A system can be applied to different monitoring objects, so that the universality, transportability and economy of the system are high.

Description

technical field [0001] The invention relates to an online energy consumption test and analysis system of a water pump based on a wireless sensor network, in particular to an online energy consumption test and analysis method of a water pump based on a wireless sensor network. Background technique [0002] Pump is an important equipment for energy conversion and fluid transportation. It has a wide variety and large output. As a general-purpose machine, it has been widely used in various sectors of the country's economy. However, the annual power consumption of pump products in my country accounts for about 1 / 3 of the country's power consumption. The power consumption is huge, and the situation of energy saving is very severe. Pump products consume a lot of power. It is of great significance to monitor their energy consumption, obtain the operating conditions and energy consumption indicators of the pump, and provide strategies for energy-saving and safe operation in the later...

Problems solved by technology

[0004] In the pump energy consumption monitoring system, the pump speed and motor efficiency are difficult to measure online in real time

Most of the current speed measurement solutions are not very universal, and sufficient installation space needs to be reserved on the pump or motor. When the test object cannot be stopped, there is no mechanical structure with sensors installed, or in the case of strong external electromagnetic interference, These test methods cannot be applied

The motor efficiency measurement needs to provide the motor rated loss and no-load loss data, but the drive motors that are currently shipped with the pump generally do not provide these data

In the actual process of the project, you can refer to the relevant parameters of the standard motor, but due to the difference in processing and manufacturing, there are actually differences between the parameters of each motor and the standard motor

These two parameters are directly related to the calculation of the motor efficiency, and the motor performance test needs to be carried out separately when obtaining it. It is obviously unable to meet the test requirements when the test in the non-stop state is required or the motor performance test is not available.
