Description

Technical Field

[0001] This application relates to the field of large container technology, and in particular to a vertical storage tank with a safety warning device. Background Technology

[0002] Storage tanks are containers used to store various chemical raw materials or finished products. They are generally installed within the plant area of ​​chemical production plants. Chemical raw materials or finished products transported by pipelines or transport vehicles will be temporarily stored in storage tanks so that they can be obtained at any time when needed.

[0003] As a type of production equipment, storage tanks also require regular inspection and maintenance. During maintenance, in addition to external operations, personnel often need to enter the tank for cleaning, repairs, and other tasks. However, storage tanks store various hazardous chemicals for extended periods. Even if the chemicals are purged before personnel enter, potential hazards such as oxygen deficiency and excessive chemical gas concentrations remain. Therefore, accurate environmental testing of the tank's interior is necessary before entry, and personnel should only be allowed entry if it is confirmed to pose no threat. For example, Chinese invention patent application CN114582107A discloses an intelligent early warning system for confined space operations, applicable to storage tank maintenance. This patent can accurately assess and warn of risks associated with various gases, ensuring the safety of personnel and equipment.

[0004] However, personnel safety requires continuous monitoring, not only before personnel enter the storage tank, but also after personnel enter the tank. However, existing technologies have not proposed safety early warning technologies for the entire process before and after personnel enter the storage tank. Summary of the Invention

[0005] This application provides a vertical storage tank with a safety warning device to solve the problem of insufficient safety warning work for personnel entering the storage tank in the prior art.

[0006] This application provides a vertical storage tank with a safety warning device, including a tank body and a top cover, and further comprising:

[0007] The detection sensors are installed at multiple locations inside the tank and are used to collect real-time environmental data of the tank.

[0008] The safety warning device is installed on the top of the tank. The safety warning device has a processing unit and a detection camera. After acquiring real-time environmental data, the processing unit determines the corresponding protection requirements. The detection camera is used to acquire the image of the first person. After the processing unit extracts the protective equipment information from the image of the first person, it compares the protective equipment information with the protection requirements. When the protective equipment information matches the protection requirements, the top cover is unlocked.

[0009] The wearable device is worn on the body of personnel. After personnel enter the tank through the top cover, the wearable device collects real-time data inside the tank and compares the real-time data with a data threshold. When the real-time data exceeds the data threshold, an early warning message is issued.

[0010] In one possible implementation, the safety warning device also has an operation unit for acquiring verification information input by personnel, a processing unit for verifying the verification information, and after the verification is passed, acquiring real-time environmental data and acquiring the first person image by the detection camera.

[0011] In one possible implementation, the safety warning device also has a prompting unit. After the verification is passed, the processing unit acquires real-time environmental data and determines the protection requirements, and broadcasts the protection requirements to the personnel through the prompting unit.

[0012] In one possible implementation, the top cover is located in front of the safety warning device. After the top cover is unlocked, the detection camera also acquires a second image of the personnel entering the tank through the top cover, determines whether the personnel in the second image meet the protection requirements, and broadcasts a warning message through the prompting unit when it is determined that any personnel do not meet the protection requirements.

[0013] In one possible implementation, the wearing device is placed on the safety warning device. After acquiring the second person image, the processing unit also determines the number of people in the second person image and compares the number of people with the number of wearing devices that have been used. When the number of people and the number of wearing devices that have been used do not match, a prompting message is broadcast to the people through the prompting unit.

[0014] In one possible implementation, the safety warning device is equipped with a charging dock for charging the wearable device placed on the safety warning device, and the processing unit determines the number of devices to be taken based on the number of wearable devices removed from the charging dock.

[0015] In one possible implementation, the wearable device also includes a monitoring camera, a communication unit, and an alarm unit. The communication unit is used for communication connection with the processing unit. The monitoring camera is used to acquire images of third personnel inside the tank. The images of the third personnel are sent to the processing unit through the communication unit. The processing unit determines whether the personnel in the images of the third personnel meet the protection requirements. If it is determined that a person does not meet the protection requirements, an alarm message is broadcast through the alarm unit.

