Description

Technical Field

[0001] This application relates to the field of sensor calibration technology, and more specifically, to a heating stage for calibrating a suspension gap sensor. Background Technology

[0002] The suspension gap sensor is installed in the electromagnet module. The electromagnet coil is often made of aluminum foil. Due to the high current density of the coil under normal operating conditions, the electromagnet generates a lot of heat. When the vehicle is levitating or running, especially when the vehicle is stationary or running at low speed, the temperature of the electromagnet rises rapidly. The heat generated by the electromagnet will be quickly transferred to the detection coil and processing circuit of the suspension gap sensor, with the highest temperature reaching 85°C. This makes the output signal of the suspension gap sensor prone to large temperature drift. In the production process, a method of directional heating of the suspension gap sensor is used to calibrate the output signal of the suspension gap sensor, which can reduce the negative impact of high temperature on the suspension gap sensor. However, there is a lack of a device for directional heating of the suspension gap sensor.

[0003] In summary, how to achieve directional heating of the suspension gap sensor is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] The core of this application is to provide a heating stage for calibrating a suspension gap sensor, which can achieve directional heating of the suspension gap sensor.

[0049] This application provides a heating stage for calibrating a suspension gap sensor, used for directional heating of the suspension gap sensor. The heating stage for calibrating the suspension gap sensor includes a frame 1, a heating fixture 2, and a heating assembly 3. The heating fixture 2 is disposed on the worktable of the frame 1 and has a receiving groove for receiving the suspension gap sensor. The heating assembly 3 is disposed on the heating fixture 2 and located at the bottom of the receiving groove for contacting and heating the coil heating surface at the bottom of the suspension gap sensor.

[0050] refer to Figures 1 to 4 As explained, the frame 1 is used to install and support the heating fixture 2 and the heating assembly 3. It can be a tabletop or benchtop base, etc. The heating fixture 2 is installed above the top worktable of the frame 1. To position the suspended gap sensor to be heated, a receiving groove is provided in the middle of the top of the heating fixture 2 to hold the suspended gap sensor. Correspondingly, the heating assembly 3 is installed on the heating fixture 2 to heat the suspended gap sensor. To achieve directional heating of the suspended gap sensor, the heating assembly 3 is located at the bottom of the receiving groove, and the heating surface of the heating assembly 3... Located directly above, so as to contact the coil heating surface of the suspension gap sensor, when the suspension gap sensor is placed in the receiving groove with its own coil heating surface directly below, the bottom coil heating surface of the suspension gap sensor contacts the top heating surface of the heating component 3. In other words, the top heating surface of the heating component 3 contacts the coil side at the bottom of the suspension gap sensor, thereby activating the heating component 3. This enables directional heating of the coil of the suspension gap sensor, while avoiding damage to the main control board of the suspension gap sensor during the heating process, thus reducing calibration risk.

[0051] Based on the above embodiments, it also includes a temperature sensor 4, a temperature control module 5, and a cooling fan 6;

[0052] Temperature sensor 4 is used to detect the temperature of the suspension gap sensor;

[0053] Cooling fan 6 is used to remove heat from the suspension gap sensor;

[0054] The temperature control module 5 is connected to the temperature sensor 4, the heating component 3, and the cooling fan 6. It is used to receive the detection results of the temperature sensor 4 and control the start and stop of the heating component 3 and the cooling fan 6 so as to control the target temperature of the suspension gap sensor.

[0055] refer to Figures 5 to 8 As explained, in order to adjust the heating temperature of the coil in the suspension gap sensor, a temperature sensor 4, a temperature control module 5, and a cooling fan 6 are provided. The heating component 3, the temperature sensor 4, the temperature control module 5, and the cooling fan 6 are all installed on the heating fixture 2.

[0056] Among them, the temperature sensor 4 is located at the top or bottom of the receiving groove, which can test the temperature of the suspended gap sensor placed in the receiving groove and transmit the tested temperature data to the temperature control module 5.

[0057] The cooling fan 6 is located on the side of the receiving groove to blow air onto the floating gap sensor placed in the receiving groove, thereby carrying away the heat on the floating gap sensor and cooling it down.

[0058] The temperature control module 5 compares the received temperature data with the target temperature, and then controls the heating component 3 to start when the suspension gap sensor needs to be heated, and conversely, controls the cooling fan 6 to start when the suspension gap sensor needs to be cooled.

[0059] Based on the above embodiments, the number of heating fixtures 2 is greater than or equal to two, and a plurality of heating fixtures 2 are arranged sequentially along the length of the frame 1.

[0060] Several heating fixtures 2 are equipped with corresponding heating components 3, temperature control modules 5, temperature sensors 4, and cooling fans 6.

