CAMPO TÉCNICO DE LA INVENCIÓN TECHNICAL FIELD OF THE INVENTION
La presente invención pertenece al campo de la electrónica pues el invento se refiere a un sistema de control automático y de seguridad de esterilizador de canales de carne utilizando componentes electrónicos y de comunicaciones. The present invention belongs to the field of electronics as the invention relates to an automatic and safety control system for meat channel sterilizer using electronic and communications components.
ANTECEDENTES BACKGROUND
La presente invención se refiere a un método operativo para el control de un dispositivo de automatización, en el que al menos la seguridad y / o la fiabilidad del dispositivo de control ya ha sido verificada. The present invention relates to an operating method for the control of an automation device, in which at least the safety and / or reliability of the control device has already been verified.
Dispositivos y sistemas de automatización son generalmente conocidos. Se utilizan para el control de procesos e instalaciones técnicas en muchas áreas. Ejemplos de dispositivos de automatización y sistemas de automatización son controladores CNC (control numérico computarizado), controladores MC (control de movimiento) y controladores SPS (control de programa almacenado), con elementos periféricos. Automation devices and systems are generally known. They are used for process control and technical installations in many areas. Examples of automation devices and automation systems are CNC controllers (computer numerical control), MC controllers (motion control) and SPS controllers (stored program control), with peripheral elements.
En muchos casos, los dispositivos y sistemas de automatización llevan a cabo funciones de seguridad. En tales casos, los dispositivos y sistemas correspondientes deben ser seguros. In many cases, automation devices and systems perform security functions. In such cases, the corresponding devices and systems must be safe.
La verificación de una seguridad funcional de los dispositivos y sistemas requiere el cálculo de la tasa de riesgo (por ejemplo, según la norma IEC 61508-6 Apéndice B). La base para los cálculos son modelados con respecto a la seguridad funcional y el cálculo de estos modelados a través de métodos iterativos, aproximaciones lineales o en el caso de las más simples modelados por soluciones cerradas.
En los dispositivos o sistemas que pueden funcionar en varias configuraciones complejas, es posible especificar no sólo un único valor numérico como tasa de riesgo. En cambio, la tasa de riesgo debe determinarse por separado para cada configuración. En este contexto, el gasto y también la posible amplitud de los (correctas) tasas de riesgo aumentan en gran medida con la multiplicidad de componentes y sus posibles combinaciones. The verification of a functional safety of the devices and systems requires the calculation of the risk rate (for example, according to IEC 61508-6 Appendix B). The basis for the calculations are modeled with respect to functional safety and the calculation of these modeled through iterative methods, linear approximations or in the case of the simplest modeled by closed solutions. In devices or systems that can operate in several complex configurations, it is possible to specify not only a single numerical value as the risk rate. Instead, the risk rate must be determined separately for each configuration. In this context, the expense and also the possible breadth of the (correct) risk rates increase greatly with the multiplicity of components and their possible combinations.
Los valores determinados son parte de un sistema de seguridad. Por lo tanto, son también un componente de los documentos de certificación que se presentan en un instituto de certificación correspondiente licencia para la certificación de estos dispositivos o sistemas. The determined values are part of a security system. Therefore, they are also a component of the certification documents that are presented at a corresponding certification institute for the certification of these devices or systems.
En la técnica anterior, la tasa de riesgo se calcula por un experto. Como regla general, se trata de la misma persona que también crea otras partes de los documentos requeridos para la certificación. La tasa de riesgo determinado por el experto está marcada por la Oficina de Certificación. En este proceso, se comprueban los modelos básicos y sus enfoques (ecuaciones o algoritmos), entre otras cosas. In the prior art, the risk rate is calculated by an expert. As a general rule, it is the same person who also creates other parts of the documents required for certification. The risk rate determined by the expert is marked by the Certification Office. In this process, the basic models and their approaches (equations or algorithms) are checked, among other things.
En la técnica anterior, los sistemas complejos requieren una simplificación con el fin de mantener la complejidad matemática dentro de un marco razonable. La simplificación consiste en que un número de configuraciones se combinan y el más peligroso de estos se considera. Para la reducción del número de posibles configuraciones, los valores de riesgo correspondientes se especifican en forma de tabla de modo que el usuario puede seleccionar una configuración que cumple sus requisitos de seguridad. In the prior art, complex systems require simplification in order to maintain mathematical complexity within a reasonable framework. The simplification is that a number of configurations are combined and the most dangerous of these is considered. For the reduction of the number of possible configurations, the corresponding risk values are specified in a table so that the user can select a configuration that meets their safety requirements.
