However, similar products on the market basically have a single function, except for the infrared motion detection triggering the alarm, there are no other functions. Users will not know whether the infrared detector is working properly, or if it has been damaged or stolen, until it is too late. On the other hand, if the user needs to leave the monitoring room for a short time, it is inevitable that some important incident alarms will be missed during this period, which is lacking and insufficient in the security function experience. Utility Model Content

[0003] The purpose of the utility model is to solve the problems existing in the prior art that similar products on the market generally have single functions, rigid performance requirements, short wireless distance, generally about 100 meters, lack of functional experience, one receiver with one infrared detection transmitter, or two, lack of signal prompt guidance from the transmitter, and no time prompt and review function, or some important incident alarms may be missed, and there are deficiencies and insufficiencies in security functions. A multi-defense zone long-distance infrared detection device is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The mounting mechanism is arranged on the infrared detection transmitter and is used for mounting the infrared detection transmitter.

[0007] In a possible design, the mounting mechanism includes a movable plate, a universal seat, a connecting plate and a mounting plate, one side of the movable plate is slidably connected to one side of the infrared detection transmitter, one side of the universal seat is fixedly connected to one side of the movable plate, a universal ball is movably connected in the universal seat, one side of the connecting plate is fixedly connected to one side of the universal ball, one side of the mounting plate is fixedly connected to one side of the connecting plate, and a mounting hole is provided on the mounting plate.

[0008] In a possible design, a slide groove is provided on one side of the infrared detection transmitter, a slider is fixedly provided on one side of the movable plate, and one side of the slider is slidably connected to an inner wall of one side of the slide groove.

[0009] In a possible design, first bolts are provided on both sides of the universal seat, and the first bolts are threadedly connected to the universal seat.

[0010] In a possible design, two second bolts are provided on one side of the moving plate, and the two second bolts are both threadedly connected to the moving plate.

[0011] In a possible design, a torsion bar is welded to one end of the first bolt and one end of the second bolt to facilitate the rotation of the first bolt and the second bolt.

[0012] In the present application, when in use, firstly, the infrared detection transmitter is installed according to the number of defense zones, and the infrared detection transmitter is installed in each defense zone. The installation steps are as follows: the infrared detection transmitter can be easily installed by the provided installation plate (it can be installed by screws). When the angle of the infrared detection transmitter needs to be adjusted, the infrared detection transmitter is rotated. The rotation of the infrared detection transmitter drives the movement of the movable plate. The movement of the movable plate drives the universal seat to move on the universal ball. The angle of the infrared detection transmitter can be adjusted to obtain an ideal detection area. After the adjustment, the twist bar is rotated. The rotation of the twist bar drives the rotation of the first bolt, so that one end of the first bolt is closely attached to one side of the universal ball. The universal seat can be limited to prevent rotation. When the infrared detection transmitter moves, the movable plate slides through the slide groove and the slider, so that the infrared detection transmitter can move on the movable plate. After the movement, the twist bar is rotated. The rotation of the twist bar drives the rotation of the second bolt, so that one end of the second bolt is closely attached to one side of the infrared detection transmitter. The infrared detection transmitter can be fixed to prevent sliding.

[0013] The infrared detection transmitter 1 uses three commonly used AA batteries, 4.5V power supply, the standby current of the whole machine is less than 30uA, and the energy consumption is low. The infrared motion detection probe uses a low-energy pyroelectric infrared sensing unit, and the chip circuit is integrated in the unit. The infrared detection transmitter is provided with a radio frequency transmission module. The chip completes the amplification, filtering, and shaping of small signals, and obtains an effective signal to send to the transmission module. After receiving the signal, the transmission module immediately transmits radio waves to the wireless receiver. The infrared detection circuit adopts a digital PIR unit, which has the advantages of stable performance, not easily interfered with and falsely triggered, and very low working current. The standby current of the digital PIR unit is less than 20uA. The low standby current can greatly extend the use time of the infrared detection transmitter. The wireless receiver is provided with a main control circuit, a wireless radio frequency receiving module, an indicator light circuit for each defense zone, a ringing circuit, and a time display circuit. Each infrared detection transmitter contains A unique fixed ID, multiple infrared detection transmitters have multiple different IDs. The RF transmitter encodes the ID and uses FSK modulation to send out radio waves at a carrier frequency of 433Mhz. It uses a 433Mhz carrier and has a good ability to bypass obstacles. FSK demodulation has a low bit error rate and stable performance. The wireless transmission distance is long, and the open distance is more than 800 meters, which meets the needs of a large number of users. Through the red warning light, when the human body is sensed in the sensing area, the red warning light will turn on to warn passers-by. When someone passes through the sensing defense area, the infrared detection transmitter will light up a red warning light and send radio waves to the wireless receiver at the same time. After the wireless receiver receives the wireless signal of the infrared detection transmitter, it can know which defense area the signal comes from by demodulating and identifying the ID, and then light up the indicator light of the defense area number, and drive the speaker to sound a ringtone, and at the same time remember the time point at this time to indicate to the user that someone has entered the defense area. The purpose of memorizing time points is to facilitate users to review incidents in the past time period. For areas where multiple incidents occur, inspections can be strengthened. If video surveillance cameras are installed near the defense area, surveillance videos can be reviewed according to the time of the incident to quickly find the required images.

