The present invention relates to a parking fee settlement method, and more particularly, to a method of automatically calculating a parking time after entering a parking lot and then calculating a parking fee based on the actually measured parking time.

Today, cars are not just transportation, but are owned by almost all adults and are becoming a popular means of enjoying cultural life. People use cars for personal cultural or public life, such as traveling, shopping, watching movies or theatre, eating out, or traveling. While driving, the car runs on the road, but if you are not driving, you must park at the designated place. If the parking space is private or public, you must pay a certain parking fee.

In paying the parking fee, it is generally based on "time". Therefore, how to measure and settle time is considered a very important issue. It is inconvenient and difficult to guarantee objectivity because the parking manager directly calculates the time when the parking starts and the time when the parking ends. In order to ensure objectivity and accuracy, a parking record card is issued, but for this purpose, there is a problem in that a machine for issuing a parking record card must be provided separately, and garbage is produced every time a parking record card is issued. .

The object of the present invention is to provide the simplest and most accurate parking fee settlement method.

Basically, based on how two clocks are used to regard the difference in time indicated by each clock as parked time, one clock should pass as if it were a normal clock and the other clock would be parked. If you stop for a while, the difference between the two clocks is the total parking time. Since the problem becomes very inconvenient to operate the clock to stop according to the parking, the technical problem of the present invention is set to provide a means and a method for automatically detecting that the driver is parked instead of driving.

In order to achieve the above object, the present invention, the step of entering the car parking lot parking area; Turning on a switch of the sensor clock device installed in the vehicle; Stopping the first clock of the sensor clock device and operating a detection sensor; Determining whether a detection event is generated by the detection sensor, if a detection event occurs, proceeding to the next step, and repeating the previous step if a detection event has not occurred; When a detection event occurs, the relationship between the number of detection event occurrences N and the number N _o predetermined by the control unit of the sensor clock device within a predetermined time T _o is "N≥N _o ". Whether or not, and if "N≥N _o ", proceeds to the next step, and if "N <N _o ", repeating the previous step; Reactivating the first clock when the detection event occurrence count N satisfies "N≥N _o "; Comparing time information of the first clock with time information of a second clock used as a reference clock; And calculating and paying a parking fee based on the difference between the times of the first clock and the second clock obtained by comparing the time information.

In a preferred embodiment, the T _o is 60 seconds and the N _o is preferably 3 to 5 times.

In addition, the detection sensor of the present invention is a human body detection sensor, or the detection sensor is preferably a sensor for detecting the engine vibration or noise of the vehicle.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, when it is determined that the subject matter of the present invention may be unnecessarily obscured by those skilled in the art such as related well-known functions or known configurations, the detailed description thereof will be omitted.

1 schematically illustrates a driver detection method using a human body sensor 1 in an embodiment of the present invention.

If the driver parks the car in the parking lot, no one is in the vehicle because the driver is out of the vehicle. In other words, it can be considered that there is no movement inside the vehicle. Therefore, if the human body detecting sensor 1 is installed in the car, the human body cannot be detected when parking. The human body sensor 1 is a pyroelectric infrared sensor. When the ferroelectric receives infrared rays, the human body absorbs heat energy and causes a change by spontaneous polarization, and a charge is induced on the surface in proportion to the change amount. By using the principle that the pyroelectirc effect occurs, a small amount of infrared rays generated from the human body are detected.

The human body sensor 1, which is an infrared sensor, sets and detects the vicinity of a driver's seat as a detection area through an optical lens.

2 shows a schematic configuration of the sensor clock device of the present invention in which the human body sensor 1 is installed. This sensor clock device is installed at a specific location in the vehicle to have the above-mentioned sensing zone, and allows the terminal energy to be transferred from the sensing zone.

The terminal energy entering the human body sensor 1 is amplified by the amplifier 3, and the output signal is output through the comparator 4. At this time, the amplifier 3 has a bandwidth limited to 10 Hz to prevent high frequency noise, and the comparator 4 responds to the + and − displacements of the sensor output signal. The configuration of the human body detecting sensor 1 is typical and is well known in the sensor technology field.