La tasa de riesgo debe determinarse es un parámetro relacionado con la seguridad. Por esta razón, los algoritmos, valores numéricos etc. formando la base de la determinación de la tasa de riesgo también están a su vez relacionada con la seguridad. El uso de herramientas generales de cálculo (programas de matemáticas, cálculo de mesa, etc.), es fundamental ya que tales herramientas de software y las plataformas de hardware asociados debe ser sometido a los requisitos relacionados con la seguridad que se puede o no se cumplieron o sólo se pueden cumplir con modificaciones muy incómodos para el cliente.
Por tanto, sería deseable y ventajoso proporcionar posibilidades de ser capaz de proporcionar de una manera sencilla, con una fiabilidad cuantitativa, información acerca de la fiabilidad de un sistema de automatización que deben evaluarse. The risk rate should be determined is a safety related parameter. For this reason, algorithms, numerical values etc. forming the basis of the determination of the risk rate are also in turn related to safety. The use of general calculation tools (math programs, table calculations, etc.) is essential since such software tools and associated hardware platforms must be subject to security related requirements that may or may not be met or can only be met with very uncomfortable modifications for the client. Therefore, it would be desirable and advantageous to provide possibilities of being able to provide in a simple manner, with quantitative reliability, information about the reliability of an automation system to be evaluated.

DESCRIPCIÓN DETALLADA DE LA INVENCIÓN DETAILED DESCRIPTION OF THE INVENTION
En un inicio el dispositivo de desinfección se encuentra detenido con las puertas 1 y 2 de entrada y salida abiertas, Los interruptores de proximidad iproxl e iprox2 que corresponden a las puerta 1 y puerta 2 respectivamente señalan que éstas están abiertas y el proceso de desinfección se encuentra bloqueado por el protocolo de seguridad que aplica cada vez que alguno de los interruptores iproxl o iprox2 señalan abierto. Todos estos comandos son ejecutados desde un sistema de procesamiento central que esta dotado de un microcontrolador programado para estas funciones. En este punto un protocolo alterno verifica la posición de la electroválvula 1 que controla la posición de las puertas 1 y 2 simultáneamente, si la electroválvula 1 esta en posición de cerrado entonces manda una señal de alarma a una pantalla táctil de control para que las puertas y el sistema neumático de cerrado sea verificado; si la electroválvula esta en posición abierto es decir que coincide con la señal enviada por los interruptores iprox 1 e iprox 2 entonces el proceso de desinfección empieza. Las canales de res llegan al inicio del proceso de desinfección por medio de un riel por el cual ruedan unos carros unidos a unos ganchos que sujetan las canales de carne. Entonces un sujetador electromagnético atrapa el gancho donde cuelga la canal de carne o producto y un pasador electromagnético se desactiva para dejar rodar dicho carro mientras que un sensor infrarrojo monitorea que solo un carro pase a la vez; una vez que detecta el paso de un carro activa de nuevo el pasador para bloquear el paso de mas canales; a continuación el sujetador transporta el producto hacia el interior del dispositivo de desinfección movido por un motor 1 de pasos controlado por el microcontrolador. Una vez que la canal de carne se encuentra en dentro del dispositivo de desinfección dos sensores de proximidad colocados dentro miden la posición de la carne y mandan señales de ajuste al microcontrolador el cual envía señales al motor 1 para reajustes. Una vez que el producto se encuentra en posición el microcontrolador manda cerrar la electroválvula 1 que a su vez cierra las puertas administrando un flujo de aire comprimido que envía hacia un par de actuadores neumáticos colocados uno en cada puerta, entonces las puerta 1 y puerta 2 se cierran; se verifica la señal del los sensores iprox 1 e iprox 2 y si alguno de ellos marca posición abierta el proceso se detiene y se manda una señal de alarma a la pantalla táctil para su revisión, acto contrario el proceso continua. Cuatro lámparas UVC colocadas en cada esquina del dispositivo de desinfección se encienden por un lapso de 90.9 segundos para conseguir la neutralización del 99% de las bacterias, después de
que las lámparas UVC se apagan cuatro sensores de final de carrera distribuidos en pares (principio-fin) determinan la longitud del producto desde dos ángulos opuestos para que con esta información un par de tuberías en escuadra (una por cada par de sensores de final de carrerea) que tienen instalados 3 aspersores cada una puedan hacer un barrido vertical desde el inicio del producto hasta el final del mismo mientras una bomba tipo hidroneumática genera un flujo de presión de solución de quitosano a través de una electroválvula 2 que se abre para permitir el paso de la solución de quitosano hacia los aspersores que producen un patrón uniforme de rociado sobre la superficie del producto El movimiento vertical de las tuberías de escuadra es producido por el motor 2 y motor 3 de pasos respectivamente; generando así una biopelícula antibacteriana que eliminara las bacterias que la exposición