Based on this, an embodiment of the present application provides a distance security method for a loading dock, and referring to fig. 1, fig. 1 is a schematic flow diagram of a first embodiment of the distance security method for a loading dock according to the present application.

In this embodiment, the distance security method of the loading dock is applied to loading dock equipment, and the loading dock equipment includes: the device comprises a roller shutter door 1, a distance detection device 2, a display device 3, a roller shutter door signal sensing device 4 and a dock bridge 5, wherein the distance detection device is arranged below the outer side of the roller shutter door; the method comprises the steps of S10 to S20:

Step S10, when the distance detection equipment detects that the first distance between the truck and the distance detection equipment is smaller than or equal to a preset distance threshold value, the first distance is displayed through the display equipment, and the rolling door is controlled to be electrified and started;

in this embodiment, please refer to fig. 2 and 3, fig. 2 is a schematic diagram of an outer side structure of the loading dock of the present application, fig. 3 is a schematic diagram of an inner side structure of the loading dock of the present application, a rolling door signal sensing device 4 is disposed above a rolling door 1, a distance detecting device 2 is disposed below the rolling door, a correlation sensing grating 9 is disposed on the left and right sides of the rolling door, a dock bridge 5 is disposed below the rolling door 1, and a display device 3 may be disposed on a wall at a side edge of the rolling door and above the rolling door at an inner side of the rolling door, so long as the rolling door is in a position easily observed by a truck driver and personnel inside the dock.

In this embodiment, the distance detecting device is an instrument or tool specifically designed to measure the distance between the object and the detecting device. Such devices are widely used in a variety of fields, such as automation control, security systems, robotics, logistics management, aerospace, and automotive industries.

Distance detection devices typically implement distance measurement based on different physical principles and techniques, several common techniques including:

An ultrasonic sensor: calculating a distance by transmitting an acoustic pulse and receiving an echo using a propagation characteristic of the acoustic wave; the method is suitable for short-distance measurement and is commonly used in scenes such as reversing radar, liquid level measurement and the like.

Laser sensor: ranging using a laser beam, determining a distance by calculating a time difference between the laser emission and the reflected signal; the method is applied to occasions requiring high precision, such as building construction, mapping, robot positioning and the like.

An infrared sensor: measuring distance by emitting infrared light and receiving the reflected signal; suitable for short-range and low-cost applications such as proximity switches, automatic door control, etc.

Radar sensor: including microwave radar and millimeter wave radar, measuring distance by transmitting electromagnetic waves and receiving reflected signals; the method is suitable for detecting long-distance and high-speed moving objects, such as an automobile anti-collision system, weather detection and the like.

Time of flight (ToF, timeofFlight) sensor: emitting a continuous or pulsed light signal and measuring the distance by calculating the time from the emission to the return of the light; the method is suitable for accurate measurement of short to medium distances, such as face recognition, 3D scanning and the like of smart phones.

Different devices have certain advantages and limitations, and in practical applications, one or more sensors described above may be used as the distance detection device according to practical situations.

Dock axles, also known as dock platforms, are devices used to connect a boxcar to a loading dock, and are intended to provide a safe and stable transition platform for loading and unloading goods from a truck to a warehouse or from a warehouse. The design of the dock bridge solves the problem of inconvenient loading and unloading between the truck carriage and the wharf due to the height difference and the gap, improves the loading and unloading efficiency, and reduces the labor intensity of workers and the risk of cargo damage.

In this embodiment, when a truck is backed up close to the unloading dock, if the distance detection device detects that the first distance between the vehicle and the distance detection device (corresponding to the distance between the vehicle and the loading dock) is smaller than or equal to a preset distance threshold, this will be regarded as the vehicle has reached a preset parking position, wherein the distance threshold may be set by a technician according to the actual application. At this time, the distance detecting device 2 will send out a signal which will be received by the rolling door signal sensing means 4 and the display device 3, and then the display device will inform the driver that the vehicle has been parked correctly by showing the first distance, and at the same time alert the surrounding staff to the safety, and immediately thereafter the power supply of the rolling door 1 will be turned on, allowing it to start to rise.

In one possible embodiment, the distance detection device includes: a plurality of distance detectors, each of which is uniformly arranged under the roll-up door; before the step S10, the method may further include steps a10 to a20:

Step a10, for each of the distance detectors, detecting a second distance between the truck and the distance detector by the distance detector;

In this embodiment, since the truck has a certain width, the distance between the whole vehicle and the loading dock cannot be detected well by one distance detector, and therefore, a plurality of distance detectors can be uniformly arranged in the horizontal direction for detection.

In this embodiment, referring to fig. 4, fig. 4 is a scene diagram related to an embodiment of a distance security method for a loading dock according to the present application, and as shown in fig. 4, a distance detecting device 2 under a roller shutter door includes a plurality of distance detectors 21, each of which detects a distance of a truck to obtain a plurality of second distances.

And step A20, when the smallest target second distance in the second distances is smaller than or equal to the distance threshold value, judging that the first distance between the truck and the distance detection equipment is smaller than or equal to the distance threshold value.

