Description

Pump house intelligent control node and thing networking water pump intelligent control system who constitutes thereof Technical Field The invention relates to the technical field of intelligent control of pump rooms, in particular to an intelligent control node of a pump room and an intelligent control system of an internet of things water pump formed by the intelligent control node. Background The pump house is a building for installing a water pump, a motor, a water pump control cabinet and other auxiliary equipment, is a main body of a water pump station engineering, and has the main function of providing good working conditions for a water pump unit, the auxiliary equipment and operation management staff. Because pump rooms, particularly water supply pump rooms, are located close to water source sites, most of which are located in suburban fields, most of the pump rooms are scattered in suburban field rivers, reservoirs and other areas. At present, most small-size pump stations still adopt traditional manual operation mode, rely on the staff to draw water according to instrument parameter and operational experience control water pump, and a part of pump stations have used water level float to cooperate simple and easy remote control unit can realize simple semi-automatic operation, but this kind of mode can only be made to the height of water level in the pond, easily receive external interference, and is unreliable. The partial control system uses a PLC or a singlechip as a control core, can simply judge equipment and water level conditions to realize partial automatic control function, and can realize automatic control in the mode, but still needs manual assistance. Simple mechanical single water level control can not automatically predict and adjust operation parameters according to water consumption conditions, does not have a multiple detection fault tolerance mechanism, and can not timely make emergency treatment when a sensor fails. The system has no functions of monitoring the running states of the water pump, the motor and the frequency converter and warning faults, can not be found and processed in time in the early stage of the equipment entering an abnormal working state, and is easy to cause equipment damage and even fire disaster. Because of the lack of corresponding intelligent networking equipment between each pump station, the independent operation mode is adopted between each pump station, and each water source is difficult to comprehensively schedule in the independent operation mode, the pump station with sufficient water source is also stopped after partial pump station low water level stopping possibly, the requirement of maximally acquiring the water source cannot be met, and a worker is often required to mechanically test each independent pump room to pump water and stop the pump, so that huge workload is generated. This kind of mode is difficult to make accurate judgement to the water demand, causes the high-order pond circulation slow when the water consumption is little, and quality of water is easily polluted. When the water consumption is large, the high-level water tank does not store water enough, so that the water pressure is reduced and even water is stopped. Disclosure of Invention In order to solve the technical problems, the intelligent control node of the pump house is provided, the intelligent control node can monitor the water quantity of a water pool at the position, monitor the running state of a motor in the pump house, early warn the motor when the motor movement temperature is too high so as to facilitate timely maintenance of workers, an intelligent control system of the water pump of the Internet of things, which is formed by the intelligent control node of the pump house of each pump station and a data service center, can realize reliable communication of nodes such as a water pump and a water tower by utilizing the Internet of things technology, can comprehensively analyze the current water consumption condition by utilizing the big data technology, predicts the water consumption for a period of time in the future, reduces the pumping trigger water level when the water consumption is small, prolongs the equipment downtime, reduces the starting times, achieves the aim of reducing equipment abrasion, can improve the water storage capacity when the pumping trigger water level is large, ensures stable water supply, and simultaneously can synthesize the water source condition of each pump station, scientifically schedule, and effectively improve the water source utilization rate and the water supply capacity. In order to achieve the technical effects, the invention is realized by the following technical scheme: pump house intelligent control node includes The shell is used for packaging the control circuit board; The display screen is used for displaying the input water level information of the water tank and the operation temperature information of the motor;
