Description

Technical Field

[0001] This invention belongs to the field of power plant mechanical facilities technology, and in particular relates to an online vehicle information detection and identification system. Background Technology

[0002] Currently, railway transportation remains the primary mode of coal transport in my country, accounting for approximately 90% of the nation's coal shipments. Analysis of recent years' data shows that railway coal transport has become the leading mode of freight transport, and the total volume continues to rise annually. To adapt to the mixed train sets of the national railway system, multi-functional tippers have become the preferred choice for major coal-consuming enterprises, making the study of reducing the unloading time of multi-functional tippers a widely applicable research topic. After coal is transported by rail to thermal power plants, it needs to be unloaded by tippers. For example, multi-functional tippers can handle 60T, 70T, general-purpose open wagons, C80 type, and C80B type open wagons, with a standard unloading time of 4 hours for a 5000-ton train. Due to its compatibility with unloading vehicles, the multi-functional tipper's transfer platform is designed for three open wagons (primarily accommodating three C80 coupled open wagons), therefore, the round-trip distance of the air conditioning unit is the same as that of three open wagons. When unloading a single open wagon, the transfer platform and air conditioning unit must also leave space for three open wagons according to the system procedure, thus wasting a lot of unloading time. This can easily cause unloading to exceed the time limit, seriously affecting the unit's fuel supply and thus affecting safe, stable, and economical operation. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the deficiencies in the prior art and proposes an online vehicle information detection identification system.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0005] An online vehicle information detection system includes a detection unit that combines the length and parking position of a single open wagon and the length and parking position of a three-section open wagon. Each detection unit includes a wagon position sensor, a rollback sensor, and a physical anti-rollback device. The wagon position sensor, rollback sensor, and physical anti-rollback device are all connected to a control unit. The wagon position sensor detects the wagon position and feeds back the vehicle type information to the control unit. The control unit then controls the air conditioner to move to the wagon position and controls the tipper to perform actions. When the rollback sensor detects that the vehicle is rolling, it feeds back the rollback signal directly to the control unit. The control unit then sends a command to stop the transfer platform and the air conditioning system, and simultaneously controls the physical anti-rollback device to brake.

[0006] Furthermore, both the carriage position sensor and the slippage sensor include proximity switches.

[0007] Furthermore, the physical anti-slip device includes a hairline anti-slip device.

[0008] Furthermore, the vehicle transfer platform includes a vehicle frame, a two-way vehicle positioning device, a limiting device, a pushing device, and a traveling device.

[0009] Furthermore, the transfer platform also includes hydraulic buffers arranged on both sides of the vehicle frame.

[0010] Furthermore, the physical anti-slip device is linked to the vehicle relocation platform for control.

[0011] Furthermore, the control unit includes a PLC controller.

[0012] Compared with existing technologies, the present invention has the following advantages:

[0013] The information identification system provided by this invention sets up a detection unit for each of the single-section and three-section open wagons. Under safe conditions, it saves the travel distance and time of the air conditioner. It interlocks the air conditioner position information and the vehicle position information of the transfer platform with the tipper unloading operating system. Once the air conditioner position information is incorrect or the transfer platform slips, the tipper system can be stopped, effectively preventing the slipping vehicle from colliding with the air conditioner during the stop and avoiding unloading accidents.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0019] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] An online vehicle information detection and identification system, such as Figure 1 As shown, a detection unit is set up for both single-section open wagons and three-section open wagons, combining their lengths and parking positions. Each detection unit includes a wagon position sensor, a slippage sensor, and a physical anti-slip device. All three are connected to a control unit. The wagon position sensor detects the wagon's position and feeds back the wagon type information to the control unit. The control unit then moves the air conditioner to the wagon's position and controls the tipper to perform its actions. When the slippage sensor detects slippage, it directly feeds back the slippage signal to the control unit, which then sends a command to stop the transfer platform and the air conditioning system, while simultaneously braking the physical anti-slip device. When unloading a single open wagon, the air conditioner does not need to return to the endpoint; it stops when it reaches the position on the track that matches the wagon. The transfer platform is equipped with wagon position sensors and physical anti-slip devices to accurately detect the wagon's position, prevent slippage accidents, and prevent collisions between the open wagon and the air conditioner boom, ensuring high safety.

[0021] Both the car position sensor and the slippage sensor include proximity switches. The physical anti-slip device includes a departure / arrival line anti-slip device. The physical anti-slip device is linked to the transfer platform for control; typically, one of them operates while the other stops. In the event of slippage in a single open car, the system is linked to ensure safe unloading. The control unit includes a PLC controller. The transfer platform includes a frame, a bidirectional vehicle positioning device, a limit device, a pushing device, and a traveling device. Additionally, the transfer platform includes hydraulic buffers arranged on both sides of the frame.

[0022] In an optional embodiment, a safe area is located near the transfer platform, and a deceleration sensing device and a stop sensing device are installed in this safe area. Both the deceleration sensing device and the stop sensing device include infrared detection sensors, which can effectively measure the position information of the open wagon and even if the deceleration device and the stop device on the control line are working.

[0023] By implementing automatic control of the mid-stop of the car transfer platform and air conditioning system, the unloading efficiency is improved and the unloading time is reduced. At the same time, the equipment utilization rate of the entire car tipper system is greatly improved, reducing the unloading time of a 5,000-ton train to 3.5 hours. This fundamentally avoids the overtime assessment of the car tipper, which is conducive to energy conservation and consumption reduction. Taking a single train of 50 open cars as an example, the assessment for 1 hour of overtime is 5.7 yuan * 50 cars * 1 hour = 285 yuan. With one train per day, the annual cost savings are 104,000 yuan.

[0024] The information identification system provided by this invention sets up a detection unit for each of the single-section and three-section open wagons. Under safe conditions, it saves the travel distance and time of the air conditioner. It interlocks the air conditioner position information and the vehicle position information of the transfer platform with the tipper unloading operating system. Once the air conditioner position information is incorrect or the transfer platform slips, the tipper system can be stopped, effectively preventing the slipping vehicle from colliding with the air conditioner during the stop and avoiding unloading accidents.

[0025] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
