2. The vehicle carrying plate entering and exiting the vehicle layer only needs to move transversely.
3. Except the rest layers of the entering and exiting vehicle layers, the vehicle carrying plates need to be lifted or have both lifting action and transverse movement action, and the vehicle carrying plates are called as lifting vehicle carrying plates. Under the condition of no ambiguity, the 'lifting vehicle carrying plate' is simply called as the 'vehicle carrying plate' in the specification.
4. At any moment, only one of the vehicle carrying plates of a certain floor is allowed to ascend or descend, and the normal operation completion position of the ascending or descending vehicle carrying plate is the normal standing height position of the floor or the normal standing height position of the entering or exiting vehicle floor.
5. The vehicle carrying plate higher than the vehicle entering and exiting layer rises to the normal standing height position of the layer or the vehicle carrying plate lower than the vehicle entering and exiting layer rises to the normal standing height position of the vehicle entering and exiting layer, namely the vehicle carrying plate rises in place and is in a normal rising state; and after the vehicle carrying plate higher than the vehicle entering and exiting layer rises to the normal standing height position of the layer or the vehicle carrying plate lower than the vehicle entering and exiting layer rises to the normal standing height position of the vehicle entering and exiting layer, if the vehicle carrying plate continues to rise and reaches the limit height position, the vehicle carrying plate is called as a rising overrun state and is in a rising fault state.
6. Each lifting vehicle carrying plate needs to be lifted to a proper position for detection and lifted to exceed the limit for detection.
In order to realize the ascending detection of the vehicle carrying plates, in the prior art, an ascending in-place detection device and an ascending over-limit detection device are respectively arranged on each ascending and descending vehicle carrying plate to jointly form a vehicle carrying plate ascending detection system, and the system is relatively complex and tedious in wiring and control; meanwhile, the related detection device usually uses components and parts which need mechanical action and contacts, such as a rocker switch, and has the defects of low detection precision, easy damage, low reliability and the like.
The invention aims to overcome the defects of the prior art, designs a vehicle carrying plate rising detection device adopting correlation type photoelectric detection, only needs to install one set of lifting in-place detection device and one set of lifting overrun detection device on each layer, is used for replacing the prior complex vehicle carrying plate rising detection system consisting of each vehicle carrying plate and respectively installing one set of lifting in-place detection device and one set of lifting overrun detection device, and has the advantages of few detection components, simple control process, high reliability and low cost.
In order to achieve the purpose, the basic technical scheme of the ascending detection device of the vehicle carrying plate is characterized in that: the vehicle carrying plate is a lifting vehicle carrying plate with lifting and descending functions in the lifting and transverse moving parking equipment; the rise detection comprises in-place detection and overrun detection; the in-place refers to that the vehicle carrying plate rises to a preset height position where the layer is normally placed; the overrun refers to that the vehicle carrying plate rises to a preset height position where the layer exceeds the overrun limit.
The ascending detection device comprises an in-place detection device, an overrun detection device and a light barrier.
The in-place detection device is used for detecting that the vehicle carrying plates ascend in place and is a correlation photoelectric switch, one set of the in-place detection device is arranged on each layer except for the vehicle entering and exiting layer, the in-place detection device is arranged at the rear position of the equipment rack and comprises a transmitter and a matched receiver, and the installation height is higher than the ascending in-place height of the vehicle carrying plates on the layer where the in-place detection device is arranged; the emitter and the receiver are arranged on a horizontal straight line parallel to the width direction of the carrier board on the layer to form a correlation light channel; the opposite light channel is vertical to the length direction of the vehicle carrying plate on the layer, the space distance is an effective detection range, and the effective detection range spans the width of the vehicle carrying plate to be detected; the correlation type photoelectric switch is in signal connection with a parking equipment control system; when no barrier exists in the opposite light channel, the opposite light type photoelectric switch outputs a conducting signal to a parking equipment control system to allow the ascending or descending operation control of the layer of vehicle carrying board; when the opposite light transmission middle channel has an obstacle, the opposite light type photoelectric switch outputs a shielding signal to the parking equipment control system, the shielding signal indicates that the vehicle carrying plate is lifted in place, and the parking equipment control system is triggered to carry out control related to the lifting in place of the vehicle carrying plate on the layer.
