Abstract

Un aparato para controlar un proyector láser para operar, comprendiendo el aparato: un módulo (1001) de obtención configurado para obtener un parámetro operativo del proyector láser en operación, antes de que se encienda un dispositivo láser del proyector láser; un módulo (1002) de evaluación configurado para hacer una comparación del parámetro operativo obtenido con un parámetro preestablecido, y para evaluar si el parámetro operativo es normal o anormal, en el que el parámetro predeterminado es un parámetro del proyector láser que está operando normalmente; y un módulo (1003) de determinación para detener una operación de arranque del proyector, si determina que el proyector láser falla, y para emitir una información de fallo, cuando el módulo (1002) de evaluación evalúa que el parámetro de operación es anormal; y para decidir aligerar el dispositivo láser cuando el módulo (1002) de evaluación evalúe que el parámetro de operación es normal, en el que la información de fallo se determina de acuerdo con el resultado de dicha comparación si se determina que el proyector láser falla.
