOT to achieve efficient identity information verification communication, and can meet the simultaneous lockout verification communication requirements of multiple intelligent automatic lockout devices, and will not cause obvious communication delays, and the overall operation is not affected. In addition to the fingerprint recognition module, the identity recognition module 3 of this embodiment can also use modules such as face recognition and identity password input to realize the input of identity information. At the same time, a 5G communication module can also be used to achieve more efficient and fast communication between the device and the platform.

[0044] The control circuit of this embodiment at least includes a controller, a power module, and a NB-IOT communication module or a 5G communication module for communicating with an external platform. The controller is provided with at least a sensing port for an energy switch, a collection port corresponding to an identity recognition module, a drive port corresponding to an automatic locking module, and a control port for an alarm module. Among them, the control circuit of this embodiment does not need to perform complex data processing, but only needs to complete data communication and logic control. The data processing links such as identity information verification are handed over to the external platform. In this way, the overall structure of each device is simple and the operation is efficient, which reduces costs and energy consumption, prolongs the service life, makes information verification safer, and reduces the possibility of device downtime.

[0045] See also Figure 1 The alarm module 5 of this embodiment uses sound and / or light alarm, wherein the light alarm can be indicated by red, yellow, or green. Preferably, red can represent a lockout violation or a lockout reminder, yellow can represent the lockout state, i.e., the automatic locking module locks the energy switch 2, and green can represent the normal opening state of the energy switch 2. In addition, the alarm module 5 with other indication modes can also be used, which will not be repeated here.

[0046] In this embodiment, the identity information of the lockout and tagout is collected by the identity recognition module, and sent to the external platform for verification through the control circuit. After the verification, the automatic locking module is controlled to lock the energy switch to complete the lockout and tagout operation. The operator does not need to carry a real lock or a sign. The identity information is collected by the identity recognition module, and there is no need to carry any objects, such as fingerprints, faces and other features. This makes the lockout and tagout convenient and efficient to use, more humane and intelligent, and solves the problems of inertia and difficult supervision in the lockout and tagout.

[0047] This embodiment is now introduced in conjunction with the lockout and tagout process of the device.

[0048] See also Figure 4 When locking and tagging are required, turn off the energy switch. When receiving the closing signal of the energy switch, the control circuit controls the alarm module to issue a locking reminder to remind the operator to lock and tag.

[0049] See also Figure 4When the operator inputs his identity information, such as fingerprint, through the identity recognition module, the control circuit uploads the identity information to the external platform or verifies the identity information locally. The platform verifies whether the current identity information has the authority to perform the lock and tag operation by retrieving the pre-configured authorization information. The control circuit verifies locally whether the identity information has the authority to perform the lock and tag operation according to the authorization information configured by the external platform, and feeds back the verification information to the cloud platform. If there is no authority, the platform sends or the control circuit directly generates a verification failure instruction, and the alarm module maintains the lock reminder. If there is authority, the platform sends or the control circuit directly generates a lock and tag instruction, so that the control circuit controls the automatic locking module to lock the energy switch, and adjusts the alarm module to prompt that the current state is locked and tagged, which has warned others that someone is working.

[0050] When the operator completes the work and needs to restore the equipment status, he can input his identity information through the identity recognition module again. The control circuit will upload the identity information to the external platform or verify the identity information locally. Preferably, the platform or control circuit not only checks whether the current identity information has the authority to perform the locking and tagging operation, but also checks whether the current identity information is the same as the information at the previous locking and tagging. If it is authorized and the information is the same, the platform sends or the control circuit directly generates an unlocking instruction, otherwise the verification fails. The control circuit controls the automatic locking module to unlock the energy switch again according to the unlocking instruction, and then the energy switch can be turned on. In this way, it can avoid unlocking by others when different operators have the authority, which can fully ensure the safety of the operators and greatly improve the security of the system.

[0051] The present application also provides an intelligent automatic locking and tagging system based on the above-mentioned embodiments, including a cloud platform and an intelligent automatic locking and tagging device as described in any one of the above-mentioned embodiments; the cloud platform communicates with the intelligent automatic locking and tagging device to verify the identity information uploaded by the intelligent automatic locking and tagging, and to monitor the locking and tagging process.

[0052] In one implementation of this embodiment, the cloud platform communicates with multiple intelligent automatic locking and tagging devices separately, and is used for the stand-alone locking and tagging of each intelligent automatic locking and tagging device respectively, without affecting each other. In another implementation of this embodiment, the cloud platform communicates with multiple intelligent automatic locking and tagging devices in a network, and is used for the linkage locking and tagging between multiple intelligent automatic locking and tagging devices, which are related to each other and are not independent of each other, that is, they are locked and unlocked in linkage with each other.

