Detailed Description

The principle of the pulse electronic fence security system is as follows: the pulse output end of the energy control system outputs a high-voltage low-energy pulse voltage signal which is applied to the starting end of the electronic fence through the high-voltage insulated wire, the pulse voltage signal is transmitted to the terminal end from the starting end along the energy transmission device of the electronic fence, and then the pulse voltage signal is applied to the pulse input end of the energy control system through the high-voltage insulated wire, so that the pulse electronic fence with the high voltage blocks an intruder outside the perimeter. Although the pulse voltage is very high (the voltage peak value is more than or equal to 5000V), the acting time is very short (the current duration is less than or equal to 0.1 s), and the released energy is very small, so that the injury to a person touching the fence can not be caused, and only the person touching the fence can feel the limb sensation due to the touching of the high voltage.

The utility model discloses a high-voltage pulse replaces lasting high-voltage electricity on the traditional rail, and high-voltage pulse is produced and is propagated on the rail by high-voltage electronic pulser to prevent people or animal to cross the rail. The safety device comprises a monitoring center (PC), a high-voltage electronic pulser and an electronic fence, as shown in figure 1. The high-voltage electronic pulser takes an STM32ARM as a main control chip and comprises BOOST boosting, automatic amplitude limiting, flyback boosting conversion, pulse control, fence state detection and the like. The high-voltage pulse is output by adopting four levels of 5000V/6000V/7000V/8000V according to the requirement, and the user can adjust and set freely according to the precaution requirement. Meanwhile, the high-voltage electronic pulser can be numbered, a plurality of defense areas are arranged, the high-voltage electronic pulser is communicated with a monitoring center in a wireless transmission mode, and unified management control and setting are carried out by a PC (personal computer) of the monitoring center. The LCD display with a dot matrix is configured, so that the current time, the working voltage, the environmental temperature, the fence state, the alarm information, the communication state and the like can be displayed, and the use and the maintenance are convenient.

The monitoring center (PC) realizes the initial configuration and centralized management of the high-voltage electronic pulser; the front-end electronic fence forms a precaution perimeter, the core of the device is a high-voltage electronic pulser which generates high-voltage pulse signals, detects signals fed back by the electronic fence, analyzes and judges the states of the front-end detection fence, such as defense arrangement, net touching, short circuit, open circuit and the like, sends the signals to a monitoring center through wireless communication, and realizes on-site alarm.

The device adopts external 24V direct current or alternating current power supply and is provided with a 12V direct current storage battery as a standby power supply. The functions of charging, switching and the like of the storage battery are realized. When the external power supply fails or is powered off, the power supply can realize automatic switching, and the 12V standby storage battery supplies power to the system, so that the continuity and stability of the working state of the system can be ensured. The device can carry out three stages of quick charge, complementary charge and floating charge on a 12V storage battery, and the service life of the storage battery is ensured. When the voltage of the storage battery is lower than 9V, an impulse type quick charging method is adopted, after the quick charging is finished, the electric quantity of the battery is not necessarily sufficient, in order to ensure that the battery is charged with 100% of electric quantity, complementary charging is carried out, constant voltage charging is adopted in the stage, the capacity of the battery can be quickly recovered, at the moment, the charging current is gradually reduced, and when the current is reduced to a certain threshold value, the floating charging stage is shifted to trickle charging. This stage is mainly used to compensate the energy consumed by the self-discharge of the battery, so that the battery is always in a sufficient state of charge.

The device takes a direct-current working voltage of 12V as an initial power supply of a BOOST circuit, and can BOOST the voltage to 125V/150V/175V/200V according to the requirement by selecting different amplitude limiting detections through BOOST; then, flyback boost conversion is performed to obtain 5000V/6000V/7000V/8000V pulse voltage required by people, as shown in fig. 2, the switching tube Q1 is periodically turned on or off under the action of charging pulse, so that the inductor L1 stores energy and releases energy, the energy stored in the inductor L1 is stored in the energy storage capacitor C2 through the diode D1, and the output voltage (P point voltage) at two ends of the diode D1 is determined by the amount of transmitted energy. The voltage at the point P gradually rises under the action of the energy storage inductor. Any one of the four paths of signals enters the comparator through the analog switch, and then the four paths of signals are compared with a preset and fixed voltage threshold value of the comparator. When the voltage does not reach the set value, the output is high level, and the Q1 is triggered by the AND gate and the charging pulse signal phase, namely the charging pulse signal, so that the conduction and the disconnection of the Q1 are controlled, and the continuous charging of the C2 is realized. Once the sampling voltage reaches the threshold value, the comparator outputs low level, Q1 keeps a cut-off state, energy is not transferred, the voltage of a point P is kept constant, and the function of automatic amplitude limiting is realized. The ARM controls the on-off of the Q2 through a discharge pulse, the on-off of the primary side of the transformer is controlled through the flyback isolation boosting transformer T1, the corresponding 5000V/6000V/7000V/8000V pulse voltage can be obtained on the secondary side of the transformer, and the 5000V/6000V/7000V/8000V pulse voltage can be transmitted to the electronic fence to serve as a high-voltage working pulse. When the switching tube Q2 is turned off from on, an induced voltage is generated on the primary side of the transformer. After the induced voltage is superimposed with the input voltage, this energy will be injected into Q2, creating a high voltage spike at the drain of Q2. If the electrical spike is above the acceptable voltage of Q2, it is easily damaged. For this purpose, a clamping protection circuit consisting of D2 and D3 is added to clamp or absorb the spike voltage. The clamping protection circuit has the advantages of small energy loss, extremely high response speed and capability of bearing transient high-energy pulses.

