It relates to an automatic premises power control device using the.

In general, the automatic power control device according to the prior art monitors the amount of power used, the alarm signal is generated at the output port for each class, but when the alarm occurs, there is no choice but to directly connect the wire to the switch of the equipment to turn off the power.

In addition, it is even more impossible to install the switch of the equipment installed in the entire building by wire to the power control room.

Therefore, when you want to control the power switch of a specific refrigerator that consumes a lot of power, it is controlled by wires. However, the refrigerator is a facility that directly affects production, causing damage to the production. Even if it is normalized, there is no inconvenience to turn it on manually because there is no way to turn it on automatically.

Accordingly, an object of the present invention is to solve the above-mentioned problems, and to wirelessly design the entire system, and to automatically control the premises power wirelessly to save electricity bills, to prevent the rise above the contracted power, and in the summer Increasing the use of electricity, even when peak power is used, important facilities are not shut down.Wireless control systems can be connected to a TCP / IP network, allowing multiple devices to be controlled simultaneously.

In this case, the control signal uses encrypted data as a control signal to prevent a malfunction of the wireless remote controller 300.

That is, when an alarm signal for each grade generated by the automatic power control device 500 is received, the controller generates an control signal of a wireless remote controller to be wirelessly turned on and off by analyzing the alarm signal.

The control signal generated as described above is converted into a wireless protocol by the POCSAG protocol generator 207 or the Zigbee protocol generator 208 and emitted as a radio wave through the FM transmitter 209 and the antenna 210.

In addition, in order to prevent the peak value from being instantaneously turned on at the time of restoration and being turned on at the time of restoration, the function is specialized as follows.

Register up to 20 wireless remote controllers 300 to be controlled for each alarm signal, and when the alarm signal is generated, the contacts of the wireless remote controller 300 are simultaneously open (powered off) to drastically reduce the amount of power used, and the alarm recovery signal. In case of occurrence of a delay time by separately contacting the wireless remote controller 300 to prevent the close (power ON) at the same time to minimize the load generated when the power is ON.

Of course, the delay time of each of the wireless remote controller 300 was made to be edited by the program in the operating PC (400).

In addition, the wireless remote controller 300 has two switches in the wireless remote controller 300 in preparation for two industrial air conditioners in one device, and the delay time when the two switches are also closed (powered on). The setting was made possible.

When the wireless remote controller 300 receives a control signal, an acknowledgment response signal is automatically generated. The acknowledgment signal is transmitted to the wireless control system 200 as a wireless signal, and each wireless control system 200 transmits a wireless acknowledgment signal. You can monitor the operation status of the remote controller.

In addition, the operating PC 400 invented to automatically save all the signal generation status, such as alarms as a monitor and log file, and has the function to send all the operation status as text to the pager or mobile phone of the person in charge.

Automatically turn on / off the power of equipment such as air conditioner.

In addition, the main controller 304 sends the received signal back to the wireless transmitter 302 as a recognition signal to emit radio waves so that the wireless controller system 200 can check whether the wireless controller 300 receives the received signal. do.

The contact part 308 uses a three-port contact type of Common, Normal Open, and Normal Close type in order to be utilized in various products, and also has a high-capacity, high-capacity AC / to control all power equipment in the premises. DC dual relay was used.

That is, the contact port acts as a switch when the power OFF signal is received to the corresponding wireless remote controller 300 and automatically turns off the power, and when the power ON signal is received, the power is automatically turned on.

In addition, in order to manually turn on the switch automatically turned off by the radio signal, a switch unit 309 for manually operating each contact point is attached to the front of the invention to add convenience.

In addition, the two switches in the device have their respective IDs.When the power is turned off, the two switches are turned off at the same time to turn off the power.When the power is turned on, the two switches are turned off to reduce the load generated when the power is turned on.
