[0002] During the production process at manufacturing enterprises, maintenance personnel often need to enter confined spaces to carry out work activities, which are considered confined space operations.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] The following combination Figure 1-Figure 5 The present invention describes the Internet of Things-based limited space access control, device and electronic equipment thereof.

[0024] Figure 1 The figure is a flow chart of a method for controlling access to a confined space based on the Internet of Things provided by the present invention. The method is applied to a business management system, wherein the business management system is electrically connected to a motion detection device. The electrical connection can be a line connection or a communication connection.

[0025] The movement detection device is arranged on the isolation device at the entrance of the confined space, and is used to obtain movement data of the isolation device when the isolation device moves, and upload the movement data to a data storage location in real time.

[0026] The business management system is a system used at least to monitor whether maintenance personnel enter the confined space to carry out work activities, and to issue an alarm when maintenance personnel illegally enter the confined space to carry out work activities.

[0027] A confined space entrance is an opening that allows maintenance personnel to enter a confined space. A confined space is an enclosed or partially enclosed space that harbors potential hazards, such as oxygen deprivation and the accumulation of toxic gases. Isolation devices at confined space entrances are a safety measure to prevent unauthorized personnel from entering the confined space. Examples of such devices include locks, covers, doors, and other barriers at the confined space entrance.

[0028] The movement detection device, also known as an abnormal movement detection device, is used to detect whether the isolation device at the confined space entrance has moved. For example, the movement detection device can be a sensor mounted on the isolation device at the confined space entrance, or a detection system mounted on the isolation device at the confined space entrance. For example, the movement detection device can be a detection system consisting of a laser transmitter and a laser receiver. When the isolation device blocks the confined space entrance, the laser receiver can receive the laser light emitted by the laser transmitter. When the isolation device is open, revealing the confined space entrance, the laser receiver cannot receive the laser light emitted by the laser transmitter, thereby enabling real-time detection of whether the isolation device at the confined space entrance has moved.

[0029] The movement data is data indicating whether the isolation device at the confined space entrance has moved.

[0030] like Figure 1 As shown in the figure, the limited space access control method based on the Internet of Things includes: Step 101: Send a data acquisition instruction to the data storage location, where the data acquisition instruction is used to acquire the mobile data.

[0031] The data storage location may be a storage location in the business management system or a storage location independent of the business management system.

[0032] In the case where the data storage location is a storage location independent of the business management system, illustratively, the data storage location is a cloud platform, the business management system is electrically connected to the cloud platform, and the cloud platform is electrically connected to the movement detection device; Acquiring the movement data of the isolation device and uploading it to a data storage location in real time may specifically include: acquiring the movement data of the isolation device and uploading it to the cloud platform in real time; Sending the data acquisition instruction to the data storage location may specifically include: sending the data acquisition instruction to the cloud platform.

[0033] For example, the motion detection device can upload the acquired motion data to the cloud platform via the operator's public network. The operator can be China Mobile, China Unicom, etc. The service management system can send data acquisition instructions to the cloud platform through the interface provided by the cloud platform and receive the motion data returned by the cloud platform.

[0034] In this embodiment, by setting the data storage location to a cloud platform independent of the business management system, the data storage location and the business management system can be isolated, so that mobile data will not be written directly to the business management system, which can reduce the impact of the process of writing mobile data on the business management system and enhance the security of the business management system; at the same time, in the event of a failure in the data storage location, the cloud platform where the mobile detection device stores mobile data can be replaced, and the business management system can be adjusted to obtain mobile data from the corresponding cloud platform to normally manage and control access to confined spaces, thereby enhancing the reliability of managing and controlling access to confined spaces.

[0035] Step 102: When the movement data is obtained, determine whether the isolation device moves abnormally based on the movement data.

[0036] It is understood that movement data can only be retrieved from the data storage location if the isolation device at the confined space entrance moves and the movement detection device uploads the movement data to the data storage location. In other words, if the isolation device at the confined space entrance does not move, sending a data retrieval instruction to the data storage location will not retrieve movement data from the data storage location.

[0037] Step 103: When it is determined based on the movement data that the isolation device moves abnormally, an alarm is issued.

