Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the example embodiments described herein.

[0021] At present, most of the automatic car washing stations are unattended, which may cause many drivers to wash cars without following the specified procedures, quickly pass through the car washing station, and cause the car body to be not washed clean, increase the road pollution, and be not conducive to the ecological civilization construction.

[0022] Therefore, in view of the above problems, the present disclosure provides a control device which can force the vehicle to complete the car washing process according to the specified procedures through radar induction and relay barrier linkage. Compared with the prior art, the present disclosure can effectively avoid the situation that the vehicle leaves without following the specified car washing process, reduce the waste of car washing resources and the disorder of the process, and at the same time, through the excitation self-locking / unlocking mechanism of the relay, the stability of the barrier control is improved, and the risk of misoperation is reduced.

[0023] Firstly, the present disclosure provides a control device, please refer to Figure 1 , Figure 1 The structural block diagram of a control device provided by the embodiment of the present disclosure. As shown in Figure 1 , the device comprises:

[0024] The first radar 101 is arranged at the entrance of the car washing station and is used for sensing the entry of the vehicle;

[0025] The first radar controller 102 is connected to the first radar and is used for starting the relay based on the control of the first radar;

[0026] The relay 103 is used for excitation self-locking or unlocking based on the control of the first radar controller, and controls the lowering or lifting of the barrier;

[0027] The second radar 104 is arranged at the exit of the car washing station and is used for sensing the exit of the vehicle;

[0028] The second radar controller 105 is connected to the second radar and is used for making the barrier enter the anti-smashing state based on the control of the second radar;

[0029] The barrier controller 106 is arranged at the exit of the car washing station and is used for lowering or lifting the barrier based on the control of the relay, and starting the anti-smashing based on the control of the second radar controller;

[0030] Barrier gate 107, for lowering or raising the rod based on the control of the barrier gate controller.

[0031] In the present disclosure, the first radar can be understood as a vehicle detection device at the entrance of the car washing platform, which can monitor whether a vehicle enters the entrance area of the car washing platform in real time. Its main purpose is to capture the vehicle entry signal in time and convert it into an electrical signal to the relay, thereby triggering the subsequent barrier gate lowering and other car washing processes, which can improve the automation of the car washing platform entrance management.

[0032] In the present disclosure, the first radar controller can be understood as a signal processing and control relay unit between the first radar and the relay, with a built-in signal recognition and logic control circuit. Its main purpose is to receive the vehicle entry sensing signal from the first radar, analyze and process the signal, and output corresponding control instructions to the relay to ensure that the relay can accurately perform the excitation self-locking or unlocking action, thereby realizing the initial control trigger of the barrier gate lifting, which is a key control link connecting vehicle detection and execution mechanism.

[0033] In the present disclosure, the relay can be understood as an automatic control switch component working based on electromagnetic principle, which can realize the energization or de-energization of the excitation coil by receiving the electrical signal from the first radar, and then complete the self-locking (keep on state) or unlocking (off state) action of the contact. Its core purpose is to serve as a signal transmission and control execution bridge between the first radar and the barrier gate controller, amplify and convert the sensing signal of the first radar into a control signal that can drive the barrier gate action, and realize the function switching of the barrier gate lifting to release the vehicle or lowering to close the exit.

[0034] In the present disclosure, the second radar can be understood as a vehicle state monitoring device at the exit of the car washing platform, which focuses on detecting whether the vehicle has completely driven away from under the barrier gate. Its main purpose is to accurately judge the vehicle leaving situation, which can avoid the barrier gate from injuring the vehicle or personnel and ensure the safety of the car washing process exit.

[0035] In the present disclosure, the second radar controller can be understood as a signal processing and transmission unit between the second radar and the barrier gate controller, which has signal analysis and logic judgment ability. Its main purpose is to receive the vehicle leaving state signal detected by the second radar, analyze and judge whether the vehicle has completely driven away from the area under the barrier gate, and when it is detected that the vehicle has not completely left or there is an object under the barrier gate, immediately send a anti-smashing trigger signal to the barrier gate controller to make the barrier gate enter the anti-smashing state, which is one of the core control components to ensure the safety of the barrier gate operation.

