Description

Technical Field

[0001] This utility model relates to the field of safety protection technology, specifically to an infrared beam sensor testing device. Background Technology

[0002] In key security areas such as airports, ammunition depots, high-level classified units, and nuclear power plants, security protection facilities are generally installed. With the rapid development of Internet of Things (IoT) technology, smart security has become a current development trend.

[0003] An infrared beam sensor is a device that uses infrared light for non-contact object detection. It can effectively detect unauthorized intrusions and is a commonly used security device. An infrared beam sensor consists of two parts: a transmitter and a receiver. When the infrared light emitted by the transmitter is blocked and cannot be received by the receiver, the alarm is triggered, alerting staff to the unauthorized intrusion.

[0004] However, whether the infrared beam sensor is functioning properly requires dedicated personnel to conduct regular on-site inspections, which wastes a lot of manpower and results in low testing efficiency. Therefore, there is an urgent need to design a new device to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide an infrared beam sensor testing device.

[0010] A power mechanism is provided, with one end mounted on the bracket and the other end connected to the shield. The power mechanism can drive the shield to move between a first position and a second position. When the shield is in the first position, the receiver can receive the infrared light emitted by the transmitter. When the shield is in the second position, the infrared light emitted by the transmitter is blocked by the shield, thus preventing the receiver from receiving it.

[0011] The controller is connected to the infrared beam sensor and the power mechanism.

[0012] Preferably, the direction of movement of the baffle is horizontal, vertical, or inclined.

[0013] Preferably, the shielding plate is provided with a through hole.

[0015] Preferably, both the first guide rail and the second guide rail have sliding grooves, and both sides of the baffle plate extend into the sliding grooves on both sides.

[0016] Preferably, the power mechanism is an electric cylinder.

[0017] Preferably, the electric cylinder includes a cylinder body and a telescopic rod, one end of the cylinder body is disposed on the bracket, one end of the telescopic rod extends into the interior of the other end of the cylinder body, and the other end of the telescopic rod is connected to the baffle plate.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention enables remote testing of the effectiveness of infrared beam sensors by installing a guide mechanism, a shield, and a power mechanism on-site. The remotely operable power mechanism drives the shield to move along the guide mechanism, thereby blocking or not blocking infrared light.

[0037] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0038] To reduce labor costs and improve testing efficiency, this utility model provides an infrared beam sensor testing device, including a bracket 1, a guide mechanism 2, a shield 3, a controller, and a power mechanism 4. The infrared beam sensor has a transmitter and a receiver. The guide mechanism 2 is configured on the bracket 1. The bottom of the guide mechanism 2 can be welded to the bracket 1 or fixed to the bracket 1 in a detachable manner.

[0039] It should be noted that the bracket 1 can be a plate-like structure or a structure combining a plate and a column, so as to facilitate the fixing of components such as the guide mechanism 2, the power mechanism 4, and the infrared beam sensor.

[0040] like Figure 1As shown, the shield 3 is mounted on the guide mechanism 2 and can slide under the guidance of the guide mechanism 2. The transmitter and receiver are respectively arranged on both sides of the shield 3. The movement of the shield 3 can block the infrared light emitted by the transmitter, so that the receiver cannot receive the infrared light. One end of the power mechanism 4 is mounted on the bracket 1, and the other end of the power mechanism 4 is connected to the shield 3. The controller signal is connected to the infrared beam sensor and the power mechanism 4. Preferably, the controller is connected to the infrared beam sensor and the power mechanism 4 through a cable or other communication means to realize signal transmission. The infrared beam sensor can feed back the sensing signal to the controller. The controller can issue a command to control the action of the power mechanism 4 as needed.

[0041] Furthermore, the power mechanism 4 can drive the baffle 3 to move between a first position and a second position. When the baffle 3 is in the first position, such as... Figure 1 As shown, the receiver can receive the infrared light emitted by the transmitter; when the shield 3 is in the second position, as... Figure 2 As shown, the infrared light emitted by the transmitter is blocked by the shield 3, thus preventing the receiver from receiving it. In this invention, the operator can remotely control the power mechanism 4 to move the shield 3 between the first and second positions via the controller, thereby testing the changes in the infrared light signal of the infrared beam sensor and thus testing whether the infrared beam sensor is in good condition. This eliminates the need for personnel to inspect each sensor on-site, greatly reducing labor costs and improving testing efficiency.

