Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail, please refer to Figure 1 to Figure 3 .

[0026] Such as figure 1 As shown, the engine parameter acquisition box is composed of a main control module 1 , a power module 2 , a socket board part 3 and a base part 4 .

[0027] Such as figure 2 As shown, the main control module includes a resistance signal conditioning circuit 101, a frequency signal conditioning circuit 102, an RS232 signal interface circuit 103, an RS422 signal interface circuit 104, a channel selection circuit 105, a programmable gain circuit 106, an AD conversion circuit 107, a CPLD circuit 108 and CPU circuit 109. The resistance signal conditioning circuit 101 is connected with the channel selection circuit 105 to condition the resistance signal provided by the engine sensor. Its core device is the constant current source chip AD694BQ, the input voltage is 0V~2.5V and the corresponding output curre...

Abstract

The present invention relates to an engine parameter collection box. The engine parameter collection box comprises a main control module, a power module and a plug board part, the main control moduleis connected with the power module, the power block is connected with the plug board part, and the main control module can achieve centralized collection of multiple types of signals of an engine andcan convert the signals to RS422 bus signals for output. The engine parameter collection box can effectively reduce the errors caused by long-distance concentration of source end signals on the engineand can ensure the real and effective signals.

Description

technical field [0001] The invention relates to an engine parameter acquisition box, in particular to an engine parameter acquisition box for real-time acquisition and conversion of engine signals. Background technique [0002] In light and small aircraft engine status monitoring, the engine signal is generally connected to the corresponding acquisition device for acquisition, and there is no equipment specifically for engine signal acquisition. Due to the different collection and processing methods of different devices, the parameter values ​​of the same signal after collection are inconsistent, and even there are large errors; the same signal is connected to different devices for collection, which will also lead to abnormal situations such as complex wiring on the machine and signal load impedance mismatch. Contents of the invention [0003] Purpose of the invention: [0004] An engine parameter collection box is provided, which collects and processes light and small ai...
