detailed description

Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

Referring to Fig. 1, the present invention provides a garage full-environment cruise detection system, which is applied to a garage. The garage has several berths for placing vehicles, and each berth directly above and/or directly below corresponds to at least one The berth frame; the berth frame is the vehicle-carrying plate, which is used to carry the vehicle, and one berth frame is equivalent to one parking space. For example, a three-story garage has three parking spaces on each floor. Suppose the parking spaces on the top floor are A1, A2, and A3 from left to right, and the parking spaces on the middle floor are B1, B2, and B3 from left to right. The parking spaces on the lowest floor are C1, C2, and C3 from left to right. For A2, there is no berth frame directly above it, and there are two berth frames B2 and C2 directly below it. is A1, and directly below is C1.

The garage full-environment cruising detection system of the present invention includes a power supply, a PLC controller, a lifting mechanism, a lateral movement mechanism, a limit switch detection module, an infrared beam detector, a microwave detector, a leakage detection module, an undervoltage detection module, The phase error detection module and the short circuit detection module; the structures of the lifting mechanism and the traverse mechanism are known from the prior art, and generally include guide rails, motors, relays and the like. The power supply is composed of PLC controller, lifting mechanism and traversing mechanism; the lifting mechanism is used to drive the berth frame to move in the height direction, and the traversing mechanism is used to drive the berth frame to move in the length direction; among them, the lifting mechanism and the traversing mechanism , limit switch detection module, infrared radiation detector, microwave detector, leakage detection module, under-overvoltage detection module, phase error detection module and short-circuit detection module are all connected to the PLC controller; The voltage detection module, the wrong-phase detection module and the short-circuit detection module are all connected to the lifting mechanism, and the leakage detection module, the under-overvoltage detection module, the wrong-phase detection module and the short-circuit detection module are all connected to the traverse mechanism.

For example, according to the example of the previous three-story garage (in the following description, empty means that there is no vehicle parked in the parking space, and full means that there are vehicles parked in the parking space), the uppermost layer A2 is empty, A1 and A3 are full, and the middle layer B1 And B2 is full, and B3 is empty. At this time, the vehicle at position C2 needs to be parked at position A2, then the PLC controller controls the traversing mechanism to move the vehicle at position B2 to position B3, and then the PLC controller controls the lifting mechanism to move the vehicle at position C2 to position A2. The vehicle moves to the position of A2.

Leakage detection module, under-overvoltage detection module, phase-wrong detection module and short-circuit detection module are all static detection of the garage, that is, detection is performed before the lifting mechanism and traverse mechanism start. When leakage, undervoltage, overvoltage are detected , wrong phase, or short circuit, the lifting mechanism and traversing mechanism will not be activated. The leakage detection module can be a leakage circuit breaker, which will automatically disconnect the connection between the lifting mechanism, traversing mechanism and the power supply , the short-circuit detection module can be a combination of thermal relay and leakage circuit breaker. When a short-circuit occurs, the connection between the lifting mechanism, the traverse mechanism and the power supply will be automatically disconnected. The phase-wrong detection module can be a phase sequence protector. The above-mentioned faults will Cause damage to other components, there is a serious safety hazard.

The limit switch detection module is also the travel switch, which can realize sequence control and position state detection. It is used to send the in-position signal to the PLC controller when it detects that the parking rack is in place. The infrared beam detector is used to send a blocking signal to the PLC controller, the microwave detector is used to detect the human body signal in the garage, and sends the human body signal to the PLC controller, and the PLC controller is used to control the lifting mechanism according to the in-position signal and/or the blocking signal and/or the human body signal and/or the traversing mechanism stops. The working principle of the infrared through-beam detector is a known technology, including an infrared emitting tube and an infrared receiving tube. The infrared emitting tube and the infrared receiving tube are respectively installed at preset positions. Under normal circumstances, the infrared light emitted by the infrared emitting tube is received The tube receives normally, but when there is an obstacle, the infrared receiving tube cannot receive infrared light normally, as shown in Figure 3. If the parking position of the vehicle does not meet the specifications, or the door is opened, the vehicle may be scratched. At this time, the infrared radiation detector can detect that there is a vehicle blocking the infrared light. The PLC controller controls the lifting mechanism and the lateral movement mechanism to stop. To prevent accidents, the dotted line in Figure 3 represents infrared light, the boxes corresponding to A1, A2... each parking rack represent vehicles, and the parking position of the vehicle at B2 exceeds the preset position and shifts to B1, thus blocking the infrared light Light. When the infrared detector scans the people or pets inside the garage, the PLC controller controls the lifting mechanism and the traverse mechanism to stop running to avoid causing harm to people and pets.

In addition, the present invention also includes a timer connected to the PLC controller, the timer is used to detect the travel time of the lifting mechanism or the traverse mechanism, and sends the travel time signal to the PLC controller, so that the PLC controller can act as the travel time signal When the preset duration is reached, the lifting mechanism or the traverse mechanism is controlled to stop. The timer is combined with the limit switch detection module and the infrared beam detector to further detect whether the parking rack is accurately parked at the target position.