[0036] In the present disclosure, the barrier controller can be understood as the core control unit of the barrier action, which is built-in with a logic control circuit and a driving module, and is capable of receiving the barrier lifting control signal from the relay and the anti-smashing signal from the second radar. The main purpose is to drive the barrier to perform the lifting rod and lowering rod actions according to the preset logic according to the received different signals, and immediately stop the lowering rod action or control the barrier to reverse the lifting rod when the anti-smashing signal is received, so as to realize the automatic and safe operation of the barrier, and to guarantee the precise control and safety protection of the barrier at the exit of the car washing platform.

[0037] In the present disclosure, the barrier can be understood as the physical interception and release execution mechanism of the entrance and exit of the car washing platform, which is composed of a barrier rod, a driving motor, a mechanical transmission structure and the like. The main purpose is to complete the lifting rod (allowing the vehicle to pass) or lowering rod (prohibiting the vehicle to pass) action by the driving motor driving the barrier rod according to the instruction of the barrier controller, to form the physical control of the entrance and exit of the car washing platform, and to stop the lowering rod or reverse the lifting rod in response to the control in the anti-smashing state, which is the final execution component to realize the orderly entry and exit of the vehicle to the car washing platform.

[0038] In the following, the relay of the present disclosure will be specifically described. The relay of the present disclosure comprises: an intermediate relay and a time relay; the intermediate relay is used for self-locking to maintain the current state, or, releasing the current state; the time relay is used for controlling the lifting rod of the barrier.

[0039] In the present disclosure, the relay is an execution component to realize the control logic of the entrance barrier of the car washing platform. Specifically, the intermediate relay (Intermediate Relay, KA) can be understood as an electromagnetic switch component with amplification and conversion control signal function, which can generate electromagnetic force by energizing the coil to attract the contact to realize self-locking, so as to maintain the stable state required by the barrier control, and can also release the contact by de-energizing the coil to release the self-locking, so as to complete the state switching. The time relay (Time Relay, KT) can be understood as a relay component with time delay control function, which is integrated with a timing module inside, starts timing after receiving a trigger signal, and automatically outputs a control signal to control the lifting rod of the barrier when reaching the preset time delay, so as to realize the time delay opening after the lowering rod of the barrier, and to ensure the safety of the vehicle to exit the car washing platform. The cooperation of the two can complete the automatic control closed loop from the vehicle entering to the lowering rod of the barrier to the time delay lifting rod, and ensure the orderly and controllable barrier action.

[0040] In the following, how the control device of the present disclosure is used will be specifically described, including:

[0041] When the first radar senses the entry of the first vehicle of the car washing platform, a first sensing signal is sent to the first radar controller;

[0042] Based on the first sensing signal, the first radar controller sends a trigger signal to the intermediate relay and the time relay;

[0043] Based on the trigger signal, the intermediate relay charges to maintain the current state and sends a drop rod signal to the gate controller;

[0044] Based on the trigger signal, the time relay records the first time interval;

[0045] Based on the drop rod signal, the gate controller controls the gate to execute the drop rod.

[0046] In the present disclosure, the first induction signal can be understood as an electrical signal generated when the first radar detects that the vehicle enters the entrance area of the car washing platform, which is the initial communication carrier between the first radar and the first radar controller, and its core function is to trigger the first radar controller to start the subsequent control logic.

[0047] In the present disclosure, the trigger signal can be understood as an electrical pulse signal generated after the first radar detects that the vehicle enters, which is an instruction switch for starting the subsequent action of the control device, and can activate the intermediate relay and the time relay at the same time, ensuring that the two relays start working synchronously, and is the starting trigger point of the entire control process.

[0048] In the present disclosure, the drop rod signal can be understood as a specific level signal output by the intermediate relay after self-locking, which, after being transmitted to the gate controller, will trigger the drive module inside the gate controller to control the gate motor to operate, so that the gate rod moves from the raised release state to the fallen closed state, realizing the closure of the entrance of the car washing platform.

[0049] In the present disclosure, the first time interval can be understood as the time length from when the time relay receives the trigger signal to when it sends the lift rod signal to the gate controller. The purpose is to reserve sufficient time for the vehicle to completely enter the inside of the car washing platform, so as to avoid the gate from lifting the rod too early and causing the vehicle to be not washed clean.

