[0021] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:
[0022] Example: Refer to Figure 1 - Figure 4As shown in the figure, an integrated machine for loading and unloading hazardous chemicals, which combines batch control and process control, includes a body 1. A batch controller 2 and a process control touch screen 3 are respectively provided on both sides of the upper end of the body 1. A vehicle electrostatic discharge component is provided on the right end of the body 1, including an oil overflow electrostatic plug 5 and an oil overflow electrostatic socket 13. The oil overflow electrostatic plug 5 is electrically connected to the connector 4 on the right end of the body 1 through a cable. The oil overflow electrostatic socket 13 is installed on the tanker truck.
[0023] The front of the main body 1 is also provided with a key storage compartment 9. The key storage compartment 9 has a key insertion hole 10 in the middle of its inner side. The inlet end of the key storage compartment 9 is provided with a sealing door 7. The outer surface of the sealing door 7 is equipped with a hemispherical electrostatic touch ball 8. The sealing door 7 is opened and closed by an electromagnetic lock.
[0024] The front of the main body 1 is also equipped with a human infrared sensor 11 and a voice speaker 12. The human infrared sensor 11 and the voice speaker 12 are located on the left side of the key storage compartment 9. The human infrared sensor 11 can detect the driver's position with infrared, and the voice speaker 12 can provide voice prompts for the driver's operation process.
[0025] In some examples, a storage socket 6 is provided on the upper right side of the body 1. When the oil overflow static electricity plug 5 is in an unused state, the oil overflow static electricity plug 5 is inserted into the storage socket 6 and left to stand.
[0026] In some examples, both the display screen 21 and the process control touch screen 3 in this invention use 8-inch LCD screens, which facilitates operation and playback of process images.
[0027] In some examples, the batch controller 2 includes a display screen 21, a button control panel 22, and a card reader 23. The batch controller 2 is mainly used by the driver to control the refueling and flow of the tanker truck.
[0028] The batch controller 2 of this utility model is a general-purpose product, especially suitable for the dispensing and management systems of various oil products. When used in conjunction with a primary instrument, the metering accuracy can reach 3‰, and it is easy to operate. The machine uses a dual-screen backlit LCD, providing intuitive and clear display. It can be used independently or networked.
[0029] The batch controller 2 used in this utility model complies with the national petroleum quality measurement standard GB / T1885—1998; the explosion-proof structure is rated as ExdbIIBT6Gb, and the operating temperature is -40~+60℃.
[0030] One batch controller 2 can control the delivery of multiple loading arms; it can control settlement by quality and volume; and it can handle both bulk and drum delivery. The system can support a maximum of 32 batch controllers 2, which can operate in parallel. It has both networked and stand-alone operating modes; it has an internal self-test function that displays errors when they occur; it has power-off protection and the ability to remember the working state before power failure, and it can resume the original operation after power is restored.
[0031] The on-site operation features a delivery start button and an emergency stop button; it offers temperature compensation for quality settlement through both manual and automatic temperature sampling; it supports both drum and bulk packaging control and display modes; the standalone LCD screen is unaffected by ambient light, and its backlight ensures clear visibility during nighttime operation.
[0032] The clock and calendar operation of the standalone unit is unaffected by power outages; the dual π filter module and structural design of the power input line give the standalone unit strong resistance to electromagnetic interference and low electromagnetic leakage; the internal electrostatic grounding and oil spill protection detection circuit solves the problem of safe delivery; the designed overflow alarm and delivery interlock make delivery safer and more reliable; the alarm device adopts a built-in design and installation method, which effectively improves the system's safety and integration.
[0033] To improve the accuracy of oil product settlement and control, the batch controller 2 performs temperature compensation twice per second. At the same time, to ensure the safety of the flow rate quantitative control accuracy, the overall design adopts a method of modifying key coefficients using soft passwords and hard lead seals, which is more adaptable to the needs of users at all levels of management.
