Embodiment
It is BLE with each wireless communication apparatus, and using main BLE- for the networking mode of BLE.
Hand handle module is located in the hand handle of perambulator, realizes the function of carrying out detection, environment measuring and system human-computer interaction.
There is: BLE (master) to establish connection as between Master (holotype) and other modules, carry out data transmission in hand handle module；It connects
Nearly sensor carries out detection for detecting whether someone holds handle；Temperature/humidity sensor, it is warm and humid for detecting environment
Degree；Air quality sensor, for detecting ambient air quality；Key/LED light, for realizing the control to each module of perambulator
System and status display, i.e. system human-computer interaction.
Main control module is located between two rear-wheels of perambulator, for realizing cart slope detection, abnormal motion detection, hand
Machine APP interaction, music, the functions such as intelligent braking.Have on main control module: BLE (from), as Slave (slave pattern) and hand
Module is attached, is carried out data transmission；Bimodulus bluetooth module receives the control letter of mobile phone for being attached with mobile phone
Number and audio data.Audio-frequency module (not shown) handles the audio data received and plays out audio；
Velocity sensor, for detecting the implementation speed of perambulator；Six axle sensors, for whether detecting cart currently in slope
And whether there is abnormal motion；Brake gear, according to hand handle module detect whether someone hold hand handle information and six
Axle sensor testing result decides whether to execute brake, if unmanned hold handle of stopping, and cart is on slope or has different
Normal movement carries out brake, otherwise cancels brake, this is intelligent braking function.
Front-wheel control module is located between two front-wheels of perambulator, for realizing warning lamp and headlamp control and
Front-wheel intelligent positioning.There is: BLE (from) to be attached in front-wheel control module as Slave and hand handle module, carries out data biography
It is defeated；Safety lamp is installed at cart front-wheel, and safety lamp is opened when night carries out can be improved safety；Front wheel orientation device is used
In realize front-wheel orientation and it is universal between switch, realize intelligent positioning function.Warn lamp switch and front-wheel oriented control switch
Both it is in handle module, is transmitted by the key in operating handle module, then by BLE (from), may be implemented
On and off.
As shown in figure 4, the figure shows the networking pairing steps of stroller system.
In general, need to carry out networking pairing between the hand handle module of a perambulator, main control module, front-wheel control module,
Otherwise two perambulators (A, B) nearby when, be easy to produce the case where hand handle module similar to A is connected to the main control module of B.
Pairing carries out when leaving the factory, is not necessarily to user's operation, matches process are as follows:
Step1: being triggered on main control module by button, and BLE (master) initiates pairing request, broadcasts pairing request letter outward
Breath.
Step2: BLE (from) scanning in hand handle module is to the BLE (master) for requesting pairing, according to the wide of BLE (master)
It broadcasts information and identifies as BLE (master), and its MAC Address and mark are stored in flash, so as to subsequent connection.
(wherein, the MAC Address of BLE is unique, can be used as unpaired message and is saved, so as to the identification of subsequent connection.)
Step3: the BLE (from) in hand handle module sends pairing check information and gives BLE (master), and BLE (master) saves BLE (from)
MAC Address into flash, so as to subsequent connection.
Step4: being triggered in front-wheel control module by button, and BLE (from) initiates pairing request, repeats step1~3.Such as
Fruit repeats the above steps there are also other modules, completes pairing networking.
After the completion of pairing, normal connection can be established between a perambulator modules, and is protected in the flash of each BLE
The incongruent equipment of the unpaired message deposited will be rejected connection.
The function of information transmission mode and realization inside the perambulator in networking:
BLE (master) in hand handle module is Master by the application, and the BLE in other modules is used as from Slave, Suo Youcong
Star Network is connected and composed between master.Main and between information transmission can be carried out directly, and information is transmitted between Cong Yucong
It is to be transmitted to by BLE (from) BLE (master), then another BLE (from) is transmitted to by BLE (master).Based on this point, the letter of stroller
Breath transmission is as follows:
Intelligent braking: when holding handle, handle module is detected, BLE (master) sends result to the BLE of main control module
(from) executes un-brake；When hand leaves handle, handle module will test the BLE that result is sent to main control module by BLE (master)
(from), hereafter main control module is according to six shaft detections as a result, judging whether cart is in slope or has abnormal motion, if there is then
Brake is executed, and brake implementing result is returned into BLE (master).
Safety lamp and intelligent positioning: it by the function key control on handle, will be controlled before information is transferred to by BLE (master)
Take turns the BLE (from) of control module.
Intelligent braking switch: by the pattern switching key control on handle, master is transferred to for information is controlled by BLE (master)
The BLE (from) in module is controlled, realizes the switch of intelligent braking.After intelligent braking is closed, traditional service brake can be used.
System switching machine:
When current system is in open state, long-pressing power key, hand handle sends shutdown command by BLE (master) and gives master control mould
The BLE (from) on BLE (from) and front-wheel control module on block, is shut down, hereafter main control module and front-wheel control module
There is BLE to be partially in broadcast state (every 500ms is actually taken to broadcast outward once) at a slow speed, so that the power consumption of the two is extremely low, hereafter
BLE connection disconnects, the shutdown of hand handle module.When current system is in off-mode, power key in long-pressing hand handle module, hand handle mould
Block booting, this rear-handle BLE (master) start to scan, as the BLE (from) of scanning to the main control module and BLE of front-wheel control module
When (from), connection is established therewith respectively, hereafter main control module and the booting of front-wheel control module, system boot are completed.
Have a BT module on main control module, which is a bluetooth bimodulus module, include audio bluetooth and BLE,
Sound intermediate frequency bluetooth receives the audio-frequency information that mobile phone transmits, and play for connecting with mobile phone.BLE can be carried out with mobile phone
Connection, for receiving the control signal of mobile phone, returning to cart information can be by cart network by the connection of mobile phone to mobile phone
It is connected to internet.Information transmitting between mobile phone and the network is as follows:
Safety lamp and intelligent positioning: being controlled by cell phone application, and mobile phone connects cart by BT module, and control information is passed
It is defeated by main control module, main control module is transferred to the BLE (master) in hand handle module, hand handle module for information is controlled by BLE (from)
The BLE (from) in front-wheel control module is forwarded the information to again.
Intelligent braking switch: being controlled by cell phone application, and mobile phone connects cart by BT module, and control information is transferred to
Main control module realizes the switch of intelligent braking.
Cart status display and networking save: being controlled by cell phone application, mobile phone connects cart by BT module, all to push away
Car data, including temperature and humidity, air quality, implementation mileage, real-time cart speed etc. can be by the network transmissions to master control
Module is finally shown by the BT module transfer on main control module to mobile phone, and is passed to cloud by phone network and done data
Statistics and analysis.