[0038] The Internet of Things-based confined space access control method provided by an embodiment of the present invention obtains movement data in the data storage location by sending a data acquisition instruction to the data storage location. The movement data in the data storage location is uploaded in real time when a movement detection device determines that the isolation device at the entrance to the confined space has moved. Therefore, by obtaining the movement data in the data storage location, it is determined whether the isolation device has moved abnormally, and an alarm is issued in the event of abnormal movement of the isolation device, the real-time nature of the alarm can be improved. Based on the alarm, the entry into the confined space can be controlled, thereby improving the real-time nature of the control of the entry into the confined space.

[0039] Based on any of the above embodiments, sending the data acquisition instruction to the data storage location specifically includes: sending the data acquisition instruction to the data storage location at intervals of a preset time length.

[0040] The preset interval time may be 3-7 minutes. For example, the preset interval time may be 5 minutes. On this basis, it can be said that the data acquisition instruction is sent to the data storage location at a frequency of once every 5 minutes to acquire the mobile data in the data storage location.

[0041] Compared with obtaining mobile data from the data storage location in real time, in this embodiment, by uploading mobile data to the data storage location in real time and periodically obtaining mobile data from the data storage location, it is possible to improve the real-time control of entry into confined spaces while reducing the number of times data acquisition instructions are sent and reducing the computing resources occupied by the business management system.

[0042] Based on the above embodiment, the business management system includes a work application permission center; the mobile data includes the limited space identification; Determining whether the isolation device moves abnormally based on the movement data includes: Based on the confined space identifier in the mobile data, querying the confined space operation ticket at the operation application and permission center; wherein the confined space operation ticket includes a standard confined space identifier; If the confined space identifier fails to match the standard confined space identifier and the work ticket for the confined space is not obtained, it is determined that the movement of the isolation device is abnormal.

[0043] The Work Permit Center is a module within the business management system responsible for approving work ticket applications and centrally managing them. For example, if maintenance personnel need to enter a confined space to perform confined space work, they submit a work ticket application to the Center. Once approved by the Center, the work ticket is stored there. Maintenance personnel can then enter the confined space and perform the work according to the work permit process outlined in the ticket.

[0044] The limited space identifier in the movement data is used to identify the limited space corresponding to the movement data. The limited space identifier corresponds one-to-one with the limited space. For example, the limited space identifier can be a limited space number or the location coordinates of the limited space. If the limited space identifier is a limited space number, it is understood that the limited space number is a pre-assigned number for each limited space, and the corresponding limited space can be uniquely identified based on the limited space number.

[0045] The standard confined space identifier in a work ticket is used to identify the confined space corresponding to the work ticket. It should be understood that the standard confined space identifier corresponds to the confined space identifier. For example, if the confined space identifier is a confined space number, the standard confined space identifier is also the confined space number. If the confined space identifier is a location coordinate, the standard confined space identifier is also the location coordinate.

[0046] For example, the confined space identifier in the movement data can be used as a keyword to query the work application permit center. If there is no standard confined space identifier that can match the confined space identifier in the query result, it means that the confined space identifier fails to match the standard confined space identifier, there is no work ticket for the confined space corresponding to the movement data in the work application permit center, and the movement of the isolation device at the entrance of the confined space is abnormal.

[0047] Movement of the isolation device at the confined space entrance generally indicates that the isolation device is open, revealing the confined space entrance. Maintenance personnel enter the confined space to perform confined space operations, thereby determining that the corresponding confined space is abnormal. This can provide timely alarms to confirm the on-site conditions of the confined space and reduce possible operational risks.

[0048] In this embodiment, while the mobile data of the confined space entrance isolation device is stored in the data storage location to form relevant records, the confined space identifier in the mobile data can be obtained, and a query is performed at the operation application permit center based on the confined space identifier. If the query result is that the confined space identifier fails to match the standard confined space identifier and the confined space operation ticket is not obtained, the movement abnormality of the isolation device can be quickly identified and an alarm can be issued in time to reduce possible operation risks.

[0049] When the work application permit center successfully queries the confined space work ticket corresponding to the mobile data, generally speaking, maintenance personnel entering the confined space to perform confined space operations are normal work entry events, but there are also special cases.

[0050] Based on any of the above embodiments, the movement data includes the movement time of the isolation device; After the work application and permission center queries the work ticket for the confined space, the method further includes: If the limited space identifier is successfully matched with the standard limited space identifier and a work ticket for the limited space is obtained, the work application time range in the work ticket is obtained; When the movement time does not fall within the operation application time range, it is determined that the movement of the isolation device is abnormal.