[0016] In one possible implementation, the wearable device also has a monitoring sensor for collecting real-time data inside the tank. After the real-time data inside the tank is sent to the processing unit via the communication unit, the processing unit updates the protection requirements based on the real-time data inside the tank. The monitoring camera acquires an image of a third person, and the processing unit determines whether the person in the third person's image meets the updated protection requirements. If it is determined that a person does not meet the updated protection requirements, an alarm message is broadcast through the alarm unit.

[0017] The vertical storage tank with a safety warning device described in this application has the following advantages:

[0018] Before personnel enter the storage tank, the internal environment of the storage tank is tested, and the protective equipment worn by personnel is checked according to the internal environment of the storage tank. After personnel enter the storage tank, the environmental data of the personnel's location is monitored in real time, and an early warning is issued in a timely manner when the environmental data exceeds the set threshold, so as to ensure that personnel have a high degree of safety before and after entering the storage tank.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] Figure 1-2This is a schematic diagram of the structure of a vertical storage tank with a safety warning device provided in an embodiment of this application. The embodiment of this application provides a vertical storage tank with a safety warning device, including a tank body 100 and a top cover 110, and further comprising:

[0025] The detection sensors are installed at multiple locations inside the tank 100 and are used to collect real-time environmental data of the tank 100.

[0026] A safety warning device 200 is installed on the top of the tank 100. The safety warning device 200 has a processing unit and a detection camera 240. After acquiring real-time environmental data, the processing unit determines the corresponding protection requirements. The detection camera 240 is used to acquire the image of the first person. After the processing unit extracts the protective equipment information from the image of the first person, it compares the protective equipment information with the protection requirements. When the protective equipment information matches the protection requirements, the top cover 110 is unlocked.

[0027] Wearing device 250 is used to wear on the body of personnel. When personnel enter the tank 100 through the top cover 110, wearing device 250 collects real-time tank data inside the tank 100 and compares the real-time tank data with a data threshold. When the real-time tank data exceeds the data threshold, an early warning message is issued.

[0028] For example, the top cover 110 is located on the outer top of the tank 100. After the top cover 110 is opened, personnel can enter the tank 100 to perform cleaning, maintenance and other operations. In the embodiments of this application, an electromagnetic lock is installed on the top cover 110. The electromagnetic lock is controlled by a processing unit. After determining that the protective equipment worn by the personnel meets the protection requirements, the processing unit will control the electromagnetic lock to open, thereby unlocking the top cover 110.

[0029] Detection sensors are installed at multiple key locations inside the tank 100, covering areas that personnel would need to pass through during movement inside the tank 100, such as near the top cover 110 and the bottom of the tank. Depending on the chemicals stored inside the tank 100, the detection sensors need to detect the concentration of the corresponding gases. For example, if the tank 100 is used to store ammonia, the detection sensor will be an ammonia concentration sensor. Since multiple detection sensors are used in this application, the processing unit needs to determine the corresponding protection requirements based on the highest real-time environmental data collected by all the detection sensors, i.e., the gas concentration data.

[0030] In the embodiments of this application, the real-time environmental data is a precise numerical value. This application employs a fuzzy control method to divide multiple environmental data intervals, each corresponding to a protection requirement. When the real-time environmental data falls within one of these intervals, the protection requirement corresponding to that interval will be used as the protection requirement for that real-time environmental data. The protection requirement needs to be determined in advance based on the possible gas concentration inside the tank 100. The protective equipment that ensures personnel safety corresponding to that gas concentration is the protection requirement. For example, the possible gas concentration inside the tank 100 can be divided into three environmental data intervals: mild, moderate, and severe. For mild cases, personnel are required to wear protective clothing; for moderate cases, in addition to protective clothing, personnel should also wear a gas mask; and for severe cases, personnel are required to wear both protective clothing and an oxygen tank.

[0031] In this application, a ladder 120 is provided on the outer side of the tank 100, and a guardrail 130 is provided on the top surface. After personnel reach the top of the tank 100 via the ladder 120, they will stand in front of the safety warning device 200. At this time, the detection camera 240 can acquire a first image of the personnel containing full-body information. After analyzing the first image of the personnel, feature information of key positions such as the torso, limbs, and head can be extracted. Then, it is determined whether these feature information contains specific protective equipment. If the information of the protective equipment of the entire body of the personnel matches the protection requirements, it can be considered that the personnel are wearing protective equipment that matches the current protection requirements, and the personnel can be allowed to enter the tank 100.

