Description

Technical Field

[0001] The utility model relates to the technical field of vehicle driving monitoring, in particular to a pit avoidance system. Background Art

[0002] Currently, in some workshops, pits are opened on the ground, and vehicles sometimes pass over the pits when entering the workshops.

[0003] In the prior art, since the pits inside the workshops are generally open, there are certain blind spots in the front view when the vehicle passes over the pits. At present, it still completely relies on personal driving skills and the manual command of other on-site personnel, and there are no driving guidance and pit avoidance protection measures in the workshop, which cannot fully protect the safety of the driver and the vehicle. There is a hidden danger that the vehicle may fall into the pit, and relying on the command of on-site personnel also causes waste of labor. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pit avoidance system, which can guide the forward direction of the vehicle after it enters the workshop, monitor the driving position of the vehicle, and give an alarm when the vehicle body deviates and gets too close to the pit, so as to timely remind the vehicle driver to avoid the pit, reduce the hidden danger of the vehicle accidentally falling into the pit, and does not rely on the command of on-site personnel, with strong safety and practicability.

[0005] To achieve the above object, the utility model adopts the following technical solutions:

[0006] A pit avoidance system is arranged in a workshop, and there is a pit in the workshop. The pit avoidance system includes:

[0007] Two sets of deviation monitoring components are arranged in the workshop and are spaced along a first direction. The two sets of deviation monitoring components can respectively form light rays extending along a second direction on both sides of the pit. The light rays can be cut off when the vehicle running along the second direction above the pit is deviated. The first direction is perpendicular to the second direction;

[0008] An alarm component is communicatively connected with the two sets of deviation monitoring components;

[0009] A positioning emitter is arranged in the workshop. The positioning emitter can emit light rays and form light spots on the front windshield of the vehicle above the pit.

[0010] Preferably, the deviation monitoring component includes a deviation emitter, a receiver and a reflector. Along the second direction, the deviation emitter and the receiver are located on one side of the pit, and the reflector is located on the other side of the pit. The light rays emitted by the deviation emitter are reflected by the reflector and received by the receiver.

[0011] Preferably, the offset monitoring component includes an offset emitter and a receiver. Along the second direction, the offset emitter and the receiver are respectively located on opposite sides of the pit, and the light emitted by the offset emitter is received by the receiver.

[0012] Preferably, the positioning emitter is set as a visible light emitter.

[0013] Preferably, the positioning emitter is directly opposite to the central axis of the pit.

[0014] Preferably, a power supply is further included, and the power supply is used to supply power to the offset emitter, the receiver, and the positioning emitter.

[0015] Preferably, an inbound detection component is further included, which is arranged at the entrance of the workshop, and the inbound detection component is communicatively connected to the power supply.

[0016] Preferably, the inbound detection component is set as a photoelectric sensor.

[0017] Preferably, the alarm component includes a buzzer and / or an alarm light.

[0018] Preferably, the alarm lights are set in two groups, and the two groups of alarm lights are arranged in one-to-one correspondence with the two offset monitoring components.

[0019] Beneficial effects:

[0020] The anti-pitfall system provided by the present utility model emits light through a positioning emitter and forms a light spot on the front windshield of the vehicle above the pit, which can be observed by the driver and guide the vehicle to move forward. After the vehicle just enters the workshop, its general forward range can be maintained within a reasonable range to avoid excessive deviation of the vehicle head. In addition, two offset monitoring components are arranged in the workshop at intervals along the first direction, and the two offset monitoring components can respectively form light rays extending along the second direction on both sides of the pit. The first direction and the second direction can respectively correspond to the width direction and the running direction of the vehicle. It can be understood that the pit is located between two light rays formed by the two offset monitoring components along the first direction, and the area outside the two light rays is the safe driving area of the vehicle. When the light rays emitted by the offset monitoring components are not cut off, it indicates that the wheels are within the safe driving area, and the wheels on both sides of the vehicle will not fall into the pit. When the vehicle travels too much to one side, the wheels on the opposite side of the biased side are too close to the pit, and there is a risk that the wheels on this side will fall into the pit. At this time, the body of the vehicle will cut off the light rays on the biased side, and the alarm component will alarm, so as to timely remind the driver to pay attention to the position of the vehicle body and turn the steering wheel in the direction opposite to the biased side to adjust the forward direction of the vehicle body and reduce the deviation distance of the vehicle body, so that the vehicle body can re-enter the safe driving area, and then timely remind the vehicle driver to drive to avoid the pit, reduce the hidden danger of the vehicle accidentally falling into the pit, and does not rely on the command of on-site personnel, with strong safety and practicability.

[0036] This embodiment provides an anti-pit system. Refer to Figure 1 As shown, the anti-pit system is arranged in the workshop 5, and a pit 52 is arranged in the workshop 5.