[0051] Exemplarily, the movement detection device may set a timer, obtain the time in the timer as the movement time of the isolation device when the isolation device moves, and add the movement time to the movement data, and upload it to the data storage location in real time.

[0052] The work application time range is the time period specified in the work ticket during which confined space operations are permitted. For example, when a maintenance worker submits a work application to the work permitting center, the work application time range is specified in the work application. After the work application is approved by the work permitting center, the maintenance worker's confined space operations within the work application time range constitute a normal work entry event. For example, if the movement of an isolation device occurs before the start of the work application time range, it can be determined that the movement of the isolation device is abnormal, and it can be determined that the maintenance worker did not perform confined space operations within the work application time range.

[0053] In this embodiment, when the work application permit center successfully queries the confined space work ticket corresponding to the movement data, it further determines whether the movement of the isolation device is abnormal based on whether the movement time of the isolation device is within the work application time range in the work ticket. This can more accurately identify abnormal movement of the isolation device and issue an alarm in time to reduce possible work risks.

[0054] If the abnormal movement of the isolation device is caused by a failure to match the confined space identifier with the standard confined space identifier and a confined space operation ticket is not obtained, based on any of the above embodiments, issuing an alarm includes: Generate an alarm event and push the alarm event to the person in charge of the confined space; A work ticket application supplementally submitted to the work application permission center is received, wherein the work ticket application is a supplementally submitted application when the confined space work in the confined space site is stopped.

[0055] A confined space territorial manager is the person responsible for managing confined spaces in a specific area. A confined space territorial manager can be responsible for one confined space or multiple confined spaces. For example, a confined space territorial manager could be responsible for multiple adjacent confined spaces. The specific number of confined spaces a person is responsible for can be determined based on actual needs and is not further specified here.

[0056] For example, an abnormal operation entry event can be generated and pushed to the person in charge of the confined space. The abnormal operation entry event can include the confined space identifier, allowing the confined space person to conduct on-site inspections of the confined space. For example, if maintenance personnel enter the confined space to conduct confined space operations, the confined space operations can be stopped.

[0057] Potential hazardous factors in confined spaces may change. For example, temperature and humidity may cause changes in the gas composition and concentration in the confined space. Cleaning operations in confined spaces may disturb deposited harmful substances.

[0058] In this embodiment, by submitting a supplementary work ticket application, it is possible to evaluate the potential hazardous factors in the confined space where the confined space operation is to be carried out, determine measures to eliminate or control the potential hazardous factors, and improve the safety of entering the confined space. At the same time, the detailed information of the operation is recorded in the work ticket, and it can be identified whether the work ticket is a supplementary work ticket application, which is convenient for subsequent auditing and tracking, thereby facilitating the access control of confined spaces.

[0059] If the abnormal movement of the isolation device is caused by a successful match between the confined space identifier and the standard confined space identifier, and a confined space operation ticket is obtained, but the movement time does not fall within the operation application time range, based on any of the above embodiments, issuing an alarm includes: Generate an alarm event and push the alarm event to the person in charge of the confined space; Receive a work ticket application resubmitted to the work application permission center; the work ticket application is an application resubmitted after the work application time range is revised.

[0060] For example, in one embodiment, when a work ticket application is resubmitted, confined space operations at the confined space site need to be stopped. After the resubmitted work ticket application is reviewed and approved, the confined space is entered according to the work application time range in the work ticket to carry out the confined space operation.

[0061] In this embodiment, when it is determined that the work ticket application is a resubmission of the work ticket application, the work application time range of the confined space where the confined space operation is to be carried out can be determined based on the work ticket in the work application permit center. In this way, by evaluating the potential risk factors of the confined space where the confined space operation is to be carried out during the moving time and the difference between the potential risk factors within the work application time range, supplementary measures to eliminate or control potential risk factors can be determined more quickly, thereby improving the safety of entering the confined space and speeding up the review speed of the work application permit center.

[0062] As mentioned above, the detailed information of the operation is recorded in the operation ticket, which can identify whether the operation ticket is a resubmitted operation ticket application, which is convenient for subsequent audit and tracking, thereby facilitating the access control of confined spaces.

[0063] The method for supplementary submission and resubmission of work ticket application is basically the same as the method for submitting work ticket application mentioned above, so it will not be repeated here.

