Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of debugging and control, and particularly relates to a device and method for wireless transmission debugging system. BACKGROUND

[0002] The magnetic flap liquid level meter is a commonly used liquid level measuring instrument, which is widely used in various industrial occasions for continuous measurement of the liquid level of liquid medium. When the liquid level rises, the float rises, the magnet in the float attracts the magnetic material on the flap, causing the flap to turn over, and the red mark faces up, indicating the liquid level height. When the liquid level drops, the flap turns over under the action of its own gravity, and the white mark faces up. The remote transmission type magnetic flap liquid level meter changes the output signal of the sensor through the position change of the float, thereby remotely transmitting the liquid level information.

[0003] The existing magnetic flap liquid level meter is usually wirelessly connected to a remote large screen, and the liquid level value measured by the magnetic flap liquid level meter is transmitted to the large screen through wireless transmission. Relevant personnel can understand the liquid level value from the readings displayed on the large screen. However, in industrial environments, there are many devices such as motors and frequency converters, which may interfere with wireless signals. In addition, other wireless devices (such as devices using wifi or Bluetooth communication methods) in the same frequency band may cause channel competition, causing frequency congestion, thereby interfering with wireless signals, such as the readings displayed on the large screen not updating for a long time. Therefore, before the magnetic flap liquid level meter is put into work, it needs to be debugged, and the readings on the large screen are observed in real time to understand the existing problems in time.

Preferably, the inner side of the limiting plate 24 can be connected with a soft pad, which is in contact with the surface of the magnetic float level meter, which can further avoid the magnetic float level meter from being bumped.

[0032] Further, the driving mechanism 3 comprises a reduction box 37 connected with the fixed frame 22 through the output shaft 21, a driving gear 35 connected with the input shaft of the reduction box 37, and a driving motor 31 connected with the driving gear 35, the driving motor 31 and the reduction box 37 are respectively connected with the supporting mechanism, and the driving gear 35 is used to drive the debugging mechanism 4. In the embodiment, the driving motor 31 is a forward and reverse motor, which is convenient for driving the magnetic float level meter to rotate in two directions. In the embodiment, the driving motor 31 and the reduction box 37 are respectively connected to the supporting mechanism through the support one 32 and the support two 36, the shapes of the support one 32 and the support two 36 are easily thought by those skilled in the art, and can be any shape without affecting the normal work of the driving motor 31 and the reduction box 37, which will not be described in detail here.

[0033] Further, the debugging mechanism 4 comprises a bearing box 42 connected with the supporting mechanism, a bevel gear one 45 connected in the bearing box 42, a bevel gear two 46 engaged with the bevel gear one 45, a driven gear 34 coaxially connected with the bevel gear one 45 through a connecting shaft 43, a lead screw 41 connected with the bevel gear two 46, and the driven gear 34 is connected outside the bearing box 42 and connected with the driving gear 35 through a transmission belt 33. The center part of the bevel gear two 46 is provided with a threaded groove, the lead screw 41 is connected with the bevel gear two 46 through the threaded groove, the two ends of the lead screw 41 respectively pass through the bearing box 42, and one end passes through the through hole 23 and is connected with the float, and a threaded hole is opened in the through hole 23. In the embodiment, the two ends of the bearing box 42 are respectively provided with holes, which is convenient for the movement of the lead screw 41. In the embodiment, the bearing box 42 is provided with a receiving cavity, which can accommodate the bevel gear one 45 and the bevel gear two 46, and the space is limited, so that the bevel gear two 46 can rotate but cannot move axially.

[0034] Further, the supporting mechanism comprises a supporting frame 15 connected with the bearing box 42, a supporting vehicle connected with the supporting frame 15, the supporting frame 15 is arc-shaped and is provided with an arc-shaped opening 17 for the movement of the screw rod 41. In the embodiment, the supporting frame 15 is connected with the supporting vehicle by bolts. Since the connection by bolts is a prior art which can be easily realized by those skilled in the art, no further description is given herein.

