1．能正常计时。显示模式分为24小时制和12小时制。其中12小时制须显示上、下午。“时”、“分”、“秒”都要显示。 2．具有快速校准时、分、秒的功能。手动校准，用一个功能键选择校时、校分功能，用另一功能键调校对应时、分数值。 3．整点自动报时。在离整点10s时，便自动发出鸣叫声，步长1s，每隔1s鸣叫一次，前四响是低音，最后一响为高音，最后一响结束为整点。 -1. To resume normal time. Display mode is divided into 24-hour and 12-hour clock. Including 12-hour clock to be displayed on the afternoon. "Time", "sub", "seconds" must be displayed. 2. Fast calibration, minutes and seconds functions. Manual calibration, using a function button to select the school, the school hours functions, corresponding with another function key set, the score values. 3. The whole point of automatic timekeeping. The whole point away from the 10s, they automatically send calls, step 1s, at intervals of 1s tweet once, the first four bass sound is the last one for the treble ring, ring the end of the last one for the whole point.

摘 要：建立了几个军事短波通信系统仿真模型，并简要叙述了军事短波通信系统中跳频、扩频的干扰方程。文章给出了仿真物理结构图以及功能模块图，也给出了军事短波通信抗干扰性能仿真评估的指标，提出了利用云模型及云不确定性推理对仿真结果进行评估，并给出了干扰和无干扰条件下军事短波通信的抗干扰性能评估结果。-Abstract: A number of military HF communications system simulation model, and a brief description of the military short-wave frequency-hopping communication systems, spread spectrum interference equation. In this paper, simulation of the physical structure and function module map also gives the military a short-wave communications simulation to assess anti-interference performance indicators, the use of cloud model and the cloud of uncertainty reasoning to assess the simulation results are also given interference and non-interference under the conditions of military HF communication the results of the assessment of anti-interference performance.

利用通讯模块进行数据通信，就是将数据体作为短消息的内容，从发送方的通讯模块发送出去，通过短消息中心进行转发，接收方通讯模块收到此短消息后即存储在SIM卡上，模块外接的控制器（如单片机、计算机等）从模块中读取短消息后，根据需要将无用的信息去除，取出有效信息，然后将SIM卡中的短消息删除，这样就完成一次单向数据的传输。利用通讯模块的短消息方式实现数据的发送和接收具有通信成本低、系统容量大、抗干扰能力强等优点，而且短消息经过服务中心再到达目的地的特点使通讯模块无需24小时开机，降低了系统功耗，特别适合遥控、遥测、远程信息处理和通信等领域。-GSM
