Embodiment 1

[0033] like figure 1As shown, this embodiment provides a comprehensive data acquisition device, including a power supply module, a data acquisition module, a data processing module, a communication module and a storage module; the storage module is connected to the U disk / hard disk interface provided on the data processing module.

[0034] The power module includes three power modes of DC5V, AC220V and DC110V, which respectively support power supply through an external power bank when there is no power supply, and AC220V and DC110V power supply.

[0035] Data processing module and data acquisition module hardware can adopt CPU+FPGA framework, single-chip FPGA band processor core framework etc. NI-RT real-time operating system, VXworks real-time operating system, QNX real-time operating system and other real-time operating systems, the RTLinux operating system is used in this embodiment. The train integrated data acquisition device uses the RTLinux operating system to open sou...

Embodiment 2

[0046] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the data acquisition device is connected with an inclination tester for testing the inclination, a GPS positioning module for obtaining a real-time position, a wireless network card, and a touch screen.

[0047] The setting of the inclination tester and the GPS positioning module can test the inclination angle of the train and obtain the real-time GPS position information data of the train. The wireless network card is used to transmit data to the remote server and remotely control the device through the leased network of the operator; if the collected data is saved, it can be saved to the remote server through the wireless network card, and 3G / 4G / 5G wireless network card, this embodiment selects 4G wireless network card. The touch screen is used to set the function of the device, display the status information of the device and collect and test the main data information, such as ...

Embodiment 3

[0050] The difference between this embodiment and Embodiment 2 is that it also includes a trigger interface for sending and receiving trigger signals for data trigger synchronous acquisition; there are two types of trigger interfaces; The interface sends a trigger signal to the outside; one is a slave trigger interface, which has a slave trigger working mode and receives a trigger signal sent by an external device, and the external device is another comprehensive data acquisition device or other devices. This embodiment includes two trigger interfaces: a master trigger interface TRIG1 and a slave trigger interface TRIG2.

[0051] like Image 6 As shown, when multiple devices perform synchronous acquisition, there are three ways to apply the trigger interface.

[0052] like Image 6 Mode 1: One device is the master, sending trigger signals through TRIG1, and other devices are slaves, receiving trigger signals through TRIG2, so that multiple devices can perform synchronous acq...

Abstract

The invention discloses an integrated data collector and a data consistency verification and test method thereof. The integrated data collector comprises a power supply module, a data collection module, a data processing module, a communication module and a storage module; the data collection module comprises an FPGA module, an AD module and a sensing element which are connected successively; theFPGA module is provided with MVB and / or WTB network data collecting interface(s); the communication module comprises an Ethernet / WIFI control interface connected with a peripheral PC and / or mobile terminal to realize control, configuration and data interaction of the collector; the storage module is connected with a U-disk / hard-disk interface in the data processing module; and the data processingmodule is connected with an Ethernet monitoring port for monitoring real-time Ethernet, collecting data of a train and parsing protocols. The collector can be used to collect different types of data,is small in size, portable, and capable of remote control, long-time data test and recording.

Description

technical field [0001] The present invention relates to the technical field of detection equipment, and more specifically, to a comprehensive data acquisition device and a data consistency verification test method thereof. Background technique [0002] With the sharp increase in the demand for on-site testing in recent years, in order to study the reliability, service performance and service life of key equipment and components of trains, it is required to collect as many data as possible, such as converter voltage and current data, train network Communication data, train vibration, inclination, acceleration data, train torque, speed data, environmental data, line conditions, geographic location data, etc. At present, there are TCN protocol analyzers, power analyzers, torque speed test devices, vibration test devices, etc. on the market, all of which only collect and test a single data of the train, and are bulky and have a single power supply method, and do not support long...
