[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Below, in conjunction with the accompanying drawings, a confined space control method, device, electronic device and storage medium provided by the embodiments of the present application are described in detail through specific embodiments and their application scenarios.

[0022] Figure 1A method for controlling a confined space provided by an embodiment of the present invention is shown. The method can be executed by an electronic device, such as a terminal device. That is, the method can be executed by hardware or software installed in the terminal device. The method includes the following steps:

[0023] Step S101: In response to a first operation of an operator to open an access passage to a confined space, first image information of a first tool carried by the operator is acquired, and the access passage to the confined space is opened to allow the operator to enter the confined space.

[0024] Specifically, the staff in the confined space are divided into managers and operators. The managers manage the tools and operators in the confined space. The first operation is for the operators to open the entry and exit channels of the confined space before entering the confined space. After the operators click the opening button of the entry and exit channels of the confined space, the entry and exit channels of the confined space are opened.

[0025] Before a worker enters a confined space, a camera installed at the entrance to the confined space can capture first image information of a first tool carried by the worker. The first tool is the tool carried by the worker before entering the confined space, such as protective equipment (e.g., a gas mask), a leakage protector, an oxygen respirator, and firefighting equipment. The first image information includes, but is not limited to, an image of the first tool's appearance and text information. The camera can be a video camera, a panoramic camera, etc. When the camera captures the image, it can provide a voice prompt to the worker to place the first tool in a suitable position for easy capture. After the camera captures the first tool and outputs the image information, it is stored.

[0026] Step S103: In response to the operator's second operation of opening the access passage to the confined space, second image information of a second tool carried by the operator is acquired.

[0027] Specifically, after the operator enters the confined space and completes the confined space work, the operator needs to leave the confined space. The second operation is to open the entry and exit channel of the confined space before the operator exits the confined space. After the operator clicks the opening button of the entry and exit channel of the confined space, the camera device is triggered to take pictures. If the camera device cannot capture the image of the second tool, a prompt message is issued to prompt the operator to place the second tool within the camera range of the camera device and then take an image of the second tool.

[0028] The second tool is the tool carried by the operator after entering the confined space and before exiting the confined space, such as protective equipment (such as a gas mask), leakage protector, oxygen respirator and fire-fighting equipment, etc. The second tool can be the same as or different from the first tool.

[0029] Step S105: Match the first image information with the second image information. If the first image information and the second image information match, open the entrance and exit channel of the confined space to allow the operator to exit the confined space. If the first image information and the second image information do not match, close the entrance and exit channel of the confined space and issue an alarm message.

[0030] Specifically, if the first tool and the second tool carried by the operator before entering and exiting the confined space are the same, the first image information and the second image information collected by the camera device are matched; if the first tool and the second tool carried by the operator before entering and exiting the confined space are different, the first image information and the second image information collected by the camera device are mismatched.

[0031] When the first image information and the second image information match, the entry and exit passage of the confined space is opened to allow the operator to exit the confined space. When the first image information and the second image information do not match, the excavation passage of the confined space is closed to prevent the operator from exiting the confined space.

[0032] In order to remind the operator and the management personnel, an alarm message is sent through the alarm device to prompt the operator to find the first tool, or to prompt the management personnel to supervise the operator. The alarm device can be a buzzer and a red and blue light.

[0033] The confined space control method provided by an embodiment of the present invention can choose to open or close the entry and exit channels of the confined space based on whether the first image information of the first tool carried by the operator before entering the confined space and the second image information of the second tool carried by the operator before exiting the confined space match, thereby saving a lot of manpower and material resources and improving the management efficiency of tools.

[0034] In one possible implementation, after obtaining first image information of a first tool carried by a worker before entering the confined space through an access passage and opening the access passage to the confined space, at least one of the following is further included:

[0035] Acquire third image information of the operator, the third image information indicating the operator's behavior in the confined space, analyze the third image information, and issue an alarm signal if the operator's behavior in the confined space violates regulations.

[0036] Specifically, the workers entering the confined space are monitored by the camera equipment installed inside the confined space, that is, the workers' behaviors, such as the workers' operating behaviors using tools and other behaviors performed by the workers are collected by the camera equipment installed in the confined space. The operating behaviors of using tools include but are not limited to removing protective gear, putting on protective gear, using oxygen respirators, and using fire-fighting equipment, etc. Other behaviors include but are not limited to smoking and destroying confined spaces. After collecting the third image information, the third image information is analyzed. If the behavior contained in the third image information is illegal, an alarm signal is issued to prompt the workers to regulate their behavior and to prompt the management personnel to supervise the workers entering the confined space to ensure the safety of the workers working in the confined space.

[0037] Acquire monitoring values ​​of air indicators in the confined space, where the air indicators include at least one of oxygen content and toxic gas. If the monitoring values ​​exceed the safety limit, an alarm signal is issued.