a la radiación ultravioleta no elimino y que a su vez producirá un sellado en la superficie de la carne que no permitirá la contaminación con nuevas bacterias. Medios de desagüe dispuestos al fondo del dispositivo de desinfección colectaran el excedente de la solución de quitosano para sus respectivas pruebas de reutilización. In the beginning, the disinfection device is stopped with the entrance and exit doors 1 and 2 open. The iproxl and iprox2 proximity switches corresponding to doors 1 and door 2 respectively indicate that they are open and the disinfection process is It is blocked by the security protocol that it applies every time any of the iproxl or iprox2 switches point open. All these commands are executed from a central processing system that is equipped with a microcontroller programmed for these functions. At this point an alternate protocol verifies the position of the solenoid valve 1 that controls the position of the doors 1 and 2 simultaneously, if the solenoid valve 1 is in the closed position then sends an alarm signal to a control touch screen so that the doors and the pneumatic closing system is verified; If the solenoid valve is in an open position, that is to say that it matches the signal sent by the iprox 1 and iprox 2 switches, then the disinfection process begins. Beef carcasses arrive at the beginning of the disinfection process by means of a rail through which cars are attached to hooks that hold the meat carcasses. Then an electromagnetic fastener catches the hook where the meat or product channel hangs and an electromagnetic pin is deactivated to let said car roll while an infrared sensor monitors that only one car passes at a time; once it detects the passage of a car, it activates the pin again to block the passage of more channels; the fastener then transports the product into the disinfection device moved by a stepper motor 1 controlled by the microcontroller. Once the meat channel is inside the disinfection device two proximity sensors placed inside measure the position of the meat and send adjustment signals to the microcontroller which sends signals to the motor 1 for readjustments. Once the product is in position, the microcontroller sends the solenoid valve 1 to close, which in turn closes the doors, administering a flow of compressed air that sends to a pair of pneumatic actuators placed one on each door, then doors 1 and door 2 they close; The signal of the iprox 1 and iprox 2 sensors is checked and if any of them mark an open position, the process stops and an alarm signal is sent to the touch screen for review, otherwise the process continues. Four UVC lamps placed in each corner of the disinfection device are lit for a period of 90.9 seconds to achieve 99% neutralization of the bacteria, after that the UVC lamps turn off four limit switches distributed in pairs (beginning-end) determine the length of the product from two opposite angles so that with this information a pair of square pipes (one for each pair of end-of-field sensors) run) that have 3 sprinklers installed each can make a vertical sweep from the beginning of the product until the end of the product while a hydropneumatic pump generates a pressure flow of chitosan solution through an electrovalve 2 that opens to allow the passage of the chitosan solution towards the sprinklers that produce a uniform spray pattern on the surface of the product The vertical movement of the square pipes is produced by the motor 2 and step motor 3 respectively; thus generating an antibacterial biofilm that will eliminate bacteria that exposure to ultraviolet radiation did not eliminate and which in turn will produce a seal on the surface of the meat that will not allow contamination with new bacteria. Drainage means arranged at the bottom of the disinfection device will collect the excess of the chitosan solution for their respective reuse tests.
Una vez terminado el barrido de las tuberías en escuadra, estas regresan a su posición inicial y se desenergiza el sistema de desinfección, la electroválvula 1 recibe la señal de apertura y esta a su vez acciona los actuadores neumáticos para que abran las puertas 1 y 2, se verifica que los sensores iprox 1 e iprox 2 se encuentren abiertos y el microcontrolador hace mover el motor 1 para que por medio del sujetador electromagnético el producto sea retirado del dispositivo de desinfección al mismo tiempo que otro sujetador electromagnético atrapa otro gancho con un nuevo producto al inicio del proceso y el pasador electromagnético se desenergiza para dejar pasar dicho producto y el proceso se repite nuevamente.
Once the scan of the square pipes is finished, they return to their initial position and the disinfection system is de-energized, the solenoid valve 1 receives the opening signal and this in turn activates the pneumatic actuators to open doors 1 and 2 , it is verified that the iprox 1 and iprox 2 sensors are open and the microcontroller moves the motor 1 so that by means of the electromagnetic fastener the product is removed from the disinfection device at the same time that another electromagnetic fastener catches another hook with a new product at the beginning of the process and the electromagnetic pin is de-energized to pass said product and the process is repeated again.