[0014] The wireless receiver can be carried with you when needed and become a mobile wireless receiver. It only needs to be powered by 3 AA batteries. When it needs to be placed in a fixed position, there is a power input port on the top, which can be connected to DC 5V. Even if there is an occasional power outage, the device will switch to battery power and work will not be affected.

[0015] The volume button has 4 levels, and different volumes can be selected according to environmental changes. The ringtone selection button has 60 normal ringtones or alarm sounds to choose from, which is convenient for different users to choose from.

[0016] Ringtone selection / learn code button, short press to select the next ringtone, long press for 3 seconds to learn the code, when you need to add a transmitter, you can complete it through the learn code operation. Volume selection / clear code button, short press to select the volume, there are four volume levels to choose from, long press for 5 seconds to clear the code, clearing the code is to clear the ID code that the wireless receiver has memorized (referring to the inherent ID code of the infrared detection transmitter). After clearing, it will no longer receive and process signals from the infrared detection transmitter.

[0017] The time setting button allows the user to set the local time, and the incident time query button allows the user to press the query button and the time display screen will display each incident time point in the past one by one, and the corresponding defense zone indicator lights will light up at the same time.

[0018] The infrared detection transmitter radio frequency (RF) transmission module adopts the transmission chip CMT2119B, which is a high-performance FSK RF transmitter with an output power of up to 20dBm. The RF receiving module of the wireless receiver is the RF receiving chip CMT2219B, which is an ultra-low power, high-performance FSK receiver for wireless applications. The sensitivity of up to -121dBm optimizes the link performance of the application. CMT2219B, FSK modulation, 433MhZ carrier frequency, high sensitivity to achieve long-distance wireless work, the signal indicator number of the wireless receiver specifically corresponds to the infrared detection reflector defense zone number, the incident time record of each defense zone number can be queried, the query record can reach 20 or even more, real-time time display, sound and light coexistence prompts, the defense zone can be equipped with multiple or more infrared detection transmitters, only need to be equipped with a single wireless receiver, can achieve a wide range of security deployment in multiple defense zones; through the wireless signal using FSK modulation 433M carrier, high-sensitivity RF receiving module, easily reach a wireless working distance of more than 800 meters; the wireless receiver has multiple indicator lights corresponding to multiple defense zones; and incident time point record query.

[0037] Reference Figure 3 A slide groove 15 is provided on one side of the infrared detection transmitter 1 , and a slider is fixedly provided on one side of the movable plate 13 , and one side of the slider is slidably connected to an inner wall of one side of the slide groove 15 .

[0038] The above technical solution can reduce the friction generated during the movement of the moving plate 13 through the sliding groove 15 and the sliding block, so that the movement is smoother.

[0039] Reference Figure 3 First bolts 10 are provided on both sides of the universal seat 17 , and the first bolts 10 are threadedly connected to the universal seat 17 .

[0040] The rotation of the torsion bar 19 in the above technical solution drives the rotation of the first bolt 10, so that one end of the first bolt 10 is close to one side of the universal ball 18, which can limit the universal seat 17 to prevent rotation.

[0041] Reference Figure 3 Two second bolts 11 are provided on one side of the moving plate 13 , and the two second bolts 11 are both threadedly connected to the moving plate 13 .

[0042] The rotation of the torsion bar in the above technical solution drives the rotation of the second bolt 11, so that one end of the second bolt 11 fits against one side of the infrared detection transmitter 1, and the infrared detection transmitter 1 can be fixed to prevent sliding.

[0043] Reference Figure 3 A torsion bar 19 is welded to one end of the first bolt 10 and one end of the second bolt 11 to facilitate the rotation of the first bolt 10 and the second bolt 11.

[0044] The above technical solution can facilitate the rotation of the first bolt 10 and the second bolt 11 by providing the torsion bar 19 .

[0045] In this embodiment, see Figure 4 The red warning light and alarm sounder of the infrared detection transmitter will flash and sound an alarm when human movement is sensed in the infrared detection sensing area, which can deter intruders or stop their misconduct and attract the attention of staff to come for inspection. Another situation that can also cause the warning light and alarm to work is that when the infrared detection transmitter is subjected to unusual external force causing excessive vibration or shaking, its internal vibration sensor is triggered, and the trigger signal is sent to the RF transmission module, which sends a signal to the wireless receiver. The wireless receiver uses a specific prompt tone to remind the user that the infrared detection transmitter in the defense area is being damaged or stolen.

[0046] In this embodiment, see Figure 4The timed self-alarm circuit of the infrared detection transmitter can set the time interval of each self-alarm. For example, if it is set to self-alarm once every 24 hours, it will send a self-alarm signal to the wireless receiver every 24 hours to inform the wireless receiver whether the infrared detection transmitter is in good working condition at this time. If the wireless receiver does not receive the self-alarm signal of the infrared detection transmitter in the defense zone within 24 hours, the indicator light of the defense zone will be lit and a fault prompt sound will be issued to remind the user to go to the defense zone as soon as possible to troubleshoot the fault.

[0047] In this embodiment, see Figure 4 The low-battery detection circuit of the infrared detection transmitter. When the battery power is depleted to the lower limit, the infrared detection transmitter will send a low-battery signal to the wireless receiver. The indicator light of the wireless receiver in the defense zone will flash and a low-battery prompt sound will be emitted, prompting the user that the battery of the infrared detection transmitter in the defense zone is low and needs to be replaced.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