[0038] Specifically, the oxygen content and toxic gases in the confined space can be detected by an oxygen measuring device and a toxic gas detection device. The oxygen content and toxic gases can respectively correspond to safety limit values. When the oxygen content and toxic gases exceed the corresponding safety limit values, an alarm signal is issued. The workers in the confined space are reminded to stop working immediately and exit the confined space or take protective measures to ensure the safety of the workers. In addition, a temperature measuring device and a humidity measuring device can be set in the confined space and corresponding safety limit values ​​can be set. After the temperature and humidity exceed the corresponding safety limit values, an alarm signal is issued. Among them, the safety limit value can be determined according to the actual situation, and the embodiments of the present application are not limited here.

[0039] In one possible implementation, before obtaining first image information of a first tool carried by a worker before entering the confined space through an access passage and opening the access passage to the confined space, the method further includes at least one of the following:

[0040] In response to a first input from a manager, a first location name of a first target confined space is obtained, a management process sheet corresponding to the first location name is obtained, and the management process sheet is displayed on a display device. Identity verification of the operator is performed using facial recognition technology, and upon successful authentication, access to the confined space is opened. In response to a second input from the operator, a second location name of a second target confined space is obtained, an operation item corresponding to the second location name is obtained, and the operation item is displayed on a display device.

[0041] Specifically, each confined space corresponds to a management process sheet. After the manager enters the location name of a confined space, the management process sheet of the confined space corresponding to the location name is retrieved and displayed on a display device to present it to the manager, so that the manager can manage the confined space.

[0042] In addition, before entering a confined space, the identity of the operator can be verified using methods including but not limited to facial recognition, voice recognition, and fingerprint recognition. It is worth noting that any person entering a confined space can be authenticated, prohibiting unauthorized personnel from entering the confined space.

[0043] Furthermore, after the operator inputs the location name of the confined space where he needs to work, the work items corresponding to the location name are retrieved and displayed on the display device, which is convenient for the operator to understand and improve the operator's work efficiency and standardization.

[0044] In one possible implementation, workers can have their temperatures taken with an infrared thermometer before entering a confined space. If the temperature is abnormal, the worker is warned not to enter the confined space, thus preventing accidents. Before entering a confined space, workers' safety briefings can also be recorded. Through random quizzes, workers with incorrect answers can be warned to suspend work.

[0045] In one possible implementation, permissions can be pre-configured for different staff members. For example, a chief engineer or technical director can be granted unrestricted access to any confined space within the factory. A specialized engineer can be granted access to confined spaces within their specific area of ​​expertise. Specific operators, on the other hand, must be granted access only to their specific confined space, and must be re-authorized each time they perform work.

[0046] The following describes a confined space control device provided in an embodiment of the present application. Figure 2 As shown, the confined space control device 200 includes a camera 201 , a memory 202 and a processor 203 .

[0047] The camera device 201 is connected to the memory 202 and the processor 203 respectively, and is used to respond to the first operation of the operator to open the entrance and exit channel of the confined space, shoot the first tool carried by the operator, output first image information, and respond to the second operation of the operator to open the entrance and exit channel of the confined space, shoot second image information of the second tool carried by the operator.

[0048] The memory 202 is used to store first image information, second image information and programs or instructions that can be run on the processor. When the program or instructions are executed by the processor, the following steps are performed: in response to a first operation by an operator to open the entrance and exit channel of the confined space, first image information of a first tool carried by the operator is obtained, and the entrance and exit channel of the confined space is opened to allow the operator to enter the confined space; in response to a second operation by the operator to open the entrance and exit channel of the confined space, second image information of a second tool carried by the operator is obtained, and the first image information is matched with the second image information; if the first image information and the second image information match, the entrance and exit channel of the confined space is opened to allow the operator to exit the confined space; if the first image information and the second image information do not match, the entrance and exit channel of the confined space is closed and an alarm signal is issued.

[0049] In one possible implementation, the camera device is further configured to capture third image information of the operator, and the memory is further configured to store the third image information. The apparatus further includes: a gas detection device configured to monitor the monitored values ​​of air indicators within the confined space. The processor is connected to the gas detection device, and when the program or instructions are executed by the processor, the following steps are implemented: obtaining third image information of the operator, the third image information indicating the operator's behavior within the confined space; analyzing the third image information; and issuing an alarm signal if the operator's behavior within the confined space violates regulations. Furthermore, the monitored values ​​of air indicators within the confined space are obtained, the air indicators including at least one of an oxygen content indicator and toxic gases, and issuing an alarm signal if the monitored values ​​exceed safety limits.

[0050] In one possible implementation, the apparatus further includes a display device, which is used to display a management process sheet and / or work items. When the program or instructions in the memory are executed by the processor, the following steps are implemented: in response to a first input from the management personnel, the first location name of the first target confined space is obtained, the management process sheet corresponding to the first location name is obtained, and the management process sheet is displayed through the display device; the identity of the operator is authenticated through face recognition technology, and if the identity authentication is passed, the entry and exit channels of the confined space are opened; in response to a second input from the operator, the second location name of the second target confined space is obtained, the work items corresponding to the second location name are obtained, and the work items are displayed through the display device.

[0051] It should be noted that the confined space control method provided in the embodiments of the present application can be executed by a confined space control device, or a control module in the confined space control device that is used to execute the confined space control method. In the embodiments of the present application, the confined space control method executed by a confined space control device is used as an example to illustrate the confined space control device provided in the embodiments of the present application.
