Referring to fig. 1-4, the system for detecting program of excavator controller according to the present invention includes a dc power supply 1, a controller 3, an indicator light set 8, a switch set 9 and a potentiometer set 10. The power end of the controller 3 is electrically connected with the direct current power supply 1 to provide 24V direct current for the controller 3.

The digital input end of the controller 3 is electrically connected with one end of the switch group 9, and the other end of the switch group 9 is electrically connected with the anode output end of the direct current power supply 1. The switch group 9 is composed of N switches DIOn. The N switches DIOn are connected to the N digital input pins of the controller 3 one-to-one via 34 core wiring harnesses 4. N is a natural number of 1 or more; n-1. In this embodiment, N is 10. I.e. the switch group 9 consists of 10 switches DIOn. The switch group 9 is used for simulating different control functions in the control program.

Preferably, the switch DIOn is a toggle switch to facilitate operation.

One end of the potentiometer group 10 is electrically connected to the positive output end of the dc power supply 1, the other end of the potentiometer group 10 is electrically connected to the negative output end of the dc power supply 1, and the middle control end of the potentiometer group 10 is electrically connected to the analog input end of the controller 3. The potentiometer set 10 is composed of N multi-turn fine tuning potentiometers ADOn. The N multi-turn precision fine-tuning potentiometers ADOn are correspondingly connected with N analog input pins of the controller one by one through 26 core wire bundles 5. N is a natural number of 1 or more; n is N-1. In this embodiment, N is 10. The potentiometer set 10 is used to simulate an analog input function of an excavator, such as the control handle of the excavator.

The output end of the controller 3 is electrically connected with one end of the indicator lamp set 8, and the other end of the indicator lamp set 8 is electrically connected with the negative electrode output end of the direct current power supply 1. The indicator light set 8 is composed of N indicator lights OUTOn. The N indicator lamps OUTOn are connected with the N output pins of the controller 3 in a one-to-one correspondence manner through the 26-core wire harness 5. N is a natural number of 1 or more; n is N-1. In this embodiment, N is 10. The indicator light group 8 is used to display the logical output of the controller 3.

For example, when testing the "yaw/slew switching" function of the control program of the controller 3, after the power-up of the detection system, the switch DI06 is toggled to be turned on according to the control program. At this time, the indicator light OUT03 will be illuminated. Then, the switch DI06 is turned off, and the indicator light OUTO3 remains lit. Switch DIO2 is then toggled on and indicator light OUTO3 is extinguished. And the reset switch DIO2 and the indicator light OUTO3 are still in the off state, which indicates that the "deflection/rotation switching" function conforms to the logic setting of the control program, and the function is normal.

With regard to other control functions of the controller 3, reference may also be made to the above-described operation of the "yaw/turn-around switching" function, performed in accordance with a control program. And is not at this point cumbersome because of the many other control functions of the controller 3.

The detection system further comprises a detection carriage 6. The indicator light group 8, the switch group 9 and the potentiometer group 10 are all arranged on the detection bracket 6.

Preferably, the surface of the detection support 6 is pasted with identification labels corresponding to the indicator lamp set 8, the switch set 9 and the potentiometer set 10 one by one, so that a worker can correctly operate the switch DIOn or the multi-turn precision fine-tuning potentiometer ADOn and visually read the state of the indicator lamp OUTOn.

Preferably, the detection support 6 is provided with a test harness 7, and the connection ends of the indicator light group 8, the switch group 9, the potentiometer group 10 and the direct-current power supply 1 are electrically connected with the power harness 2 of the direct-current power supply 1 through the test harness 7, so that the connection between the detection support 6 and the direct-current power supply 1 is disconnected, and the detection support is convenient to move.

Further, the test harness 7 extends outward from one end of the detection bracket 6; 26 core pencil 5 and 34 core pencil 4 all outwards extend from the other end that detects support 6, can effectually distinguish the pencil to avoid the pencil to connect wrong problem. Moreover, because the interfaces of the 26 core wire bundles 5 and 34 core wire bundles 4 cannot be used commonly, when the 26 core wire bundles 5 and 34 core wire bundles 4 are connected with the controller 3, the problem of wrong connection of the wire bundles is also avoided, and the safety and reliability of detection are greatly improved.

The detecting bracket 6 of the embodiment mainly comprises a supporting box body with an opening at the upper end and a sealing cover plate. The indicating lamp group 8, the switch group 9 and the potentiometer group 10 are all arranged below the sealing cover plate through bread boards, and the sealing cover plate is arranged at an opening of the supporting box body through bolts.

The operation area is arranged in an inclined plane, and the switch group 9 and the potentiometer group 10 are arranged in the operation area. The indicator lamp group 8, the switch group 9 and the potentiometer group 10 are arranged in a partitioning mode, and devices with different functions in the detection system can be effectively distinguished, so that operation of workers is facilitated.

The working principle of the utility model is as follows: the test harness 7 is connected to the power harness 2 of the dc power supply 1, while the 26-wire harness 5 and 34-wire harness 4 are connected to the respective interfaces of the controller 3. After the connection is finished, the switch of the direct current power supply 1 is turned on, so that the direct current power supply 1 supplies power to the devices on the detection bracket 6 and the controller 3. At this time, the worker only needs to install the control program to test each function of the control program in sequence.
