Description

Technical Field

[0001] The present invention relates to the technical field of chemical environmental protection, and in particular to a method and system for collecting, storing and managing hazardous solid waste. Background Art

[0002] With the rapid development of the domestic chemical industry, chemical safety and environmental protection have also become important issues in the industry. The treatment of hazardous solid wastes in various chemical companies is not only an important link in chemical safety and environmental protection, but also the weakest link in chemical safety and environmental protection. The pain point is that due to environmental protection requirements, hazardous solid wastes cannot be discarded and discharged at will; and due to the requirements of safe production, hazardous solid wastes need to be properly handled. Under these two restrictions, the result is usually that chemical companies first accumulate and store hazardous solid wastes, and then look for treatment channels. However, this treatment method has huge safety hazards. The Xiangshui accident that shocked the world on March 21, 2019 is a typical case.

[0003] At present, the accident investigation team has found that the direct cause of the accident was that the nitration waste illegally stored in the old solid waste warehouse for a long time continued to accumulate heat and heat up, causing spontaneous combustion, and the combustion caused the explosion. The accident party deliberately concealed the information, illegally stored and illegally disposed of the nitration waste, and the safety and environmental protection management was chaotic, and routine inspections were fraudulent. In addition, relevant environmental assessment, safety assessment and other intermediary service agencies issued false and inaccurate evaluation reports. Emergency management departments at all levels also have problems in fulfilling their comprehensive supervision responsibilities for production safety.

[0004] As one of the consultants involved in the accident site disposal, we also found that most chemical companies currently store hazardous solid waste in concentrated piles. For cost-saving reasons, they usually store hazardous solid waste in disposable containers (such as woven bags, plastic barrels, etc.). Since these containers are not airtight, there are problems of leakage and environmental pollution. Therefore, chemical production companies will store these containers full of hazardous solid waste in closed rooms to meet the environmental protection requirements of the industrial park. This further leads to the self-generation of heat after the hazardous solid waste is concentrated and piled up.

[0005] And because disposable containers are poorly sealed, it is difficult to meet environmental protection and safety requirements during transportation. Currently, few hazardous waste disposal units are willing to transport and treat this type of waste salt over long distances. This has led to the fact that although there are some industrial waste salt treatment processes, except for the construction of industrial parks with supporting hazardous waste disposal units, it is difficult to centrally transport and treat hazardous solid wastes generated by other waste-producing units. In addition, companies often smuggle and discharge hazardous solid wastes for the purpose of cost saving. Regulatory departments at all levels also suffer from the difficulty of monitoring the transportation and storage of hazardous solid wastes and the inability to accurately control their whereabouts. Every year, a large amount of hazardous solid wastes are missing.

[0006] To solve the above urgent problems, it is necessary not only to strengthen human supervision, but also to design corresponding solutions through technological innovation, and at least to take into account the three needs of environmental protection, supervision, and processing costs at the same time, so that the solutions can be truly implemented and effectively applied. Summary of the invention

[0007] The embodiments of the present invention provide a method and system for the collection, storage and management of hazardous solid waste, which realizes the monitoring of the transportation and storage process of hazardous solid waste, can accurately grasp the position of each storage container and the state of the material in the container, solves the blind spot of the monitoring link, and solves the leakage problem of hazardous solid waste. It not only solves the problem of the difficulty of hazardous solid waste supervision, but also takes into account the anti-leakage requirements in national standards.

It should also be understood that terms, such as those defined in commonly used dictionaries, should be understood to have a meaning consistent with that in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless as defined herein.

[0027] The method flow presented in this embodiment can be implemented in a Figure 1 In the system shown, the system includes: a cloud data center, a storage container, a monitoring platform, a waste generation side terminal, and a disposal side terminal.

[0028] The cloud data center disclosed in this embodiment can be deployed on workstations, supercomputers and other devices, servers and other devices, or a server cluster composed of multiple servers for cloud data center operation at the hardware level. The cloud data center can exchange information and data with the monitoring platform, waste production side terminal, and disposal side terminal through the Internet or mobile wireless network. Generally speaking, since the storage container needs to be moved and transported at any time, the cloud data center mainly exchanges information and data with the communication module in the lock box of the storage container through the mobile wireless network.

