[0024] As introduced in the background technology, the existing manual valve operation method has problems such as low efficiency, reliance on manual operation, and inability to quickly adapt to new process formulas, which may lead to production losses and reduced efficiency. In order to solve the above technical problems, this application proposes a crude oil supply device and a crude oil supply system.

[0025] Figure 1 A crude oil supply device is shown, such as Figure 1 As shown, it includes a first controller 101, a second controller 102, a valve controller 103 and a storage 104 which are communicatively connected in sequence, wherein the first controller 101 is used to send a control signal to the second controller 102 using a predetermined communication protocol, the second controller 102 is used to receive the control signal and forward the control signal to the valve controller 103, the valve controller 103 is used to control the opening or closing of a valve 105 of the storage 104 according to the control signal, and the storage 104 is used to store crude oil.

[0026] Specifically, crude oil supply equipment is used to transport, store and supply crude oil to refineries or other industrial facilities. Crude oil supply equipment is generally composed of crude oil pipelines, oil storage tanks, pumping stations, monitoring and safety equipment, etc. Its main function is to ensure the stable supply and quality of crude oil and promote the normal operation of industrial production.

[0027] The above embodiment provides a crude oil supply device, including a first controller, a second controller, a valve controller and a storage device which are sequentially connected in communication, wherein the first controller is used to send a control signal to the second controller using a predetermined communication protocol, the second controller is used to receive the control signal and forward the control signal to the valve controller, the valve controller is used to control the opening or closing of the valve of the storage device according to the control signal, and the storage device is used to store crude oil. Through the communication technology between the first controller and the second controller, automatic control of the crude oil supply device can be achieved to reduce dependence on operators and improve production efficiency and accuracy. This solves the problem that crude oil valve control in the prior art mainly relies on manual operation, which is inefficient and prone to errors.

[0028] In one embodiment, the storage device includes a valve for controlling the output of the crude oil, wherein the valve is at least one of an intelligent valve, an electric valve, and a wireless control valve. This structure can further reduce the dependence of the crude oil supply device on the operator and improve production efficiency and accuracy.

[0029] Specifically, smart valves refer to valves that integrate computer processors, sensors and actuators, which can make independent judgments and controls, and automatically control the medium within the target flow, pressure and temperature range. Smart valves can communicate with the host through serial ports or network interfaces, transmit and receive various parameters and states, and also have self-diagnosis and reminder functions. Electric valves refer to valves that control the position, opening and flow of valves through motors, transmission mechanisms and drivers. Electric valves can use redundant servo motors as actuators to accurately control the opening and further achieve control accuracy. Wireless control valves refer to valves that use wireless technology for control and monitoring. They communicate with the control system through smartphones or other wireless terminal devices to achieve remote control and monitoring.

[0030] In another embodiment, the valve controller includes: an actuator for executing the control signal and controlling the valve according to the control signal. This structure can improve the accuracy and efficiency of the system and further reduce the error and cost of human intervention.

[0031] Specifically, the actuator can control the opening of the valve through electrical signals, and can achieve precise flow control, thereby improving the flow efficiency and control accuracy of the medium in the pipeline. In addition, electrical control can also provide better adaptability and scalability, adapt to different ranges of flow and pressure requirements, and can cooperate with other control devices to form a more complete control system. In this way, the automated control can be faster, more convenient and more reliable, reducing operating costs and improving the safety and reliability of the system.

[0032] In actual applications, all valves are controlled and monitored using command output bytes or status input bytes. All interface signals are sent or received by the controller to the main controller for data mapping and data management to control the valve. Among them, the status input byte includes valve position status, set point, safety status signal and fault alarm status. The valve position status is used to indicate whether the valve is open, closed or in an intermediate position; the set point refers to the electric valve has reached the preset position or meets the target state required by the command issued by the PLC. The safety status signal is used to represent the current state of the emergency stop, remote device or system. Safety-related signals such as not ready will also be reflected in the status input byte. The fault alarm status indicates that if there is any valve mechanical failure, electrical failure or out of normal operating range, the byte will display the corresponding fault code. The command output byte includes valve switch command, fieldbus set point, reset command and stop command. The valve switch command uses one or more bits to indicate whether the valve should be opened or closed, or requires the valve to move to a specific position; the fieldbus set point refers to the specific value of the working position, temperature, pressure, flow and other parameters that the electric valve or other controlled equipment needs to reach. The reset command instructs the MOV valve to close and return to a known safe position, or to clear abnormal conditions, such as alarm signals and fault conditions. The stop command is used to instruct the electric valve or other related equipment to stop the current operation or process.

[0033] In order to further improve the stability and safety of the crude oil supply device, the crude oil supply device also includes: a redundancy device for replacing the first controller in case of failure of the first controller, or for replacing the valve controller in case of failure of the valve controller.