[0061] refer to Figures 1 to 4 To improve the efficiency of directional heating for calibration of the suspension gap sensor, several heating fixtures 2 are set on the worktable above the frame 1. The heating fixtures 2 are arranged in rows along the length of the frame 1. It should be noted that there is no limit to the number of rows of heating fixtures 2, such as two rows or four rows. Each heating fixture 2 is equipped with a heating component 3, a temperature control module 5, a temperature sensor 4, and a cooling fan 6, so as to heat, test the temperature, and cool the suspension gap sensor placed on each heating fixture 2.

[0062] Based on the above embodiments, the frame 1 includes a support frame 11, a first mounting plate 12, and a second mounting plate 13;

[0063] The first mounting plate 12 and the second mounting plate 13 extend laterally, and the first mounting plate 12 and the second mounting plate 13 are arranged side by side vertically.

[0064] Several heating fixtures 2 are disposed on the first mounting plate 12 and arranged sequentially along the length of the frame 1;

[0065] Several heating fixtures 2 are mounted on the second mounting plate 13 and arranged sequentially along the length of the frame 1.

[0066] refer to Figures 1 to 4 As explained, in the bracket, the support frame 11 connects and supports several components equipped with the calibration heating table. A first mounting plate 12 and a second mounting plate 13 are arranged above the support frame 11. Both the first mounting plate 12 and the second mounting plate 13 extend laterally and are arranged side by side vertically. Thus, the bracket has two worktables as described above. Of all the heating fixtures 2 equipped with the calibration heating table, some heating fixtures 2 are installed on the first mounting plate 12, and the remaining heating fixtures 2 are installed on the second mounting plate 13. It should be noted that the number and layout of the heating fixtures 2 on the first mounting plate 12 and the heating fixtures 2 on the second mounting plate 13 are not limited. The bracket can meet the installation requirements of several heating fixtures 2, and the frame 1 is lightweight and easy to transport.

[0067] In some embodiments, the number of heating fixtures 2 provided on the first mounting plate 12 is equal to the number of heating fixtures 2 provided on the second mounting plate 13. For example, the number of heating fixtures 2 is ten. Five heating fixtures 2 are arranged on the upper first mounting plate 12 along the length of the frame, and five heating fixtures 2 are also arranged on the lower second mounting plate 13 along the length of the frame. The heating fixtures 2 provided on the first mounting plate 12 and the corresponding heating fixtures 2 provided on the second mounting plate 13 are arranged in a vertical row.

[0068] Based on the above embodiments, the rack 1 is also provided with electrical control components;

[0069] The support frame 11 includes three rectangular support frames 111 and four support rods 112. The support rods 112 extend vertically and the four support rods 112 are arranged in a rectangular shape. The three rectangular support frames 111 are all located in the middle of the four support rods 112 and the three rectangular support frames 111 are arranged at intervals vertically.

[0070] The first mounting plate 12 is located on the top of the top rectangular support frame 111, the second mounting plate 13 is located on the top of the middle rectangular support frame 111, and the electrical control components are located on the top of the bottom rectangular support frame 111.

[0071] refer to Figure 1 As explained, to meet the operational requirements of heating component 3, temperature sensor 4, temperature control module 5, and cooling fan 6, electrical control components are installed below the workbench of frame 1, for example, in... Figure 1Inside the control box shown, preferably, the electrical control components are supplied with a voltage range of 198V to 242V and a frequency of 50Hz.

[0072] In the support frame 11, four support rods 112 extend vertically and are arranged in a rectangular pattern, that is, they are arranged at the four apex positions of the rectangular area. The rectangular support frame 111 is connected to the four support rods 112, and the four apex positions of the rectangular support frame 111 are connected to the corresponding support rods 112. The three rectangular support frames 111 are arranged alternately from top to bottom. The electrical control components are installed in the bottom rectangular support frame 111 through a control box or board, while the first mounting plate 12 is installed in the top rectangular support tube, and the second mounting plate 13 is installed in the middle rectangular support frame 111. With this arrangement, the layout of the calibration heating table is reasonable, the overall structure is strong, the load-bearing capacity is strong, and the weight is light.

[0073] Based on the above embodiments, the heating fixture 2 includes a support plate 21 and an h-shaped mounting frame 22, with the bottom open end of the mounting frame 22 connected to the support plate 21.

[0074] The receiving groove is located at the top of the top plate of the mounting frame 22, the heating component 3 is disposed on the top plate of the mounting frame 22, and the cooling fan 6 is disposed on the top of the long plate of the mounting frame 22 and located at the top of the top plate of the mounting frame 22.

