Further, fig. 3 shows a circuit configuration of the charging device shown in fig. 2, and for convenience of explanation, only a portion related to the embodiment of the present invention is shown, and the following details are given:
the timing unit 110 is a 555 timer, and the switching unit 111 is a transistor Q. The low trigger pin 2 of the 555 timer is the first input end of the timing unit 110, the high trigger pin 6 of the 555 timer is the second input end of the timing unit 110, the power pin 8 of the 555 timer is the third input end of the timing unit 110, the reset pin 4 of the 555 timer is the reset end of the timing unit 110, the control input pin 5 of the 555 timer is the fourth input end of the timing unit 110, the output pin 3 of the 555 timer is the output end of the timing unit 110, the grid electrode of the transistor Q is the control end of the switch unit 111, the drain electrode of the transistor Q is the output end of the switch unit 111, and the source electrode of the transistor Q is grounded. In the present embodiment, the timing unit 110 is not limited to a 555 timer, and the switching unit 111 may be implemented by a device having a switching function, such as an electronic switch. Further, the main control unit 120 is a solid state relay, but is not limited to a solid state relay, and the delay unit 121 is a time relay, and is not limited to a time relay.
Specifically, when the protection switch 16 of the charging device is turned on, the external power supply inputs an ac voltage of 220V to the charging device, and at this time, the indicator lamp 17 emits light. The power filter 15 receives the 220V ac voltage and filters the 220V ac voltage, and outputs the filtered 220V ac voltage to the dc power unit 130 and the main control unit 120, and the dc power unit 130 converts the filtered 220V ac voltage into a 24V working dc voltage to provide the 24V working voltage to each module in the charging device, where the working dc voltage converted by the dc power unit 130 is not limited to 24V, and different components in the circuit correspond to different working dc voltages.
When the automatic inspection equipment moves to a charging point, the automatic inspection equipment is firstly contacted with the ground pile 100 and the charging pile 101 of the charging device, after the local pile 100 and the charging pile 101 are well contacted with the automatic inspection equipment, the automatic inspection equipment automatically advances a preset distance and then is contacted with the detection pile 102, and after the automatic inspection equipment is well contacted with the detection pile 102, the ground charging contact inside the automatic inspection equipment is connected with the detection charging contact, so that the detection pile 102 outputs a detection enabling signal to the timing unit 110.
The low trigger pin 2 and the high trigger pin 6 of the timing unit 110 receive the detection enable signal, and the high trigger pin 6 receives the 24V operating voltage through the timing resistor R1, and the low trigger pin 2 is grounded through the timing capacitor C1. When the detection enabling signal is not received, the voltage of the low trigger pin 2 is discharged through the timing capacitor C1; when the detection enable signal is received, the voltage of the low trigger pin 2 may be determined by the voltage of the timing capacitor C1, and the voltage of the timing capacitor C1 may be determined by the time when the 24V working voltage charges the timing resistor R1. When the voltage of the timing capacitor C1 in the charging time, i.e. the preset time, is less than one third of the working voltage 8V, i.e. the voltage of the low trigger pin 2 is less than 8V in the preset time, the 555 timer is set to 1, i.e. the output pin 3 of the 555 timer continuously outputs a high level to the gate of the transistor Q in the preset time, so that the transistor Q is turned on, and after the transistor Q is turned on, the drain thereof outputs a driving signal to the main control unit 120. The control input pin 5 of the 555 timer is grounded through the capacitor C2, so that the introduction of interference can be effectively prevented.
The main control unit 120 receives an externally input ac voltage and a driving signal output by the transistor Q, and then outputs a logic control signal to the delay unit 121 according to the driving signal, and outputs the ac voltage to the dc charging unit 131, where the dc charging unit 131 converts the ac voltage into a charged dc voltage, and feeds the charged dc voltage back to the charging output unit 122, and the delay unit 121 controls the charging output unit 122 to output the charged dc voltage to the charging pile 101 according to the logic control signal after a preset delay time, so that the charging pile 101 charges the automatic inspection device. It should be noted that the output of the dc charging unit 131 is not limited to the dc voltage of 48V, and may be determined according to the devices with different voltage levels, and the preset delay time may be designed according to the device requirements.
