Abstract
The utility model relates to a motor control loop, in particular relates to a novel motor control loop applied to a protein production DCS system, and belongs to the mechanical and electrical technical field. According to the novel motor control loop applied to the protein production DCS system, motor protectors and gateways are selected as information acquisition hardware; data of a motor are collected in a MODBUS protocol mode and are uploaded to the gateways through communication lines; and the gateways are adopted to convert MODBUS protocol into Siemens PROFIBUS protocol and are connected with a PLC, such that the data of the motor can be collected, wherein the data are adopted as protection data of the motor. The motor control loop comprises a field control circuit and a field signal circuit; the motor control loop controls the motor; and the field signal circuit transfers information to the PLC through the motor protectors and the communication lines. The novel motor control loop applied to the protein production DCS system is advantageous in simplicity in construction, wiring and installation, reduced number of hardware devices and used control cables and decreased investment cost; and with the novel motor control loop adopted, investment can be saved by 40%.
Description
Technical field
The utility model relates to a kind of Motor Control loop, particularly relates to a kind of novel Motor Control loop that is applicable to protein production DCS system, belongs to the mechanical ﹠ electrical technology field.
Background technology
In recent years; newly-built soybean protein isolate industry has further improved the factory integrated automation level; particularly the control mode that the control of motor is proposed to be fit to own factory realizes exchanges data and protection control between each equipment equipment to enhance productivity and automatization level.Soybean protein DCS system adopts advanced, suitable, effective professional computational methods realize real time information monitoring and the control automatically of whole process of factory production, and the while has been improved the equipment reliability of operation again.It is for the operator of factory provides truly, reliable real-time running data, for enterprise provides science, economic index accurately.But the problem of the Motor Control loop of protein production DCS system existence at present is: digital module and the analog module that will use a large amount of PLC in the control circuit, need to use auxiliary equipment such as a large amount of current sensors, voltage sensor, and the circuit investment is big, the fault point is many.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of technical scheme of the novel Motor Control loop that is applicable to protein production DCS system is provided at the deficiencies in the prior art, this technical scheme can reduce the hardware device use amount, reduce investment, reach the reliability that improves the motor service data, authenticity and the purpose of monitoring property in real time.
For achieving the above object, the technical scheme that the utility model adopts: a kind of novel Motor Control loop that is applicable to protein production DCS system, it is characterized in that, it comprises by selecting for use motor protector, gateway as information gathering hardware, and gathers motor data by the MODBUS protocol mode and be uploaded to gateway through communication line; Use gateway to be converted to the SIEMENS PROFIBUS agreement and be connected to the collection that PLC carries out motor data, as the protected data of motor; The Motor Control loop comprises field control circuit and on-site signal circuit, and the Motor Control loop is controlled motor, and the on-site signal circuit carries out the information transmission through motor protector and communication line and PLC.
The hardwire mode is adopted in the motor start and stop control of described PLC, guarantees operation stability of equipment.
The beneficial effects of the utility model: the wiring of this construction of cable run is installed simple and easy, reduces hardware facility and control cable consumption, reduces cost of investment, saves investment 40%.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
A kind of novel Motor Control loop that is applicable to protein production DCS system as described in Figure, it is characterized in that, it comprises by selecting for use motor protector 3, gateway 2 as information gathering hardware, and gathers motor data by the MODBUS protocol mode and be uploaded to gateway 2 through communication line 6; Use gateway 2 to be converted to the SIEMENS PROFIBUS agreement and be connected to the collection that PLC1 carries out motor data, as the protected data of motor; The Motor Control loop comprises field control circuit 4 and on-site signal circuit 5, and the Motor Control loop is controlled motor, and on-site signal circuit 5 carries out the information transmission through motor protector 3 and communication line 6 with PLC1; The hardwire mode is adopted in the motor start and stop control of described PLC1, guarantees operation stability of equipment.
Operation principle of the present utility model is: PLC1 uses communication lines 6 to be connected in parallel to gateway 2; motor protector 3 to gateway 2 uses a communication line 6 to be connected in parallel; carry out the collection of every protection information by PLC1, Information Monitoring is understood image data by software and is used.This mode has significantly reduced the control line use amount, and power distribution cabinet making simultaneously and circuit are arranged simply attractive in appearance.Kept remote place control function in the control loop, SB1 and the start and stop of SB2 control motor are partly used in field control, and LP1 shows motor local runtime state, and LP2 shows on-the-spot motoring, and LP3 shows the fault alarm state.On-the-spot and DCS control can be switched mutually by on-the-spot change over switch SB3.The on-the-spot button SB3 that selects possesses preferential selection control simultaneously, has guaranteed the fail safe of execute-in-place.2 conversions sent PLC1 to through gateway again after all protection information were logical by the modbus mouth; after information such as motoring, motor fault state, motor running current, working voltage, alarm logging send DCS to, carry out the computing judgement and control required control appliance.By the host computer programming software each state of motor operation is presented on the screen equipment running status is monitored in real time.This motor control system can carry out truer, reliable real-time running data monitoring to single device, can set up accurate, stable protection control to the multiple motors operational system.The wiring of this construction of cable run is installed simple and easy, reduces hardware facility and control cable consumption, reduces cost of investment, saves investment 40%.
Certainly; above-mentioned explanation is not the restriction to utility model; the utility model also is not limited only to above-mentioned giving an example, and the variation that those skilled in the art make in essential scope of the present invention, remodeling, interpolation or replacement also belong to protection range of the present utility model.
