Description

Technical Field

[0001] The present invention relates to the technical field of substation access control, and particularly to an electric movable door monitoring system controlled by a laser optical path. Background Art

[0002] At present, unattended operation has been realized in substations above 35 kV. While facilitating the work in the station, the security problems in the station have also become prominent. Among them, the intelligence of the first security line of the substation - the electric movable door is particularly important.

[0003] Although the existing electric door control systems, access control systems and image and video monitoring systems can realize the opening and closing of the door and a certain monitoring function, most of them are the integration of functions, with a single function performance and insufficient intelligence. In particular, they lack effective response functions for problems such as automatic opening or long-time opening without closing of the electric movable door in an unattended substation. When the door is opened for a long time without closing, it is impossible to truly give a pre-alarm or take scientific preventive measures, and it can only be closed on-site by the operating personnel or the maintenance unit after the problem is discovered, which brings serious potential safety hazards to the unattended substation.

[0004] Moreover, the existing electric door control systems, access control systems and image and video monitoring systems are in operation for a long time, with large daily losses, resulting in greater operating pressure.

[0005] Therefore, there are areas for improvement. The present invention provides an electric movable door monitoring system controlled by a laser optical path. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to propose an electric movable door monitoring system controlled by a laser optical path, and the specific scheme is as follows:

[0007] An electric movable door monitoring system controlled by a laser optical path includes a terminal controller, a laser, an optical path control mirror group, a fingerprint recognition device, an anti-mis-touch photosensitive device, a switch state photosensitive device, an audible and visual alarm device, a monitoring camera device and an electric movable door;

[0008] The audible and visual alarm device and the monitoring camera device are installed above the electric movable door, the fingerprint recognition device and the anti-mis-touch photosensitive device are installed in the middle of the electric door, the optical path control mirror group and the switch state photosensitive device are installed below the electric movable door, and the terminal controller and the laser are independently installed beside the opening side of the electric movable door;

[0009] The laser beam of the laser irradiates into the optical path control mirror group, and split laser A is separated by the optical path control mirror group and guided to the anti-mis-touch photosensitive device, and at the same time, split laser B is also separated and irradiated on the switch state photosensitive device;

[0010] The anti-mis-touch photosensitive device is electrically connected to the input end of the terminal controller. The output end of the terminal controller is electrically connected to the electric sliding door, the sound and light alarm device, and the monitoring camera device.

[0011] Thus, by whether the switch state photosensitive device senses the corresponding sub-laser B and feeds it back to the terminal controller, it is judged whether the electric sliding door is in the open state. By whether the anti-mis-touch photosensitive device senses the corresponding sub-laser A and feeds it back to the terminal controller, it is judged whether the electric sliding door is opened by the correct person. According to the received signal, the terminal controller makes corresponding actions, judges whether it is necessary to use the fingerprint recognition device for fingerprint recognition, whether it is necessary to use the sound and light alarm device for mis-touch alarm, and whether it is necessary to use the monitoring camera device to transmit the captured image, and then controls the electric sliding door to switch from the open state to the closed state, or from the closed state to the open state.

[0012] For the situation where an unknown person mis-touches the electric sliding door, or for the situation where the electric sliding door starts automatically or does not close for a long time, the sound and light alarm device will perform an alarm action, and the monitoring camera device will perform a shooting and transmission action.

[0013] This system simplifies the traditional redundant monitoring and sensing structure by using laser transmission and control, enables linkage control of mis-touch alarm, fingerprint recognition, and switch state monitoring, and at the same time provides a unified solution to problems such as anti-mis-touch, anti-theft, and anti-self-start, greatly improving the security reliability of the gate of the unattended substation.

[0014] Further, the fingerprint recognition device includes a handheld grip installed on the electric sliding door and a fingerprint recognition area provided on the outer surface of the handheld grip;

[0015] The anti-mis-touch photosensitive device includes a photosensitive sensor 1, which is provided on the inner surface of the handheld grip and is used to sense the sub-laser A from the mirror group.

