[0002] At present, the detection equipment for parking fee management in the industry is mostly two-mode geomagnetic "geomagnetic + radar", but with the further promotion of wisdom parking projects, the related two-mode geomagnetic is difficult to further improve the use efficiency due to the following problems: 1. In rainy and snowy weather, the radar is prone to malfunction due to water and snow covering the surface shell, resulting in a sharp decline in vehicle detection effect; 2. For various types of vehicles and various parking postures, the radar always has a detection blind area and appears malfunction, which also needs manual processing in the background; 3. In order to avoid being soaked by water when it rains, the related products are artificially made to protrude 4-6 cm above the ground when installed on the ground, but this is prone to tripping and falling and causing accidents; 4. When the existing two-mode geomagnetic is applied to left and right side-by-side non-alphabet parking spaces, the vehicles are very close to each other, and the magnetic field overlap and crosstalk between them are more prominent than before and after the one-dimensional parking space. In the case of radar malfunction, the probability of false judgment by magnetic field detection alone is also higher; In order to overcome the above problems, the existing public data "vehicle detector" (appearance patent application number: 201630633135.1) and "three-mode geomagnetic detection device" (utility model patent application number 202022457373.5) use a full transparent material to make the upper cover to improve the vehicle detection performance, while the existing two-mode geomagnetic product basically uses an opaque material for the upper cover, which is difficult to realize photoelectric signal collection, therefore, an optimal structure design scheme is needed to overcome and solve the problem.

After the signal pin 6 of the photoelectric sensor passes through the through hole 3 and is sealed with glue in the potting pool 2 for waterproofing, it can be used for internal photoelectric signal acquisition and integrated processing of vehicle detection.

[0015] The aforementioned photoelectric sensor 5 refers to an internal photoelectric effect device, a photovoltaic effect device, or a light intensity detection chip; the internal photoelectric effect device or photovoltaic effect device includes: a photoresistor, a photodiode, a phototransistor, or a photovoltaic cell; the light intensity detection chip detects and outputs the intensity of light through a photodiode or a phototransistor; preferably, in this embodiment, a photoresistor 5 is used for visible light data acquisition and comprehensive processing.

[0016] The bottom and surrounding area of ​​the aforementioned photoresistor 5 are waterproofed by a light-transmitting waterproof sealant; preferably, this embodiment uses a light-transmitting, high-temperature resistant, waterproof silicone sealant (hereinafter referred to as "sealing silicone").

[0017] The aforementioned light-transmitting lens 4 is a light-transmitting sheet or a condensing lens, and the materials include: quartz, glass, acrylic or PC plastic; since quartz sheets have inherent advantages in terms of high temperature resistance, purity, hardness and light transmittance, its hardness is second only to jade and diamond, reaching Mohs level 7, while the Mohs hardness of glass is only level 5-6, and it is easily scratched to reduce light transmittance.

[0018] Preferably, the quartz plate 4 is slightly lower than the outer surface of the shell and is sealed to the annular bottom surface of the recessed wide part above the photoresistor 5 with waterproof sealant. This reduces the risk of direct friction, impact, wear, and breakage from wheels and gravel to almost zero.

[0019] Based on the above-mentioned preferred options, the packaging process flow of this embodiment is detailed as follows:

[0020] First, apply the above-mentioned sealant silicone to... Figure 2 The bottom surface 90 of the narrow recess shown is then used to guide the two signal pins 6 of the photoresistor 5 through the through hole 3, allowing the photoresistor 5 to sit smoothly on the bottom surface 90 of the narrow recess. Figure 3 As shown;

[0021] Then, apply sealing silicone to photoresistor 5 again. Figure 2The quartz sheet 4 is embedded in the concave wide portion and stably seated on the annular bottom surface 91, and the quartz sheet 4 of the embodiment is tightly fitted with the inner wall of the concave wide portion, and a plastic hammer can be used to knock and tamp when seated, so that the sealing silica gel has better filling and sealing effect under extrusion;

[0022] Finally, as shown in Figure 4 the face shell is inverted, and the epoxy resin is injected into the glue pouring pool 2 to implement waterproof sealing for the signal pin 6 of the photosensitive resistor 5.

[0023] After the above treatment, the required excellent photoelectric signal can be collected in the multi-mode geomagnetic internal collection, so as to overcome the various problems of the two-mode geomagnetic and further improve the vehicle detection performance, Figure 5 for implementing the overall effect diagram of the multi-mode geomagnetic.
