Description

Network video transmission equipment

Technical Field

The utility model relates to an theftproof and video transmission equipment technical field, especially a network video transmission equipment.

Background

Along with the higher living standard of people, the corresponding anti-theft of areas such as families and the like is more and more important. The detection heads adopted by the anti-theft equipment applied to the family at present mainly comprise various microwave and infrared detection heads installed in the family, door magnetic detection heads installed on the inner sides of doors and windows and the like. The alarm based on the detection head has a commonality, namely, the alarm is carried out only after a thief enters a room (the door magnetic probe alarm can only carry out the alarm after a door and a window are opened), so that a user cannot be informed at the first time when an alarm condition occurs, and if the thief enters the room to rapidly take a case and escape, the thief cannot be informed to a related department at the first time to catch the thief due to the delay of the alarm time.

At present, in an alarm based on video monitoring, a camera is used for shooting a monitoring area (such as a home) for a long time during working, then the camera transmits continuously shot video data to a far end through a GPRS module and a wireless mobile network, and a user can master the conditions in the home in real time after the far end passes through field video data displayed by a mobile phone or a PC. The above mode has a problem that a user needs to watch the display screen to know the field situation, when people are at work or do other things, the user cannot watch the video data displayed by the mobile phone or the PC in real time, generally, the user watches the display screen at certain time intervals, so that when a thief steals a time period, but the user cannot know the conditions of home and the like when the user does not look up the displayed video at the moment, and the loss is brought to the user. In addition, especially when the operating current of the GPRS module is large (generally about 160 mA), the continuous operation of the GPRS module not only causes electric energy waste, but also consumes electric energy in a relatively short time if the whole device is powered by a storage battery, so that the whole device cannot operate normally, and frequent charging in a relatively short time also causes inconvenience to a user. Based on the above, the network video transmission device which can generate an alarm signal before a thief intends to enter a home or other areas to steal, can stop working when relevant devices such as the GPRS module and the like are not in an alarm condition, saves electric energy, and can prompt a user to watch a display screen of a mobile phone or a PC at the first time when the relevant devices are in the alarm condition is provided.

Fig. 1 and 2 show, the utility model discloses before the use, switch SK is opened to the user, the power of battery G output gets into closely detection circuit (standby current is only about 50 mu A) and remote detection circuit (standby current is only about 50 mu A), vibration detection circuit (standby current is only about 10 mu A), the power input both ends of control circuit (standby current is only about 5 mA), then closely detection circuit and remote detection circuit, vibration detection circuit, control circuit are in the operating condition that gets electric. This novel GPRS module A5, SMS module A6, camera A4 etc. are in the power-off state when not stealing the condition at ordinary times, save the electric energy as far as possible. This novel remote detection circuit and short-range detection circuit's infrared detection switch installs in the door outside of family moderate, can survey the personnel through the family gate.

As shown in fig. 1 and 2, in the remote detection circuit: when a person passes through or stays outside the door far distance of 150cm, the 3 feet of the infrared detection switch A3 do not output high level outside the detection range of the detection head of the infrared detection switch A3, a subsequent control circuit cannot be powered on to work, and the short message module, the camera and the GPRS module cannot be powered on to work.

When a person stays in a place far away from a doorway within 150cm, within a detection range of a detection head of an infrared detection switch A3, 3 feet of an infrared detection switch A3 output high level, the high level is subjected to voltage reduction and current limitation through an adjustable resistor RP1 to charge an electrolytic capacitor C1, after 30 seconds, when the electrolytic capacitor C1 is fully charged, the high level output by the 3 feet of the infrared detection switch A3 is subjected to voltage reduction and current limitation through a resistor R2, the base voltage entering an NPN triode Q1 is higher than 0.7V, then, the NPN triode Q1 conducts a collector output low level, the low level is conducted in a unidirectional mode through a diode 73VD 23 to enter a photodiode hidden in an optical coupler A2 of a control circuit, and then the control circuit is electrified to work, and the short message module, the camera and the GPRS module are all electrified to work. In the novel remote detection circuit, a person is far away from a door of a house, which means that the person is not a thief, the person passing by or the person stays outside the door temporarily and is not dangerous, so that the power supply of the control circuit is not switched on within a certain time, and the power supply of the control circuit is switched on only when the possibility that the thief waits for theft is high after a long time; and on the premise of preventing unnecessary false alarm signal pushing, the anti-theft device can also play a good anti-theft role.