[0029] Furthermore, the system described in this embodiment may also include a transport side terminal for scanning the QR code on the surface of the storage container and uploading vehicle information and the container identification. The transport side terminal is generally operated by the escort of the hazardous waste transport unit.

[0030] In practical applications, the monitoring platform can be understood as an information system that is connected to the communication interface of the cloud data center and is used by police departments, government departments, third-party regulatory agencies and other units that have monitoring and regulatory responsibilities, so that the cloud data center can promptly issue alarms to the units that have monitoring and regulatory responsibilities and promptly report the location and status of storage containers.

[0031] In actual applications, different functional departments can be divided into waste-generating units, hazardous waste transportation units and hazardous waste disposal units according to the generation, circulation and treatment process of hazardous solid waste. The terminal devices used by employees in these units (such as smartphones with cameras, employee computers with code scanning devices, etc.) can be understood as: waste-generating side terminals, disposal side terminals and transportation side terminals.

[0032] Terminal devices such as waste generation side terminals, disposal side terminals and transportation side terminals can be wireless terminals or wired terminals. Wireless terminals can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connection functions, or other processing devices connected to wireless modems. Wireless terminals can communicate with one or more core networks via a wireless access network (e.g., RAN, Radio Access Network). Wireless terminals can be mobile terminals, such as mobile phones (or "cellular" phones) and computers with mobile terminals. For example, they can be portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile devices that exchange language and / or data with wireless access networks. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. A wireless terminal may also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a terminal device, or a user equipment.

[0033] Optionally, the waste-generating side terminal, the disposal side terminal and the transportation side terminal may not use terminal equipment operated by personnel, but may use automated equipment. For example, the waste-generating side terminal may be a code scanning device installed at the discharge port of hazardous solid waste, which is used to scan the QR code on the surface of the storage container filled with hazardous solid waste at the discharge port. The code scanning device at the discharge port is connected to the background server, administrator computer or workstation of the waste-generating unit. These devices are used to upload the data scanned by the code scanning device at the discharge port to the cloud data center, and also upload the status information of the storage container, etc. Both the disposal side terminal and the transportation side terminal can use similar automated equipment, which can be purchased from existing equipment on the market and installed and networked through existing technical means.

[0034] The various information and data transmissions described herein can be used in various wireless communication systems, such as current 2G, 3G communication systems and next generation communication systems, such as Global System for Mobile communications (GSM), Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Wideband Code Division Multiple Access (WCDMA), Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency-Division Multiple Access (OFDMA) systems, Single Carrier FDMA (SC-FDMA) systems, General Packet Radio Service (GPRS) systems, Long Term Evolution (LTE) systems, and other such communication systems. A base station (e.g., access point) can be a device in an access network that communicates with wireless terminals over an air interface through one or more sectors. The base station can be used to convert received air frames to and from IP packets, and act as a router between the wireless terminal and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) network. The base station can also coordinate the attribute management of the air interface. For example, the base station can be a base station (BTS, Base TransceiverStation) in GSM or CDMA, a base station (NodeB) in WCDMA, or an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in LTE, and the present invention is not limited thereto.

[0035] In addition, the term "and / or" in this article is only a description of the association relationship between the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0036] The embodiment of the present invention provides a method for collecting, storing and managing hazardous solid waste, including:

[0037] S1. Receive a closing signal uploaded by a storage container, and obtain the location information and status information of the storage container.

[0038] S2. After the storage container arrives at the preset area, verification information is received. When the verification information passes the verification, an unlocking key is sent. The verification information includes the identification information of the hazardous waste disposal unit and the current status information of the storage container.

[0039] This embodiment provides a method for collecting, storing and managing hazardous solid waste, which is convenient for regulatory authorities at all levels to monitor the transportation and storage process of hazardous solid waste, and can accurately grasp the position of each storage container and the state of the material in the container. In addition, the storage container adopts a metal container such as a steel plate (the inner wall is painted with an anti-corrosion paint), and adopts a sealed container cover, which solves the leakage problem of hazardous solid waste and prevents the volatilization of hazardous gases therein, thereby not only solving the problem of difficult supervision, but also taking into account the anti-leakage requirements in national standards.

