Description

Technical Field

[0001] The present invention belongs to the field of remote control, and in particular relates to a method and a device for realizing remote switch control and real-time observation of a working scene by utilizing a camera rotation function. Background Art

[0002] The common remote control in the market has the following shortcomings: First, there is no remote video observation. The current cameras only have monitoring functions and do not remotely control the on-site device to perform a specific work function. In addition, the prices of remote switches controlled through the Internet (wifi) and through mobile communication networks (4G or 5G) are relatively high. Therefore, when you want to remotely control a switch for a specific application and be able to conduct remote work on-site observation at the same time, you must use the remote switch and the surveillance camera at the same time and control them separately (separately). In addition, you need to download and install the switch and camera control software separately on the mobile phone to log in to the remote terminal, so the overall work operation is more troublesome. Summary of the invention

[0003] In order to overcome the shortcomings of the existing methods, the present invention provides a method and device for remote switch control and work site monitoring based on the camera rotation function.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a method and device for remote switch control and work site monitoring. The content is to stick at least one piece of sensor sensing material or at least one sensor on the rotating part of the camera, and fix at least one sensor or at least one piece of sensor sensing material at a fixed position outside the rotating part of the camera. When the remote command from the remote mobile phone App or computer terminal causes the camera to rotate and the sensor sensing material to enter the sensor sensing area, the sensor generates a sensor signal due to the influence of the sensing material, and the signal enables the working switch to be remotely turned on, thereby realizing the visual remote work of a specific mechanical device. When the camera is rotated to separate the sensing material from the sensor sensing area, the sensor signal disappears, and the switch is remotely turned off. The present invention does not use a commercial remote switch alone, but uses the device that comes with the camera to realize remote control of the work site. Not only is the device cost low and easy to operate on site, but also through the on-site monitoring of the camera, remote visualization of work can be realized, making remote work easier to achieve and efficient.

[0005] The camera rotation function described in the present invention refers to the clockwise or counterclockwise rotation function of the camera in the horizontal direction when working, or the vertical rotation function of the camera optical window unit. It is preferred to use the horizontal rotation function to implement the present invention, but in some special occasions, the vertical rotation function of the camera can also be used. Or both rotation functions can be used at the same time.

[0006] The switch type sensor described in the present invention refers to a proximity switch (sensor), including (but not limited to) a Hall switch proximity sensor, an inductive proximity switch sensor, a capacitive proximity switch sensor, a magnetic transistor proximity switch sensor, and a reed switch proximity switch sensor. The above sensors belong to proximity switch sensors.

[0007] When the sensor is a Hall proximity switch sensor, the corresponding sensing material is a magnetic material.

[0008] When the sensor is a proximity inductive switch (also called an eddy current switch) sensor, the corresponding sensing material is a metal material.

[0009] When the sensor is a capacitive proximity switch sensor, the corresponding sensing material is other non-transparent solid materials except the rotating part of the camera, preferably metal materials.

[0010] When the sensor is a reed proximity switch sensor, the corresponding inductive material is a strong magnetic material.

[0011] When the sensor is a magnetic transistor (magnetic diode or magnetic transistor) proximity switch sensor, the corresponding sensing material is a magnetic material.

[0012] The proximity switch sensor of the present invention can be either a normally open type (NO) or a normally closed type (NC).

[0013] The sensor and the corresponding sensing material fixing method described in the present invention are commonly used (but not limited to) the following three methods, see Figure 2 , Figure 3 and Figure 4 .

[0014] Figure 2 This is a schematic diagram of the parallel arrangement of the sensor rod and the sensing material pasted on the rotating surface of the camera, that is, the entire sensor rod is parallel to the rotating surface of the camera, and the sensor head and the sensing material horizontally pasted on the rotating surface overlap to the maximum extent. At this time, the sensor is preferably a non-embedded sensor.

[0015] Figure 3 Schematic diagram showing that the sensor is fixed vertically by a fixing frame (fixed on a non-rotating surface) and the sensing surface of the sensing material is flat against the rotating surface of the camera.

[0016] Figure 4 The display sensor is horizontally (or overlapped) fixed by a fixing frame (fixed on a non-rotating surface), while the sensing material is vertically fixed on a bracket perpendicular to the camera's rotating surface.

[0017] The proximity switch sensor described in the present invention is preferably fixed at a fixed position outside the horizontal rotating housing of the camera. This fixed position can be a position on the camera base or a fixing device outside the camera as a whole (such as a wall or a fixed bracket rod for installing the camera, etc.). The preferred fixed position is a position on the base of the camera itself. The sensor is preferably fixed by an adjustable fixed arm fixed at a fixed position, and the sensor head and the sensing material on the rotating unit part are on the same horizontal plane. When working, the sensing head of the sensor at the top of the fixed arm overlaps the sensing area with the sensing material sheet (rod) by rotation (see the attached part of the instruction manual). Figure 1 ), so that the switch can be turned on remotely, thereby realizing the remote operation of a specific mechanical device. When the remote switch is to be turned off, just turn the camera to separate the corresponding areas of the sensor and the magnetic material.