As shown in fig. 1 and 2, in the proximity detection circuit: when someone passes through or stays outside the door with a distance of 60cm, the 3 feet of the infrared detection switch A1 do not output high level outside the detection range of the detection head of the infrared detection switch A1, the subsequent control circuit cannot be powered on to work, and the short message module, the camera and the GPRS module cannot be powered on to work. When a person stays within 60cm close to a door (a thief may open a door), within the detection range of a detection head of the infrared detection switch A1, 3 feet of the infrared detection switch A1 can output high level, the high level is subjected to voltage reduction and current limitation through the adjustable resistor RP to charge the electrolytic capacitor C, the high level output by the 3 feet of the infrared detection switch A1 is subjected to voltage reduction and current limitation through the resistor R within 8 seconds (the time is adjustable, the charging time of the electrolytic capacitor C is prolonged after the resistance value of the adjustable resistor RP is adjusted to be large, the delay time is prolonged, and otherwise, the delay time is shortened) when the electrolytic capacitor C is not fully charged, the base voltage of the NPN triode Q is lower than 0.7V, the NPN triode Q is cut off, a subsequent control circuit cannot be powered to work, and the short message module, the camera and the GPRS module cannot be powered to work. When a person stays in a door 60cm, within the detection distance of a detection head of the infrared detection switch A1, 3 feet of the infrared detection switch A1 output high level, the high level is subjected to voltage reduction and current limitation by the adjustable resistor RP to charge the electrolytic capacitor C, after 8 seconds (the time can be shortened), when the electrolytic capacitor C is fully charged, the high level output by the 3 feet of the infrared detection switch A1 is subjected to voltage reduction and current limitation by the resistor R, the voltage of a base electrode entering the NPN triode Q is higher than 0.7V, then the NPN triode Q is conducted, a collector electrode outputs low level, the low level is conducted in a one-way mode by the diode VD1 to enter a photodiode hidden in an optical coupler A2 of the control circuit, and then the control circuit is powered to work, and the short message module, the camera and the GPRS module are. Among this novel short-range detection circuit, the gate of being at is nearer apart from someone (output power behind 8 seconds, because the thief can not open the door in the very short time, probably other personnel temporarily pass through the gate), means probably that the thief will prize door etc. and get into indoorly, consequently switch on the control circuit power in the time of relative section, prevented that can not in time propelling movement alarm signal, can play good theftproof effect.

Fig. 1, 2 show, among the vibration detection circuit, this novel use, mercury switch SQ's mercury liquid level is located the circuit board lower extreme perpendicularly (and is located mercury switch SQ's glass housing inner lower extreme), and normal push-and-pull, switch door can not lead to two contacts on upper portion in mercury liquid level contact mercury switch SQ, and silicon controlled rectifier VS is switched on by can being triggered so, and follow-up control circuit can not be the electric work, and SMS module and camera, GPRS module all can not be the electric work. When the door is violently damaged by a thief to generate large vibration in use, after the mercury liquid level is vibrated, the mercury liquid level can contact two contacts at the upper part in the mercury switch SQ, and then the positive electrode of a 12V power supply can be subjected to voltage reduction and current limitation through the mercury switch SQ with the contacts closed instantly to trigger the conduction of the silicon controlled rectifier VS through the resistor R3, so that the high level output by the cathode of the silicon controlled rectifier VS is subjected to voltage reduction and current limitation through the resistor R4 and enters the base electrode of an NPN triode Q2, the NPN triode Q2 is conducted, the low level output by the collector of the NPN triode Q2 is subjected to unidirectional conduction through the diode VD3 and enters the cathode of a built-in photoelectric diode of an optical coupler A2 of the control circuit. This is novel at someone violence destruction door (including destroying the initial stage that is located the outer infrared detection switch of door and shell body, camera etc. because this novel shell body is the metal material, and has toughened glass, and shell body or toughened glass can not destroyed in the short time), can in time put through control circuit power, and the remote user is informed to the very first time.

