Parking lock remote monitoring system based on LoRa

Abstract

A parking lock remote monitoring system based on LoRa comprises a power module, a parking lock main control board connected with the power module, a motor connected with the parking lock main controlboard, and a blocking mechanism connected with the motor. The power module can supply power to the parking lock main control board through a storage battery and a lithium battery. The parking lock main control board is used for receiving an unlocking instruction of a user and controlling the motor to work, thereby controlling the blocking mechanism to be automatically unlocked and locked and remotely reporting the inclination and vibration situation of the blocking mechanism. The parking lock main control board comprises an MCU, a limiting switch, an indicator lamp, a buzzer, an output module,a magnetic resistance sensor, a posture sensor, a Bluetooth module and a LoRa radio frequency module. Rapid and automatic unlocking can be realized, the posture sensor is added for monitoring the inclination and vibration situation of the blocking mechanism, an alarm signal is generated when the inclination and vibration situation exceed a preset threshold value, an alarm is remotely given through the LoRa radio frequency module, and the user can monitor the state of a parking lock remotely.

Description

technical field [0001] The invention relates to a remote monitoring system for a parking lock, in particular to a LoRa-based remote monitoring system for a parking lock. Background technique [0002] The parking lock is a mechanical device that prevents others from occupying one's own car parking space and allows one's car to stop at any time. Traditional mechanical parking locks rely on manual locking and unlocking, which is not very convenient and has been gradually replaced by remote control parking locks. Existing remote control parking locks generally include a parking lock body, a power supply embedded in the body, a communication module, and a parking lock control module. Judging the command and controlling the motor to automatically complete the unlocking / locking, and the power supply is used to supply power to the various components of the parking lock. [0003] The remote control parking lock in the above background technology generally adopts Bluetooth to establ...

AI Technical Summary

Problems solved by technology

Its defects are also obvious. Its effective range is related to transmission conditions, material coverage, antenna configuration and battery status. Most Bluetooth applications are designed for indoor environments. Signal fading due to wall attenuation and signal reflection will make the range far Less than the range specified by Bluetooth products

[0004] With the development of the city, parking spaces have gradually become a scarce resource. Many parking spaces in central communities, commercial and office buildings, etc. There are situations where parking locks are maliciously damaged, causing economic losses to car owners or parking lot managers

The existing remote control parking lock adopts bluetooth communication means, although it solves the problem of automatic unlocking at close range, it cannot solve the problems of free parking space query and remote alarm
