The parking guidance system senses the presence / absence of a vehicle entering / leaving the parking space by visually showing the vacant parking area to the driver so that the user can easily find an empty parking space, while informing the parking lot of the parking lot. By detecting the entrance and departure of the vehicle by arranging the vehicle detection sensor in the parking area, it is possible to easily manage the parking lot by making it possible to grasp at a glance, and the entrance or departure information of the vehicle is transmitted to the control station through the wired or wireless network do. It is common for the control station to be operated by manned or unmanned and to pay the parking fee.

On the other hand, there is an increasing need to build a more compact disaster prevention system in order to secure the safety of the public due to the lack of an early detection and alarm system in recent earthquakes in Korea. There is almost no earthquake detection sensor in living space, so it is urgent to supply earthquake sensor and alarm system. In the United States, an earthquake detection app was developed, but it provides an early warning of earthquakes in the sense that an earthquake can only be detected when there is a mobile device on a flat table and that the earthquake can be detected more quickly on the ground It is not enough to do.

Further, in the case of an outdoor parking lot, there is a problem that it is not easy to install a power line. Therefore, in order to operate both the sensor and the communication module, it is difficult to precisely check the parking situation when the battery is discharged due to the battery consumption, making it difficult to form a reliable parking guidance system. That is, since the battery condition must be constantly checked and the battery must be recharged or replaced before the battery is completely discharged, the outdoor parking lot is having a lot of difficulty in actually constructing the parking induction system.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a parking guidance system installed in a parking lot by combining an earthquake and vibration detection sensor to provide an early warning of an earthquake along with parking guidance of a vehicle, And to apply wireless communication to the system so that it can be installed in an outdoor parking lot at the same time.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

4 shows a configuration of a parking induction system having an earthquake and vibration detection sensor according to the present invention.

A sensor module including both a vehicle sensor and an earthquake sensor and a position guidance module are installed in each parking space of the parking lot, and an alarm module is connected to the sensor module. Both are connected to the control system so that data can be collected and controlled from the sensor module and the location guidance module installed in each parking zone.

The sensor module and the position guidance module are connected to the solar cell, and the power is supplied by the battery and communicated wirelessly with the control system. The wireless communication means may be a ZigBee, and the network may be configured in a mesh manner.

The sensor module and the position guidance module are installed independently of each other without wiring, and each of them is supplied with electric power by a battery. In order to prevent the management inconvenience caused by frequent battery replacement, solar cells are installed in each parking area with each sensor module and position guidance module.

The control system includes a sensor control module (SCM), a central control module (CCM), a monitoring server, a monitor and a warning system, and an LED display device may be added. The LED display device may be in the form of an electric panel, and the LED electric signboard may be replaced by another display device such as an LCD panel.

The sensor module and the position guidance module form a first data interface through the ZigBee and are connected to the sensor control module, and the sensor control module and the central control module form a second data interface. The data interface has a function of transmitting and receiving data. The first data interface can be installed in a place where wiring work is not easy, such as an outdoor parking lot, by applying a communication method of exchanging signals wirelessly.

The second data interface is capable of wired or wireless communication. Since the sensor control module and the central control module can be built together with the control server, the electric power is supplied by wire, and the communication method is also required, so there is no need to use the wireless.

The central control module receives both the data of the vehicle sensor and the data of the earthquake sensor from the sensor control module, collects them, and transmits them to the LED display device and the monitoring server. The monitoring server is connected to the monitor and earthquake warning system, and displays the parking status of the vehicle received from the central control module on the monitor. If there is an alarm notification command in response to an earthquake, the monitoring server activates an earthquake warning system so that it emits an emergency bell or warnings such as a warning light and / or voice guidance.

Also, even if an earthquake and vibration sensor always monitors whether or not an earthquake occurs, when an administrator intends to check whether or not a seismic wave is detected by an earthquake sensor, if the user inputs an instruction to transmit seismic data through a monitoring server, According to this command, the sensor control module receives the stored data and transmits it to the monitoring server or the earthquake warning system. The seismic data is recorded / stored and displayed as a vibration graph of the waveform of a seismic wave such as P wave and S wave. The seismic waves appear when an earthquake occurs and the waveforms according to the vibration that may be in the normal state are recorded / stored. Accordingly, in addition to the occurrence of an earthquake, various vibrations such as vibrations caused by surrounding construction and vibrations caused by passing a heavy vehicle can be detected and recorded / stored. Such vibration sensing data can be used for vibration exposure of a parking lot or a building, safety condition check, etc. in addition to an earthquake.

The sensor module, which is powered by a solar cell-powered battery, has a main processor, a vehicle sensor connected to it, an earthquake and vibration sensor, and LEDs for indicating conditions such as vehicle presence. The main processor transmits and receives data to and from the sensor control module via the ZigBee. The main processor has a transmission terminal and a reception terminal, and forms a first data interface through a data bus.

