[0024] Embodiment 1

[0025] Figure 1 A functional module diagram of a portable pantograph detection device provided in an embodiment of the present disclosure, such as Figure 1 As shown, a portable pantograph detection device comprises:

[0026] A test execution unit 101, a test collection unit 102, an industrial computer unit 103 and a human-computer interaction unit 104; wherein the test execution unit 101 controls the start and stop of the pantograph after receiving the test instruction sent by the industrial computer unit 103; the test collection unit 102 collects the pantograph test data of the pantograph after receiving the test instruction sent by the industrial computer unit 103, and sends the pantograph test data to the industrial computer unit 103; the industrial computer unit 103 is used to send instructions to the test execution unit 101 and the test collection unit 102, and calculate the pantograph detection data according to the pantograph test data returned by the test collection unit 102; the human-computer interaction unit 104 is used to call the recording and video equipment of the industrial computer unit 103 to collect the pantograph detection audio and video when the test collection unit 102 receives the test instruction from the industrial computer unit 103.

[0027] Specifically, the test execution unit 101 includes a compressed air pipeline, a pantograph raising cylinder and a solenoid valve. When the solenoid valve is opened, compressed air enters the pantograph raising cylinder, and the compressed air pushes the piston of the pantograph raising cylinder to drive the pantograph to rise and fall.

[0028] Furthermore, the test execution unit 101 controls the connection and disconnection of the optocoupler through the microcontroller IO (Input / Output) interface, controls the connection and disconnection of the intermediate relay through the optocoupler, and then controls the opening and closing of the solenoid valve through the intermediate relay. When the solenoid valve is opened, the compressed air in the compressed air tank enters the bow lifting cylinder, and the compressed air pushes the piston of the bow lifting cylinder to drive the pantograph to rise. When the solenoid valve is closed, the piston of the bow lifting cylinder descends to drive the pantograph to descend.

[0029] Among them, the compressed air tank is a storage tank for storing compressed air, for example, a compressed air storage tank, a gas cylinder, a membrane gas tank and other methods of storing compressed air. The stored compressed air can be transported to the bow lifting cylinder through the compressed air tank, thereby pushing the piston of the bow lifting cylinder.

[0030] Specifically, by controlling the raising and lowering of the pantograph through the test execution unit 101, it is not necessary for multiple people to cooperate to complete the test, which can effectively reduce the labor cost.

[0031] In detail, the test collection unit 102 includes: a wire rope, a reduction motor, a tension sensor, a soft rope, an external proximity switch, and a built-in proximity switch;

[0032] Among them, after receiving the pantograph instruction sent by the industrial computer unit 103, the test execution unit 101 opens the solenoid valve to allow compressed air to enter the pantograph raising cylinder, thereby inflating the pantograph and putting the pantograph in a raised state. The wire rope and the soft rope are used to hook the bow head of the pantograph. At this time, the industrial computer unit 103 sends a test instruction to the test acquisition unit 102, and the human-computer interaction unit 104 starts to call the recording and video equipment of the industrial computer unit 103 to collect the pantograph test audio and video during the pantograph test.

[0033] Specifically, when detecting the tension value and displacement value of the pantograph, the reduction motor in the test acquisition unit 102 is started, and the reduction motor rotates at a constant speed to release the wire rope to pull the pantograph up at a constant speed. The tension value and displacement value of the pantograph when it rises are collected through the tension sensor and sent to the industrial computer unit 103. When the industrial computer unit 103 determines that the tension value is less than the preset minimum tension value, the reduction motor is controlled to stop. After the reduction motor stops for a preset time, that is, a short pause, the reduction motor is controlled to reverse, retract the wire rope, and pull the pantograph down. The tension value and displacement value of the pantograph when it descends are collected through the tension sensor and sent to the industrial computer unit 103. The industrial computer unit 103 can calculate the pressure difference of the pantograph at the same height through the tension value and displacement value of the pantograph when it rises and descends.

[0034] Among them, the same-height pressure difference is the pressure difference caused by the air flow between the pantograph and the overhead line. The same-height pressure difference will affect the contact stability between the pantograph and the overhead line, which may cause poor contact or arcing. The continuous pressure difference will increase the wear of the pantograph and the overhead line. In extreme cases, it will cause the pantograph to detach from the overhead line, affecting the safe operation of the train.

