Description

Integrated sensor for parking lot ramp and vehicle entry warning method using it The technical field of this invention is the field of convergence technology between architecture and IT. A safety system is widely used to prevent accidents by notifying the opposite entrance or nearby pedestrian walkways when a vehicle enters a parking ramp from one side. This system includes a loop coil embedded in the road surface, a control device, and lighting/speaker units connected to it via wires. The loop coil is a device that detects changes in impedance caused by the passage of a vehicle. When the loop coil detects a change in impedance, it uses this signal to control the control device, thereby operating the lighting and speakers. Here, loop coils are buried beneath the road to prevent damage caused by heavy vehicles. Galvanized cables are primarily used for durability. These loop coils have the advantage of low installation costs and are not directly affected by the external environment, but they have the disadvantages of low accuracy and difficult maintenance. Specifically, even if buried beneath the road, durability may be weakened by continuous vehicle weight. If the road has low moisture resistance or permeability, detection accuracy may be significantly reduced by external moisture. Since impedance can change due to causes other than vehicles, installation must be performed without reinforcing bars or metal objects near the coil to prevent this. Additionally, in the case of roads within buildings (underground parking lots, parking towers, etc.), malfunctions may occur due to reinforcing bars within the slab, so the slab reinforcement must be checked. In addition, since it is buried beneath the road, the installation process is cumbersome, and in the event of a malfunction or other problems, the road must be excavated and the burial work performed. In addition, the presence of devices capable of distorting the frequency around the control unit or loop coil must also be checked.

FIG. 2 conceptually illustrates the structure of an integrated sensor assembly according to the present invention. FIG. 3 is a flowchart illustrating a warning method according to the present invention. Hereinafter, a method according to the present invention will be described with reference to the drawings. 1. Description of the System The integrated sensor according to the present invention is a device that integrates a function for detecting the entry of a vehicle, lighting such as a warning light, a speaker for outputting a warning sound, and a wireless communication function. Multiple integrated sensors are installed, and each of them can communicate wirelessly. In addition, the integrated sensor according to the present invention is installed facing the road from the side wall or column of a parking ramp as shown in FIG. 1. Accordingly, it receives power by being connected to a power source that is easily connected to the side wall or column. Since it is not buried in the road like conventional loop coils, there is no need to bury power lines or communication lines inside the road. Therefore, the possibility of failure caused by vehicles traveling on the road is significantly reduced, and there is no need for separate road burial work during installation or road excavation for maintenance. As shown in FIG. 1, the integrated sensor according to the present invention is preferably installed in two rows based on a road where a vehicle travels back and forth. Of course, in the case of a road where a vehicle travels in one direction, it is not necessary to install it in two rows. In this specification, the integrated sensors are described under the assumption that they are installed in two rows, a first row and a second row, on a parking ramp. A total of n integrated sensors may be installed in each row at regular or irregular intervals, each referred to as the nth integrated sensor, and the unique number of the integrated sensor increases in the direction of travel of the vehicle. Accordingly, the integrated sensors in each row may be referred to as the nth integrated sensor in the first row and the nth integrated sensor in the second row (where n is a natural number greater than or equal to 2), and may be denoted as S11 to S1n and S21 to S2n. As shown in FIG. 2, one integrated sensor includes a lighting unit (10), a speaker (20), a control unit (30), a microwave (MW) sensor module (40), a communication unit (50), and a power supply unit (60). The lighting unit (10) receives a warning signal and emits light to warn of vehicle entry. The speaker (20) also receives a warning signal and outputs a warning sound to warn of
