In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0032] See also Figures 1 to 16 The present invention provides an aviation wire ground setting device, comprising a test bench 1, a multi-way inching control module 2, a terminal block 3, a moving component 4, a positioning component 5 and a fixed plate 6, wherein the test bench 1 has a plurality of receiving slots 11 for placing wires, and slide slots 12 located on both sides of each receiving slot 11, the multi-way inching control module 2 is arranged on one side of the test bench 1, the number of the terminal blocks 3 is two, the two terminal blocks 3 are arranged on both sides of the test bench 1, and one of the terminal blocks 3 is arranged on the multi-way inching control module 2, and a moving component 4 is arranged above each receiving slot 11;

[0033] Each of the moving components 4 includes two first sliders 41, two vertical rods 42 and a cross bar 43. The two first sliders 41 are arranged in the corresponding slide grooves 12. Each of the first sliders 41 is provided with a vertical rod 42. Both ends of the cross bar 43 are fixedly connected to the two vertical rods 42 respectively. The cross bar 43 has a slide rail 431. Two positioning components 5 are arranged in the slide rail 431. Each of the positioning components 5 includes a second slider 51, a connecting rod 52 and an elastic member 53. The second slider 51 is placed in the slide rail 431. One end of the connecting rod 52 is hinged to the second slider 51, and the other end of the connecting rod 52 is hinged to the fixed plate 6. One end of the elastic member 53 is fixedly connected to the second slider 51, and the other end of the elastic member 53 is fixedly connected to the cross bar 43, and the elastic member 53 is located inside the slide rail 431.

[0034] In this embodiment, the elastic member 53 is a compression spring, and the first slider 41 is slidably connected to the slide slot 12. First, the moving component 4 is slid to one end close to the multi-way inching control module 2, and then the wire to be tested is placed in the accommodating slot 11. At this time, the second slider 51 can be supported by the elastic force of the elastic member 53, and the second slider 51 supports the connecting rod 52, and the connecting rod 52 supports the fixed plate 6. Then, the fixed plate 6 presses the wire placed in the accommodating slot 11, and then one end of the wire is connected to the terminal block 3 on the multi-way inching control module 2. Then, the cross bar 43 is moved toward the end away from the multi-way inching control module 2. As the cross bar 43 moves, the fixed plate 6 moves with The fixed plate 6 straightens the wire, and after the wire is straightened, the other end of the wire is connected to another terminal block 3, and the cycle is repeated. After all the wires to be tested are connected, a multi-way inching control module 2 is used to perform a multi-way inching power-on test to test the performance of the wire. The wires can be straightened to organize the wires, so as to avoid the different shapes of each wire affecting the test comparison results during the test, thereby improving the accuracy of the performance test results of the aviation wire by the ground setting device for the aviation wire, and the cross-section of the accommodating groove 11 is an arc-shaped structure, which can be used together with the positioning component 5 to clamp and fix wires of different diameters, so that the use range of the ground setting device for the aviation wire is wider.

[0035] The multi-channel inching control module 2 is mainly composed of a platform module, a communication module, a command module, an execution module, etc. The design realizes the multi-channel inching control function, the multi-channel cycle control function, the multi-channel simultaneous control function, and the multi-channel variable cycle control function. The development of the system requires the completion of the human-computer interaction interface function box controls called in the process of realizing each control function, the setting of control properties, the layout of the human-computer interaction interface control button page, the writing of the contact address of the control, and the detailed design and implementation of the data flow and the contact on-off relationship when the working condition is given.

[0036] The platform module includes an external box structure. The power supply part provides hardware support and device fixation for the system, and provides 220VAC (external introduction) and 24VDC (AC / DC conversion switch power supply) power output for other modules in the given working condition system, and is supplemented by power distribution devices such as self-protection switch, ammeter and voltmeter. The self-protection switch prevents the circuit from overcurrent and short circuit failure to damage the touch screen and PLC controller. The ammeter and voltmeter measure the current and voltage of the system circuit in real time to monitor the working status of the given working condition system. The communication module is the USB port. The function control software forms an engineering file on the PC side. The upper computer downloads the control software to the touch screen and PLC memory through the communication port to complete the import of the control software. The touch screen and the PLC controller are connected by 232 bus. The PLC controller interface COM1 is connected to the touch screen RS232 interface to transmit digital signals to each other. The command module is a touch screen. The touch screen is used to switch the control function, select the type of aircraft harness signal to be excited, set the given time parameters or start-stop signals through the touch screen channel control control button, and transmit the control command to the PLC programmable logic controller system, and receive the working condition feedback of the PLC controller. The execution module includes a PLC controller and external relays. The PLC controller receives instructions from the human-machine interface system and controls the external relays through the output of the output coil corresponding to the channel after calculation processing. The on-off control of the relay controls the aircraft wiring harness channel. 60 external relays correspond to 60 aircraft wiring harness channels. At the same time, the working condition is fed back to the touch screen of the human-machine interface system by monitoring the status of the output coil.

