Description

Detector

Technical Field

The utility model relates to a security protection technical field especially relates to a detector.

Background

In recent years, with the improvement of security awareness of people and the improvement of requirements on smart homes, intrusion detectors are widely applied to the fields of smart homes and security. The intrusion detector is used for detecting whether human body activity exists in the detection range of the intrusion detector, and when a person enters the detection range, the intrusion detector can give an alarm.

The installation mode of the existing intrusion detector usually comprises wall-mounted installation and ceiling type installation, and the detection angle and the detection range of the intrusion detector adopting the wall-mounted installation are different from those of the intrusion detector adopting the ceiling type installation. Generally, an intrusion detector only supports one installation mode, the number of applicable installation scenes is small, and practical application is limited greatly.

SUMMERY OF THE UTILITY MODEL

The embodiment of the application provides a detector, and the detector can support multiple mounting modes to be applicable to more installation scenes, promote product competitiveness.

The application provides a detector, including: the detector comprises a shell, a first fixing device and a second fixing device, wherein the shell is provided with a hollow cavity, and at least one part of the outer surface of the shell is a first mounting surface of the detector; the substrate is positioned in the hollow cavity of the shell; the substrate is provided with a first surface and a second surface which are oppositely arranged, and the first surface and the second surface are parallel to the first mounting surface; the intrusion detection assembly is arranged on the first surface of the substrate and is electrically connected with the substrate; and the inclination detection assembly is arranged on the first surface or the second surface and is electrically connected with the substrate.

It is to be understood that the present application provides a prober having a tilt sensing assembly disposed on either a first surface or a second surface of a substrate and electrically connected to the substrate. As can be seen from the above, at least a portion of the outer surface of the housing of the probe is the first mounting surface of the probe. In this case, when the probe is mounted on a building, the first mounting surface of the probe may be in abutment with a surface of the building, and thus the first mounting surface may be parallel to the surface of the building in abutment with the first mounting surface. Further, the first surface or the second surface on which the inclination detecting member is provided is parallel to the first installation surface, and thus, the first surface or the second surface on which the inclination detecting member is provided may be parallel to a surface of the building to which the first installation surface of the probe is attached. Thus, the inclination detection component (e.g., an inclination sensor) can determine the inclination degree of the first surface or the second surface through the inclination degree of the inclination detection component, and further detect the inclination degree of the detector. Alternatively, the inclination detecting assembly (e.g., a tilt sensor) may detect the inclination of the first mounting surface of the probe with respect to the horizontal plane by detecting the inclination of the first surface or the second surface on which the inclination detecting assembly is disposed, i.e., detecting the current inclination of the probe.

Therefore, the detector can determine the current installation mode of the detector through the inclination degree detected by the inclination detection assembly, and further automatically adjust the operation mode according to the determined installation mode. Therefore, the detector can normally operate in different installation modes, and therefore the detector can support multiple installation modes to be suitable for more installation scenes and has higher product competitiveness.

In one possible implementation, the housing includes: carrying a plate; the protective cover is provided with a hollow cavity and is detachably connected with the bearing plate; wherein, the bearing plate is kept away from the one side surface of protection casing and is first mounting surface.

It will be appreciated that the shield may function to protect the substrate, intrusion detection assembly and tilt detection assembly within the hollow cavity. And when the detector is installed, the bearing plate is only needed to be installed at the installation position of the detector, and then the protective cover is connected with the bearing plate, so that the operation is simple, and the installation is convenient. In addition, because the protection casing can be dismantled and connect on the loading board, when needs carry out operations such as maintenance or change of interior subassembly to this detector, only need lift off this protection casing, easy and simple to handle.

In another possible implementation, the housing includes: the first sub-shell is provided with a first accommodating cavity; the second sub-shell is provided with a second accommodating cavity; the first sub-shell is detachably connected with the second sub-shell, and the first accommodating cavity is communicated with the second accommodating cavity to form a hollow cavity; and the surface of one side of the first sub-shell, which is far away from the second sub-shell, is a first mounting surface.