[0040] In this embodiment, the receiving of the closing signal uploaded by the storage container includes:

[0041] When the magnetic induction module senses that the container cover is closed, it sends a closing signal, and sends the closing signal to the cloud data center via the mobile wireless network through the communication module;

[0042] After receiving the closing signal, the cloud data center detects whether the location information and status information of the storage container are obtained. If not, a prompt message is sent to the waste-producing terminal.

[0043] Specifically, the obtaining of the location information, state information and container identification of the storage container includes:

[0044] After receiving the closing signal of the storage container, the current position information of the storage container is recorded; the status information uploaded by the waste-producing side terminal is received, and a mapping relationship between the status information and the container identifier is established, wherein the status information at least includes the weight information and sample information of the storage container.

[0045] Among them, a QR code is printed on the surface of the storage container, and the information recorded in the QR code includes the container identification; after the waste-producing side terminal scans the QR code printed on the surface of the storage container, the container identification and status filling interface are displayed on the waste-producing side terminal; the information input into the status filling interface is read, and the status information is obtained, that is, the code is scanned out of the barrel from the waste-producing unit.

[0046] The prompt information is used to prompt the operator of the waste-generating terminal to upload information in a timely manner, and prompt what information to upload. Generally speaking, it is necessary to upload status information, time and date, etc., where the status information at least includes the weight information and sample information of the storage container. This allows the cloud data center to know the amount and component category of the hazardous solid waste in the storage container.

[0047] Sample information is used to indicate the approximate composition and main compounds of hazardous solid waste in storage containers. Usually, a very small amount of sample (a few grams) can be taken from the storage container through the sampling port on the container cover and stored in a sample container such as a test tube. The sample is then transported together with the storage container to facilitate hazardous waste disposal units and supervision platforms to know the composition of the materials in the storage container, alleviating the problem of difficulty in confirming the composition of hazardous solid waste when it is currently placed and stacked in disposable containers such as woven bags.

[0048] If the storage container receives an unlocking signal before reaching the preset area, the container identification, status information and latest uploaded location information of the storage container are obtained; the container identification, status information and latest uploaded location information of the storage container are sent to the monitoring platform, so that the cloud data center and the supervision platform can track the location of the storage container and the opening and closing of the cover in real time.

[0049] In order to further improve the monitoring capability, this embodiment also includes: obtaining corresponding vehicle information according to the container identification of the storage container, and sending the corresponding vehicle information to the monitoring platform, so that the cloud data center and the supervision platform can obtain vehicle information in a timely manner, and the monitoring granularity is accurate to the location of the vehicle and the location of the storage container.

[0050] In this embodiment, the legality of the hazardous waste disposal unit can be understood as being able to find the registration information of the hazardous waste disposal unit by searching the database in the cloud data center, and the business license and related certificates of the hazardous waste disposal unit are legal and valid. The cloud data center can also send a query request to the supervision platform. If the supervision platform is connected to the information system of the relevant competent department (such as the emergency management department), it can directly query the validity of the certification information of the hazardous waste disposal unit from the information system of the relevant competent department. If it is valid, it means that the hazardous waste disposal unit complies with national laws and regulations, and is therefore determined to be "legal". This ensures the monitoring of hazardous waste disposal units and the monitoring of the hazardous waste disposal units' handling behavior of the currently delivered storage containers.

[0051] In this embodiment, by Figure 1The system of the structure shown and the above method flow realize the transfer of storage containers for storing hazardous solid waste, and ensure the safety and real-time monitoring of the storage containers during the opening / closing transportation process. The monitoring platform can obtain alarms in time, and at the same time directly determine the location of the problematic vehicle and storage container, thereby solving the blind spot of the monitoring link.