In this embodiment, since it is difficult for the vehicle to be perfectly parallel to the loading dock in practice, the value of the distance measured by each distance detector is not exactly the same, and the smallest measured value represents the smallest distance between the truck and the loading dock, and the threshold value determination by the smallest distance can avoid the truck from colliding with the loading dock.

As an example, as shown in fig. 4, three distance detectors are uniformly arranged under the rolling door, and when the truck is not completely parallel to the unloading dock, the distances measured by the three distance detectors are not the same, the second distance measured by the right distance detector is the smallest, and the left distance is the largest, so that when the second distance measured by the rightmost distance detector is less than or equal to the preset threshold, the first distance is determined to be less than or equal to the distance threshold.

Further, in one possible implementation, the display device includes: a display screen and a speaker; the first distance includes: each of the second distances; the step of displaying the first distance through the display device in the step S10 may include steps S101 to S103:

step S101, displaying the second distance of the target by the display device through a first color;

step S102, displaying the second distances except the target second distance in the second distances by using a second color through the display device, wherein the wavelength of the first color is larger than that of the second color;

Step S103, outputting a voice prompt for broadcasting the second distance of the target through the loudspeaker.

In this embodiment, since the conspicuity degree of the color is related to the wavelength of the different visible light, the wavelength of the first color is set to be larger than the wavelength of the second color, so that the value of the minimum target second distance is more conspicuous. As an example, in each visible light, the wavelengths are sequentially violet, blue, cyan, green, yellow, orange, and red from small to large, and thus, the target second distance may be displayed in red, and the measured second distances other than the target second distance may be displayed in green.

In this embodiment, after the second distances are acquired by the distance detectors, in the real device, in order to alert the driver of the current distance, the smallest target second distance in the second distances may be represented by different colors, then other second distances are displayed by using other colors, and a voice prompt of the target second distance is broadcast in real time through a speaker on the display device, and as an example, the content of the voice may be "10 cm of the current distance".

In addition, in order to enable a driver to adjust the vehicle body according to the displayed content, the second distances can be sequentially displayed on the display device according to the sequence of the distance detection devices, the driver can intuitively see which side is larger in distance, and the second distances detected by the left side distance detector and the second distances detected by the right side distance detector can be respectively displayed on the left side and the right side of the roller shutter door by adopting two display devices, so that the convenience degree of observation is further improved.

Further, in a possible embodiment, after the step of controlling the rolling door to be powered on in the step S10, the method may further include steps B10 to B30:

Step B10, after receiving a roller shutter door control upward movement instruction, driving a first control motor of the roller shutter door to work;

in this embodiment, the roller shutter door may be controlled to be lifted by opening and closing or by remote control, the remote control may be disposed on a key of the roller shutter door, and a key placement portion 8 may be disposed on an inner side of the dock apparatus to store the key of the roller shutter door, so as to avoid loss.

In this embodiment, the system receives an instruction from the rolling door signal sensing device, which instructs the first control motor to start operating to drive the rolling door to move upward.

Step B20, driving the rolling shutter door to move upwards through the control motor;

In this embodiment, the first control motor starts to operate, and drives the roller of the roller shutter door to rotate through a transmission mechanism (such as a chain, a belt or a direct gear connection), so that the roller shutter door moves upwards along the track.

And B30, when the rolling door moves upwards to the first upper limit position, triggering a limit switch of the rolling door and the rolling door signal sensing device, and switching off the power of the first control motor to stop the rolling door from moving upwards.

In this embodiment, when the rolling door moves to the preset first upper limit position, the limit switch and the rolling door signal sensing device will be triggered, and once the rolling door is detected to reach the upper limit position, the system will immediately cut off the power supply of the first control motor to stop the operation of the first control motor, thereby preventing the rolling door from moving up excessively and avoiding possible damage or safety risk.

The above-described steps ensure that the roller door is safely and accurately opened to the desired position, ready for subsequent dock leveler operations and cargo handling operations, and in this way, the system effectively controls the movement of the roller shutter door, avoids potential safety hazards caused by misoperation or mechanical faults, and improves the efficiency and the safety of the whole loading and unloading operation.

And step S20, when the roller shutter door is detected to rise to a preset first upper limit position by the roller shutter door signal sensing device, controlling the dock leveler to be electrified and started.

In this embodiment, when the roller shutter door 1 continues to rise and reaches the preset first upper limit position, the roller shutter door signal sensing device 4 will again detect the change, at this time, a signal will be transmitted to the control system of the dock bridge 5, triggering the dock bridge to be powered on and ready to start, which means that when the roller shutter door is fully opened, the dock bridge will not be activated until enough open space is provided for loading and unloading operations, connecting the truck tail with the dock platform, and providing a safe and stable transition platform for loading and unloading operations.

In a possible embodiment, in the step S20, the step of controlling the dock leveler to be powered on may include steps S201 to S202:

step S201, controlling the relay of the dock leveler to be conducted, and electrifying a second control motor of the dock leveler;

In this embodiment, the system is closed by a relay in the control circuit, which is an electromagnetic switch, and when the coil is activated, the contact is closed or opened, in this case, the closing of the relay is to make the current flow through the second control motor of the dock bridge, and after the relay is closed, the second control motor starts to receive the electric power, so as to start, and the motor is responsible for driving the lifting and telescoping actions of the dock bridge, so as to dock with the bottom of the parked wagon carriage, so as to form a stable and safe transition platform for loading and unloading cargoes.