[0018] Contrary to the above position setting, the sensing material and the sensor can also be exchanged to implement the present invention. That is, the sensing material is fixed on the base of the camera (or other fixed position), and the sensor is fixed on the rotating unit of the camera. This setting is not preferred.

[0019] When implementing the overall hardware design and production of the present invention, the position parameters of the sensor and the sensing material should be comprehensively considered based on the following factors: (1) It should be determined according to the specific camera size and operating parameters; (2) The type of switch sensor and its own parameter indicators; (3) The command characteristics of the remote operation software (the APP on the mobile phone or the program package on the computer). Only through the above comprehensive considerations and calculations can the best installation and debugging be achieved to achieve application optimization.

[0020] The composition and size of the sensing material of the present invention should be determined according to the parameters recommended by the selected switch sensor. Similarly, the distance between the sensor head and the sensing material surface should also be adjusted according to the parameter indicators of the selected sensor.

[0021] A question that may be asked is: when the sensor does not perform remote switching, and the camera needs to rotate separately for optical monitoring, the rotation at this time may generate unnecessary sensor switching operation, and thus may generate unnecessary sensor signals. This problem can be avoided by the following methods: (1) Make the camera quickly pass over the sensor head when it rotates continuously, and the signal is not stable and may not be transmitted; otherwise, the unnecessary sensor output signal can be avoided by (2), that is: (2) by adjusting the relay or (and) programmable logic controller (PLC) connected to the sensor to set the parameters so that the sensor's final output signal to the load is greater than the time when the sensing material and the sensor rotate relative to each other to generate the unnecessary output signal. At this time, the signal is not transmitted, that is, the remote switch does not output unnecessary signals.

[0022] Compared with the prior art, the method and device disclosed in the present invention for realizing remote control of switches and real-time observation of working scenes by using the camera rotation function have the following positive effects: Novelty: The common switch sensor is used to detect the existence of a certain substance or material, and the switch is in a "sensing" state: the present invention sets a certain material in advance and ingeniously turns on the switch sensor in a non-working state through rotation displacement to perform specific work. This is a reverse thinking invention. It is novel.

[0023] Creativity and practicality: The sensor is integrated with the camera to expand the function of the camera. Since the remote control switch is not used separately, it not only reduces the cost of using commercial remote switches, but more importantly, the camera can use its rotation function and optical observation performance to observe and control the operation of the device in the remote workplace in real time, better obtain the specific operation of the device on site, and make the remote operation more perfect and labor-saving. It is creative, novel and practical.

[0024] If the camera chooses to use a 4G or 5G mobile SIM card for control instead of relying on WLAN (wireless wifi) for control, the sensor will also not rely on the WLAN (wireless wifi) network. This is very suitable for applications without WLAN (wireless wifi) networks, especially for mobile outdoor or suburban applications (with a mobile power supply).

[0025] The switch is inside the sensor, and the switch function is realized by the inductive material outside the sensor. There is no external contact point, thus ensuring the safety of the switch when it is powered on, and there is no external contact safety hazard. BRIEF DESCRIPTION OF THE DRAWINGS

These implementation examples are only for the purpose of specific description or explanation, and are not intended to limit the scope of the present invention.

[0028] Embodiment 1 Reference Manual Attached Figure 1The device. A small round magnet is fixed with adhesive on the rotating unit of a self-assembled camera with horizontal rotation function. The magnet is attached at the position of the rotating unit's rotation center angle of about 30 degrees to the right when the optical camera window is directly in front (that is, the central symmetry line of the optical camera window is used as the reference line of the rotating unit, and the rotation angle of the rotating unit's center). A connecting rod is fixed on the non-rotating base of the camera base, and a switch-type Hall sensor (refer to Figure 3 , choose a normally open sensor). The sensor is connected to a relay through the output wire and the relay outputs AC power to the load device. When the rotating unit of the camera rotates to make the pasted magnetic induction material enter the sensing area of ​​the Hall sensor sensing head, the sensor outputs the working current required by the working device to realize the application of the working device. At this time, the camera can observe the operation of the device in a certain direction. When the rotating unit of the camera rotates to move the pasted magnet out of the sensing area of ​​the sensor sensing head, the sensor does not output the working current. At this time, the actual working device is closed and the specific application is ended. In the entire design and installation of this application, the position parameters of the sensor and the magnetic induction material should be installed and debugged according to the specific camera size and operating parameters using the camera's remote operation software (mobile phone APP or computer program package) to achieve application optimization. After completing the optimal installation and debugging, you can start the following specific application examples: (1) A small water pump is started by an appropriate sensor output voltage (usually 36V, 300mA), which draws water from a water tank to supply water to the flowers in the garden. At this time, the camera can observe the watering situation online in real time through its wide-angle monitoring function so that the water pump can be turned off at any time.

