Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0034] like Figure 1 As shown, the wireless remote control ignition control device based on the airport bird repeller provided by the utility model includes: a single chip microcomputer, a wireless communication module, an NMOS tube switch circuit, a power supply module, a large capacitor charge and discharge circuit, and a nickel-chromium wire ignition mechanism. Among them, the wireless communication module involved in this embodiment adopts a 433M module; the single chip microcomputer adopts an STC single chip microcomputer, and an ARM microprocessor and the like can also be adopted. An NMOS tube is provided in the NMOS tube switch circuit, and the model of the NMOS tube is IRF4368.

[0035] The nickel-chromium wire ignition mechanism can ignite the bird-repelling cannon. The nickel-chromium wire ignition mechanism is provided with a nickel-chromium wire U1; in order to supply power to the nickel-chromium wire U1, the nickel-chromium wire U1 can be burned red, thereby igniting the bird-repelling cannon.

[0036] The first end of the nickel-chromium wire U1 of this embodiment is connected to the 35V ignition power supply; the output end of the power supply module is connected to the input end of the large-capacitor charge and discharge module, and the single-chip microcomputer is connected to the control switch of the large-capacitor charge and discharge circuit; the output end of the large-capacitor charge and discharge module outputs the 35V ignition power supply; the second end of the nickel-chromium wire U1 is connected to the drain of the NMOS tube in the NMOS tube switch circuit, and the source of the NMOS tube in the NMOS tube switch circuit is grounded; in order to enable remote sending of the ignition signal and realize remote control, the single-chip microcomputer is connected to the control terminal through the wireless communication module to obtain the ignition signal.

[0037] The control terminal may include mobile terminals such as mobile phones, smart phones, laptop computers, personal digital assistants (PDA), tablet computers (PAD), etc. and fixed terminals such as digital TVs, desktop computers, etc.

[0038] The power supply method of the wireless remote control ignition control device of the utility model is that the power supply module is provided with a photovoltaic power generation panel, a photovoltaic power generation controller and a battery. The photovoltaic power generation panel is connected to the battery charging end through the photovoltaic power generation controller; the power supply end of the battery is connected to the input end of the large capacitor charging and discharging module.

[0039] The photovoltaic power generation panel can charge the battery through the photovoltaic power generation controller.

The photovoltaic power generation controller can control the photovoltaic power generation panel to charge the battery according to the battery power state. The photovoltaic power generation controller can adopt the commonly used models in the photovoltaic power generation field.

[0040] In order to provide a large current to the nickel-chromium wire ignition mechanism and quickly heat the nickel-chromium wire, the large capacitor charging and discharging module is provided with a DC-DC boost circuit and two large capacitors arranged in parallel; the positive terminal of the DC-DC boost circuit is connected to the positive terminal of the large capacitor through a charging circuit, and the negative terminal of the DC-DC boost circuit and the negative terminal of the large capacitor are grounded respectively; a control switch is provided on the charging circuit.

[0041] Specifically, the large capacitor charging and discharging module is to DC-DC boost the 12V voltage output by the battery to 35V. The two large capacitors set in parallel are 33000uF capacitors. The large capacitors are charged first. To ensure charging safety, the charging circuit is controlled by a control switch. The charging circuit can be connected in series with a 47Ω / 6W high-power winding resistor. After charging the two large capacitors set in parallel, the large capacitors emit a large current to quickly heat the nickel-chromium wire to meet the ignition needs of the airport bird repellent.

[0042] The wireless remote control ignition control device of the utility model is mainly used for igniting the airport bird repeller. The single chip microcomputer, wireless communication module, NMOS switch circuit, power supply module and large capacitor charge and discharge circuit can be installed in the electric control box. The nickel-chromium wire ignition mechanism is used in conjunction with the airport bird repeller.