[0052] The container for storing and transporting industrial hazardous waste disclosed in this embodiment is composed of a container cover, a container shell and a container bottom; a locking rod is fixed to the bottom of the container cover, and a rack is processed on the locking rod; a lock box is fixed to the outer wall of the container shell, and a gear meshing with the rack on the inner side of the locking rod is installed in the lock box; the electronic components installed in the lock box include at least: a mainboard, a communication module, a magnetic induction module, a buzzer and a battery.

[0053] A positioning chip is installed on the main board, and positioning information is sent to the cloud data center through the communication module via the mobile wireless network. The magnetic induction module is used to sense the opening and closing of the container cover. The buzzer is used to alarm when the container cover is illegally opened. The battery is used to power the electronic components in the lock box.

[0054] Further, such as Figure 3 As shown, a pressure-proof depression is formed on the container cover by a stamping process, and a sampling port is provided on the pressure-proof depression. Optionally, an explosion-proof valve is also provided on the pressure-proof depression, and a pressure relief membrane is installed in the explosion-proof valve. When the pressure is greater than a designed threshold, the pressure relief membrane ruptures. In this embodiment, the sampling port cover can be designed as an explosion-proof valve, and the sampling port cover is a bolt cover with a through cavity, and a pressure relief membrane is installed in the cavity. It can also be understood as follows Figure 4 The sampling port cover with a pressure relief valve is shown. When the internal pressure increases rapidly, the pressure relief membrane ruptures, which plays an explosion-proof role.

[0055] The structure of the storage container can be Figure 2a-2dThe square barrel shown. The outer wall of the container shell 2 is formed by bending a metal plate, and a reinforcing rib 4 is provided on the outer wall of the container shell 2. The upper sealing gasket 1-1 is glued to the bottom of the container cover 1, and the lower sealing gasket 2-1 is built into the outer edge groove of the mouth of the container shell 2. When the container cover 1 is installed on the container shell 2, the upper sealing gasket 1-1 and the lower sealing gasket 2-1 are overlapped and sealed. The locking rod 5 is fixed to the bottom of the container cover 1, and a rack 5-1 is processed on the locking rod 5. The lock box 6 is fixed to the outer wall of the container shell 2, and a gear meshing with the rack 5-1 on the inner side of the locking rod 5 is installed in the lock box 6. It should be noted that the "container" described in this embodiment may also be referred to as a "barrel", "box", "box", etc., depending on the final shape formed by processing. Regardless of how it is called, it has the function of a closed container and has the structure of a container cover, a container shell and a container bottom, reinforcing ribs, a locking rod and a lock box. For example, if the "container" is processed into a barrel shape, the container cover, the container shell and the container bottom may be referred to as a barrel cover, a barrel body and a barrel bottom, respectively.

[0056] The container for storage and transportation of industrial hazardous waste provided by the embodiment of the present invention uses a metal material to make the container shell and adds reinforcing ribs, which ensures that the container can still maintain sufficient structural strength after containing a large amount of chemical hazardous waste, so that the container can be reused. Although the manufacturing cost of the metal container is higher than that of disposable containers such as plastic barrels and woven bags, after repeated use for many times, the average cost of each use can still be reduced; the use of a locking rod and a lock box ensures that the lid can be accurately positioned and closed, and at the same time, a double sealing gasket stacking design is adopted at the lid, so that the container lid can be sealed by its own gravity, thereby realizing the sealed storage of hazardous waste in the container. And because the container lid is sealed by its own gravity, when multiple containers are stacked, the stacked container can exert a greater weight on the container below, thereby further improving the airtightness of the lower container, and in an environment where multiple containers are concentrated and stacked in large quantities, it can further improve safety.

[0057] Among them, since metal materials such as steel plates are used to form the container shell by mechanical bending, the container shell can be formed with only one weld, which achieves the purpose of preventing the container from open flames and reduces the processing cost as much as possible. In the preferred embodiment, a steel plate with a thickness of greater than or equal to 2 mm can be used. For example, a thin steel strip with a width of 1000 mm and a thickness of 2 mm is bent by mechanical bending to obtain a container shell.

[0058] Specifically, the reinforcing ribs 4 are metal strips 4 - 2 welded to the outer wall of the container shell 2 , and the metal strips 4 - 2 welded to the outer wall of the container shell 2 are interwoven into a grid shape.