[0035] Further, the end of the bearing box 42 is connected with a roller 44, the supporting frame 15 is provided with an arc-shaped groove 16, and the roller 44 is connected in the arc-shaped groove 16. In the embodiment, the roller 44 and the arc-shaped groove 16 are provided with two respectively. The roller 44 can be connected to the bottom of the bearing box 42 by any means. Since the connection mode of the roller 44 belongs to the prior art which can be easily realized by those skilled in the art, no further description is given herein. In the embodiment, a groove is provided in the bottom of the bearing box 42, and the roller 44 is connected in the groove.

[0036] Further, the supporting vehicle comprises a bottom plate 10, a connecting pipe 12 connected with the bottom plate 10, a connecting column 13 connected in the connecting pipe 12, a top plate 14 connected with the connecting column 13, the top plate 14 is connected with the supporting frame 15, a hydraulic cylinder is connected on the bottom plate 10, the output end of the hydraulic cylinder is connected with the top plate 14, and a traveling wheel 11 is connected at the bottom of the connecting pipe 12. Through the above structure, the supporting vehicle can realize the lifting function. When the magnetic flap liquid level meter is in the vertical state, the float height is the lowest, most of the screw rod 41 will be extended from the bearing box 42, so it is necessary to lift the height of the supporting frame 15 by lifting, to avoid the distance between the supporting frame 15 and the ground being too close, so that the screw rod 41 is difficult to extend from the bearing box 42, thereby ensuring the normal work through the above mode.

[0037] The working process of the present application is as follows: First, the bottom flange of the magnetic flap liquid level meter needs to be disassembled, so that the float inside and the external device are connected, then the driving motor 31 is started, the fixed frame 22 is rotated to be close to the horizontal state, then one end of the fixed frame 22 is disassembled, then the magnetic flap liquid level meter is pushed into the fixed frame 22 from this end, at this time the screw rod 41 in the fixed frame 22 will be inserted into the inside of the magnetic flap liquid level meter from the bottom, so that the end of the screw rod 41 contacts with the float, and the screw rod 41 will push the float inside to move to the top end of the magnetic flap liquid level meter, so that the screw rod 41 contacts with the float, after the magnetic flap liquid level meter is put into the fixed frame 22, the part of the fixed frame 22 is assembled, then the limiting plate 24 is connected to the fixed frame 22 by bolts, to avoid the magnetic flap liquid level meter from falling out of the fixed frame 22 during subsequent rotation; Afterwards, the driving motor 31 is started, and the driving motor 31 drives the fixed frame 22 to rotate through the speed reducer 37, and the speed reducer 37 can slow down the rotating speed of the fixed frame 22, so as to facilitate the slow movement of the float, and in the initial state, the fixed frame 22 is in a horizontal state, and the float is located in the magnetic reed liquid level meter, when the driving motor 31 rotates counterclockwise, the fixed frame 22 is driven to rotate counterclockwise through the speed reducer 37, so that the float in the magnetic reed liquid level meter gradually moves downward under the action of gravity; At this time, the driving gear 35 drives the driven gear 34 to rotate through the transmission belt 33, the driven gear 34 drives the bevel gear one 45 to rotate through the connecting shaft 43, and further drives the bevel gear two 46 to rotate, since the through hole 23 at the bottom end of the fixed frame 22 is provided with a thread, when the screw rod 41 is connected in the through hole 23, the height can be kept, and since the center part of the bevel gear two 46 is provided with a thread groove, and the bevel gear two 46 cannot move axially, when the bevel gear two 46 rotates, the screw rod 41 can be driven to rotate, so that the screw rod 41 can move axially, when the driving motor 31 rotates counterclockwise, the screw rod 41 is driven to rotate and move axially outward, so that the screw rod 41 gradually moves downward in the process that the float moves downward, so that the screw rod 41 can always support the float, avoiding that the speed of the float moving downward is too fast, so that the staff can not judge the delay between the liquid level of the magnetic reed liquid level meter and the reading on the large screen; Since the screw rod 41 gradually moves outward in the process that the fixed frame 22 moves from the horizontal direction to the vertical direction, the hydraulic cylinder needs to be started to drive the top plate 14 of the support vehicle to rise, so that the connecting column 13 moves up and down in the connecting pipe 12, thereby driving the support frame 15 to rise, increasing the distance between the support frame 15 and the ground, so as to leave enough space for the screw rod 41; When the fixed frame 22 is in the vertical state and needs to be reset to the horizontal state, the driving motor 31 can be driven to rotate clockwise, so as to drive the fixed frame 22 to rotate and drive the debugging mechanism 4 to rotate, at this time, since the rotating direction of the driving motor 31 is opposite to the previous one, the moving direction of the screw rod 41 changes to move from the outside to the inside, that is, gradually move to the inside of the magnetic reed liquid level meter, so as to drive the screw rod 41 to move the float to the other end, facilitating subsequent debugging, and then the hydraulic cylinder can be used to drive the top plate 14 to descend, facilitating subsequent removal of the magnetic reed liquid level meter, and facilitating the movement of the support vehicle to the device.