[0029] (2) Use the camera to capture animals. A metal net for capturing animals is equipped with a mesh door controlled by an electric switch. The output end of the sensor is connected to a relay to meet the 220-volt voltage requirement of the capture net. When the animal enters the capture net, the camera is rotated. When the magnet on the rotating unit rotates and enters the normally open Hall sensor head area, the mesh door opens; when the animal enters the capture net, the magnetic material is moved out of the sensor head by rotation, and the mesh door closes. At this time, the camera can observe the animal capture situation online in real time through its wide-angle monitoring function so that the next step can be taken at any time.

[0030] Embodiment 2 Reference Manual Attached Figure 4 and 5On the rotating unit of a self-assembled camera with horizontal rotation function, three pieces of sensing materials (two on the left are stainless steel and the one on the right is a magnet) are fixed with adhesive. On the non-rotating base of the camera base, two connecting rods are fixed. One end of the right connecting rod is fixed with a switch type Hall sensor (normally open type), and one end of the left connecting rod is fixed with a switch type eddy current sensor (normally open type). Each sensor is connected to a switch controlled by the sensor through a wire. When the rotating unit of the camera rotates to make the two sensors overlap with the two pieces of material on the right (the rightmost sensing material is a magnetic material and the middle sensing material is stainless steel) to generate a sensing signal, the two sensors will output two output current signals (A Hall signal and B eddy current signal), respectively. The two electrical signals trigger two relays respectively and simultaneously input current to two specific application device ends to realize the actual specific application of the device, achieving one of the applications. The specific applicable examples at this time are as follows: (1) The coordinated operation of moving products out of the furnace and spraying water for cooling on a metallurgical product line at the same time. (2) The coordinated operation of spraying two fire extinguishing agents at the same time at a fire scene.

[0031] When the rotation unit of the camera can only make the left sensor head sense the leftmost sensing material by rotating to the left, the right sensor does not output a trigger signal. At this time, only the left sensor B outputs a signal, executing the application in Example 1.

[0032] Embodiment 3 Reference Manual Attached Figure 1 , 2 and 6. On the rotating unit of a self-assembled camera with a horizontal rotation function, two pieces of sensing material (the left one is an aluminum sheet and the right one is a magnet) are fixed with adhesive, and two connecting rods are fixed on the non-rotating base of the camera base. A switch-type Hall sensor (normally open type) is fixed at one end of the right connecting rod, and a switch-type capacitive sensor (normally open type) is fixed at one end of the left connecting rod. Each sensor is connected to a switch controlled by the sensor through a wire. When the rotating unit of the camera rotates to the right so that the Hall sensor on the right overlaps with the magnetic material sheet on the right and generates an induction signal, the right sensor outputs a right sensor current signal. This circuit signal can be directly sent to the load device or input current to the device end of the specific application by triggering a relay to realize the actual specific application of the device, thereby achieving one of the applications. For specific applicable examples at this time, please refer to Example 1.

[0033] When the rotation unit of the camera can only make the left sensor head sense the leftmost sensing material by rotating to the left, the right sensor does not output a trigger signal. At this time, only the left sensor B outputs a signal, executing the application in Example 1.

[0034] Embodiment 4: Reference Manual Attached Figure 3 As described above. On the rotating unit of a self-assembled camera with a horizontal rotation function, three pieces of magnetic material are fixed with adhesive, and on the non-rotating base of the camera base, three connecting rods are fixed, and a Hall sensor (all of which are normally open) is fixed at the other end of each connecting rod. The sensor is connected to a switch controlled by the Hall sensor through a wire. When the rotating unit of the camera rotates to make the three sensor heads overlap with the three magnetic material sheets attached respectively to generate an induction signal, the three sensors output three output current signals respectively, and the three electrical signals trigger three relays respectively and input current to the three specific application device ends at the same time to realize the actual specific application of the device. When the rotating unit of the camera rotates to make the three attached magnetic material sheets move out of the induction area of ​​the three sensor heads, the three sensors do not output trigger signals. At this time, the three trigger transistor power switches are turned off, ending the output current of the specific application end and thus ending this specific application. Examples of specific applications include: (1) A farm adds three kinds of feed to a feed trough at the same time and monitors the animal's eating situation at the same time. (2) A remotely controlled collaborative operation of adding three kinds of drugs at the same time in a dangerous chemical synthesis.
