Non-contact acoustic monitoring and LoRa transmission system and method based on stereo garage

Abstract

The invention discloses a non-contact acoustic monitoring and LoRa transmission system based on a stereo garage, and the system comprises the stereo garage, four wireless sensor nodes are installed on each lifting platform of the intelligent stereo garage, a sound sensor is used for collecting sound signals after an automobile enters the garage, and data transmission is carried out through LoRa. The four wireless sensor nodes transmit collected sound to the upper computer, the upper computer judges the position and state of an automobile engine by using a sound source localization method, and the invention further discloses a non-contact acoustic monitoring and LoRa transmission method based on the stereo garage. New wires and network cables are not needed, and installation is convenient and flexible. An existing intelligent stereo garage only needs to be directly installed on the lifting platform, and rewiring is not needed. According to the transmission method, a LoRa self-organizing clustering network is adopted, a plurality of entrances and exits can be remotely monitored, and operators on duty at the entrances and exits are reduced.

Description

technical field [0001] The invention relates to a non-contact acoustic monitoring and LoRa transmission system and method based on a three-dimensional garage, in particular to a safety detection device combining acoustic monitoring, LoRa transmission and a piezoelectric vibration energy collection device, belonging to the technical field of safety detection. Background technique [0002] With the rapid development of my country's economy, the number of cars is increasing every year. Facing the sharp contradiction formed by the rapid growth of vehicles and limited parking spaces, intelligent three-dimensional garages emerged as a new type of parking lot. [0003] At present, the safety detection of the intelligent three-dimensional garage mainly uses a photoelectric switch, which can only detect the size of the car through the on-off situation of the photoelectric switch, but cannot detect the running status of the engine after the car enters the garage. Once the three-dimen...

Problems solved by technology

[0003] At present, the safety detection of the intelligent three-dimensional garage mainly uses photoelectric switches, which can only detect the size of the car through the on-off status of the photoelectric switch, but cannot detect the running status of the engine after the car enters the garage.

Once the three-dimensional garage is stored in an idling car, accidents are likely to occur, ranging from vehicle damage to damage to garage equipment, causing unnecessary losses
