[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0028] Example 1
[0029] Reference Figures 1-7This is the first embodiment of the present invention. This embodiment provides a switch cabinet that facilitates the backend acquisition of the drawer position status. The switch cabinet that facilitates the backend acquisition of the drawer position status includes a component 100, including a cabinet body 101. A slide rail 102 is fixed on the cabinet body 101. A drawer 103 is provided on the slide rail 102. The drawer 103 includes a side panel 103a. A front panel 103b, a rear panel 103c, and a bottom panel 103d are fixed on the side panel 103a. A slider 103f corresponding to the slide rail 102 is fixed on the bottom panel 103d. Through the cooperation of the slide rail 102 and the slider 103f, the drawer 103 can move stably.
[0030] The monitoring component 200 is located on one side of the drawer 103 and includes a fastener 201. A sensor 202 is provided on one side of the fastener 201. A light shield 203 is fixed on the side panel 103a. The fastener 201 is used to fix the sensor 202 to the cabinet 101.
[0031] The fastener 201 includes a mounting plate 201a fixed to the slide rail 102. A fixing block 201b is also fixed to the slide rail 102. The fixing block 201b has a sliding groove 201b-1. A mounting block 201c is fixed to one side of the sensor 202. The mounting block 201c is used to assist in the installation of the sensor 202. The mounting block 201c can slide in the sliding groove 201b-1. Through the cooperation of the mounting block 201c and the fixing block 201b, the sensor 202 is fixed in the designated position.
[0032] Sensor 202 is a through-beam photoelectric sensor, which consists of a transmitter and a receiver. The transmitter emits light, and the receiver receives the light. This is existing technology, and this solution will not elaborate further. Moreover, those skilled in the art can clearly understand the working principle. When there is no obstruction in the middle, the receiver can receive the light, and the sensor outputs a signal state. When the light is blocked by the light shield 203, the receiver cannot receive the light, and the sensor outputs another signal state. Based on this principle, by using three sets of through-beam photoelectric sensors, different opening states of drawer 103 can be accurately detected according to different obstruction conditions, and the signals can be transmitted to the background system.
[0033] There are two mounting plates 201a, located on both sides of drawer 103. There are three sets of sensors 202, each consisting of a transmitter and a receiver, which are mounted on the two mounting plates 201a to ensure that the light emitted by the transmitter can be accurately received by the receiver. The light shield 203 is at the same horizontal height as the sensor 202, which can accurately block the light from the photoelectric sensor to achieve different light blocking effects at different opening positions.
[0034] When drawer 103 is in the closed position, the light shield 203 completely blocks the light from the three sets of through-beam photoelectric sensors. At this time, the receiving end of the photoelectric sensor cannot receive the light emitted by the transmitting end, and the photoelectric sensor outputs a low-level signal. The signal processing module amplifies and filters the low-level signal and then transmits it to the microcontroller. After receiving the low-level signals from the three sets of sensors 202, the microcontroller determines that drawer 103 is in the closed state according to the preset logic and sends the "drawer closed" status information to the background system through the communication module. After receiving the information, the background system displays that drawer 103 is in the closed state on the interface.
[0035] When drawer 103 is opened, as drawer 103 moves, the light shield 203 gradually moves away from the detection area of the innermost set of photoelectric sensors. The receiving end of this set of sensors 202 can receive the light emitted by the transmitting end, thereby outputting a high-level signal. The other two sets of sensors 202 are still blocked by the light shield 203 and output low-level signals. The signal processing module processes the signals of these three sets of sensors 202 and transmits them to the microcontroller. The microcontroller determines that drawer 103 is in a partially open state based on the combination of received signals and calculates the approximate opening position of drawer 103. Then, the microcontroller sends the partially open state of the drawer and the corresponding position information to the background system through the communication module. After receiving the information, the background system updates and displays the current position and status of drawer 103 on the interface.
[0036] As drawer 103 continues to open until the light shield 203 completely leaves the detection area of the three sets of photoelectric sensors, the receiving ends of the three sets of sensors 202 can all receive light and output high-level signals. The signal processing module processes the signals and transmits them to the microcontroller. The microcontroller determines that drawer 103 is in a fully open state and sends the "drawer fully open" information to the background system through the communication module. The background system updates the display on the interface accordingly to show that the status of drawer 103 is fully open.
[0037] Throughout the operation, sensor 202 detects changes in drawer position in real time through light shield 203. The signal processing module and microcontroller process and judge the sensor signals, and the communication module realizes data transmission with the back-end system, thereby realizing the monitoring and back-end display functions of the real-time position of the switch cabinet drawer opening.
[0038] Example 2
[0039] Reference Figures 1-7 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0040] Specifically, the fixed block 201b has a moving groove 201b-2, and a limit block 201d is provided in the moving groove 201b-2. A spring 201e is fixed to one end of the limit block 201d, and the spring 201e applies a continuous pushing force to the limit block 201d. The other end of the spring 201e is fixed to the inner wall of the moving groove 201b-2.