[0042] It should be noted that an infrared beam sensor is a device that uses infrared light for non-contact object detection. It includes a transmitter and a receiver. When the infrared light emitted by the transmitter is received by the receiver, the sensor outputs a received signal to the controller. Specifically, the transmitter contains an infrared light-emitting diode (LED). When the power is on, the infrared LED emits a continuous infrared beam. The receiver contains one or more infrared photosensitive elements, such as photodiodes, phototransistors, or photovoltaic cells. These photosensitive elements can receive and convert infrared light into electrical signals that are transmitted to the controller. When a person or object enters the path of the infrared beam, it will block or absorb some of the infrared light, causing the light intensity received by the receiver to weaken or disappear. Upon detecting this change, the receiver will change its output signal state, typically from high to low or from low to high. This signal change can be used by the controller to determine whether the infrared beam sensor is in good working order.

[0043] In practical applications, the baffle plate 3 is preferably a rectangular plate. The direction of movement of the baffle plate 3 can be set in various forms, such as horizontal, vertical, or inclined. When it is in an inclined direction, the angle between the axis of the baffle plate 3 and the horizontal direction is A, where A is greater than 0 and less than 90°. Figure 3 As shown.

[0044] like Figure 1 As shown, the shielding plate 3 is provided with a through hole 31. When the shielding plate 3 is in the first position, the infrared light emitted by the transmitter can pass through the through hole 31 and be received by the receiver. When the shielding plate 3 is in the second position, as shown... Figure 2 As shown, the position of the through hole 31 moves with the movement of the baffle plate 3. Since the position of the baffle plate 3 has changed, while the positions of the transmitter and receiver have not changed, the infrared light is blocked by the baffle plate 3, and the infrared light emitted by the transmitter cannot pass through the through hole 31.

[0045] like Figure 1 As shown, the guiding mechanism 2 includes a first guide rail 21 and a second guide rail 22. The first guide rail 21 and the second guide rail 22 are respectively arranged on both sides of the baffle plate 3 and slide in cooperation with both sides of the baffle plate 3. Specifically, both the first guide rail 21 and the second guide rail 22 have sliding grooves, and both sides of the baffle plate 3 extend into the sliding grooves on both sides. The sliding grooves guide the sliding direction of the baffle plate 3 on the one hand, and limit the movement of the baffle plate 3 along the direction perpendicular to the sliding direction on the other hand.

[0046] Specifically, the power mechanism 4 preferably adopts an electric cylinder, which includes a cylinder body 41 and a telescopic rod 42. One end of the cylinder body 41 is mounted on the bracket 1, and one end of the telescopic rod 42 extends into the interior of the other end of the cylinder body 41. The other end of the telescopic rod 42 is connected to the baffle plate 3. When the electric cylinder is energized, the telescopic rod 42 can extend out of the cylinder body 41 and become longer, or partially retract back into the cylinder body 41 and become shorter, thereby driving the baffle plate 3 to move forward or backward.

[0047] In order to adapt to the movement trajectory of the shield 3, the telescopic rod 42 and the shield 3 are rotatably connected. For example, the end of the telescopic rod 42 is rotatably connected to the shield 3 through a pivot.

[0048] This utility model also includes an alarm and a display screen. The controller is connected to the alarm signal. When the controller receives a signal from the infrared beam sensor that the infrared light is blocked, the alarm will sound. The alarm can be sound, light, or both. The alarm and the display screen are installed in the control room, which is convenient for the control room operator to remotely control and test the infrared beam sensor. The alarm can also alert the operator.

[0049] The working principle of this utility model is as follows:

[0050] When the infrared beam sensor reaches the specified detection time, the control room personnel remotely control the electric cylinder via the controller. At this time, the telescopic rod 42 extends from the cylinder body 41, and then the telescopic rod 42 pushes the shielding plate 3 from the first position to the second position. The infrared light emitted by the transmitter is blocked by the shielding plate 3, and the receiver cannot receive the infrared light. At this time, the signal is fed back to the controller. After receiving the signal, the controller displays the information that the infrared light is blocked on the display screen and transmits the signal to the alarm. At this time, the operator confirms through the display screen and the alarm that the infrared beam sensor can feed back the correct signal by controlling the movement of the shielding plate 3 to block the infrared light. Then, the telescopic rod 42 is retracted back into the cylinder body 41, and the telescopic rod 42 pulls the shielding plate 3 from the second position to the first position. The alarm disappears and the display screen shows that the infrared light is not blocked, indicating that the infrared beam sensor is still in normal working condition and has not malfunctioned. The test of the infrared beam sensor is thus completed.

[0051] To ensure the accuracy of test results, a camera can be installed on-site at the infrared beam sensor testing device. The camera's field of view covers the shield 3, allowing clear observation of whether the shield 3 and telescopic rod 42 are moving effectively. This prevents the electric cylinder malfunction from affecting normal testing and improves the device's practicality.
