WBJ—1无线报警器主要用于工业检测和防灾、防盗报警等领域,报警器接收机十路终端除能显示报警部位和发出告警信号外,均具有报警记忆功能。目前国内同类产品尚不能有效地抑制火花干扰,存在产生“误报”问題。WBJ—1无线报警器采用了“分时控制、等幅处理”的抑制干扰方案。经试验表明,该机在抗火花干扰能力方面成效显著。另外由于该机选用了模拟通信体制和调幅方式,使其具有成本低廉,结构简单,调试方便等优点。
WBJ-1 wireless alarm is mainly used in industrial detection and disaster prevention, burglar alarm and other fields, the alarm receiver ten terminals in addition to the display of alarm parts and alarm signals, the alarm memory function. At present, similar products in our country can not effectively suppress the spark disturbance, resulting in the problem of “false positives”. WBJ-1 wireless alarm uses a “time-sharing control, equal amplitude processing” suppression interference program. The test shows that the machine has achieved remarkable results in the anti-spark interference ability. In addition, as the aircraft used analog communication system and amplitude modulation method, it has the advantages of low cost, simple structure, easy debugging.
