Esto se realiza mediante la medición de la corriente que circula por la bobina, la corriente es función del campo electromagnético. Esta corriente se mide en una resistencia de un ohm, la cual se encuentra en serie con la bobina, y lo que se toma es el voltaje, que por ley de ohm será equivalente a la corriente. Este voltaje debe ser medido por el microcontrolador, por lo cual es necesario primero pasarlo por una etapa de conversión de voltaje variable a un voltaje RMS, voltaje en CD equivalente al variable. Para esto se utiliza un circuito especial señalado como AD536. La salida de este voltaje es introducida a uno de los puertos del microcontrolador, el cual tiene la característica de poder realizar la conversión de analógico a digital, por lo que en esta etapa es posible procesar la señal proveniente del campo electromagnético. El microcontrolador evalúa si esta señal se encuentra dentro de un rango del ±10% del campo calibrado de 9 Gauss. Si la evaluación es positiva, entonces el micro activara los botones controladores manuales de ascendente/descendente del equipo y se podrá realizar un tratamiento estableciendo el tiempo necesario; por otro lado, se enciende un led de color azul y se mantendrá encendido para indicar que el equipo está en condiciones de funcionamiento, si la evaluación es negativa un led naranja permanecerá parpadeando en señal de que el equipo requiere mantenimiento. The device has a field current sensor consisting of a shunt resistor, connected in series with the coil, which allows monitoring the current that is related to the generation of the electromagnetic field. The sensor signal is sent directly to a VAC to VRMS converter, which allows you to convert the signal from analog to digital. The microcontroller has been previously calibrated to produce the desired electromagnetic field strength, preferably with a 9 Gauss intensity. When the equipment is turned on, a self-test routine is initiated, in which the magnetic field is monitored to have the appropriate intensity previously preset with the calibration. This is done by measuring the current flowing through the coil, the current is a function of the electromagnetic field. This current is measured at a resistance of one ohm, which is in series with the coil, and what is taken is the voltage, which by ohm's law It will be equivalent to the current. This voltage must be measured by the microcontroller, so it is first necessary to pass it through a stage of conversion of variable voltage to an RMS voltage, voltage on CD equivalent to the variable. For this, a special circuit designated as AD536 is used. The output of this voltage is introduced to one of the ports of the microcontroller, which has the characteristic of being able to convert from analog to digital, so at this stage it is possible to process the signal from the electromagnetic field. The microcontroller evaluates whether this signal is within a range of ± 10% of the 9 Gauss calibrated field. If the evaluation is positive, then the micro will activate the manual up / down control buttons of the equipment and a treatment can be made establishing the necessary time; on the other hand, a blue LED is lit and it will remain lit to indicate that the equipment is in working condition, if the evaluation is negative, an orange LED will continue to flash in signal that the equipment requires maintenance.
Cuando se realiza un tratamiento, el usuario debe fijar el tiempo necesario, el tiempo se regula por medio de dos botones, uno de ellos establece el tiempo de manera ascendente y el otro de manera descendente, esta información puede ser apreciada en una pantalla de despliegue de tres dígitos y de siete segmentos. Estos botones están conectados directamente a un microcontrolador, el cual es encargado de incrementar o disminuir la escala de conteo de un contador con un valor preestablecido, así como también realiza la lógica necesaria para mostrar dicha información en el despliegue, el cual se controla a través de sólo tres líneas de control, utilizando el protocolo de comunicación SPI. Esto a diferencia de los despliegues de siete segmentos normales que requerirían una línea de control por cada segmento, es decir, si hubiera la necesidad de manejar tres dígitos, requerimos veintiuna líneas de control, o de lo contrario debemos multiplexar las líneas de datos y utilizar transistores para su control, necesitando diez líneas de control. Una vez que se ha fijado el tiempo de tratamiento, el usuario debe presionar el botón de inicio, lo cual indicara al microcontrolador que la cantidad fijada en el despliegue debe de comenzar el conteo inverso por medio de un temporizador el cual está calibrado para desplegar la información en cada segundo. El microcontrolador dará la instrucción a un circuito que consta de un transistor y que funciona como interruptor para activar un relevador, el cual permitirá la conexión de las bobinas al voltaje rectificado a 120Hz. También se activan tres ventiladores como sistema de refrigeración de las bobina, y de esa manera proporcionar confort para el usuario al evitar el calor excesivo generado por la bobina Helmholtz. When a treatment is carried out, the user must set the necessary time, the time is regulated by means of two buttons, one of them sets the time upwards and the other downwards, this information can be appreciated on a display screen three digits and seven segments. These buttons are directly connected to a microcontroller, which is responsible for increasing or decreasing the counting scale of a counter with a preset value, as well as performing the logic necessary to display such information in the display, which is controlled through of only three control lines, using the SPI communication protocol. This, unlike the deployments of seven normal segments that would require a control line for each segment, that is, if there is a need to handle three digits, we require twenty-one control lines, or else we must multiplex the data lines and use transistors for its control, needing ten control lines. Once the treatment time has been set, the user must press the start button, which will indicate to the microcontroller that the amount set in the deployment should start the reverse count by means of a timer which is calibrated to display the information in every second. The microcontroller will instruct a circuit consisting of a transistor and that functions as a switch to activate a relay, which will allow the connection of the coils to the rectified voltage at 120Hz. Three fans are also activated as the coil cooling system, and thus provide comfort for the user by avoiding excessive heat generated by the Helmholtz coil.
