Remote-control intelligent floor lock having parking place state detecting function

Abstract

The invention discloses a remote-control intelligent floor lock having a parking place state detecting function.According to the remote-control intelligent floor lock, a Bluetooth communication module is adopted for receiving an external operation instruction, remote control of the floor lock can be completed through a mobile phone with Bluetooth and other mobile equipment, special remote control equipment is not needed, control is easy and convenient, a good encryption effect is achieved, and power consumption is low; terrestrial magnetism intensity data in two axis directions around the floor lock is collected, the floor lock is automatically controlled to be closed according to changes of the terrestrial magnetism intensity data around the floor lock, and control accuracy is good.After it is judged that a vehicle parks on a parking place, the intelligent floor lock is remotely controlled to enter an intermittent working mode, so that the power consumption of a system is effectively lowered; a non-vehicle environment value is automatically updated, it is avoided that when a fixed non-vehicle environment value is adopted, components work for a long time or the external environment changes, so that zero drift is judged by mistake, and meanwhile because correcting and updating are performed according to the previous non-vehicle environment value, occasionality is avoided.

Description

Technical field [0001] The present invention relates to the field of wireless communication technology and vehicle detection technology, in particular to a remote intelligent lock with a parking position detection function. Background technique [0002] The related technical background of the present invention is described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] As intelligent life is more and more needed by people, intelligent and humanized parking space locks have emerged. The most common ground lock is a mechanical manual ground lock. This type of ground lock requires the user to get off the vehicle for operation during use, which is very inconvenient. In recent years, some remote control parking spaces have appeared. Remote control parking lot locks can be roughly divided into the following three categories. The first category is the ground lock based on the remote control solution of NORDIC's nRF24 series ...

AI Technical Summary

Problems solved by technology

The advantage of the second type of parking lock is that the network covers a large area and can be applied to mobile devices such as mobile phones equipped with WiFi. However, the overall system of this type of parking lock consumes a lot of energy and the chip cost is high.

The advantage of the third type of ground lock is that it is directly connected to the wide area network, and can realize connection and remote control anytime and anywhere. However, its energy consumption is extremely high, and the cost of communication chips and modules is extremely high. In the subsequent use process, it is necessary to continue to pay the network to the mobile operator. Traffic fees, so not very practical

Moreover, among the ground locks in the prior art, no ground lock has a parking space detection function, and the lock cannot be automatically closed when the car leaves the parking space, and the user needs to operate. to scratch

At the same time, in terms of parking space detection technology, existing detection methods, such as ultrasonic and infrared, have their own limitations, are easily affected by the environment, and the cost of camera image recognition is extremely high.

These have led to the application of geomagnetic detection technology more and more widely. However, in the existing geomagnetic detection methods, the accuracy is still not high, and the detection work needs to be done all the time. It is easy to cause zero drift due to the influence of the internal or ambient temperature of the device, and whether it works is not subject to the user's flexibility. Control and other issues
