Description

Technical Field

[0001] The utility model relates to the technical field of highway equipment manufacturing, in particular to a control device for a barrier. Background Art

[0002] With the advancement of automobile industry technology and the rapid development of the economy, the total number of cars in operation in society has increased rapidly, and the increase in highway mileage has significantly facilitated residents' travel. Therefore, the management scenarios faced by highway toll stations are gradually increasing, which puts higher requirements on the barrier control device.

[0003] Existing highway toll stations have basically implemented an unmanned management mode, such as the automatic lifting and lowering system of the ETC lane, which usually automatically controls the barrier to open after the ETC device reads the vehicle license plate information, and releases the vehicle that is about to drive onto the highway. However, the blocking and lowering action is usually automatically controlled by another set of control devices. In the prior art, this lowering control device is usually implemented by an induction coil buried in the ground below the vehicle toll stop position in conjunction with a related circuit device. When a vehicle enters the toll stop position, the induction coil receives an induction signal and controls the barrier to remain in a raised state. When the vehicle leaves the above-mentioned toll stop position, the induction coil controls the barrier to be lowered to prepare for the entry of the next vehicle. For example, a Chinese patent document with publication number CN 202492817 U discloses a double-arm split-type ultra-high-speed barrier machine, which has a lowering ground sensing coil located between the left-hand barrier machine and the right-hand barrier machine and on the ground below the barrier arm, and the lowering ground sensing coil is connected to a synchronous controller to control the barrier to drop.

[0004] However, in reality, the effective sensing distance of the induction coil located on the ground for vehicles above the ground is limited. When some vehicles with higher chassis or vehicles loaded with cargo that exceeds the length of the vehicle body pass by, the sensing stability of the induction coil will be reduced. That is, the induction coil may lose its sensing signal to the above-mentioned vehicle before it completely leaves the sensing range of the induction coil, and it may think that the vehicle has left the toll stop, thereby controlling the barrier to fall immediately, causing the bar to hit the vehicle or cargo, which may easily affect driving safety and cause property damage. Utility Model Content

[0005] In order to solve the above problems, the utility model proposes a control device suitable for barrier barriers at high-speed toll stations, which can automatically detect various types of vehicles and safely perform the barrier-dropping action to ensure the safety of passing vehicles and property.

[0006] In order to achieve the above technical objectives, the specific technical solutions adopted by the utility model are as follows:

[0007] A control device suitable for a barrier at a highway toll station, comprising a power supply and an induction coil circuit, and characterized in that it also comprises a detection radar and a control relay connected to the power supply; the control relay comprises a first relay, the detection radar is connected to the coil of the first relay, and is used to control the normally closed contact of the first relay; the induction coil circuit is connected in series with the normally closed contact of the first relay, and when the detection radar detects a vehicle, the normally closed contact of the first relay is disconnected, and the induction coil circuit is disconnected.

[0008] Therefore, the power supply serves as the power supply end of the entire control device, and is used to power the detection radar. The induction coil circuit is a circuit in the prior art, and has a normally closed contact inside. When the induction coil detects a vehicle within the toll stop range, the normally closed contact is disconnected, and the barrier is not energized, that is, the barrier does not drop. When the induction coil loses the detection target, the normally closed contact is closed again, the barrier is energized, and the barrier drops.

[0009] The detection radar is an induction radar, which can be installed on a support column or wall near the toll stop position of the lane of a high-speed toll station. It has a normally open contact inside. When an object enters the detection range of the detection radar, the normally open contact will close. Since the detection radar is connected to the coil of the first relay, when the normally open contact inside it will close, the coil of the first relay will be energized, and the normally closed contact controlled by the coil will automatically disconnect. Since the induction coil circuit is connected in series with the normally closed contact of the first relay, when an object is detected by the detection radar, regardless of whether the induction coil is misjudged or not, and whether the circuit inside it is turned on or not, the entire drop-bar circuit will be guaranteed to be in a disconnected state, so that the barrier will not be energized and the drop-bar action will not be performed, ensuring that no car-smashing accidents will occur. Only when the induction coil has no detection, the normally closed contact inside it will resume closing, and at the same time, the detection radar has no detection, and the normally open contact inside it will resume disconnection, so that the coil of the first relay loses power, and the normally closed contact controlled by the coil resumes closing, can the entire drop-bar circuit be restored to the energized state, and then the barrier will perform the drop-bar action.

[0010] To sum up, by controlling the joint state of the detection radar and the induction coil circuit through the control relay, when the circuit device is connected, the barrier can only be lowered when it is determined that there is no vehicle in the toll stop position. The radar and the induction coil cooperate with each other to achieve a double insurance function, eliminating the risk of various types of vehicles being hit by vehicles and improving the safety of the barrier-dropping device at the highway toll station.