As shown in fig. 1 and 2, when a person stays for a period of time at a farther detection distance at a doorway, a diode VD2 outputs a low level to enter a photodiode cathode concealed in an optical coupler a2 of a control circuit, or when the person approaches the doorway in a short distance and approaches the doorway for a short period of time, a diode VD1 outputs a low level to enter a photodiode cathode concealed in an optical coupler a2 of the control circuit, or when the person violently damages the door and enters the photodiode cathode concealed in an optical coupler a2 of the control circuit in real time, the diode VD3 outputs a low level to enter the photodiode concealed in the optical coupler a2, and infrared light is emitted; after the light receiving surface of a phototriode built in the optocoupler A2 receives infrared light, the collector of the phototriode built in the optocoupler A2 outputs low level to enter the negative power input end of a relay K1 (a miniature low-power relay), then, the relay K1 is electrified to attract the control power input end of the relay K1 to be closed with a normally open contact end, and as the control power input end of the relay K1 is communicated with the positive electrode of a 12V power supply, the normally open contact end is connected with the positive power input ends of a short message module A6, a camera A4 and a GPRS module A5, at the moment, the short message module A6, the camera A4 and the GPRS module A5 are electrified. After the short message module A6 is powered on and works, because the 3 feet and the 2 feet are grounded, the short message stored inside can be sent out under the action of the internal circuit, and the mobile phone of the user connected with the short message module A6 can hear the prompt in time and watch the video data of the home and the like sent by the subsequent GPRS module and received by the mobile phone or a PC (display screen display) after receiving the short message. The camera A4 can shoot the scene video after the work of getting electricity, and transmit to the far-end through the wireless mobile network through GPRS module A6, after the far-end user passes the message suggestion, receive the far-end video data and display the technology through the existing ripe cell-phone or PC, can know the various circumstances that the scene takes place directly perceivedly, grasp the scene situation in the very first time, and arrive the scene in the very first time or inform relevant departments to arrive the scene in time and stop the thief to continue stealing (if the guest that has arrived at home through the display screen, then the user can also arrive home in time or get in touch with the guest), has reduced user's economic loss as far as possible.

Fig. 1 and 2 show, in this novel, closely detect circuit, remote detection circuit detect the people and be close information back, as long as the people is apart from the preceding detection distance of opening the door, just no longer output video signal to the distal end, the user can not look over to the scene like this (also probably be that kids linger at the door and play and cause), can also more reach the economize on electricity effect under the safe prerequisite. Because the time that the door was destroyed to the emergence violence is few, and destroy and strike the door, in the time of destruction interval every twice, because mercury switch SQ internal contact can temporarily not submerged by mercury, if directly supply power through mercury switch SQ for opto-coupler A2, then can lead to opto-coupler A2 only to work in the extremely short time quantum, camera A4, GPRS module A5 also can work extremely short, can not transmit video data at all. Therefore, under the VS self-locking function of the novel unidirectional silicon controlled rectifier, as long as someone breaks the door and strikes the door once hard, the optocoupler A2, the camera A4 and the GPRS module A5 can work all the time, and the transmission of the field video data is ensured (the door is broken by violence rarely, so that the novel energy-saving effect is not obstructed). The specification of the adjustable resistor RP1 is 4M (adjusted to 2.72M), and the resistance value of RP is 2M (adjusted to 720K); resistor R, R2 is 470K; the resistances of the resistors R4, R3 and R1 are respectively 20K, 1K and 1.9K; relay K1 is a DC410012V minirelay; model numbers of NPN triode Q, Q1 and Q2 are 9013; the model of the electrolytic capacitor C, C1 is 10 mu F/25V; the models of the diodes VD1, VD2 and VD3 are 1N 4007; the VS model of the controlled silicon is MCR 100-1; the mercury switch SQ is a glass-case normally-open contact type universal mercury switch.
