Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parking lot management system technology, which is a gate opening / closing device for controlling entrance and exit of vehicles to and from a monthly contracted parking lot.

[0002]

2. Description of the Related Art Unauthorized use (unauthorized parking) at monthly parking lots (hereinafter referred to as parking lots) where only registered and contracted cars are parked, not a parking lot where an unspecified number of cars come and go
To prevent this, (a) a chain lift type gate opening / closing device or (b) a gate opening / closing device similar to the one used for railroad crossings (opening / closing by 1/4 rotation of the pole), It is provided at the entrance and exit. In addition, in order to identify whether or not the car has a contract, (c) Install an ID card and a disk or button-shaped device that can send and receive data in a part of the car body, and install these near the doorway. What is read by a reading device, and (d) remote control devices operated by parking lot users every time they enter and leave are used. The parking lot management system that is actually put into practical use is
It is a combination of the above (a) to (d).

[0003]

However, the prior art has the following drawbacks. First, as shown in FIG. 9, the (a) chain lifting type gate opening / closing device is relatively space-saving, small in size, and easy to install in an existing parking lot, but the chain 30 is driven by a motor. To raise and lower
There is no choice but to open and close for a long time. If an attempt is made to shorten the opening / closing time, the motor output has to be increased, and as a result, the column 31 becomes large. In order to incorporate a motor with a large output while keeping the size of the column 31 unchanged, the mechanism becomes complicated, such as changing the direction of the drive shaft.

Further, as one of the drawbacks of the chain elevating type, it is pointed out that there is a risk that a parking lot user may enter and exit by straddling the chain. In addition, when the chain 30 goes down, it is necessary to have a storage groove to store it, but it is necessary to carry out civil engineering work to install this and to discharge water and dust stuck in the storage groove. There are also drawbacks.

On the other hand, a circuit breaker such as (B) has a depth of 3
It has the drawback of being large, from 00 to 500 mm or more. This is a major obstacle when applied to existing small parking lots. For example, as shown in Fig. 10, the entrance is at a right angle to the road 32.
When there is 33, we usually allow parking up to the roadside to maximize the parking space. If a circuit breaker 34 having a large depth is installed in such an existing parking lot, as shown in FIG. 11, the parking space 35 on the side close to the road 32 becomes narrow and unusable. This means that when the circuit breaker 34 is installed in a small-sized parking lot, the number of parking lots will be smaller than before the installation, which is a serious problem for profit.

[0006] Next, when automatically controlling the entrance / exit of a car in a parking lot, it is necessary to recognize whether the entering / exiting car is a contracted car. As a way to do this,
As described in (c) above, there is a device in which an ID card, a disc-shaped or button-shaped device capable of transmitting and receiving data are installed in a part of the vehicle body, and these are read by a reading device provided near the doorway. For example, there is one that uses electromagnetic induction or reads data written in an ID tag by using microwaves.

[0007] In the case of the electromagnetic induction system, since it is possible to communicate only a distance of several tens of cm in principle, it is extremely difficult to read the data of the ID tag of a moving car by a reading device provided near the doorway, and especially in many types. It is virtually impossible to adapt to vehicle types (vehicle height and vehicle width differ).

On the other hand, in the microwave system, long-distance communication is possible, but it is expensive as a system and requires a wireless station license. (Even if a simple license is required, a technical standard conformance certificate must be obtained. In addition, it also has the biggest problems described below.

That is, the directivity, which is a characteristic of radio waves, is weak. That is, in the microwave method, as shown in FIG.
As shown in, the antenna 36 for receiving data at the entrance 33
In the case where the above is provided, the call from the car 37 trying to leave and the call from the car 38 trying to enter will be simultaneously received by the antenna 36. In order to improve this adverse effect, an antenna with a large aperture must be used, which leads to an increase in cost. In addition, even if the aperture of the antenna is increased to some extent, the microwaves are diffusely reflected by surrounding objects and re-enter the antenna. Therefore, it is difficult to distinguish the access from the entrance side and the access from the exit side.

Generally, to address this problem, FIG.
The method as shown in is used. That is, the circuit breaker
A loop coil 39 is buried under the ground before and after 34, a low frequency current is passed through this loop coil 39, and when a car, which is a large lump of metal, comes on this, the impedance of the loop coil 39 changes. Therefore, the loop coil 39 operates as a metal detector and can detect the presence or absence of a car on the loop coil 39. By this loop coil 39, it is possible to know whether there is a car trying to enter or there is a car leaving, so by combining this information with the transmission from the above car,
It is possible to know which direction the vehicle is coming from, and it is possible to identify the above-mentioned direction of access.