The over-limit detection device is used for detecting the rising over-limit of the vehicle carrying plate, is a correlation type photoelectric switch, is provided with a set of each layer except the vehicle entering and exiting layer, is arranged at the rear position of the equipment rack and is positioned above the in-place detection device of the layer, and comprises a transmitter and a matched receiver; the emitter and the receiver are arranged on a horizontal straight line parallel to the width direction of the carrier board on the layer to form a correlation light channel; the opposite light channel is vertical to the length direction of the vehicle carrying plate on the layer, the space distance is an effective detection range, and the effective detection range spans the vehicle carrying plate to be detected; the correlation type photoelectric switch is in signal connection with a parking equipment control system and a lifting motor driving circuit in a strong electric control system; when no barrier exists in the middle of the opposite light channel, the opposite light type photoelectric switch outputs a conducting signal to the parking equipment control system, and the situation that the lifting of the layer of vehicle carrying plate is over-limit does not exist; when an obstacle exists in the middle of the correlation light channel, the correlation photoelectric switch outputs a shielding signal to a strong current control system, the shielding signal indicates that the lifting of the vehicle carrying plate exceeds the limit, and the strong current control system is directly triggered to stop supplying power to the vehicle carrying plate lifting driving motor, so that the lifting driving motor stops running, and the vehicle carrying plate stops lifting; the 'shielding' signal is simultaneously output to a parking equipment control system to trigger the parking equipment control system to carry out control related to the ascending overrun of the layer of the vehicle carrying board.
The light barrier is matched with the vehicle carrying plates, one vehicle carrying plate is arranged, and the installation position of the light barrier is matched with the in-place detection device and the over-limit detection device which are arranged on the layer where the vehicle carrying plate is located; when the vehicle carrying plate rises to a position over the layer in-place height, the light barrier can shield an optical channel of the correlation type photoelectric switch of the in-place detection device, so that the correlation type photoelectric switch outputs a shielding signal outwards; when the vehicle carrying plate rises to a position of exceeding the limit height of the layer, the light barrier can shield the optical channel of the correlation type photoelectric switch of the overrun detection device, so that the correlation type photoelectric switch outputs a shielding signal to the outside.
Further, the above basic technical solution is changed, and is characterized in that: the installation positions of the in-place detection device, the overrun detection device and the light barrier are changed, and the method specifically comprises the following steps: the in-place detection device is arranged in the front position of the equipment rack; the overrun detection device is arranged in the front of the equipment rack and is positioned above the in-place detection device on the layer; the installation position of the light barrier is matched with the positions of the in-place detection device and the over-limit detection device which are installed on the layer where the car carrying plate is located.
The installation positions of the in-place detection device and the overrun detection device are selected to be behind or in front of the equipment rack, so that factors influencing detection can be avoided to the maximum extent.
Further, the aforementioned basic technical solution is changed, and is characterized in that: the installation number of the in-place detection devices is changed, and specifically: the in-place detection device is used for detecting that the vehicle carrying plate rises in place and is a correlation type photoelectric switch, more than one correlation type photoelectric switch is arranged on each layer except the vehicle entering and exiting layer, the correlation type photoelectric switches are identical in structure and performance, the installation heights are on the same horizontal line, output signals of the correlation type photoelectric switches are respectively output outwards and are in signal connection with a parking equipment control system, and the control system performs control judgment according to received detection signals.
The preferable method for the parking equipment control system to make detection judgment according to the output signal of the correlation photoelectric switch is as follows:
if the correlation photoelectric switches externally output logic "1" when no obstacle exists in the correlation optical channel and externally output logic "0" when an obstacle exists, the correlation detection and judgment is as follows:
in the first case, the outgoing signals of the correlation photoelectric switches are all "1", that is, it is determined that there is no obstacle.
In the second case, the outgoing signals of the opposed photoelectric switches are all "0", that is, it is determined that there is an obstacle.
In the third case, the external output signals of the corresponding photoelectric switches are all "0", and then, the external output signal of one of the corresponding photoelectric switches jumps to "1", that is, it is determined that there is no obstacle and there is an obstacle, and some of the corresponding photoelectric switches have a fault, and it is necessary to prompt for treatment.