In yet another possible implementation, the surface of the tilt detection assembly facing the substrate is a second mounting surface; the second mounting surface is parallel to the first surface of the substrate. Therefore, the placing direction of the inclination detection assembly is the same as that of the substrate, so that the inclination detection assembly can accurately detect the inclination degree of the substrate, namely the inclination degree of the detector.

In yet another possible implementation manner, the tilt detecting component includes: the insulating body is of a hollow structure; the first electrode body is connected with one end of the insulating body, and one part of the first electrode body extends into the hollow structure of the insulating body; the second electrode body is arranged at the other end in the hollow structure of the insulating body, the first electrode body and the second electrode body are oppositely arranged, and an accommodating space is formed between the second electrode body and the first electrode body in the hollow structure of the insulating body; the metal ball is arranged in the accommodating space, and the diameter of the metal ball is smaller than the distance between the first electrode body and the second electrode body; the detector is provided with a first installation position and a second installation position, and if the detector is located at the first installation position, the metal ball is in contact with the first electrode body and the first electrode body; if the detector is located at the second installation position, the metal ball is in contact with the first electrode body and has a distance with the second electrode body. It is understood that the above-described tilt detection assembly achieves both the on and off states of the conductive circuit of the tilt detection assembly through the contact between the metal ball and the first electrode body and the second electrode body. When the ball contacts the first electrode body and the first electrode body, the conductive circuit of the inclination detecting assembly is conducted, and the probe is located at the first mounting position at this time. When the metal ball is in contact with the first electrode body and has a distance from the second electrode body, the conductive circuit of the inclination detection assembly is broken, and the detector is located at the second installation position. In this manner, the detector can determine the installation position of the detector based on the state of the conductive circuit of the tilt detection assembly.

Optionally, the intrusion detection module includes: at least one of an infrared sensor, a radar sensor, a microwave sensor, or an ultrasonic sensor.

Fig. 1 is a schematic diagram of a detector according to the present application. As shown in fig. 1, the probe 100 includes: a base plate 1, an inclination detection assembly 2, an intrusion detection assembly 4 and a housing 5.

Wherein the housing 5 has a hollow cavity, and at least a portion of an outer surface of the housing 5 is a first mounting surface of the probe 100. The substrate 1 is positioned in the hollow cavity of the shell 5; the substrate 1 has a first surface 11 and a second surface 12 which are oppositely arranged, and the first surface 11 and the second surface 11 are parallel to a first mounting surface; an intrusion detection assembly 4, the intrusion detection assembly 4 being disposed on the first surface 11 of the substrate 1 and electrically connected to the substrate 1; and the inclination detection assembly 2 is arranged on the first surface 11 or the second surface 12, and the inclination detection assembly 2 is electrically connected with the substrate 1.

It should be understood that the probe 100 may be mounted on a stable plane, such as a wall or ceiling of a building, and the first mounting surface is the contact surface of the housing 5 of the probe 100 with the stable plane on which the probe 100 is mounted.

The substrate 1 may be used as a supporting component of the tilt detection module 2, the control module 3, and the intrusion detection module 4 in the detector 100, and may also be used as a carrier for electrically connecting the modules in the detector 100. Illustratively, the substrate 1 may be a Printed Circuit Board (PCB). Optionally, the detector 100 may further include a fastener such as a buckle or a hook, and the substrate 1 may be disposed on the housing 5 through the fastener.

The intrusion detection assembly 4 is used for detecting intrusion in the detection area of the detector 100. Optionally, the detector 100 provided in the embodiment of the present application may be an intrusion detector of a radar type detector, a microwave wall type detector, an active infrared detector, or an ultrasonic type detector. Thus, the intrusion detection assembly 4 may be a sensor assembly within an intrusion detector such as an infrared sensor, a radar sensor, a microwave sensor or an ultrasonic sensor.

Alternatively, the housing 5 may be a unitary structure.

Alternatively, the housing 5 may be formed of one or more sub-housing connections for ease of installation.

Alternatively, as shown in fig. 1, the housing 5 includes a carrier plate 51 and a protective cover 52, the protective cover 52 has the hollow cavity, and the protective cover 52 is detachably connected to the carrier plate 51. Wherein, a side surface of the loading plate 51 away from the shield 52 is the first mounting surface.

