Detailed description of the invention
Fig. 1 is the structural schematic diagram of one of the utility model embodiment parking lot detector.
Specific embodiment
For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with attached drawing
The utility model is described in detail with embodiment.
Referring to Fig. 1, a kind of structural schematic diagram of parking lot detector for the utility model embodiment.Parking stall detection
Device 10 is embedded among parking stall, for measuring the earth magnetism field data of the parking stall to identify whether there is vehicle on parking stall, and data is passed through
Wireless mode uploads.Specifically, which includes: controller 11, communication module 12, power management module 13, electricity
Source module 14, geomagnetic sensor 15 and maintenance module 16.
The input terminal of the power management module 13 connects power module 14, and output end is separately connected controller 11 and communication mould
Block 12, for providing power supply.
The controller 11 carries out pin with communication module 12, geomagnetic sensor 15 and maintenance module 16 respectively and is electrically connected.
Specifically, controller 11 is micro-control unit, by CPU, RAM of computer, ROM, timer conter and a variety of I/O sets of interfaces
At the computer on one chip, forming chip-scale, different combination control is done for different applications.
The geomagnetic sensor 15 is used to detect the changes of magnetic field of parking stall, and when judging that parking space state changes, to
Controller 11 sends corresponding trigger signal.
Specifically, which judges changes of magnetic field information according to pre-set Geomagnetic signal fluctuation threshold
Whether it is greater than fluctuation threshold, and trigger signal is initiated according to judging result, and be transmitted to controller 11.Wherein, judging result packet
Include following situations:
When changes of magnetic field information is greater than fluctuation threshold, it is determined that current parking space state is to have vehicle；
When changes of magnetic field information is less than fluctuation threshold, it is determined that current parking space state is no vehicle；
When being less than fluctuation threshold when big when changes of magnetic field information, determine that current parking space state is abnormality, and send
Warning information is to controller 11.
Further, which is spaced detection changes of magnetic field to schedule, in the present embodiment, should
15 every five seconds of geomagnetic sensor detects Primary field variation, and exports corresponding trigger signal.
Controller 11 receives parking space information, realizes the detection to parking space state, and the operating mode of the controller 11 includes stopping
Dormancy standby mode and normal operation mode；Low-power consumption standby mode is in when controller 11 is flat, when geomagnetic sensor 15 detects
Current parking space state is to generate corresponding wake up trigger signal when having vehicle, enters normal operation mode, control with active controller 11
The starting of power management module 13 processed is to enable power module 14 to be that communication module 12 provides working power, and earth magnetism is sensed
The testing result that device 15 carries out parking stall measure is uploaded by communication module 12.Then, which enters back into the standby mould of suspend mode
Formula, at this point, it is that communication module 12 provides working power that power management module 13, which is closed to stop power module 14,.
In the present embodiment, which is waken up by the interrupt pin of geomagnetic sensor 15, and controller 11 exists
By geomagnetism detecting device 15 interrupt pin wake up when in a dormant state, the dormant state be identified as controller 11 control turn down or
Person closes the output of a part of voltage, so that premise is not influence the case where controller restarts work into battery saving mode
The lower output for closing a part of voltage.
In the present embodiment, which is wireless communication module, further, is based on 2.4Ghz/433Mhz/
The communication module of NB-iot wireless communication technique.
The maintenance module 16 is connect with the output end of power management module 13, is also connect with controller 11.
Further, when communication module 12 is in running order, it is also used to receive the calibrating installation of a parking lot detector
The sleep signal of transmission, and be sent to controller 11, controller 11 respond the sleep signal, start maintenance module 16 and enter to
Machine dormant state.
Power module 14 is adjusted to communication module 12 for controlling power management module 13 after the maintenance module 16 starting
Power supply makes communication module 12 enter battery saving mode, with the proviso that being that do not influence communication module 12 communicates with calibrating installation foundation
The output of a part of voltage is closed in the case where connection.
When the communication module 12 in battery saving mode receives the wake-up signal that calibrating installation is sent, the wake-up signal is sent
To controller 11, so that controller 11 is responded the wake-up signal and open operating mode, receive the data that geomagnetic sensor 15 is sent.Into
One step, control maintenance module 16 enters suspend mode standby mode after which opens operating mode.
Therefore, it is completed when parking lot detector produces, it, can be in calibrating installation by the maintenance module 16 of setting before storage
Control under allow parking lot detector to enter sleep state.After parking lot detector is installed, then pass through calibrating installation wirelessly activating.
To solve the problems, such as power consumption of the parking lot detector during inventory, extend the service life；And the site environment of different parking stalls is different,
It can also be by wirelessly calibrating parking lot detector, to adapt to current environment before product comes into operation and in use process.
Further, when parking lot detector 10 enters operating mode, which is also used in communication module 12
When the data of biography do not receive base station reply, next data transmitting period is switched to next communication channel and sends data.When
It receives and stays in this channel when base station is replied and wait for that next data transmitting period continues to send data, when not receiving base station
Next communication channel is switched in next data transmitting period when reply and sends data, is to the last returned to after a channel
First channel continues to send data.
Therefore, which automatically selects work according to the radio link of working environment by automatic frequency adjustment
Channel, the environmental disturbances being likely to be encountered when to avoid parking lot detector and base station communication.
Parking lot detector 10 in the utility model embodiment has following technical characterstic:
(1) it is communicated between parking lot detector and base station using 2.4G/433Mhz, it is automatic to change when signal is interfered
Frequency channels are communicated；
(2) 160 seconds parking space states can be stored, the parking stall detection data of primary transmittable 160 seconds of communication；
(3) low battery or other anomalous events be can record, and uploaded automatically, administrative staff and maintenance personnel is allowed to obtain in time
Know；
(4) have waterproof, resistance to compression, shock resistance, weight, high temperature, the high and cold lower normal work of road environment；
(5) after parking space detector installation, upper surface is leveled with the original ground, and does not influence to pass through, and does not influence snow sweeper operation, no
It is beautiful to influence road；
(6) long-time ponding will not damage equipment, and equipment can recover immediately work after releasing ponding；
(7) portable prover can be matched, a key calibration is carried out to parking stall detector within the scope of 1 meter, is visited without concern parking stall
Survey device number；
(8) heavy-duty battery and intelligent power saving algorithm are used, it can be continuous work 5 years or more.
