The communication and power supply system of the electric equipment on the arrow provided by the embodiment can simplify the equipment connection on the arrow, improve the system reliability and shorten the assembly time. As shown in fig. 3, according to the design concept of the present invention, an arrow-mounted computer is used as a core, the conventional communications between the single computers on the arrow, such as RS-422 communications or CAN communications, are unified into industrial ethernet communications based on gigabit ethernet lines as transmission media, and the power supply and distribution management of each single computer is implemented by applying an active ethernet design method. Specifically, a power supply controller is added at a power supply device such as an interface end of an rocket-borne computer for adding power supply bias to a network cable so as to supply power to a single-machine device at the back end. Because the signal transmitted by communication is a differential signal, a power supply bias is added to the signal wire, which is equivalent to increase of common-mode interference, so that the power supply mode does not influence the network communication between the signal wire and the signal wire. Similarly, a power receiving controller is added in the power receiving equipment at the back end for receiving the power supply input of the rocket-borne computer, and the power is supplied to a DC/DC converter at the next stage, and further the specific voltage value actually needed on the board is obtained through conversion, and the power supply process of the power receiving controller does not influence the reliable transmission of signals. Therefore, on the premise of ensuring the communication quality, related cables for power supply transmission are saved, the system connection relationship is simpler, and the complexity of a cable network on the rocket is reduced.
It should be noted that the invention utilizes a network cable to complete high-speed communication and power supply and distribution management between rocket-mounted devices, uses a traditional rocket-mounted computer as a control core of the rocket-mounted devices, and utilizes the network cable to realize information interaction with other single machines and power supply and distribution management of the single machines, namely, the rocket-mounted computer can control power-on of other designs, communicate with other single machines of a network, acquire state information of other single machines and send control instructions. The method can also be adopted to realize the communication and power supply requirements among other single machines on the rocket; because the standards of the POE network are different and the load carrying capacity is different, the implementation can be carried out according to the power consumption of the power receiving end equipment to carry out related device type selection and circuit design work, the scheme implementation proposal is carried out according to the IEEE802.3bt standard, the load end can support the maximum 71.5W power equipment, and the control power supply requirement of the traditional arrow equipment can be met; because the reliability requirement of rocket or missile equipment is high, the interfaces among the equipment can adopt a parallel redundancy design, and the system reliability is further improved; the connection between the devices preferably adopts a reinforced network port and seven or more network cables, so that the reliability of power supply and communication signal transmission of a single machine is reliably and effectively ensured; in order to ensure the reliability of communication, the communication between the rocket-borne computer and other single computers preferably selects industrial Ethernet communication protocols with higher reliability and stronger noise resistance, such as EthercCAT, Profinet and the like; in this embodiment, the arrow indicates that the interface end diode circuits of other single units can be optimized and adjusted to be field effect transistor circuits, so that the power loss on the diodes can be reduced, and the power supply requirements of the single unit product circuits can be guaranteed; the network interface RJ45 type standard interface can be used as a military shielding reinforced network connector, the connection mode of the network connector is generally bayonet or three-head thread connection, and the network connector has the outstanding characteristics of high reliability, environment resistance, vibration impact resistance, high waterproof grade and the like, and can further enhance the adaptability of the network connector in complex electromagnetic and mechanical environments.
Finally, it is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