[0035] In detail, when the reduction motor is started and rotates at a constant speed to release the wire rope, and the pantograph is pulled up at a constant speed, the displacement value of the pantograph during the rise is collected by the tension sensor, and the displacement value is transmitted to the industrial computer unit 103. When the industrial computer unit 103 determines that the pantograph has risen to a preset height, the reduction motor is controlled to stop, and the pantograph is suspended at a preset height. The tension value collected by the tension sensor when the pantograph is suspended is used as the static contact pressure of the pantograph.

[0036] Specifically, in the process of detecting the pantograph raising time and lowering time, the pantograph head can be hooked with a soft rope, and the external proximity switch is aligned with the pantograph head and fixed by magnetic attraction. When the test execution unit 101 receives the pantograph raising detection instruction sent by the industrial computer unit 103, the pantograph is controlled to start rising. When the external proximity switch detects that the pantograph head starts to move away, the timing starts until the pantograph head rises to the maximum length of the soft rope. When the built-in proximity switch detects the pantograph head, the timing stops, and the pantograph rising time is obtained.

[0037] Specifically, the detection of the pantograph descending time is the reverse process of the detection of the pantograph rising time. When the test execution unit 101 receives the pantograph lowering detection instruction sent by the industrial computer unit 103, the pantograph is controlled to descend. The timing starts when the built-in proximity switch detects that the pantograph head is moving away, and the timing stops when the external proximity switch detects the pantograph head, thereby obtaining the pantograph descending time.

[0038] Among them, the external proximity switch and the built-in proximity switch are sensors for detecting the approach of an object. Therefore, the distance and approach of the pantograph head can be detected by the external proximity switch and the built-in proximity switch. Specifically, the built-in proximity switch is a switch that directly integrates the sensor inside the device, and is usually directly connected to the control circuit; the external proximity switch can be installed and adjusted independently of the test acquisition unit 102, that is, the external proximity switch can be aligned with the pantograph head and fixed by means of magnetic attraction or the like.

[0039] Specifically, the material of the test collection device can be lightweight materials such as aluminum and plastic, so that the volume and mass of the test collection device are smaller. The test collection device can also include a wire rope drum, a rotary encoder and a control circuit, which are used to wind the wire rope around the wire rope drum; the rotary encoder is a sensor that converts rotational motion into electrical signals, which can measure and monitor the angle, speed and position of the rotating wire rope and soft rope, and is used to determine the speed and position of the pantograph's rise and fall.

[0040] Specifically, the control circuit controls the connection and disconnection of the optical coupler through the IO (Input / Output) interface of the single-chip computer, controls the connection and disconnection of the intermediate relay through the optical coupler, and then the intermediate relay controls the opening and closing of the solenoid valve.

[0041] Exemplarily, the test collection unit 102 may be powered by a lithium-ion battery. The lithium-ion battery has a high energy density and a continuous and stable power supply, and can get rid of the limitation of external power supply and improve the flexibility of the pantograph detection device.

[0042] Specifically, the test collection unit 102 can collect pantograph test data, including the tension value and displacement value when the pantograph is in the raised state, the pantograph raised time and the pantograph lowered time. The test collection unit 102 can communicate through Bluetooth to achieve wireless remote control and wireless transmission of test data between the test collection unit 102 and the industrial flat panel unit, that is, the pantograph detection data can be sent to the industrial computer unit 103 via Bluetooth.

[0043] Exemplarily, Bluetooth communication can be based on Bluetooth Specification V4.0 BLE Bluetooth protocol, the wireless working frequency band is 2.4GHz ISM (Industrial, Scientific, and Medical band), the modulation method is GFSK (Gaussian Frequency-Shift Keying), the maximum transmit power of the module is 4dBm, the receiving sensitivity is -93dBm, and ultra-long-distance communication of 80 meters can be achieved.

[0044] The industrial tablet unit can be a three-proof industrial tablet computer with built-in camera and recording equipment. When the test acquisition unit 102 receives the test instruction, the human-computer interaction unit 104 calls the camera and recording equipment on the industrial tablet unit to realize the audio and video recording of the pantograph detection process, and obtain the pantograph test audio and video.

[0045] Furthermore, the triple-proof industrial tablet computer can be an operating system developed under the ANDROID STUDIO development program. The industrial tablet unit can process the detection data of the pantograph into graphs and audio and video files. For example, the tension value and displacement value when the pantograph rises and falls are plotted into a tension-height curve, and the difference between the tension-height curve when the pantograph descends and the tension-height curve when the pantograph rises can be used to further plot the same-height pressure difference curve of the pantograph; a tension-height bar graph can be drawn through the static contact pressure of the pantograph, and the graph and audio and video files can be automatically saved in the local storage space. The graph and audio and video files can be viewed through the industrial tablet unit, and the graph and audio and video files can be uploaded to the office system corresponding to the pantograph through the HTTP protocol.

