Embodiment
As shown in Figure 1, this device is made up of a plurality of station terminals, service terminal, main frame, upper PC etc.
The system bottom network is the RS485 bus network of being made up of single-chip microcomputer, and main frame is got in touch by polling mode and each extension set.Each extension set single-chip microcomputer adopts the 89C51 chip of Atmel company, and the data that its RS232 mouth sends convert the RS485 signal to through the RS485 chip and transmit on the net.RS485 communication mode transmission range can reach 1.2 kilometers, all can effectively cover the general industrial factory building.Operational terminal and service terminal all belong to the extension set of this network, reliable for guarantee information transmission, and each group information all sends twice, contrasts just to give affirmation after identical.Each extension set is by the address identification, and geocoding adopts dial switch, makes each terminal interchangeability stronger.
Fig. 2 is the schematic block circuit diagram of station terminal.The CPU that the station terminal adopts is the 89C51 single-chip microcomputer, and this CPU is connected with a LCD display board, a keyboard, loudspeaker, an address dish, a house dog and a state lock and forms.By LCD LCD2
*20 information of carrying out show.By 10 bit keyboards, the information that input is necessary, loudspeaker then are used for informing sending of call signal.The address dish is used for determining the address of this terminal.The state lock is used for limiting unwarranted user.House dog is used for guaranteeing that CPU can not crash.Power supply adopts 48VDC/5VDC.The RS232 interface of CPU1 inserts the RS485 bus by a RS485 chip.
As shown in Figure 3, service terminal also adopts 89C51 singlechip CPU 2, and this single-chip microcomputer is connected with a LCD4
*20 LCD, a four-bit keyboard, loudspeaker, an address dish and a house dog.Show by the LCD information of carrying out, carry out the information input by keyboard.Loudspeaker then are used for informing the reception of call signal.The address dish is used for determining the address of service terminal.House dog is used for guaranteeing that CPU2 does not crash.Power supply adopts a 48VDC/5VDC power supply.The RS232 interface of CPU2 inserts the RS485 bus by a RS485 chip.
As shown in Figure 4, main frame adopts the DS80C320 singlechip CPU 3 of two RS232 mouths, is connected with the RS485 chip by one of them RS232 mouth, is used to control whole RS485 bus, be connected with the RS232 chip with another one RS232 mouth, get in touch with upper PC in order to maintenance.House dog is used for guaranteeing that CPU3 can not crash.Power supply adopts the 48VDC/5VDC power supply.
The entire work process of this device is as follows:
Each service department is provided with a service terminal, and each station is provided with a station terminal.Now be divided into (1) operate as normal (2) equipment failure the full time with a station and shut down (3) (4) planned shut-down (5) of remodeling and lack five parts such as material grade, all working time must be one of them.During station terminal normal boot-strap, automatically enter " operate as normal ", when the duty of this station changes, this station field personnel can be by the keyboard input service state of station terminal, the working state signal and the address of station terminal are sent to main frame, if this signal is the signal that belongs to attendant's service of needs service middle-end, then the corresponding service terminal of host computer control sends alerting signal, and the station terminal address and the KOC kind of call of show Calls.Call out the associated production line attendant.The kind of calling out is set to following three kinds: (1) maintenance: flight-line maintenance or electrical repair.(2) feeding person (3) zero parts replacement personnel.After corresponding attendant arrived the calling station and finishes service, the open mode lock was provided with new state.For example work as station and enter " lacking material " state from " operate as normal " state, then the station personnel " lack and expect " signal in this station terminal input, then the signal of this state is sent to the service terminal at feeding person place through main frame, call out feeding person, feeding person then can arrive this station according to the station position and the demand of service terminal demonstration, after feeding finishes, the open mode lock is provided with new station state and is " operate as normal ".Then import and be this interval time " lacking material " duration from " lack material " state once more " operate as normal " state of being input to.
Service terminal also can be connected with a radio paging system, when the attendant not when specifying station, the staff that can make an inspection tour by the radio paging system paging.
Above field data, promptly time that each duty continued etc. can be all main frame by this device be sent in the upper PC, chart by host computer is programmed, writes down, gathers, analyzes, draws.And, make more PC share to these data by the PC network server, realize remote monitoring.
PC upper machine communication program adopts the MSComm control.The BP call information that the PC host computer is sent main frame here is transferred to Modem, is transferred to public wireless paging centers by Modem, sends radio call information.
Device adopts the single power supply powering mode.Join one of UPS, one group on 48V accumulator is powered to total system with DC48V.Each terminal adopts high frequency switch power to convert DC48V to DC5V for its use.If civil power disconnects, battery pack can be powered 10 hours to total system.
