Accompanying drawing explanation
Comprising accompanying drawing is further understand the utility model for providing, and they are included and form a application's part, and accompanying drawing shows embodiment of the present utility model, and plays the effect explaining the utility model principle together with this instructions.In accompanying drawing:
Fig. 1 is the schematic diagram of the first embodiment of checking weight weigh system of the present utility model.
Fig. 2 is the schematic diagram of the second embodiment of Weighing module system of the present utility model.
Embodiment
With detailed reference to accompanying drawing, embodiment of the present utility model is described now.
The utility model is a kind of checking weight weigh system, it checking weight weigh comprising master station, master station is converted to the modular converter of Modbus and be connected with Modbus.Checking weight weigh system architecture of the present utility model is simple, and it realizes telemonitoring to checking weight weigh and control by master station, can carry out the collection of weighing data simultaneously; It is by arranging modular converter, adds the kind of the interface controlling checking weight weigh.
Fig. 1 is the first embodiment of the present utility model, and described master station 1 is a Profibus master station.Described modular converter 2 turns Modbus module for Profibus.The quantity one_to_one corresponding of described modular converter and checking weight weigh.
A terminal resistance 4 is provided with between described Profibus master station 1 and modular converter 2.By arranging terminal resistance 4, can the interference of anti-stop signal.
Described Profibus master station 1 with between modular converter 2, between modular converter 2 with checking weight weigh 3 for cable is connected, described cable is shielded cable.In the present embodiment, described checking weight weigh 3 is the instrument of checking weight weigh.
Fig. 2 is the second embodiment of the present utility model, and described master station 11 is an Ethernet/IP master station, the quantity one_to_one corresponding of described modular converter 12 and checking weight weigh 13.A router five is provided with between described Ethernet/IP master station and modular converter.
Described modular converter 12 turns Modbus module for Ethernet/IP.
In the above two embodiments, described modular converter (2,12) with checking weight weigh (3,13) for cable connects between, described cable and modular converter (2,12) and checking weight weigh (3,13) be respectively serial ports connect, described serial ports is RS485 or RS232.
The weighing data of the checking weight weigh (3,13) that described master station (1,11) obtains is floating number.Because weighing data is floating number, so directly calculation process can be carried out.
Checking weight weigh system can be connected in various field bus system.Formulate the communication protocol being applicable to checking weight weigh system, master station (1,11) initiatively initiates the instruction reading or write register, checking weight weigh (3,13) as slave station, the information that passive reply master station (1,11) needs also does corresponding response.According to on-the-spot practical application, determine that master station (1,11) reads the frequency of register and corresponding serial communication speed.In the present embodiment, register is located in modular converter (2,12) and master station (1,11).
Master station (1,11) reads the content of register and comprises: checking weight weigh system running state, whether prepare, error code, current production formulation data, single bag weight, the information such as statistics program.Master station (1,11) repeats to read register address, master station (1 with certain frequency, 11), after receiving master station (1,11) inquiry instruction, reply corresponding registers content is carried out immediately, thus make master station (1,11) obtain the real-time status of checking weight weigh system.
