Description

Technical Field

[0001] The utility model relates to the technical field of smart parking lots, and in particular to a signal acquisition module of a parking system. Background Art

[0002] In existing parking systems, signal acquisition of gates usually relies on fixed hardware connections and traditional signal transmission methods. This traditional signal acquisition method has many shortcomings. First, due to the fixed hardware connection, once the position of the gate changes or needs to be repaired or replaced, the entire system needs to be tediously disassembled and rewired, which brings great inconvenience to system maintenance and upgrades. Secondly, the traditional signal transmission method is limited by the length of the cable and signal attenuation, resulting in a limited signal transmission distance, and is easily affected by external electromagnetic interference, resulting in unstable signals or even loss. In addition, existing parking systems usually lack real-time monitoring and feedback mechanisms for the status of gates, and are unable to promptly detect and handle abnormal conditions in the operation of gates, bringing potential safety hazards to the normal operation of parking lots.

[0003] The parking system in the prior art usually lacks a real-time monitoring and feedback mechanism for the gate status, and is unable to promptly detect and handle abnormal conditions in the gate operation, which is not conducive to practical use. Utility Model Content

Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0023] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings. Specific embodiment one:

[0025] Reference Figure 1-6 A signal acquisition module for a parking system includes a collector housing 1 and a circuit board body 4.

A first end cover 2 and a second end cover 3 are respectively arranged at both ends of the collector housing 1, and the first end cover 2 and the second end cover 3 are both screwed to the surface of the collector housing 1. One end of the circuit board body 4 is engaged with the surface of the first end cover 2. An electrical component 5 is arranged on the surface of the circuit board body 4. The entire device places the circuit board body 4 through the collector housing 1, and protects both ends through the first end cover 2 and the second end cover 3 to prevent falling off, while protecting the circuit board body 4, making it easy to operate the circuit board body 4 and realize access to an external parking system.

[0026] To facilitate the installation and connection of the entire device, positioning ears 9 are provided on both sides of the bottom surface of the collector housing 1, and the positioning ears 9 and the collector housing 1 are integrated by injection molding. The entire device can be connected to the external device through the positioning ears 9 on the surface of the collector housing 1 to achieve the installation of the entire device. Guide grooves 6 are provided on both sides of the inner wall of the collector housing 1, and the guide grooves 6 are blind grooves. The inner walls of the guide grooves 6 are clearance-matched with the side of the surface of the circuit board body 4. The circuit board body 4 and the collector housing 1 are detachably installed using the guide grooves 6, which is convenient for replacing the circuit board body 4 or disassembling and repairing the electrical components 5 on the surface. A connection interface 7 is provided at one end of the circuit board body 4, and an interface card slot 8 is provided on the surface of the first end cover 2. The interface card slot 8 is clearance-matched with the connection interface 7, which is convenient for exposing the connection interface 7 on the surface of the circuit board body 4 to achieve access to external devices through lines.

[0027] Other limiting structures of the entire device are that the surface cross-sectional size of the first end cover 2 is the same as the surface cross-sectional size of the second end cover 3, and the thickness of the first end cover 2 is the same as the thickness of the second end cover 3; the edges of the collector housing 1, the first end cover 2 and the second end cover 3 are all rounded to the same size to facilitate the processing and molding of the entire device; the electrical component 5 is connected to the surface of the circuit board body 4 by screws, and the electrical component 5 is electrically connected to the circuit board body 4. Specific embodiment 2:

[0029] Reference Figure 1-6 In actual use, the entire device is connected to the camera of the external parking system for use, mainly for information collection. The recognition camera of the parking system provides a 485 communication expansion interface. The collector enters the parking system through the 485 communication connection. The parking system needs to read the signal of a certain gate and sends a read command to the 485 interface of the camera of a certain gate. The microcontroller on the circuit board obtains the command by monitoring the 485 interface and returns the status of all the signals on site. Since the internal circuits of the receiver and sender of many signals on site are different and cannot be directly connected, a relay isolation measure is added through the electrical component 5, so that the system can operate normally. Specific embodiment three:

[0031] Reference Figure 1-6 The system control logic of the entire collector is to detect the data of the external gate's anti-smashing meter-wave radar, the gate's dry position switch, and the gate's drop-bar position switch, and transmit them to the gate's signal acquisition board through hard wiring, and transmit them to the gate's intelligent recognition camera through 4G / 5G communication, and transmit them to the parking system's background software through LAN communication to complete the access of the device of this application connected to the parking system.

[0032] In summary:

[0033] The collector housing 1 is slidably connected to the circuit board body 4 for use, and enters the parking system through the circuit board body 4 through the 485 communication connection. When the parking system needs to read the signal of a certain gate, it sends a read command to the 485 interface of the camera of a certain gate. The single-chip microcomputer on the circuit board body 4 obtains the command by monitoring the 485 interface, and returns the status of all signals on site, and isolates them through the electrical component 5. By connecting with the parking system, the anti-smashing radar signal of the gate, the gate rod lifting signal, and the gate rod falling signal are collected, which is convenient for operators to better operate the parking system.