It will be appreciated that the shield 52 may function to protect the substrate 1, intrusion detection assembly 4 and tilt detection assembly 2 within the hollow cavity. In addition, when the detector 100 is installed, the bearing plate 51 is only needed to be installed at the installation position of the detector 100, and then the protective cover 52 is connected with the bearing plate 51, so that the operation is simple, and the installation is convenient. In addition, since the protective cover 52 is detachably attached to the carrier plate 51, when the probe 100 needs to be repaired or replaced by other internal components, the protective cover 52 is only required to be removed, and the operation is simple.

Optionally, as shown in fig. 2, the housing 5 includes a first sub-housing 53 and a second sub-housing 54, where the first sub-housing 53 has a first accommodating cavity, the second sub-housing 54 has a second accommodating cavity, and the first sub-housing 53 is detachably connected to the second sub-housing 54, and the first accommodating cavity is communicated with the second accommodating cavity to form a hollow cavity of the housing 5. Further, a side surface of the first housing 51 away from the second housing 52 is a first mounting surface.

The tilt detection unit 2 detects the degree of tilt of the probe 100 and outputs a tilt signal of the probe 100. Wherein the surface of the tilt detecting member 2 facing the substrate 1 is a second mounting surface, and the second mounting surface is parallel to the first surface 11 of the substrate 1. In this manner, the tilt sensing assembly 2 senses the degree of tilt of the probe 100.

It should be understood that the first surface 11 and the second surface 12 of the substrate 1 are parallel to the first mounting surface, and the second mounting surface is parallel to the first surface 11 of the substrate 1, and the inclination detecting assembly 2 is disposed in the same direction as the substrate 1, that is, the substrate 1 is inclined to the same degree as the detector 100, so that the inclination detecting assembly 2 can be used to detect the inclination degree of the detector 100.

Alternatively, the tilt sensing assembly 2 may be a tilt sensor, or the like capable of sensing the degree of tilt of the detector 100.

Alternatively, fig. 3 is a sectional view of an inclination sensor, which includes, as shown in fig. 3, a first electrode body 21, a second electrode body 22, a metal ball 23, and an insulating body 24.

The insulating body 24 may have a hollow structure. The first electrode body 21 is connected to one end of the insulating body 24, and a part of the first electrode body 21 protrudes into the hollow structure of the insulating body 24. The second electrode body 22 is disposed at the other end in the hollow structure of the insulating body 24, and the first electrode body 21 is disposed opposite to the second electrode body 22, and an accommodating space is formed between the second electrode body 22 and the first electrode body 21 in the hollow structure of the insulating body 24. The metal ball 23 is disposed in the accommodating space, and the diameter of the metal ball is smaller than the distance between the first electrode body 21 and the second electrode body 22.

Wherein the probe 100 has a first mounting position and a second mounting position, and if the probe 100 is located at the first mounting position, the metal ball 23 is in contact with the first electrode body 21 and the second electrode body 22; if the probe 100 is located at the second mounting position, the metal ball 23 is in contact with the first electrode body 21 with a space from the second electrode body 22.

Illustratively, the first mounting location may be a stable horizontal plane extending in a horizontal direction, such as a door frame top, a ceiling, or the like. The first mounting position may be on a stable plane, such as a wall, extending perpendicular to the horizontal direction. Wherein the horizontal direction is perpendicular to the direction of gravity.

If the shape of the second electrode body 22 or the first electrode body 21 is irregular, the distance between the second electrode body 22 and the first electrode body 21 is the minimum distance between the first electrode body 11 and the second electrode body 22.

Optionally, the tilt sensor further comprises electrically conductive circuits electrically connected to the first electrode body 21 and the second electrode body 22, respectively.

