Description
本創作係屬於物聯網網路設備的領域，特別是關於一種應用於長距離低功耗物聯網網路技術的移動式定位裝置，作為車輛在移動中的定位用途，以協助警察單位緊急查緝涉案車輛的需求者。 This creation belongs to the field of IoT network equipment, especially a mobile positioning device applied to long-distance low-power IoT network technology, as a positioning purpose of the vehicle in motion, to assist the police unit to urgently investigate the case. The demand of the vehicle.
按，由於「低功耗廣域網路(Low Power Wide Area Network，以下簡稱為LPWAN)」技術具有低頻寬、低功耗、遠距離、低資料量等特性，是智慧城市發展物聯網不可或缺的重要通訊技術，其能夠同時滿足包括環境監控、街道照明、停管系統、智慧建築、智能監控錶及車隊管理等全方位應用需求，與傳統的大數據網路相同。 According to the "Low Power Wide Area Network (LPWAN)" technology, it has the characteristics of low frequency, low power consumption, long distance, low data volume, etc., which is indispensable for the development of the Internet of Things in smart cities. The important communication technology can meet the needs of all-round applications including environmental monitoring, street lighting, stop system, smart building, intelligent monitoring table and fleet management, just like the traditional big data network.
而，低功耗廣域網路仍是使用無線網路做為底層機制，且為了因應物聯網裝置省電、長距離傳輸資料的需求才應運而生，由於LPWAN不要求複雜的影音、大資料傳輸、即時訊息等，而提供各種物聯網產業持續前進的動力，加上LPWAN相關技術難度不高，所以許多低功耗長距離的技術陸續被提出，較受注目的包括使用授權頻段的NB-IoT(Narrow Band-IoT)，以及採用非授權頻段的LoRaWAN、Sigfox、Weightless、HaLow、RPMA(Random Phase Multiple Access)等。 However, the low-power WAN still uses the wireless network as the underlying mechanism, and it has emerged in response to the demand for power-saving and long-distance data transmission of the IoT device. Since LPWAN does not require complex audio and video, large data transmission, Instant messaging, etc., while providing various IoT industries to continue to move forward, coupled with LPWAN related technology is not difficult, so many low-power long-distance technologies have been proposed, more attention including the use of licensed band NB-IoT (Narrow Band-IoT), and LoRaWAN, Sigfox, Weightless, HaLow, and RPMA (Random Phase Multiple Access) using unlicensed bands.
基於物聯網的運作機制，其所蒐集到的資料(又稱之為大數據)仍必須經過閘道器(Gateway)、網路伺服器(Network Serve)進行傳輸，才 能在後端進行資料分析，由於大數據是分析數據中相當重要的資產，因此，擁有大數據就變的相當重要，目前Sigfox屬於私有網路，資料進行回傳後都會由Sigfox掌握；而LoRaWAN為公開網路，可讓個別使用者用有這些大數據的擁有權，因此，當某些資料可能涉及商業機密或保密問題時，多數使用者仍希望使用LoRaWAN。然而，在LoRaWAN的機制中，下行資料都是全面性地廣播至全數的Gateway，所以每個Gateway都必須同時處理上行與下行傳輸，當傳輸的負載過重時則會導致全面性壅塞而使網路癱瘓之現象，對於使用者來說是相當不樂見的問題。 Based on the operation mechanism of the Internet of Things, the data collected (also known as big data) must still be transmitted through Gateway or Network Server. Data analysis can be performed on the back end. Since big data is a very important asset in analyzing data, it is very important to have big data. At present, Sigfox belongs to the private network, and the data will be mastered by Sigfox after the backhaul; and LoRaWAN For the public network, individual users can have ownership of these big data, so when some information may involve trade secrets or confidentiality issues, most users still want to use LoRaWAN. However, in the LoRaWAN mechanism, the downlink data is broadcast to all Gateways comprehensively, so each gateway must handle both uplink and downlink transmissions. When the transmission load is too heavy, it will lead to comprehensive congestion and network. The phenomenon of sputum is quite unpleasant for the user.
有鑑於此，本創作人遂因應警察單位有緊急查緝涉案車輛之需求，利用物聯網應用中低功率長距離的LoRaWAN傳輸窄頻技術，搭配使用本創作之移動式定位裝置的定位機制，以將黑名單車牌由黑名單管理系統一推播至每一個與該移動式定位裝置電性連接的警車、警用機車或是攝影機上，以快速定位涉案車輛的位置，並透過該每一移動式定位裝置將資料上傳，使下行資料與上行資料的傳輸不同步，藉以降低資料傳輸時的負載，解決網路可能癱瘓而影響資料傳輸的問題。 In view of this, the creator used the low-power long-distance LoRaWAN transmission narrow-band technology in the Internet of Things application in response to the needs of the police unit to urgently investigate the vehicle involved in the case, and used the positioning mechanism of the mobile positioning device of the present invention. The blacklist license plate is pushed by the blacklist management system to each police car, police locomotive or camera that is electrically connected to the mobile positioning device to quickly locate the location of the vehicle involved and through each mobile positioning. The device uploads the data, so that the downlink data and the uplink data are not synchronized, so as to reduce the load when the data is transmitted, and solve the problem that the network may be paralyzed and affect the data transmission.
