It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0020] like Figure 1 As shown in the figure, this utility model embodiment proposes an airborne wireless signal receiving device, including: a signal input circuit, a signal output circuit, a controller, a wireless communication module, a display module, a mode indicator circuit, and a button circuit; The signal input circuit is connected to the controller, and the signal input circuit is used to receive the data collection enable signal sent by the host computer and send it to the controller; The wireless communication module is connected to the controller. The wireless communication module is used to receive instruction data transmitted by external wireless devices and send it to the controller. The controller is used to collect the instruction data received by the wireless communication module. The controller is connected to the signal output circuit, and the controller is used to send the instruction signal corresponding to the instruction data to the host computer through the signal output circuit. The button circuit is connected to the controller, and the button circuit is used for switching working modes, setting communication frequency, and saving settings. The controller is connected to a mode indicator circuit, which is used to indicate the current operating mode. The controller is connected to a display module, which is used to display the instruction data, working mode, and communication frequency of the data collection.

[0021] In this embodiment, the controller uses a microcontroller, and a PLC is installed on the RGV as a host computer. The host computer executes specific instruction signals through the execution component. The controller receives the collection enable signal sent by the host computer through the signal input circuit, and sends the instruction signal corresponding to the instruction data to the host computer through the signal output circuit.

[0022] like Figure 2 As shown, the signal input circuit includes at least one input channel; Figure 2 One input channel was displayed; The input channel includes resistor R201, optocoupler U201, resistors R202, R203, R204, light-emitting diode D201, and capacitor C201; One end of resistor R201 is used to connect to the data collection enable signal sent by the host computer, and the other end is connected to the anode of the input side of optocoupler U201. The cathode of the input side of optocoupler U201 is grounded. The collector of the output side of optocoupler U201 is connected to the positive voltage VCC1. The emitter of the output side of optocoupler U201 is connected to one end of resistor R202, one end of resistor R203, and one end of resistor R204. The other end of resistor R202 is grounded. The other end of resistor R203 is connected to the anode of LED D201. The cathode of LED D201 is grounded. The other end of resistor R204 is grounded through capacitor C201 and connected to one input I / O port of the controller. When the host computer sends a +24V high-level signal to enable data collection, optocoupler U201 conducts, and the transmitter on the output side of optocoupler U201 reaches a high level. This transmits a +3.3V high-level signal to the controller via resistor R204 as a data collection enable signal, and the controller begins collecting instruction data received by the wireless communication module. Simultaneously, when the host computer sends a data collection enable signal, LED D201 illuminates. The host computer is a PLC with a high-level voltage of +24V, while the controller is a microcontroller with a high-level voltage of +3.3V. The positive voltage VCC1 is +3.3V, and the signal input circuit serves to perform level conversion and isolation. like Figure 3 As shown, the signal output circuit includes an optocoupler module U101, a solid-state relay module U103, and multiple output channels; in this embodiment, four output channels are provided, all with the same structure. The following description uses the first output channel as an example. One output channel includes resistors R101, R102, R109, R130, LED D101, and capacitor C101; One end of resistor R101 is connected to an output I / O port of the controller, and the other end of resistor R101 is connected to the anode of the input side of one optocoupler in optocoupler module U101.

The collector of the output side of one optocoupler in optocoupler module U101 is connected to the positive voltage VCC2.