[0050] Specifically, when the first radar detects that the front end of the vehicle enters its sensing area, a first induction signal is generated to the first radar controller. The first radar controller sends a trigger signal to the intermediate relay and the time relay; after receiving the trigger signal, the intermediate relay generates electromagnetic attraction through coil power to make the contact point attract and realize self-locking, while transmitting the drop rod signal to the gate controller; after receiving the drop rod signal, the gate controller drives the gate rod to slowly drop until it is horizontal to the ground to complete the closure of the exit; at the same time, the time relay starts timing from the moment when the trigger signal is received, and continuously records the first time interval, preparing for the subsequent gate rod lifting action.

[0051] Exemplarily, Figure 2 The circuit schematic diagram at the entrance of the car washing platform provided by the embodiment of the present disclosure is provided. Figure 3 The circuit schematic diagram at the exit of the car washing platform provided by the embodiment of the present disclosure is provided. As Figure 2 andFigure 3 as shown:

[0052] When the entrance radar senses the first vehicle entering, the contacts 1 and 2 of the entrance radar switch are closed, so that the positive power supply KZ-24v is sequentially supplied to the closed entrance radar switch contacts, the normally open contacts (9-5) of the intermediate relay KA, the coils (A1, A2) of the time relay KT, and the coils (13, 14) of the intermediate relay KA; immediately, the time relay KT starts recording the first time interval, the intermediate relay KA is attracted by the power supply to the coil and realizes self-locking, and sends a drop rod signal to the gate controller through its contacts (such as Figure 3 the related contacts of the intermediate relay KA); after receiving the drop rod signal, the gate controller triggers the internal drive module to control the gate rod to move from the lifted release state to the lowered closed state, closing the entrance of the car washing platform.

[0053] The use control device further comprises:

[0054] When the first time interval meets the preset second time interval, the time relay sends an unlocking signal to the intermediate relay;

[0055] Based on the unlocking signal, the intermediate relay releases the current state and sends a rod lifting signal to the gate controller;

[0056] Based on the rod lifting signal, the gate controller controls the gate to perform rod lifting.

[0057] In the present disclosure, the second time interval can be understood as a preset time threshold for judging whether to start the gate rod lifting process, that is, a standard time length for the vehicle to completely enter the car washing platform and reserve enough time for car washing operation. When the first time interval recorded by the time relay reaches the preset value, the subsequent unlocking and rod lifting actions are triggered.

[0058] In the present disclosure, the unlocking signal can be understood as an electrical signal output by the time relay when the first time interval meets the second time interval. The signal acts on the intermediate relay, causing the coil to lose power and the contacts to reset, thereby releasing the previous self-locking state and preparing for gate rod lifting.

[0059] In the present disclosure, the rod lifting signal can be understood as a specific level signal output by the intermediate relay after the self-locking is released. After being transmitted to the gate controller, it will trigger the internal drive module of the gate controller to reversely drive the gate motor, causing the gate rod to lift from the horizontal closed state to the vertical release state, thereby re-opening the exit of the car washing platform.

[0060] Specifically, when the first time interval recorded by the time relay gradually accumulates and reaches the preset second time interval, the time relay triggers an action and sends an unlocking signal to the intermediate relay; after receiving the unlocking signal, the intermediate relay loses power, causing the electromagnetic attraction to disappear, and the contact to open to release the self-locking state, while transmitting a lifting rod signal to the gate controller; the gate controller responds to the lifting rod signal and drives the gate rod to slowly rise from the closed state until it returns to the release position.

[0061] Exemplarily, from Figure 2 and Figure 3 As can be seen: when the first time interval recorded by the time relay KT reaches the preset second time interval, the normally closed contact (such as 15-16) of KT is disconnected, the normally open contact (such as 13-14) is closed, and an unlocking signal is sent to the intermediate relay KA; the intermediate relay KA loses power, its self-locking contact (9-5) is disconnected to release the self-locking, and the state of the output contact (such as Figure 3 the related contact of KA) connected with the gate controller is reversed, and a lifting rod signal is sent to the gate controller; after receiving the lifting rod signal, the gate controller controls the gate motor to reverse, and the gate rod gradually rises from the horizontal closed state until it returns to the vertical release state, completing a control cycle from closing to opening of the entrance gate.

[0062] The use control device further comprises:

[0063] When the second radar senses that the first vehicle on the car washing platform leaves, a second sensing signal is sent to the second radar sensor;

[0064] Based on the second sensing signal and the first sensing signal, the second radar sensor sends a smashing prevention signal to the gate controller;

[0065] Based on the smashing prevention signal, the gate controller controls the gate to maintain the lifting rod until receiving a reset signal from the second radar controller; the reset signal is used to indicate that the first vehicle has driven away from the exit of the car washing platform.