[0034] Specifically, Figure 2 A redundancy device is shown, including a transport pipeline 106 and a pump 107. By adding a transport pipeline 106 in the recycling line of the storage tank 104, the pump 107 is used as a backup redundancy process for all transport pumps, as the above-mentioned redundancy device 108, to eliminate crude oil exchange restrictions and improve the stability and safety of the system.

[0035] In one embodiment, the crude oil supply device further comprises: a DP / DP coupler, which is used as a gateway for the predetermined communication protocol. This structure can further avoid control conditions when the crude oil supply device network fails.

[0036] Specifically, the DP / DP coupler can connect field devices to the field bus and realize data conversion and transmission, thereby simplifying the system architecture. In addition, by using the DP / DP coupler as a Profibus gateway, the information of field devices can be integrated into the Profibus network, realizing information exchange between field devices and control systems, and facilitating monitoring and control.

[0037] In another embodiment, the predetermined communication protocol is one of EtherNet / IP, Modbus TCP / IP, Profinet and Profibus. The above structure can further enhance the stability and fault tolerance of the crude oil supply device.

[0038] Specifically, EtherNet / IP is an industrial communication protocol based on Ethernet and TCP / IP protocols. It supports real-time data transmission and control, and has high reliability and strong network scalability. EtherNet / IP adopts an object-oriented communication method, supports point-to-point communication and multicast communication between devices, and can realize functions such as real-time monitoring, remote control, fault diagnosis and data acquisition. Modbus TCP / IP is an industrial communication protocol based on TCP / IP protocol. It is simple, reliable and mature. Modbus TCP / IP supports point-to-point communication and multi-node communication, has high interaction efficiency, and is suitable for applications such as data acquisition, parameter adjustment, and remote monitoring and control. The Modbus TCP / IP communication protocol adopts a master-slave architecture, and the master station can read and write to the slave station by sending instructions. Profinet is an open industrial Ethernet protocol for real-time Ethernet communication. It is a high-performance and high-reliability communication protocol. Profinet supports real-time data transmission and control, and has the characteristics of high real-time performance, stable communication cycle and low latency. Profinet adopts a distributed control method, supports large-scale network topology, and can simultaneously support multiple transmission media and transmission rates. Profibus is an industrial fieldbus communication protocol that supports real-time data transmission and control. Profibus has the characteristics of high reliability, high performance and flexibility, and can achieve long-distance transmission through serial communication or optical fiber communication. Profibus supports data exchange between slave stations and master stations, and provides a variety of topological structures and transmission rate options, suitable for control systems of different scales and complexities.

[0039] The first controller is a distributed control system. This structure can further realize temporary control from the local controller even if the main controller has problems.

[0040] Specifically, a distributed control system is a control system used for industrial automation, which consists of multiple decentralized control units, each of which is responsible for controlling a specific part or process. A distributed control system consists of multiple distributed controllers, which are connected and communicate with each other through a network. Each distributed controller is responsible for the control of a specific process or equipment, can operate independently, and can communicate and interact with other controllers. Distributed control systems have good scalability, and controllers can be added or removed as needed to adapt to control systems of different sizes and complexities. New controllers can be easily integrated into the system and communicate and coordinate with existing systems. Distributed control systems use network communication to connect different controllers and share data and information. Common communication protocols include Ethernet, Profibus, Modbus, etc. Network communication allows real-time data transmission and command interaction between different controllers, thereby achieving collaborative control and data sharing. Distributed control systems usually have high reliability and redundancy to ensure the stability and reliability of the system. Common redundancy technologies include redundant controllers, redundant power supplies, redundant networks, etc. When a controller or component fails, the system can automatically switch to the backup device to ensure the continuity and availability of the system.

[0041] In a specific embodiment, the second controller is a programmable logic controller. This structure can further improve the integration and standardization of the crude oil supply device and reduce the cost and time of integration and deployment.

[0042] Specifically, a programmable logic controller (PLC) is an industrial control device used to control, automate and monitor various industrial processes and equipment. PLC consists of a set of digital and analog input / output interfaces, a processor, memory and programming software, which can receive input signals, perform logical processing and output control signals. PLC is mainly used to control, automate and monitor various industrial processes and equipment. It can receive input signals from different types of sensors and switches, perform logical processing according to preset programs, and send corresponding control signals to output devices. PLC programs are written in a specific programming language, and each program is compiled into binary code and stored in the memory of the PLC. PLC can receive digital and analog input signals and send relevant control signals to digital and analog output devices. Digital input can represent switch states and digital signals, and analog input can represent analog signals such as temperature, pressure and humidity. Digital output can drive digital devices such as motors, pneumatic valves and digital indicators, and analog output can adjust analog parameters such as voltage, current and frequency.

[0043] The programmable logic controller includes a POWERLINK interface for communicating with the valve controller. Through the POWERLINK interface, the structure can further achieve efficient, reliable and real-time communication and further improve the performance and flexibility of the crude oil supply device.

[0044] Specifically, the POWERLINK interface is a real-time Ethernet communication interface standard used in the field of industrial automation.