[0016] Further, the switch state photosensitive device includes a mirror group and a photosensitive sensor 2. The mirror group receives the sub-laser from the optical path control mirror group and changes the irradiation direction. The photosensitive sensor 2 is used to sense the sub-laser B from the mirror group.

[0017] Further, the sound and light alarm device includes an alarm flashing light and an alarm horn.

[0018] Further, the optical path control mirror group includes a semi-reflective mirror group and a polarizing mirror provided beside the semi-reflective mirror group;

[0019] The semi-reflective mirror group receives the laser beam from the laser, and the semi-reflective mirror group reflects a beam of sub-laser and irradiates it on the switch state photosensitive device, and reflects multiple beams of sub-laser and irradiates them on the anti-mis-touch photosensitive device;

[0020] Multiple split lasers are split laser A, and one split laser is split laser B.

[0021] Furthermore, the terminal controller includes a signal feedback trigger module, an external signal acquisition module, an image temporary storage module, and a communication module that are communicatively connected to each other. The communication module is also communicatively connected to a central computer room;

[0022] Among them, the external signal acquisition module is communicatively connected to the fingerprint recognition device and the photosensitive sensors in the anti-mis-touch photosensitive device and the switch state photosensitive device;

[0023] The signal feedback trigger module is signal-connected to the electric sliding door, the monitoring camera device, the alarm flashing light, and the alarm horn, and the image temporary storage module is signal-connected to the monitoring camera device.

[0024] Furthermore, when the electric sliding door is in the closed state, the laser emits laser light, and both the switch state photosensitive device and the anti-mis-touch photosensitive device sense the laser light, and the alarm flashing light and the alarm horn do not trigger an alarm;

[0025] When the anti-mis-touch photosensitive device is continuously blocked for a certain period of time, it transmits a signal to the external signal acquisition module and the signal feedback trigger module. The fingerprint recognition device is triggered to perform fingerprint recognition within a specified time. If the recognition is successful, the fingerprint recognition pass signal is fed back to the external signal acquisition module and the electric sliding door is opened;

[0026] If the recognition is not successful within the specified time, the fingerprint recognition device transmits a signal to the signal feedback trigger module. The signal feedback trigger module controls the monitoring camera device to intercept and save the existing image and transmit it to the image temporary storage module, and uploads it to the central computer room through the communication module for information storage and subsequent use. At the same time, the signal feedback trigger module controls the alarm flashing light to flash and the alarm horn to beep.

[0027] Furthermore, when the electric sliding door is in the open state, the switch state photosensitive device records the number of openings and closings and the opening and closing duration.

[0028] Furthermore, when the electric sliding door is opened abnormally, the switch state photosensitive device transmits a signal to the external signal acquisition module, which transmits the signal to the signal feedback trigger module to control the electric sliding door to close automatically, controls the monitoring camera device to intercept and save the existing image and transmit it to the image temporary storage module, and uploads it to the central computer room through the communication module for information storage and subsequent use. At the same time, the signal feedback trigger module controls the alarm flashing light and the alarm horn to work.

[0029] Furthermore, the central computer room includes a display device, a storage device, and a call transmission device. The storage device stores the data obtained by the communication module. The display device is used to send an abnormal alarm prompt to the duty personnel, and the call transmission device is used for remote shouting during an abnormal alarm.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] (1) Compared with the prior art, the intelligent electric movable door monitoring system for a substation controlled by a laser optical path of the present invention solves the problem that the existing electric door control system, access control system, and image and video monitoring system have a single function performance. It realizes remote monitoring of the state of the electric movable door, enables timely alarm prompts in case of abnormalities, greatly improves the security reliability of the electric movable door in an unattended substation. The system only starts the monitoring camera device under certain conditions to collect video image information, reduces the operating pressure of the system, reduces daily losses, and improves the continuous operation ability under the condition of losing external power. Different response measures can be taken according to different severity levels of judged abnormal situations, so as to quickly and effectively handle them.

