Ship-lock multi-channel water level measuring system and filter method thereof

Abstract

The invention discloses a ship-lock multi-channel water level measuring system and a filter method thereof. The ship-lock multi-channel water level measuring system comprises a multi-water level sensor, a data acquisition module, a remote motoring PC (Personal Computer) machine, a GSM (Global System of Mobile communication) module, a communication network, and the like. The ship-lock multi-channel water level measuring system is characterized by monitoring the water levels of multiple measurement points, namely ship-lock upstream and downstream, a lock chamber, and the like, in real time by taking a singlechip as a lower microcontroller and using a high-accuracy A / D (Analog to Digital) convertor, packing and reforming multipath data and then remotely transmitting to an upper monitoring PC machine by utilizing a 485 bus to display the water level values of the measurement points in real time, transmitting water level information to a certain mobile phone subscriber through a GSM short message module and a wireless network thereof and supporting the mobile phone subscriber to actively take the water level values of the measurement points at any time by utilizing the GSM network. The ship-lock multi-channel water level measuring system disclosed by the invention is easy to realize the advantage of absolute stability by adopting an FIR (Finite Impulse Response) filter based on the median filter of the singlechip and has the advantages of low cost, high accuracy and anti-interference capacity and friendly human-computer interaction.

Description

technical field [0001] The invention relates to a measurement system, in particular to a ship lock multi-channel water level measurement system and a filtering method. Background technique [0002] The real-time monitoring of the water level of the lock station is an inevitable requirement for the operation management of the lock and the safe navigation of ships. Ship lock dispatchers must always pay attention to changes in the water level upstream, downstream, and in the lock chamber. Accurate and reliable water level data make it possible for ships to automatically pass through the lock, thereby greatly reducing the difficulty of ships passing through the lock and the work intensity of ship lock dispatchers. At the same time, the ship lock It is also very necessary for the friends of the boat people to keep abreast of the changing upstream and downstream water level information in a timely manner, so that they can take the initiative to make a choice whether to set sail or...