The vehicle sensor of the sensor module senses the presence of the vehicle, displays the presence or absence of the vehicle by turning on the LED, and the earthquake and vibration sensor continuously detects the vibration. If there is a vehicle in the surveillance area, it is possible to light up the LED like red and empty if it is green.

6 shows the configuration of the sensor control module.

The sensor control module has a main processor, a memory connected thereto, a coprocessor, and a status display LED. The main processor includes a transmission terminal, a reception terminal, and a data bus connected to the sensor module, the transmission terminal constituting a first data interface for exchanging data with the sensor module, and a separate transmission Terminal and a receiving terminal and a data bus to which they are connected. In addition, the sensor control module has a memory for recording and storing vibration and seismic data sent from a sensor module that continuously detects earthquakes and vibrations. Vibration and seismic data are recorded in the form of waveforms, transmitted at the request of the controller through the central control module, and the transmitted data can be displayed as a waveform graph on the monitor. The LED for status indication indicates the use state, that is, during operation or failure without failure, and indicates the smoothness or non-communication state of the communication state.

The operation of the parking guidance system according to the present invention is as follows.

Vehicle detection, vibration, and earthquake detection are simultaneously performed in the sensor modules arranged in each parking area. In normal times when an earthquake does not occur, data pertaining to vehicle detection, that is, presence or absence of vehicles in the monitoring area, is sent to the sensor control module The main processor of the sensor control module collects the data from each sensor module and transmits it to the central control module. The vibration and earthquake sensor continuously detects the vibration and sends it to the sensor control module, and the waveform graph about the time axis is recorded / stored in the memory of the sensor control module. Therefore, when necessary, vibration and seismic detection records can be retrieved and viewed on the monitor to detect vibration or seismic conditions.

The central control module collects the status of the parking lot through the parking data received from the sensor control module and displays the parking status on the monitoring server and the LED display device. That is, the parking lot status is displayed in the form of a diagram, a table or a photograph on the monitor connected to the monitoring server so that the status can easily be determined in the control station. The LED display allows a simple form of sign, such as a schematic or number of parking spaces, at the entrance of the parking lot. If the parking lot is several layers, the display device is installed at the entrance of each floor to display the floor parking status (fullness, the number of parking spaces, arrow route guidance to the parking zone, etc.) You can install and display the current status of the line. However, the LED display device can perform the same function even if it is replaced with a display panel such as an LCD. The memory of the sensor control module stores signals of the vehicle detection sensor and the earthquake detection sensor, and when the search command is inputted and transmitted from the central control module, the memory detects and transmits the search command.

When an earthquake is detected in the sensor module, an earthquake signal indicating the occurrence of the earthquake is immediately transmitted to the sensor control module. When the sensor control module receives the earthquake signal, it switches to the earthquake data receiving mode, Collects and transmits an earthquake warning to the central control module, and operates the earthquake alarm module included in the sensor module to display an earthquake situation. The earthquake alarm module included in the sensor module can be configured to issue an earthquake voice announcement to notify people in each parking space of an earthquake occurrence, or to display an emergency situation with an emergency bell alarm or an illumination indicator.

When the central control module receives an earthquake warning, it activates the alarm system and causes the monitoring server and the LED display to display an earthquake warning message. The seismic alert may include a message display on the monitor screen and the LED display and a voice alert. That is, it can include ring tones, voice guidance, etc., and can be operated together with a warning light.

The alarm system also analyzes and monitors the seismic data and alerts the building where the parking lot is located.

The monitoring server analyzes and continually monitors the seismic data

While the earthquake occurrence situation continues, the sensor module continuously sends the earthquake signal to the sensor control module, and the sensor control module continues the earthquake data reception mode. Therefore, the parking status is not displayed on the monitor and LED display device, Only.

In addition, the existing emergency bell installed in the parking lot generally operates in conjunction with the earthquake warning system.

When no further earthquake is detected from the earthquake sensor, the sensor control module determines that the data received from the earthquake sensor is not an earthquake, and accordingly issues an unlock command to release the earthquake data receiving mode, So that the vehicle detection sensor is activated and vehicle detection is performed.

The earthquake detection sensor can be composed of an acceleration sensor, and it is possible to set threshold data beforehand or to record a seismic wave sample in case of reaching a seismic wave. Accordingly, the earthquake occurrence system is activated by judging the occurrence status of the earthquake against the reference data.

When a command is input through the monitoring server, the center control module transmits the command to the sensor control module. When the command is input from the monitoring server to the sensor control module, And transmits the data to the monitoring server or the earthquake warning system. Therefore, information about an earthquake can be detected at any time. Such seismic data are displayed in waveform as time passes as described above.

The parking induction system can be installed with no solar cell in the outdoor parking lot without wiring, so it is very convenient to construct, and it is possible to promptly detect earthquakes and alert them promptly.

It is to be understood that the invention is not limited to the disclosed embodiment, but is capable of many modifications and variations within the scope of the appended claims. It is self-evident.
