    • Alarms are often required on various vehicles and equipment such as fork lifts, dump trucks, bulldozers, etc. An alarm is disclosed controlled by a microprocessor, which is an integral part of the basic circuit. The microprocessor is relied upon for adjusting alarm output based on source voltage, time of day, ambient noise, ambient frequencies, and ambient temperature. Additional features include sensing the alarm's own output to adjust alarm output in a feedback control loop, alarm self diagnosis using a current sensor, and using the microprocessor to operate a digital radio, such as Bluetooth, for intelligent alarm communication into a monitoring system for vehicle alarm status.
    • 各种车辆和设备,例如叉式升降机,自卸车,推土机等通常需要报警。由微处理器控制的报警是基本电路的组成部分。 依靠微处理器调整基于源电压,时间,环境噪声,环境频率和环境温度的报警输出。 附加功能包括检测报警自身的输出,以调节反馈控制回路中的报警输出,使用电流传感器进行报警自诊断,以及使用微处理器操作诸如蓝牙的数字无线电,将智能报警通信转换为车辆监控系统 报警状态。

    • Alarms are often required on various vehicles and equipment such as fork lifts, dump trucks, bulldozers, etc. An alarm is disclosed controlled by a microprocessor, which is an integral part of the basic circuit. The alarm has a flat diaphragm, and a novel acoustic lens. The acoustic lens is constructed such that sound emanating from the center of the diaphragm has a direct path to the outside of the alarm. Sound produced around the periphery of the diaphragm must pass through a path containing switchbacks, that serve as an acoustic delay line, so this sound is delayed in exiting the alarm. The result is an alarm that with full sound in the important regions such as behind and to the side rear of the vehicle, but is very quiet for the operator or driver of the vehicle. The microprocessor is relied upon for adjusting alarm output based on source voltage and varying the signal based on ambient noise, as well as specific signals for particular applications.
    • 各种车辆和设备,例如叉式升降机,自卸车,推土机等通常需要报警。由微处理器控制的报警是基本电路的组成部分。 报警器有一个平坦的隔膜和一个新的声学透镜。 声透镜被构造成使得从隔膜的中心发出的声音具有到达警报器外部的直接路径。 围绕隔膜周围产生的声音必须通过包含折返的路径,作为声学延迟线,因此在退出报警时延迟声音。 结果是在车辆的后方和后方的重要区域具有完整的声音的报警,但对于车辆的操作者或驾驶员来说是非常安静的。 微处理器依赖于基于源电压调整报警输出,并根据环境噪声改变信号,以及针对特定应用的特定信号。