[0011] As a preferred embodiment of the present invention, the control device also includes a lifting rod signal source, a trigger controller and an alarm device; the control relay also includes a second relay connected to the lifting rod signal source; the trigger controller includes a positive trigger end, a negative trigger end and a built-in normally open contact; the positive trigger end is connected to the positive pole of the power supply, and the negative trigger end is connected to the normally open contact of the first relay, the normally closed contact of the second relay and the negative pole of the power supply in sequence; the alarm device is connected in series with the built-in normally closed open point of the trigger controller, and is connected to both ends of the power supply.

[0012] Therefore, since the barrier can only serve as a warning and blocking effect on vehicles when it is in the down position, but does not have the actual physical blocking ability to any vehicle or pedestrian, in reality, there are often cases where pedestrians arbitrarily pass through the barrier area and walk onto the highway, causing safety accidents.

[0013] The trigger controller is a relay that receives a trigger signal to close its internal normally open contacts. Its internal normally open contacts are connected in series with an alarm device and are connected to both ends of the power supply. When the normally open contacts inside the trigger controller are closed, the alarm device is electrically connected to the power supply, so that the alarm device is energized and then emits an alarm sound or light reminder to remind and warn newcomers. Among them, the positive trigger end of the trigger controller is connected to the positive pole of the power supply, and the negative trigger end is connected to the normally open contact of the first relay, the normally closed contact of the second relay and the negative pole of the power supply in sequence. When the blocking rod is in the blocking state, the photoelectric coupler connected to its lifting rod signal source will always output a low level, so that the normally closed contact of the second relay connected to and controlled by it will always remain closed; at this time, if the detection radar detects the reflected signal of a pedestrian passing by, the normally open contact inside the detection radar will be closed. Since the detection radar is connected to the coil of the first relay, when the normally open contact inside it will be closed, the coil of the first relay will be energized, and the normally open contact controlled by the coil will automatically close. At this time, the negative trigger end is connected to the negative pole of the power supply, so that the trigger controller obtains a low-level trigger signal, which in turn closes the normally open contact inside it, turns on the alarm device, and issues an alarm reminder.

[0014] By setting up a trigger controller to receive the trigger signal and then connect the alarm device, when the barrier is in a downed position and a pedestrian trespasses through the barrier and is detected by the detection radar, even if he is reminded by the sound and light signals, he will be prevented from entering the highway intersection and the occurrence of dangerous accidents can be avoided.

[0015] As a preferred embodiment of the present invention, a timer for setting the playing duration of the alarm sound is provided in the trigger controller.

[0016] Therefore, since the low-level trigger signal obtained by the trigger controller is instantaneous, in order to meet the conditions for the alarm device to fully warn pedestrians, it is necessary to send out an alarm signal for a period of time after the trigger is completed to fully remind pedestrians. At this time, a time period can be set by setting a timer for setting the length of time for setting the alarm sound playback. Within a period of time after the trigger is completed, the normally open contact inside the trigger controller is closed for a period of time to ensure that the alarm signal can be fully paid attention to and play the desired effect.

[0017] As a preferred embodiment of the present invention, the warning device includes a voice speaker for playing a warning sound and a warning light for emitting a prompt light.

[0018] Therefore, during the day, voice speakers are used to notify and remind pedestrians. At night, lights also have obvious recognition and reminder effects, and can produce more effective warning effects when combined with voice speakers.

[0019] As a preferred embodiment of the present invention, the timing duration of the timer is 3 to 7 seconds.

[0020] Therefore, a warning to pedestrians usually takes 3 seconds to ensure that they can hear the voice clearly. However, considering that it is often necessary to remind the attention of surrounding personnel on duty, appropriately extending the warning time can have a safer effect.

[0021] As a preferred embodiment of the present utility model, the voice speaker includes an external speaker arranged at the stop position of the toll station lane and a built-in speaker arranged in the toll station management center.

[0022] The external loudspeaker at the stop position of the toll station lane is mainly used to remind target pedestrians, while the built-in loudspeaker installed in the toll station management center can remotely remind management personnel and thus grasp the whereabouts of pedestrians in real time.

[0023] As a preferred embodiment of the present invention, the voice speaker includes a built-in memory, and the built-in memory is used to store recorded voice files.

[0024] As a preferred embodiment of the present invention, the warning device also includes a camera for automatically taking photos of pedestrians.

[0025] In summary, the utility model has the following beneficial effects:

[0026] 1. By controlling the joint state of the detection radar and the induction coil circuit through the control relay, when the circuit device is connected, the barrier can only be lowered when it is determined that there is no vehicle in the toll stop position. The radar and the induction coil cooperate with each other to achieve a double insurance function, eliminating the risk of various types of vehicles being hit by the vehicle and improving the safety of the barrier device at the highway toll station.