[0064] For example, corresponding tags can be added to the job ticket to identify the job ticket, such as the pre-job approval job ticket, the post-job supplementary approval job ticket, the post-job re-approval job ticket, etc.

[0065] Abnormal movement of the isolation device generally means that the isolation device is open, revealing the entrance to the confined space, and the maintenance personnel have not submitted a work ticket application or have not entered the confined space to perform confined space operations within the work application time range of the work ticket. However, there are also unexpected situations, such as an alarm event caused by a malfunction of the movement detection device, which leads to a misjudgment of the isolation device status. In this embodiment, an alarm event is still generated in an unexpected situation, and the alarm event is pushed to the person in charge of the confined space. If no confined space operations are performed on site in the confined space, the alarm event is closed. In this way, the confirmation of the on-site situation of the confined space can be strengthened, and the risk of entering the confined space can be further reduced.

[0066] The IoT-based confined space access control method provided in this embodiment configures a mobile detection device on the isolation device at the entrance of the confined space, obtains the detection results of the mobile detection device from the business management system based on the IoT detection technology, and generates a corresponding event by judging whether the detection result is normal and pushes it to the person in charge of the confined space. Strict qualification and process control are carried out on personnel entering the confined space, thereby improving the standardization and safety of confined space operations.

[0067] In order to specifically illustrate the functions of the limited space access control method based on the Internet of Things provided by this implementation, a specific example is provided below.

[0068] Figure 2 This is one of the system framework diagrams of the limited space access control method based on the Internet of Things provided by the present invention. The limited space access control method based on the Internet of Things is applied to business management systems, such as Figure 2 As shown, the motion detection device is arranged on the isolation device at the entrance of the confined space, and is used to obtain the movement data of the isolation device and upload it to the cloud platform in real time by communication transmission when the isolation device moves; the business management system sends data acquisition instructions to the cloud platform by communication transmission at every preset time interval, and the data acquisition instructions are used to obtain movement data.

[0069] When the business management system obtains movement data from the cloud platform via communication, it determines whether the isolation device has abnormal movement based on the movement data. If the movement data determines that the isolation device has abnormal movement, the abnormal entry event is pushed to the person in charge of the confined space so that the person in charge can confirm the situation on site. If the movement data determines that the isolation device is moving normally, the normal entry event is pushed to the person in charge of the confined space.

[0070] Figure 3This is the second system framework diagram of the limited space access control method based on the Internet of Things provided by the present invention. Figure 3 As shown, the business management system includes an operation application and permission center, which can query the operation ticket of the confined space in the operation application and permission center based on the confined space identifier in the mobile data to push the entry event to the person in charge of the confined space.

[0071] There are two situations in which abnormal entry events are pushed to the person in charge of the confined space: One is to determine that the movement of the isolation device is abnormal when the confined space identification fails to match the standard confined space identification and the confined space operation ticket is not obtained; generate an abnormal entry event, and push the abnormal entry event to the person in charge of the confined space.

[0072] The other is that when the confined space identification is successfully matched with the standard confined space identification and the confined space operation ticket is obtained, the operation application time range in the operation ticket is obtained; when the movement time does not fall within the operation application time range, the movement of the isolation device is determined to be abnormal; an abnormal entry event is generated, and the abnormal entry event is pushed to the person in charge of the confined space.

[0073] Upon receiving an abnormal entry event, the person in charge of the confined space must verify the situation on-site. If someone enters the confined space, they must immediately stop the person and assist maintenance personnel in submitting a supplemental or resubmitting a work permit to the work permit application center. If no one enters the confined space, confirm that the cause is other than the cause and close the abnormal entry event.

[0074] The situation in which a normal entry event is pushed to the person in charge of the confined space is that when the confined space identification successfully matches the standard confined space identification and the movement time falls within the operation application time range, it is determined that the movement of the isolation device is normal; a normal entry event is generated and pushed to the person in charge of the confined space.

[0075] It is understandable that after receiving a normal entry incident, the person in charge of the confined space does not carry out subsequent procedures such as confirming the on-site conditions of the confined space.

[0076] The following describes the limited space access control device based on the Internet of Things provided by the present invention. The limited space access control device based on the Internet of Things described below and the limited space access control method based on the Internet of Things described above can refer to each other.