[0032] (2) The system adopts a complete set of laser control devices, including a laser, an optical path control mirror group, an anti-misoperation photosensitive device, a switch state photosensitive device, etc., to jointly control the normal detection of the fingerprint recognition of the staff entering the substation electric movable door, the misoperation alarm warning of unauthorized personnel, the alarm warning of abnormal self-starting or abnormal damage opening, and the statistical management of the number and duration of switches.

[0033] (3) Compared with the technical means of using a monitoring camera device to remotely monitor the electric movable door in real time to solve problems such as automatic opening or long-time opening without closing, the present invention is based on the combination of a laser, optical elements, and sensors. By simply monitoring whether the photosensitive sensor in the anti-misoperation photosensitive device is triggered, it can be obtained whether the electric movable door has been misoperated by an unknown person. By simply monitoring whether the photosensitive sensor in the switch state photosensitive device senses the laser, it can be quickly known whether the electric movable door has been opened, and then judge whether the electric movable door has been opened for a long time according to the opening duration, so as to monitor the real-time on-site situation of the electric movable door.

[0034] Moreover, the laser and optical elements of the present invention are only simple mechanical structures and will not cause pressure on the movement of the system, while the operating pressure of the sensor is small and the daily consumption is small. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Embodiment

[0039] The present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0040] As Figure 1 shown, a substation intelligent electric sliding door 1 monitoring system controlled by a laser optical path includes an electric sliding door 1, a device installed on the electric sliding door 1 for realizing misoperation alarm, fingerprint recognition, and switch state monitoring, a device installed on one side of the electric sliding door 1 for emitting a laser optical path, and a terminal controller 3 installed on one side of the electric sliding door 1. The terminal controller 3 is used to automatically monitor the real-time state of the electric sliding door 1 and collect and send on-site information to the central computer room 17, and realize the linkage control of misoperation alarm, fingerprint recognition, and switch state monitoring based on the terminal controller 3.

[0041] Among them, the electric sliding door 1 is a mechanical structure and can use products that can be purchased on the market. Generally speaking, intelligent electric sliding doors 1 on the market currently come with conventional fingerprint recognition devices. As Figure 2 shown, the fingerprint recognition device includes a handheld grip 6 installed on the electric sliding door 1 and a fingerprint recognition area 4 provided on the outer surface of the handheld grip 6, saving part of the equipment cost and installation cost. Secondly, the above-mentioned device for realizing misoperation alarm, fingerprint recognition, and switch state monitoring specifically refers to the combination of a switch state photosensitive device 11, a fingerprint recognition device, an anti-misoperation photosensitive device 5, an alarm flashing light 8, and an alarm horn 9. The monitoring camera device 7, the alarm flashing light 8, the alarm horn 9, etc. are also all products that can be directly purchased, and the models are not specifically limited.

[0042] As Figure 1As shown in the figure, the monitoring camera device 7, the alarm flashing light 8, and the alarm horn 9 can be sequentially arranged from left to right on the upper part of the electric sliding door 1, in a stable position to avoid displacement. The monitoring camera device 7 is directed at the electric sliding door 1 and can record the on-site situation around the electric sliding door 1 in real time from top to bottom. The handheld grip 6 is installed in the middle of the electric sliding door 1. The fingerprint recognition area 4 and the anti-mis-touch photosensitive device 5 are respectively arranged on the outer surface and the inner surface of the handheld grip 6, which conforms to ergonomics and is convenient for holding. When the hand holds the handheld grip 6, the thumb can just touch the fingerprint recognition area 4, and the palm part can just cover the area where the anti-mis-touch photosensitive device 5 is located.

[0043] The device for realizing the laser emission optical path mentioned above specifically refers to the combination of the laser 2 and the optical path control mirror group 10. The laser 2 is a low-power carbon dioxide laser 2, which is installed in the protection structure one on one side of the electric sliding door 1. To save space, the terminal controller 3 is also arranged in the protection structure one. The optical path control mirror group 10 is installed at the lower part of the electric sliding door 1, in the protection structure two on the side close to the laser 2. To cooperate with the optical path control mirror group 10, the switch state photosensitive device 11 is also installed at the lower part of the electric sliding door 1, in the protection structure three on the side far from the laser 2.

