For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0019] As Figure 1As shown, a water supply engineering system anomaly detection alarm device, comprising an independent detection alarm controller, the independent detection alarm controller is provided with an alarm, the independent detection alarm controller is signal connected with automatic control system, sensor monitoring system, power monitor and monitoring camera, the automatic control system is a multi-channel system, each automatic control system is sequentially numbered, each automatic control system corresponds to a monitoring camera and a sensor monitoring system.

[0020] Based on the above technical features, further, the sensor monitoring system includes but is not limited to water level sensor, flow sensor, pressure sensor and PH sensor.

[0021] Preferably, the automatic control system is provided with a display screen A.

[0022] Further, the monitoring camera and the independent detection alarm controller are provided with a repeater, which enhances the signal transmission between the monitoring camera and the independent detection alarm controller and improves the system stability.

[0023] Further, the independent detection alarm controller is connected with an operator station at the rear end.

[0024] Working principle:

[0025] (1) the automatic control system is numbered, and the independent detection alarm control device records the number of the automatic control system;

[0026] (2) secondly, the automatic control system collects the signals of the sensor monitoring system, and sends the data to the independent detection alarm control device;

[0027] (3) finally, the independent detection alarm control device detects the power failure signal generated by the monitoring camera, power detector and sensor monitoring signal, and alarms when there is an abnormality.

[0028] Figure 2 The sensor monitoring data is uniformly coded, and the specific steps are as follows:

[0029] (1) through the sensor monitoring system, the signals in the water supply system can be obtained in real time, such as water level, flow, pressure, PH value, etc.;

[0030] (2) the signals of the sensor are coded, and different sensors are sequentially superimposed according to the sensor type, sensor data and sensor state, and multiple sensors are combined into a piece of data;

[0031] (3) at the same time, the sensor and the label of the automatic control system are combined and sent to the independent detection alarm control device.

[0032] The automatic control device has a display screen A that shows relevant information. This information, along with power failure signals and equipment operation signals, constitutes a precise and redundant detection system.

[0033] The following table shows the analysis of the causes of alarm anomalies:

[0034] (1) Whether there are any abnormalities in the sensor monitoring signal, power failure signal and the monitoring camera signal. The abnormality is that no signal is detected. If there are abnormalities at the same time, it is that the sensor monitoring signal is abnormal or the power is out of control. If the camera is normal, the system is operating normally, mainly because the camera is a monitoring device that is independent of the automatic control system.

[0035]

[0036] (2) Detect the difference between the current frame and the previous frame of the monitoring camera signal. If the current frame and the previous frame are identified in the same way, the automatic control system is in a stuck abnormal state.

[0037] (3) When the sensor value exceeds or falls below the threshold, an alarm is triggered.

[0038] In summary, this application has a simple structure. In addition to the automatic control system, a monitoring camera is added to provide redundant detection reserves, making the entire system more stable.

[0039] It should be noted that the accompanying drawings merely illustrate the technical concept of the present invention and should not be used to limit the scope of protection of the present invention. For those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and all such improvements and modifications fall within the scope of protection of the claims of the present invention.
