The present invention relates to a power measurement monitor using a Bluetooth module, and more particularly, to a power measurement monitor using a Bluetooth module that can determine the contour of power consumption in a home by installing a power measurement monitor in a home power distribution panel. It is about.

1 is a block diagram showing an example of an electric circuit of a measuring apparatus according to the related art.

Referring to the drawings, in Fig. 1, reference numeral 1 denotes a rotation type integrated power meter having a rotating disc 2 and a driving element 3 for rotating the rotating disc 2, and having a photo sensor therein. (4) is installed.

The rotating disc 2 is configured to drive the detection unit at a predetermined angle on a circle centered on the axis 5, and the shaft 5 at a speed proportional to the power consumption at the load by the driving element 3. It is rotated around.

The detected part is a light and dark part consisting of a part which reflects light and a part which does not reflect, and is provided radially.

Such a detection part further has a dark part 8... In the outer peripheral part of the light reflective rotating disc 2 as shown in FIG. May be applied or printed, or the film 9 having the light and dark portions alternately baked in a circle as shown in FIG. 2 (b) may be attached to the rotating disc 2.

The driving element 3 uses a current coil, a voltage coil, and a coil of coils wound around a current coil, a voltage coil, and a coil connected between a load 10 such as a motor and a power supply source 11 in which power consumption is measured. It is a known element and rotates the rotating disk 2 by the magnetic flux which generate | occur | produces in a coil.

The photosensor 4 is composed of a pair of light emitting elements and a light receiving element such as a light emitting diode and a photo transistor, and the light rays emitted from the light emitting elements are irradiated to the detection unit of the rotating disc 2 and reflected from the detection unit (transmission Light beams) may be incident on the light receiving element.

Since the light sensor incident on the light-receiving element is blocked every time the detection unit passes by the rotation of the rotating disc 2, the photosensor 4 outputs a pulse signal to the counter 12 each time the detection unit passes. do.

The counter 12 counts the pulse signal input from the photosensor 4 as a binary code or a binary coded code, and its output terminal is an indicator 13 and a comparator 14a which visually display the power consumption. ), (14b),... And an output terminal 15 to an external device such as a printer for data recording.

The contents of the counter 12 correspond to the amount of power consumption because a pulse signal is generated every time the detection unit passes the photosensor 4 in accordance with the rotation of the rotating disc 2.

Therefore, if the photo sensor 4 forms the detection unit so that the load sensor 10 can generate a pulse signal whenever the load 10 consumes 1 WH, the amount of power consumption can be measured in units of WH.

The display 13 visually displays the amount of power consumption using the contents of the counter 12, and displays the comparators 14a, 14b,... Outputs an electrical signal meaning that when the contents of the counter 12 match the contents set in the setting switches 16a, 16b, ....

The output signals of each of the comparators 14a, 14b, ... are used as signals for controlling peripheral devices such as additive injectors. Setting switches 16a, 16b,... For example, a digital switch can be used.

In the above-described measuring device, the rotating disc 2 is rotated to the load 10 in a number of times proportional to the amount of power consumed, and the photosensor 4 generates the number of pulse signals proportional to the rotational speed of the rotating disc 2. Therefore, the contents of the counter 12 increase in proportion to the amount of power consumed by the load 10, and the amount of power consumed is displayed on the display 13.

Therefore, the degree of processing can be known by visually seeing the value displayed on the indicator 13.

In addition, the contents of the counter 12 are set by the switch 16a, 16b,... If the contents match the values set in, the comparators 14a, 14b,... Since an electric signal is generated, for example, the most suitable power consumption until the addition of the compounding agent in the mixing of rubber or the like is set in the setting switch 16a, and the most suitable power consumption until the oil input is set. The amount of power consumption most suitable until the addition of each additive, such as setting in the switch 16b, is set in each of the setting switches 16a, 16b,... The comparators 14a, 14b,. A predetermined peripheral device such as an oil injector is driven by the output signal of each so that it can always be processed under appropriate conditions.

Table 1 and Table 2 show the measurement results of the amount of power consumption when rubber is mixed with a half-barrier using the above apparatus.

The timing of oil input, which shows a great influence on the dispersion of the compounding agent, or the timing of the dump-out, which indicates the degree of mixing, is particularly important when continuously mixing the same kind of rubber. As a conventional measuring apparatus, the power consumption is 100 WH. Although it is only a measure of a unit, according to the above-mentioned apparatus, the power consumption of 1 WH or less can be measured, and the degree of processing, such as oil injection timing, can be known correctly.

In addition, using the above apparatus, the power consumption when the rubber was processed under the conditions of a sheet thickness of 4 mm and a roll temperature of 60 ° C. was measured by a roll mixer. The power consumption of the processed rubber was 100.0 WH per 1 kg of rubber. As a result, it was found to be almost constant, and as a result, it was possible to easily control the homogenization of the rubber.

In addition, the electric circuit of the measuring device according to the prior art can be used not only for high precision control by mounting on a laboratory rubber processing machine, but also for actual processing equipment in a factory, and in particular, a rubber continuous processing machine installed in a factory. It is most suitable to use.

In addition to the rubber processing machine, materials other than rubber such as plastic can be applied to the apparatus for measuring the power consumption of the processing machine.

As described above, the electric circuit of the measuring device according to the prior art forms a radial contrast portion at a predetermined angle on the rotating disc of the rotary integrated power meter, detects the intensity portion with a photosensor, counts the output signal with a counter, Since the electric signal is generated when the content of the counter reaches a predetermined value, power consumption of 1 WH or less can be accurately and easily measured by a simple device, and thus the degree of processing can be accurately known, Machining can be efficiently performed with high precision.

However, the electric circuit of the measuring apparatus according to the related art, which is configured as described above, has a disadvantage in that it is not possible to properly grasp the contour of power consumption in the home for each installed channel.

The present invention has been made to solve the above problems, by providing a power measurement monitor in the home power distribution panel to provide a power measurement monitor using a Bluetooth module that can grasp the outline of the consumption of power energy in the home for each installed channel.

The current measuring unit 40 generates a magnetic field when a current flows through the power line as a non-contact core. The magnetic field generates an electric field in the secondary winding of the core so that the current flows in the secondary winding according to the amount of current in the power line. will be.

In this case, when the current flowing is detected, the amount of current of the primary power line may be measured.