[0041] When installing sensor 202, mounting block 201c slides within slide groove 201b-1, and the bottom of mounting block 201c contacts slide rail 102. There are two limiting blocks 201d, which are used to limit the position of mounting block 201c within slide groove 201b-1 to prevent the bottom of mounting block 201c from separating from slide rail 102. This prevents sensor 202 from shifting position due to collision between drawer 103 and cabinet 101 during multiple opening and closing of drawer 103.
[0042] Specifically, one end of the limiting block 201d is arc-shaped. Due to this arc shape, when the sensor 202 is installed, the end face of the mounting block 201c will first contact and press against the arc end face of the limiting block 201d, thereby compressing the spring 201e. The limiting block 201d will then move into the moving groove 201b-2, thus not hindering the movement of the mounting block 201c. As the mounting block 201c moves, its end face no longer presses against the limiting block 201d. At this time, the mounting block 201c is in contact with the slide rail 102. Under the push of the spring 201e, the limiting block 201d protrudes from the inner wall of the slide groove 201b-1, preventing the mounting block 201c from separating from the slide rail 102. The spring 201e has a large elastic force, so when the drawer 103 is opened and closed, the spring 201e will not be compressed, thus limiting the movement of the mounting block 201c and preventing the sensor 202 from changing position.
[0043] Specifically, there are three sensors 202 and three mounting blocks 201c, each corresponding to one of the sensors 202.
[0044] Specifically, one mounting block 201c corresponds to two fixing blocks 201b. The top of the fixing block 201b protrudes from the end face of the mounting plate 201a. Since the operator's line of sight is obstructed when installing the sensor 202, the protruding fixing block 201b makes it easier for the operator to find the correct installation position.
[0045] Specifically, a pull plate 201f is fixed on the mounting block 201c. The pull plate 201f is set to remove the sensor 202. When the sensor 202 needs to be replaced, pulling the pull plate 201f will cause the mounting block 201c to move upward. At this time, the end face of the mounting block 201c will press against the arc end face of the limiting block 201d, thereby compressing the spring 201e. The limiting block 201d moves into the moving groove 201b-2 without affecting the movement of the mounting block 201c. Then the mounting block 201c can be separated from the fixing block 201b to complete the removal of the sensor 202.
[0046] Example 3
[0047] Reference Figures 1-7 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0048] Specifically, the mounting plate 201a has through holes 201a-1. There are multiple through holes 201a-1. The through holes 201a-1 provide a path for the light emitted by the sensor 202, ensuring that the light can be received by the sensor 202 located on the other side of the drawer 103.
[0049] Specifically, an auxiliary plate 201g is fixed on the side plate 103a, and a brush head 201h is provided on the auxiliary plate 201g. Two auxiliary plates 201g are provided on one side plate 103a, distributed on both sides of the light shield 203. The brush head 201h is used to remove dust from the sensor 202. A part of the sensor 202 will be exposed through the through hole 201a-1. The brush head 201h has soft bristles. When the drawer 103 is pulled, the auxiliary plate 201g and the brush head 201h move synchronously. When the brush head 201h passes through the through hole 201a-1, it can remove dust from the exposed part of the sensor 202.
[0050] Specifically, a handle 104 is fixed on the front panel 103b. There are two handles 104. The handles 104 facilitate pulling the drawer 103. A mechanical lock 105 is provided on the handle 104. When the drawer 103 is in the closed state and the back-end system confirms that there is no error, the drawer 103 can be locked by the mechanical lock 105 to prevent the drawer 103 from being opened by accident. This is the prior art. This solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.
[0051] Specifically, a buffer pad 103e is fixed on the back panel 103c. There are multiple buffer pads 103e. When the drawer 103 is closed, the buffer pad 103e can reduce the impact force on the drawer 103, prevent the drawer 103 or cabinet 101 from deforming due to collision, and affect the cooperation between the sensor 202 and the light shield 203. At the same time, it can also reduce the noise generated when the drawer 103 is closed.
[0052] During use, when installing sensor 202, the end face of mounting block 201c will first contact and press against the arc end face of limiting block 201d, thereby compressing spring 201e. Limiting block 201d will move into moving groove 201b-2, thus not hindering the movement of mounting block 201c. As mounting block 201c moves, its end face no longer presses against limiting block 201d. At this time, mounting block 201c fits against slide rail 102. Under the push of spring 201e, limiting block 201d protrudes from the inner wall of slide groove 201b-1, preventing mounting block 201c from separating from slide rail 102.
[0053] When sensor 202 needs to be replaced, pulling the pull plate 201f will cause the mounting block 201c to move upward. At this time, the end face of the mounting block 201c will press against the arc end face of the limiting block 201d, thereby compressing the spring 201e. The limiting block 201d moves into the moving groove 201b-2 without affecting the movement of the mounting block 201c. Then the mounting block 201c can be separated from the fixing block 201b to complete the disassembly of sensor 202.
[0054] Throughout the monitoring process, sensor 202 detects changes in drawer position in real time through light shield 203. Signal processing module and microcontroller process and judge sensor signals, and communication module realizes data transmission with the backend system, thereby realizing the monitoring and backend display functions of real-time drawer opening position of switch cabinet.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