In the fourth case, the external output signals of the corresponding photoelectric switches are all "1", and then, the external output signal of one of the corresponding photoelectric switches jumps to "0", that is, it is determined that there is no obstacle and the corresponding photoelectric switch has a fault, and a prompt is required to be provided.
If the correlation photoelectric switches externally output logic "0" when no obstacle exists in the correlation optical channel and externally output logic "1" when an obstacle exists, the correlation detection and judgment is as follows:
in the first case, the outgoing signals of the correlation photoelectric switches are all "0", that is, it is determined that there is no obstacle.
In the second case, the outgoing signals of the opposed photoelectric switches are all "1", that is, it is determined that there is an obstacle.
In the third case, the external output signals of the corresponding photoelectric switches are all "1", and then, the external output signal of one of the corresponding photoelectric switches jumps to "0", that is, it is determined that there is no obstacle and there is an obstacle, and a fault exists in some of the corresponding photoelectric switches, and it is necessary to prompt for treatment.
In the fourth case, the external output signals of the corresponding photoelectric switches are all "0", and then, the external output signal of one of the corresponding photoelectric switches jumps to "1", that is, it is determined that there is no obstacle and the corresponding photoelectric switch has a fault, and it is necessary to prompt for treatment.
The number of in-place detection devices is increased, and the purpose is to improve the reliability of in-place detection. When one of the in-place detection devices fails, the detection effect is not influenced. Moreover, related faults can be timely discovered and prompted to be disposed.
Further, the aforementioned basic technical solution is changed, and is characterized in that: the number of the installation of the overrun detecting devices is changed, and specifically comprises the following steps: the over-limit detection device is used for detecting that the vehicle carrying plate rises to the right position, is a correlation type photoelectric switch, more than one set of correlation type photoelectric switches are arranged on each layer except the vehicle entering and exiting layer, the correlation type photoelectric switches have the same structure and performance, the installation heights are on the same horizontal line, and the correlation type photoelectric switches are arranged on the layer in-place detection device; output signals of the correlation type photoelectric switches are respectively output outwards and are in signal connection with a parking equipment control system, and the control system performs control judgment according to received detection signals; then, the output signals of the correlation photoelectric switches are subjected to logical operation processing and then are in signal connection with a lifting motor driving circuit in a strong electric control system, and when any correlation photoelectric switch generates a vehicle carrying board lifting overrun detection signal, the driving power supply of the lifting motor is directly interrupted.
The parking equipment control system and the strong electric control system receive the output signal of the correlation photoelectric switch to make the related detection judgment and control, and the preferable method is as follows:
if the correlation photoelectric switches externally output logic '1' when no barrier exists in the correlation light channel and externally output logic '0' when a barrier exists in the correlation light channel, output signals of the correlation photoelectric switches are respectively externally output and are in signal connection with a parking equipment control system; then, the output signals of the correlation photoelectric switches are accessed to a lifting motor driving circuit in a strong electric control system after logical AND operation, and the related detection, judgment and control are as follows:
in the first case, the external output signals of the correlation photoelectric switches are all '1', and the parking equipment control system judges that no obstacle exists; the output signals of the correlation photoelectric switches are subjected to logic AND operation, the output signals are 1, and a running permission signal is output to the lifting motor driving circuit.
In the second case, the external output signals of the correlation photoelectric switches are all '0', and the parking equipment control system judges that an obstacle exists; the output signals of the correlation photoelectric switches are subjected to logic AND operation, the output signals are 0, and an 'operation interruption' signal is output to the lifting motor driving circuit.
In the third situation, the external output signals of the correlation photoelectric switches are different, and the parking equipment control system judges that a part of the correlation photoelectric switches have faults and needs to prompt for treatment; the output signals of the correlation photoelectric switches are subjected to logic AND operation, the output signals are 0, and an 'operation interruption' signal is output to the lifting motor driving circuit.
If the correlation photoelectric switches externally output logic '0' when no barrier exists in the correlation light channel and externally output logic '1' when the barrier exists, the output signals of the correlation photoelectric switches are respectively externally output and are in signal connection with a parking equipment control system; then, the output signals of the correlation photoelectric switches are inverted, logically 'AND' operated and then connected to a lifting motor driving circuit in a strong electric control system, and relevant detection, judgment and control are as follows:
in the first case, the external output signals of the correlation photoelectric switches are all '0', and the parking equipment control system judges that no obstacle exists; the output signals of the correlation photoelectric switches are inverted, and the external output signal after logical AND operation is 1, and a running permission signal is output to the lifting motor driving circuit.
