Description

[0001] SMART TIPPING SYSTEM FOR DRIVER SUPPORT AND SAFETY

[0002] Technical Field

[0003] The invention relates to a smart tipping system that provides driver support and safety for two side-tipping, three-side-tipping and rear-tipping dump trucks and two side-tipping and rear-tipping trailers using a hydraulic system.

[0004] Prior Art

[0005] The hydraulic lifting system consisting of a telescopic cylinder, pump, oil tank, directional valve, pneumatic and electro-pneumatic in-cab control valves and hydraulic installation is used in side-tipping, three-side-tipping and rear-tipping dump trucks and side-tipping and rear-tipping trailers. During the load tipping process, the pump, which is driven by the vehicle transmission through the pto gearbox, sucks the low pressure oil from the oil tank and transmits it to the directional valve by creating pressure according to the counter load resistance. The pneumatically or mechanically driven directional valve transmits the oil from the pump to the cylinder and starts the load tipping process. In another embodiment of the invention, the system pressure is regulated by means of a safety valve situated in the directional valve, while during the load tipping process it is limited by a pneumatic stop or hydraulic stop set to a predetermined safe tipping angle. In another embodiment of the invention problems such as tipping situation that may occur due to not determining the lateral slope and front slope limits, failure of the load flow and damage to the hydraulic system due to the failure to control whether the rear doors of the vehicle bodies are open or closed during the load tipping process, exposure of the hydraulic system to high pressure and damage to the system due to the failure to control the maximum load weight that the hydraulic system can lift. These problems cause serious loss of life and property.

[0006] The patent application document numbered TR2022 / 002594, which is the prior art, describes the dump vehicle safety system used to prevent accidents caused by dump vehicles hitting overpasses and bridges by leaving the tipper open while driving, overturning during unloading at an unsafe slope level, overturning while driving or exceeding the height limit as a result of overloading the vehicles. The system described in the relevant document contains hardware differences. As a result, the inadequacy of the solutions to meet the needs described above has made it necessary to develop in the relevant technical area.

[0007] Brief Description of the Invention

[0008] The invention is inspired by existing situations and aims to solve the above-mentioned problems.

[0009] The purpose of the invention is to provide a smart tipping system that provides driver support and safety for two side-tipping, three-side-tipping and rear-tipping dump trucks and two side-tipping and rear-tipping trailers using a hydraulic system.

[0010] In order to realize the above-mentioned purpose, the invention records the vehicle license plate number, company information, vehicle information, measured values during each loading and unloading, dangerous situations that occur, which are added as parameters to the visual warning unit placed in the vehicle by being controlled by electronic card software. The system works like the flight recorder of the vehicle. With the help of the static and dynamic calculations of the system processed in the electronic card software, if the lateral slope and front slope value exceeds the limit defined in the system before the load tipping starts, it gives a warning via the signal from the slope sensor in the system and the damper is not allowed to open with the signal to the air stopper valve. After the damper starts to open, if there is no signal to the position sensor placed on the rear cover of the damper, after a certain period of time, the air stopper valve is activated, the damper does not open and the rear cover is closed warning is given on the screen. Parameters such as load, pressure and speed are measured by means of the transmitter and angle sensor placed in the cylinder, the load weight is calculated by means of static and dynamic formulas defined in the electronic card software and reflected on the screen, and when the load exceeds the specified maximum threshold, the air stopper valve is activated and the damper is not allowed to open. During the unloading of the damper load, if there is a sudden value change in the front slope and lateral slope sensor due to unbalanced loading and if it exceeds the first threshold, the damper is stopped with the signal to the air stopper valve by warning the screen. If the tipping angle exceeds the specified threshold (42° - 53°), the air stopper valve will be activated with the signal from the tilt sensor placed on the vehicle chassis and the tipping process is terminated. Thanks to the smart tipping software, daily reports on the number of trips of the vehicles can be received and the location of the vehicles can be determined. If desired, the vehicle control unit can be connected online through the application downloaded to smart phones. Thanks to this connection, the desired information can be retrieved by the user and accordingly, fleet owners can increase their efficiency. Based on the stored information, the driver is notified of the periodic maintenance time of the hydraulic system.