[0038] The rollers 44 at the bottom of the bearing box 42 in the embodiment can share a part of the weight and reduce the friction of the bottom surface of the bearing box 42, and the bearing box 42 can be fixed at the bottom of the fixed frame 22, so as to facilitate the movement of the bearing box 42.

[0039] The bottom plate 10 of the support vehicle in the embodiment is connected with a storage battery for supplying power to the driving motor 31, so that the device can be debugged for the magnetic flap liquid level meter at any position in the workshop. The specific connection mode is not shown in the figure. The specific connection line is the prior art that can be easily thought by the person skilled in the art, and will not be described in detail here.

[0040] In the embodiment, the float is driven to move by the motor, and the movement of the float is driven by the bevel gear and the screw rod 41. The float can move slowly in cooperation with the reduction gearbox 37, so as to avoid the fast movement of the float, thereby facilitating the staff to observe the reading problem in time. When the driving motor 31 reversely rotates, the float can move downward under the action of gravity, but the float can only move slowly downward due to the existence of the bevel gear and the screw rod 41, thereby avoiding the fast movement, and the position of the float can be repeatedly moved by combining with the gravity, so as to facilitate the multiple debugging of the magnetic flap liquid level meter. In this process, the staff does not need to manually adjust the position of the float, thereby reducing the fatigue of the staff and ensuring the accuracy of the movement of the float, i.e. the uniform movement at a slow speed, thereby facilitating the staff to observe the reading change in time.

[0041] Moreover, in order to keep the device stable during the movement of the float, the support frame 15 is used to support the fixed frame in the embodiment, and the fixed frame 22 can move stably by the cooperation of the roller 44 and the arc-shaped groove 16. In order to avoid the magnetic flap liquid level meter from falling off from the fixed frame 22 during the movement, the limiting plate 24 is connected with the fixed frame 22 by the bolt in the embodiment, thereby limiting the magnetic flap liquid level meter.

[0042] Since the movement of the float can be realized in the embodiment 1, the embodiment is not for the simple purpose of moving the float, but for the functions of moving the float at a uniform speed, reducing the fatigue of the staff, moving the float without manual operation, keeping the uniform movement at a slow speed when the float moves downward, and the like. In order to better realize the above functions, the embodiment further realizes the functions of avoiding the magnetic flap liquid level meter from falling off, avoiding the contact between the screw rod 41 and the ground to affect the work of the device, keeping the device stable during the work, and the like by other improvements. Therefore, the mechanical structure in the embodiment is not a simple stacking of devices, but considers more and actual existing problems besides moving the float, and improves the problems, and there is a corresponding relationship between the structures. After removing any mechanism, the device is difficult to work and difficult to achieve the technical effects mentioned in the above content.