The present invention transmits the output signal of the human body sensor 1 to the microcomputer control unit 5 of the present invention, the microcomputer control unit 5 is a timer circuit (in accordance with a predetermined order based on the sensor output signal) 7) to control the operation. On the other hand, the switch 6 turns on / off the operation of the sensor clock device and resets the time displayed by the timer circuit 7 through the light emitting device to the reference time.

FIG. 3 is an embodiment in which the embodiment of FIG. 1 using the microcomputer control unit 5 is modified into a general logic circuit. Logic circuits using multiple counters have the same effect but have advantages in terms of price and low current. The input analog signal circuit is the same and consists of a clock oscillator, divider, second counter, minute counter, hour counter and latch circuit, and if the detection event is not received by inputting the detection sensor, The running time is not displayed on the indicator. When a detection event occurs through the detection sensor, the counter time is displayed on the indicator. It can be understood that the control unit in this embodiment is composed of a plurality of counters and latch circuits.

4 is an embodiment in which the human body sensor uses a vibration sensor of the engine instead. Engine vibration is transmitted throughout the vehicle because the engine is always moving when the vehicle is starting. Therefore, the magnet 8 and the coil 10 supported by the resilient material 9, such as spring, rubber, silicon, etc. are used to detect the minute vibration caused by the engine vibration. When the magnet 8 moves in accordance with the engine vibration of the vehicle, electromotive force is generated in the coil 10. If the signal is amplified by the amplifier 3 and the vibration frequency 11 from the engine is filtered through the filter 11 to compare and analyze the signal, it is possible to determine whether the vehicle is started. The sensing event generated by the vibration sensing sensor displays the time by a method predetermined by the indicator 13 via the logic circuit 12. The specific time display method is the same as the embodiment of FIGS. 1 to 3.

In the above, as the sensor, a human body sensor and a vibration sensor were used. In another embodiment, a sound sensor may be used. It is a method using a commonly used microphone (dynamic mic). The microphone, which is a voice receiver that combines a magnet and a coil, has a sound plate and a coil coupled to a fixed magnet. If a dynamic microphone is installed at a specific location near the car dashboard, the engine sound is delivered to the dashboard when the car is started, and the signal can be amplified, filtered and compared to determine whether the car is started.

5 illustrates a method of calculating the difference between two times using two clocks in accordance with the present invention. "Clock 1" means a clock connected with the timer circuit 7 of the sensor clock device installed in the vehicle, and "Clock 2" means a clock indicating a standard time as a reference clock. "Clock 2" is a clock that represents the standard time, so even if there is a slight error, it can be said to display the same time regardless of who's watch, such as the parking lot manager's watch, the driver's watch, or a third party's watch. .

For example, when the driver gets out of the vehicle and starts parking, the "Clock 1" is controlled to stop, and since the human body sensor 1 of the sensor clock device does not generate any sensing event, the stopped time is The current time of "Clock 1" (where "present" can be defined as the time when the parking fee is settled) is delayed because the parking is completed and the operation continues until the stop time during the parking. (15:00) can be compared with the standard time (16:12) indicated by "Clock 2", and the time difference "1 hour 12 minutes" is the parking time. Parking fees are charged for this "1 hour 12 minutes".

6 shows a configuration of a parking fee settlement process according to the embodiment of the present invention.

First, the car enters the parking lot and is located in the parking area to be parked. When the parking is completed in the parking area, the switch of the sensor clock device installed in the vehicle is turned on according to a predetermined method (S10). As described above, the sensor clock device includes a sensor circuit including a sensing sensor, an amplifier, and a comparator, and is composed of a controller (microcomputer or logic circuit), a timer circuit, a switch, and the like. The first clock (Clock 1) made of a light emitting device is exposed to the outside by being electrically connected to the timer circuit by one or two numbers, and can sense the vicinity of the driver's seat, for example, in front of the driver's seat inside the vehicle. Or it is installed in the position of the front side. The method of switching on the sensor clock device is predetermined. This may be determined as an automatic operation based on an event such as a door of the vehicle being closed and a car key being pulled out, or may be determined as a manual operation by a user's operation.