[0032] The wearable device 250 can be worn on the head, chest, or other locations of a person. Once a person enters the tank 100 through the top cover 110, the wearable device 250 will collect real-time data about the inside of the tank at the person's location. This real-time data is the same as the real-time environmental data, both representing the gas concentration data inside the tank 100. Since the detection sensor can only be installed in a fixed position, while the person's position inside the tank 100 can change at any time, and the gases produced by the chemical products are not completely uniformly distributed inside the tank 100, real-time monitoring of the actual location inside the tank after the person enters is crucial for accuracy.

[0033] Specifically, the data threshold for comparison with real-time tank data can be the upper limit of each environmental data range when determining protection requirements. If the current real-time tank data does not exceed the upper limit of the environmental data range corresponding to the determined protection requirements, the environment in which the personnel are located is considered safe. Once the real-time tank data exceeds the upper limit of the environmental data range, it indicates that the protective equipment currently worn by the personnel can no longer ensure safety, and a warning message needs to be issued through the wearing device 250 to remind the personnel to immediately move to the outside of the tank 100.

[0034] In one possible embodiment, the safety warning device 200 also includes an operation unit 230, which is used to acquire verification information input by personnel, and the processing unit verifies the verification information. After the verification is passed, real-time environmental data is acquired, and a first personnel image is acquired by the detection camera 240.

[0035] For example, the storage tank is a production equipment and requires maintenance by qualified or authorized personnel. Therefore, personnel need to be authenticated before entering the tank 100. After personnel input verification information by touching or pressing buttons on the operating unit 230, the processing unit will compare the verification information with pre-stored identity information. If the verification information exists in the identity information, it indicates that the personnel who input the verification information are allowed to enter, and subsequent processing can continue. If the personnel's identity verification fails, a corresponding prompt message will be issued to remind the personnel that their identity is invalid.

[0036] In one possible embodiment, the safety warning device 200 also has a prompting unit. After the verification is passed, the processing unit obtains real-time environmental data and determines the protection requirements, and broadcasts the protection requirements to the personnel through the prompting unit.

[0037] For example, personnel may not know the internal conditions of tank 100 before entering it, and therefore cannot wear protective equipment that meets the requirements. In this case, personnel usually carry their protective equipment to tank 100, and after determining the internal conditions of tank 100 through observation and measurement, they then put on the appropriate protective equipment. At this time, the processing unit can determine the protection requirements based on real-time environmental data, and then broadcast the protection requirements in the form of voice, text, or graphics, eliminating the trouble of manual judgment. After receiving the protection requirements broadcast by the prompting unit, personnel can put on the appropriate protective equipment according to the protection requirements, thereby meeting the protection requirements, and then allowing the processing unit to unlock the top cover 110 to enter tank 100.

[0038] In one possible embodiment, the top cover 110 is located in front of the safety warning device 200. After the top cover 110 is unlocked, the detection camera 240 also acquires a second personnel image when personnel enter the tank 100 through the top cover 110, determines whether the personnel in the second personnel image meet the protection requirements, and broadcasts a prompt message through the prompt unit when it is determined that any personnel do not meet the protection requirements.

[0039] For example, in actual operation, there may be a situation where a person wearing protective equipment that meets the protection requirements passes identity verification, while other personnel not wearing any protective equipment, or whose protective equipment does not meet the protection requirements, enter the tank 100 for maintenance. In this case, the processing unit will acquire a second personnel image in real time, identify and track each person in the second personnel image. When any personnel are found to have entered the top cover 110, the processing unit will analyze the image of the personnel before entering the top cover 110 to determine whether the protective equipment worn by the personnel meets the protection requirements. If not, the alerting unit will broadcast an alert message so that all personnel are promptly informed of the situation.

[0040] Meanwhile, if personnel entering tank 100 without wearing protective equipment or with inadequate protective equipment do so, a serious accident will occur. To facilitate liability determination after an accident, the processing unit will also save the information on personnel wearing protective equipment when entering tank 100 and simultaneously upload it to the factory's data center.

[0041] In one possible embodiment, the wearing device 250 is placed on the safety warning device 200. After acquiring the second person image, the processing unit also determines the number of people in the second person image and compares the number of people with the number taken by the wearing device 250. When the number of people and the number taken by the wearing device 250 do not match, a prompting message is broadcast to the people through the prompting unit.

