Problems solved by technology
The main defects are: 1: Only the total power of the dormitory is controlled, and multiple low-power devices are used at the same time, which may also cause the power to exceed the threshold and be cut off; 2: When the power exceeds the threshold, there is no alarm prompt, Or when there is an alarm prompt, but because the entry meters are all installed centrally, the alarm basically has no practical effect

Embodiment Construction
[0027] The technical solutions of the present invention will be clearly and completely described below through specific embodiments in conjunction with the accompanying drawings.
[0028] Such as figure 1 As shown, a dormitory management method for high-power equipment specifically includes the following steps:
[0029] Set the sampling time interval, prohibited power threshold, limited power threshold, and time regulation threshold;
[0030] Sampling, sampling the current signal and voltage signal of the outgoing line every other sampling time interval;
[0031] Calculate and obtain the corresponding current power according to the sampled current signal and voltage signal;
[0032] Judgment of prohibited power, compare the current power with the prohibited power threshold, if the current power is greater than the prohibited power threshold, send a switch signal and cut off the outgoing power supply; if the current power is less than the prohibited power threshold, perform l...

The invention discloses a dormitory high-power equipment management method and a controller. The controller comprises an AC sampling module, which is used for collecting the current signal and voltage signal of an outgoing line every 250 ms, and transmitting the sampled signals to an MCU control module; the MCU control module, which is used for generating current power according to the sampled signals, and comparing the current power with a prohibited power threshold value and a limit power threshold value, and if the current power is larger than the prohibited power threshold value, sending a switch-out signal to a relay control module to cut off an outgoing line power supply; and if the current power is smaller than the prohibited power threshold value and is larger than the limit power threshold value, starting to time, and when reaching the time predetermined value, sending the switch-out signal to the relay control module to cut off the outgoing line power supply. The difficulty of power control of sockets in a dormitory is solved, thereby preventing use of prohibited electrical equipment, limiting use time of a part of electrical equipment, and ensuring electric utilization safety of the dormitory; and the electrical equipment is controlled in a manner of combining power control and time control.
Description
technical field [0001] The invention relates to the field of electricity safety management equipment, in particular to a management method and controller for dormitory high-power equipment. Background technique [0002] At present, the control of high-power electrical equipment in the dormitory is generally realized by using the power control function of the household meter and setting the corresponding power threshold through the remote system. The main defects are: 1: Only the total power of the dormitory is controlled, and multiple low-power devices are used at the same time, which may also cause the power to exceed the threshold and be cut off; 2: When the power exceeds the threshold, there is no alarm prompt, Or when there is an alarm prompt, but because the entry meters are all installed centrally, the alarm has basically no practical effect. Contents of the invention [0003] The purpose of the present invention is to provide a management method and controller for ...