[0059] Preferably, the four outer walls surrounding the container shell 2 are formed by mechanically bending the metal plate. Figure 2b As shown, in each outer wall, a reinforcing vertical rib 4-1 is mechanically bent at a specified distance. It should be noted that transverse reinforcing ribs can also be provided according to specific production needs, which can be called reinforcing transverse ribs.

[0060] Taking the container as a barrel and the metal plate as a steel plate as an example, the container shell of this embodiment can be implemented in the following ways:

[0061] By mechanically bending the steel plate, three right-angled edges are folded to form the four outer walls of the container shell 2, and the fourth right-angled edge is connected by welding. By mechanically bending, a reinforcing vertical rib 4-1 with a width and height of 40mm*40mm is folded every 200mm in each outer wall. The barrel body is made of a whole steel plate, and the mechanical bending technology is adopted to fold three right-angled edges to form the four sides of the barrel body, and another right-angled edge is connected by welding to increase strength, compression resistance, and prevent deformation.

[0062] The reinforcing vertical ribs 4 - 1 are all formed by bending, without the need for additional welding processing, and can be directly formed in one step on a mechanical bending machine, thereby further reducing production costs.

[0063] Specifically, Figure 2c As shown, the edge of the container cover 1 is bent downward to form a container cover fold 1-2. The upper sealing gasket 1-1 has a width that is consistent with the width of the folded edge of the container shell 2, and the width of the upper sealing gasket 1-1 is greater than the width of the lower sealing gasket 2-1.

[0064] Since two layers of sealing gaskets are stacked up and down to seal, the upper sealing gasket 1-1 is glued to the bottom of the container cover, and the lower sealing gasket 2-1 is built into the outer edge groove of the upper opening of the container shell. The four sides of the container cover 1 are bent downward by a bending machine to form the container cover folding edge 1-2. The width of the upper sealing gasket 1-1 is consistent with the width of the protruding folding edge of the container shell, and the width of the upper sealing gasket 1-1 is greater than the width of the lower sealing gasket 2-1. The outer edge of the container shell 2 is folded by a folding machine and further welded into a trapezoidal groove, which is narrow at the top and wide at the bottom. The lower sealing gasket 2-1 is pressed into the groove by mechanical equipment, and the sealing gasket slightly protrudes from the upper opening of the container shell. The width of the upper sealing gasket 1-1 is greater than the width of the lower sealing gasket 2-1, which can effectively solve the problem of container cover damage caused by deviation caused by misalignment, and is convenient for unmanned AGV forklifts to pick up. The bottom of the container cover 1 is designed to bulge into the container, which can assist the AGV intelligent system to move the container cover to the container shell and play an auxiliary positioning role.

[0065] The container shell 2 adopts a trapezoidal groove design, which is narrow at the top and wide at the bottom. During the process of compacting and sealing the container cover, the force-bearing area of ​​the bottom of the sealing gasket in the groove is increased, and the force deformation of the sealing gasket is relatively uniform, ensuring its good sealing performance.

[0066] Furthermore, the maximum height of the container cover fold 1-2 formed by the edge of the container cover 1 being bent downward is greater than the length of the lock rod 5. When the container cover 1 is placed on the ground, the stability of the four lock rods 5 at the bottom of the cover is poor and the force is uneven, resulting in the lock rods 5 at the bottom of the cover being bent and broken. The four sides of the container cover are designed with the container cover fold 1-2, and the bending length is slightly greater than the length of the lock rod 5, which can protect the lock rod 5 and stack the containers. In addition, the sealing pad on the top of the container cover 1 can play a certain buffering role when the containers are stacked.

[0067] Further, such as Figure 2d As shown, a limiting device is installed in the lock box 6. The end 5-2 of the lock rod 5 extending downward is arrow-shaped, the inner side of the lock rod 5 is processed with a serrated rack 5-1, and the outer side of the lock rod 5 is polished into a smooth plane 5-3. When the lock rod 5 moves downward, it passes through the limiting device in the lock box 6. For example:

[0068] The locking rods 5 are fixedly installed at the middle positions of the four sides of the container cover 1 (i.e., one is installed on each side). The locking rods 5 are arrow-shaped, and the inner side of the locking rods 5 is a toothed rack 5-1, and the outer side is a smooth plane. The container cover 1 is accurately positioned by a locking rod 5 on each side and a lock box 6 matched with each locking rod 5.