It also includes an overheight detection module connected with the PLC controller, and the overheight detection module is used for sending an overheight signal to the PLC controller when detecting a vehicle on the berth, so that the PLC controller controls the lifting mechanism to stop. In fact, the ultra-high detection module can also use infrared sensors. Some vehicles are higher than the height of each floor of the garage. If you do not know the situation, park the vehicle on the middle floor or the uppermost floor. It will rub against the parking rack or the roof of the garage on the upper floor and cause damage. Refer to Figure 4 for the setting of the exceeding detection module. The dotted line in Figure 4 represents infrared light. When the height of the vehicle is too high, it will block the infrared light. The vehicle corresponding to the position B2 in Figure 4 is seriously higher than the floor height. The mechanism is controlled, and the B2 parking rack continues to rise, which will inevitably cause damage to the vehicles on the B2 parking rack. Through the ultra-high detection module, the vehicles on the B2 parking rack block the infrared light, so that the PLC controller can control the lifting mechanism to stop.

The present invention also includes an emergency stop switch, which is connected to the PLC controller; and an overload detector connected to the PLC controller, which is used to control the lifting mechanism and /or the traverse mechanism is disconnected from the power supply, and sends an overload detection signal to the PLC controller. Overload detector The thermal relay will be detected by the overload detector after heating, and then the power supply will be cut off directly, and the feedback signal will be sent to the PLC controller. The working principle is that the heat deforms the bimetal sheets with different expansion coefficients. When the deformation reaches a certain distance , to push the connecting rod to disconnect the circuit and realize overload protection.

The present invention also provides a garage full-environment cruising detection method, which is applied to the garage full-environment cruising detection system of the present invention, referring to FIG. 2 , including the following steps:

Step S1: The leakage detection module detects the leakage information of the lifting mechanism and the traversing mechanism, and sends the leakage detection signal to the PLC controller; the undervoltage detection module detects the undervoltage information of the lifting mechanism and the traversing mechanism, and sends the undervoltage detection The signal is sent to the PLC controller; the phase error detection module detects the phase error information of the lifting mechanism and the lateral movement mechanism, and sends the phase error detection signal to the PLC controller; the short circuit detection module is used to detect the short circuit information of the lifting mechanism and the lateral movement mechanism, and Send the short circuit detection signal to the PLC controller; before starting the lifting mechanism and the traversing mechanism, perform static detection to ensure the safe operation of the garage.

Step S2: The PLC controller judges whether the lifting mechanism and/or the traversing mechanism is leaking according to the leakage detection signal, and if so, disconnects the connection between the traversing mechanism, the lifting mechanism and the power supply, otherwise, executes step S3;

Step S3: According to the undervoltage detection signal, it is judged whether the lifting mechanism and/or the traversing mechanism is under overvoltage, if so, disconnect the connection between the traversing mechanism, the lifting mechanism and the power supply, otherwise, execute step S4;

Step S4: According to the out-of-phase detection signal, it is judged whether the lifting mechanism and/or the traversing mechanism are out of phase, and if so, disconnect the connection between the traversing mechanism, the lifting mechanism and the power supply, otherwise, execute step S5;

Step S5: Determine whether the lifting mechanism and/or the traversing mechanism are short-circuited according to the short-circuit detection signal, and if so, disconnect the connection between the traversing mechanism, the lifting mechanism and the power supply, otherwise, perform step S6: start the lifting mechanism and the traversing mechanism.

The order of steps S2 to S5 can be adjusted, not necessarily according to the order of this embodiment. These four steps are all judgments. When the four steps are taken as a whole, it is equivalent to a logical or judgment. If they are all judged as No, Then start the lifting mechanism and the traversing mechanism to make the parking frame move in the height direction or the length direction, and perform step S7, otherwise, disconnect the traversing mechanism, the lifting mechanism and the power supply; that is, when any of the above detections When the device detects a fault, it disconnects the connection between the traversing mechanism and the lifting mechanism and the power supply.

Step S7: The infrared beam detector detects the blocking information of the obstacle, and sends the blocking signal to the PLC controller; the microwave detector detects the human body signal in the garage, and sends the human body signal to the PLC controller; the limit switch detection module detects Send a signal to the PLC controller when the parking rack is in place.

Step S8: The PLC controller controls the lifting mechanism and/or the traverse mechanism to stop according to the in-position signal and/or the blocking signal and/or the human body signal.

For example, when the parking rack at position C3 is going to move to position C2, the traversing mechanism controls the parking rack during the movement process. Due to equipment failure or other reasons, the parking rack does not stop at the standard position, but continues to move to position C1. If this If it is not stopped, the vehicle at position C1 will collide or scratch with the moving vehicle. When the infrared detector detects that the moving vehicle exceeds the standard position, it will send a blocking signal to the PLC controller. To control the traverse mechanism to stop in time.

According to the record of the whole-environment cruise detection system of the garage, it can also include a counter, an ultra-high detection module and an overload detector, and then step Sa is also included between step S7 and step S8: the timer detects the travel time of the lifting mechanism or the traverse mechanism, And send the travel time signal to the PLC controller; in step S8, the PLC controller also controls the lifting mechanism and the traverse mechanism to stop when the travel time signal reaches a preset duration. Step Sb is also included between step Sa and step S8: when the overheight detection module detects a vehicle on the berth rack, it sends an overheight signal to the PLC controller; in step S8, the PLC controller also controls the lifting mechanism to stop according to the overshoot signal. It also includes step S9: when the overload detector detects the heating of the lifting mechanism and the traverse mechanism, it controls the lift mechanism and/or the traverse mechanism to be disconnected from the power supply, and sends an overload detection signal to the PLC controller.
