During setting, the setter 3 is operated by the user, and its receiver 4 is arranged at a guided ammunition such as a missile / rocket. The setting control circuit 31 in the setter 3 obtains setting information from the host computer 1 and generates a microwave signal containing the setting information. After the microwave information is amplified by the microwave power amplifier 32, the transmitting antenna 33 transmits the microwave signal to the outside. The receiver 4 located at the guided ammunition receives the microwave signal through the receiving antenna 43, and the energy conversion circuit 42 converts and stores the microwave energy. When the stored power reaches a certain threshold, it is boosted and regulated to supply power to the receiving control circuit 41. After the receiving control circuit 41 is powered on, it demodulates the communication signal in the microwave energy, stores the information transmitted by the setter 3, and sends it to the on-board terminal 2 to finally complete information setting.

[0029] Further, the on-board terminal 2 of the present invention refers to an electronic computer arranged on a guided ammunition such as a missile / rocket. During the setting operation, the receiver 4 is connected to the data power supply interface of the guided ammunition such as a missile / rocket in a wired connection manner.

[0030] Further, the frequency range of the microwave energy in the present invention can be selected as 2.4 GHz to 2.525 GHz and 5.725 GHz to 5.85 GHz.

[0031] Further, the transmitting antenna 33 is a microstrip array antenna, and the receiving antenna 43 is an omnidirectional microstrip antenna.

[0036] Exemplarily, the receiving antenna 43 receives the microwave energy emitted by the setter 3. The vast majority of the microwave energy is converted into electrical energy by the energy conversion circuit 42 and stored. When the stored electrical energy exceeds the threshold set by the voltage comparator 412, the electrical energy stored by the energy conversion circuit 42 starts to be output to the Boost circuit 413, and finally the power supply for the second microwave communication chip 414 and the second MCU 411 is realized. The Boost circuit 413 mainly realizes the functions of boosting and voltage regulation to ensure the stable power supply of the load circuit. Part of the microwave energy is input into the second microwave communication chip 414 through the second filter 415. After being powered on, the second microwave communication chip 414 demodulates the microwave signal for communication. The second MCU 411 stores the setting information obtained after communication demodulation and sends the setting information to the on-board terminal 2.

[0037] Preferably, as an alternative embodiment of the present invention, the second microwave communication chip 414 uses NRF2401P, the voltage comparator 412 uses MAX9064EUK+, and the Boost circuit 413 uses a synchronous rectifier boost converter chip.

Among them, the energy conversion circuit, the voltage comparator 412, and the Boost circuit 413 constitute a microwave power supply circuit, while the on-board power supply and the voltage regulator 416 constitute a wired power supply circuit. The isolation circuit 417 is used to make the two sets of power supply circuits not interfere with each other.

[0039] See Figure 5 Exemplarily, the isolation circuit 417 is composed of two diodes D1 and D2.

The energy conversion chip 422 is electrically connected to the storage capacitor 423, and the storage capacitor 423 is electrically connected to the voltage comparator 412. Exemplarily, the storage capacitor 423 is composed of multiple tantalum capacitors connected in parallel.

[0041] See Figure 4 , the communication coupling circuit 421 is composed of capacitors C1, C2, C3, and resistor R1. The microwave energy received by the receiving antenna 43 is connected to capacitor C1 from input port one. Capacitor C1, resistor R1, and capacitor C2 form output port two. Capacitor C1 and capacitor C3 form output port three. Output port two is electrically connected to the energy conversion chip 422, and output port three is connected to the second filter 415. Most of the microwave energy is transmitted to output port two as the input of the energy conversion chip 422, and the energy conversion chip 422 can convert the microwave energy into electrical energy. The storage capacitor 423 is used to store the electrical energy. When the electrical energy stored in the storage capacitor 423 exceeds the threshold set by the voltage comparator 412, the electrical energy stored by the energy conversion circuit 42 starts to be output to the Boost circuit 413. At the same time, a small amount of microwave energy is transmitted to output port three as the input of the second filter 415 with communication anti-interference function.

[0042] Preferably, as an alternative embodiment of the present invention, the capacitance values of C1, C2, and C3 are 47 pF, and the resistance value of R1 is 100 ohms.

[0043] While the setter 3 sends setting information to the receiver 4, the receiver 4 also sends feedback information to the setter 3, and the information communication between the two adopts the time-division multiplexing method.
