Embodiment
Shown in Figure 1, the present invention is provided with control module 1, control module 1 is comprised of processor 8, Ethernet interface 9, usb 10, debug serial port 11, and power module 2 has the two-way output sub-module and Voltage stabilizing module 4 forms, and power supply is changed out the output of three road direct currents through voltage stabilizing output.Ethernet interface 9, usb 10, debug serial port 11 link to each other with processor 8 respectively, the processor 8 of control module 1 also connects respectively power module 2, watchdog circuit 3, level switch module 7, watchdog circuit 3 adopts hardware watchdog circuit, be used for exceeding schedule time running time when main program, circuit sends reset signal, and the main program guiding principle is entered normal running status.Level switch module 7 links to each other with interface module 6 through photoelectric isolation module 5, and interface module 6 comprises RS485 interface 12, RS232 interface 13 and usb 10.RS485 interface 12 quantity are 4, and each port all can realize and the slave computer command interaction, and RS232 interface 13 quantity are 1, are used for debugging.
Power module: stable power supply is the prerequisite of system's reliably working, and power module 2 is comprised of two parts, and first lithium battery is used for powering to real-time clock.Another part adopts power output large, flexible design, energy-efficient integrated off-line type TOPSwith-GX series switch power supply, whole system nucleus module needs+3.3V direct current supply, part of interface needs+5V direct current supply.
Switching Power Supply is taken from power module 2 input, altogether two-way input, be respectively+the 10V/0.8A direct current and+the 8V/1.5A direct current.Change out the output of three road direct currents through the voltage stabilizing chip, be respectively+5V, VCC and+3.3V, pass through transformer isolation between+5V and the other two-way output, + 5V is used for to photoelectric isolation module 5 outlet sides and RS485 interface 12 and 13 power supplies of RS232 interface, VCC and+3.3V is used for to photoelectric isolation module 5 input sides and other chip power supply.
Control module 1: as the control core of data server, the applied environment of considering data server is in the factors such as open air of strong electromagnetic even high temperature, high humidity, consider simultaneously economy, reliability, requirement of real-time and the system interface demand of data server, select the technical grade acp chip.
After the core CPU control chip was selected, processor 8 was directly selected in the market supply abundance, and reliability is high, the CPU module of reasonable price.
Interface hardware: on the module with memory cell such as FLASH, SDRAM and FRAM, can satisfy data server for the needs of program and data storage, peripheral hardware and bus are then directly drawn by 2 50 core staight needles, carry out as required the peripheral interface design.
Watchdog circuit 3: because the residing running environment condition of work of data server is often very abominable, so that being subject to various electromagnetism thousand inevitably, microprocessor system disturbs, cause program " to fly ", enter " endless loop ", thereby make system out of control, the data server cisco unity malfunction.
Program " is pulled back ", the effective ways of breaking away from " endless loop " are to adopt hardware " house dog " circuit, this circuit is used for monitoring the running status of main program, when main program sinks into endless loop because of interference, and when surpassing the delay requirement of watchdog circuit regulation running time, circuit just sends reset signal, includes the main program of single-chip microcomputer in normal running status.
The application of employing integrated monitoring chip had both reduced the complexity of SCM peripheral circuit, had reduced again the quantity of element.
Photoelectric isolation module 5 is a photoelectric coupling circuit: reliable for further guaranteeing security of system, guarantee the reliability of transfer of data under strong electromagnetic interference environment, and the measuring junction of data server adopts photoelectrical coupler to carry out electrical isolation.Consider the transmission speed of system, adopt high-speed photoelectric coupler.
Interface module 6: in the data server application system, RS-485 half-duplex asynchronous communication bus is used between centralized control hinge (data server) and the decentralized control unit.
When using the RS-485 bus, if design circuit in the usual way simply may have following two problems to occur in Practical Project.The one, the integrity problem of communication data transmitting-receiving; The 2nd, under the multi-computer communication mode, the fault of a node (as crashing) tends to so that the communications framework of whole system collapses, and brings difficulty for the investigation of fault.The RS-485 interface chip damages all might being subject to the impact of static in transit of use, welding or equipment, be set up in attack that outdoor use occasion, interface chip and even whole system also might cause thunder and lightning, select the chip of antistatic or anti-lightning can effectively avoid this type of loss at transmission line
For the problems referred to above, the present invention has taked concrete corrective measure to the software and hardware of RS-485 bus, impact that not only can anti lightning but also can bear static discharge up to 8kV.
The programming of software:
Software programming also has a significant impact the reliability of product.Because 485 buses are communication buss of asynchronous half-duplex, in some moment, bus only may present a kind of state, so this mode generally is applicable to main frame to the inquiry mode communication of extension set, must there be an equipment that is in all the time the main frame status patrolling and examining other extension set on the bus, coordinates the time sharing shared of bus so need to formulate the rational communication protocol of a cover.What the present invention adopted is the data packet communication mode.Communication data is that framing becomes bag to send, and every bag data all partly are comprised of guidance code, length code, address code, command code, content, check code etc.Wherein guidance code is for each wraps the seeker of data synchronously; Length code is the total length of these bag data; Command code is that main frame is to the control command of extension set (or extension set is replied main frame); Address code is the machine address number of extension set; " content " is the various information in these bag data; Check code is the check mark of these bag data, can adopt parity check and the different modes such as verification.
By software and hardware co-treatment of the present invention, the reliability in the application system of the present invention improves, under common environmental condition, and continuously start in 24 hours, the communication of system is in normal condition all the time, and overall performance satisfies the needs of field engineering.