However, this loop coil 39 cannot be buried in a road which is generally a public road, and if a loop coil is used, as shown in FIG. There is no choice but to install it in a slightly recessed place, and it cannot be a solution to the sacrifice of the existing parking space already discussed. As long as the loop coil 39 is used, the same thing can be said for the chain lifting type gate opening / closing device.

The other method is to use a so-called remote control unit, which is a remote control using infrared rays or radio waves that is manually operated by a car driver.
As for the radio wave, the directivity is weak as mentioned above. Infrared rays are already widely used in TVs, videos, and other home appliances, and are cheap. Therefore,
It seems that the use of this device serves the most purpose. However, the purpose of the inventors is simple operation when the driver operates the remote control unit.
And it is possible to send a lot of identification data.

On the other hand, the current remote control unit is
Since only the data of 1 to 12 points is sent,
For example, to send the data 34, the pushbuttons 3 and 4 must be pressed, and the pushbuttons indicating "send" or "setting complete" indicating the completion of the setting data must be pressed. Now, if you want to manage multiple parking lots using the same remote control unit, for example, you can park 100 cars in one parking lot, and from 1 to 4000 for 40 to 50 parking lots. It is necessary to set the number from ~ 5000 to each car. If you do not set an individual number for a car, you will be able to use it even in a parking lot where you do not have a contract with one remote control unit. In such a case, in the remote control unit as described above, the number of digits of the setting number, that is, the push button has to be pressed four or five times, which is troublesome and error-prone.

In this connection, there is another problem with the existing system. As mentioned above, in a system using a one-touch input remote control unit, a unique code is set for the parking lot, and all users there use the same code. After entering the parking lot by car, you can walk out of the parking lot with the remote control unit and use the remote control unit in another car to enter the parking lot again. In order to prevent this double parking, it is necessary to give each remote control unit an individual code, that is, an ID number.

The present invention has been made to solve the above-mentioned problems, and an ID number can be input with one touch without narrowing the existing parking space, and based on this, illegal parking and double parking can be prevented. The purpose of the present invention is to provide a gate opening / closing device for use at the entrances and exits of parking lots, factories, etc.

[0016]

According to the present invention, in a gate opening / closing device of a breaker type, the ID number transmitted by one-touch from a remote control unit storing an ID number set for each vehicle is used as a gate opening / closing device. It is characterized in that it is received by a reception unit provided and the gate is opened and closed.

Further, when the vehicle enters, the receiving unit provided in the gate opening / closing device stores the received ID number, and after confirming that the vehicle has exited, the vehicle with the same ID number is entered. The feature is that heavy parking is prevented.

The depth of the gate opening / closing device is 150 mm.
The gate opening / closing device is characterized in that:

[0019]

Embodiments of the present invention will be described below. FIG. 1 is a view showing a mechanism of a gate opening / closing device according to the present invention. The gate opening / closing device 1 is provided with receiving portions 3 for receiving a transmission from the remote control unit 2 capable of transmitting a large amount of setting data (ID number) with one touch, on the entrance side and the exit side of the parking lot. The data received by the receiving unit 3 is sent to the controller 4,
Checked according to the flow chart described later, and if you can enter, "open gate" from controller 4
Is sent to the motor 5. The motor 5 rotates in response to the "gate open" command, and the pulley 7 is rotated via the speed reducer 6. The rotational force of the pulley 7 is transmitted to the pulley 9 via the belt 8 to operate the pole 10 directly connected to the pulley 9 to open the gate. The pulleys 7 and 8 may be replaced with sprockets and the belt 8 may be replaced with a chain.

After this, the sensor provided in the gate opening / closing device 1
The passing of the vehicle is detected by 11, and the passing of the vehicle is sent to the controller 4. The controller 4 sends a command of "gate close" to the motor 5 to operate the pole 10 in the same manner as "gate open", Close the gate. Attach the striker 12 to the pulley 9, and use this striker 12 to perform the limit switch.
13 and 14 are actuated to stop the pole 10 at a predetermined position. Information transmission such as "reception In", "reception Out", "not admitted", "expired", and "failure" to the user is performed by a display lamp 15 provided on the upper part of the gate opening / closing device 1. These devices are incorporated in a housing 16 to form a gate opening / closing device 1, and the gate opening / closing device 1 is fixed to the ground 17 at the entrance of the parking lot.

FIG. 2 is an external view of the gate opening / closing device 1.

State.

