The amount of the keypresses is 32, the operating states can be displayed through the colors of indicator lights of the 32 keypresses, and also date can be transmitted to an upper computer through the 32 keypresses; and each indicator light can display three colors, and each color represents a state. The utility model has the advantages that centralized control can be achieved through PROFIBUS-DP, and the data transmission is stable.
Description
Technical field
The utility model relates to the technology of instrument and meter field, is the operating unit that adopts the PROFIBUS-DP industrial field bus.
Background technology
At present, the PROFIBUS-DP bus control system is in the widespread use of China's automatic field, it adopts digital signal to replace simulating signal, can realize a plurality of signals of transmission on a pair of cable, again for a plurality of equipment provide power supply, so both simplied system structure, economize on hardware equipment can also reduce stube cable and installation simultaneously, therefore, seem particularly important for intelligence instrument or equipment development PROFIBUS-DP communication interface.
Past production line operation platform all adopts the button of dispersion, is connected by electrical wiring on the remote I/O station of controller such as PLC, and the I/O station is received operative employee's push button signalling and output indicator signal respectively by input/output module.Its shortcoming: the circuit complexity, every production line all will show the button and the pilot lamp of design operation platform, and the equipment construction amount is very big, also need manual debugging, and once on-the-spot increase function button or the pilot lamp of needing revises very trouble, also need perforate in addition on operator's console.
Summary of the invention
But the purpose of this utility model provides a kind of PROFIBUS-DP of employing industrial field bus centralized control and the stable operating unit of data transmission.
For achieving the above object, the utility model is achieved through the following technical solutions:
Operating unit, comprise keyboard, photoelectric isolation module, photoelectricity isolation drive module, microprocessor, storer, SPC3 chip, this device is PROFIBUS-DP industrial field bus product, be provided with control CPU and communication two microprocessors of CPU, keyboard connects control CPU by photoelectricity isolation drive module; Control CPU is connected with communication CPU, is provided with dual port RAM between two CPU; Communication CPU connects the SPC3 chip, finishes interconnected with the PROFIBUS-DP interface by the SPC3 chip.
Described control CPU and communication CPU all adopt the STC89C516 single-chip microcomputer.
Described keyboard comprises 32, and keyboard can pass through the color display operation state of pilot lamp, or transmits data by 32 keyboards to host computer.
Described control CPU connects 16 digital-quantity input terminal by photoelectric isolation module, connects 16 digital quantity lead-out terminals by photoelectricity isolation drive module.
Compared with prior art, the utility model has the advantages that:
But adopt PROFIBUS-DP industrial field bus centralized control, and data transmission is stable.This equipment is furnished with 32 operation push-buttons, and each button has the three-color LED pilot lamp can show different conditions, and button freely defines, and it is convenient to revise, and DP line one line is finished connection, does not need huge I/O and signal wire.Need not debugging and school line, save lot of manpower and material resources, reduce failure rate.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
See Fig. 1, a kind of operating unit, comprise keyboard, photoelectric isolation module, photoelectricity isolation drive module, microprocessor, storer, SPC3 chip, this device is provided with control CPU and two microprocessors of communication CPU, and keyboard connects control CPU by photoelectricity isolation drive module; Control CPU and communication CPU all adopt the STC89C516 single-chip microcomputer of anti-electromagnetic interference (EMI), and it has low in energy consumption, integrated level height, characteristics such as easy compatibility.Between control CPU and communication CPU, be provided with the dual port RAM that is used to store data.Communication CPU connects the SPC3 chip, finishes interconnected with the PROFIBUS-DP interface by the SPC3 chip.
Keyboard comprises 32, has input/output function, can pass through the color display operation state of the pilot lamp of 32 keyboards, also can import data to main website by this keyboard simultaneously.Each pilot lamp can show 3 kinds of colors, and each color is represented a kind of state.
Control CPU connects 16 digital-quantity input terminal by photoelectric isolation module, connects 16 digital quantity lead-out terminals by photoelectricity isolation drive module.
The SPC3 chip is the PROFIBUS specialized protocol chip of SIEMENS exploitation, and there is microcontroller its inside, and the integrated complete agreement of PROFIBUS-DP, and have the INTEL microcontroller interface conveniently is connected with single-chip microcomputer.In addition, the RS485 interface circuit design of SPC3 will be considered the interference from zero line, therefore needs to add photoelectricity isolation drive module between the two.
For realizing the needs of peripheral equipment control, control also connects 16 digital-quantity input terminal and 16 digital quantity lead-out terminals by photoelectric isolation module respectively with CPU.
This operating unit has following function: according to the PROFIBUS-DP communication protocol standard, carry out real-time Communication for Power by RS485 interface and host computer; Baud rate self-adapting, maximum baud rate are 12M; Have 32 tri-colour LED keyswitches, can be whether according to the reservation of its color show state of configuration settings and feeler switch, each switch can be configured to be with self-locking and two kinds of working methods of non-self-locking; 16 digital quantity inputs, 16 digital quantity outputs; Tributary address manually is set.