[0037] The pit avoidance system includes a deviation monitoring component, an alarm component, and a positioning transmitter 2 disposed in the workshop 5. Among them, there are two sets of deviation monitoring components, which are disposed in the workshop 5 and arranged at intervals along the first direction. The two sets of deviation monitoring components can respectively form light rays extending along the second direction on both sides of the pit 52. The light rays can be cut off when the vehicle 6 located above the pit 52 and running along the second direction is deviated. The first direction is perpendicular to the second direction. The alarm component is communicatively connected to the two sets of deviation monitoring components. The positioning transmitter 2 can emit light rays and form light spots on the front windshield of the vehicle 6 above the pit 52.

[0038] Specifically, the alarm component is communicatively connected to the deviation monitoring component through a controller (not shown). The controller is adapted to control the alarm component to alarm when the light rays emitted by the deviation monitoring component are cut off by the deviation of the vehicle 6 located above the pit 52 and running along the second direction.

[0039] In this embodiment, the a direction and the b direction shown in the figure are the first direction and the second direction respectively. Exemplarily, the first direction and the second direction can respectively correspond to the width direction and the running direction of the vehicle.

[0040] In this embodiment, the workshop 5 is also provided with an entrance 51, and the vehicle 6 can drive into the workshop 5 through the entrance 51. In this embodiment, the pit 52 is set in a rectangular shape, and the entrance 51 is disposed opposite to the pit 52 along the second direction.

[0041] In this embodiment, by setting the positioning transmitter 2, the positioning transmitter 2 emits light rays and forms light spots on the front windshield of the vehicle 6 above the pit 52, which can be observed by the driver and guide the vehicle 6 to move forward. After the vehicle 6 just drives into the workshop 5, its general forward range can be kept within a reasonable range to avoid excessive deviation of the vehicle head. In addition, the pit 52 is located between the two light rays formed by the two deviation monitoring components along the first direction, and the area outside the two light rays is the safe driving area of the vehicle 6. When the light rays emitted by the deviation monitoring component are not cut off, it indicates that the vehicle 6 is within the safe driving area, and the wheels on both the left and right sides of the vehicle 6 will not fall into the pit 52. When the vehicle 6 travels too much to one side, the wheels on the opposite side of the biased side are too close to the pit 52, and there is a risk that the wheels on this side will fall into the pit 52. At this time, the body of the vehicle 6 will cut off the light rays on the biased side. At this time, the controller works to control the alarm component to alarm, so as to timely remind the driver to pay attention to the position of the vehicle body and turn the steering wheel in the direction opposite to the biased side to adjust the forward direction of the vehicle body, reduce the deviation distance of the vehicle body, so that the vehicle body can re-enter the safe driving area, and then timely remind the driver of the vehicle 6 to avoid the pit during driving, reduce the hidden danger of the vehicle 6 accidentally falling into the pit 52, and does not rely on on-site personnel command, with strong safety and practicability.

[0042] Exemplarily, the controller is set as a PLC controller.

[0043] As an alternative implementation, referring to Figures 1 to 3 As shown, the offset monitoring component includes an offset emitter 11, a receiver 12, and a reflector 13. Along the second direction, the offset emitter 11 and the receiver 12 are located on one side of the pit 52, and the reflector 13 is located on the other side of the pit 52. The offset emitter 11 emits light, which is reflected by the reflector 13 and received by the receiver 12. Specifically, the offset emitter 11 and the receiver 12 can be set as an integral unit. The offset emitter 11 and the receiver 12 are located on the side away from the entrance 51 along the second direction, and the reflector 13 is located on the side close to the entrance 51.

[0044] Specifically, the alarm component includes an alarm lamp 32. The controller is adapted to control the alarm lamp 32 to change color when the receiver 12 does not receive the light emitted by the corresponding offset emitter 11. Exemplarily, when the alarm lamp 32 corresponds to a left or right offset of the vehicle 6, it can be set to light two different colors, thereby reminding the driver to turn the steering wheel in the corresponding direction and adjust the forward direction of the vehicle 6 accordingly.

[0045] Exemplarily, when the vehicle 6 Figure 2 is excessively offset to the right as shown in Figure 3 , the alarm lamp 32 lights red; when the vehicle 6

[0046] is excessively offset to the left as shown in

[0047] is excessively offset to the left as shown in Figure 1 , the alarm lamp 32 lights blue. Figure 2 Specifically, in this embodiment, the alarm lamp 32 is provided in two groups, and the two groups of alarm lamps 32 are provided in one-to-one correspondence with two offset monitoring components. Specifically, the two groups of alarm lamps 32 are provided in one-to-one correspondence with two receivers 12. The controller is adapted to control the alarm lamp 32 corresponding to the receiver 12 to change color when the receiver 12 does not receive the light emitted by the corresponding offset emitter 11. Figure 3When it is too far to the left, the right wheel cuts off the light on the right side. At this time, the light emitted by the off-position emitter 11 on the right side of the figure cannot be reflected by the reflector 13 to the receiver 12. At this time, the controller controls the alarm lamp 32 of the right group to switch to red, reminding the driver to turn the steering wheel to the right in time and adjust the vehicle body to move forward to the right. When the whole vehicle body returns to the safe driving area, the vehicle body removes the occlusion of the light on the right side. At this time, the receiver 12 on the right side receives the light emitted by the corresponding off-position emitter 11 again. At this time, the controller controls the alarm lamp 32 of the right group to switch back to green, reminding the driver that the vehicle has returned to the safe driving area.

