At present, there are many kinds of contact float switches on the market, but the principle is roughly similar. When the liquid level rises, the float rises with it. When the float is close to the top, the magnet inside the float attracts the magnet with the opposite magnetic pole on the top, making the float The internal circuit is turned on, so as to play the role of switch. This type of float switch does not consider the surge of liquid. When the float is in the liquid with large fluctuations in the liquid level, a slightly large fluctuation of the liquid level can trigger the float switch. , so that the circuit of the external device enters the working state. When the liquid falls back, the circuit of the external device is disconnected instantly, resulting in waste of resources, frequent power-off, and shortening the life of the device.
Therefore, the existing float switches generally have the defects of low precision and no anti-surge function

The invention relates to the technical field of automatic control, in particular to an electrical connection device and a control system. An electrical connection device, comprising: a starting device, including a starting unit, a trigger unit and a timing unit; a liquid level detection device, used for detecting the height of the liquid level, and controlling the starting device through the liquid level detection device. The electrical connection device and the control system of the present invention have at least the following advantages: by setting the timing unit, the starting unit is prevented from being connected to the circuit due to surge, the problem of frequent power on and off is solved, and the service life of the electrical connection device is prolonged.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to an electrical connection device and a control system. Background technique [0002] Now, the equipment in all aspects of life and work are related to the liquid level of the liquid, such as water conservancy, agriculture, flood control and drought relief, and industry. For example, many places enter the rainy season every summer, and a large amount of rainfall will cause the water level of rivers and lakes to rise, bringing disasters to human beings. When the water level rises to a certain point, it is necessary to implement flood discharge and issue an alarm; Water will greatly reduce the output of agriculture. When the water level drops to a certain height, in order to ensure sufficient water in the farmland, it is necessary to release water from the reservoir; in some equipment, due to lack of water and oil, the equipment will be damaged. Therefore, when the liquid ...