[0046] For example, the triple-proof industrial tablet computer can adopt a 7-inch ultra-bright display, an ultra-high-definition display with a high-definition 1920*1200 resolution; 4G ram (Random Access Memory) + 64GEMCP (Embedded Multi-Chip Package) large memory, which can meet the anti-fall requirements, support full Netcom 4G network, support China Unicom, China Mobile, China Telecom 4G Internet access or making and receiving calls, built-in 8500MAH lithium battery, can be used for long-term continuous work, meet the true IP68 triple-proof standard, can achieve high-level waterproof, dustproof, anti-fall, etc., to meet the harsh use environment of various industries, equipped with a hand strap, easy to carry and use, front 5 million + rear 13 million cameras can be called to collect real-time audio and video during pantograph detection.

[0047] Embodiment 2

[0048] Figure 2 The following is a flow chart of a portable pantograph detection method provided by an embodiment of the present disclosure. Figure 2 As shown, a portable pantograph detection method comprises:

[0049] S1. Receive a pantograph inflation instruction sent by an industrial computer unit, and control the pantograph to be in a raised state according to the pantograph inflation instruction.

[0050] In the disclosed embodiment, the industrial computer unit sends a command to the test execution unit to inflate the pantograph so that the pantograph is in a raised state, wherein the test execution unit includes compressed air, a pantograph raising cylinder and a solenoid valve.

[0051] Specifically, the test execution unit controls the connection and disconnection of the optocoupler through the IO (Input / Output) interface of the single-chip computer, controls the connection and disconnection of the intermediate relay through the optocoupler, and then the intermediate relay controls the opening and closing of the solenoid valve. When the solenoid valve is opened, compressed air enters the bow lifting cylinder, and the compressed air pushes the piston of the bow lifting cylinder to drive the pantograph to rise. When the solenoid valve is closed, the piston of the bow lifting cylinder descends, driving the pantograph to descend.

[0052] S2. Using a test collection unit to collect the tension value and displacement value of the pantograph when it is in a raised state.

[0053] In the disclosed embodiment, the pantograph raising state includes the state when the test execution unit controls the pantograph to rise and fall, and the tension value and displacement value include the rising tension value and the rising displacement value when the pantograph is raised, and the falling tension value and the falling displacement value when the pantograph is lowered.

[0054] In the embodiment of the present disclosure, the use of a test collection unit to collect the tension value and the displacement value of the pantograph when the pantograph is in a raised state includes:

[0055] When the pantograph rises at a uniform speed, the tension sensor in the test collection unit is used to collect the rising tension value and the rising displacement value of the pantograph;

[0056] When the rising tension value is less than a preset minimum tension value, the pantograph is controlled to descend, and the descending tension value and the descending displacement value of the pantograph are collected by using the tension sensor;

[0057] When the rising height of the pantograph meets a preset threshold, collecting a height tension value of the pantograph;

[0058] The rising tension value, the rising displacement value, the falling tension value, the falling displacement value and the height tension value are collected to obtain the tension value and the displacement value when the pantograph is in the raised state.

[0059] Specifically, the test collection unit includes: a wire rope, a reduction motor, a tension sensor, a soft rope, an external proximity switch, and a built-in proximity switch. The reduction motor in the test collection unit rotates at a constant speed to release the wire rope and pull the pantograph to rise at a constant speed. The tension value and displacement value of the pantograph when rising are collected by the tension sensor and sent to the industrial computer unit. When the industrial computer unit determines that the tension value is less than the preset minimum tension value, the reduction motor is controlled to stop to obtain the tension value and displacement value of the pantograph when rising; when the industrial computer unit determines that the tension value is less than the preset minimum tension value, the reduction motor is controlled to stop. After the reduction motor stops for a preset time, that is, a short pause, the reduction motor is controlled to reverse, retract the wire rope, and pull the pantograph down. The tension value and displacement value of the pantograph when descending are collected by the tension sensor.

[0060] In the disclosed embodiment, the tension value and displacement value of the pantograph can be plotted by an industrial computer unit with the tension value as the horizontal axis and the displacement value as the vertical axis. Therefore, the tension-height curve when the pantograph is raised and the tension-height curve when the pantograph is lowered can be obtained.

[0061] S3. Calculate the pressure difference at the same height and the static contact pressure of the pantograph according to the tension value and the displacement value.