[0048] The principle and process of the controller controlling the color change of the alarm lamp 32 by receiving the signal of the receiver 12 are all prior arts and will not be elaborated here.

[0049] Specifically, the alarm component includes a buzzer 31. The controller is adapted to control the buzzer 31 to buzz when the receiver 12 does not receive the light emitted by the corresponding off-position emitter 11. Exemplarily, when the vehicle 6 is Figure 1 as shown in the safe driving area, the buzzer 31 does not buzz. When the vehicle 6 is Figure 2 too far to the right, or Figure 3 too far to the left as shown in the figure, the vehicle body occludes the light on one side, so that the receiver 12 on the corresponding side cannot receive the light. At this time, the controller controls the buzzer 31 to buzz, which can cooperate with the alarm lamp 32 to remind the driver from two sensory dimensions of vision and hearing.

[0050] The principle and process of the controller controlling the buzzer 31 to buzz by receiving the signal of the receiver 12 are all prior arts and will not be elaborated here.

[0051] As an alternative embodiment, the off-position monitoring component may not be provided with the reflector 13. Referring to Figure 4 as shown, the off-position monitoring component includes an off-position emitter 11 and a receiver 12. Along the second direction, the off-position emitter 11 and the receiver 12 are respectively located on opposite sides of the pit 52, and the light emitted by the off-position emitter 11 is received by the receiver 12. Specifically, in this embodiment, the off-position emitter 11 is located on the side far from the entrance 51 along the second direction, and the receiver 12 is located on the side close to the entrance 51.

[0052] In this embodiment, the positioning emitter 2 is directly opposite to the central axis of the pit 52, and the positioning emitter 2, the pit 52 and the entrance 51 of the workshop 5 are arranged in sequence. In this way, after the vehicle 6 just drives into the workshop 5 through the entrance 51, if the light emitted by the positioning emitter 2 projects to the middle position of the front windshield of the vehicle 6, it indicates that the general forward range of the vehicle 6 can be maintained within a reasonable range after entering the workshop 5, ensuring that the front of the vehicle is in a relatively centered position.

[0053] Exemplarily, the positioning emitter 2 is set as a visible light emitter. The visible light color can be red, green, etc.

[0054] In this embodiment, the pit avoidance system further includes a power supply (not shown), which is used to supply power to the offset emitter 11, the receiver 12, and the positioning emitter 2. Exemplarily, a distribution box is configured in the workshop 5, and a 24V regulated power supply is integrated in the distribution box. In addition, the controller is also integrated in the distribution box.

[0055] Furthermore, the pit avoidance system further includes an inbound detection component 4 disposed at the entrance 51 of the workshop 5. The inbound detection component 4 is communicatively connected to the power supply. Specifically, the inbound detection component 4 is communicatively connected to the power supply through the controller. The controller is adapted to control the power supply to supply power to the offset emitter 11 and the receiver 12 when the inbound detection component 4 detects that the vehicle 6 enters the workshop 5 through the entrance 51. Specifically, when no vehicle 6 enters the workshop 5, the offset emitter 11 and the receiver 12 can remain powered off and inoperative. When the inbound detection component 4 detects that the vehicle 6 enters the workshop 5 through the entrance 51, the inbound detection component 4 sends a signal to the controller, causing the controller to conduct the circuits of the power supply to the offset emitter 11, the receiver 12, and the positioning emitter 2, thereby enabling the power supply to supply power to the offset emitter 11, the receiver 12, and the positioning emitter 2.

[0056] Exemplarily, a relay and a terminal block are integrally arranged in the distribution box. The controller is connected to the offset emitter 11, the receiver 12, and the positioning emitter 2 through the relay and the terminal block. The power supply can supply power to the offset emitter 11, the receiver 12, and the positioning emitter 2 in sequence through the controller, the relay, and the terminal block. The controller is used to control the on-off of the relay, thereby correspondingly controlling the on-off power supply of the offset emitter 11, the receiver 12, and the positioning emitter 2.

[0057] Exemplarily, a circuit breaker is also arranged in the distribution box. The circuit breaker is used to quickly cut off the power supply when the circuit in the distribution box is abnormal, playing a role in safety protection.

[0058] Exemplarily, the inbound detection component 4 is set as a photoelectric sensor. The working principle and the using process of the photoelectric sensor are prior art and will not be elaborated here.

[0059] In this embodiment, when the vehicle 6 safely drives into a suitable position in the workshop 5 and stops, under the control of the controller, the offset emitter 11, the receiver 12, and the positioning emitter 2 will continue to be powered on and work for a period of time for monitoring and observation, and then power off after ensuring that the vehicle 6 will not move again. The monitoring and observation time is preferably set to 10 minutes.

[0060] In this embodiment, after the offset emitter 11, the receiver 12, and the positioning emitter 2 are powered off, the warehousing detector 4 will continue to be powered on to detect whether there will be any vehicles 6 driving into the workshop 5 subsequently.

[0061] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
