Fig. 1 is a schematic structural diagram illustrating a forklift safety monitoring system according to an exemplary embodiment. Fig. 2 is a control block diagram illustrating a forklift safety monitoring system in accordance with an exemplary embodiment.
As shown in fig. 1 and fig. 2, the utility model provides a forklift safety monitoring system 100, including a first gravity sensor 101, a position sensor 102, a height sensor 103 and a controller 104, the first gravity sensor 101, the position sensor 102, the height sensor 103 are all electrically connected with the controller 104.
The first gravity sensor 101 is disposed on the tines 201 of the fork 200 of the forklift for sensing the weight of the load lifted by the fork 200, generating a load weight signal S1, and transmitting the load weight signal S1 to the controller 104. The number of the first gravity sensors 101 is one or more, in this embodiment, in order to more accurately sense the weight of the goods lifted by the fork 200, a plurality of the first gravity sensors 101 are disposed on each fork tooth 201, and the plurality of the first gravity sensors 101 are uniformly arranged in a straight line along the length direction of the fork tooth 201.
The position sensor 102 is disposed on the front wall 202 of the fork 200 for sensing the cargo position of the cargo on the fork 200, generating a cargo position signal S2, and sending the cargo position signal S2 to the controller 104. In the present embodiment, the position sensor 102 may be an ultrasonic sensor, a laser sensor, or the like.
A height sensor 103 is provided on the mast 203 of the forklift for sensing the mast rise of the load being lifted by the forks 200, generating a mast rise signal S3, and sending the mast rise signal S3 to the controller 104.
The controller 104 receives the cargo weight signal S1 sent by the first gravity sensor 101, the cargo position signal S2 sent by the position sensor 102 and the gantry lifting height signal S3 sent by the height sensor 103, and then the controller 104 calculates the current rated lifting amount corresponding to the cargo position sensed by the position sensor 102 and the gantry lifting height sensed by the height sensor 103 according to a predetermined calculation formula according to the received cargo position signal S2 and gantry lifting height signal S3. The predetermined calculation formula is pre-loaded into the controller 104 in consideration of the actual influence factors of the lifting heights, the inclination angles of the forks and the like of the forklifts with different specifications on the basis of the "fork load curve". The controller 104 compares the weight of the cargo sensed by the first gravity sensor 101 with the calculated current rated lift capacity according to the received cargo weight signal S1, and when the weight of the cargo sensed by the first gravity sensor 101 exceeds the calculated current rated lift capacity, the controller 104 controls the fork 200 to stop lifting and can simultaneously control the cargo weight overload warning operation (for example, the alarm 110 described below sends a cargo weight overload warning signal and/or the display 111 displays a cargo weight overload warning signal). At this time, under the conditions of the current cargo gravity center and the cargo lifting height, the weight of the cargo which can be lifted by the forklift exceeds the upper limit, and the driver is prohibited from lifting the cargo. The alarm signal may include sound, light, images, text, or a combination thereof. The warning signal may include a picture, text, or a combination thereof.
In this embodiment, the weight of the currently lifted cargo is compared with the current rated load capacity, and it is determined whether the weight of the currently lifted cargo on the fork 200 is overloaded, rather than being compared with the rated load capacity of the forklift. Because the rated load lifting of the forklift refers to the weight of the goods which can be lifted when the center of gravity of the goods is within the center distance of the standard load lifting of the forklift, the forklift portal is vertical and is lifted to the standard lifting height of the forklift, and the center of gravity of the goods can not be ensured to be within the center distance of the standard load of the forklift when the goods are actually lifted. That is, if the load is not at the standard load center distance of the forklift, the fork 200 cannot raise the load of the rated load to the standard lift height, and if the load is still compared according to the rated load, the load may be erroneously judged as not being overweight when the load is actually overweight, and the load or the forklift may be tipped over. On the contrary, when the center of the goods is within the center distance of the standard load of the forklift, the goods are lifted to the standard lifting height, the heavier goods can be actually borne, if the goods are still compared according to the rated lifting capacity, the forklift can not be effectively utilized, and the resource waste is caused.
In this embodiment, the current rated load lifting capacity under the actual use condition is calculated according to the weight of the cargo, the position of the cargo and the lifting height of the gantry, which are measured by the first gravity sensor 101, the position sensor 102 and the height sensor 103, through a predetermined calculation formula, so that the lifting capacity of the forklift is fully utilized under the condition of ensuring safety, and the method is safe and efficient.
In one embodiment, the truck safety monitoring system 100 further includes a first angle sensor 105 disposed on the mast 203 of the truck and electrically connected to the controller 104 for sensing the angle at which the mast 203 is tilted to maintain the forks 200 level when the truck is ascending and descending, and generating and transmitting a mast tilt angle signal S4 to the controller 104.
When the forklift bears the goods to go up and down the slope, in order to ensure that the goods do not slide on the fork teeth 201 of the fork 200, the portal 203 is required to drive the fork 200 to rotate by a certain angle so as to enable the gear shaping 201 to keep horizontal, the moment changes at the moment, the inclination angle factor of the portal needs to be taken into consideration to calculate the current rated lifting load under the current condition, and therefore, in order to ensure that the rated lifting load which is more in line with the actual condition is obtained, the first angle sensor 105 can be arranged.
The controller 104 calculates the current rated load lifting amount corresponding to the mast inclination angle sensed by the first angle sensor 105, the cargo position sensed by the position sensor 102 and the mast lifting height sensed by the height sensor 103 according to the received mast inclination angle signal S4, the cargo position signal S2 and the mast lifting height signal S3; and compares the weight of the cargo sensed by the first gravity sensor 101 with the current rated lift weight according to the received cargo weight signal S1, and when the weight of the cargo exceeds the current rated lift weight, controls the fork 200 to stop lifting, and can simultaneously control the operation of cargo weight overload alarm (for example, the alarm 110 described below sends a cargo weight overload alarm signal, and/or the display 111 displays a cargo weight overload alarm signal). The alarm signal may include sound, light, images, text, or a combination thereof. The warning signal may include a picture, text, or a combination thereof.
In one embodiment, the forklift safety monitoring system 100 further includes a second angle sensor 106 disposed on a steering wheel of the forklift and electrically connected to the controller 104 for sensing a steering angle of the forklift, generating a steering angle signal S5, and transmitting the steering angle signal S5 to the controller 104. The controller 104 compares the steering angle of the forklift sensed by the second angle sensor 106 with a preset steering angle according to the received steering angle signal S5, and when the steering angle of the forklift exceeds the preset steering angle, the controller 104 controls to perform a steering angle abnormality alarm (for example, a steering angle abnormality alarm signal is sent by an alarm 110 described below, and/or a cargo weight overload alarm signal is displayed by the display 111). The preset steering angle may be preset within the controller 104. The alarm signal may include sound, light, images, text, or a combination thereof. The warning signal may include a picture, text, or a combination thereof.

