Accompanying drawing explanation
Fig. 1 is the circuit structure diagram of a kind of post house of this utility model formula communication intelligence node.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in detail.
nullThis utility model one post house formula communication intelligence node，Structure is as shown in Figure 1，Including controller，On the cable V+ of the cablet that the 3rd i/o mouth of controller is connected in pipeline after being connected with switch K2，The power end VC of controller is connected with charging chip outfan Cout，Oneth i/o mouth of controller is connected on the cable V+ of cablet after being connected with switch K1，Switch K1 is connected with the 2nd i/o mouth of controller again，Simultaneously，Switch K1 is connected to again charging chip after connecting resistance R，Ground connection after the electrical energy inputs connection electric capacity C1 of described charging chip，Electric capacity C2 it is connected between C+ and C-of charging chip，The outfan Cout of charging chip and earth terminal are also connected with being with tapped super capacitor C，It is denoted as electric capacity C3 and electric capacity C4，Wherein，Switch K2 is N-channel enhancement mode mos pipe，Switch K1 is P-channel depletion type mos pipe，Controller model is MSP430，Charging chip model is Itc3225.
The specific works principle of intelligent node is:
nullV+ in Fig. 1，Vr is two cablets being close on service pipeline inwall，Vr is as reference potential cable，Electrical switch K1 adopts P-channel depletion type mos to manage (closed type)、Switch K2 adopts N-channel enhancement mode mos to manage (open type)，In pumping plant, PC determines whether to switching circuit to communications status according to the charging current gathered on circuit，When being switched to charged state，K1 closes，K2 disconnects，In pumping plant, the super capacitor in intelligent node is charged by power supply by two Thin cables，Wherein Itc3225 is charging chip，The output Vout of Itc3225 is supplied in node MSP430 controller electric energy，When K1 disconnects，K2 closes，It is switched to communications status，In pumping plant, PC carries out post house formula by two Thin cables with flaw detection robot in intelligent node and pipeline and communicates，On link, in intelligent node, MSP430 controller board inter-stage carries out half-duplex operation by serial ports RX/TX single line，Intelligent node is communicated by NFC radio receiving transmitting module wireless short-range with flaw detection robot.
nullConcrete，Electric capacity is charged by chip Ltc3225，When electric capacity C is charged to about 2.5V, MSP430 obtains electric work，When electric capacity C charges to 5.3V，MSP430 obtains the interrupt signal PGOOD from Itc3225，MSP430 sends high level signal makes the normally-closed contact of switch disconnect to the G pole pin of P-channel depletion type mos，Node 1,2 ... in n, Itc3225 and super capacitor are extractd successively from power bus，Pc machine is by charging current on Hall current sensor monitoring bus in the meantime，When it is less than a certain threshold value，Cut off the connection of pumping plant place DC source and bus，Hereafter，Node 1,2 ... in n MSP430 send out control signal to K2 switch N-channel enhancement mode mos pipe G level pin high level make the normally opened contact of switch close，Node 1,2 ... n is sequentially communicated V+，Vr，Namely multiple intelligent nodes in parallel between two cablets are formed.PC in pumping plant, multiple intelligent node and mobile terminal pipeline inspection robot form communication links by two thin cable, it is possible to carry out post house formula communication.
This utility model one post house formula communication intelligence node, cablet in pipeline embeds intelligent node at interval of certain distance, intelligent node on link adopts super capacitor to power, super capacitor is charged by cablet, wireless short-range communication is adopted between flaw detection robot and intelligent node in pipeline, carrying out post house formula wire communication between intelligent node, whole system is low in energy consumption.