In the second case, the external output signals of the correlation photoelectric switches are all '0', and the parking equipment control system judges that an obstacle exists; the output signals of the correlation photoelectric switches are inverted, and the external output signals after logical AND operation are 0, and output an 'interrupted operation' signal to the lifting motor driving circuit.
In the third situation, the external output signals of the correlation photoelectric switches are different, and the parking equipment control system judges that a part of the correlation photoelectric switches have faults and needs to prompt for treatment; the output signals of the correlation photoelectric switches are inverted, and the external output signals after logical AND operation are 0, and then the signals of 'interrupted operation' are output to the lifting motor driving circuit.
The number of overrun detection devices is increased, and the purpose is to improve the reliability of overrun detection. When one of the multiple overrun detection devices fails, the detection effect is not influenced. Moreover, related faults can be timely discovered and prompted to be disposed.
Further, the aforementioned basic technical solution is changed, and is characterized in that: the light barrier is cancelled, and the function is replaced by the steel structure parts of the car carrying plate.
The purpose of arranging the light barrier is to shield the opposite light channel of the detection device during the operation of the vehicle carrying board. Therefore, the simplest method is to replace the steel structural parts of the vehicle carrying plate. Of course, the provision of the light blocking plate has an advantage in that adjustment of the blocking position is easy.
Further, the control method of the ascending detection device of the vehicle carrying board is characterized in that: when the vehicle carrying plates of all layers of the parking equipment are located at normal standing positions, the in-place detection device and the overrun detection device which are installed on all layers do not detect obstacles.
When one of the vehicle carrying plates on a certain layer runs from the normal standing position of the layer to the lower part, the in-place detection device and the overrun detection device which are arranged on each layer do not detect the obstacle.
When one of the vehicle carrying plates in a certain layer moves upwards from a position below the layer until a light barrier arranged on the vehicle carrying plate starts to shield a correlation light channel of a correlation photoelectric switch of the in-place detection device arranged on the layer, the correlation photoelectric switch outputs a shielding signal to a parking equipment control system, the signal triggers the parking equipment control system to send a signal for stopping the ascending operation to a vehicle carrying plate ascending and descending driving system, and the vehicle carrying plate does not ascend any more; then, the parking equipment control system sends a signal of slow descending operation to the vehicle carrying board lifting driving system, the vehicle carrying board slowly descends until the opposite light channel of the opposite photoelectric switch of the in-place detection device installed on the layer by the light barrier installed on the vehicle carrying board is changed from a shielding state to a non-shielding state, so that the opposite photoelectric switch outputs a 'conducting' signal to the parking equipment control system, the signal triggers the parking equipment control system to send a signal of stopping descending operation to the vehicle carrying board lifting driving system, and the vehicle carrying board does not descend any more and is in a state of standing on the layer.
When one of the vehicle carrying plates of a certain layer runs upwards from a position below the layer until a light barrier arranged on the vehicle carrying plate starts to shield a correlation light channel of a correlation photoelectric switch of an in-place detection device arranged on the layer, if the vehicle carrying plate continues to rise due to an abnormal condition, when the vehicle carrying plate rises to exceed the height of the in-place position and reaches the height of a limit position, the light barrier arranged on the vehicle carrying plate starts to shield the correlation light channel of the correlation photoelectric switch of the over-limit detection device arranged on the layer, and the signal directly triggers a strong electric control system to stop supplying power to a vehicle carrying plate lifting driving motor, so that the vehicle carrying plate does not rise any more; and simultaneously, triggering a parking equipment control system to send out a fault alarm signal.
The abnormal condition includes one or more of the following:
first, the in-place detection device fails to output a "mask" signal to the parking equipment control system.
Secondly, the signal connecting line between the in-place detection device and the parking equipment control system is in fault, and the 'shielding' signal output by the in-place detection device cannot be received by the parking equipment control system.
Thirdly, the parking equipment control system fails, and the 'shielding' signal output by the in-place detection device cannot be normally handled by the parking equipment control system.
Fourth, the command output line of the parking equipment control system fails, and the command to stop the ascending operation issued by the parking equipment control system is not received by the strong electric control system.
