Description

Technical Field

[0001] This invention relates to the field of hazardous materials safety management technology, and in particular to a hazardous materials management method with multi-level safety management measures. Background Technology

[0002] The research and development and use of hazardous materials are generally divided into three stages: commissioning, storage, and operation. Each stage has different requirements for functional safety and ease of use. To ensure the safety and reliability of hazardous materials at each stage, safety control measures must be implemented. During commissioning, the operational status and timing signals of the hazardous materials must be verified normally without activating them. When entering storage after commissioning, the safety of the storage state must be fully considered to prevent activation due to environmental issues such as static electricity or accidental operation. When hazardous materials are removed from storage and prepared for operation, both safety and ease of use must be considered.

[0003] Therefore, for the safety management of certain types of hazardous materials, there is an urgent need to develop a hazardous materials management method with multi-level safety control measures to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to design a dangerous goods management method with multi-level safety control measures to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A method for controlling hazardous materials with multi-level safety control measures is applied to a hazardous materials control line. The hazardous materials control line includes a hardware switch, an electrical control switch, a hardware plug, a hazardous materials triggering unit, and a storage box. The hardware switch, electrical control switch, hardware plug, and hazardous materials triggering unit are connected in series on a single line. The storage box is connected to the hardware plug, the hazardous materials triggering unit, and the line on the side of the hazardous materials triggering unit away from the hardware plug, respectively.

[0007] Hazardous materials control methods include the following steps:

[0008] S1, Level 1 control: The control loop is controlled by a hardware switch. The closed state of the hardware switch determines whether the first level of the loop is conducting.

[0009] S2, Second-level control; The control signal serves as the control command for this level of control. When the first condition is met, the control command is issued to control the electronic switch to change from the open state to the closed state, thereby determining whether the second level of the circuit is connected.

[0010] S3, Level 3 control; Hazardous materials are controlled through multi-directional hardware plugs. Different types of multi-directional hardware plugs are used during commissioning / storage / operation to ensure that the activation circuit is in a connected or short-circuit protected state.

[0011] S4, Level 4 Control: This level is in the conductive state when the dangerous goods are not packed. After the dangerous goods are packed, the storage box will short-circuit the dangerous goods triggering unit.

[0012] Specifically, during the debugging phase, the process is used to verify that the hazardous materials activation procedure and sequence are normal without activating the hazardous materials; this includes:

[0013] 1) When the hardware switch at the first-level control point is closed, this level is in a conductive state;

[0014] 2) When the first condition is met, a control command is issued, the second-level control is in the conducting state, and the correctness of this level of control is verified in the debugging state;

[0015] 3) The multi-directional hardware plug at the third-level control point is selected as the installation and debugging plug. This level is under control and the hazardous materials triggering unit is in a short-circuit state.

[0016] 4) The hazardous materials are disconnected from the storage container, and the Level 4 control is in the conductive state.

[0017] Specifically, when in a storage state, it includes:

[0018] 1) The hardware switch at the first-level control point is off, and this level is in control mode;

[0019] 2) The system loses power and no commands are issued; the second-level control is in a controlled state.

[0020] 3) The multi-directional hardware plug at the third-level control point is selected as a protective plug, and this level is under control.

[0021] 4) The storage box short-circuits the hazardous materials triggering unit, and the fourth level is under control.

[0022] Specifically, when in a working state, this includes:

[0023] 1) When the hardware switch at the first-level control point changes from the open state to the closed state, this level changes from the control state to the conduction state;

[0024] 2) When the system is powered on, a command is issued when the first condition is met, and the second stage is in the conducting state;

[0025] 3) The multi-directional hardware plug at the third-level control point is selected as the installation working plug, and this level is in the conductive state;

[0026] 4) The hazardous materials are disconnected from the storage container, and the Level 4 control is in the conductive state.

[0027] The beneficial effects of this invention are as follows:

[0028] This application employs multi-level hardware / software control measures to ensure the safety of hazardous materials triggering, providing strong support for the safety management of hazardous materials in different states. Attached Figure Description

[0041] Hazardous materials control methods include the following steps:

[0042] S1, Level 1 control: The control loop is controlled by a hardware switch. The closed state of the hardware switch determines whether the first level of the loop is conducting.

[0043] S2, Second-level control; The control signal serves as the control command for this level of control.

[0049] 3) The multi-directional hardware plug at the third-level control point is selected as the installation and debugging plug. This level is under control and the hazardous materials triggering unit is in a short-circuit state.

[0050] 4) The hazardous materials are disconnected from the storage container, and the Level 4 control is in the conductive state.

[0051] like Figure 3 As shown, when in storage, safety considerations must be fully taken into account to avoid the activation of hazardous materials due to environmental issues such as static electricity or misoperation; specifically including:

[0052] 1) The hardware switch at the first-level control point is off, and this level is in control mode;

[0053] 2) The system loses power and no commands are issued; the second-level control is in a controlled state.

[0054] 3) The multi-directional hardware plug at the third-level control point is selected as a protective plug, and this level is under control.

[0055] 4) The storage box short-circuits the hazardous materials triggering unit, and the fourth level is under control.

[0056] like Figure 4 As shown, when in working condition, both the safety of hazardous materials and ease of use are considered; specifically including:

[0057] 1) When the hardware switch at the first-level control point changes from the open state to the closed state, this level changes from the control state to the conduction state;

[0058] 2) When the system is powered on, a command is issued when the first condition is met, and the second stage is in the conducting state;

[0059] 3) The multi-directional hardware plug at the third-level control point is selected as the installation working plug, and this level is in the conductive state;

[0060] 4) The hazardous materials are disconnected from the storage container, and the Level 4 control is in the conductive state.