[0044] The protection structures one, two, and three can all adopt the same device, such as a protective box, to ensure that the laser 2, the optical path control mirror group 10, the switch state photosensitive device 11, and the terminal controller 3 are in a stable and solid space and are not damaged by the outside. In addition, to ensure the stability of the light source, the protection structure one needs to be in a static state and can be independently installed beside the opening side of the electric sliding door 1, such as installed on the wall. The internal structures of the protection structures two and three are coordinated with the protection structure one according to whether the electric sliding door 1 is opened. Therefore, to save the occupied space, without damaging the structural strength of the electric sliding door 1, an optical path is reserved in the electric sliding door 1 to ensure that the laser beam can be normally irradiated without hindrance, and the protection structures two and three can be built into the electric sliding door 1.

[0045] It should be noted that in the present invention, the optical path control mirror group 10, the anti-misoperation photosensitive device 5, and the switch state photosensitive device 11 do not directly adopt existing products. Their own structures, positions, and cooperation relationships are independently designed, and there are special position and cooperation relationships between the three and the laser 2. Among them, as shown in the figure, the position of the emission port corresponding to the laser 2 is at the lower part of the protection structure 1. In order to enable the laser beam to enter the protection structure 2 from the protection structure 1, four reflectors are provided between the two. Two parallel and inclined reflectors are in the protection structure 1, and the other two are symmetrically arranged beside the protection structure 2 with the edge of the electric sliding door 1 as the axis of symmetry. After the laser beam emitted from the emission port of the laser 2 is emitted, it is reflected by the two parallel and inclined reflectors in pairs and then enters the protection structure 2 in the directions of horizontally to the right, vertically upward, horizontally to the right, vertically downward, and horizontally to the right. The optical control mirror group includes a plurality of parallel and inclined semi-reflectors and a polarizer arranged beside the semi-reflectors. The laser beam entering the protection structure 2 is reflected by a part of the plurality of semi-reflectors and then uniformly passes through the polarizer and is projected vertically upward on the anti-misoperation photosensitive device 5, and the other part converges into a split laser beam. The switch state photosensitive device 11 includes two parallel and inclined reflector groups and a photosensitive sensor. The split laser beam coming out of the protection structure 2 is irradiated on the photosensitive sensor of the switch state photosensitive device 11 after being reflected by the two reflectors.

[0046] The above content is all about the positional relationship, installation relationship, etc. of the electric sliding door 1 and each device outside the electric sliding door 1. Combining Figure 3 , their specific control relationship is described as follows:

[0047] In this embodiment, the electric sliding door 1 is connected to the external power supply 16, and the external power supply 16 ensures that the electric sliding door 1 can continue to work in the case of external power failure. Similarly, the external power supply 16 can also be electrically connected to the fingerprint recognition device, the anti-misoperation photosensitive device 5, the monitoring camera device 7, the alarm flashing light 8, and the alarm horn 9, so that the external power supply 16 can also be used for power supply. Since the monitoring camera device 7, the alarm flashing light 8, and the alarm horn 9 are directly installed on the electric sliding door 1, and the three need to act according to the state of the electric sliding door 1, therefore, the three are also directly electrically connected to the electric sliding door 1 to facilitate control.

[0048] Since the fingerprint recognition device and the anti-misoperation photosensitive device 5 are installed on the hand grip 6 together, when the signal states of the fingerprint recognition device, the anti-misoperation photosensitive device 5, and the switch state photosensitive device 11 are different, they are respectively used to control the electric sliding door 1 to make different reactions. Therefore, the fingerprint recognition device, the anti-misoperation photosensitive device 5, and the switch state photosensitive device 11 can also be connected to each other for signal transmission.