The HIGH-voltage working pulse generated by the HIGH-voltage electronic pulser is transmitted to the detection circuit and the electronic fence, whether illegal invasion occurs is judged by detecting the state of the fence in real time, the circuit for detecting the state of the fence is shown in figure 3, COM is regarded as a reference level, namely regarded as a zero potential line, HIGH is a positive voltage, and LOW is a negative voltage. L1, L2, L3 and L4 are connected with a pull-up resistor through an optical coupler and input to the ARM. Points L1 and L3 respectively detect the state before positive and negative voltages are output to the fence, and points L2 and L4 respectively detect the state after the positive and negative voltages pass through the fence and return. The working state of the fence is judged by detecting the signals. In order to prevent interference, an optical coupler is adopted to realize isolation of an I/O channel so as to improve the intrusion detection rate and reduce the false alarm rate. The optocoupler implements an "electro-optic-to-electrical" conversion such that the ARM and peripheral circuitry are completely isolated from electrical contact by the optocoupler. After photoelectric conversion, the ARM judges a switching value signal input to a port, and when the optical coupler is conducted, points L1, L2, L3 and L4 are low levels; conversely, L1, L2, L3, L4 points are high. The ARM judges the working state of the fence through different high and low level combinations among the four signals L1, L2, L3 and L4, namely fence protection, net touch, short circuit and open circuit. When the illegal invasion of the fence is detected, the on-site alarm is sent out, and meanwhile, the alarm information is transmitted to a PC of the supervision center.

Because install the fence additional above four defence areas enclosure in the garden, set up a plurality of video monitoring device around the fence again simultaneously, consequently, it is very important with timely, accurate transmission of multiunit field data to the surveillance center. The invention adopts the traditional ZigBee module and GPRS module to realize data communication, and is shown in figure 4. In order to save cost, data processing in each defense area is realized by an ARM (main control chip optional: STM32F 407) in a high-voltage electronic pulser, collected field data and node addresses are processed by the ARM and then are sent to a ZigBee module (main chip optional LRF 215A) and uploaded to a monitoring center, the monitoring center can send information functions to mobile phone terminals of workers through a GPRS module, meanwhile, data are uploaded to a server through a GPRS wireless module, and the monitoring center feeds back control instructions according to the uploaded data information. The wireless transmission module of the device adopts a chip SIM800A as a transmission module of a chip core, the module is a two-frequency GSM/GPRS module, the working frequency of the module is 900/1800MHz, the functions of low-power voice, short message and data transmission and the like can be realized, and the control can be realized by transmitting a standard AT command through a serial port.

The working process of wireless transmission is as follows: data transmission to ARM of on-the-spot collection, ARM converts analog signal into digital signal through 12 bit ADC, obtains all effective values of gathering data, packs detection node sequence number and effective value and transmits for the zigBee module through the serial ports, and the zigBee module is through Z-Stack protocol Stack with data transmission. The ARM obtains data of each on-site acquisition node through a serial port and sends an AT instruction to control the GPRS module, and the GPRS module finally sends terminal data to the monitoring center and the mobile phone terminal.

ARM sends AT instruction and needs to initialize central processing module for zigBee module and GPRS module, establishes the network connection with the zigBee module of detecting node module through the zigBee module, establishes the TCP connection with the monitoring center through the GPRS module, when establishing the connection, need to pass through "handshake many times" just can establish the connection. And after the ZigBee module receives the data, the data are packaged and transmitted to the monitoring center through the GPRS module. When the uploaded data are identified as dangerous signals, early warning signals are issued through the GPRS module, and early warning short messages are sent to the mobile phone terminal.

The high-voltage working pulse generated by the high-voltage electronic pulser is adopted, so that high voltages of different grades can be generated, and the high voltage and the low voltage can be freely switched according to security requirements; the pulse host can work independently, and can also be managed and controlled uniformly by a management center (such as a PC), so that the parallel operation of a plurality of pulse hosts is realized; meanwhile, the method of photoelectric isolation and the like is adopted, so that the interference of high-voltage pulses to a detection host and a detection circuit is reduced, the false alarm rate is greatly reduced, the detection rate is greatly improved, and the long-time, continuous and stable operation of the system is ensured; in addition, the ZigBee module and the GPRS module are adopted to realize data communication and can send data to the mobile phone terminal, so that the diversity of communication is increased, the emergency response capability is submitted, and the security system of the park is further ensured and improved.