When the distance to the object sensed by the distance sensor 107 is less than the preset distance, the controller 104 controls to perform an obstacle alarm operation (for example, the alarm 110 described below sends an obstacle alarm signal, and/or the display 111 displays an obstacle warning signal). The preset distance may be preset within the controller 104.
The field of vision is limited when a forklift driver drives the forklift, therefore, the distance sensor 107 is further arranged in the embodiment, when the distance of an object sensed by the distance sensor 107 is smaller than the preset distance, the driver is reminded of obstacles around through an alarm signal or a warning signal, and the situation that goods and personnel are damaged due to the fact that the forklift collides with the obstacles is avoided. In this embodiment, the preset distance may be 0.5 to 3m, and preferably the preset distance is 1 m. The alarm signal may include sound, light, image, text or a combination thereof, and the warning signal may include image, text or a combination thereof, such as "distance to attention" text or voice prompt.
In one embodiment, the forklift safety monitoring system 100 further includes a second weight sensor 108 disposed on the driver seat and electrically connected to the controller 104 for sensing the weight of the person on the driver seat and generating and sending a person weight signal S7 to the controller 104.

The preset weight may be preset within the controller 104.
In the actual use process of fork truck, the phenomenon that the driver forgets to pull the hand brake when leaving the fork truck seat temporarily exists, and the car slipping accident is easily caused. Therefore, in the embodiment, the second gravity sensor 108 is further arranged, when the driver leaves the seat, the weight of the human body sensed by the second gravity sensor 108 is smaller than the preset weight, and the controller 104 controls the electronic hand brake of the forklift to forcibly brake the forklift, so as to prevent the forklift from slipping caused by forgetting to pull the hand brake.

In one embodiment, the forklift safety monitoring system 100 further comprises an alarm 110, the alarm 110 is electrically connected to the controller 104, and when the weight of the cargo sensed by the first gravity sensor 101 exceeds the current rated lifting capacity, the controller 104 controls the alarm 110 to send a cargo weight overload alarm signal; when the steering angle of the forklift sensed by the second angle sensor 106 exceeds the preset steering angle, the controller 104 controls the alarm 110 to send out a steering angle abnormity alarm signal; when the distance of the object sensed by the distance sensor 107 is less than the preset distance, the controller 104 controls the alarm 110 to send an obstacle alarm signal.