[0042] For example, during the analysis of the second personnel image and tracking of each person, the processing unit has already determined the number of personnel. At this point, it only needs to compare this number with the number of times the wearing device 250 has been used to determine whether each person is wearing a wearing device 250. If the number of wearing devices 250 used is less than the number of personnel, it indicates that some personnel have not used their wearing devices 250. In this case, the prompting unit will broadcast a prompt message to encourage personnel to use their wearing devices 250 promptly.

[0043] In the embodiments of this application, a charging dock is provided on the safety warning device 200. The charging dock is used to charge the wearable device 250 placed on the safety warning device 200. The processing unit determines the number of wearable devices 250 to be taken based on the number of wearable devices 250 removed from the charging dock.

[0044] Specifically, the wearable device 250 may contain a battery and have charging contacts on its outer casing. These charging contacts are connected to the battery's charging circuit. When the wearable device 250 is placed on the safety warning device 200, the charging contacts will contact the charging socket on the safety warning device 200, thereby charging the battery. When the wearable device 250 is not used, the charging socket will connect to the charging contacts, thus sending a signal back to the processing unit. Therefore, the number of used wearable devices 250 can be determined based on the number of charging sockets that have sent signals and the total number of charging sockets.

[0045] Furthermore, the safety warning device 200 includes a base 210 and a baffle 220. The base 210 is installed on the tank 100, while the baffle 220 is located above the base 210 to shield the base 210. The operating unit 230 and the wearing device 250 are both located on the top of the base 210, while the detection camera 240 is set on the upright plate connecting the base 210 and the baffle 220.

[0046] In one possible embodiment, the wearable device 250 also includes a monitoring camera, a communication unit, and an alarm unit. The communication unit is used for communication connection with the processing unit. The monitoring camera is used to acquire images of a third person inside the tank 100 and send the images of the third person to the processing unit through the communication unit. The processing unit determines whether the person in the third person image meets the protection requirements. When it is determined that a person does not meet the protection requirements, an alarm message is broadcast through the alarm unit.

[0047] For example, although the detection camera 240 has collected information on all personnel wearing protective equipment before they enter the tank 100, this work cannot be completed accurately when the detection camera 240 is blocked. However, the monitoring of personnel wearing protective equipment still needs to be carried out. Therefore, this application continues to monitor the wearing of protective equipment after personnel enter the tank 100.

[0048] When personnel use the wearing device 250 and move inside the tank 100, the monitoring camera of the wearing device 250 can collect information on the protective equipment worn by other personnel besides the person currently using the wearing device 250. Once everyone has used the wearing device 250, the information on the protective equipment worn by all personnel entering the tank 100 will be collected. The third-person image captured by the monitoring camera of each wearing device 250 will be sent to the processing unit. After analysis and processing, the processing unit will determine whether there are any personnel who do not meet the protection requirements. If so, the alarm unit on the wearing device 250 other than the one that captured the third-person image containing the person who does not meet the protection requirements will broadcast an alarm message.

[0049] In one possible embodiment, the wearable device 250 also has a monitoring sensor for collecting real-time data inside the tank. After the real-time data inside the tank is sent to the processing unit through the communication unit, the processing unit updates the protection requirements based on the real-time data inside the tank. The monitoring camera acquires an image of a third person, and the processing unit determines whether the person in the third person image meets the updated protection requirements. If it is determined that a person does not meet the updated protection requirements, an alarm message is broadcast through the alarm unit.

[0050] For example, since the protection requirements are determined based on real-time environmental data collected by detection sensors located at fixed positions inside the tank 100, there is a certain difference between the gas concentration environment at the personnel's location and the actual environment. If, after updating the protection requirements, the level of protective equipment worn by any personnel is equal to or higher than the updated protection requirements, then the environment at the personnel's current location is considered not to pose a safety threat. Conversely, if the level of protective equipment worn by any personnel is lower than the updated protection requirements, then the environment at the personnel's current location is considered to pose a safety threat. In this case, the alarm units of all wearing devices 250 need to play alarm information to prompt personnel to check the wearing status of their protective equipment and to immediately transfer personnel whose protective equipment does not meet the protection requirements to the outside of the tank 100.

[0051] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0052] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