[0037] The multi-channel jog control function mainly simulates the universal switch to realize the real-time one-to-one on-off control of multiple channels, and displays the channel status in real time to complete the reset of multiple channels. The common components in the function box of the human-computer interaction interface system are called: bit switch, bit indicator light and screen button, etc. The bit switch realizes the on / off state switching and monitoring, and simulates the jog control. Through the attribute setting, different colors can be used to distinguish the 0 / 1 state; the bit indicator light monitors the on / off state of the register value set by the user of the bit switch write address in real time, and dynamically responds to the bit change of the register value. Through the attribute setting, different colors can be used to distinguish the 0 / 1 state; the screen button realizes the switching between different screens, which is suitable for the classification and conversion of different control modes.

[0038] The controls used in the jog function control interface include 60 sets of position switches, 60 sets of position indicators, and reset controls. The on and off position switches and channel position indicators use square icons, and 3 controls implement one channel, for a total of 60 channels. They are distributed in parallel in 6*10 on the interface; the control function switching controls are set at the top of the interface, including 5 screen switching buttons and a reset switch.

[0039] The on and off position switches perform complementary functions, linking a pair of control contacts in the PLC, corresponding to the value of the bit register. When on is set to 1, it is displayed in green, and the contact is connected; when it is set to 0, it is displayed in blue, and the contact is disconnected. When off is set to 0, it is displayed in red, and the contact is connected; when it is set to 1, it is set to green, and the contact is connected; the switch status is displayed through color differences.

[0040] The monitoring address of the bit indicator switch is the PLC output coil, which monitors the working status of the corresponding channel. When the channel output coil is set to 0, the channel is not working and the color is set to yellow. When it is set to 1, the channel is in output state and the channel working color is set to green. When the monitoring address value changes, the color of the bit indicator changes, reflecting the real-time status update of the channel working.

[0041] The position switch corresponds to the controlled contact one by one. Each control channel of the PLC contains a normally open contact, a normally closed contact, a reset contact and a self-locking contact. The on switch write position in the human-machine interaction interface system is the normally open contact, the off switch write position is the normally closed contact, and the reset switch write address is the normally closed contact M1800. The on / off position switch value is written into the memory, and the corresponding contact control state changes.

[0042] Take a control channel as an example. The control of the channel uses a combination of two bit switches and a bit indicator switch. The writing of the on switch corresponds to the normally open contact of M1. The normally open contact of M1 receives the set 1 signal of the on switch, and the normally open contact M1 closes to form a path. The output coil M1001 output signal starts to work. The writing of the off bit indicator switch corresponds to the normally closed contact of M2. The off bit monitoring switch is pressed to set 1. The normally closed contact M2 receives the set 1 signal, and the normally closed contact M2 is disconnected, the path is disconnected, and the output coil M1001 stops working. The working status display is realized by calling the bit indicator switch. The bit indicator switch 01 writes the corresponding address of the output coil M1001, the path is closed, the output coil works and is set to 1. The bit monitoring switch monitors the change of the register value of the output coil M1001. Through the property setting, different colors are displayed for the 0 / 1 state, and the working status of the wire is displayed through color changes.

[0043] The human-machine interface is connected to the setting switch on, press and set it to 1, the on-position switch writes the normally open contact corresponding to the address M1 to 1 to close the path, the control signal is output, and the corresponding output coil M1001 starts working. The off-position switch writes the normally closed contact M2, the off switch is set to 1, the normally closed contact written to the write position M2 is set to 1, the path is disconnected, the control signal is disconnected, and the output coil M1001 stops working. The bit monitoring switch monitors the output coil register value to reflect the corresponding channel value changes.

[0044] In order to meet the multi-channel simultaneous start and stop control function, compared with the multi-channel electric control function, a "total" position switch is set at the front end of all channels. By changing the state of the "total" position switch, the PLC contact is controlled to control all channels. On each branch channel, the position switch is called, and the position is changed by an external signal to complete the channel selection. The position indicator light is called to monitor the output coil register value of the corresponding channel to complete the status display function.

[0045] When setting up the interface of the multi-channel simultaneous control system, the control of a single channel calls a bit monitoring switch and a bit monitoring switch. The bit monitoring switch writes the normally open contact of the corresponding channel in the PLC program, and the bit monitoring switch monitors the output coil of the corresponding channel. The bit monitoring switch is in a rectangular shape, and is edited as the channel number during internal text editing. The bit monitoring switch is in a rectangular shape. When the monitoring register value is 1, it is set to green, and when the monitoring register value is 0, it is set to light blue. The color changes to show the working status of the corresponding channel. The 60 channels are evenly distributed on the interface using a 6X10 matrix.

