Engineering monitoring low-power-consumption single-point transmission type acquisition system and method

Abstract

The invention discloses an engineering monitoring low-power-consumption single-point transmission type acquisition system and method. The device comprises a control module, a power supply module, an external clock module, a survey signal pick-up module and a wireless communication module; the control module comprises a processing chip, a diverter switch, a watchdog circuit, an internal crystal oscillator and a power supply switch; the wireless communication module is a 3G / 4G wireless transmission module. Through cooperation of the external clock module and the 3G / 4G wireless transmission module, power supply of periphery equipment is reduced in the working state of not acquiring data, the endurance time is prolonged, an intermediate node of data acquisition between the acquisition system and a server is avoided, measure point deployment is not influenced by power supply, channel, distance and the like, the deployment mode is flexible, and the hardware cost is reduced. The engineering monitoring low-power-consumption single-point transmission type acquisition system and the engineering monitoring low-power-consumption single-point transmission type acquisition method can be widely applied to the field of engineering monitoring.

Description

technical field [0001] The invention relates to the field of engineering monitoring, in particular to an engineering monitoring low-power single-point transmission acquisition system and method. Background technique [0002] Existing engineering inclinometer data, especially foundation pit engineering which is widely used. Active inclinometers are mostly used to collect data manually, and the original data is exported back to the resident, obtained through the supporting calculation software of the inclinometer or the calculation table prepared by the user according to the formula, and the data report is issued by manual processing. In the application of fixed inclinometers in mine slopes and dams, smart inclinometers are mostly used, which directly output 485 signals and forward them to the data center through 4G signals. Most of the automatic acquisition modules suitable for foundation pits that have appeared in recent years are in the engineering test stage, and it is ha...

Problems solved by technology

[0003] The existing engineering inclinometer data is automatically collected, and the monitoring mainly adopts the intensive data collection mode, that is, multiple measuring point terminals are used to transmit the data to the hub or the collector through wired or wireless means, and then the collector transmits the data to the data server; this method exists The following disadvantages: (a) The deployment of the measuring point terminal is restricted by the acquisition instrument, which has limitations such as communication distance, power supply, and number of channels, such as acquisition terminals using communication modules such as 433M wireless modules and 2.4G wireless modules; (b ) Due to the influence of the communication distance between the measuring point terminal and the collector; resulting in waste of the functions of the collector; (c) Since the collector belongs to intensive transmission and is a high-energy-consuming device, it needs to be configured separately for power supply, which is not conducive to the installation of the project site ; Or additional circuits for low power consumption need to be set up, which is not conducive to hardware cost control in large-area deployment
