Problems solved by technology
Due to the problems of scattered branches and difficult maintenance of water intake monitoring points, with the continuous increase of monitoring scale, the workload of inspection and maintenance of monitoring equipment failures is increasing.
At present, there is no fault diagnosis system developed for water intake monitoring equipment. Only manual inspection and manual on-site maintenance methods can be used. The timeliness and economy cannot meet the needs. Affect the implementation of the national water withdrawal red line control strategy and the most stringent water resources management system

Embodiment Construction
[0014] combine figure 1 and figure 2 As shown, the present invention provides a method for grading and diagnosing faults of remote water intake monitoring equipment, including:
[0015] a. Utilize the RTU terminal, GPRS module and monitoring platform that constitute the communication connection in sequence, communicate the flowmeter communication status of the water intake monitoring equipment, the battery power supply status of the flowmeter, the battery power supply status of the monitoring box, the mains power supply status, the output status of the switching power supply and the box The door opening status is transmitted to the RTU terminal respectively, and the RTU performs the first diagnosis on the running status, which constitutes the collection and diagnosis of the first-level fault status;
[0016] Specifically:
[0017] a1. The CPU of the RTU terminal allocates the flowmeter communication status register. The register value indicates whether the communication wit...

The invention discloses a remote water taking monitoring equipment fault grading diagnosis method. The method comprises steps that a, an RTU terminal, a GPRS module and a monitoring platform which are in sequential communication connection are utilized to respectively transmit a flowmeter communication state of water taking monitoring equipment, a flowmeter storage cell power supply state, a monitoring box storage cell power supply state, a commercial power power supply state, a switch power source output state and a box door opening state to the RTU terminal to realize acquisition and diagnosis of a first grade fault state; b, the acquired fault states are sent by the RTU terminal to the GPRS module to realize acquisition of a second grade fault state; c, the acquired fault states are sent by the GPRS module to the monitoring platform, the fault states are gathered and diagnosed by the monitoring platform, and fault diagnosis for data of the GPRS module and the monitoring equipment is further carried out through the monitoring platform to realize acquisition and diagnosis of a third grade fault state. The method is advantaged in that fault maintenance efficiency is actually improved, maintenance cost is reduced, and normal operation of the water taking monitoring system is guaranteed.
Description
technical field [0001] The invention relates to the technical field of remote monitoring of water conservancy information, in particular to a method for grading and diagnosing faults of remote water intake monitoring equipment. Background technique [0002] It is well known that online monitoring of water intake for water resources is the key technical means for the most stringent water resource management, and is generally used for monitoring water intake in industrial production, domestic water, irrigation, etc. The water intake monitoring system for water resources mainly includes metering equipment, power supply equipment, telemetry terminals, wireless transmission, and monitoring platforms. Collection and analysis of monitoring data. [0003] To ensure the reliability and accuracy of water intake monitoring, the premise is that the monitoring equipment itself can operate normally, and timely detection and diagnosis of faults are the basis for ensuring the normal operat...
