新一代微机控制的数字式DWA系列无线报警器已由615所研制成功。 在该系列报警器的接收机和发射机中,均采用了高性能的单片微型计算机,在外围电路和软件控制程序的配合下,能完成数据编码、纠错码、伪随机跳时、存贮显示和功能控制等功能,系统工作稳定可靠,虚警概率远远低于一般模拟式无线报警器。 该报警器可在每天晚上定时提供一次系统无线自检服务,使用、安装、维护方便,机内可加装镉镍电池组,平时用交流市电自动充电,一旦市电中断,可自动切换到直流供电。
A new generation of computer-controlled digital DWA Series wireless alarm has been developed by the 615. In the series of alarm receiver and transmitter, are used in high-performance single-chip microcomputer, in the peripheral circuit and software control program with the ability to complete data encoding, error correction code, pseudo-random jump, save Storage display and function control and other functions, the system is stable and reliable, false alarm probability is much lower than the general analog wireless alarm. The alarm can be provided every evening at a regular wireless system self-test service, easy to use, install, maintain, the machine can be equipped with nickel-cadmium battery pack, usually with AC mains automatic charging, once the mains interruption, can automatically switch to DC power supply.