[0034] Since the batch controller 2 is installed in a semi-open environment, for equipment safety reasons, the circuit design adopts three levels of lightning protection and anti-static measures. When encountering a sudden surge in strong current, the circuit's discharge, current blocking, voltage reduction, and transient suppression will provide maximum protection for the machine. Secondly, the power supply circuit inside the explosion-proof enclosure has added an anti-electromagnetic interference module, and the hardware and software design of the microcomputer simultaneously adopts watchdog timer (WDT) technology, which greatly improves the machine's operational stability.
[0035] In addition to its own protection, the batch controller 2 also takes into account the related equipment in use. The machine's powerful configuration software can regulate the first-stage, second-stage, and multi-stage valves and oil pumps on site, minimizing the water hammer and vibration experienced by the equipment. Its slow start-up, constant flow maintenance, full-speed opening, and slow closing during the control process avoid the static electricity hazards caused by oil injection, as well as the overshoot and water hammer caused by closing. It solves the control accuracy problem of small-volume oil replenishment, and the whole process is smooth and stable.
[0036] The batch controller 2 is also equipped with a smart IC card as a bill of lading carrier for convenient management. The IC card is read by the card reader 23. The IC card's oil delivery function (bill of lading card) involves the billing machine writing the bill of lading card while issuing the invoice to the downstream machine. The delivery personnel use this card to swipe at the corresponding oil storage location and press the delivery button to retrieve and confirm the delivery parameters. This improves the confidentiality of the oil delivery number, reduces the printing time and cost of invoicing, prevents errors in oil storage location numbers, and prevents incorrect bill of lading number input.
[0037] The working principle of this utility model is as follows:
[0038] When the tanker truck driver needs to fill the tanker truck, he first parks the tanker truck in the designated position and then operates the machine body 1.
[0039] When the human infrared sensor 11 detects someone approaching the machine 1, the voice speaker 12 will provide a voice prompt to the driver to operate according to the procedure. At this time, the driver can operate the process control touch screen 3 to perform the process operation. At the same time, the voice speaker 12 will provide synchronous voice prompts to assist. Under the control of the process, the electromagnetic lock of the sealed door 7 is in the open state, so that the driver can push the electrostatic touch ball 8 to open the sealed door 7. While pushing the electrostatic touch ball 8, the static electricity on the driver's body can also be released. After opening the sealed door 7, the driver needs to insert the tanker truck key into the keyhole 10 for storage, and then close the sealed door 7 and lock it through the electromagnetic lock, thus forming a smart key management system.
[0040] The next step is to remind the driver to take the overflow static electricity plug 5 and connect it to the overflow static electricity socket 13 installed on the tanker truck to ground the tanker truck, thereby releasing the static electricity on the tanker truck and completing the entire operation process.
[0041] Only then can the driver load the vehicle through the batch controller 2. During the loading process, in conjunction with existing technologies (metering module and control module), the display screen 21 can display the type and quantity of oil injected and the entire loading process in real time, and promptly stop, warn and alarm the vehicle.
[0042] The core technology of this utility model is:
[0043] 1. This utility model of an integrated machine integrates batch control and process control into one device. During use, the driver only needs to operate one device to complete process control and batch filling control, which simplifies the driver's work process and improves filling efficiency.
[0044] 2. This utility model all-in-one machine has functions such as visitor reminder, human body static electricity release, intelligent key management, vehicle anti-static and anti-overflow functions;
[0045] 3. The batch controller 2 and the process control touch screen 3 can display the oil dispensing status and alarm status in real time. Among them, the process control touch screen 3 can display the loading and unloading operation process in real time, and display the grounding resistance value and alarm status in real time during use.
[0046] 4. The installation of the human infrared sensor 11 and the voice speaker 12 enables full voice broadcast of the workflow, standardizes the operation process, and ensures work safety.
[0047] This utility model integrates intelligent key management, human body static electricity release, oil tanker static grounding, and top loading and oil spill prevention warning functions into one unit. It is highly integrated with cabinet installation, equipped with a color LCD screen to display the operation process in real time, and accompanied by synchronous voice broadcast, making the oil dispensing process visible and standardized, and maximizing the automation and reliability of hazardous chemical loading and unloading operations.
