[0002] In the field of inkjet printing technology, different control boards are required to control the movement of different mechanisms for inkjet printing. In order to avoid errors in the coordination of various mechanisms of the printing equipment, it is necessary to control the control boards of various mechanisms to keep the signals, data, and instructions transmitted to each other smoothly. Generally, flexible cables are used to connect the various control boards. The two control boards connected by the flexible cables transmit signals, data, and instructions through the flexible cables to coordinate and control the operations of different mechanisms and ensure the normal printing. In order to achieve data transmission and ensure that the printing can operate normally, it is necessary to set up multiple flexible cable connections between the two control boards. During the connection process, there will be errors in the cable connection, resulting in short circuits or damage to components on the control board.

In order to avoid damage to the components of the control board or affect the printing operation due to abnormal cable connection, it is necessary to promptly feedback abnormal cable wiring.

[0092] When the first connection unit A is connected to the second connection unit B normally, the level signal connected to the gate of the first MOS tube is the first level signal U1 output by the first connection unit A, the first level signal U1 is high level, the drain and source of the first MOS tube are connected, and the second level signal U2 is output; when the first connection unit A is connected to the second connection unit B abnormally, the gate of the first MOS tube is not connected to any level signal, the drain and source of the first MOS tube are disconnected, and the first level signal U1 is output, and the first level signal U1 is high level.

[0093] The second level signal U2 outputted from the output end of the MOS transistor NOT gate circuit 5 indicates that the connection between the corresponding bus wires 4 of the first connection unit A and the second connection unit B is normal. The first level signal U1 outputted from the output end of the MOS transistor NOT gate circuit 5 indicates that the connection between the corresponding bus wires 4 of the first connection unit A and the second connection unit B is abnormal.

[0106] When the level signal connected to the input end of the diode logic unit 6 is the level signal transmitted by the first connection unit A, it is determined that the connection between the first connection unit A and the second connection unit B is normal, otherwise, the connection is abnormal.

[0107] In one embodiment, the first connection unit A connected to the first level and the second level is connected to the second connection unit B, and the second module 2 is provided with a MOS transistor NOT gate circuit 5, and the MOS transistor NOT gate circuit 5 includes:

[0108] A third resistor, a fourth resistor, and a second MOS tube;

[0109] The source of the second MOS tube is connected to the first level signal U1 connected to the second connection unit B through the third resistor; the gate of the second MOS tube is connected to the first level signal U1 output by the first connection unit A through the fourth resistor.

[0110] Specifically, a PIN pin of the first connection unit A is connected to the first level, and the corresponding PIN pin of the second connection unit B connected to the PIN pin is connected to the second level. Similarly, a PIN pin of the first connection unit A is connected to the second level, and the corresponding PIN pin of the second connection unit B connected to the PIN pin is connected to the first level.

[0111] The PIN pin on the first connection unit A is connected to the first level, and outputs the first level signal U1 corresponding to the first level to the second connection unit B through the wiring 4. The gate of the first MOS tube is connected to the high-level first level signal U1, and the source and drain of the first MOS tube are connected to output the second level signal U2.

[0112] The first connection unit A is connected to the first level and the second level, and the corresponding second connection unit B is also connected to the first level and the second level. The interface connected to the first level on the first connection unit A is connected to the interface connected to the second level on the second unit through the cable 4, and the interface connected to the second level on the first connection unit A is connected to the interface connected to the first level on the second unit through the cable 4. The output end of the interface of the first level signal U1 and the second level of the second connection unit B connected to the first connection unit A is connected to the MOS tube NOT gate circuit 5, and a level flip is performed on the first level signal U1 connected through the cable 4, and the first level signal U1 is flipped into the second level signal U2, and further detects whether the first connection unit A and the second connection unit B are connected normally; when the first connection unit A and the second connection unit B are connected through the cable 4 When abnormal, the gate of the first MOS tube has no voltage, the source and the drain are disconnected, and the first level signal U1 is output. The first level signal U1 corresponding to the level signal connected to the diode logic unit 6 is judged to be abnormally connected between the first connection unit A and the second connection unit B, that is, the first level signal U1 connected to the first connection unit A and input to the second connection unit B is anti-collision through the MOS tube NOT gate circuit 5, and the second level signal U2 is output. At the same time, the second level signal U2 input from the first connection unit A to the second connection unit B through the cable 4 is not flipped. When the connection is normal, the second connection unit B outputs the second level signal U2. The diode logic unit 6 outputs a corresponding judgment signal based on whether the level signals input by the input end are all low level. The judgment signal represents that if all are low level, it represents normal, otherwise, it represents abnormal connection.

[0113] Specifically, when the different voltages connected to the same connection unit are the same, and the level signal input to the input end of the diode logic unit 6 is the level signal corresponding to the preset level 3 connected to the first connection unit A, the connection between the first connection unit A and the second connection unit B is normal; if the level signal connected to the diode connection unit includes the level signal of the preset level 3 connected to the second connection unit B, the connection between the first connection unit A and the second connection unit B is abnormal.

[0114] When the preset levels 3 connected to the same connection unit are different, the first connection unit A and the second connection unit B both have PIN pins connected to the first level and PIN pins connected to the second level. The PIN pin of the first connection unit A connected to the first level is connected to the PIN pin of the second unit connected to the second level through the wiring 4, and the first level signal U1 is input to the PIN pin of the second connection. The first level signal U1 is connected to the gate of the first MOS tube in the MOS tube NOT gate circuit 5 through the second connection unit B; the PIN pin of the first connection unit A connected to the second level is connected to the PIN pin of the second connection unit B connected to the first level through the wiring 4, and the first level signal U1 is input to the PIN pin of the second connection.
