Problems solved by technology

[0010] It can be seen from the above that the address identifier in the communication protocol is basically related to the physical location. Especially, in the application of the serial communication system with multi-scenario, multi-owner and multi-computer operation, where the system master and each slave device are located In fact, the scene subtypes, geographical locations, and working conditions of the aircraft are heavily related to the speed, convenience, and reliability of the communication system. However, the related configurations in the existing technology are manually operated, adjusted, and adjusted on site according to the design manual. check, very inconvenient

Embodiment 1

[0110] A system for serial communication address setting, such as Figure 8 As shown, it includes a low potential terminal BP- and a high potential terminal BP+ in the electrical environment, and the serial communication port nBPC electrically connected to the electrical environment is a bus mode half-duplex serial communication, and the terminal BP- It is the benchmark reference point for the serial communication system and address signal detection of the multiple groups of operations; wherein, the system consists of a charging system monitor CMU, an AC input rectifier module RM1-5, a DC input converter module CM1-4, a battery charging Composed of bin BH1-12, to realize the autonomous charging of the removable smart lithium battery nBRP1-12 inserted into the battery bin of the charging cabinet.

[0111] In Embodiment 1 of the present invention, the method includes the following steps:

[0112] Step S11, select the nLA mode of the resistance fixed value controlled common nega...

Embodiment 2

[0151] Embodiment 2 of the present invention, see Figure 5 , Figure 7 , Figure 9 , the port controlled parameter is selected as the fixed-value resistance Rx, Rx=Rc*(Vt1 / Vt2-1), where Vt1=Vp, when the sequence number corresponding to Vt2 is selected as an arithmetic linear preset and related to Vp, that is, the port The control method of electrical parameters is: fixed value resistance and the voltage drop is proportional to the terminal voltage. In this example, select: Vt2 / Vt1=i / N, set N=40, Rc=200K, have Ri=Rc*(N / i-1), see Figure 5 right subplot and Figure 7 , it can be seen that the parameter range of the position port voltage is between BP+ and BP-, and it decreases evenly according to the position number; the output signal of the detection circuit is the measurement amplitude range of the composite MCU / DSP smart chip AD between 0-Vdd ; When selecting the communication address 01h-0Ch of R10-R21 corresponding equipment 01#-12#, address AC=AL-9, sequence number iL...

Embodiment 3

[0153] Embodiment 3 of the present invention, see Figure 10 , the circuit of the physical position port is given. In this example, the voltage fixed value controlled electrical parameter is selected, the common negative terminal BP- is selected as the detection reference point, the controlled voltage base value / step value Vu=75mV is selected, and the position address Select 01-32#, and the communication address corresponds to 00h-1Fh or 01h-20h according to the needs, or other choices; in this example, the dial switch mode is selected, and the port circuit generates a controlled digital voltage source signal output, and the output port There are short-circuit, anti-voltage protection diodes and current-limiting resistors. In this example, a single position port can also be modified to set any agreed address, and the setting is not on the device side but on the side to be connected to the system. It is especially suitable for The use of test tooling is also suitable for test b...

Abstract

The invention discloses a method and a system for setting an address of serial communication equipment. The method comprises the following steps: configuring an element or a circuit at a to-be-accessed physical position interface side of the system to form a resistance / voltage / current electrical parameter constant value or proportion controlled signal interface, selecting an effective working rated range value domain, correspondingly appointing an effective coding integer value range of a physical address, formulating an equipment communication address conversion table, and realizing communication address calibration at the to-be-accessed side. By connecting a physical position port, the access device autonomously detects and recognizes controlled electrical parameters, recognizes positioncodes and sets a communication address, manual intervention is not needed, and use and maintenance are easy. The controlled electrical parameters can be effectively, clearly and accurately calibrated, the physical position, the scene and the machine position working condition are associated, the access equipment can rapidly and independently detect the controlled electrical parameters and configure the unique communication address, and the rapidity, convenience and reliability of serial communication connection are improved.

Description

technical field [0001] The invention relates to the field of data transmission of communication equipment, in particular to a serial communication system with multi-scenario, multi-owner and multi-device operations. Background technique [0002] Serial interface communication is a common method of data transmission between equipment or between equipment internal components, including agreed standard circuit form, transmission protocol, transmission rate, data format and other technical content. [0003] The universal asynchronous transceiver controller UART is a general serial data communication system; the early application of the RS232C standard serial interface is a master-slave online mode, and the later upgraded USB serial interface is also a master-slave mode; RS232C is developed later RS422 / RS485 standard serial communication system, one master multi-slave online mode, using fixed preset address and designated master, the master sends communication commands or query d...