[0069] The rack 5-1 inside the locking rod 5 passes through the limiting spur gear and the spur gear with the helical gear from top to bottom in sequence. The smooth plane outside passes through the limiting semi-guide rail and the limiting toothless roller in sequence from top to bottom.

[0070] The lock box 6 (the number and installation position match the lock rod 5 to ensure that the lock rod 5 can pass through the lock box 6) is fixed on the container shell. The lock box 6 is a wedge-shaped structure, which is connected to the limiting semi-guide rail. The left side of the limiting semi-guide rail is a limiting toothless roller, and the right side of the limiting semi-guide rail is a limiting spur gear and a spur gear with a helical gear. Among them, the helical gear is fixed on the spur gear and rotates synchronously. There is a braking check claw on the right side of the helical gear. The lower end of the braking check claw is connected to the leaf spring, and the upper end of the braking check claw is connected to the horizontal lock tongue. This prevents the container cover 1 from being opened at will after being pressed tightly closed.

[0071] The locking rod 5 is guided to move downward by a limiting device. By utilizing the gravity of the container cover itself, the inner rack 5-1 of the locking rod 5 meshes with the spur gear with the helical gear, driving the spur gear and the helical gear to rotate synchronously, and continuously tightening the seal. The leaf spring is used to press against the lower end of the brake check pawl, so that when the ratchet rotates, it can only rotate in one direction, so that the container cover 1 can be acted upon by its own gravity, the gravity of the containers stacked above the container, and the gravity of the detachable counterweight block and other external forces, thereby achieving a self-tightening seal. In the process of opening the cover, it is only necessary to connect the upper end of the brake check pawl with the lock tongue, and the lock tongue pushes the brake check pawl inward to disengage it from the helical gear, and the locking rod 5 can be lifted upward freely to achieve the purpose of opening the cover.

[0072] It should be noted that this embodiment only provides a possible implementation of the lock box in an exemplary form, but is not limited to this form.

[0073] Optionally, a detachable counterweight is installed on the container cover 1. In practical applications, the counterweight can be added when the containers are not stacked. If multiple containers are stacked, the counterweight can be added to the container cover 1 of the topmost container.

[0074] Optionally, the outer surface of the container bottom 3 is also provided with a fork groove to facilitate fork picking by an AGV forklift. For example, the four sides of the container bottom 3 are all the same fork grooves, the bottom beams are located on both sides and in the middle, and the four sides are arranged in the same way, forming a design that can be forked on all four sides, and the bottom fork groove iron is an integral plane, which also increases the force-bearing area.

[0075] At present, most chemical companies use the method of concentrated accumulation and storage of hazardous solid wastes. For cost-saving considerations, they usually use disposable containers (such as woven bags, plastic barrels, etc.) to hold hazardous solid wastes. Since these containers are not airtight, there are problems of leakage and environmental pollution. Therefore, chemical production companies will store these containers full of hazardous solid wastes in a closed room to meet the environmental protection requirements of the industrial park. This further leads to the self-generation of heat after the concentrated accumulation of hazardous solid wastes. And because the airtightness of disposable containers is very poor, it is difficult to meet environmental protection and safety requirements during transportation. The storage container for industrial hazardous waste storage and transportation provided in this embodiment adopts a metal container such as a steel plate (the inner wall is painted with an anti-corrosion coating) and a sealed container cover to solve the leakage problem of hazardous solid wastes and prevent the volatilization of hazardous gases therein. And because of the realization of anti-leakage, even if a large number of storage containers are concentrated and piled up, the hazardous solid wastes in the storage containers are isolated from each other, and it is difficult to accumulate energy, thereby fundamentally avoiding the possibility of concentrated accumulation of a large number of hazardous solid wastes and explosions. And because metal containers are used, although the unit cost is higher than disposable containers, since they can be reused, the average use cost is lower than that of disposable containers, which reduces the overall transportation cost of hazardous solid waste and facilitates large-scale application.