The other end of resistor R102 is connected to one channel input terminal of solid-state relay module U103. One channel output terminal of solid-state relay module U103 is connected to one end of resistor R130 and one end of capacitor C101, and is used to connect to an input port of the host computer. The other end of resistor R130 is connected to the anode of LED D101. The cathode of LED D101 is grounded. The other end of capacitor C101 is grounded. The power supply terminal of solid-state relay module U103 is connected to the positive voltage VCC2. exist Figure 3In the example shown, the controller's Q1, Q2, Q3, and Q4 ports are connected to the first, second, third, and fourth output channels, respectively. The structures of the second, third, and fourth output channels are the same as those of the first output channel, only the component labels are different. The positive voltage VCC2 is +24V. The solid-state relay module U103 can be a VN340SP. After the controller receives the command data from the wireless communication module, it sends the corresponding command signal to the host computer through multiple output channels of the signal output circuit. For example, if the command signal is "forward", the controller's Q1 port sends a high level (+3.3V), the first optocoupler in the optocoupler module U101 is turned on, and the output terminal of the corresponding channel in the solid-state relay module U103 outputs a +24V high level. The host computer then receives the +24V high level signal at one of its corresponding input ports. The host computer then controls the RGV to perform the forward action. When the controller's Q1 port sends a +3.3V high level, the LED D101 lights up. In this embodiment, the signal output circuit includes four output channels, which are used for three control commands: forward, backward, and stop. There is also an output channel that can be used to send a confirmation signal to the host computer to confirm that the copy enable signal has been received. The signal output circuit can also serve as a level converter and isolation circuit. like Figure 4 As shown, the button circuit includes resistor R701, button S701, capacitor C701, resistor R702, button S702, capacitor C702, resistor R703, button S703, capacitor C703, resistor R704, button S704, and capacitor C704. One end of resistor R701 is connected to the positive voltage VCC1, and the other end is connected to one end of button S701, one end of capacitor C701, and a corresponding input I / O port of the controller; the other end of button S701 and the other end of capacitor C701 are grounded. One end of resistor R702 is connected to the positive voltage VCC1, and the other end is connected to one end of button S702, one end of capacitor C702, and a corresponding input I / O port of the controller; the other end of button S702 and the other end of capacitor C702 are grounded. One end of resistor R703 is connected to the positive voltage VCC1, and the other end is connected to one end of button S703, one end of capacitor C703, and a corresponding input I / O port of the controller; the other end of button S703 and the other end of capacitor C703 are grounded. One end of resistor R704 is connected to the positive voltage VCC1, and the other end is connected to one end of button S704, one end of capacitor C704, and a corresponding input I / O port of the controller; the other end of button S704 and the other end of capacitor C704 are grounded. Button S701 is used to enter frequency modulation mode (adjust the communication frequency of the wireless communication module), button S702 is used to save settings / exit frequency modulation mode, button S703 is used to adjust the communication frequency upward, and button S704 is used to adjust the communication frequency downward. like Figure 5 As shown, the mode indicator circuit includes resistor R705, LED D701, resistor R706, LED D702, resistor R707, and LED D703; One end of resistor R705 is connected to the positive voltage VCC1, and the other end is connected to the anode of LED D701, with the cathode of LED D701 grounded; one end of resistor R706 is connected to a corresponding output I / O port of the controller, and the other end is connected to the anode of LED D702, with the cathode of LED D702 grounded; one end of resistor R707 is connected to a corresponding output I / O port of the controller, and the other end is connected to the anode of LED D703, with the cathode of LED D703 grounded. The wireless communication module uses a 2.4GHz wireless module with a spectrum of 2400MHz to 2525MHz; the communication frequency of the wireless communication module can be set; the wireless communication module connects to the controller via an SPI interface; the following details the operating mode of the airborne wireless signal receiving device; 1. Standby mode; After the airborne wireless signal receiving device is powered on, it enters standby mode. In standby mode, the controller does not collect instruction data received by the wireless communication module. In standby mode, LED D701 is lit. After the airborne wireless signal receiving device is powered off, LED D701 is turned off. II. Messaging Mode; When the signal input circuit receives a +24V high-level data collection enable signal from the host computer, the controller receives a +3.3V high-level data collection enable signal; the airborne wireless signal receiving device then enters data collection mode. At this time, the controller collects the instruction data received by the wireless communication module, and then outputs corresponding control commands, such as forward, backward, and stop, to the host computer through the three output channels in the signal output circuit; that is, the three output channels output a +24V high level to the host computer accordingly; in data collection mode, the LED D702 flashes. When the data collection enable signal sent by the host computer goes low, the airborne wireless signal receiving device returns to standby mode; LED D702 turns off. III. Frequency Modulation Mode; In standby mode, press and hold button S701 for more than three seconds, and the onboard wireless signal receiving device will enter frequency modulation mode; at this time, LED D703 will flash; the display module will show the communication frequency, which is the communication frequency of the wireless communication module. A single click on button S703 increases the communication frequency by 1MHz, while a single click on button S704 decreases the communication frequency by 1MHz. Pressing and holding button S702 for more than three seconds saves the set communication frequency to the controller's Flash memory, then exits the frequency modulation mode, returns to standby mode, and LED D703 turns off.