Step S202, an indicator lamp controlling a control linkage switch of the dock leveler is always on.

In this embodiment, once the second control motor of the dock leveler is powered on and starts to work, the system keeps the indicator light on the dock leveler control linkage switch 6 in a normally-on state, the dock leveler control linkage switch is a switch for controlling the dock leveler to lift, and the technician can be prompted to place the dock leveler in an operable state by turning on the indicator light.

Through the steps, the system ensures that the dock leveler can be accurately and timely started and is ready after the rolling shutter door is completely opened, creates a safe environment for subsequent cargo handling work, and meanwhile, the use of the indicator lamp enhances the visual management on site and improves the operation transparency and safety.

Further, in a possible embodiment, after the step of controlling the dock leveler to be powered on in the step S20, the method may further include steps C10 to C20:

Step C10, driving the second control motor to work according to the control instruction output by the control linkage switch;

in this embodiment, the control linkage switch receives an operation command, the command is based on an operator's action or a preset program in the automation system, and the second control motor starts working after receiving the command, and drives the dock leveler to perform necessary actions, such as lifting or extending, so as to seamlessly dock with the bottom of the parked wagon compartment, thereby providing a stable transition platform for loading and unloading operations.

And step C20, when the dock leveler runs to a preset second upper limit position, the limit switch of the dock leveler is triggered, and the second control motor is powered off, so that the dock leveler stops running.

In this embodiment, when the dock leveler moves to the preset second upper limit position, the limit switches are triggered, and these switches are usually located on the mechanical structure of the dock leveler to detect and control the maximum travel of the dock leveler, so as to prevent overload or exceeding the safety range.

As an example, when a truck approaches the loading dock and is docked in place, the distance detection device detects that the distance of the truck to the loading dock is less than or equal to the distance threshold. At this time, the distance detecting device is triggered, the system immediately responds, and after receiving the trigger signal of the distance detecting device, the system immediately activates the display device, and the display device displays the detected second distance and plays a preset warning audio to remind the driver and surrounding personnel of paying attention. Meanwhile, a control switch of the system for controlling the rolling shutter door is turned on, a first control motor starts to be electrified and is ready for lifting the rolling shutter door, then the system receives a rolling shutter door control upward movement instruction (or a preset instruction in an automatic program) from an operator, the first control motor is started to drive the rolling shutter door to move upward, when the rolling shutter door reaches a preset first upper limit position, a limit switch and a signal sensing device of the rolling shutter door are triggered, the first control motor is automatically powered off, the rolling shutter door stops to move upward, a relay of the system for controlling the dock bridge is turned on while the rolling shutter door is completely opened, a second control motor is electrified, an indicator lamp of a control linkage switch of the dock bridge is normally on and indicates that the dock bridge is ready for use, then the second control motor is started according to the control instruction and drives the dock bridge to move to a preset second upper limit position, and when the rolling shutter door reaches the preset first upper limit position, the second control motor is powered off, the dock bridge stops to move, and goods between a goods vehicle and a warehouse are kept at a correct position for loading and unloading.

Through the steps, the dock leveler can be accurately positioned at a proper position, so that the high-efficiency operation of loading and unloading is ensured, the safety of operators is ensured, unnecessary risks are avoided, the importance of automation and safety control is reflected by the steps, and the dock leveler is an important component of an intelligent safety precaution system in the aspect of improving the safety and efficiency of loading and unloading dock operation.

In the third embodiment of the present application, the same or similar content as the first and/or second embodiments of the present application may be referred to the above description, and will not be repeated. On this basis, the loading dock apparatus includes: an emergency stop button; the method may further include steps D10 to D20:

Step D10, when the emergency stop button is detected to be triggered, generating an emergency stop instruction;

in this embodiment, an emergency stop button is installed at a significant location on the loading dock, and when an operator or other field personnel finds any potential security threat, such as equipment abnormality, personnel injury or other emergency condition, the button may be immediately pressed, and upon pressing the button, the system will immediately generate an emergency stop command that will be quickly transmitted to the control system.

And step D20, responding to the emergency stop instruction, and controlling the first control motor of the roller shutter door and the second control motor of the dock shaft to be powered off.

In this embodiment, after receiving the emergency stop command, the system will immediately cut off the power to the roller shutter door control motor, so that the roller shutter door stops any movement, whether it is being opened or closed, and likewise, the control motor of the dock bridge will also be cut off, ensuring that the dock bridge immediately stops any action, avoiding further danger.

As an example, in a dock equipped with an intelligent security system intended to ensure the safety of the operators and the normal operation of the equipment, this system comprises the components of a roller shutter door, a dock bridge, a distance detection device, a display device, a roller shutter door signal sensing device, etc., and a key safety measure emergency stop button, this series of quick response measures being intended to minimize the injury or loss caused by the emergency situation.