En la carátula se encuentra también un semi-círculo de leds indicadores que encienden de manera secuencial en la dirección de las manecillas del reloj y regresaran a punto de inicio en el sentido contrario, el encendido o la iluminación de los leds se presenta de manera cíclica mientras el equipo este en operación.  The dial also contains a semi-circle of indicator LEDs that turn sequentially in the clockwise direction and will return to the starting point in the opposite direction, the ignition or illumination of the LEDs appears cyclically while the equipment is in operation.
Mientras se despliegan las señales luminosas en la carátula del aparato de la presente invención, el microcontrolador se encuentra disminuyendo la escala de conteo de los contadores, y se encarga de enviar la información de los minutos restantes al despliegue, al faltar un minuto la cuenta que se apreciará en el despliegue será el conteo regresivo en segundos. Al finalizar, se desactivaran los interruptores de la bobina, de los ventiladores y del despliegue de leds; también se envía una señal a un buzzer que provoca una señal audible por un tiempo de un segundo de manera intermitente para indicar que el proceso ha terminado.  While the light signals are displayed on the cover of the apparatus of the present invention, the microcontroller is decreasing the counting scale of the counters, and is responsible for sending the information of the remaining minutes to the deployment, when the account is missing for a minute It will be appreciated in the display will be the countdown in seconds. When finished, the coil, fan and LED display switches will be deactivated; A signal is also sent to a buzzer that causes an audible signal for a period of one second intermittently to indicate that the process is over.
Una de las características especiales del equipo, consiste en que al microcontrolador se le ha prefijado un tiempo de uso máximo. Este lleva un contador, cuyo resultado se almacena en la memoria EEPROM. Este sumador se incrementa cada vez que se solicita realizar la prueba de calibración. Es decir, si el micro detecta que debe realizar su prueba de calibración, primero verifica el valor que tiene almacenado en memoria y lo compara con el resultado del contador (el cual también está en memoria). Si el contador es menor, entonces procede a realizar el algoritmo de calibración antes mencionado; de lo contrario, el microcontrolador encenderá el led anaranjado indicando que se requiere mantenimiento. Por lo cual, el botón de inicio no se activa y se informa en pantalla que se requiere servicio de mantenimiento y que debe llamar al técnico de mantenimiento y que reinicie el contador del microcontrolador, esto mediante la programación del micro, o bien mediante una conexión especial de pines, y con la aplicación de pulsos de voltaje, con los cuales será posible borrar el resultado del contador en la memoria EEPROM. Realizando esto, es posible volver a utilizar el equipo. La calibración periódica es necesaria para asegurar la homogeneidad de líneas de campo dentro de la bobina, ya que es necesaria una intensidad de campo constante. One of the special characteristics of the equipment is that the microcontroller has been set a maximum usage time. This carries a counter, whose result is stored in EEPROM memory. This adder is incremented each time the calibration test is requested. That is, if the micro detects that it must perform its calibration test, it first verifies the value it has stored in memory and compares it with the result of the counter (which also is in memory) If the counter is lower, then proceed to perform the calibration algorithm mentioned above; otherwise, the microcontroller will turn on the orange LED indicating that maintenance is required. Therefore, the start button is not activated and it is informed on the screen that maintenance service is required and that you should call the maintenance technician and reset the microcontroller counter, this by programming the micro, or by connecting special pin, and with the application of voltage pulses, with which it will be possible to erase the result of the counter in EEPROM memory. By doing this, it is possible to reuse the equipment. Periodic calibration is necessary to ensure the homogeneity of field lines within the coil, since a constant field strength is necessary.
