[0048] The embodiment of the present invention provides a tractor working platform monitoring system, Figure 2 1 is a schematic structural diagram of a tractor working platform monitoring system provided according to an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a work platform provided according to an embodiment of the present invention, with reference to Figure 2 and Figure 3 , the tractor working platform monitoring system includes:

[0049] A working platform 1, a plurality of sensor units 2, an electric device 3 and a control unit 4;

[0050] The working platform 1 includes a fixed plate 11, a track 13 and a plurality of movable plates 12, each movable plate 12 being provided with at least two pulleys 121. The fixed plate 11 is provided on one side of the plurality of movable plates 12, and the fixed plate 11 and the plurality of movable plates 12 are connected end to end in sequence. Adjacent movable plates 12 and the movable plates 12 and the fixed plate 11 can move relative to each other. The fixed plate 11 and the track are fixed to a side of the tractor frame away from the ground. Each movable plate 12 is connected to the track 13 via a pulley 121. The sensor unit 2 is provided on a side of the movable plate 12 close to the tractor frame, and the sensor unit 2 is provided in a one-to-one correspondence with the movable plate 12.

[0051] The pulley 121 is connected to the electric device 3, the control end of the electric device 3 is electrically connected to the first end of the control unit 4, and the multiple sensor units 2 are electrically connected to the second ends of the control unit 4 respectively;

[0052] The sensor unit 2 is used to detect status information of various connection components between the tractor frame and the ground in real time and transmit the status information to the control unit 4; wherein the status information includes at least one of temperature information, vibration frequency information and sound information;

[0053] The control unit 4 is used to determine the area to be inspected based on the status information, and drive the movable plate 12 to move through the electric device 3 to expose the area to be inspected.

[0054] Among them, multiple can be understood as two or more, and the embodiment of the present invention does not limit this. For example, the working platform 1 after the multiple movable plates 12 are fully unfolded can cover the tractor frame. The working platform 1 covering the tractor frame can reduce the fluidity of the fluid at the edge of the frame when the tractor is traveling at high speed, thereby reducing the eddy effect, effectively reducing air resistance, and thus effectively reducing fuel consumption. At least two can be understood as two or more. For example, two or more pulleys 121 can be set on each movable plate 12 according to actual conditions. The sensor unit 2 is set in a one-to-one correspondence with the movable plate 12, which can be understood as a sensor unit 2 is set on each movable plate 12. At least one can be understood as one or more. For example, the status information can include only temperature information, vibration frequency information or sound information, or any two of temperature information, vibration frequency information and sound information, or all of temperature information, vibration frequency information and sound information.

[0055] Specifically, the sensor unit 2 may include at least one of a temperature sensor, a vibration sensor, and a sound sensor. The type of sensor included in the sensor unit 2 can be set according to the status information that needs to be detected, and the embodiment of the present invention does not limit this. Since the working area between the tractor frame and the ground includes a variety of connecting components, the status information of the various connecting components can be detected in real time by the sensor unit 2, and the detected status information is transmitted to the control unit 4, wherein each sensor unit 2 is responsible for detecting the working area corresponding to the sensor unit 2, and the control unit 4 compares the received status information with the preset threshold information. If there is no abnormality in the status information, the multiple mobile plates 12 are controlled by the electric device 3 to maintain the original state to keep the coverage area of ​​the multiple mobile plates 12 on the tractor frame unchanged; if there is an abnormality in the status information, the working area that needs to be inspected is determined according to the position of the sensor unit 2 corresponding to the abnormal status information. At this time, the pulley can be controlled to rotate by the electric device 3, thereby driving the mobile plate 12 to move, so that the position that needs to be inspected is exposed. For example, Figure 3 As shown, taking the working platform 1 including two movable plates 12 as an example, two limit blocks 14 can be set on the top of the middle movable plate 12. When the movable plate 12 is retracted, the two movable plates 12 can be placed overlapping. At this time, the movable plate 12 away from the fixed plate 11 is restricted to the limit blocks 14 close to the fixed plate 11, so as to avoid the two adjacent movable plates 12 from colliding due to excessive movement of the movable plate 12 away from the fixed plate 11; when the movable plate 12 is unfolded, the two movable plates 12 can be spread out and the movable plate 12 away from the fixed plate 11 can be restricted to the limit blocks 14 away from the fixed plate 11, so as to avoid the movable plate 12 away from the fixed plate 11 from moving too fast and leaving the track 13.

