冒險筆記

在自動控制領域， PLC技術和PC-based技術是當前比較具有代表性的控制技術， 兩者的技術起源和發展有較大的差異。 PLC(Programmable Logic Controller)產生於上世紀70年代初。 最早的PLC是以替換繼電器系統的角色出現， 其主要實現的功能僅僅是邏輯簡單的順序控制功能。 PLC一經出現， 就以其高可靠性、小體積和直觀的程式設計模式而顯示出強大的生命力， 成為自動控制領域的“明星”。  PC-based是一種基於PC技術的控制系統。 最早的PC-based控制系統是以工控機為核心， 通過擴展帶PCI介面的專用板卡組成。 PC-based借助於IT技術的發展，在運算、存儲、 組網和軟體開放性方面具有優勢。 PLC和PC-based兩者在技術特點上存在明顯區別。 PLC具有體積小、功耗低、抗幹擾能力強； 具有很高的可靠性，其平均無故障率時間間隔（MTBF）可達50萬、 甚至100萬個小時；具有簡單直觀的程式設計模式(如梯形圖)； 具有內部即時時鐘。 而PC-based具有大運算能力； 具有開放標準的系統平臺和PCI介面；精美且低成本的顯示技術； 豐富的組網能力。 但系統的可靠性略差， 如性能較好的IPC的平均無故障時間間隔約5萬小時。 此外，PC-based雖然具有很強的CPU， 但其多工作業系統是非即時的， 所以程式的迴圈週期反而沒有高性能的PLC快。 PLC更適合於設備控制，而PC-based更多地用於設備運行狀態的監視。 相對於PC-based而言，PLC具有配置靈活、體積小、適應惡劣環境、 抗幹擾性強、可靠性高等優點 ，但在軟體功能及系統開放性等方面比PC-based稍差。 當然，隨著電腦技術和控制技術的不斷發展， PLC和PC-based都在吸收對方的優點，以適應更多的應用現場。 例如，PLC在包裝設備中的應用遠遠多於PC-based在包裝設備中的應用。 隨著PC-BASED的工業電腦 （簡稱工業PC，與普通的電腦相比，它具有防塵、防振、抗電磁、耐高低溫等優點） 的發展，以工業PC、I/O及監控裝置、 控制網路組成的PC-BASED的自動化系統逐漸成為工業自動化的另一種實現方式。 PC-BASED自動化系統源於PC， 可完全融入到網路時代的資訊系統中， 具有高性能、低價格、系統開放、豐富的人才和應用基礎等優勢。

Challenges It is a standard need for retail stores to prevent shrinkage. For large, spacious retail stores such as Great Lakes Outdoor Supply, it is hard to have enough human resources to patrol every corner in store. Additionally, due to the sales of firearms, it requires tighter attention to the sales floor area to document any activities and protect customers, employees. To achieve minimized blind spots for loss prevention and better incident awareness for improved customer service, video surveillance is needed to monitor any possibility o...

Gulf Gas Stations Accord Security Standard with QNAP Security Surveillance Solution Background Gulf Georgia is one of the leading oil companies on the Georgian market, and it provides high quality fuel and customer services. Gulf Georgia currently successfully operates 140 refueling stations throughout the nation, 43 of which are located in Tbilisi, the capital of Georgia. Gulf gas stations are distinguished with modern equipment and state-of-art innovative technologies. Challenges According to the ministry of internal affairs of Georgia, it requires that the gas stations deploy surveillance devices to detect the vehicle ID of each vehicle that enters the gas station. The quality of the vehicle ID image should be at least 10 Megapixels for easy identification. To meet this security standard set by the government, Gulf Georgia started to test various IP cameras capable of capturing videos with required resolution. After the qualified IP cameras were chosen, Gulf Georgia fell into the st...

Japanese Police Station Enhances Staff Security with QNAP Security Surveillance Solution Background Japanese police station plays an important role in maintaining the security of the responsible districts. The core duty of the police officers is to regularly patrol around the beat to prevent crime and misdemeanor and so to safeguard people. Other duties include first aid service, emergency response, traffic directing, etc. Challenges While the police officers protect people, the police officers themselves, likewise, need protection too. When they are on duty, countless people come and go around the buildings. Besides, important documents that are stored inside the police stations need to be kept safe. Most important of all, for the police officers who take the night shifts, they need proper measures to protect their safety when not many colleagues stay in the station to take care of one another. To enhance the total security of the police station, the need of a well-rounded surveillanc...

Tbilisi Metro Uses QNAP Security's NVR Solution to Safeguard the Underground City Background Tbilisi Metro, operated since December 1966, is a rapid transit metro system in Tbilisi, the capital of Georgia. At present, the system consists of 2 lines with 22 stations. Constructed at the depth of 100 meters underground, Tbilisi Metro is one of the deepest subways in the world. Many people in the city depend heavily on Tbilisi Metro for daily traveling because of its convenience. Challenges From the perspective of surveillance system deployment, the environment of Tbilisi Metro is quite complicated. As the metro is built underground 100 meters deep, it requires advanced deployment that could support strong network connection. Hence, optical fiber is used for any network appliance in the metro system to fulfill the demands of high-speed intranet connection. On the other hand, being one of the busiest public transportations, Tbilisi Metro is always crowded with people, and the need for a...

Georgia government adopts QNAP Security's solution for medical shops area monitoring throughout the country Background Georgia is a sovereign state in the Caucasus region of Eurasia. To prevent crime and create a safer living environment for its people, Georgia government requires in the national law that all the drugstores deploy a surveillance system to avoid possible crimes from illegal drug trading or dealing. Challenges Based on the law and security policy, each drugstore has to deploy three to four 3-Megapixel IP cameras around the store. The cameras are set at the corner of the store in order to gain comprehensive monitoring of the status inside and the surrounding environment. Besides, the recorded videos need to be kept for one month long. As a result, a surveillance system that could provide sufficient bandwidth for video streaming simultaneously from four IP cameras and large storage capacity for long-term video recording appears to be important in the project. Solution ...
