Detailed Description
For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
The inventor finds that when the container in the related technology is monitored, the condition of the internal goods and whether the container is full or not can be watched by additionally installing the camera; or whether the external environment is changed is observed, so that whether the container is spatially changed is judged to judge whether the container is overturned or moved.
In the related art, when weighing, the design of a weighing scheme is realized by designing an independent weight lifting structure and increasing a pressure sensor, and the main purpose is to reduce buffering, weight increase and the like, and no related scheme for weighing vehicles with weight changes is adopted.
From the above, the solution in the related art separately processes the condition monitoring and the weight monitoring in the container, and installs the corresponding sensor on the designed structure to perform the condition monitoring and the weight measurement, which requires high investment cost, long development period, and can not fundamentally solve the complex task of repeated weighing.
In addition, before loading, a person is required to manually open the cargo box door, then loading is carried out, after loading is finished, the person is required to manually close the door, and if the loaded vehicle is still not overloaded, the loading is carried out only once. If it is overloaded without being filled, which is not detected in real time, the cargo must be re-disassembled and re-weighed until it is not overloaded.
In view of the above-mentioned shortcomings, embodiments of the present application can achieve:
1) Automatic loading: the rear part of the vehicle is monitored to judge whether goods enter the container, if so, the container door is automatically opened, and after the goods are sent in, the container door is automatically closed.
2) And (3) loading degree monitoring: it is possible to monitor whether the interior of the container is filled with cargo.
3) Load condition monitoring: whether the vehicle is fully loaded can be judged by the height change of the infrared sensor.
The following describes in detail the technical solutions provided by the embodiments of the present application with reference to the accompanying drawings.
An embodiment of the present application provides a loading system, as shown in fig. 1, and provides a schematic structural diagram of the loading system in the embodiment of the present application, where the system includes: a first sensor 200 disposed at the bottom of the cargo box, the first sensor comprising at least two; a second sensor 100 disposed on the top of the interior of the cargo box, the second sensor comprising at least one; a third sensor 300 disposed at the bottom of the outside of the cargo box, the third sensor comprising at least two; the first sensor 200, the second sensor 100, and the third sensor 300 are electrically connected to a vehicle ECU, respectively; after the vehicle is powered on, when a target approaches and stays at the cargo box door, the cargo box door is controlled to be opened through the third sensor 300; recording the height change of the container relative to the ground by the third sensor 300, and judging whether the goods in the container are overloaded or not; and detecting the height change of the goods in the container by the first sensor 200 and the second sensor 100, and judging whether the goods in the container are fully loaded.
The first sensor 200 disposed at the bottom of the interior of the cargo box may be disposed at the bottom angle of the a-plane in the cargo box, such that it may be detected whether the cargo is placed innermost in the cargo box. With at least two of the first sensors 200, the base angle can be detected separately. A second sensor 100 disposed on top of the interior of the cargo box may be deployed on top of the B-side of the cargo box so as to detect whether the height of the cargo in the cargo box exceeds a calibrated value at the initial state. The use of at least one of the second sensors 100 can detect the relative distance of the cargo from the top of the cargo box. A third sensor 300 disposed at the bottom of the outside of the cargo box may be deployed outside the cargo box near the middle of the tail of the cargo box. With at least two of the third sensors 300, it is possible to detect whether or not an object is approaching, respectively.
It should be noted that the first sensor 200, the third sensor 300, and the second sensor 100 may be the same type of sensor or different types of sensors, which are not specifically limited in the embodiments of the present application.
It can be understood that the sensor needs to start working after the vehicle is electrified, and an initial state can be obtained after the vehicle is electrified, and the initial state can be used as a judging basis for judging whether the goods are fully loaded or overloaded afterwards.
In particular, after the vehicle is powered on, the third sensor 300 detects that the object approaches and stays at the cargo box door, and controls to open the cargo box door. That is, the third sensor 300 is added to the cargo box door to automatically open and close the cargo box door. Since the third sensor 300 is already electrically connected to the vehicle ECU, the opening/closing door control of the cargo box can be achieved by the vehicle ECU.
After the vehicle is powered on, the third sensor 300 can also record the height change of the cargo box relative to the ground, so as to judge whether the cargo in the cargo box is overloaded. That is, when the vehicle is powered on for the first time, relevant state information (such as a frame, a leaf spring, a tire, etc.) affecting the height change is collected, a change curve of the simulated height and weight is calculated with the height of the third sensor 300 itself at the time of empty as an origin, and a height limit value is preset according to the full load weight.
After the vehicle is powered on, the first sensor 200 and the second sensor 100 detect the height change of the cargo in the cargo box, and determine whether the cargo in the cargo box is fully loaded. The loaded cargo packages are in different states, so that no-load calibration is performed before loading. And judging whether the cargo is fully loaded according to the calibration result.
It should be noted that, in the above process, after the sensor is returned to the vehicle ECU, a simple logic judgment is performed, so that a corresponding control response can be performed in the vehicle ECU, and the improvement of the algorithm or software is not involved, and in the embodiment of the present application, the improvement of the connection relationship of hardware is protected.
As shown in fig. 2, the determination of the overload condition will be specifically described by taking the first sensor 200 and the second sensor 100 as optical sensors.
When the vehicle (whole vehicle) is electrified for the first time, relevant state information (such as a frame, a plate spring, a tire and the like) influencing the height change is collected, the height of a light sensor when an empty vehicle is empty is taken as an origin, a change curve of the simulated height and the weight is calculated, and a height limit value is preset according to the full-load weight.
With continued reference to fig. 2, when the vehicle (whole vehicle) is in an empty state, the height of the light sensor 1 is H, and when the vehicle is in a full state, the height of the light sensor 2 is H.