[0027] 2. By setting up a trigger controller to receive the trigger signal and then connect the alarm device, when the barrier is in a down position and a pedestrian trespasses through the barrier and is detected by the detection radar, even if he is reminded by sound and light signals, he will be prevented from entering the highway intersection channel to avoid dangerous accidents.

[0028] 3. The trigger controller has a delay function. By setting the time segment of the timer, it ensures that the trigger controller receives a trigger and the normally open contact can continue to be closed for a period of time, thereby ensuring the effectiveness of the alarm signal. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Figure 1 This is a circuit connection diagram of the control device of the barrier.

[0030] In the figure: power supply 1, induction coil circuit 2, detection radar 3, control relay 4, first relay 41, second relay 42, lifting rod signal source 5, trigger controller 6, alarm device 7. DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0033] like Figure 1 As shown, the power supply 1 serves as the power supply end of the entire control device and is used to power the detection radar 3. The induction coil circuit 2 is a circuit in the prior art and has a normally closed contact inside. When the induction coil detects a vehicle within the toll stop range, the normally closed contact is disconnected and the barrier is not energized, that is, the barrier does not drop. When the induction coil loses the detection target, the normally closed contact is closed again, the barrier is energized, and the barrier drops.

[0034] The detection radar 3 is an induction radar, which can be installed on a support column or wall near the toll stop of a highway toll station lane. It has a normally open contact inside. When an object enters the detection range of the detection radar 3, the normally open contact will close. Since the detection radar 3 is connected to the coil of the first relay 41, when the normally open contact inside it will close, the coil of the first relay 41 will be energized, and the normally closed contact controlled by the coil will automatically disconnect. Since the induction coil circuit 2 is connected in series with the normally closed contact of the first relay 41, when an object is detected by the detection radar 3, regardless of whether the induction coil is misjudged or not, and whether the circuit inside it is turned on or not, the entire drop bar circuit will be guaranteed to be in a disconnected state, so that the barrier will not be energized and the drop bar action will not be performed, thereby ensuring that no car-smashing accidents will occur. Only when the induction coil has no detection and its internal normally closed contacts resume closing, and at the same time, the detection radar 3 has no detection and its internal normally open contacts resume opening, causing the coil of the first relay 41 to lose power and the normally closed contacts controlled by the coil resume closing, can the entire drop bar circuit be restored to the energized state, thereby preventing the barrier from performing the drop bar action.

[0035] The trigger controller 6 is a relay that receives a trigger signal so that its internal normally open contact is closed. Its internal normally open contact is connected in series with an alarm device 7 and is connected to both ends of the power supply 1. When the internal normally open contact of the trigger controller 6 is closed, the alarm device 7 is electrically connected to the power supply 1, so that the alarm device 7 is powered, and then emits an alarm sound or light reminder to remind and warn newcomers. Among them, the positive trigger end of the trigger controller 6 is connected to the positive pole of the power supply 1, and the negative trigger end is connected in sequence to the normally open contact of the first relay 41, the normally closed contact of the second relay 42, and the alarm device 7 includes a voice speaker for playing an alarm sound and a warning light for emitting a prompt light.

[0036] The trigger controller 6 is provided with a timer for setting the duration of the alarm sound. In order to satisfy the sufficient warning conditions of the alarm device 7 to pedestrians, it is necessary to send out an alarm signal for a period of time after the trigger is completed to fully remind pedestrians. At this time, a time period can be set by setting the timer for setting the duration of the alarm sound. Within a period of time after the trigger is completed, the normally open contact inside the trigger controller 6 is closed for a period of time to ensure that the alarm signal can be fully noticed and play the desired effect. The timing duration of the timer is 3 to 7 seconds. For the reminder of pedestrians, usually 3 seconds is enough to ensure that they can hear the voice clearly, but considering that the attention of the surrounding working personnel is often reminded, the appropriate extension of the alarm duration can play a more secure effect.

[0037] The alarm device 7 includes a voice speaker for playing alarm sounds and a warning light for emitting a prompt light. During the day, the voice speaker is used to complete the notice and reminder of pedestrians. At night, the light also has an obvious recognition and reminder effect, and can produce a more effective alarm effect in conjunction with the voice speaker. The voice speaker includes an external speaker set at the stop position of the toll station lane and a built-in speaker set at the toll station management center. The external speaker at the stop position of the toll station lane is mainly used to remind the target pedestrians, while the built-in speaker set at the toll station management center can remotely remind the management personnel, thereby immediately grasping the whereabouts of pedestrians. The voice speaker includes a built-in memory, which is used to store recorded voice files. The alarm device 7 also includes a camera for automatically taking pictures of pedestrians.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