And fifthly, the control function of the strong electric control system is failed, and the related control instructions cannot enable the vehicle carrying board lifting driving system to stop lifting operation.
From the above description, it can be seen that: the control logic of the basic technical scheme of the vehicle carrying board rising detection device is very simple.
After the basic technical solution is changed, the related control logic is basically the same as that of the basic technical solution, and is not described herein again.
The invention has the advantages that: keeping lifting and horizontal moving parking equipment simple structure, the cost of manufacture is low, maintain under the convenient prerequisite, need more defects and not enough that detect components and parts and more complicated control logic to current equipment, propose to adopt correlation formula photoelectric switch to detect, every layer only needs to install one set at least and is used for detecting that a sweep targets in place and one set is used for detecting the sweep that carries the sweep transfinites and rises detection device, a complicated system for replacing each sweep installation one set of lifting detection device that targets in place, one set of lifting detection device that transfinites, the cost of manufacture that can further reduce lifting and horizontal moving parking equipment, the stability and the maintainability of improve equipment operation, promote lifting and horizontal moving parking equipment's popularization and application.

As can be seen, this embodiment is a two-level, three-stall, lift-and-traverse parking apparatus; the equipment rack 1 is arranged above the ground floor 7; the parking equipment is provided with two vehicle carrying boards which can only move transversely on a ground layer 7, wherein a first vehicle carrying board 6-1 on the ground layer and a second vehicle carrying board 6-2 on the ground layer are shown from left to right; the parking equipment is provided with three vehicle carrying plates which can only vertically lift on a second layer 8, and the two layers of vehicle carrying plates I5-1, the two layers of vehicle carrying plates II 5-2 and the two layers of vehicle carrying plates III 5-3 are respectively arranged from left to right in the figure; a first light barrier 4-1, a second light barrier 4-2 and a third light barrier 4-3 are respectively arranged above the right sides of the first two-layer vehicle carrying plate 5-1, the second two-layer vehicle carrying plate 5-2 and the third two-layer vehicle carrying plate 5-3; an in-place detection device is arranged on the equipment frame 1 above the position height of the two layers of vehicle carrying plates which normally stand, the in-place detection device consists of an in-place detection emitter 3-1 and an in-place detection receiver 3-2, and a correlation light channel of the in-place detection device crosses the widths of a first two layers of vehicle carrying plates 5-1, a second two layers of vehicle carrying plates 5-2 and a third two layers of vehicle carrying plates 5-3 which need to be detected and is vertical to the length direction of the vehicle carrying plates; an overrun detection device is arranged on the equipment rack 1 above the position height of the in-place detection device, the overrun detection device is composed of an overrun detection emitter 2-1 and an overrun detection receiver 2-2, and a correlation light channel of the overrun detection device crosses the widths of a first two-layer vehicle carrying board 5-1, a second two-layer vehicle carrying board 5-2 and a third two-layer vehicle carrying board 5-3 to be detected and is vertical to the length direction of the vehicle carrying boards; from the foregoing, it can be seen that: the in-place detection device consisting of the in-place detection emitter 3-1 and the in-place detection receiver 3-2 is a photoelectric correlation switch and is in signal connection with a parking equipment control system; the overrun detection device consisting of the overrun detection emitter 2-1 and the overrun detection receiver 2-2 is a photoelectric correlation switch, is in signal connection with a parking equipment control system, and is in signal connection with a lifting motor driving circuit in a strong electric control system.
As can be seen from fig. 1: the first layer of vehicle carrying board 5-1, the second layer of vehicle carrying board 5-2 and the third layer of vehicle carrying board 5-3 are at the height of the second layer 8 at present and are in a normal standing state; at the moment, the first light barrier 4-1, the second light barrier 4-2 and the third light barrier 4-3 are all positioned below the in-place detection device, the in-place detection device does not detect the barrier, a 'conducting' signal is output to the parking equipment control system, and the parking equipment control system judges that the second-layer vehicle carrying plate is in a normal state; the overrun detection device does not detect obstacles, and outputs 'on' signals to the parking equipment control system and the lifting motor drive circuit respectively, the parking equipment control system judges that the two-layer vehicle carrying plate is in a normal state without overrun, and the lifting motor drive circuit is in an allowable running state.