[0043] Since the above device is used for debugging, after debugging, the wireless transmission mode needs to be optimized for the problem of large screen reading, therefore, the application also provides a wireless transmission debugging system method, based on the above wireless transmission debugging system device, including the following steps: S1, install the magnetic flap liquid level meter after the bottom flange is disassembled into the limiting mechanism 2; S2, rotate the limiting mechanism 2 through the driving mechanism 3; S3, the driving gear 35 in the driving mechanism 3 drives the driven gear 34 to rotate through the transmission belt 33, the bevel gear one 45 connected with the driven gear 34 drives the bevel gear two 46 to rotate, and then drives the lead screw 41 to move; S4, when the magnetic flap liquid level meter is in a vertical state and the float is in the lowest position, the lead screw 41 will push the float to move to the other end under the driving of the driving mechanism 3, and the relevant personnel observe the liquid level of the magnetic flap liquid level meter and the reading of the large screen; S5, when the magnetic flap liquid level meter is in a horizontal state, the driving motor 31 is reversed, the float will move downward due to its own gravity, at this time the lead screw 41 moves reversely, supports the float, and makes the float gradually move downward, and the relevant personnel observe the liquid level of the magnetic flap liquid level meter and the reading of the large screen; S6, when the reading of the large screen has a problem, the wireless transmission mode is adjusted.

[0044] When the reading of the large screen is updated for a long time, the wireless transmission can be optimized in the following way.

[0045] Further, step S6 specifically includes the following steps: S61, a channel capacity improvement model is established, and the total capacity of the sub-channel is calculated; S62, a frequency hopping sequence design model is established, so that the signal jumps between the available sub-channels, and the anti-interference performance is improved; S63, dynamically allocate time slots to reduce the idle time slot resources caused by static allocation.

[0046] For step S61, the following method is used in this embodiment: The channel capacity improvement model is as follows: ; Wherein, represents the bandwidth of the i-th sub-channel; represents the spreading factor of the i-th sub-channel, represents the number of bits carried by each symbol, The larger the anti-noise performance is, for example, SF=7~12 in LoRa; represents the conversion factor of symbol rate and bit rate, symbol rate=bit rate / , represents the maximum interference-free symbol rate of a single subchannel, and N represents the number of subchannels.

[0047] In this way, the capacities of all subchannels can be summed to obtain the total capacity. When a subchannel is strongly interfered, can be increased to reduce the capacity and improve the anti-noise performance, and when a subchannel is weakly interfered, can be reduced to reduce the anti-noise performance and improve the capacity. After adjustment, the total capacity of each subchannel can be calculated by the above model to determine whether the use requirement can be met.

[0048] For step S62, the following method is used in the embodiment: The frequency hopping sequence design model is as follows: ; wherein f(t) represents the carrier frequency at the current time t, f0represents the starting frequency, such as 2.4 GHz of Bluetooth, f represents the frequency interval, such as 1 MHz of Bluetooth, k represents the scaling factor, and controls the frequency hopping range. represents a time-dependent pseudo-random function, which is generated based on LFSR or m sequence, and is used to generate a pseudo-random number.

[0049] In this way, at time t, can be calculated to output a random number, so as to realize pseudo-random frequency modulation, and make jump among available subchannels to realize adaptive frequency hopping, avoid the interfered frequency band, and thus improve the anti-interference performance.

[0050] For step S3, the following method is used in the embodiment: Record historical time series data , wherein represents the data amount of the node at time slot t, such as the number of bytes collected, the number of data packets, etc. Then, an LSTM prediction model is established to learn the traffic time series pattern, such as periodicity and burstiness of data, and output a prediction value. This part is the prior art known to those skilled in the art, and will not be described in detail here. Then, in order to minimize the mean square error, the following objective function is established: ; Through the above training, the prediction value can be made to approximate the true value ​​​​​​​, ensure the reliability of the prediction, when the model predicts that there is no data transmission in the next time slot, then the node is not allocated time slot resources, that is, the timing allocation of the node is skipped, since each node will periodically occupy the time slot, and even when there is no data transmission, the time slot will also be occupied, resulting in idle channel and increased energy consumption, and the present scheme can allocate time slots to nodes with data only according to the prediction result, and idle nodes enter sleep and do not occupy time slots, thereby saving bandwidth and energy.

[0051] In the above manner, the sub-channel capacity or the anti-interference performance of the sub-channel can be selected according to the debugging situation, and it is calculated whether the total capacity of each sub-channel meets the use requirement, and the LSTM model can be used to predict whether the node will have data in the next time slot, and if there is no data, the time slot resource is not allocated to the node, thereby saving energy consumption and bandwidth, and the time slot can be allocated to other nodes that need to transmit data, thereby realizing dynamic allocation of the time slot.

[0052] The above only describes exemplary embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