[0075] Temperature sensor 4 is disposed on support plate 21. Temperature sensor 4 is located in the bottom inner cavity of mounting frame 22 and is located directly below receiving groove.

[0076] Temperature control module 5 is installed on the short plate of mounting frame 22.

[0077] refer to Figure 5 and Figure 6 As explained, the edge of the support plate 21 protrudes to the outside of the mounting frame 22, and can be installed on the bracket by fasteners. The mounting frame 22 adopts an H-shaped frame structure, in which the short plate is located on the left and extends vertically, with its bottom end connected to the lower mounting plate; the long plate is located on the right and extends vertically, with its bottom end connected to the lower mounting plate; and the top plate of the mounting frame 22 extends horizontally, with its left end connected to the top of the left short plate and its right end connected to the middle of the height of the right long plate. To meet the heating requirements, the top plate of the mounting frame 22 is a high-temperature heat conductor plate.

[0078] Correspondingly, a receiving groove is formed on the top of the top plate of the mounting frame 22. Preferably, the receiving groove is a contour groove of the suspension gap sensor, which can fit into the suspension gap sensor.

[0079] To meet the installation and operation requirements of the cooling fan 6, the long plate has a ventilation channel in its own thickness direction, that is, the ventilation channel extends laterally and is located at the top of the receiving groove. The cooling fan 6 is installed on the long plate of the mounting frame 22 and is directly opposite the ventilation channel, so the cooling fan 6 can continuously blow cooling air towards one side of the receiving groove.

[0080] Temperature sensor 4 is mounted on the mounting plate via a bracket, and the temperature sensor 4 is mounted on the top of the bracket extending into the receiving groove, so as to be positioned directly below the receiving groove.

[0081] The temperature control module 5 is installed on the left short plate of the mounting frame 22. Preferably, the temperature control module 5 adopts a control panel, such as including a display screen and / or input keyboard, which can display and / or input the control parameters of the heating component 3.

[0082] exist Figures 5 to 8 In the embodiment of the heating fixture 2 shown, the height H0 of the heating fixture 2 is 375mm, the length L0 is 400mm, and the width W0 is 260mm; correspondingly, as Figures 1 to 4 As shown, the height H1 of bracket 1 is 1120mm, the length L1 is 1800mm, and the width W1 is 700mm. The total height H of the calibration heating table equipped with the heating fixture of the above dimensions is 1495mm. Of course, the dimensions of the calibration heating table are not limited to the example type above, as long as they meet the installation and support requirements of each component.

[0083] Based on the above embodiments, the target temperature range is 30°C to 250°C. This embodiment provides that the temperature control module 5 can be selectively set to control the target temperature range when the heating component 3 is working.

[0084] To ensure the accuracy of heating the suspension gap sensor, based on the above embodiment, the temperature control module 5 is used to control the heating component 3 to stop when the detection result of the temperature sensor 4 is equal to the difference between the target temperature and the hysteresis temperature; and to control the cooling fan 6 to stop when the detection result of the temperature sensor 4 is equal to the sum of the target temperature and the hysteresis temperature.

[0085] In this embodiment, a hysteresis temperature is set in the temperature control module 5 to deal with the lag phenomenon in the heating process of the suspension gap sensor.

[0086] Specifically, when the temperature of the suspension gap sensor is less than the difference between the target temperature and the hysteresis temperature, the heating component 3 is activated to raise the temperature. During the temperature rise of the suspension gap sensor, the temperature sensor 4 continuously monitors the temperature. When the temperature data detected by the temperature sensor 4 equals the difference between the target temperature and the hysteresis temperature, the heating component 3 is deactivated to maintain the suspension gap sensor at the target temperature.

[0087] Similarly, when the temperature of the suspension gap sensor is greater than the sum of the target temperature and the hysteresis temperature, the cooling fan 6 is controlled to work to achieve cooling. During the cooling process of the suspension gap sensor, the temperature sensor 4 is controlled to continuously monitor. When the temperature data detected by the temperature sensor 4 is equal to the sum of the target temperature and the hysteresis temperature, the cooling fan 6 is controlled to stop working in order to keep the suspension gap sensor at the target temperature.

[0088] In summary, in this embodiment, the temperature control module 5, heating component 3, and cooling fan 6 work together to heat the suspension gap sensor at a constant temperature, which helps to improve the measurement accuracy of the suspension gap sensor.

[0089] To achieve the above control functions, based on the above embodiments, and to ensure the heating accuracy of the suspension gap sensor, the temperature control module 5 includes a temperature input device and a processor. The temperature input device is used to input the target temperature and the hysteresis temperature. The processor is connected to the temperature input device to receive the target temperature and the hysteresis temperature, and to control the heating component 3 to stop when it rises to near the target temperature, or to control the cooling fan 6 to stop when it falls to near the target temperature.

