With the promotion of the concept of low-carbon travel in recent years, the use of high-end bicycles, electric vehicles, and motorcycles has increased, and the subsequent stolen and difficult-to-track vehicles have become a major problem that plagues many car owners. However, the common vehicle anti-theft solutions on the market still have many defects[1]:

(1) 2G otinga: Ko te 2G kei te whakaheke i te kaha me te whakamutu mai i te whatunga, me te ngoikore o te kapinga, te tohu tohu kore, kaore he tohu i nga waahi waka i raro, me te kaha o te kai.

(2) Rongoā RFID: Ko te waka neke atu i te tekau mita te mamao mai i te pou o te kaipānui RFID, he ngoikore rawa te tohu, kaore e taea te korero i nga korero, ka motuhia te taunga; kaore e kitea te motuka, ka aru ranei i te mataeinaa, i te tuawhenua ranei, a ko te rohe taone ka whaaiti noa ki nga whakawhitinga matua; Me tirotirohia nga kaipānui pou rori me te tiaki i nga wa katoa.

Ko te whainga ki nga ngoikoretanga o nga kaupapa e rua i runga ake nei, ko tenei pepa e hoahoa ana i te punaha anti-tahae waka mohio i runga i te NB-IOT, he painga ki te whanui whanui, hononga nui, me te iti o te hiko.

1 Hanganga hoahoanga

The intelligent anti-theft system based on NB-IOT mainly includes three parts: equipment terminal , background processing system and user terminal. The system terminal sensor can be connected to the operator’s IO domain intranet through NB-IOT. The background application system supports the docking of public security network interactive case data. The user can monitor the vehicle through the mobile phone, and the background management system can maintain the overall user data. Management and monitoring.

2 Mahere katoa

This system transfers the GPS&Beidou satellite dual-mode positioning data and the state value of the vibration sensor to the single-chip STM32, which is then uploaded to the core network through the NB-IOT communication module, and transmitted to the cloud platform through the HTTPS protocol, and then through the cloud transparent transmission function, It is forwarded to the cloud server, then stored to MySQL and transmitted to the APP on the mobile phone.

3 Hoahoa taputapu taputapu

Ko nga taputapu taputapu o tenei punaha kei te nuinga o te waa ko te tohu tohu tuuturu waka, GPS & Beidou amiorangi kowiri-aratau waeine me te korero korero NB-IOT, STM32 kotahi-maramaraiti microcomputer mana kōwae. Ko te anga o te punaha taputapu e whakaatuhia ana i te Whakaahua 2. Ko te mahinga o te waahanga kitenga wiriwiri ko te kimi i te ahua o te motuka me te mea he nekehanga ano o te waka. Ko te mahi a te GPS & Beidou amiorangi whakatuunga-aratau rua ko te kimi i te turanga o te waka, te tiki i te ahopae me te ahopou uara, ka tuku atu ki te STM32-maramara kotahi. NB

The function of the IOT communication module is to send the vehicle status collected by the sensors and the positioning information resolved by the main control chip to the IoT cloud platform. As the main control chip, the STM32 microcontroller is the core part of the system hardware. Its function is to implement the underlying functions of the system through code, such as obtaining the longitude and latitude data of the GPS& Beidou satellite dual-mode positioning through the serial port interrupt and detecting whether the vibration sensor inputs a high level , Pack the acquired data and upload it to the cloud server through the NB-IOT module. At the same time, it also receives the instructions issued by the mobile phone APP to determine whether the anti-theft mode should be turned on.

3.3 Te wetewete i nga hua whakamatautau

Ka kitea mai i te Whakaahua 2 kei roto i nga waahanga rereke hyperparameter Agent1 ~ 4, ko te rere o te waka i nga waahanga Agent1, Ag ent2, me Agent3 kei te whakahaerehia i te 600 veh / h, i te wa e rere ana te waka i te waahanga Agent4 ka whakahaerehia i te 500- 600 veh / h. Tenei whakaturanga Ka taea e ia te kii taurangi te rereketanga me te tupurangi o nga mahinga whakamatautau. I waenga i a raatau, ko te mana tohu i roto i te hononga hokohoko kaihoko ma te roanga o te raarangi tatari i te whakawhitinga; ko te mahi ki te whakanui i te uara utu kua kohia, ka taea te whakaatu ma te tino uara o te rereketanga i waenga i te rarangi tatari ki te rawhiti-mauru me te raki-tonga. Ko nga hua o te whakamatau e whakaatu ana, kua whakaritea ki te uara mahi whatunga neural o Agent1 me Agent2, Ag

Ko te mahinga o ent3 me Agent4 i roto i te whakahaere tohu tohu taone nui atu te pumau, me te tere toharite o te Agent4 he nui ake me te roa o te raarangi tatari tatari he iti ake, he pai ake i te Agent1, Agent2, me Agent3.

Whakapuakanga

I runga i te punaha SCATS, e whakaaro ana to taatau whenua he hohonu te whakapakari algorithm ako mo te kaihoko waka (Agent) i runga i te hononga whakawhiti tohu tohu uaua o te taone ki te kohikohi, whakatauira me te wetewete i nga rerenga rerenga waka i nga waa rereke, tae atu ki te waahi o nga waka taone. , Te tere tere o te ao, te roa o te raarangi tatari tatari me etahi atu whaihanga raraunga, ko nga hua o nga tohu tohu taone nui kua riro he pumau ake. Na roto i te maaramatanga o nga waahanga rerekee rereke me te kowhiringa o nga kaupapa taurangi reta matomato, ka tutuki i nga hiahia tohu tohu o te whakawhitinga whakawhiti i nga waa rereke.