[0049] The terminal controller 3 is a terminal for real-time monitoring of the electric sliding door 1 and collecting and transmitting on-site information. Specifically, it includes a signal feedback trigger module 12, an external signal acquisition module 13, an image temporary storage module 14, and a communication module 15. The four modules communicate with each other and are also connected to the electric sliding door 1, the fingerprint recognition device, the anti-misoperation photosensitive device 5, the monitoring camera device 7, the alarm flashing light 8, the alarm horn 9, and the switch state photosensitive device 11. Finally, it is fed back to the central computer room 17 by the communication module 15. In this way, the signal feedback trigger module 12, the external signal acquisition module 13, and the image temporary storage module 14 in the terminal controller 3 transmit relevant information to the central computer room 17 through the communication module 15 for information storage, facilitating subsequent processing.

[0050] In this embodiment, the terminal controller 3 is designed with multi-channel analog signal access according to the input signal type to complete the access of the anti-misoperation photosensitive device 5 and the switch state photosensitive device 11, and the same type of access terminals are designed according to the access port type of the monitoring camera device 7 to realize the acquisition and transmission of video images.

[0051] The signal introduction realizes signal preprocessing through designed functional modules such as filtering and amplification, further uses functional chips (MCU, DSP, FPGA, etc. are used according to requirements) to realize advanced signal processing, and finally accesses the dedicated network through the designed port connected to the network to complete the data transmission task and signal feedback.

[0052] In this embodiment, the central computer room 17 includes a display device, a storage device, and a call transmission device. The storage device stores the data obtained by the communication module 15. The display device is used to give an abnormal alarm prompt to the duty personnel. The call transmission device is used for remote shouting during abnormal alarms.

[0053] Among them, the external signal acquisition module 13 is used to receive signals from the fingerprint recognition device, the anti-misoperation photosensitive device 5, and the switch state photosensitive device 11 respectively, and is communicatively connected to the fingerprint recognition device, the anti-misoperation photosensitive device 5, and the switch state photosensitive device 11. Among them, the signal of the anti-misoperation photosensitive device 5 is whether it is continuously shaded within a certain period of time, targeting the personnel who want to open the electric sliding door 1, including maintenance staff who have entered fingerprints and unknown personnel who have not entered fingerprints. If someone holds the handheld grip 6, when the anti-misoperation photosensitive device 5 is continuously blocked for two seconds, the anti-misoperation photosensitive device 5 will feedback the recognized shading signal to the external signal acquisition module 13 and the signal feedback trigger module 12 to activate the fingerprint recognition device. The signal of the fingerprint recognition device is a fingerprint. The fingerprint recognition device mainly serves the maintenance staff. Since the maintenance staff will enter fingerprints in advance, when they want to open the electric sliding door 1 and touch the fingerprint recognition device, the fingerprint recognition device will feedback the recognized fingerprint signal to the external signal acquisition module 13 within the specified time. If it is an unknown person, similarly, the fingerprint recognition device will feedback the signal of not recognizing a fingerprint to the external signal acquisition module 13 within the specified time. The signal of the switch state photosensitive device 11 is whether a laser beam is sensed. The signal of sensing a laser beam represents that the electric sliding door 1 is closed, and not sensing a laser beam represents that the electric sliding door 1 is open. Both signals are transmitted to the external signal acquisition module 13 for recording the number of times and the duration of opening and closing of the electric sliding door 1.

[0054] The signal feedback trigger module 12 is used to receive signals from the external signal acquisition module 13 respectively and make feedback on these signals. If the state of the electric sliding door 1 is abnormal, it is necessary to save images, control the electric sliding door 1 to perform opening and closing actions, and control the alarm action. Therefore, the signal feedback trigger module 12 needs to be signal-connected to the electric sliding door 1, the monitoring camera device 7, the alarm flashing light 8, and the alarm horn 9. The monitoring camera device 7 also needs to be signal-connected to the image temporary storage module 14. The real-time image captured and recorded by the monitoring camera device 7, that is, the monitoring camera device 7 can transfer and store the video of the scene around the electric sliding door 1 to the image temporary storage module 14 and upload it to the central computer room 17 through the communication module 15, so as to record the scene around the electric sliding door 1 in real time.

