In the embodiment of the present invention, the 433MHz transceiver circuit shown in fig. 2 is adopted, wherein the camera 11, the action executing unit 12, the control unit 13, the temperature sensor 14, and the flow sensor 15 all include the 433MHz transceiver circuit shown in fig. 2; 433MHz transceiver circuit, wireless transmission can adopt loop antenna structure, and power module 16 has output voltage of U_DDAnd = 3V, which supplies an operating voltage to the loop antenna, and the loop antenna transmits a signal received at 433MHz to ANT1 and ANT2 pins of the nRF401 chip, and receives the signal by the nRF401 chip. Wherein, a crystal oscillator circuit of the nRF401 chip is formed by R1, JT, C1 and C2, a loop filter is formed by C3, C4 and R2, and R3 is a power setting resistor; c5 is a power supply decoupling capacitor, and C6 and C7 are noise elimination capacitors. The DOUT end is connected with the RXD (serial input) end of the singlechip. It should be noted that the nRF401 chip is a single UHF wireless transceiver chip developed by Nordic corporation, and operates in the 433MHz frequency band. In receive mode, the nRF401 chip is configured as a conventional heterodyne receiver, and the received radio frequency modulated digital signal is amplified by a low noise amplifier, converted to an intermediate frequency by a mixer, amplified, filtered, and then fed to a demodulator. After demodulation, the signals are converted into digital signal output (DOUT end); when the TRX _ CE pin is high and the TX _ EN pin is low, the nRF401 enters a shockburst receiving mode, after 650us, the nRF401 continuously monitors and waits for receiving data, when the nRF401 detects a carrier wave in the same frequency band, the carrier wave detection pin is set high, when a matched address is received, the address matching pin is set high, and a received signal is input through the DIN pin.

In the embodiment of the present invention, the RS485 transceiver circuit shown in fig. 3 may be used to connect the control unit 15 and the upper computer 2. Wherein the transmitting and receiving work flow of the nRF24L01 is as follows:

in transmitting data, nRF24L01 is first configured into transmit mode: writing a receiving node address TX _ ADDR and valid data TX _ PLD into an nRF24L01 buffer area through an SPI according to time sequence, wherein the TX _ PLD must be continuously written when CSN is low, the TX _ ADDR can be written once when transmitting, then CE is set to be high level and kept for at least 10 mu s, and data is transmitted after delaying for 130 mu s; if auto-acknowledge is on, nRF24L01 enters receive mode immediately after transmitting data, receiving an acknowledge signal (the auto-acknowledge receive address should coincide with the receiving node address TX _ ADDR). If the response is not received, the data is automatically retransmitted (the automatic retransmission is started), if the retransmission time (ARC) reaches the upper limit, the MAX _ RT is set high, and the data in the TXFIFO is reserved for retransmission again; when MAX _ RT or TX _ DS is set high, the IRQ is lowered, an interrupt is generated, and the MCU is notified. When the last transmission is successful, if CE is low, nRF24L01 enters idle mode 1; if the sending stack has data and the CE is high, entering next transmission; if there is no data in the transmit stack and CE is high, then idle mode 2 is entered. When receiving data, nRF24L01 is first configured to receive mode, and then the delay of 130 μ s into the receive state waits for the arrival of data. When the receiver detects a valid address and CRC, the packet is stored in the RXFIFO with the interrupt flag RX _ DR high and the IRQ low, generating an interrupt, informing the MCU to fetch the data. If the automatic response is started at the moment, the receiver simultaneously enters the transmitting state to transmit back the response signal. Finally, if CE goes low, nRF24L01 enters idle mode 1.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, various changes and modifications can be made by the owner of the patent within the scope of the appended claims, for example, as long as the protection scope described in the claims of the present invention is not exceeded.