As shown in fig. 3 (a), the tilt sensor is placed in the X-axis direction, and in the rectangular coordinate system in fig. 3 (a), the X-axis direction is the horizontal direction and the Y-axis direction is the vertical direction, and at this time, the tilt sensor is in the horizontal state. Wherein the metal ball 23 can contact the first electrode 21 and the second electrode 22 simultaneously, and at this time, the conductive circuit of the spherical tilt sensor is in a conductive state, the tilt signal output by the spherical tilt sensor can be level data when the circuit is conductive, such as 5 volts, 9 volts, etc. As shown in fig. 3 (b), the tilt sensor is placed in the Y direction, and in the rectangular coordinate system in fig. 3 (b), the X-axis direction is the horizontal direction and the Y-axis direction is the vertical direction, and at this time, the tilt sensor is in the vertical state. Wherein, under the influence of the gravity of the metal ball 23, an accommodating space is formed between the second electrode body 22 and the first electrode body 21, and the metal ball 23 falls onto the first electrode body 21. At this time, the metal ball 23 contacts only the first electrode body 21 and does not contact the second electrode body 22, and the conductive circuit of the tilt sensor is in an off state, so that the tilt signal output from the tilt sensor may be level data when the conductive circuit is off, for example, 0 v. Wherein, the vertical direction is a direction perpendicular to the horizontal direction.

For another example, the tilt sensing unit 2 may be a tilt sensor. The device is a device capable of measuring the inclination of a measured plane relative to a horizontal plane, the mutual parallelism of two parts and the perpendicularity. In the embodiment of the present application, the tilt sensor may be configured to detect the inclination between the substrate 1 and the horizontal plane and output, for example, angle values of 0 °, 1 °, and 90 °. The horizontal plane, which is a plane formed by water that is relatively completely still, also refers to a plane parallel to this plane, and is generally a plane extending in the horizontal direction. When the probe 100 is in the first mounting position, the first mounting surface of the probe 100 is parallel to a horizontal plane. When the probe 100 is in the second mounting position, the first mounting surface of the probe 100 is perpendicular to the horizontal plane.

The control component 3 may be a control Unit (MCU), such as a single-chip microcomputer, or the like. The control unit 3 is connected to the tilt detecting unit 2, so that the control unit 3 can receive the tilt signal outputted from the tilt detecting unit 2. The control unit 3 can thus determine the manner in which the probe 100 is mounted on the basis of the inclination signal.

Optionally, the installation mode includes ceiling installation and wall-mounted installation.

Wherein the ceiling mounting corresponds to the first mounting location. When the detector 100 is mounted in a first mounting position, such as on the top of a door frame, a ceiling, etc., the detector 100 can detect intrusion downward. As shown in fig. 1, the loading plate 51 of the probe 100 is fixed to the ceiling, and the mounting surface of the probe 100 (i.e., the contact surface of the loading plate 51 with the ceiling) is parallel to the horizontal plane. At this time, the tilt detecting unit 2 is in a horizontal state.

The wall-mounted installation corresponds to the second installation position. As shown in fig. 4, the loading plate 51 of the detector 100 is fixed to a wall perpendicular to the horizontal direction, and at this time, the mounting surface of the detector 100 (i.e., the contact surface of the loading plate 51 with the wall) is perpendicular to the horizontal plane. At this time, the tilt detecting assembly 2 is in the above-described upright state.

It should be noted that, in actual use, the ceiling installation or the wall-mounted installation can be selected according to the specific environment of intrusion detection. For example, in an installation environment such as a hall where a space is large and a stable plane perpendicular to a horizontal plane is small, a ceiling installation method may be adopted. For another example, in an installation environment that needs to be installed indoors for intrusion detection on windows, balconies, and aisles, the detector may be installed on a wall in a wall-mounted manner, so that the detector may face a detection area such as a window, a balcony, and an aisle for detection.

In a first possible implementation, the different mounting modes of the probe 100 correspond to different tilt signals of the tilt detection assembly 2. Therefore, the control unit 3 can determine the installation mode of the probe 100 according to the inclination signal.

Optionally, when the installation mode of the detector 100 is ceiling-mounted, the tilt signal detected by the tilt detection assembly is a first tilt signal; when the detector 100 is mounted on a wall, the tilt signal is a second tilt signal.

Specifically, when the tilt signal is a first tilt signal, such as 5 volts, the control module 3 may determine that the probe 100 is mounted in a ceiling-mounted manner. Alternatively, the control component 3 may determine that the detector 100 is mounted on a wall when the tilt signal is a second tilt signal, for example, 0 v.

