Embodiment approach 1
[0025] In the first embodiment, the detection module is composed of two parts, one part recognizes the vehicle information through the license plate recognition system installed at the entrance of the three-dimensional parking garage, and the other part detects the vehicle information through the sensor system installed on the vehicle board. The vacancy of the parking space; wherein the license plate recognition system is responsible for identifying the license plate information of the vehicle entering the warehouse, and uploading the license plate information to the user interaction module;
[0026] The sensing system is composed of a geomagnetic sensor, an ultrasonic sensor, a micro control unit module, an NB-IoT communication module, and a gateway. The geomagnetic sensor and the ultrasonic sensor transmit the detected data to the micro control unit module, wherein the geomagnetic The sensor is used to measure the magnetic field strength of the parking space. When a vehicle e...
Embodiment approach 2
[0043] This embodiment should be understood as including all the technical means of all the aforementioned embodiments, and further, in the second embodiment, the motion module is composed of a lifting transmission mechanism and a lateral movement mechanism. In this embodiment, the three-dimensional The garage adopts a lifting and traversing three-dimensional garage, wherein the lifting transmission mechanism is composed of a reducer 1, a motor 1, a normally closed brake with a braking torque not less than 1.5 times the rated load, and a hydraulic system. It consists of a reducer 2, a motor 2, a driving wheel, a brake, a guide rail, and a driven wheel; the lifting transmission mechanism and the lateral movement mechanism are each controlled by a frequency converter, and the frequency converter is responsible for receiving the The motion command, and send the final motion result to the storage control module, wherein the frequency converter includes: frequency converter 1 contro...
Embodiment approach 4
[0054] This implementation mode should be understood as including all the technical means of all the above-mentioned implementation modes, and further, in the fourth implementation mode, the terminal controller of the user interaction module adopts a radio frequency card identification system in this embodiment, and the The core system of the user interaction module is controlled by a PLC master controller; wherein the radio frequency card identification system realizes the self-service card swiping function to pick up the car, and the terminal display screen of the user interaction module displays the specific position of each vehicle and the situation of all parking spaces in real time, The driver can store the car into the warehouse through the radio frequency card. After the driver swipes the card, the signal is sent to the PLC master controller to control the car-carrying board to move the car-carrying board to the ground floor through the preset data path, and wait for the...