[0090] In this embodiment, a hysteresis temperature is set in the temperature control module 5 to deal with the lag phenomenon in the heating process of the suspension gap sensor. The temperature input device can be a keyboard or a touch screen, etc. When in use, the temperature input device is used to set the target temperature and hysteresis temperature for the processor. Then, the processor controls whether the heating component 3 and the cooling fan 6 work according to the preset control logic and the obtained target temperature and hysteresis temperature.

[0091] In some specific embodiments, the hysteresis temperature is a range including the target temperature. The processor receives the target temperature and the hysteresis temperature and controls the heating component 3 to stop when the detection result of the temperature sensor 4 rises to a minimum threshold equal to the hysteresis temperature, or when the detection result of the temperature sensor 4 falls to a maximum threshold equal to the hysteresis temperature. That is, the processor needs to compare the received detection result of the temperature sensor 4 with the maximum or minimum threshold of the hysteresis temperature and control the start and stop of the heating component 3 and the temperature sensor 4. It should be noted that in this embodiment, the difference between the maximum threshold of the hysteresis temperature and the target temperature, and the difference between the target temperature and the minimum threshold of the hysteresis temperature, may or may not be equal.

[0092] In some specific embodiments, both the target temperature and the hysteresis temperature are accurate values. The processor receives the target temperature and the hysteresis temperature and controls the heating component 3 to stop when the detection result of the temperature sensor 4 rises to the difference between the target temperature and the hysteresis temperature, or controls the cooling fan 6 to stop when the detection result of the temperature sensor 4 drops to the difference between the target temperature and the hysteresis temperature. Specifically, the processor needs to calculate the difference or sum of the target temperature and the hysteresis temperature, i.e., determine the maximum temperature threshold and the minimum temperature threshold, and compare the detection result of the temperature sensor 4 with the data processed by the processor to send a control signal to the heating component 3 or the cooling fan 6. During the heating phase, when the detection result of the temperature sensor 4 is less than the minimum temperature threshold, the heating component 3 is controlled to continue working, and when the detection result of the temperature sensor 4 is equal to the minimum temperature threshold, the heating component is controlled to stop. Similarly, during the cooling phase, when the detection result of the temperature sensor 4 is greater than the maximum temperature threshold, the cooling fan 6 is controlled to continue working, and when the detection result of the temperature sensor 4 is equal to the maximum temperature threshold, the cooling fan 6 is controlled to stop.

[0093] Based on the above embodiments, the temperature control module 5 includes a controller, a relay module one, and a relay drive module two;

[0094] The relay module is electrically connected to the heating assembly 3;

[0095] The relay module 2 is electrically connected to the cooling fan 6;

[0096] The controller is electrically connected to relay module 1, relay module 2, and temperature sensor 4. It is used to receive the detection results of temperature sensor 4 and control the opening and closing of relay module 1 and relay module 2.

[0097] When in use, after receiving the detection result from the temperature sensor 4, the controller can compare it with the target temperature to determine whether heating or cooling is needed next. Then, it selects to activate either the control relay module one or the relay module two, so that the power supply line of the heating component 3 or the cooling fan 6 is switched on or off. The temperature control module 5 can then perform closed-loop control to dynamically, accurately and quickly adjust the temperature of the calibrated heating platform.

[0098] Based on the above embodiment, the frame 1 is also provided with a warning indicator light 7, which is connected to the temperature control module 5 and is used to indicate the working status of the heating component 3.

[0099] refer to Figure 1 and Figure 2As explained, a mounting platform is provided on the outside of the frame 1, and the warning indicator light 7 is installed above the mounting platform. When in use, while the heating component 3 heats the suspension gap sensor, the temperature control module 5 controls the warning indicator light 7 to light up the target color, thereby indicating whether the heating component 3 is in the heating state.

[0100] It should be noted that the number of warning indicator lights 7 is not limited, as long as it meets the requirements for indicating the working status of the heating component 3. Preferably, the number of warning indicator lights 7 is equal to the number of heating fixtures 2. Several warning indicator lights 7 are connected to the corresponding temperature control modules 5. Since several temperature control modules 5 are connected to the heating components 3 set in the corresponding heating fixtures 2, the warning indicator lights 7 can indicate the working status of the heating components 3 set in the corresponding fixtures. For example, a green light is lit when working normally and a yellow light is lit when not working normally, or a red light is lit when working normally and a white light is lit when not working normally, etc.
