] [Electronic fence, electronic fence quotes, electronic fence ALEPH ALEPH offered by electronic technology. Guangzhou Yi Li Fu Electronic Technology Co., Ltd. (www.alephchina.com) is located in the East Industrial Park Tong Guang Tong Road One, 3rd Floor, Guangzhou Tianhe District, Guangzhou City, 303, Contact: Chen Shengyou pulse electronic fence system consists of a high voltage pulse generating circuit, and alarm, master controller 3 major components. Typically, the electronic fence bare wire outside, along the existing fence installation. Traditional infrared radio alarm system may produce false positives, as long as there are people or things through, it will alarm occurs, therefore, not the newspaper also reported. The new pulse electronic fence system can distinguish between accidental touching and forcible invasion of the function, if someone accidentally touches a fence or other objects (such as tree branches) instant hit and the fence, because this is not a real invasion, the system does not have the ability to identify Call the police. Only when the intruder invasion force, the electronic fence to climb even malicious cut bare wire fence, causing the system break (open) or continuous touch line (short circuit), will be issued a warning. In order to prevent high-voltage electronic pulses bare wire fence on the interference of single-chip control system, taking into account measures to isolate the high-pressure, to avoid their entering into the main parts: First, between the main chip and the output port using optical coupling isolation , optical coupling isolation circuit so there is no direct connection between the two parts of the electrical circuit isolation is to prevent interference due to electrical connections caused. Second, the design of high-voltage pulse snubber circuit with varistors absorb the pressure, so that the high-voltage pulse can not enter the low voltage control section. The most important feature of the varistor is added on top of it when voltage is below its threshold "UN" when little current flowing through it, the equivalent of a shut valve, when the voltage exceeds the UN, flowing its current surge, the equivalent of the valve opens, varistors called electric shocks (surge) absorber, namely high-voltage pulse snubber circuit. In this design model is adopted 22Z2 varistors. All companies related products through the People's Republic of China Ministry of Public Security, all indicators were detected 100 percent qualified, China is home / business alarm machine, source of parts production enterprises. Intelligent electronic fence system, which combines defense, deterrence and alarm in one. As a new type of intelligent design, it can not only produce different grades of high pressure, can be free to switch between high and low according to security needs; to work independently and to be managed by a unified management center (for example a PC), control, pulse parallel operation of multiple hosts; and the use of optical isolation and other methods to reduce the high voltage pulse interference detection side host detection circuit, so that greatly reduce the false alarm rate, detection rate greatly increased, to ensure the system can be a long, continuous and stable operation. Intelligent electronic fence system hardware detection output by the electronic fence, change the input signal is determined by the software fence in the arm, contacts, short circuit and other working conditions, to achieve the status display, remote data communications, backup power automatic switching and charging management, live sound and light alarm. Our company has a number of years of experience in this industry, strong technology, high quality, enterprising team of professionals.
