Specific embodiment
A specific embodiment of the invention is made further detailed below against attached drawing by the description to optimum embodiment
Thin explanation.
NB-IoT (Narrow Band Internet of Things, NB-IoT) is the emerging technology in one, the field IoT,
Low power consuming devices are supported to connect in the cellular data of wide area network, also referred to as low-power consumption wide area network (LPWAN).NB-IoT support to
Machine time length, the efficient connection to network connectivity requirements higher device.
NB-IoT has four characteristics: first is that wide covering, it will thus provide improved in-door covering, under same frequency range, and NB-
IoT is equivalent to than existing network gain 20dB and improves the ability of 100 times of overlay areas；Second is that having support magnanimity connection
Ability, mono- sector NB-IoT can support 100,000 connections, support low latency sensitivity, ultralow equipment cost, low set
The network architecture of standby power consumption and optimization；Third is that more low-power consumption, the stand-by time of NB-IoT terminal module is 10 years；Fourth is that more
Low module cost, single successive module expected from enterprise are no more than 5 dollars.
The application be exactly realized using NB-IoT communication unit feature it is a kind of based on NB-IoT communication module intelligently
Lock system, the system include the ground latch mechanism, microprocessor, NB-IoT communication module by the lifting of motor control, micro process
Device realizes that microprocessor receives external control signal, microprocessor and electricity by NB-IoT communication module using 51 single-chip microcontrollers
Machine is connected for controlling rotating and reverse for motor, and microprocessor is controlled according to the external signal that NB-IoT communication module receives
Motor processed rotates and reverse, to lock with rising corresponding parking stall, at this time vehicle to control the rise and decline of ground latch mechanism
It can not be parked in parking stall.
There are two types of transfer modes for external signal, a kind of to be issued using mobile phone, another acquisition car-mounted terminal.When using mobile phone
When, mobile phone connects the base station NB-IoT by mobile network, is then connect by the base station NB-IoT with NB-IoT communication module, by mobile phone
Control signal be transmitted to microprocessor.Here base station is equivalent to NB-IoT relaying, is used for forward signal.The motor of mobile phone input
Control signal is transferred to microprocessor by NB-IoT, by rotating and reverse come match control letter for microprocessor control motor
Number.
When using car-mounted terminal, car-mounted terminal includes vehicle-mounted NB-IoT communication module, vehicle-mounted NB-IoT communication module with
Car body controller connection, car body controller are connect with vehicle-carrying display screen or push button.By push button, vehicle-carrying display screen come
Input ground lock unlocking signal, then sends a signal to microprocessor by vehicle-mounted NB-IoT communication module by car body controller,
By the positive and negative rotation of microprocessor control motor.When vehicle is close to parking stall, pass through the unlock touch-control of touch screen or setting onboard
After button is pressed, unlocking control signal is transferred in microprocessor by NB-IoT communication mode, electricity is controlled by microprocessor
Machine turns anyway.
Microprocessor is connect with vehicle detection module, and vehicle detection module is for detecting at parking stall with the presence or absence of vehicle.Inspection
Whether measuring car is parked at parking stall, after vehicle leaves parking stall, after microprocessor detects signal by vehicle detection module, and control
Motor rotation processed, so that motor drives ground latch mechanism to rise, thus parking stall of locking.Vehicle detection module can use various ways
It detects, including earth magnetism wagon detector or ring coil detector, microwave detector, ultra sonic vehicle detector.With earth magnetism
For wagon detector, due to vehicle in parking stall and not under the two states of parking stall, the Geomagnetic signal at parking stall is different, root
Judge vehicle whether in parking stall according to this signal.The normally-closed contact K3 of relay KM3, relay are concatenated between power supply and motor
The coil of device KM3 is by microprocessor driven power on/off.When by having vehicle on geomagnetism detecting parking stall, false triggering is made in order to prevent
At berth lock malfunction, at this time microprocessor control relay coil be powered, at this time normally-closed contact K3 disconnect, that is, electricity
Source can not power to motor, can not manipulate motor positive and inverse at this time, that is, after avoiding vehicle from being parked on parking stall, due to not opening
It accidentally touches out and locks rise with causing come the accident for the vehicle that scratches.After vehicle is outputed, microprocessor can stop drive KM3 after
Electric appliance is powered, and normally-closed contact connects motor power supply again, can control berth lock locking by mobile phone, vehicle-mounted touch screen at this time.
Configure geomagnetism detecting, it is ensured that ground lock will not malfunction, and scratch vehicle body.
As for the positive and negative rotation of motor, one of implementation be by rotate forward relay KM1, reversion relay KM2 come
It realizes, it is corresponding to generate main story and reversion since wiring is different, the difference of U, V, W three-phase electricity of input for three-phase electricity
Two states can be realized at this time by relay, after power supply output is drawn along normally-closed contact K3, respectively according to line
Difference, which is divided into, rotates forward circuit, reversion circuit, and concatenation setting main story relay KM1 is respectively corresponded in rotating forward circuit and reversion circuit
Normally opened contact K1, reversion relay KM2 normally opened contact K2, then the coil of KM1, KM2 are by microprocessor driven power on/off.To
Circuit intervention motor or reversion circuit intervention motor are rotated forward to control, to realize the positive and negative rotation of motor.
In the application, the circuit integrations such as NB-IoT communication module, microprocessor, relay form a control on control panel
Unit processed, is microprocessor, the power supply of NB-IoT communication module by power supply, and the output end of microprocessor is separately connected relay
The coil of KM1, the coil of KM2, KM3 coil, for driving the energization of relay coil；NB-IoT communication module is to be based on
The core of NB-IoT Internet of Things mechanics of communication intelligently locked, the reception and upload of user data.
The workflow intelligently locked based on NB-IoT Internet of Things mechanics of communication is as follows, and user passes through cell phone application or behaviour
Decline is locked as button control instruction with issuing, after NB-IoT communication module receives the digital quantity signal of platform, by single-chip microcontroller
After handling digital quantity signal, the analog signals of DC12V+ will be issued to the control coil of relay, relay control coil band
Electricity is so as to cause contact closure, to realize that major loop is closed, motor is rotated forward or inverted in final realization ground lock.Electromagnetism simultaneously
Detection identifies vehicle location by earth's magnetic field magnetic flux change, and when vehicle leaves parking stall, control motor rises automatically, completes whole
A workflow.When vehicle is on parking stall, the normally-closed contact of relay KM3 is disconnected, and avoids locking caused by maloperation
Accidentally rising is made vehicle and is accidentally scratched to vehicle.
Obviously present invention specific implementation is not subject to the restrictions described above, as long as using method concept and skill of the invention
The improvement for the various unsubstantialities that art scheme carries out, it is within the scope of the present invention.
