Among them, fig. 3(a) and 3(b) constitute an indication circuit.
As shown in fig. 2, the mcu has pins 1 to 40, pin 18 and pin 19 connected to the crystal oscillator circuit, pin 20 grounded, resistor R2 connected to pin 31 and pin 40, switch SW, capacitor C3 and resistor R1 connected in parallel, and common terminal connected to pin 9.
In a specific embodiment, the touch panel to-be-tested part includes a first connector, a second connector and a key, and for easy understanding, the following description will be made in detail with reference to fig. 4(a), 4(b) and 4 (c). As shown in fig. 4(a), 4(b) and 4(c), the touch panel to be tested 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 correspondingly connected with pins P1.4-P1.6 of the micro control unit one by one, pin T1.3 is grounded, pins T2.0-T2.2 of the second connector J2 are correspondingly connected with pins P3.0-P3.2 of the micro control unit one by one, pin T2.4 and pin T2.5 are respectively connected with pin P3.3 and pin P3.4 of the micro control unit, wherein, pins T2.0-T2.2 are all connected with a capacitor, the other end of the capacitor is grounded, and in addition, pin T2.3 is grounded. One end of the key S2 is connected with the pin P3.3 of the micro control unit, the other end is grounded, one end of the key S3 is connected with the pin P3.4 of the micro control unit, and the other end is grounded. When the keys S2 and S3 are activated, i.e., S2 and S3 are closed, the mcu sends detection signals to the keys S2 and S3, and determines whether the returned detection signals satisfy preset conditions, and if so, determines that the keys S2 and S3 are normally activated, and for understanding, the detection key S2 will be used as an example for detailed description. For example, when S2 is closed, the mcu sends a high level to the S2, since the other end of the S2 is grounded, when the high level received by the S2 is pulled low, when the mcu detects that the high level sent to the S23 changes, it can determine that the S2 is valid, and if the high level sent does not change, it determines that the S2 is out of function, and at this time, the mcu controls the indication circuit to be connected to the power supply to alert the inspector that the S2 is out of function. It should be noted that the preset condition is whether the high level is pulled low. It should be noted that, the level value sent to the key S2 or the key S3 by the mcu is not limited in the present invention.
In an embodiment, when the key S2 or the key S3 is activated, i.e., S2 or S3 is closed, the mcu further transmits a detection signal to the first connector J1 and the second connector J2 to detect whether there is conduction between the first connector J1 and the second connector J2. As can be seen from fig. 4(c), one end of the keys S2 and S3 is connected to pin P3.3 and pin P3.4 of the mcu, and as can be seen from fig. 4(b), pin T2.4 and pin T2.5 of the connector J2 are also connected to the mcu via pin P3.3 and pin P3.4. When S2 or S3 is closed, the micro control unit respectively sends a high level signal and a low level signal to any one pin of the first connector J1 and the second connector J2, judges whether the pin receiving the high level is pulled down by the pin receiving the low level, and if the pin receiving the high level is pulled down, the conduction between the detected pins is determined. Also, it should be noted that the level value sent by the mcu is not limited in the present invention, but there is a voltage difference between the levels sent to any one of the pins of the first connector J1 and the second connector J2.
The system for testing the touch pad directly detects the transmission detection signal of the part to the touch pad through the micro control unit, acquires the return signal of the part to be detected by the touch pad, judges whether the return signal meets the preset condition to determine whether the function of the touch pad is normal or not, is simple to operate, can save the time for the traditional tool to wait for the part to be detected by the touch pad to wait for entering the test interface, and improves the test efficiency of the touch pad.
On the basis of the above embodiment, when the key S2 or the key S3 is detected to be abnormal in function, or the first connector J1 and the second connector J2 are not conducted, the micro control unit controls the indicating circuit to be connected with the power supply, so as to inform a tester of the detection result of the part to be detected on the touch panel. As shown in fig. 3(a) and 3(b), the indicating circuit includes a switch S1, an indicator light L1 and an indicator light L2, a buzzer Bell, resistors R3-R6, a power supply and a MOS transistor M1. One end of a switch S1 is connected with a pin P1.0 of the micro control unit, the other end is grounded, an indicator light L1 is connected with an indicator light L2 in parallel, one ends of the indicator light L1 and the indicator light 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 light L1 and the indicator light 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 a resistor R5, the other end of the resistor R5 is connected with a drain electrode of a MOS transistor M1, one end of the resistor R6 is connected with a pin P1.3 of the micro control unit, the other end of the resistor R6 is connected with a gate electrode of a MOS transistor M1, one end of a buzzer Bell is connected with a source electrode of the MOS transistor M1, and the other end of the buzzer is grounded.
When the switch S1 is closed, that is, the mcu receives the signal that the switch S1 is triggered, the mcu transmits a detection signal to the first connector J1 or the second connector J2 to detect whether there is a short circuit between the respective pins of the first connector J1 or the second connector J2. For ease of understanding, the following description will be made in detail by taking the example of detecting the first connector J1. For example, when any one of the keys S2 or S3 is triggered, the mcu transmits a high level and a low level to any two pins T1.0-T1.2 of the pin T1.0-T1.6 of the first connector J1 through the 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 there is a short circuit between the pins of the first connector J1, and at this time, the mcu controls the buzzer Bell to be connected to the power supply, so as to alert the operator that there is a short circuit in the connector. It should be noted that, since the pin T1.3 of the first connector J1 is grounded, when detecting whether a short circuit occurs between the pin T1.3 and any one of the pins T1.0 to T1.2, it is only necessary to send a high level to any one of the pins T1.0 to T1.2. It should be noted that, detection is required to be performed between every two pins of the first connector J1, and it is determined that the first connector functions normally only if there is no short circuit between any two pins.