When the sensor clock device is operated, Clock 1 is stopped, and the detection sensor starts to operate to detect vibration or noise of a human body or a vehicle (S20).

The detection sensor operates around the driver's seat, and detects whether a detection event that the sensor responds to, such as movement of the human body, occurs. Sensing sensors do not need to accurately detect, analyze and react to all the minute changes inside and outside the car. Based on the value predetermined as the sensor chip characteristic, it is determined whether any change is recognized as the movement of the human body, that is, whether a sensing event such as vibration or noise of the human body or the vehicle has occurred (S30). If no detection event occurs, sensing will continue and Clock 1 will continue to stop.

For example, since the movement of the human body and the infrared radiation are continuously performed, a sensing event that can be defined as the occurrence of the human body or the movement of emitting infrared rays of a size similar to the infrared radiation emitted by the human body may also be continuously recorded. Therefore, all events that occur at a certain time interval (eg within a few seconds) are considered the same event. This is also the case when sensing using vibration or noise of the car.

When a sensing event occurs as a result of sensing, it is necessary to more accurately determine whether the sensing event is a human body sensing event of a driver who wants to drive after parking. An accidental detection event may occur when an accidental detection event occurs, for example, when a pedestrian passing by the vehicle briefly looks inside the vehicle in which the sensor clock device is operating. This is especially true when the car window being parked is open. This is also the case when a driver stops by at a parked car to take his luggage in the car.

Therefore, when a detection event occurs, the number of detection event occurrences (N) is counted within a predetermined time (T _o ), and then the number of times (N _o ) preset by the control unit of the sensor clock device is compared with each other. If N is equal to or greater than N _o , then a true detection event is considered to occur, but if N is less than N _o , a detection event that occurs by accident, rather than a detection event that indicates parking termination, or It is regarded as a detection event that is not intended as the end of parking (S40).

That is, it is determined whether or not the relationship of "N≥N _o " is established, and when it is "N≥N _o ", it progresses to the next step, and when "N <N _o ", the previous step is repeated.

On the other hand, in the preferred embodiment, the predetermined time interval T _o is 60 seconds, and N _o is preferably 3 to 5 times. For example, if four sensing events occur within one minute, the driver may start or consider driving. Even a decent driver can move about four times a minute.

Next, when the number N of occurrences of the detection event is greater than or equal to the number N _o preset by the controller of the sensor clock device, the driver is assumed to have started driving the car by sitting in the driver's seat of the car. , Restart Clock 1 which is stopped (S50).

Then, the time information indicated by the clock 1 which has started to move again is compared with the time information of Clock 2 which is a reference clock indicating the current standard time (S60). Clock 2 has never stopped because it represents standard time, but Clock 1 has been stopped for the amount of time parked, so there is a "lag" between the clocks. This is the same as already described in FIG.

Finally, the parking fee is calculated and paid based on the time difference between Clock 1 and Clock 2 obtained by comparing the time information (S70).

The above embodiments add that it does not limit the scope of the claims.

An effect of the present invention is that the parking fee can be accurately calculated through a simple and inexpensive sensor clock device.

It is economically advantageous because there is no need for a separate parking lot manager's settlement machine, a separate in-vehicle device, and a parking time record card that is repeated every time.

In addition, the sensor can accurately measure the actual time parked and increase the objectivity of the parking fee.

In addition, the unique effects that occur due to the unique structure of the present invention are not only described in the above-described embodiments and claims of the present invention, but also in a broader range due to the effects that can easily occur within the range easily conceivable therefrom. Add that it will be included.