It should be noted that, in one aspect, when the detector 100 is initially used, the control component 3 may determine the installation mode of the detector 100 according to the inclination signal before the detector 100 starts to operate, so that the detector 100 operates normally. On the other hand, during operation of the detector 100, the installation of the detector 100 may be adjusted, for example, from ceiling-mounted to wall-mounted, due to changes in the actual practical requirements of the user. When the detecting component 2 detects that the inclination degree of the detector 100 changes, the detecting component 2 outputs a current inclination signal to the control component 3. Accordingly, the inclination signal received by the control component 3 may also change, and at this time, the control component 3 may determine the installation mode of the detector 100 according to the inclination signal, so as to adjust the operation mode of the detector 100.

The first tilt signal is a tilt signal output when the tilt detection unit 2 is in a horizontal state as shown in fig. 3 (a). For example, the first tilt signal may be, for example, non-0 level data, such as level data when the tilt sensor circuit is turned on, for example, 5 volts, 9 volts, and the like. Alternatively, the first tilt signal may be, for example, an arbitrary angle value within the first range. The first range is a reasonable angular range including 0, such as-1 to 1, -1 to 2, etc. It will be appreciated that the angular value of the tilt sensor output in the first range may indicate that the substrate 1 is parallel or approximately parallel to the horizontal plane.

Accordingly, the second tilt signal is a tilt signal output when the tilt detecting assembly 2 is in the vertical state. For example, the second tilt signal may be level data when the tilt sensor circuit is not turned on, such as 0 v. Alternatively, the second tilt signal may be, for example, an arbitrary angle value within the second range. The second range is a reasonable angular range including 90 °, such as 89-91 °, 89-92 °, and so on. It will be appreciated that the angular value of the tilt sensor output in the second range may indicate that the substrate 1 is perpendicular or approximately perpendicular to the horizontal plane.

When the probe 100 is mounted in the ceiling-mounted manner, the probe 100 is in a horizontal state and outputs a first inclination signal. When the detector 100 is mounted on a wall, the detector 100 is in a vertical state and outputs a second inclination signal. Therefore, when the inclination signal is 5 v, the control unit 3 can determine that the detector 100 is in a horizontal state, and thus determine that the detector 100 is installed in a ceiling-mounted manner. Accordingly, when the inclination signal is 0 v, the control component 3 may determine that the detector 100 is in the vertical state, and may determine that the detector 100 is installed in a wall-mounted manner.

In a second possible implementation manner, when the installation manner of the detector is ceiling installation, the inclination signal is a first inclination signal, and the duration is greater than a first time threshold; when the detector is installed in a wall-mounted mode, the inclination signal is a second inclination signal, and the duration time is greater than a second duration threshold.

The control unit 3 can thus determine the manner in which the probe 100 is mounted, based on the above-mentioned inclination signal and the duration of this inclination signal.

Specifically, the control unit 3 acquires the duration of the tilt signal. And when the inclination signal is a first inclination signal and the duration is greater than a first time threshold, determining that the installation mode of the detector 100 is ceiling installation. Or, when the inclination signal is a second inclination signal and the duration is greater than a second duration threshold, determining that the installation mode of the detector 100 is wall-mounted.

Further, the first time threshold may be, for example, 5 seconds, 10 seconds, or other reasonable time. Accordingly, the second time threshold may be, for example, 5 seconds, 10 seconds, or other reasonable time. It should be understood that the second duration threshold may be the same duration as the first duration threshold, or may be a different duration.

It should be noted that, if the detector 100 may shake under the influence of environmental factors such as gust and obstacle collision, the tilt signal output by the tilt detection assembly 2 may change continuously. Moreover, if the user adjusts the installation mode during the use of the probe 100, the tilt signal output by the tilt detection assembly 2 may also change continuously. Generally, when the duration of a tilt signal is greater than the duration threshold, the orientation of the probe 100 is stable and may be installed. Therefore, the control unit 3 can determine the installation mode of the probe 100 more accurately in the case where the orientation state of the probe 100 is changed continuously, based on the tilt signal and the duration of the tilt signal.