[0053] Preferably, the cloud platform is also used for personnel authorization management for lockout and tagout, and work order creation and management for lockout and tagout operations. Personnel authorization management can add or delete personnel's lockout and tagout permissions and unlocking permissions, and work order creation and management for lockout and tagout operations can control the intelligent automatic lockout and tagout devices that need to be locked out on the cloud platform, and can realize the mutual association between multiple devices to perform linked lockout and tagout operations.

[0054] Preferably, the present embodiment further includes a device terminal for accessing the cloud platform to monitor the lockout and tagout process information in real time. The cloud platform can receive the information uploaded by the intelligent automatic lockout and tagout device and store and manage it. Specifically, it can be processed into a chart for easy monitoring, and can analyze personnel, lockout and tagout time, downtime, and provide big data management layer analysis, etc. Device terminals such as mobile phones, tablets, PCs, etc. can access the cloud platform to monitor the lockout and tagout process throughout the process, and view the information of each lockout and tagout operation in history, as well as the information of each lockout and tagout operation currently executed. Through the cloud platform and the device terminal, the present embodiment can realize all-round monitoring and sharing from the device end to the management platform and then to the operator, so that comprehensive personnel can effectively understand the current situation of the lockout and tagout of the equipment in real time, which can not only prevent some equipment personnel who can remotely control the equipment from operating illegally, but also effectively, conveniently and timely view the lockout and tagout situation when the operator is at a certain distance from the energy switch, so as to improve the safety of the equipment operation.

[0055] This embodiment is now introduced in conjunction with the linked lockout and tagout process of the device.

[0056] See also Figure 5 When a linked lockout and tagout is required, turn off the energy switches A, B, and C. When receiving the shutdown signal of the energy switches A, B, and C, the control circuit controls the alarm modules A, B, and C to issue a lockout reminder to remind the operator to lock out and tagout.

[0057] See also Figure 5When different or the same operators input their identity information A, B, C, such as fingerprints, through the identity recognition modules A, B, C, the control circuit uploads the identity information A, B, C to the cloud platform or performs local verification on the identity information A, B, C respectively, wherein the platform verifies whether the current identity information A, B, C has the authority to perform the lock-out operation by retrieving the pre-configured authorization information, and the local verification verifies whether the identity information A, B, C has the authority to perform the lock-out operation according to the authorization information configured by the cloud platform, and feeds back the verification information to the cloud platform, and the cloud platform sends an instruction based on the verification information obtained or fed back by its own verification, if there is no authority, a verification failure instruction is sent, and the alarm modules A, B, C maintain the lock reminder, if there is authority, a lock-out instruction is sent so that the control circuit controls their respective automatic locking modules to lock the energy switches A, B, C, and adjusts the alarm modules A, B, C to prompt that the current state is locked and tagged out, and has warned others that someone is working.

[0058] See also Figure 6 When the operator completes the work and needs to restore the equipment status, he can input his identity information A, B, C through the identity recognition module A, B, C again, and the control circuit will upload the identity information A, B, C to the cloud platform again or locally verify the identity information A, B, C respectively. Preferably, the platform or the control circuit not only checks whether the current identity information A, B, C has the authority to perform the lock and tag operation, but also checks whether the current identity information A, B, C is the same as the information at the time of the previous lock and tag operation. If it is authorized and the information is the same, the cloud platform sends an unlocking instruction, otherwise the verification failure instruction is sent. After the control circuit receives the unlocking instruction, it controls the automatic locking module to unlock the energy switches A, B, C again, and the energy switches A, B, C can be turned on. In this way, it can avoid unlocking by others when different operators have the authority, which can fully ensure the safety of the operators and greatly improve the security of the system.

[0059] This embodiment combines an intelligent automatic lockout and tagout device with a cloud platform. The cloud platform can not only uniformly verify the identity information of multiple devices and monitor the lockout and tagout process to achieve separate lockout and tagout for each device, but also multiple devices can be networked together through the same external platform, thereby achieving linkage lockout and tagout of multiple lockout and tagout devices, that is, linkage locking and unlocking, to meet the lockout and tagout requirements of any equipment group, greatly improving the application scope of the device, and the security of the linkage lockout and tagout is more reliable, and there will be no danger caused by the unlocking of a certain device alone, which greatly improves the safety of the operator. In addition, the cloud platform can also perform personnel authorization management, work order establishment and management for lockout and tagout, which is more convenient for enterprise supervision. For operators, it avoids dangerous behaviors of not locking and tagging out due to the operator's laziness, and is more convenient, efficient and safe to use.
