On the same CAN network of the quantity of described data acquisition module for being no more than 16.
Beneficial effect:
1, the utility model has adopted multichannel data acquisition module, each data acquisition module can gather arbitrarily different types of several sensor signals, data acquisition module as one independently CAN node carry on the CAN bus, the data that gather are sent on the CAN bus after with the packing of CAN message format.Like this, no longer need every kind of different sensor of output signal is adopted different acquisition modules, greatly reduced the complexity of grid, improved bus efficiency and load factor.
2, by configuration and the demarcation of host computer monitoring platform to the data acquisition module, applicable to the car load electric system, comprise the ECU (Electrical Control Unit) signal monitoring requirements such as engine, variator, retarder, ABS system.Therefore has the versatility of certain degree.
Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the basic block diagram that the utility model specifically reflects data acquisition module.
Fig. 2 is that the signal monitoring system externally sends CAN message information form.
Fig. 3 is testing table signal monitoring entire system Organization Chart.
Embodiment
The automobile electronic control unit testing table signal monitoring system based on the CAN bus as shown in Figure 1, comprise that type is a plurality of sensors, host computer monitoring platform, data acquisition module and the CAN address card of analog quantity, switching value, pulsed quantity signal, the host computer monitoring platform connects the CAN address card, data acquisition module comprises the multi pass acquisition passage, and each road acquisition channel is respectively applied to gather the dissimilar sensor signal.Each data acquisition module contains maximum 16 road acquisition channels, 16 road acquisition channels can non-interferingly be configured to the different sensors type, be particularly useful for multi-channel measurement, no longer need every kind of different sensor of output signal is adopted different acquisition modules, reduced the system complex degree.
Fig. 1 is take gearbox testrigs as example, and the key property of variator is determining that this signal monitoring system has contained I/O rotating speed, I/O torque, system's main oil pressure, gear-shifting actuating mechanism driving signal and oil pressure, oil sump oil temperature, converter lockout point rotating speed, the flow of hydraulic circuit, the multi-class signal data acquisition such as gear, failure message of working.Data acquisition module as a CAN node independently, sends to the data that gather on the CAN bus in system in real time.
As shown in Figure 3, the data acquisition module is configured and demarcates by the RS232 port at the host computer monitoring platform, signal by the required collection of each channel selecting is respectively digital signal, simulating signal or pulse signal, again according to the sensor parameters index, fill in voltage range and the actual physics value scope of gathering at the upper computer software interface, after the full detail configuration is complete, clicks " affirmation " acquisition module is finished calibration process.Both without potentiometer, also without wire jumper, therefore need not to do any adjustment at hardware in the testing table signal monitoring system.
Acquisition module has versatility, supports expansion in the signal monitoring system, but 16 identical data acquisition modules of carry on the same CAN network, and therefore measuring overall channel can reach 256 the tunnel.Can read simultaneously the data of whole 256 passages by the host computer monitoring platform, both simplify serial ports multi computer communication line, simplify again the software communication agreement.To not computed occasion, the demonstration node that available liquid crystal display and keyboard form is as the host computer administration module.Host computer passes through the CAN address card to data acquisition module, variator electric-control system, and the CAN information that carry each node in same CAN network sends receives, processes, shows and storage.
