[0015] La figura 2 representa una interfaz 14 de la unidad 12 de control electrónica que incluye un conjunto predeterminado de terminales de potencia, no mostrados, a los cuales se pueden conectar, por ejemplo, una fuente de energía eléctrica tal como una batería de un automóvil, para que, suministre energía eléctrica al motor a través del convertidor de energía eléctrica; un ventilador, etc.[0015] Figure 2 depicts an interface 14 of the electronic control unit 12 that includes a predetermined set of power terminals, not shown, to which a source of electrical power such as a battery of for example can be connected. a car, so that, it supplies electric power to the engine through the electric power converter; a fan, etc.
[0016] Además, la interfaz 14 comprende un puerto 13 de comunicaciones que incluye un conjunto predeterminado de terminales 20 de datos adecuados para transmitir y/o recibir señales de datos hacia o desde un medio 18 de procesamiento de datos, el cual puede comunicarse con un dispositivo de comunicaciones tal como un ordenador, no mostrado, por medio de un protocolo de comunicaciones.[0016] In addition, the interface 14 comprises a communications port 13 that includes a predetermined set of data terminals 20 suitable for transmitting and / or receiving data signals to or from a data processing means 18, which can communicate with a communications device such as a computer, not shown, by means of a communications protocol.
[0017] Un terminal 20 de datos es conectable a un LED, a fin de que cuando la unidad 11 de supervisión y control detecte un mal funcionamiento del compresor por medio del medio 18 de procesamiento, a saber, micro procesador, genere una señal de alarma que es acoplada a una primera salida 15, conectable al LED a través del terminal 20. Este terminal 20 se conoce como terminal de alarma.[0017] A data terminal 20 is connectable to an LED, so that when the monitoring and control unit 11 detects a malfunction of the compressor by means of the processing means 18, namely, microprocessor, it generates a signal of alarm that is coupled to a first output 15, connectable to the LED through terminal 20. This terminal 20 is known As alarm terminal.
[0018] Por tanto, el LED se enciende cuando se genera la señal de alarma, de manera que si está ubicado en el salpicadero de un automóvil, por ejemplo, un observador ubicado en el interior del habitáculo del automóvil percibe que el compresor hermético está funcionando mal, pudiendo actuar en consecuencia a las instrucciones de haya recibido del fabricante del automóvil. Por ejemplo, desconectando el compresor para evitar la destrucción del compresor hermético.[0018] Therefore, the LED turns on when the alarm signal is generated, so that if it is located on the dashboard of a car, for example, an observer located inside the car interior perceives that the hermetic compressor is malfunctioning, being able to act accordingly to the instructions received from the car manufacturer. For example, disconnecting the compressor to prevent the destruction of the hermetic compressor.
[0019] Además, la unidad 12 de control y supervisión comprende un primer elemento 17 de conmutación conectado entre el terminal 20 de alarma y la primera salida 15 del procesador 18 por medio de la cual se suministra la serial de alarma.[0019] In addition, the control and supervision unit 12 comprises a first switching element 17 connected between the alarm terminal 20 and the first output 15 of the processor 18 by means of which the alarm serial is supplied.
[0020] La función de dicho conmutador 17 es evitar que el procesador 18 de datos reciba energía eléctrica a través de la primera salida 15, cuando una fuente de energía eléctrica está conectada a una segunda salida 16 del procesador 18 a través del terminal 20 de alarma.[0020] The function of said switch 17 is to prevent the data processor 18 from receiving electrical power through the first output 15, when an electrical power source is connected to a second output 16 of the processor 18 through the terminal 20 of alarm.
[0021] Análogamente, se puede instalar un segundo elemento 19 de conmutación entre el terminal 20 y el segundo terminal 16, no instalando el conmutador 17. Dicho segundo conmutador 19 llevaría a cabo la mismo función que el primer conmutador 17. O se podrían instalar ambos conmutadores 17, 19 para evitar que el procesador 18 reciba energía desde el terminal 20 a través del segundo terminal 16. Obviamente, la unidad de control y supervisión conduciría la conmutación entre abierto y cerrado de uno o de ambos conmutadores 17, 19 por medio de un algoritmo de conmutación que tiene almacenado.[0021] Similarly, a second switching element 19 can be installed between terminal 20 and second terminal 16, not installing switch 17. Said second switch 19 would perform the same function as first switch 17. Or they could be installed. both switches 17, 19 to prevent the processor 18 from receiving power from terminal 20 through the second terminal 16. Obviously, the control and supervision unit would conduct the switching between open and closed of one or both switches 17, 19 by means of a switching algorithm that it has stored.
[0022] Se ha de observar que dicha fuente no es capaz de suministrar energía al motor eléctrico del compresor. El motor eléctrico puede ser un motor de corriente alterna.[0022] It should be noted that said source is not capable of supplying power to the electric motor of the compressor. The electric motor can be an alternating current motor.
[0023] Por otro lado, tanto el primer conmutador 17 como el segundo conmutador 19 pueden ser, por ejemplo, un diodo, un transistor, un transistor de efecto campo, MOSFET, o similar.[0023] On the other hand, both the first switch 17 and the second switch 19 can be, for example, a diode, a transistor, a field effect transistor, MOSFET, or the like.
[0024] Resumiendo, un predeterminado terminal de datos del puerto 13 de comunicaciones tiene un doble uso, un primer uso como terminal 20 de alarma a través de cual se aplica una señal de alarma a un LED, y segundo uso como terminal 20 de energía a través del cual se suministra energía eléctrica al procesador 18 de datos. [0024] In short, a default data terminal on port 13 of Communications has a dual use, a first use as an alarm terminal 20 through which an alarm signal is applied to an LED, and a second use as an energy terminal 20 through which electrical power is supplied to the data processor 18.
