The specific embodiment
Referring to accompanying drawing 1, main control box comprises two CS module: CS1 and CS2, and two IO module: IO1 and IO2 also comprise COU module, SP module, KEY module in addition, and CS is connected with anxious words and the intelligent I/O module of having a power failure that comprises lock modules along the line.
Referring to accompanying drawing 2, power supply box 2 provides electric power for main control box 1, main control box 1 connects emergency stop switch 3, anxious words 4, smart phone 5, the terminal 6 of having a power failure successively by the CAN bus, wherein emergency stop switch 3, the anxious power failure are talked about 4 transmission distance and the settings of function needs according to belt conveyer, can be for a plurality of.Main control box 1 is connected with solid accumulation sensor 7, temperature sensor 8, Smoke Sensor 9, misalignment sensor 10, speed sensor 11, the vertical sensor 12 that tears by described intelligent I/O module, smart phone 5 by described external interface.
Referring to accompanying drawing 3, the CS module comprises detection signal transtation mission circuit 13, and back-signalling receives, treatment circuit 14.
Referring to accompanying drawing 4, the SP module comprises power circuit 15, control circuit 16, audio output circuit 17, interface 18, communicating circuit 19.
Referring to accompanying drawing 5, the COU module comprises imput output circuit 20, control circuit 21, communicating circuit 22, power circuit 23, interface 24.
Referring to accompanying drawing 6, the IO module comprises input detecting circuit 25, control output circuit 26.
The CPU of CS module, SP module, COU module, IO module all adopts chip PIC16F877A.
System realizes location to bus failure according to following principle:
Under the normal circumstances, after system powered on, the electronic switch of all lock modules was all opened.Controller sends a detection signal from data line, and have only first lock modules can receive signal this moment.Lock modules returns to acknowledge signal of controller after receiving detection signal, informs the state of controller self.Then, lock modules enters listening state with self electronic switch closes, and only recording does not have signal to transmit on data line, no longer the echo reply signal.After controller is received an acknowledge signal, the state of good first lock modules place phone of record.Then send a detection signal again, this detection signal will directly be passed to second lock modules by electronic switch, carries out and a last same action, by that analogy.Until terminal after controller is received terminal signaling, stops to inquire about work 1s along the line.During this period of time controller is presented at Query Result on the read-out, and makes corresponding action.The lock modules that is in listening state can not receive request signal all electronic switchs is resetted in 1s, wait for next query script.So repeatedly.
Controller is similar for the query pattern and the lock modules of intelligent lower computer and terminal, but the width of response pulse is different with lock modules, and controller is according to the width identification intelligent lower computer of responding pulse.
If fault just need realize locking by lock modules.Blocking function is to realize that by the oscillating impulse stack direct current signal that terminal is sent under the normal condition, system's block signal along the line is normal.Locking is pressed or the locking line opens circuit, and this signal disappears immediately, and the delivery port that is associated disconnects immediately, and belt stops immediately.Simultaneously controller changes the pulse width of request signal, inquires about which locking is pressed or where disconnected circuit is.
Determining when the beltman does abnormal condition to occur, main control box 1 carries out audio alert immediately, play cooresponding voice by the SP module in the main control box 1, tone frequency channel wire directly goes down voice transfer, the anxious words 4 that have a power failure, 5 pairs of voice of smart phone of installing along the line amplify the back to be play by loudspeaker, points out inspector along the line.In addition, the anxious words 4 that have a power failure, the smart phone of installing 5 along the line also has the distance communicating function, is used as wire telephony and uses.
System realizes the interlocking of belt up and down according to following principle:
Material is taken to down the belt transmission from epithelium, and this system start-up belt at present starts earlier, interlocks upwards with this.When belt stopped instantly, belt stopped on the interlocking.Interlocking has a dual mode, a kind ofly realizes by above-mentioned IO module, and hypodermis tape starting or give the epithelium band signal by the delivery port of IO module when stopping, last belt detects belt down by the input port of designated I module, guarantees to interlock normally sequential.Another kind is to realize by the CAN bus by interlocking unit COU module special-purpose in the controller.