[0055] In summary, when the substation uses the electric sliding door 1 and the monitoring system of the present invention, since the terminal controller 3 is installed in this system, the front-end signals are centrally collected and processed, and the system and the opening and closing of the electric sliding door 1 are controlled according to the information feedback shown by the acquired signals. Through the monitoring camera device 7, the real-time situation on the site is monitored. The monitoring camera device 7 is interconnected with the above-mentioned terminal controller 3 and is triggered to work under certain conditions by the terminal controller 3. Specifically as follows:

[0056] When there is no one on duty at the substation, the electric sliding door 1 is generally in the closed state. At this time, the split laser beam emitted by the laser 2 irradiates the photosensors in the switch state photosensing device 11 and the anti-touch photosensing device 5. The switch state photosensing device 11 and the anti-touch photosensing device 5 both sense normally, the monitoring camera device 7 does not take pictures, and the alarm flashing light 8 and the alarm horn 9 are not triggered.

[0057] When a person wants to open the electric sliding door 1, the person touches the handheld grip 6. When the anti-touch photosensing device 5 is continuously blocked for 2 seconds, it feeds back to the external signal acquisition module 13 and the signal feedback trigger module 12 to activate the fingerprint recognition device. After the fingerprint recognition device starts fingerprint recognition and lasts for 5 seconds, during this period, the maintenance staff who has entered their fingerprints can open the electric sliding door 1 through the entered personal fingerprints and return the signal to the external signal acquisition module 13;

[0058] If the fingerprint recognition pass signal is not returned within 5 seconds, the fingerprint recognition device transmits a signal to the signal feedback trigger module 12 to control the activation of the monitoring camera device 7, intercepts the existing image, saves it and transmits it to the image temporary storage module 14, and uploads it to the central computer room 17 through the communication module 15 for information storage and subsequent use. At the same time, the signal feedback trigger module 12 controls the alarm flashing light 8 to flash and the alarm horn 9 to beep, and can perform remote shouting through the central computer room 17, with an effective distance of 200 meters.

[0059] Moreover, when the electric sliding door 1 is opened, the split laser beam will deviate from the photosensor, and the switch state photosensing device 11 transmits the signal to the external signal acquisition module 13 to record the number of openings and the opening duration.

[0060] When the electric sliding door 1 is opened abnormally, that is, without passing through the fingerprint recognition device, the anti-touch photosensing device 5 starts automatically or is damaged illegally, the switch state photosensing device 11 transmits the signal to the external signal acquisition module 13, which transmits the signal to the signal feedback trigger module 12 to control the electric sliding door 1 to close automatically, controls the monitoring camera device 7 to intercept the existing image, saves it and transmits it to the image temporary storage module 14, and uploads it to the central computer room 17 through the communication module 15 for information storage and subsequent use. At the same time, the signal feedback trigger module 12 controls the alarm flashing light 8 and the alarm horn 9 to work.

[0061] It should be noted that the fingerprint recognition device and the anti-mis-touch photosensitive device 5 play a dual-insurance role in determining whether the electric sliding door 1 can be opened for different personnel. Normally, the maintenance staff who have registered their fingerprints know how to open the electric sliding door 1 normally. They only need to touch the fingerprint recognition area 4 without involving the anti-mis-touch photosensitive device 5. As long as they do not hold the handgrip 6, the anti-mis-touch photosensitive device 5 will not be blocked. In this way, the operation time of the anti-mis-touch photosensitive device 5 is reduced, thus alleviating the operation pressure of the system. For unknown personnel who have not registered their fingerprints and do not know how to open the electric sliding door 1 normally, as well as maintenance staff who are used to holding the handgrip 6, the anti-mis-touch photosensitive device 5 will transmit signals to the external signal acquisition module 13 and the signal feedback trigger module 12 only after they hold the handgrip 6 for a certain period of time. Then, the fingerprint recognition device will be activated for subsequent operations. In this way, the sequential actions of the anti-mis-touch photosensitive device 5 and the fingerprint recognition device also reduce the operation pressure of the system to some extent.

[0062] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
