Embodiment
below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
embodiment.The intelligent safety detection instrument of information outer net, as shown in Figure 1: comprise power supply 6, power supply 6 is connected with Main Processor Unit 1 by drive circuit 7, Main Processor Unit 1 is connected with the Ethernet interface 3 for link information outer net 2; Described Main Processor Unit 1 is connected with warning circuit 5 by D/A converter 4; Described warning circuit 5 is connected and is connected with power supply 6; Described Main Processor Unit 1 is also connected with RS232 interface 8 and GE port 9.
described warning circuit 5 as shown in Figure 2, comprises the first not gate IC1 that input is connected with power supply 6, and the output of the first not gate IC1 is connected with the input of the second not gate IC2, and the output of the second not gate IC2 is connected with the positive pole of LED; Also comprise one end and be connected to power supply 6, the other end connects the buzzer SP of the collector electrode of NPN type triode Q, and the grounded emitter of described NPN type triode Q, base stage is connected to the negative pole of described LED; Also be provided with trigger switch K1 between described power supply 6 and the first not gate IC1, the control end of trigger switch K1 is connected with PWM chip 5.Be provided with the first resistance R1 between described trigger switch K1 and the first not gate IC1, be connected by the second resistance R2 between the input of the first not gate IC1 and the output of the second not gate IC2.The input of described first not gate IC1 is by the first electric capacity C1 ground connection; The input of described first not gate IC1 is also by the 3rd resistance R3 that is cascaded and disengage button K2 ground connection.The first NAND gate IC4, the 3rd not gate IC3 and the 4th resistance R4 is also in series with between described second not gate IC2 and LED; Wherein one of them input of the first NAND gate IC4 is connected with the output of the second not gate IC2, another input is connected with the output of the first NAND gate IC4 with the 6th resistance R6 by the 5th resistance R5 be cascaded, the output of the first NAND gate IC4 is connected with the input of the 3rd not gate IC3, and the output of the 3rd not gate IC3 is connected with the positive pole of LED by the 4th resistance R4; The output of described 3rd not gate IC3 is also connected to by the second electric capacity C2 on the connected node of the 5th resistance R5 and the 6th resistance R6.
the NAND gate that not gate wherein used can use two inputs to be communicated with, as shown in Figure 2.
operation principle of the present utility model: Main Processor Unit is by Ethernet interface obtaining information from information outer net, to detect the safety problem such as wed leak and web page horse hanging of outer net, when detect there is safety problem time, Main Processor Unit can send the digital signal of triggering to the trigger switch of warning circuit, this digital signal is converted to analog signal (high level), to trigger trigger switch through D/A converter.
after trigger switch K1 is triggered, the input of the first not gate IC1 is high level, and through the second not gate IC2 output is high level, now LED electrified light emitting, and the base stage high level of NPN type triode Q, buzzer SP is switched on work, gives the alarm; Owing to being connected by the second resistance R2 between the input of the first not gate IC1 and the output of the second not gate IC2, achieve level self-locking, therefore disappear in the triggering signal of trigger switch, still can export high level with the output of the second not gate IC2, LED and buzzer are worked on.When contact button K2 presses, the second not gate IC2 output low level, the first NAND gate IC4 exports high level, the 3rd not gate IC3 output low level, alarm stop alarm, and the warning standby condition entering next round.
first resistance R1 and the first electric capacity C1 constitutes warning trigger-delay circuit.When trigger switch K1 obtains a high level, this voltage is charged to the first electric capacity C1 by the first resistance R1, and the voltage on the first electric capacity C1 can raise gradually, and causes the first not gate and the upset of the second not gate.If the high level lasting time that trigger switch K1 circuit obtains is too small, then the undertension of the input of the first not gate is to reach the degree causing the first not gate upset, and alarm also would not be reported to the police.When arranging, the resistance of the second resistance R2 is for should be far longer than the first resistance R1, like this, no matter is triggering signal or ring off signal, and the voltage that the second resistance R2 transmits all can not produce the impact of essence on them.But after triggering signal or ring off signal disappear, the second resistance R2 plays a role, and self-locking voltage is sent to the input of the first not gate.Changed the time length of trigger delay by the value changing the first resistance R1 and the first electric capacity C1, their value is smaller, and the sensitivity of triggering is just higher; Their value is larger, more blunt to the reaction triggered.