[0066] In the present disclosure, the second sensing signal can be understood as an electrical signal generated when the second radar detects that the first vehicle starts to drive away from the exit area of the car washing platform, which carries the state information that the vehicle is leaving the exit, and is a communication carrier between the second radar and the second radar controller. Its core role is to deliver the initial state of the vehicle leaving the exit to the second radar controller, to provide the original basis for the second radar controller to judge whether to start the smashing prevention protection in combination with the first sensing signal (indicating that a new vehicle enters the entrance), and is a key initial signal to trigger the exit safety control process.

[0067] In the present disclosure, the anti-bashing signal can be understood as a safety protection signal output by the second radar when it detects that the first vehicle has left the exit area and the first radar simultaneously detects that the second vehicle has entered the entrance area. After the signal is transmitted to the barrier controller, the barrier is forced to maintain the lifting state, avoiding the barrier from being unexpectedly lowered during the alternating passage of the front and rear vehicles, and thus preventing the bashing accident. It is a key signal to ensure the safety of vehicle passage.

[0068] In the present disclosure, the reset signal can be understood as a state recovery signal output by the second radar when the first vehicle has completely driven away from the exit area of the car washing platform. The signal is used to inform the barrier controller that the first vehicle has safely left and there is no need to maintain the anti-bashing protection state, so as to make the barrier controller return to the normal control logic and respond to the subsequent lowering or lifting instructions.

[0069] Specifically, when the second radar senses that the tail of the first vehicle is still in its sensing area (i.e., the vehicle has not completely driven away from the exit of the car washing platform), it continuously sends a second sensing signal to the second radar controller. At the same time, the second radar controller receives the continuous signal, and if it detects that the first radar has sent a first sensing signal (indicating that the second vehicle has entered the entrance area), it determines that it is in a critical state of alternating passage of the front and rear vehicles, and continuously outputs an anti-bashing signal to the barrier controller. Based on the anti-bashing signal, the barrier controller locks the lifting state of the barrier, so that even if the time relay or the intermediate relay issues a lowering instruction at this time, the lowering action will not be performed. Until the second radar senses that the tail of the first vehicle has completely driven away from its sensing area (i.e., the vehicle has completely left the exit area), it stops sending the second sensing signal and instead sends state information that the vehicle has completely left to the second radar controller. The second radar controller generates a reset signal based on this and transmits it to the barrier controller, and the barrier controller only releases the anti-bashing lock and restores the response ability to other control signals.

[0070] Exemplarily, from Figure 2 and Figure 3 It can be seen that: when the first radar senses the entry of the second vehicle, the entrance radar switch contact is closed again (1 and 2 are connected); at the same time, the second radar senses that the first vehicle has left the exit area, and the exit radar switch contact is switched from the closed state to the open state (or a specific contact action, such as Figure 3When the first vehicle is completely driven out of the exit, the second radar cannot detect the vehicle, and the exit radar switch contact returns to the initial closed (or reset state) and sends a reset signal to the gate controller; after the gate controller receives the reset signal, the anti-smashing state is released, and the normal control logic is restored, and the gate can be controlled to rise and fall according to the subsequent entrance radar or relay signal, thereby ensuring the safety and orderliness of vehicle alternation passing through the car washing platform.

[0071] Hereinafter, the specific structure of each unit in the control device of the present disclosure will be specifically described, including:

[0072] The first radar and / or the second radar include at least one of the following: a microwave radar, an infrared radar, and an ultrasonic radar.

[0073] Specifically, the microwave radar is mainly composed of a transmitting antenna, a receiving antenna, and a signal processing module. By transmitting and receiving high-frequency electromagnetic waves, the distance and speed of the target are obtained after processing the echo signal, which has the advantages of long detection distance and strong anti-interference, and is suitable for long-distance detection. The infrared radar is composed of an infrared detector and an optical system, etc. By collecting the infrared energy of the target and converting it into an electric signal for processing, it is sensitive to hot targets, but the detection distance is short and affected by weather, and is mainly used for short-distance hot target detection. The ultrasonic radar includes a transmitter, a receiver and a control unit, transmits ultrasonic waves and receives reflected waves, and calculates the distance to the obstacle. It has the advantages of simple structure, low cost and high precision, and is suitable for short-distance obstacle avoidance scenes.

