Problems solved by technology

[0004] RTU manufacturers mostly develop RTUs with strong versatility. In terms of hardware, they mostly use a single signal interface and support a single communication protocol; in terms of business (such as control), they lack professionalism and industry intelligence. Set up some simple analysis logic and PID control program based on manual experience

Embodiment 1

[0022] Intelligent remote monitoring, early warning and control terminal, including processing module, management module, power supply module, transmission module, and expansion module; management module, power supply module, transmission module, and expansion module are respectively connected with processing module; management module is connected to power supply through bus The modules are connected.

[0023] The management module includes a storage chip; the storage chip can be configured with a 2M-64M-bit flash memory chip, which is used to store up to one year of historical data.

[0024] The transmission module includes an isolated interface, a digital input interface, a digital output interface, and an analog input interface.

[0025] The expansion module can expand the GPRS expansion board, NB-IoT expansion board, LoRa expansion board and MBus expansion board.

[0026] The transmission module supports GPRS / 4G / MBUS / RS485 communication methods and protocols; supports wir...

Embodiment 2

[0032] Such as Figure 4 As shown, when the intelligent remote monitoring and early warning and control terminal is controlled by a single unit, and the device data parameters are found to be abnormal, the transmission module obtains the relevant data of the sensing device and transmits it to the processor in the processing module. The hydraulic model and equipment characteristic curve simulation operation data are compared with the trigger conditions of the control strategy, and the appropriate control strategy is selected and issued and controlled.

Embodiment 3

[0034] Such as Figure 5 As shown, when multiple intelligent remote monitoring and early warning and control terminals are jointly controlled, and multiple terminals are connected to the system platform through the network, when the real-time parameters of each terminal are collected, the system platform will analyze and combine the hydraulic model control strategy, and based on The parameters collected in real time are comprehensively analyzed and judged to form a control strategy to jointly control two or more devices (water pumps, valves, etc.), and the platform strategy can also be executed after manual confirmation.

Abstract

The invention provides an intelligent remote monitoring early-warning and control terminal referred to as an intelligent RTU for short. The intelligent RTU comprises a processing module, a managementmodule, a power module, a transmission module and an extension module, wherein the management module, the power module, the transmission module and the extension module are connected with the processing module respectively; and the management module is connected with the power module through a bus. The intelligent RTU supports multiple signal forms, such as an analog quantity, a switching quantityand a digital quantity, supports multiple communication modes and protocols, such as GPRS, 4G, MBUS and RS485 and also supports a wireless network, an Ethernet optical fiber finite network and othertransmission modes. Through the intelligent RTU, the unity of a signal interface and a communication protocol of hardware and the specialty and intelligence of functional application service management are realized.

Description

technical field [0001] The invention relates to the field of water conservancy equipment, and more specifically, to an intelligent remote monitoring, early warning and control terminal. Background technique [0002] When the domestic RTU (remote terminal control system) products started, the general functions were simple data collection and simple switch control, and the data processing capacity was limited. The new generation of network and communication technology has improved the performance and wider application of RTU. Today, with the development of intelligence, RTU technology is also developing in the field of intelligence, and plays a key role in industrial automation and intelligence. [0003] In terms of technical solutions, RTU has the capabilities of analysis, judgment, control, and transmission, and is also more intelligent in terms of networking, deployment methods, and master-slave switching. It can automatically judge whether the acquired data needs to be re...