[0076] In this embodiment, a system for collecting, storing and managing hazardous solid waste is also provided. Figure 1 As shown, it includes: cloud data center, storage container, monitoring platform, waste generation side terminal, and disposal side terminal.

[0077] The cloud data center is used to receive the closing signal uploaded by the storage container and obtain the location information and status information of the storage container; if the storage container receives the unlocking signal of the storage container before reaching the preset area, an alarm is sent to the monitoring platform; after the storage container reaches the preset area, verification information is received, and when the verification information passes the verification, an unlocking key is sent, and the verification information includes the identification information of the hazardous waste disposal unit and the current status information of the storage container.

[0078] The storage container is composed of a container cover, a container shell and a container bottom. The lock rod is fixed to the bottom of the container cover. The lock rod is processed with a rack. The lock box is fixed to the outer wall of the container shell. The lock box is installed with a gear meshing with the rack inside the lock rod. The electronic components installed in the lock box include at least: a mainboard, a communication module, a magnetic induction module, a buzzer and a battery. The mainboard is installed with a positioning chip, and the positioning information is sent to the cloud data center via the mobile wireless network through the communication module. The magnetic induction module is used to sense the opening and closing of the container cover. The buzzer is used to alarm when the container cover is illegally opened. The battery is used to power the electronic components in the lock box.

[0079] The monitoring platform is used to receive the alarm information sent by the cloud data center, and the location information and status information of the storage container.

[0080] The waste generating side terminal is used to scan the QR code on the surface of the storage container and upload status information, and the information recorded in the QR code includes the container identification.

[0081] The transport-side terminal is used to scan the QR code on the surface of the storage container and upload the vehicle information and the container identification.

[0082] Furthermore, the system described in this embodiment may also include a transport side terminal for scanning the QR code on the surface of the storage container and uploading vehicle information and the container identification. The transport side terminal is generally operated by the escort of the hazardous waste transport unit.

[0083] In this embodiment, the cloud data center is also used to detect whether to obtain the location information and status information of the storage container after receiving the closing signal. If not, a prompt message is sent to the waste-producing side terminal, and the prompt message is used to prompt the user of the waste-producing side terminal to input the status information of the storage container.

[0084] In this embodiment, the cloud data center is further configured to record the current location information of the storage container after receiving the closing signal of the storage container, receive the status information uploaded by the waste generating terminal, and establish a mapping relationship between the status information and the container identifier, wherein the status information at least includes the weight information and sample information of the storage container.

[0085] Specifically, after the waste-producing terminal scans the QR code printed on the surface of the storage container, the container identification and status filling interface are displayed on the waste-producing terminal, and the information input into the status filling interface is read to obtain the status information.

[0086] In this embodiment, the cloud data center is further configured to obtain the container identification of the storage container, the state information of the storage container, and the latest uploaded location information if the storage container receives an unlocking signal of the storage container before the storage container reaches the preset area, and send the container identification of the storage container, the state information of the storage container, and the latest uploaded location information to the monitoring platform.

[0087] Specifically, the cloud data center is further used to obtain corresponding vehicle information according to the container identification of the storage container, and send the corresponding vehicle information to the monitoring platform.

[0088] This embodiment provides a system for the collection, storage, and management of hazardous solid waste, which is convenient for regulatory authorities at all levels to monitor the transportation and storage process of hazardous solid waste, and can accurately grasp the location of each storage container and the state of the material in the container. The monitoring platform can obtain alarms in a timely manner, and at the same time can directly determine the location of the problematic vehicle and storage container, thereby solving the blind spot of the monitoring link. In addition, the storage container adopts a metal container such as a steel plate (the inner wall is painted with anti-corrosion paint), and adopts a sealed container cover, which solves the leakage problem of hazardous solid waste and prevents the volatilization of hazardous gases therein, thereby not only solving the problem of difficult supervision, but also taking into account the anti-leakage requirements in national standards.
