Abstract

método e sistema de controle para detectar a força de frenagem de um veículo. a presente invenção se refere a tecnologias de proteção de operação de veículo e fornece um método e sistema de controle para detectar uma força de frenagem de um veículo. o método de controle inclui medir em tempo real por dois ou mais acelerômetros e determinar uma desaceleração prática do veículo; determinar se uma força de frenagem prática atende a uma exigência de frenagem de acordo com a desaceleração prática; e tomar uma medida de proteção de emergência após determinar que a força de frenagem prática do veículo é insuficiente. medindo-se diretamente a desaceleração prática do veículo com o uso dos acelerômetros, a presente invenção tem uma estrutura simples e baixa ocorrência de erros e é fácil de implementar. a presente invenção combina o monitoramento da força de frenagem prática do trem com a proteção da velocidade do trem e reforça as funções de um sistema de controle automático do trem (atc), garantindo de maneira eficaz a segurança da operação do trem.method and control system for detecting the braking force of a vehicle. The present invention relates to vehicle operation protection technologies and provides a method and control system for detecting a braking force of a vehicle. the control method includes real-time measurement by two or more accelerometers and determining a practical vehicle deceleration; determine whether a practical braking force meets a braking requirement according to practical deceleration; and taking an emergency protective measure after determining that the vehicle's practical braking force is insufficient. By directly measuring the practical deceleration of the vehicle using accelerometers, the present invention has a simple structure and low error occurrence and is easy to implement. The present invention combines practical train braking force monitoring with train speed protection and enhances the functions of an automatic train control (ATC) system, effectively ensuring the safety of train operation.
