Abstract
The utility model discloses a prevention and control monitoring instrument and pertains to an equipment of signal detection, in particular to an equipment of wireless remote control signal detection. The utility model is in characterized that the structure of the prevention and control monitoring instrument is that a 315M and a 433M receiving circuit are respectively connected with an A/D converting circuit of a single-chip microcomputer through a signal amplification circuit and then connected with a CPU. The CPU connects a signal strength display instrument and an indicating light. A setting circuit is connected with the CPU and the CPU is connected with a flashing alarm device and a sound alarm device. As a wide-frequency receiver is adopted by the monitor of the prevention and control monitoring instrument, the illegal remote control signals can be sensitively monitored, and a sound and light alarm device can be activated at any time according to the strength of the signal and setting values to remind people to take actions such as the emission of the jamming signals. After the utility model been arranged adjacently to the remote control equipment that protected the disturbance of the illegal remote control signal can be effectively prevented and the normal working of the equipment can be guaranteed.
Description
Affiliated technical field
The utility model belongs to signal detection apparatus, particularly the wireless remote control signal detection apparatus.
Background technology
The visual plant that uses in the actual life is a lot, some visual plant is often illegally installed remote control equipment attempt by lawless people it is carried out remote control reach its illegal objective, does not still have at present and can effectively carry out device for monitoring to this illegal remote control.
Summary of the invention
The purpose of this utility model provides a kind of technical scheme of the novel prevention and control monitor that can monitor illegal remote signal.
The technical solution of the utility model is, a kind of prevention and control monitor, its structure is: 315M, 433M receiving circuit are connected on the CPU through the A/D change-over circuit that signal amplification circuit is connected to single-chip microcomputer respectively, CPU connects signal intensity Displaying Meter and pilot lamp, initialization circuit is connected on the CPU, and CPU connects flash alarm and voice guard.
Described single-chip microcomputer adopts the ATMEGA8-32 chip.
Described single-chip microcomputer adopts the ATMEGA8 chip, 23,24 pin of chip are signal input part, 9,10,16,17,18,19 pin connect the setting button, 25,26,27,28 pin connect Displaying Meter and pilot lamp, 2,3,4,5,6,11,12,13, pin connects each electrode of charactron, 14,15 pin connect flash alarm and voice guard.
Described signal intensity Displaying Meter, the display circuit that is connected charactron S by three groups of amplifying triode Q is formed, and its circuit of described pilot lamp connects light emitting diode D10 by triode Q and forms.
Principle of work of the present utility model is, this monitor is sent into single-chip microcomputer after by 315M receiving circuit and 433M receiving circuit the wireless remote control signal of receiving being amplified, in single-chip microcomputer by entering in the CPU after the A/D conversion.CPU shows instrument with signal by three figure places and demonstrates signal intensity, and functional indicator light is indicated respectively duty and set condition.Set the adjustment circuit and can be set at the comparator circuit that a certain numerical value is delivered to CPU as required, when signal intensity reaches setting numerical value, the CPU output alarm signal, one the road drives alarm lamp, carry out flashing light alarm, another road drives hummer sound that gives the alarm, and reminds the related personnel to note.
The prevention and control monitor that the utility model provides is because monitor has adopted bandwidth is the illegal remote signal that monitors that the 315M of 10M and two wideband receivers of 433M can be sensitive, at any time can show the intensity of this signal and can start sound and light alarm signal reminds people automatically and take measures, for example send undesired signal etc. according to setting value.It is installed near the interference that just can effectively prevent illegal remote signal the remote control equipment that needs protection, assurance equipment operate as normal.