[0046] The total start and stop switches call position switches respectively. When the start switch is pressed and set to 1, it displays green, and when it is set to 0, it displays red. When the stop switch is pressed and set to 1, it displays orange, and when it is set to 0, it displays red. The color changes reflect the status of the total start and stop switches.

[0047] The human-machine interface control writes the corresponding PLC contact. The external signal changes the PLC contact value through the human-machine interface control, and the contact value changes with the control setting value. The total start and stop position switches are written to the channel front end total normally open contact M400 and total normally closed contact M500 respectively. The channel selection calls the position switch and writes the corresponding channel normally open contacts in turn. When the human-machine interface position switch receives an external signal and changes the setting value, the contact setting value written by it changes. The position indicator is used to monitor the working status of the channel. The monitoring address is the output coil, and the monitoring output coil register value feedback channel status.

[0048] The control and display functions of each channel are realized by a combination of a position switch and a position indicator light, and the multi-channel simultaneous start and stop control functions are realized by using position switches respectively.

[0049] The bit switch write address of the channel 01 selection key is the normally open contact of M1101. When the channel selection key position monitoring switch receives an external signal, the bit switch is set to 1, the bit switch write address is M1101, the normally open contact M1101 is closed, and the channel selection is completed. The start bit monitoring switch receives an external signal and is set to 1, the write position is M400, the normally open contact is set to 1, the normally open contact M400 is closed, the path is formed, and the output coil M1201 starts to output the signal. The stop bit switch receives an external signal and is set to 1, the bit switch write address is M500, the normally closed contact M500 is set to 1, the normally closed contact M500 is disconnected, all channels are cut off, and the output coil stops working. The bit monitoring switch writes the corresponding address of the output coil M1201. When the channel is continuously connected, the output coil M1201 works and is set to 1. The bit monitoring switch monitors that the output coil M1201 is set to 1, and the monitoring switch itself is set to 1. The switch attribute is set to display green when it is set to 1 and light blue when it is set to 0. The channel status is displayed by changing the color. 60 channels are combined in parallel to complete channel control.

[0050] Compared with the previous control function, the multi-channel cycle control function adds the setting of parameters such as the working time and number of cycles of the controlled signal. It is necessary to call the controls such as the numerical input and numerical display of the human-machine interaction interface, and the write address corresponds to the on-delay timer of the PLC channel; each channel sets the corresponding on-delay timer to complete the working time control of the corresponding channel, and calls the numerical display control, whose monitoring address is set to the current value of the timer, to display the cumulative working time of the current working cycle in real time. Call the bit indicator, the monitoring address is the output coil register value, and the corresponding channel status is reflected by the change of the register value. Call the numerical input control, write the address to the preset value of the counter, and complete the setting of the number of cycles. Call the bit switch, the monitoring address is the channel output coil, monitor the change of the output coil register value, call the reset coil, and reset the contacts in the channel after each cycle, ready to start the next cycle.

[0051] The realization of multi-channel cycle control function, each channel group consists of 3 numerical input controls, 3 numerical display controls and 1 bit monitoring switch. The numerical input switch and numerical display control are marked as rectangles, the timing input control is set to blue, and the current value display control is set to green. The timing input and current value display correspond to each other, and a text box is added in the middle to explain the meaning of the displayed value. The status monitoring bit switch is set to a rectangle and placed on the leftmost side of each channel control combination graphic. The control note input is the channel control number. It is set to red when set to 1 and purple when set to 0. The corresponding channel status is reflected by color changes. The start and stop total bit switches are set to rectangles and placed on the leftmost side of the interface. The start switch is set to orange when it is set to 0 and green when it is set to 1. The stop switch is set to red when it is set to 0 and yellow when it is set to 1. The corresponding channel status is reflected by color changes.

[0052] The general start and stop switches are realized by using a normally open contact and a normally closed contact respectively. The start switch is written into the normally open contact and M401, and the stop switch is written into the normally closed contact M501. The contacts are set at the front end of the 60 channels. The on and off of M401 and M501 will directly control the on and off of the 60 sub-channels. The position switch controls the output coil of the corresponding channel. Each group of channels calls 2 on-delay timers to control the on-time and off-time respectively, and calls a counter to record the number of cycles.

