[0002] Oil resources are unevenly distributed around the world, which necessitates the construction of transit depots to transport oil from production sites to demand locations, thereby optimizing resource allocation.

[0003] When loading and unloading oil at a transit depot, the railway trestle unloading equipment (crane pipes, oil pumps, oil collecting pipes, etc.) is required. During the loading and unloading process, the trestle's pedestrian ladder, unloading crane pipes, and trough cleaning hoses must be in contact with the tank truck. After the unloading operation is completed, these equipment must be recovered. If the equipment is not effectively reset and remains in contact with the tank truck, the tank truck's movement could damage the equipment and even the trestle, resulting in risks such as personal injury or oil leaks.

Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments of this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this invention.

[0033] The present invention will be described in detail below with reference to specific implementation methods and the accompanying drawings.

[0034] Method Example

[0035] According to an embodiment of the present invention, a method for interlocking control of oil depot loading and unloading equipment is provided, such as Figure 1 FIG. 1 is a flow chart of the interlocking control of the oil depot loading and unloading equipment provided in this embodiment. The interlocking control method of the oil depot loading and unloading equipment according to the embodiment of the present invention includes the following steps:

[0036] S110, receiving a status change signal sent by a position detection switch of the loading and unloading equipment, wherein position detection switches are provided at key positions of the loading and unloading equipment, such as the pedestrian steps on the trestle and the oil unloading crane pipe, for detecting the reset status of the equipment.

[0037] S120. Based on the received signal, the operating state of the loading and unloading device is determined according to the preset interlocking logic. When the operating state of the loading and unloading device meets the interlocking control condition, an interlocking action signal is sent to the execution device.

[0038] S130: Receive a signal fed back by the execution device after executing the interlocking action according to the interlocking action signal.

[0039] The method provided in this embodiment receives a state change signal sent by a position detection switch of the loading and unloading equipment, obtains the state of the position detection switch as a standard for judging the operating state of the loading and unloading equipment, and can obtain an accurate basis for judgment; based on the received signal, the operating state of the loading and unloading equipment is judged according to the preset interlocking logic; when the operating state of the loading and unloading equipment meets the interlocking control condition, an interlocking action signal is sent to the execution device, and the operating state of the loading and unloading equipment is obtained by performing an interlocking logic judgment on the signal, and then it is judged whether the operating state of the loading and unloading equipment meets the interlocking control condition, and the interlocking action is executed, which can ensure the effective reset of the loading and unloading equipment to avoid dangerous events through interlocking control; the signal fed back after the execution device performs the interlocking action according to the interlocking action signal is received, and the action of the execution device is reconfirmed to ensure the working environment and the personal safety of the operators.

[0040] In one embodiment, a position detection switch is used to monitor key parameters, device status, or operating conditions in a system, and includes a contact position detection switch and a non-contact position detection switch.

[0041] A contact position detection switch is installed at a critical interlock control point. When the loading and unloading equipment reaches this critical interlock control point, the contact position detection switch changes state and sends a confirmation signal. Specifically, the contact position detection switch can be an explosion-proof travel switch. The mechanical moving part strikes the operating head of the travel switch, actuating the internal contacts and thus achieving circuit on / off control. When the moving part reaches a specific position, the travel switch is triggered, sending a signal to the control system to achieve position detection and control of the equipment.

[0042] A non-contact position detection switch is installed at the moving component. When the moving component moves into the preset range of the loading and unloading equipment, the non-contact position detection switch changes state and sends a ready signal. Specifically, it can be a magnetic proximity switch, mainly composed of a sensor and a trigger. The sensor is usually a magnetic sensitive element, such as a Hall effect element or a magnetoresistive element, which can detect changes in the magnetic field. The trigger controls the on and off of the switch based on the sensor signal. When a magnetic object approaches the switch, the magnetic field generated by it is detected by the sensor, triggering the switch to switch on and off.

[0043] The method provided in this embodiment detects the status of the equipment at the point by means of contact position detection switches set at the key control points of the interlocking and non-contact position detection switches at the moving component points, and can obtain the status information of the loading and unloading equipment in a timely manner, thereby providing effective data support for the interlocking control and ensuring the safety of the oil loading and unloading process of the transfer oil depot.

[0044] In one embodiment, the execution device performs an interlocking action, specifically including changing the status of the interlocking indicator light, the status of the release indicator light and the status of the road blocking facility. For example, when one or more point devices are not effectively reset, the interlocking indicator light (red) of the point in the central control display screen lights up, and at the same time the release signal light (red) located next to the railway dedicated line lights up, and the railway gate barrier cannot be lifted by pressing the switch; only after all interlocking points are normally reset, all point interlocking indicator lights (green lights) in the central control display light up, the release signal light (green) next to the railway dedicated line lights up, and the railway gate barrier can be lifted normally by pressing the switch.

[0045] The method provided in this embodiment can issue work instructions to the staff of the transfer oil depot through interlocking actions, ensuring that the vehicle release signal is displayed only after the oil depot loading and unloading equipment is completely reset, thereby improving management and control efficiency.

[0046] In one embodiment, the preset interlocking logic includes an OR gate between multiple position detection switches, an AND gate between multiple mid-end relays and indicator lights, an OR gate between multiple mid-end relays, an AND gate between multiple position detection switches, an AND gate between multiple mid-end relays and indicator lights, and an OR gate between multiple mid-end relays, such as Figure 2 As shown, it is a schematic diagram of the preset interlocking logic provided in this embodiment, in which a parallel circuit composed of multiple position detection switches is connected in parallel with a series circuit composed of multiple mid-end relays and indicator lights, and then connected to the negative pole of the power supply through a parallel circuit composed of multiple mid-end relays and an external distribution cabinet.

[0047] The method provided in this embodiment can ensure the safe and stable operation of the system and improve the safety of the transfer oil depot by constructing interlocking logic to uniformly manage and control the operating status of the docking and unloading equipment.