[0062] In the disclosed embodiment, the pressure difference at the same height is the difference between the contact pressures when the pantograph is in contact with the overhead line and the heights of the pantograph and the overhead line are the same. The static contact pressure is the pantograph pressure collected by the tension sensor when the pantograph rises to a preset height and the pantograph is hovering.

[0063] Further, the calculating the pressure difference at the same height and the static contact pressure of the pantograph according to the tension value and the displacement value includes:

[0064] Constructing a tension-height curve according to the tension value and the displacement value;

[0065] Calculating the pressure difference at the same height of the pantograph according to the tension-height curve;

[0066] The height tension value among the tension values ​​is used as the static contact pressure of the pantograph.

[0067] The tension-height curve includes an ascending tension-height curve when the pantograph is ascending and a descending tension-height curve when the pantograph is descending, and the curve difference between the ascending tension-height curve and the descending tension-height curve is calculated to calculate the pressure difference at the same height of the pantograph;

[0068] Specifically, constructing a tension-height curve according to the tension value and the displacement value includes:

[0069] Draw and generate a rising tension-height curve according to the rising tension value and the rising displacement value in the tension value and the displacement value;

[0070] Draw and generate a descending tension-height curve according to the descending tension value and the descending displacement value in the tension value and the displacement value;

[0071] The ascending tension-height curve and the descending tension-height curve are collected to obtain a tension-height curve.

[0072] Specifically, the tension value and displacement value when the pantograph rises and falls are plotted into a tension-height curve, and the pressure difference at the same height of the pantograph is obtained by the tension difference corresponding to the same displacement value between the tension-height curve when the pantograph falls and the tension-height curve when the pantograph rises.

[0073] Specifically, the tension value includes the tension value collected by the tension sensor when the pantograph's rising height meets a preset threshold, that is, when the industrial flat panel unit raises the pantograph to a specified height, the motor stops and the pantograph hovers at a certain height. The tension value collected at this time is the static contact pressure of the pantograph.

[0074] S4. Use the test acquisition unit to control the pantograph to raise to a preset raising position and collect the raising time, and control the pantograph to lower from the raising position to a preset lowering position and collect the lowering time.

[0075] In the disclosed embodiment, the soft rope in the test collection unit can hook the bow head of the pantograph, and the external proximity switch is aligned with the bow head of the pantograph and fixed by magnetic attraction. When the test execution unit receives the bow raising detection instruction sent by the industrial computer unit, the pantograph is controlled to start rising. When the external proximity switch detects that the bow head of the pantograph starts to move away, the timing starts until the bow head of the pantograph rises to the maximum length of the soft rope. The timing stops when the built-in proximity switch detects the bow head of the pantograph, and the pantograph rising time is obtained.

[0076] In the disclosed embodiment, the detection of the pantograph descending time is the reverse process of the detection of the pantograph rising time. When the test execution unit receives the pantograph lowering detection instruction sent by the industrial computer unit, the pantograph is controlled to descend. The timing starts when the built-in proximity switch detects that the pantograph head is moving away, and the timing stops when the external proximity switch detects the pantograph head, thereby obtaining the pantograph descending time.

[0077] S5. Collect the pressure difference at the same height, the static contact pressure, the pantograph raising time and the pantograph lowering time to obtain pantograph detection data of the pantograph.

[0078] Specifically, the pantograph detection data includes the pantograph's pressure difference at the same height, static contact pressure, pantograph raising time, and pantograph lowering time. The pantograph detection data can ensure the real-time and accuracy of pantograph detection, thereby improving the accuracy and efficiency of pantograph detection.

[0079] Embodiment 3

[0080] On the basis of the above embodiments, in order to more clearly understand the present disclosure, the method for performing pantograph static contact pressure detection more quickly in Embodiment 1 of the present disclosure is further explained through a third embodiment below, including:

[0081] The force measuring device is moved to the pantograph by a mechanical arm, and the pantograph is started so that the pantograph and the pressure rod of the force measuring device are pressed against each other, and the pressure generated by the pantograph on the pressure rod is transmitted to the pressure sensor, so that the pressure sensor can measure the value of the pressure generated by the pantograph on the pressure rod; and the pressure sensor sends the measured pressure value to the industrial computer unit through the wireless transmission module, and displays it on the display screen of the industrial computer unit.

[0082] Among them, the pressure sensor can measure the value of the pressure generated by the pantograph on the pressure rod. The pressure rod may include a contact rod and a rubber pad. The pantograph can be embedded in the groove of the rubber pad. The pressure generated by the pantograph on the rubber pad is transmitted to the contact rod, and the contact rod then transmits the pressure to the pressure sensor to obtain the static contact pressure of the pantograph.