[0053] When the control function of a single channel is executed, the address written to the numerical input control NE0000 is D1, which is the preset value of the on-delay timer, the address written to the numerical input control NE0001 is D2 of the on-delay timer, and the address written to the numerical input control NE0002 is the trigger signal of D201. The monitoring address of the numerical display control ND0000 is TV1, which is the current value of the on-delay timer. The monitoring address of ND0001 is TV2, which displays the current value of the off-delay timer, and the monitoring address of the numerical display control N0002 is CV1, which is the current count of the counter. The numerical input control value input is completed. The external signal is input to the position switch, the start position switch is set to 1, the position switch writes the normally open contact with address M401, the normally open contact M401 is set to 1 and closed, the main switch is turned on, the path is formed, the timer receives the signal and starts timing, when the delay timer TV1>D1 is turned on, the normally closed contact T1 is disconnected, the path is disconnected, the delay relay TV2>D2 is turned on, the normally open contact T2 is set to 1 and closed, the counter receives the trigger signal and counts upward in a cycle, and the reset coil T1 starts working, so that the contact T1 is closed, and CV1 is compared with D201. When CV1 is equal to D201, the normally closed contact C1 is disconnected, the channel is disconnected and the output is stopped, 60 channels are controlled in parallel to complete the working condition setting.

[0054] Compared with the previous multi-channel jog and multi-channel simultaneous control functions, the multi-channel variable cycle control adds timing setting and cycle number control, calls the human-computer interaction interface numerical input control, writes the address of the numerical input control to the corresponding channel's connection delay timer, sets the corresponding delay timer for each channel, and completes the timing of the corresponding channel. Call the numerical display control, set its monitoring address to the current value of the timer, and it can display the current cycle's connected time. Call the bit indicator switch, the monitoring address is the output coil register value, and the change of the register value reflects the aircraft harness channel status. Compared with the multi-channel cycle control function, since the cycle is variable, a small cycle is completed by two timings of connection and disconnection, and the timers between cycles work independently. Call the numerical input control, write the address to the preset value of the counter, and complete the cycle number setting. Call the bit monitoring switch, and call the bit monitoring switch for each cycle of the 10-channel confluence channel. The monitoring address is the corresponding channel output coil, and monitors the change of the output coil register value.

[0055] Multi-channel variable cycle control sets 10 channels as a group, and each group can set 5 variable cycles at the same time. Each group contains 10 numeric input controls, and 10 numeric display controls are used to set the timing control parameters. A numeric input control is combined with a numeric display control to realize the setting and display of the number of cycles. The numeric input switch is set to a rectangle, the color is set to blue, the write address is the preset value of each timer, and the display control monitoring address is the current timer value. The numeric display control is set to a rectangle of the same size as the input control, placed correspondingly above and below, and a text box is inserted in the middle to identify the corresponding digital definition. Set the channel start and stop position switch to a rectangle, place it on the left side of the numeric input control, and set the color to 1 when running and set it to 0 when stopping. The status indicator is placed between the number of cycles and the time display control for channel status display. When the channel is connected, the position monitoring switch is set to 1, the color is set to red, and the text in the control is set to on. When the channel is disconnected, the position monitoring switch is set to 0, the color is set to blue, and the text display is set to off. 10 channels are set as a group, and 60 channels are evenly arranged on the interface using 6 horizontal channels.

[0056] Multi-channel variable cycle control: A control unit uses 11 numerical input controls and 11 numerical display controls. The write address of the numerical input control is the preset value of the on-delay timer, and the monitoring address of the numerical display control is the current value of the on-delay relay timing. The write address of the operation start / stop position switch is the normally open contact of M1501, and the write address of the operation status position monitoring switch is M1701. External signals sequentially control the on-delay timers of PLCs with control timing input numbers TV121 - TV130 through the numerical input controls of the human-machine interface to complete the cycle data setting. When the external signal control bit monitoring master switch is set to 1, the normally open contact M1501 is set to 1 and closed, and the channel is connected. Timer TV121 starts timing. When TV121 > D201, the timer stops working, the normally closed contact T121 opens, all channels are disconnected, the normally open contact T121 closes, and the off-timer TV122 starts timing. When TV122 > D202, the off-timer TV122 stops timing, the normally open contact T122 closes, the normally closed contact TV122 opens, and the counter value is incremented by 1. Compare CV61 with the loop preset value D1001. When the value of CV61 is greater than D1001, the loop ends. When CV61 < D1001, the next timer is triggered in sequence. When the T130 timer is triggered, the normally open contact T130 closes, the reset coil is energized, all timers and contacts are reset, and the loop starts working again. Each time the off-timer times, it is judged whether the next off-timing is 0. If so, the counter value is incremented by 1, and the counter value is compared with the preset loop times. When C61 = D1001, the contact C61 opens, all control channels are cut off, and the channel stops working. If the loop times are not set, there is no limit to the loop times, and the harness control is completed manually by disconnecting.