[0056] The tractor working platform monitoring system designed in the embodiment of the present invention includes: a working platform 1, multiple sensor units 2, an electric device 3 and a control unit 4, the working platform 1 includes a fixed plate 11, a track 13 and multiple mobile plates 12, each mobile plate 12 is provided with at least two pulleys 121, the fixed plate 11 is set on one side of the multiple mobile plates 12, and the fixed plate 11 and the multiple mobile plates 12 are connected end to end in sequence, adjacent mobile plates 12 and between the mobile plates 12 and the fixed plate 11 can move relative to each other, the fixed plate 11 and the track are fixed to the side of the tractor frame away from the ground, each mobile plate 12 is connected to the track 13 by a pulley 121, the sensor unit 2 is set on the side of the mobile plate 12 close to the tractor frame, and the sensor unit 2 and the mobile plate 12 are connected one by one Corresponding settings are provided, and the pulley 121 is connected to the electric device 3, the control end of the electric device 3 is electrically connected to the first end of the control unit 4, and multiple sensor units 2 are electrically connected to the second end of the control unit 4 respectively. The sensor unit 2 detects the status information of multiple connecting components between the tractor frame and the ground in real time, and transmits the status information to the control unit 4. The control unit 4 determines the area to be inspected according to the status information, and drives the movable plate 12 to move through the electric device 3 to expose the area to be inspected. Compared with the prior art, which requires manual disassembly and installation of the work platform 1 according to maintenance needs, the embodiment of the present invention can automatically control the movement of multiple movable plates 12 according to the status information detected by the sensor unit 2, saving the maintenance time of maintenance personnel and improving work efficiency.

[0057] Furthermore, the control unit is configured to:

[0058] If the status information is abnormal, the movable plate is driven to move by an electric device according to the position of the sensor unit corresponding to the abnormal status information to expose the area to be inspected.

[0059] Specifically, if the status information is abnormal, for example, it may be that at least one of the temperature information, vibration frequency information and sound information is abnormal, then the working area that needs maintenance can be determined based on the position of the sensor unit corresponding to the abnormal status information. At this time, the movable plate can be controlled to move by an electric device to expose the position that needs maintenance to facilitate the staff to carry out maintenance. For example, if the status information detected by the sensor unit set at the movable plate farthest from the fixed plate is abnormal, then only the movable plate farthest from the fixed plate needs to be moved to expose the position that needs maintenance; if the status information detected by the sensor unit set at the movable plate adjacent to the fixed plate is abnormal, then all movable plates need to be moved to expose the position that needs maintenance.

[0060] Further, Figure 3 This is a schematic diagram of another tractor working platform monitoring system provided according to an embodiment of the present invention, referring to Figure 3, the tractor working platform monitoring system includes:

[0061] Alarm device 5; the alarm device 5 is provided in the tractor cab, and the alarm device 5 is connected to the control unit 4;

[0062] The sensor unit includes a temperature sensor 21;

[0063] The temperature sensor 21 is used to detect the temperature information of various connection components between the tractor frame and the ground in real time, and transmit the temperature information to the control unit 4;

[0064] The control unit 4 is used to control the driving state of the tractor and control the alarm device 5 to sound an alarm when the temperature information is abnormal.

[0065] Specifically, if the temperature information is greater than or equal to the first temperature threshold and less than the second temperature threshold, the alarm device 5 is controlled to alarm, and there is no need to change the driving state of the tractor; wherein, the first temperature threshold is less than the second temperature threshold; if the temperature information is greater than or equal to the second temperature threshold, the alarm device 5 is controlled to alarm, and the tractor is forcibly controlled to pull over.

[0066] Furthermore, the control unit is configured to:

[0067] If the temperature information is greater than or equal to a first temperature threshold and less than a second temperature threshold, the alarm device is controlled to sound an alarm; wherein the first temperature threshold is less than the second temperature threshold;

[0068] If the temperature information is greater than or equal to the second temperature threshold, the alarm device is controlled to sound an alarm and the tractor is forcibly controlled to pull over.

[0069] The first temperature threshold and the second temperature threshold can be set according to actual conditions, and the embodiment of the present invention does not limit this.

[0070] Specifically, if the temperature information is greater than or equal to the first temperature threshold and less than the second temperature threshold, it indicates that the various connecting components within the detection area of ​​the sensor unit have a certain high-temperature fire risk. At this time, the alarm device is controlled to sound an alarm to remind the driver that timely maintenance and processing are required; if the temperature information is greater than or equal to the second temperature threshold, it indicates that the various connecting components within the detection area of ​​the sensor unit have a high high-temperature fire risk. At this time, while the alarm device is controlled to sound an alarm, the tractor needs to be forcibly controlled to pull over to ensure driving safety.