[0043] For example, when the airport bird repeller and the wireless remote control ignition control device are used together, a control console, a relay station and several gun mounts can be set up. The airport bird repeller is installed on the gun mount. The nickel-chromium wire ignition mechanism is installed on the gun mount. The relay station can be installed with photovoltaic panels, photovoltaic power generation controllers and batteries. Wireless communication modules and antennas for wireless communication can also be installed. The wireless communication module can be two RF 433M wireless modules. The single-chip microcomputer in the electric control box can use the STC12C5A60S2 dual-serial port single-chip microcomputer, which is connected to the 433M module to control the passage of data, and set a FIFO cache queue on each serial port receiving side to screen the received instructions and data, exclude and discard possible interference data, and set the transceiver status indicator for the two 433M wireless modules.

[0044] In the utility model, Figure 2As shown, the NMOS tube switch circuit includes: a TLP250 photocoupler, a resistor Rt10, a resistor Rt11, a resistor Rt12, a resistor Rt13, a light emitting diode LED, an NMOS tube Q1 and a diode Dt1; the second pin of the TLP250 photocoupler is connected to a 5V power supply through the resistor Rt10; the three pins of the TLP250 photocoupler are connected to a single-chip computer; the seven pins of the TLP250 photocoupler are connected to the first end of the resistor Rt11, and the second end of the resistor Rt11 is respectively connected to the anode of the light emitting diode LED, the first end of the resistor Rt13 and the gate of the NMOS tube Q1; the cathode of the light emitting diode LED is grounded through the resistor Rt12; the second end of the resistor Rt13 is grounded; the drain of the NMOS tube is respectively connected to the second end of the nickel-chromium wire and the anode of the diode Dt1, and the cathode of the diode Dt1 is connected to the 42V power supply.

[0045] The microcontroller heats and ignites the nickel-chromium wire through the NMOS tube switch circuit. The gate threshold of the NMOS tube is V gs(th) Voltage 4V, V DSS The voltage is 75V, the on-resistance RDS≤1.85mΩ, the continuous source current is <350A, and the TLP250 photocoupler input is connected to the output of the microcontroller IO port after the 74HC245 inverter. When the microcontroller IO port outputs a high-level pulse ignition pulse, it is converted into a low-level pulse through the inverter, and then outputs a high-level pulse to the G pole of the NMOS tube through the photocoupler. The energy charged by the capacitor is released within the high-level pulse interval.

[0046] The nickel-chromium wire in the nickel-chromium wire ignition mechanism can be a nickel-chromium wire with a diameter of 0.6mm. The nickel-chromium wire is installed on the ceramic block at a length of 1.5cm and connected in series with the S pole of the NMOS tube switch to ground. When the large capacitor is fully charged, the capacitor energy is instantly released to the nickel-chromium wire through the NMOS tube, and the nickel-chromium wire can be instantly burned red, thereby achieving the purpose of igniting the bird-repelling bomb fuse. For the convenience of installation, two wiring boards are designed and installed on both sides of the gun mount. In order to facilitate wiring, a wiring board can be set, one end of which is connected to the NMOS tube discharge output line in the NMOS tube switch circuit, and the other end of the wiring board is directly welded to the ceramic block of nickel-chromium.

[0047] The single chip microcomputer realizes communication connection with the control terminal through the wireless communication module to obtain the ignition signal.

[0048] The 433M module is used as the wireless communication module, which has a TTL serial port and can communicate with the single-chip microcomputer serial port. The STC single-chip microcomputer control part can also be connected to include a 485 display module and control buttons. It can also be connected to a dip switch circuit, and the controller wireless communication mode can be selected by the dip switch.

[0049] The STC microcontroller can also be connected to a USB to serial port circuit, which includes a PL2303 chip and its peripheral circuits. The STC microcontroller can achieve data communication with the control terminal through the USB to serial port circuit and then achieve communication with the control terminal.

