Embedded type intelligent system for hydrology and water resource monitoring

Abstract

The invention provides an embedded type intelligent system for hydrology and water resource monitoring.The system is characterized by comprising a driving layer, a service layer, a data communication management layer and a user interaction layer; the driving layer is located at the lowermost layer of the system, provides sensor data for the three layers located above and serves as an interface for data transmission conducted by an external equipment module; the service layer is used for achieving sensor data acquisition and storage by calling a sensor read-write interface of the driving layer according to operating parameter configuration of the system; the data communication management layer is used for conducting packing and unpacking on a protocol and calling data transmitted and received by a transmission module interface; the user interaction layer is used for interact a driving processing interface with external input / output equipment.By means of the embedded type intelligent system, the coupling degree of the system can be lowered, and cohesivenss of the system is enhanced.

Description

technical field [0001] The invention belongs to an intelligent equipment management system in the water conservancy industry, in particular to an embedded intelligent system for monitoring hydrology and water resources. Background technique [0002] RTU controllers are commonly used in the existing water conservancy industry. They are characterized by wired transmission and independent work. It is difficult to form a network for communication. Due to the limitation of wired methods, it is impossible to realize multi-sensor distributed collection and network management, and its application is difficult to expand. , the main disadvantages: cables must be pulled, there is no interconnection between RTU and RTU, and the number of sensors connected to RTU is limited; secondly, each RTU has a GSM module, and sensor information cannot be obtained when the GSM module fails or the SIM card fails. Main disadvantages: RTU failure, normal sensor, interruption of data collection, personn...

[0002] RTU controllers are commonly used in the existing water conservancy industry. They are characterized by wired transmission and independent work. It is difficult to form a network for communication. Due to the limitation of wired methods, it is impossible to realize multi-sensor distributed collection and network management, and its application is difficult to expand. , the main disadvantages: cables must be pulled, there is no interconnection between RTU and RTU, and the number of sensors connected to RTU is limited; secondly, each RTU has a GSM module, and sensor information cannot be obtained when the GSM module fails or the SIM card fails. Main disadvantages: RTU failure, sensor is normal, and the data collection is interrupted. Personnel must be present to replace the RTU. If the RTU is connected to the Internet, another RTU can be connected to the sensor again to obtain the data of the sensor.

In addition, the existing equipment sensors are all wired transmission, and the RTU cannot obtain the health status of the sensors. The equipment sensors need to be maintained separately, and the operation and maintenance costs are relatively high. The main disadvantages: the RTU is normal, the sensor is faulty, and the maintenance personnel may not be able to find the sensor problem at the first time.

Based on the above, the existing RTU usage form can no longer meet the application of modern smart water network