In this embodiment, the 555 timer continuously outputs a high level signal to the transistor Q within a preset time period, so that the transistor Q outputs a driving signal to the main control unit 120, the main control unit 120 outputs a 220V ac voltage to the dc charging unit 131 according to the driving signal, and outputs a logic control signal to the delay unit 121, and the delay unit 121 controls the charging output unit 122 to output a 48V charging dc voltage converted by the dc charging unit 131 to the charging pile 101 after the preset delay time period, so as to charge the automatic inspection device. Because the 555 timer of the charging device of the invention outputs stably in the preset time, and the main control unit 120 enables the charging device to output alternating current firstly, and to output direct current after a period of time delay through the delay unit 121 so as to charge the automatic inspection equipment, the problems that the conventional charging equipment is easy to generate a sparking phenomenon when contacting with the automatic inspection equipment, and the charging equipment and the automatic inspection equipment are easy to be damaged by frequent contact are solved.

Specifically, when the protection switch 16 of the charging device is closed, the external power supply inputs an alternating voltage of 220V to the charging device, and at this time, the indication lamp 17 emits light. The power filter 15 receives the 220V ac voltage, filters the 220V ac voltage, and outputs the filtered 220V ac voltage to the dc power unit 130 and the first delay unit 181, and the dc power unit 130 converts the filtered 220V ac voltage into a 24V charging dc voltage to provide 24V working voltage to each module in the charging device.
When the automatic inspection equipment moves to a charging point, the automatic inspection equipment is firstly contacted with the ground pile 100 and the charging pile 101 of the charging device, when the automatic inspection equipment is well contacted with the ground pile 100 and the charging pile 101, the automatic inspection equipment continues to advance to be contacted with the detection pile 102 of the charging device, and because the charging contact in the automatic inspection equipment, which is contacted with the ground pile 100 and the detection pile 102, is connected, when the detection pile 102 is contacted with the automatic inspection equipment, the detection pile 102 outputs a detection enabling signal to a 555 timer.
The low trigger pin 2 and the high trigger pin 6 of the 555 timer receive the detection enable signal, and the high trigger pin 6 receives the 24V operating voltage through the timing resistor R1, and the low trigger pin 2 is grounded through the timing capacitor C1. When the detection enabling signal is not received, the voltage of the low trigger pin 2 is discharged through the timing capacitor C1; when the detection enable signal is received, the voltage of the low trigger pin 2 may be determined by the voltage of the timing capacitor C1, and the voltage of the timing capacitor C1 may be determined by the time when the 24V working voltage charges the timing resistor R1. When the voltage of the timing capacitor C1 in the charging time, i.e. the preset time, is less than one third of the working voltage 8V, i.e. the voltage of the low trigger pin 2 is less than 8V in the preset time, the 555 timer is set to 1, i.e. the output pin 3 of the 555 timer continuously outputs a high level to the gate of the transistor Q in the preset time, so that the transistor Q is turned on, and the source of the transistor Q outputs a driving signal to the solid state relay U1. The control input pin 5 of the 555 timer is grounded through the capacitor C2, so that the introduction of interference can be effectively prevented.
The main control unit 180 receives the driving signal and then outputs a first logic control signal to the first delay unit 181 and outputs a second logic control signal to the second delay unit 182, the first delay unit 181 inputs the 220V ac voltage received by the charging device to the dc charging unit 131 according to the first logic control signal after the first delay time (assuming that the first delay time is 5 seconds), the dc charging unit 131 converts the 220V ac voltage into a 48V charging dc voltage and outputs the 48V charging dc voltage to the charging output unit 183, and the second delay unit 182 controls the charging output unit 183 to output the 48V charging dc voltage to the charging pile 101 after the second delay time (assuming that the second delay time is 15 seconds) so that the charging pile 101 starts charging the automatic inspection equipment. It should be noted that the output of the dc charging unit 131 is not limited to the dc voltage of 48V, and may be determined according to devices with different voltage levels.
In this embodiment, the 555 timer continuously outputs a high level signal to the transistor Q within a preset time period, so that the transistor Q outputs a driving signal to the main control unit 180, the main control unit 180 controls the first delay unit 181 to operate first according to the first logic control signal so as to output an ac voltage of 220V to the dc charging unit 131, and the main control unit 1880 controls the second delay unit 182 to operate later according to the second logic control signal so as to control the charging output unit 183 to output a charging dc voltage of 48V to the charging pile 101, so as to charge the automatic inspection device.
