Below, with embodiment the utility model is described in further detail in conjunction with the accompanying drawings:
Fig. 1 is that the circuit of the utility model device is formed block scheme, as shown in Figure 1, the utility model high efficiency smart electromechanical testing platform system comprises PLC control module, sample circuit, interface circuit, computing machine and treats measured motor, sample circuit is electrically connected mutually with sensor, the output of sample circuit is electrically connected mutually with the input of PLC control module, the output of sample circuit is electrically connected with computing machine mutually by interface circuit, computing machine is electrically connected mutually with the PLC control module, and computing machine shows voltage, electric current and the temperature data for the treatment of after measured motor detects.Sample circuit also comprises high-speed data acquisition card and transmitter, and sensor is electrically connected with high-speed data acquisition card mutually by transmitter, and the output of transmitter is electrically connected mutually with the PLC control module.High-speed data acquisition card adopts is based on the pci bus high-speed collection card, and it is current transformer that sensor adopts.
The principle of work of the utility model device is summarized as follows:
Fig. 2 is the electric major loop electrical schematic diagram of the utility model device, Fig. 3 is the PLC control unit circuit electrical schematic diagram of the utility model device, as Fig. 2, shown in Figure 3, the utility model device has electric major loop and PLC control module, with the relevant action of PLC as field controller control automated procedure; Gather voltage, electric current and temperature data with computer platform by high-speed data acquisition card based on pci bus; The monitoring software of writing with VB is gathered next data in order to record and processing on computers.
Electric major loop is the motor control loop of standard.Adopt three-phase fuse cutout QM11 as circuit switching and fuse protection.The usefulness of using 2 A.C. contactor KM11 and KM12 to carry out automatic paraphase and start and stop.The A1 phase of KM11, from suitable for reading through receiving the end opening of the C1 phase of KM11 behind the KM12, the C1 phase of KM11, from suitable for reading through receiving the end opening of the A1 phase of KM11 behind the KM12.Like this when KM11 adhesive KM12 disconnects, the phase sequence of the three-phase supply when providing the phase sequence of three-phase supply of motor M 1 and KM12 adhesive KM11 to disconnect is different.Wherein, contactor KM11 and KM12 can only have one to be in attracting state, are used for realizing the automatic phase sequence switching of three-phase supply, change the motor sense of rotation automatically, save the trouble of artificial conversion phase sequence.At the B1 of QM11 phase end opening, increase the normally closed contact of contactor KM13, can in the needs test, control the adhesive of KM13 coil artificially, the power supply of motor B1 phase is opened circuit, make the fault of motor phase shortage, so that carry out the test of related needs.
Fig. 4 is the sample circuit electrical schematic diagram of the utility model device; As shown in Figure 4, on the three phase supply loop of motor, make Current Transformer TA11, TA12 and TA13, the size of actual current is become in proportion the current signal of 0-5A, this signal passes through the transmitter in the sample circuit again, gives PLC control unit circuit and high-speed data acquisition card with the voltage signal that actual signal becomes in the 0-10V scope.Receiving on the voltage transmitter through insurance FU11, FU12 and FU13 respectively of A1, B1, C1 three-phase, the voltage signal that transmitter becomes actual signal in the 0-10V scope is again given PLC control unit circuit and high-speed data acquisition card.System still gives PLC control unit circuit and high-speed data acquisition card through transmitter with the voltage signal that actual signal becomes in the 0-10V scope with 3 temperature signals.The total loop of PLC control unit circuit is provided with an emergency stop switch JTSB1, when being in an emergency, presses this switch on this device, and the power supply of the control loop that the control motor opens/stops is cut off at once, and is out of service by measured motor.The coil of button XSB22 and A.C. contactor KM13 is connected together, and is used to control the attracting state of KM13, that is, and and artificial the manufacturing by the operation down of measured motor non-full-phase state.The control loop that auxiliary contact and the motor positive and inverse of fuse cutout QM11 open/stop is connected in series, and has only the QM11 closure, and opening/stop control loop could operate as normal.It is just to transport row or counter-rotating operation that rotary switch XSB13 is used for selecting by measured motor.Button XSB11 is used for control and is opened by measured motor/stop, and presses the button XSB11, if XSB13 is selected in 1, then the KM11 coil gets electricly, is just being changeed startup by measured motor; If XSB13 is selected in 2, then the KM12 coil get electric, by measured motor counter-rotating operation.If the startup command of assigning from computing machine is then controlled by the measured motor forward and backward by the attracting state of PLC control unit circuit control K07 and K08 relay and is opened/stop.After K07 connected, the KM11 coil got electric, is just being changeed startup by measured motor; After K08 connected, the KM12 coil got electric, by measured motor counter-rotating operation.The PLC control unit circuit is judged by measured motor ruuning situation according to control and service data, has been judged whether electric fault.If there is voltage, the situation of electric current and temperature anomaly can have corresponding prompt, and can cut off the electricity supply automatically in computing machine, reaches to realize that safeguard protection is by the function of measured motor.
Fig. 5 is the high-speed data acquisition card interface pin figure in the utility model device sample circuit.As shown in Figure 4, the PLC control unit circuit is given digital quantity signal of high-speed data acquisition card by the digital quantity output module automatically after the order that obtains motor and open/stop.Computing machine begins the work of rapid data collection and record after obtaining the signal of this electric motor starting.High-speed data acquisition card adopts the PCI-1711 pci bus high-speed collection card of Advantech.This jig has counter and 12 A/D converters of 3 10MHz, and sampling rate can reach 100KHz, and the record cycle can reach centisecond.Computer monitoring software uses VB to write, and calls the function in the relevant dynamic data chained library of high-speed data acquisition card, realizes the control of integrated circuit board data sampling.Monitoring software will be gathered the data of coming and store according to the form of SQL database, can inquire about at any time.According to the experimentation curve map of the data formation voltage, electric current and the temperature that collect, be convenient to intuitive analysis.
The utility model has adopted high-precision sensor and high-speed data acquisition card, make the precision of data acquisition improve, data acquisition, record cycle weak point are more a lot of soon than the record cycle of other product hundreds of milliseconds, and computing machine can provide more detailed analysis data; Because the watchdog routine of using VB to write, computing machine have friendly operation interface, the user can check the related data of experimentation easily; Simple to operate, generate the experimental data form automatically, for the experimenter has saved the plenty of time, and make report more accurate, avoided artificial mistake.
It is worthy of note; protection domain of the present utility model is not limited to above-mentioned instantiation mode, according to basic fundamental design of the present utility model, as long as those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection domain of the present utility model.
