Abstract

The utility model relates to an automatic alarming perimeter high-voltage power grid, which comprises a host computer, a slave computer, a power supply and a power grid, and is characterized in that the host computer and the slave computer are entirely controlled by a single chip microcomputer, and an RS-485 bus is used for data communication between the host computer and the slave computer. The host computer sends an intelligent predicted or preset alarming trigger threshold value to each salve computer in turn, and each salve computer receives the instruction and outputs the power frequency sine high-voltage electricity of single cycle by a current limiting high voltage transformer, meanwhile detects the voltage and electric quantity of the power grid. If the alarming trigger threshold value exceeds the trigger thresh value, the utility model immediately outputs the sustained high voltage current to strike. The utility model is widely applied in the special occasions of the prison, detention house, factory, airport, and armament and ammunition depots etc. The utility model has the advantages of small electricity consumption in usual detection, sufficient striking strength, strong environmental adaptability, non easy occurrence of the wrong alarming, good performance of expansibility and reduction of manufacturing cost of the whole system etc.

Description

Circumference high-voltage fence control device

Technical field: the utility model relates to a kind of warning device, relates in particular to a kind of circumference high-voltage fence capable of automatic alarm.

Prior art: in social life, to important unit of country and facility reinforcement security work is extremely important, as: particular places such as prison, detention house, factory, airport, ordnance ammunition depot, in numerous security devices, electrical network is because it is easy for installation, control range is wide, advantage such as cheap is still adopted by a lot of units.At present, known circumference high-voltage fence device all is to adopt instrument transformer to be inverted the control mode or the employing capacitor discharge generation action of low-voltage pulse of current limliting, and boosting by high voltage pulse transformer becomes the working method of high-voltage pulse electricity again.Though these control modes can realize certain function, exist power consumption big, the power utilization rate is low, the environment self-adaption poor performance, and function expansibility can be poor, be not easy to the miscellaneous equipment interface, and the project cost height easily produces problems such as false alarm.

Technology contents: for the deficiency of the control that overcomes existing circumference high-voltage fence device, meet " GA247-2000 prison institute circumference high-voltage fence device " standard simultaneously again, the utility model has adopted a kind of advanced person's control mode, has solved above contradiction effectively, has reached excellent performance.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of circumference high-voltage fence control device capable of automatic alarm comprises main frame, power supply, regional power grid, several extension sets and high-tension transformer, it is characterized in that: the high voltage control box in described main frame and several extension sets all adopts single-chip microcomputer to control, and links to each other by two lines of power supply and RS-485 between the two; Described high-tension transformer is arranged on the high voltage control box in the described extension set, and links to each other with corresponding regional power grid; Described regional power grid is provided with the high pressure checkout gear, and described high pressure checkout gear links to each other with described high voltage control box.Its effect is: control mode adopts by main frame and sends in turn by intelligent predicting or predefined warning triggering threshold values to each extension set, after each extension set receives separately instruction, high-tension transformer by current limliting is exported the sinusoidal high-tension electricity of power frequency in single cycle, detection of grid voltage and electric weight simultaneously to electrical network; Trigger threshold values if surpass, then export the high-tension current that continues immediately, till the strike electric weight of output meets predetermined standard; Do not trigger threshold values if surpass, then extension set only sends data such as real-time voltage, electric weight to main frame, continues the detecting of next round simultaneously; Main frame is analyzed after receiving real-time data immediately, notes abnormalities and carries out the type of sound and light alarm indicating positions and abnormal conditions.

The utility model compared with prior art has following advantage:

1. meet " GA247-2000 prison institute circumference high-voltage fence device " standard comprehensively;

2. the voltage that can show electrical network in real time by main frame, data such as electric weight; Power consumption is very little when detecting at ordinary times, and intensity is enough when hitting;

3. report to the police and trigger threshold values by the main frame intelligent predicting, environmental suitability is strong;

4. utilize the multiple check of single-chip microcomputer to guarantee that control device is stable, be difficult for producing false alarm;

5. because the data communication of the standard of employing makes scalability good, reduce the cost of whole system.

6. owing to only hit electric current in the course of work, therefore have little power consumption, characteristics that efficient is high to unusual subregion output high pressure occurring.

Embodiment: as can be seen from Figure 1, a kind of circumference high-voltage fence control device capable of automatic alarm comprises main frame, power supply, regional power grid, several extension sets and high-tension transformer, it is characterized in that: the high voltage control box in described main frame and several extension sets all adopts single-chip microcomputer to control, and links to each other by two lines of power supply and RS-485 between the two; Described high-tension transformer is arranged on the high voltage control box in the described extension set, and links to each other with corresponding regional power grid; Described regional power grid is provided with the high pressure checkout gear, and described high pressure checkout gear links to each other with described high voltage control box.Connection line between main frame and the extension set is simple, connects many again extension sets and also has only these two kinds of leads to connect, and has so both saved cost, has reduced operating expenses, and out of order probability is reduced.

As can be seen from Figure 2; main frame provides power supply through power supply control with after protecting for motherboard provides operating voltage and each extension set by the AC power of 220V, and the alarm signal that power supply control simultaneously and sound square circuit reception motherboard send is added to loudspeaker after treatment and reports to the police.Motherboard control output RS-485 signal and each extension set carry out communication; Motherboard is responsible for processing and the demonstration of panel and the demonstration in zone of keyboard signal simultaneously, thereby realize the processing of line voltage, electric weight, warning etc.

As can be seen from Figure 3, the high voltage control box receives the control signal that main frame sends, by single-chip microcomputer signal is handled, exported the sinusoidal high-tension electricity detection signal of power frequency in single cycle by the high-tension transformer of constant current to electrical network, simultaneously by high-voltage detecting circuit detection of grid voltage and electric weight; Trigger threshold values if surpass, then export the high-tension current that continues immediately, till the strike electric weight of output meets predetermined " GA247-2000 prison institute circumference high-voltage fence device " standard; Do not trigger threshold values if surpass, then extension set only sends data such as real-time voltage, electric weight to main frame, continues the detecting of next round simultaneously.
