Multipurpose low-power control device and multipurpose low-power control method for dynamic characteristic tests

Abstract

The invention discloses a multipurpose low-power control device and a multipurpose low-power control method for dynamic characteristic tests. The multipurpose low-power control device comprises an ARM [advanced RISC (reduced instruction set computer) machine] processor, an OLED (organic light emitting diode) display module, a DDR3 SDRAM (double data rate 3 synchronous dynamic random access memory), an SPI (serial peripheral interface) Flash storage module, an eMMC (embedded multimedia card) storage module, an SD (secure digital) card storage module, a GPS (global positioning system) positioning module, a wire communication module, a wireless communication module, a charge and discharge management module, a power supply module and a peripheral module. Battery charge and discharge can be managed by the charge and discharge management module, and external AC adapter power supply and battery power supply paths can be dynamically switched over according to requirements of systems. The multipurpose low-power control device and the multipurpose low-power control method have the advantages that the problem of poor compatibility of existing master control and data acquisition cards can be solved by the aid of the multipurpose low-power control device and the multipurpose low-power control method, and the multipurpose low-power control device and the multipurpose low-power control method are conveniently compatible with existing high-precision universal data acquisition cards.

Description

technical field [0001] The invention relates to control technology, in particular to a multipurpose low power consumption control device and method for dynamic characteristic testing. Background technique [0002] With the rapid development of current science and technology, more and more attention has been paid to the use of experiments to verify theoretical models in the fields of automobile engineering and national defense technology. Products, so the demand for dynamic characteristic testing is also increasing. The current dynamic characteristic test system on the market mainly adopts PC analysis software + data acquisition system mode, such as designing a test module with a USB interface to cooperate with a PC to form a complete dynamic test system; there are also designed acquisition boards with a PCI or PCIe bus interface , and built it on the PC motherboard, so that the PC has the ability to test the dynamic characteristics of the system. The common feature of thes...

AI Technical Summary

Problems solved by technology

The common feature of these solutions is that they are large in size, poor in flexibility, and not convenient for personal portability and real-time analysis of on-site measurement data; the existing integrated system dynamic characteristic tester is a special device developed by a related company, which is compatible with a general-purpose data acquisition card. Poor compatibility, not conducive to standardization or system integration
