传统的一体式超声波探测器是安装在每个车位正上方，这样安装的弊端是一体式探测器所集成的指示灯容易被停车场的立柱挡住。而采用前置式超声波车位探测器，探测器集成指示灯安装在车位的正上方，避免了指示灯被立柱遮挡的情况出现。
The traditional one-piece ultrasonic detector is installed directly above each parking lot. The disadvantage of this installation is that the indicator light integrated by the one-piece ultrasonic detector is easily blocked by the column in the parking lot. By using a front-mounted ultrasonic parking space detector, the detector integrated indicator is installed directly above the parking space, avoiding the situation that the indicator is blocked by the column.
前置式超声波车位探测器的超声波发射模块里独特的超声波发射探头，使得探测更稳定，成功率高达99.9%。超声波发射探头中间的发射探头和所述的超射波接收探头与水平面的整体角度呈最佳角度，解决了普通探测器因个别车辆停放不到位而检测挡风玻璃信号不稳定的问题。
The unique ultrasonic emission probe in the ultrasonic emission module of the front-mounted ultrasonic parking detector makes the detection more stable and the success rate is as high as 99.9%. The transmitting probe in the middle of the ultrasonic transmitting probe and the ultrasonic receiving probe have the best angle with the whole horizontal plane, which solves the problem that the ordinary detector detects the instability of the windshield signal due to the inadequate parking of individual vehicles.
因为该探测器与传统设计的不同，有效降低车位的设备成本和施工成本，有效减少施工时间。
Because the detector is different from the traditional design, it can effectively reduce the equipment cost and construction cost of the parking space, and effectively reduce the construction time.
