Intelligent vehicle meter

Abstract

An intelligent vehicle meter includes an associative processing unit and a signal processing unit connecting to various modules to process related signals. Through a measurement module and an accelerometer module physiological conditions of an exerciser and exercise intensity can be obtained to generate a control signal to be sent to a control module. Hence a corresponding control measure can be made immediately by the control module according to exerciser's conditions to actively change use intensity of the exercise equipment to enable the exerciser to do exercise under the optimal condition to protect the health and safety of the exerciser.

1 . An intelligent vehicle meter mounted by an exerciser onto a moving exercise equipment which has an external input device and an associative processing unit which receives input signals from the external input device, comprising a signal processing unit, a display device, a measurement module, an accelerometer module and a control module;
 wherein the signal processing unit receives processing signals from the associative processing unit and sends a feedback signal to the associative processing unit, the external input device receives entering of exerciser's physical data and setting of system parameters, the display device is connected to the signal processing unit to display system conditions and parameter setting, the measurement module measures physiological conditions of the exerciser and transmits to the associative processing unit, the accelerometer module measures acceleration and derives speed and a position vector through integration calculations to get kinetic energy and potential energy to obtain alterations of total mechanical energy, and convert to exercise intensity of the exerciser and send to the associative processing unit, the control module changes use intensity of the exercise equipment, and the signal processing unit receives the physiological conditions and the use intensity of the exerciser from the associative processing unit to generate a control signal which is sent to the control module to actively change the use intensity of the exercise equipment.   
   
   
       2 . The intelligent vehicle meter of  claim 1 , wherein the intelligent vehicle meter is detachable from the exercise equipment and portable to be carried by the exerciser so that that the accelerometer module is allowed to measure the acceleration of the exerciser and get the number of walking steps taken by the exerciser by converting alterations of the acceleration.