As the loaded weight is gradually increased, the whole vehicle load is continuously increased, the height of the vehicle is continuously reduced, and finally the vehicle is reduced to H from the height H of 1; when the light sensors are connected to the central control ECU, the ECU continuously records the descending height change value of 1 along with the increase of the weight when the light sensors are electrified for the first time, and the finally determined height change curve is shown in fig. 3, that is, if h (maximum load) is reached, the current cargo can be prompted by voice to reach the maximum load and can not be loaded any more. Or the current cargo reaches the maximum load through the central control, and the loading can not be carried out any more.
The overload judging process combines the light sensor, and simultaneously realizes the functions of loading and weight judgment without manual intervention.
As shown in fig. 4, the judgment of the full state will be specifically described, and the second sensor 100 will be described as an example of the photosensor.
Since the states of the loaded cargo packages are different in different scenes, the following work is required before loading: before loading a container, the size measurement is needed at the position of the light sensor 1, the light sensor is fixed to pass through 1 from bottom to top, so that the height of the container is measured, at the moment, the ECU of the light sensor needs to judge that a plurality of identical containers can be loaded in the vertical direction at most, the vertical distance h' from the B surface when the container is full is calculated, the theta value is further determined, and the specific calculation formula is as follows:
tanθ＝a/h'
θ＝arc tana/h'
the loaded real-time theta 'can be judged by the currently set theta value, and when theta' > theta, the current space is considered to be full, and at the moment, the voice prompt is carried out: the goods are filled up, please stop loading; and θ' =θ, then loading is considered to be continued.
After that, after loading is completed, if there is no loading operation within 1min, voice prompt: the containers are closed, please move away, and then the container door is closed.
It should be noted that, the check needs to be performed at each loading, and when the container height is detected to be the same, the calculation is not needed, and the corresponding saved value is directly called.
The full-load judging process combines the light sensor, and simultaneously realizes the functions of loading and weight judgment without manual intervention.
By the above system, by electrically connecting the first sensor 200, the second sensor 100 and the third sensor 300 to the vehicle ECU, respectively, and disposing them inside and outside the cargo box, respectively, it is possible to control the cargo box door to be opened when the target approaches and stays at the cargo box door, detected by the third sensor 300 after the vehicle is powered on; recording the height change of the container relative to the ground by the third sensor 300, and judging whether the goods in the container are overloaded or not; and detecting the height change of the goods in the container by the first sensor 200 and the second sensor 100, and judging whether the goods in the container are fully loaded.
In one embodiment of the present application, the detection angle of the second sensor 100 is adjustable, and the detection angle of the first sensor is fixed.
In particular, the second sensor 100 may be adjusted to different conditions of cargo placement within the cargo box, taking into account the different functions of the sensors. Similarly, the first sensor 200 may be configured to be fixed and non-adjustable to relatively accurately determine the stacking height of the cargo within the cargo box.
In one embodiment of the present application, the first sensor 200 is disposed at the bottom of the container and away from the cargo box door, and the second sensor is disposed at the top center position of the container.
The first sensor 200 is disposed at the bottom of the container and away from the door of the container, and the second sensor 100 is disposed at the top center of the container, thereby facilitating detection.
In one embodiment of the present application, the third sensor 300 is disposed in a closed position proximate the cargo box door.
The third sensor 300 may detect when a target approaches and transmit to the vehicle ECU electronic control unit, thereby judging whether to open or close the cargo box door through the vehicle EUC electronic control unit.
The third sensor 300 will be described by taking a photosensitive sensor as an example:
when the vehicle is in specific implementation, the whole vehicle is electrified, the light sensing sensor works, and whether moving goods or people are close to the rear of the vehicle is detected: when the demand is to open the cargo box door, the cargo or the person needs to pass from left to right in front of the sensor, and finally stops in front of the sensor as a judgment standard; if not, the container door is not actively opened; if so, judging again whether the goods stay at the same position for more than 10 seconds, and if not, the container door is not automatically opened. If yes, a voice prompt is needed: "the container door is about to open, please get away". Meanwhile, in the cab, the driver can obtain synchronous information from the central control without getting off.
In one embodiment of the present application, the system further comprises a voice prompt (not shown) connected to the vehicle ECU.
As described above, the system further includes a voice prompt device when voice prompt is required, and the voice prompt device is connected with the vehicle ECU, so that unified control can be performed by the vehicle ECU.
In one embodiment of the present application, the voice prompt device issues an alarm when the cargo in the cargo box is overloaded; the voice prompt device gives an alarm when the goods in the container are fully loaded; the voice prompt device gives a prompt when a target approaches and stays at the cargo box door.
The voice prompt may be used in a variety of situations, such as when the cargo in the cargo box is overloaded. For another example, an alarm may be raised when the cargo in the cargo box is full. A prompt may also be issued when a target approaches and rests on the cargo box door.
In one embodiment of the present application, the cargo in the cargo box is preloaded with the same size of box.
In order to reduce the difference judgment of the full condition of the container, the container body with the same size is adopted to load the cargoes in the container in advance during loading.
In one embodiment of the present application, when the vehicle is first powered on, an initial state of the cargo box when empty is detected by the first sensor and the second sensor.
The initial condition of the container when empty may be the height of the container when empty, and the height of the cargo in the container when full, or the angular offset from the sensor.
In one embodiment of the present application, the first sensor, the second sensor, and the third sensor each employ a light sensor.
The light sensor is adopted to meet the detection requirement in the container, and compared with a visual sensor or a gravity sensor, the sensor is simpler to deploy, and meanwhile, the relative error is smaller.