[0074] The intermediate relay includes at least one of the following: an electromagnetic intermediate relay and a hybrid intermediate relay; the time relay includes at least one of the following: an air damping time relay, an electronic time relay, and an electromagnetic time relay.

[0075] Specifically, the electromagnetic intermediate relay is composed of an electromagnetic system, a contact system and a spring, etc. The contact action is controlled by the on-off of the coil.

The hybrid intermediate relay combines electromagnetic mechanism and electronic control circuit, and has the reliability of electromagnetic relay and the control flexibility of electronic relay, and is suitable for occasions with high control function requirements.

[0076] The air damping type time relay is composed of an electromagnetic system, a time delay mechanism and a contact system, and can realize time delay by air bag exhaust, has wide time delay range and simple structure, and is used in scenes with low time delay precision requirement. The electronic type time relay adjusts time delay through a timing circuit, has high time delay precision, wide range and convenient adjustment, and is widely used in high-precision automatic control circuits. The electromagnetic type time relay realizes time delay by relying on magnetic flux change of an electromagnetic coil, has simple and reliable structure, but has narrow time delay range and low precision.

[0077] The barrier controller comprises at least one of: a microcontroller, a programmable logic controller.

[0078] Specifically, the microcontroller takes a microprocessor as a core, integrates multiple functional modules, receives external signals and controls execution elements according to a program, realizes barrier action, has small size and low cost, and is suitable for small-sized intelligent barrier control. The programmable logic controller is composed of a central processing unit, a memory and the like, has high reliability, strong anti-interference and good expansibility, can adapt to complex industrial environments, and is suitable for large-sized barrier control systems or multi-device linkage scenes.

[0079] The present disclosure further provides a control method, comprising:

[0080] When the first radar senses vehicle entry, relay control is started; the relay is magnetized and self-locked or unlocked based on the control of the first radar;

[0081] Based on the control of the relay, the barrier controller is used to lower or raise the barrier; based on the control of the second radar, the barrier controller starts anti-smashing; the second radar senses vehicle departure and controls the barrier to enter the anti-smashing state.

[0082] Specifically, when the first radar senses vehicle entry, a trigger signal is immediately sent to the intermediate relay and the time relay; the intermediate relay is magnetized and self-locked after receiving the signal, sends a lowering signal to the barrier controller, and the barrier controller drives the barrier to lower; at the same time, the time relay starts recording a time interval, and when the interval reaches a preset value, the time relay sends an unlocking signal to the intermediate relay, the intermediate relay is unlocked and sends a raising signal, and the barrier controller drives the barrier to raise. If the first radar senses the entry of the next vehicle and the second radar senses the departure of the previous vehicle, the second radar sends an anti-smashing signal to the barrier controller, so that the barrier controller maintains the barrier raising state; when the previous vehicle completely drives away from the exit, the second radar sends a reset signal, and the barrier controller restores the normal control logic and waits for subsequent raising and lowering instructions.

[0083] The present disclosure further provides a computer program product comprising a computer program, which, when executed by a processor, implements the control method of any one of the preceding embodiments of the present disclosure.

[0084] In summary, the present disclosure provides a car washing platform control device, method and program product. The present disclosure sets a first radar at the entrance of the car washing platform to sense the entry of a vehicle and control the starting of a relay; the relay is used to magnetize self-locking or unlock based on the control of the first radar, and control the lowering or raising of the barrier pole; a second radar is set at the exit of the car washing platform to sense the exit of the vehicle and control the barrier to enter the anti-smashing state; a barrier controller is set at the exit of the car washing platform to control the lowering or raising of the barrier based on the control of the relay, and to start the anti-smashing based on the control of the second radar. In this way, the present disclosure uses radar sensing and relay barrier linkage to force the vehicle to complete the car washing process according to the specified procedure. Compared with the prior art, the present disclosure can effectively avoid the situation that the vehicle does not complete the car washing process according to the specified procedure and leaves arbitrarily, reduce the waste of car washing resources and the problem of process confusion, and at the same time, through the magnetizing self-locking / unlocking mechanism of the relay, the stability of the barrier control is improved, and the risk of misoperation is reduced.