[0029] Detailed Description of the Invention

[0030] In this detailed description, the preferred embodiments of the inventive system (1 ) are described only for a better understanding of the subject matter. The present invention relates to a smart tipping system (1 ) for driver support and safety, for use in two side-tipping, three-side-tipping and rear-tipping dump trucks (D) and two side-tipping and rear-tipping trailers (A) using a hydraulic system (HS).

[0031] The inventive system (1 ) comprises:

[0032] ❖ a visual warning unit (2) wherein the vehicle (A) license plate number, company information, vehicle (A) information, values measured during each loading and unloading are added as parameters, and that transmits to the driver the front inclination and lateral inclination values and whether these values are above the specified limit, the pressure of the hydraulic system (HS) and whether this value is above the specified limit, the active load weight of the damper (D) and whether this weight is above the specified limit, the open and closed states of the rear cover (AK), the load tipping angle that occurs during the load unloading process and whether this angle is above the specified limit and warns the driver;

[0033] ❖ an angle sensor (3) placed between the damper (D) of the vehicle (A) and the chassis (S), used to measure the lateral and front tilt angles of the damper (D) and the speed parameters of the damper (D);

[0034] ❖ a transmitter (4) used to measure the load and pressure parameters applied to the cylinder in the hydraulic system (HS) that performs the opening and closing of the damper (D);

[0035] ❖ an angle sensor (3), solenoid pneumatic valve (5) used to stop the hydraulic system (HS) in case the values received from the transmitter (4) exceed the specified limits and

[0036] ❖ an electronic control unit (6) which: o communicates data with all elements of the system (1 ) through its electronic software; o displays all the measurement data obtained to the driver of vehicle (A) via the visual warning unit (2); o generates a daily report on the number of trips of vehicles (A), determines the locations of vehicles (A), determines the periodic maintenance time of the hydraulic system (HS) and transmits the data to the driver of vehicle (A) via the visual warning unit (2); o visually warns the driver of the vehicle (A) via the visual warning unit (2) if the values measured during the opening and closing of the damper (D) are higher than the defined values; o visually warns the driver of the vehicle (A) via the visual warning unit (2) if the values measured during the opening and closing of the damper (D) are higher than the defined values; o calculates the load weight by controlling the load and pressure parameters coming to the cylinder measured by the transmitter (4) by means of static and dynamic formulas defined in the software, and prevents the damper (D) from opening by activating the solenoid pneumatic valve (5) when the load exceeds the specified maximum value; o prevents the damper (D) from opening if there is a sudden value change in the front tilt and lateral tilt angle sensor (3) due to unbalanced loading during the unloading of the damper (D) load, and if this value change exceeds the limit defined in the software, the solenoid pneumatic valve (5) is activated; and o prevents the damper (D) from opening by activating the solenoid pneumatic valve (5) if the damping angle from the angle sensor (3) exceeds the limit set in the software (e.g. 42°- 53°) (Figure 1 and Figu re 2).

[0037] The electronic control unit (6) generates daily reports on the number of trips of the vehicles (A) and determines the location of the vehicles (A) thanks to its smart damping software. Based on the stored information, the periodic maintenance time of the hydraulic system (HS) is determined by the electronic control unit (6). The data determined by the electronic control unit (6) is transferred to the visual warning unit (2).

[0038] In one embodiment of the invention, the visual warning unit (2) is in the form of a wired control display which is fixed and immovable, mounted in the vehicle (A) in a position visible and accessible to the driver.

[0039] In another embodiment of the invention, the visual warning unit (2) is in the form of a smart device, which is owned by users (e.g. fleet owners) and which is remotely connected to the electronic control unit (6) by means of software installed therein. The visual warning unit (2) in the form of a smart device enables wireless remote control of the data transmitted via the electronic control unit (6) by the user (e.g. fleet owners or vehicle (A) drivers). The remote access improves the efficiency for the fleet owners. In one embodiment of the invention, the system (1 ) comprises an auditory warning unit (7) mounted in the vehicle (A) which audibly alerts the driver of the vehicle (A) when the values measured by the electronic control unit (6) are higher than defined values.