[0071] For further reference, Figure 3 , the sensor unit further includes a vibration sensor 22;

[0072] The vibration sensor 22 is used to detect the vibration frequency of various connection components between the tractor frame and the ground in real time and transmit the vibration frequency to the control unit 4;

[0073] The control unit 4 is used to control the driving state of the tractor and control the alarm device 5 to sound an alarm when the vibration frequency is abnormal.

[0074] Specifically, if the vibration frequency is greater than or equal to the first frequency threshold and less than the second frequency threshold, the alarm device 5 is controlled to alarm; wherein, the first frequency threshold is less than the second frequency threshold; if the vibration frequency is greater than or equal to the second frequency threshold, the alarm device 5 is controlled to alarm and the tractor is forcibly controlled to pull over.

[0075] Furthermore, the control unit is configured to:

[0076] If the vibration frequency is greater than or equal to a first frequency threshold and less than a second frequency threshold, the alarm device is controlled to sound an alarm; wherein the first frequency threshold is less than the second frequency threshold;

[0077] If the vibration frequency is greater than or equal to the second frequency threshold, the alarm device is controlled to sound an alarm and the tractor is forcibly controlled to pull over.

[0078] The first frequency threshold and the second frequency threshold can be set according to actual conditions, and the embodiment of the present invention does not limit this.

[0079] Specifically, if the vibration frequency is greater than or equal to the first frequency threshold and less than the second frequency threshold, it means that one / some connecting components in the detection area of ​​the sensor unit are not tightly connected and have a certain risk of failure. At this time, the control alarm device alarms to remind the driver that timely maintenance is required; if the vibration frequency is greater than or equal to the second frequency threshold, it means that one / some connecting components in the detection area of ​​the sensor unit have a high risk of failure. For example, one / some connecting components have a risk of falling off. At this time, while the control alarm device alarms, the tractor needs to be forcibly controlled to pull over to ensure driving safety.

[0080] For further reference, Figure 3 , the sensor unit further includes a sound sensor 23;

[0081] The sound sensor 23 is used to detect the sound information of various connection components between the tractor frame and the ground in real time, and transmit the sound information to the control unit 4;

[0082] The control unit 4 is used to control the driving state of the tractor and control the alarm device 5 to sound an alarm when the sound information is abnormal.

[0083] Specifically, if the sound information is greater than or equal to the first sound decibel threshold and less than the second sound decibel threshold, the alarm device 5 is controlled to alarm; wherein, the first sound decibel threshold is less than the second sound decibel threshold; if the sound information is greater than or equal to the second sound decibel threshold, the alarm device 5 is controlled to alarm and the tractor is forcibly controlled to pull over.

[0084] Furthermore, the control unit is configured to:

[0085] If the sound information is greater than or equal to a first sound decibel threshold and less than a second sound decibel threshold, the alarm device is controlled to sound an alarm; wherein the first sound decibel threshold is less than the second sound decibel threshold;

[0086] If the sound information is greater than or equal to the second sound decibel threshold, the alarm device is controlled to sound an alarm and the tractor is forcibly controlled to pull over.

[0087] The first sound decibel threshold and the second sound decibel threshold can be set according to actual conditions, and the embodiment of the present invention does not limit this.

[0088] Specifically, if the sound information is greater than or equal to the first sound decibel threshold and less than the second sound decibel threshold, it means that one / some connecting components in the detection area of ​​the sensor unit are not tightly connected, and a high sound is likely to occur, and there is a certain risk of failure. At this time, the alarm device is controlled to alarm to remind the driver that timely maintenance is required; if the sound information is greater than or equal to the second sound decibel threshold, it means that one / some connecting components in the detection area of ​​the sensor unit have a high risk of failure. For example, one / some connecting components are broken and there is a risk of falling off. At this time, while the alarm device is controlled to alarm, the tractor needs to be forcibly controlled to pull over to ensure driving safety.

[0092] The control unit 4 is used to control the movement state of the multiple movable plates through the electric device 3 according to the wheel speed information, so as to adjust the coverage area of ​​the multiple movable plates on the tractor frame.

[0093] Specifically, if the wheel speed value detected by the wheel speed sensor 6 is high, it means that the tractor is traveling at a faster speed. At this time, the electric device 3 controls all the movable plates to be unfolded so that the working platform 1 can cover the tractor frame, reducing the fluidity of the fluid at the edge of the frame, thereby reducing the eddy current effect, and effectively reducing the air resistance, thereby effectively reducing fuel consumption.