In some embodiments, the control assembly 3 may further control the detector 100 to operate in a predetermined operation mode according to the installation manner. Also, different mounting configurations of the detector 100 correspond to different operating modes of the intrusion detection assembly.

Optionally, the preset operation mode may include a first operation mode and a second operation mode.

For example, when the control assembly 3 determines that the detector 100 is currently mounted in a ceiling-mounted manner, the detector 100 is controlled to operate in a first mode of operation. In this case, the first operation mode corresponds to the ceiling-mounted manner.

For another example, when the control component 3 determines that the current installation mode of the detector 100 is wall-mounted, the detector 100 is controlled to operate in the second operation mode. In this case, the second operation mode corresponds to the ceiling-mounted manner.

For example, as shown in fig. 5, when the installation manner of the probe 100 is ceiling-mounted, the tilt signal output by the tilt detection assembly 2 is a first tilt signal, and the probe 100 can operate in a first operation mode; when the detector 100 is mounted on a wall, the tilt signal is a second tilt signal, and the detector 100 can operate in a second operation mode.

The intrusion detection assembly 4 is configured to perform intrusion detection on a first detection area to acquire a first signal when the detector 100 is operating in the first operating mode. And, when the intrusion detection assembly 4 determines that there is an intruder within the first detection area, the first signal is greater than the first signal threshold.

The first signal is a signal detected by the intrusion detection module 4 in the first detection area, and the first signal threshold is a minimum signal value that the intrusion detection module 4 may detect when an intruder occurs in the first detection area.

Illustratively, as shown in fig. 6 (a), the ceiling of the detector 100 is installed at 2.5 meters, the detector 100 is in a horizontal state, and the detector 100 detects from top to bottom. At this time, the detection region of the detector 100 may be approximated as the first detection region 61 as shown in (b) of fig. 6. At this time, the intrusion detection module 4 performs intrusion detection on the first detection area 61, and the obtained signal is the first signal.

The intrusion detection assembly 4 is configured to perform intrusion detection on a second detection area to obtain a second signal when the detector 100 is operating in the second operation mode. And, when the intrusion detection assembly 4 determines that an intruder is within the second detection area, the second signal is greater than the second signal threshold.

The first signal is a signal detected by the intrusion detection module 4 in the first detection area, and the second signal threshold is a minimum signal value that the intrusion detection module 4 may detect when an intruder occurs in the second detection area.

Illustratively, as shown in fig. 7 (a), the detector 100 is installed at 2.5 meters on wall, and the detector 100 is in a vertical state. At this time, the detection region of the detector 100 may be approximated as the second detection region 62 as shown in (b) of fig. 7. At this time, the intrusion detection module 4 performs intrusion detection on the second detection area 61, and the obtained signal is the second signal.

Note that, as shown in fig. 6 (b) and fig. 7 (b), even if the height of the ceiling-mounted detector 100 is the same as that of the wall-mounted detector, it is obvious that the first detection area 61 is different from the second detection area 62. Thus, for the same intruder, the first signal detected by the intrusion detection assembly 4 in the first detection zone 61 is different from the second signal detected in the second detection zone 62, and thus the first signal threshold when the detector 100 is top mounted and operated in the first operating mode is different from the second signal threshold when the detector 100 is wall mounted and operated in the second operating mode.

Therefore, if the detector 100 is installed in a ceiling-mounted manner and the detector 100 operates in the second operating mode, the detector 100 determines whether there is an intruder or not by using the second signal threshold value because the first signal threshold value and the second signal threshold value of the same installation height are different, and the probability of false alarm and missed alarm is high.

Therefore, before the detector starts to work, the current installation mode is determined through the inclination sensor, so that the detector can adjust the working mode according to the determined installation mode, and the detector can normally work under the two installation modes.

Based on the detector provided by the application, at least the following beneficial effects can be produced: the utility model provides an increase the slope detection subassembly on the detector, this slope detection subassembly sets up on first surface or second surface, and is connected with the base plate electricity to, this slope detection subassembly can detect the current slope degree of detector.