As shown in fig. 2, 3, 4 and 5, the operation of the embodiment shown in fig. 1 is schematically illustrated. Wherein:
as can be seen from fig. 2: and the second layer vehicle carrying board 5-2 descends from the current height position of the second layer 8 to the height position of the ground layer 7 and normally stands. In the descending operation process of the second layer of vehicle carrying board II 5-2, the in-place detection device does not detect the barrier, a 'conducting' signal is output to the parking equipment control system, and the parking equipment control system judges that the second layer of vehicle carrying board is in a normal state; the overrun detection device does not detect obstacles, and outputs 'on' signals to the parking equipment control system and the lifting motor drive circuit respectively, the parking equipment control system judges that the two-layer vehicle carrying plate is in a normal state without overrun, and the lifting motor drive circuit is in an allowable running state.
As can be seen from fig. 3: the second layer vehicle carrying board 5-2 starts to ascend from the current height position of the ground layer 7 and does not reach the height position of the second layer 8. In the ascending operation process of the second-layer vehicle carrying board II 5-2 shown in the figure 3, the in-place detection device does not detect the barrier, a 'conducting' signal is output to the parking equipment control system, and the parking equipment control system judges that the second-layer vehicle carrying board is in a normal state; the overrun detection device does not detect obstacles, and outputs 'on' signals to the parking equipment control system and the lifting motor drive circuit respectively, the parking equipment control system judges that the two-layer vehicle carrying plate is in a normal state without overrun, and the lifting motor drive circuit is in an allowable running state.
As can be seen from fig. 4: when the second layer of vehicle carrying board 5-2 rises to a height position just exceeding the second layer 8, the light barrier 4-2 shields a light emitting channel of the in-place detection device, so that the in-place detection device detects an obstacle, a shielding signal is output to the parking equipment control system to indicate that the vehicle carrying board rises in place, and the parking equipment control system is triggered to send a command of stopping rising operation to the strong electric control system so that the second layer of vehicle carrying board 5-2 stops rising; and then, the parking equipment control system sends a running instruction of slowly descending the second layer of vehicle carrying plate 5-2 to the strong electric control system, so that the second layer of vehicle carrying plate 5-2 starts to slowly descend. In the process, the over-limit detection device does not detect the obstacles, and outputs 'on' signals to the parking equipment control system and the lifting motor driving circuit respectively, the parking equipment control system judges that the two-layer vehicle carrying plate is in a normal state without over-limit, and the lifting motor driving circuit is in an allowed running state.
As can be seen from fig. 5: the second layer of vehicle carrying board 5-2 slowly descends from a height position just passing through the second layer 8, when the second layer of vehicle carrying board 5-2 descends to a height position at which the light blocking board 4-2 no longer shields the opposite light channel of the in-place detection device, the in-place detection device detects that the barrier is away, the opposite light channel is restored to be conducted, namely a 'conducting' signal is output to the parking equipment control system, the parking equipment control system judges that the second layer of vehicle carrying board descends to a normal standing height position, namely a command of stopping descending operation is sent to the strong electric control system, and the second layer of vehicle carrying board 5-2 stops descending; in the process, the over-limit detection device does not detect the obstacles, and outputs 'on' signals to the parking equipment control system and the lifting motor driving circuit respectively, the parking equipment control system judges that the two-layer vehicle carrying plate is in a normal state without over-limit, and the lifting motor driving circuit is in an allowed running state.
Fig. 6 shows that, in the state shown in fig. 4, if an abnormal condition occurs, the second floor vehicle-carrying board 5-2 does not stop but continues to rise when rising to a height position just beyond the second floor 8; when the second layer of vehicle carrying plates 5-2 rises to the light barrier II 4-2 to shield the opposite light channel of the overrun detection device, the overrun detection device detects an obstacle, namely outputs a shielding signal to the parking equipment control system and the lifting motor driving circuit, and the parking equipment control system judges that the second layer of vehicle carrying plates are in an overrun state and immediately starts a fault handling program; and the 'shielding' signal output to the lifting motor driving circuit by the overrun detection device immediately triggers the lifting motor driving circuit to be in a power-off operation prohibition state, and the second layer vehicle carrying plate II 5-2 emergently stops ascending operation, so that the operation safety of the equipment is ensured.