[0040] In one embodiment of the invention, the system (1 ) comprises a position sensor (8) for determining whether the rear cover (AK) of the damper (D) is open. The solenoid pneumatic valve (5), in addition to the angle sensor (3) and transmitter (4) data, stops the hydraulic system (HS) if the values received from the position sensor (8) exceed specified thresholds. The electronic control unit (6) prevents the damper (D) from opening by activating the solenoid pneumatic valve (5) after a certain period of time if there is no signal from the position sensor (8) after the damper (D) starts to open.

[0041] By means of the position sensor (8) placed on the rear cover (AK) on the damper (D), it is checked whether the rear cover (AK) is open or not before unloading. If the rear cover (AK) is closed, the signal received from the position sensor (8) is transmitted to the solenoid pneumatic valve (5) via the electronic control unit (6). In this way, the hydraulic system (HS) is not allowed to operate. The warning that the rear cover (AK) is closed is transmitted from the visual warning unit (2) to the driver of the vehicle (A).

[0042] The front tilt and lateral tilt values of the hydraulic system (HS) are measured by means of the angle sensor (3) before the start of the unloading process in two-side tipping, three-side tipping and rear tipping tipper (D) truck and two-side tipping and rear tipping trailer (trailer) vehicles (A). The electronic control unit (6) performs a ground survey on the front tilt and lateral tilt values determined by the hydraulic system (HS) statics equations in accordance with the damper (D) geometry defined in its software. If the front tilt and lateral tilt values are above the specified threshold, the signal from the angle sensor (3) is transmitted to the visual warning unit (2) via the electronic control unit (6) and the driver of the vehicle (A) is warned. If the load tipping process is to be continued under these conditions, the solenoid pneumatic valve (5) is triggered by the electronic control unit (6) as a result of the signal from the angle sensor (3) and the hydraulic system (HS) is stopped.

[0043] All risky and normal conditions of the hydraulic system (HS) during tipping are recorded in the memory of the electronic control unit (6). The printouts of these records can be obtained from the visual warning unit (2). The transmitter (4) in the hydraulic system (HS) measures the pressure of the hydraulic system (HS). This pressure is transmitted to the visual warning unit (2) via the electronic control unit (6). The driver of vehicle (A) monitors the pressure of the hydraulic system (HS) via the visual warning unit (2). If the pressure of the hydraulic system (HS) exceeds the set limit, as a result of the signal from the transmitter (4), the electronic control unit (6) transmits a signal to the solenoid pneumatic valve (5) and stops the hydraulic system (HS).

[0044] The electronic control unit (6) calculates the load weight of the damper (D) by controlling the value received from the transmitter (4) with the help of static and dynamic formulas suitable for the damper (D) geometry defined in the software. The electronic control unit (6) transmits these values to the visual warning unit (2). The driver of vehicle (A) monitors the active load weight of the damper (D) on the visual warning unit (2).

[0045] The angle sensor (3) measures the load tipping angle during the unloading process. The electronic control unit (6) transmits the load tipping angle to the vehicle (A) driver via the visual warning unit (2). If the load tipping angle exceeds the specified threshold, the solenoid pneumatic valve (5) is warned by the electronic control unit (6) and the hydraulic system (HS) is stopped.

[0046] In all the aforementioned cases, the electronic control unit (6) ensures that the driver of the vehicle (A) is warned visually via the visual warning unit (2) and audibly via the audible warning unit (7).

[0047] All risky and normal conditions of the hydraulic system (HS) during tipping are recorded in the memory of the electronic control unit (6). These records can be printed out from the visual warning unit (2).

[0048] Thanks to the system (1 ), the number of trips of vehicles (A) stored in the memory of the electronic control unit (6) can be monitored, daily reports can be received, and the location can be determined by the owners of the vehicles (A).

[0049] Thanks to the system (1 ), the traceability of the products used in the hydraulic system (HS) is ensured and the maintenance periods are notified to the driver and the owner of the vehicle (A) via the electronic control unit (6).
