Among them, fig. 3 (a) and 3 (b) constitute an instruction circuit.
As shown in fig. 2, the micro-control unit is provided with pins 1-40, pin 18 and pin 19 are connected with the crystal oscillator circuit, pin 20 is grounded, resistor R2 is connected with pin 31 and pin 40 respectively, switch SW, capacitor C3 and resistor R1 are connected in parallel, and the common terminal is connected with pin 9.
In a specific embodiment, the touch pad to-be-tested component includes a first connector, a second connector and keys, and for convenience of understanding, the following will describe in detail with reference to fig. 4 (a), fig. 4 (b) and fig. 4 (c). As shown in fig. 4 (a), 4 (b) and 4 (c), the touch panel to-be-tested part includes a first connector J1, a second connector J2, and left and right keys S2 and S3 of the touch panel. Pins T1.0-T1.2 of the first connector J1 are connected with pins P1.4-P1.6 of the micro control unit in a one-to-one correspondence, pins T1.3 are grounded, pins T2.0-T2.2 of the second connector J2 are connected with pins P3.0-P3.2 of the micro control unit in a one-to-one correspondence, pins T2.4 and pins T2.5 are respectively connected with pins P3.3 and P3.4 of the micro control unit, wherein pins T2.0-T2.2 are connected with a capacitor, the other end of the capacitor is grounded, and in addition, pins T2.3 are grounded. One end of the key S2 is connected with the pin P3.3 of the micro control unit, the other end of the key S3 is grounded, one end of the key S3 is connected with the pin P3.4 of the micro control unit, and the other end of the key S is grounded. When the key S2 and the key S3 are triggered, that is, when the key S2 and the key S3 are closed, the micro control unit sends detection signals to the key S2 and the key S3, and determines whether the returned detection signals meet a preset condition, if so, it is determined that the key S2 and the key S3 are normal and effective, and for convenience of understanding, the detection of the key S2 will be described in detail below as an example. For example, when S2 is closed, the micro control unit sends a high level to the key S2, and since the other ends of the keys S2 are all grounded, when the micro control unit detects that the high level sent to the key S2 3 changes, the micro control unit can determine that the key S2 is normal and valid, and if the sent high level does not change, the micro control unit determines that the key S2 is abnormal, and at this time, the micro control unit controls the indication circuit to be connected with the power supply to alert the detection personnel of the abnormal function of the key S2. It should be noted that the preset condition here is whether the high level is pulled low. In addition, it should be noted that, the present invention is not limited to the level value of the key S2 or the key S3 sent by the micro control unit.
In an embodiment, when the key S2 or the key S3 is activated, that is, when the key S2 or the key S3 is closed, the micro control unit further transmits a detection signal to the first connector J1 and the second connector J2 to detect whether or not the first connector J1 and the second connector J2 are conductive. As can be seen from fig. 4 (c), one end of the key S2 and one end of the key S3 are connected to the pin P3.3 and the pin P3.4 of the micro control unit, and as can be seen from fig. 4 (b), the pin T2.4 and the pin T2.5 of the connector J2 are also connected to the micro control unit through the pin P3.3 and the pin P3.4. When S2 or S3 is closed, the micro control unit sends a high level signal and a low level signal to any one pin of the first connector J1 and the second connector J2 respectively, judges whether the pin receiving the high level is pulled down by the pin receiving the low level, and determines that the detected pins are conducted when the pin receiving the high level is pulled down. Also, it should be noted that the level value transmitted by the micro control unit is not limited in the present invention, but there is a voltage difference between the levels respectively transmitted to any one of the pins of the first connector J1 and the second connector J2.
According to the system for testing the touch panel, the micro control unit is used for directly transmitting the detection signal to the touch panel to-be-detected part, acquiring the return signal of the touch panel to-be-detected part and judging whether the return signal meets the preset condition to determine whether the function of the touch panel is normal or not, the operation is simple, the time that the traditional construction tool needs to wait for entering the test interface for testing the touch panel to-be-detected part can be saved, and the test efficiency of the touch panel is improved.
On the basis of the above embodiment, when the abnormal function of the key S2 or the key S3 or the non-conduction between the first connector J1 and the second connector J2 is detected, the micro control unit controls the indication circuit to be connected with the power supply so as to inform the detection personnel of the detection result of the part to be detected of the touch panel. As shown in fig. 3 (a) and 3 (b), the indication circuit includes a switch S1, an indication lamp L1 and an indication lamp L2, a buzzer Bell, resistors R3-R6, a power supply and a MOS transistor M1. One end of the switch S1 is connected with a pin P1.0 of the micro control unit, the other end of the switch S1 is grounded, the indicator lamp L1 and the indicator lamp L2 are connected in parallel, one ends of the indicator lamp L1 and the indicator lamp L2 are respectively connected with a pin P1.1 and a pin P1.2 of the micro control unit, the other ends of the indicator lamp L1 and the indicator lamp L2 are respectively connected with a resistor R3 and a resistor R4, a common end of the resistor R3 and the resistor R4 is connected with one end of the resistor R5, the other end of the resistor R5 is connected with a drain electrode of the MOS tube M1, one end of the resistor R6 is connected with the pin P1.3 of the micro control unit, the other end of the resistor R6 is connected with a grid electrode of the MOS tube M1, one end of the buzzer Bell is connected with a source electrode of the MOS tube M1, and the other end of the resistor is grounded.
When the switch S1 is closed, that is, the micro control unit receives a signal that the switch S1 is triggered, the micro control unit transmits a detection signal to the first connector J1 or the second connector J2 to detect whether the pins of the first connector J1 or the second connector J2 are shorted. For ease of understanding, the following description will be given in detail with reference to the detection of the first connector J1 as an example. For example, when any one of the keys S2 and S3 is triggered, the micro control unit transmits a high level and a low level to any two pins T1.0-T1.2 of the first connector J1 through pins P1.4-P1.6, and determines whether the pin receiving the high level is pulled down by the pin receiving the low level, if the high level is pulled down, it is determined that a short circuit exists between the pins of the first connector J1, and at this time, the micro control unit controls the buzzer Bell to be connected with the power source to alert the staff that the short circuit exists. It should be noted that, since the pin T1.3 of the first connector J1 is grounded, when detecting whether the pin T1.3 is shorted with any one of the pins T1.0-T1.2, only a high level needs to be sent to any one of the pins T1.0-T1.2. It should be noted that, detection needs to be performed between every two pins of the first connector J1, and no short circuit exists between the two pins to determine that the first connector is normal. In addition, it should be noted that the level values of the connectors of the components to be detected of the touch panel are also transmitted by the micro control unit, and the invention is not limited.
In addition, when the key S2 or the key S3 is activated, that is, the key S2 or the key S3 is closed, the micro control unit transmits a detection signal to the first connector J1 and the second connector J2 to detect whether or not conduction is performed between the first connector J1 and the second connector J2.
