Embodiment
Please be earlier with reference to Fig. 1 be a preferred embodiment of the present invention functional block diagram, and Fig. 2 be the system architecture diagram of a preferred embodiment of the present invention.The present invention is a kind of signal detecting system that utilizes the telephone wire transmission, comprises an arrangement for detecting 10, an alarm device 30 and a telephone line 50.Wherein, arrangement for detecting 10 is to utilize the measured signal of telephone line 50 transmission arrangement for detecting 10 to alarm device 30.In addition, be to be applied in hotels and restaurants' industry in the present embodiment.Arrangement for detecting 10 is mounted in each room in hotel, and 30 of alarm devices are before group is located at the switch 70 of phone exchange line case 90.
In the present embodiment, each arrangement for detecting 10 all includes a radio frequency receiver 11, a filter 12, a signal amplifier 13, connects conversion receiver 14 and a quasi converter 15 always.Wherein, radio frequency receiver 11 is to receive an external radio frequency signal S1, and the frequency range of receiving of this outside radio-frequency (RF) signal S1 is 30MHz to 6GHz.Filter 12 is that outside radio-frequency (RF) signal S1 is carried out filtering, and filtered radio-frequency (RF) signal S2 is sent to signal amplifier 13.Signal amplifier 13 is with filtered radio-frequency (RF) signal S2, and the radio-frequency (RF) signal S3 through after the signal processing and amplifying exports direct conversion receiver 14 to.Directly conversion receiver 14 is the radio-frequency (RF) signal S3 that receive after processing and amplifying, and this radio-frequency (RF) signal S3 is directly changed into baseband signal S4.Position quasi converter 15 is that this baseband signal S4 is compared with an accurate default value, and works as baseband signal S4 greater than the accurate default value in position, then exports this baseband signal S4, and is sent to alarm device 30 via telephone line 50.
30 groups of alarm devices are provided with a controller 31, an and attention device 32.Wherein, controller 31, and attention device 32 be to be electrically connected.In addition, if there is abnormal signal to result from the zone of being detected, then arrangement for detecting 10 transmits the controller 31 of a warning signal to alarm device 30 by telephone line 50 immediately, and then triggers attention device 32.
In the present embodiment, attention device 32 adopts buzzer 32, to produce a warning tones; Certainly also can adopt other equivalent device.In addition, display 33 is to adopt LCDs 33, directly to show the zone of institute's abnormal signal; In like manner, also can utilize the device of LED or other equivalence.Thus, can reach the effect of acousto-optic warning.
Therefore, (as the signal of taking on the sly of pinhole camera) is transmitted to the zone of being detected can to detect by the present invention whether abnormal signal is arranged, and show or the give a warning mode of sound of buzzer 32 is informed the staff with LCDs 33, in order to do directly searching particular room, to save time and manpower.
In above-mentioned, arrangement for detecting 10 of the present invention is also organized and is provided with a microprocessor 15, reaches a power control circuit 16.Wherein, microprocessor 15 is to be electrically connected to power control circuit 16.Alarm device 30 of the present invention is also organized and is provided with a power-supply controller of electric 37, reaches an accurate adjuster 36.When arrangement for detecting 10 faults or abnormal operation, the staff can be closed long-range arrangement for detecting 10 via telephone line 50 at alarm device 30 ends, to reach the purpose of two-way control.In addition, also can utilize the position of adjusting the accurate adjuster 36 in position accurate, to change the sensitivity of arrangement for detecting 10.
Among the present invention, the controller 31 in the alarm device 30 is to be connected to a main frame 35 via a RS-232 connectivity port 34, and can see through application software operation, to note down the status data of each arrangement for detecting 10.In addition, also can send the real-time status of each arrangement for detecting 10 to long-range, so that the purpose of remote monitoring to be provided via the internet.
In addition, referring again to the system architecture diagram of Fig. 3 for another preferred embodiment of the present invention, the operating principle of present embodiment and last embodiment are similar, and unique difference is the structure difference of telephone system, but also can reach identical effect.Last embodiment utilizes switch 70 tap extensions, and present embodiment then is telephone line 50 direct tap extensions, and need not see through switch 70.In the present embodiment, a telephone line 50 at most only can four telephone sets of tap.Be general family or the company of being applied in the present embodiment, at first, arrangement for detecting 10 be mounted to the fixed point of desire detecting, and be connected to telephone line 50, again alarm device 30 is mounted to phone exchange line case 90 before.Thus, whether the staff produces abnormal signal in telecommunications room can be monitored all rooms, to reach the purpose of detecting.
