Problems solved by technology

[0006] The purpose of the present invention is to solve the problem that the program responds laggingly to network status changes (network disconnection and network IP changes), and in combination with the above background and requirements, a method for self-adaptive monitoring of the network status of the electric hanging platform data acquisition system is proposed. The built-in system command of the Linux system can detect the network status, and when a fault is found, restart the network dial-up program to restore the network

Embodiment Construction

[0028] The principles and features of the present invention will be described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0029] In this example, the N32926 of Xintang Company is used as the main control chip of the embedded system, the Quectel EC20 is used as the 4G module, and the Linux kernel version is 2.6.35.

[0030] Such as figure 1 Shown, the present invention is based on the self-adaptive monitoring method of network status of electric hanging basket data acquisition system of embedded Linux, it is characterized in that, comprises the following steps:

[0031] Step 1: Create a file used to mark the network as uninitialized, prompting that the network link of the external program is not initialized;

[0032] Step 2: Run the network dial-up program to initialize the network;

[0033] Step 3: Monitor the abnormal state of t...

Abstract

The invention discloses a network condition self-adaptive monitoring method for an electric hanging basket data acquisition system, which comprises the following steps of: 1, creating a file for marking that a network is not initialized, and prompting that an external program network link is not initialized; step 2, running a network dialing program, and initializing a network; step 3, monitoringthe abnormal state of the network; step 4, deleting files used for marking network condition abnormity and marking network non-initialization; and step 5, carrying out real-time network state testing:step 6, creating a file for marking network condition abnormity, closing the dialing program, restarting the dialing program, and entering the step 3 to continuously monitor the network state. According to the method, the network state is detected through the system command of the embedded Linux system, and when a fault is found, the network dialing program is restarted to recover the network. Ifthe network is disconnected for a long time, the abnormal state of the network can be reported, so that the network program can timely process the abnormal state of the network.

Description

Technical field: [0001] The invention relates to a self-adaptive monitoring method for the network status of an electric hanging basket data collection system, in particular to an adaptive monitoring method for the network status of the electric hanging basket data collection system based on embedded Linux. Background technique: [0002] The electric gondola is a kind of manned and loaded cargo take-off and landing equipment commonly used on construction sites. It can be used to assist high-altitude workers to complete the work of installing glass curtain walls outside the building. A set of electric hanging basket data acquisition system has been developed to upgrade the traditional hanging basket. The system has the function of uploading data through the Internet, and uses a 4G module to connect to the Internet. [0003] Since the construction sites in today's cities are generally in relatively remote places, the mobile network signal is poor and the fluctuation is large; ...