FIG. 4 is a view showing the mechanism of the remote control unit 2 used in pair with the gate opening / closing device 1 according to the present invention. By pushing a push button (switch) 24, the microcomputer 25 reads the data of the memory 23 in which the setting data is stored in advance, and sequentially encodes or modulates the data to convert it into a serial signal and sends it out. This signal is amplified by the amplifier 26, converted into infrared light by the light emitting diode 27, and transmitted. A battery (not shown) is used as the power source of the remote control unit 2. Although it is not absolutely necessary to use the microcomputer 25, the one-chip microcomputer including the memory 23 was used here. Further, a laser diode having a sharp directivity and a large light output may be used as the light emitting diode 27. In this way, it is possible to provide a remote control unit that can be placed on the palm at low cost.

FIG. 5 is a plan view when the gate opening / closing device 1 according to the present invention is installed at the entrance of a parking lot. Normal,
The perimeter of the parking lot is surrounded by net fences or concrete blocks, the foundation of which is concrete block 28 in each case. According to JIS standards, concrete blocks have a thickness of 100 mm or 150 mm, and the latter with a thickness of 150 mm is often used near the entrance. Therefore, the depth of the gate opening / closing device 1 (W in Fig. 2 (b))
If the height is 150 mm or less, as described at the beginning, when installing in an existing parking lot, it is not necessary to sacrifice the existing parking space. Also, the sensor 11, which is a vehicle passage detector,
By using the photo sensor, the reflection plate 29 is installed at a position facing the sensor 11, so that the sensor 11 and the reflection plate are
The existence of a car can be known by the existence of an object that blocks the optical path between 29.

The movement of the gate opening / closing device 1 when the vehicle enters and leaves the parking lot will be described with reference to the flowcharts of FIGS. FIG. 6 is a flowchart when the car exits the parking lot, FIG. 7 is a flowchart from the gate opening to the gate closing, and FIG. 8 is a flowchart when the car enters the parking lot. As shown in FIG. 6, if the receiving unit 3 of the gate opening / closing device 1 receives the information from the remote control unit 2 owned by the user and the car enters the parking lot, the process jumps to the flowchart of FIG. If the car leaves the parking lot
The "t" lamp is lit on the display lamp 15 of the gate opening / closing device 1. Next, the 5-digit ID data (the ID number set in the car) is read to determine whether or not the car is a registered car. If the car is not a registered car, the "Reception Out" lamp is turned off, and the process returns. In the case of a registered vehicle, as shown in FIG. 7, the gate is opened, the passing state of the vehicle is read by the sensor 11 of the gate opening / closing device 1, and the gate is closed after t seconds after the passing of the vehicle is completed, Next, as shown in FIG. 8, Flagnn
Is replaced with 0 (the car has left the parking lot) and "Reception Ou
Turn off the "t" lamp. Then, the presence / absence of the ID interrupt input is determined, and if there is no ID interrupt input, the process returns to the original state, and the movement of the gate opening / closing device 1 when the vehicle exits the parking lot is completed at this point. The value of t seconds is a number of seconds suitable for each parking lot.

As shown in FIG. 6, if there is an ID interrupt input indicating that the car will enter the parking lot, the process jumps to FIG. 8 and, as shown in FIG. 8, the "reception In" lamp is lit on the display lamp 15. .
Next, the 5-digit ID data is read to determine whether or not the vehicle is a registered vehicle. If the vehicle is not a registered vehicle, a "no entry" lamp is lit on the display lamp 15, and the process returns. In the case of a registered vehicle, it is further determined whether or not the contract has expired. If the contract has expired, the "expired" lamp is lit on the display lamp 15 to notify the driver of the expiration. Next, Flagnn
Is 0 (the relevant car is not in the parking lot), and if it is not 0 (the relevant car is in the parking lot), the "not admitted" lamp is lit on the display lamp 15, and the processing is based on the original. Return. When Flagnn is 0, the process jumps to FIG. 7, and the gate opening / closing device 1 makes the same gate opening / closing operation as when the vehicle exits. When the gate closes, set Flagnn to 1
Replaced with (the relevant car is in the parking lot) and "Reception In"
The lamp of is turned off, and the process is restored. At this point, the movement of the gate opening / closing device 1 when the car enters the parking lot is completed.

By the above processing, it is possible to check whether the vehicle is a registered vehicle or the contract has expired, and prevent double parking.

[0028]

As is apparent from the above description,
Since the gate opening and closing device according to the present invention is thin with a depth of 150 mm or less, it does not narrow the parking space even if it is installed in an existing parking lot, and no additional work such as burying a loop coil is required. It is also easy and does not inconvenience the user during this time. Since the user can input the ID number with one touch, the operation of the remote control unit is easy, and since individual cars can be managed, illegal parking and double parking can be prevented. Furthermore, even if an unforeseen situation such as a power failure or failure occurs, the gate can be opened by the user's key, so that the user is not inconvenienced.