[0050] In the utility model, Figure 3 As shown, the device also includes: a short circuit detection circuit; the short circuit detection circuit includes: a resistor R100, a resistor R101 and a voltage-stabilizing diode DZ1; the first end of the resistor R100 is connected to a 35V ignition power supply, and the second end of the resistor R100 is respectively connected to the first end of the resistor R101, the positive end of the large capacitor C100, the cathode of the voltage-stabilizing diode DZ1 and the single-chip computer; the second end of the resistor R101 and the anode of the voltage-stabilizing diode DZ1 are respectively grounded.

[0051] The function of the short-circuit detection circuit is that when the NMOS tube is short-circuited, the large capacitor charging and discharging module only has a loop impedance of nickel-chromium wire with very low impedance, and the 35V charging voltage directly reaches the ground through the 47Ω / 6W high-power winding resistor, which will cause the large capacitor to fail to charge successfully. The microcontroller can detect the power-on voltage of the large capacitor based on the voltage on both sides of the resistor R101, and then it can be determined whether the charging is successful.

[0052] For the short-circuit detection of the NMOS tube, if the NMOS tube is short-circuited, the voltage C_35V on the large capacitor will always be a low level, and the microcontroller IO port MCU_P11 can only detect a low level, thereby realizing short-circuit detection. When MCU_P11 detects a low level, it closes the charging enable port, stops charging, and sends an alarm to the control terminal through the wireless communication module, indicating a short-circuit fault of the NMOS tube.

[0053] Combined with the short circuit judgment process, the execution process of the wireless remote control ignition control device is as follows: Figure 4 The flowchart shown in the figure shows that the format of the received wireless command data is checked in the command processing program, and the wrong received command is discarded.

[0054] In the utility model, the wireless remote control ignition control device can be used in the bird-repelling system of the airport, and the communication distance of the 433MHz wireless communication module with a power of 100mW is up to 1.5km. The utility model can also increase the communication distance by adding a relay station, and also use a 433MHz wireless module. At the same time, the relay station is installed on the roof of a taller building in the middle of the airport, and a fiberglass antenna with a gain of more than 8dBi is used, so that the communication distance can be extended to more than 4.5 kilometers, completing the overall range that can cover the general airport. The relay station is installed at a higher position, which can avoid some ground electromagnetic interference and increase the stability of wireless communication. FIFO cache and data format judgment program can also be set to increase the fault tolerance of the system, and when there is erroneous data or missed data, it will not affect the use.

[0055] As a communication mode, compared with the wireless communication mode adopting 4G, because it uses network communication protocol, the protocol is complex and the data volume is large, and a network server is needed, so that a remote ignition operation delay is between 2 seconds and 5 seconds. And the mode of using 433MHz wireless communication, the communication protocol is simple and the data volume is small, does not need a network server, and a remote ignition operation delay can be completed within 1 second. Simultaneously in ignition control, the energy of large capacitor pre-charged electricity is discharged, and the capacitor discharge can complete the discharge within the millisecond time, which ensures the timeliness of bird driving. Relative to the electronic gun bird driving mode, the wireless remote control ignition control device of the utility model can directly ignite the bird driving bomb fuse, does not need a special electronic gun, and reduces the cost of ammunition.

[0056] The utility model has a stable and reliable wireless communication method and adopts solar power supply. The wireless remote control ignition control device can be placed at will within the airport according to the need of bird repelling. At the same time, if it is necessary to strengthen the bird repelling force at a certain position, multiple gun mounts can be placed at that position. The control terminal can combine multiple gun mounts at the same position into a two-in-one, three-in-one or four-in-one new gun mount, which can simplify the control interface and improve the local bird repelling effect.

[0057] The wireless remote control ignition control device of the utility model can be implemented in hardware, software, firmware or any combination thereof. The various features described as modules, units or components can be implemented together in an integrated logic device or separately as discrete but interoperable logic devices or other hardware devices. In some cases, the various features of the electronic circuit can be implemented as one or more integrated circuit devices, such as an integrated circuit chip or chipset.
