Abstract

PURPOSE:To surely transmit a message when a receiver comes back even during the absence of the receiver by providing a character signal generating part to generate a character signal corresponding to the state of a specific object by receiving output from a sensor, and a delivery part to send the character signal from the character signal generating part via a telephone circuit. CONSTITUTION:When abnormality is detected by the sensors 1 and 2, the detecting signal is processed by a central processing part 4, and the character signal representing the message corresponding to the information is generated from a character signal synthesizing part 7. For example, when a fire is detected, the character signal representing the message such as 'A fire broke out.' etc., is generated, and it is supplied to a facsimile signal synthesizing part 7. A facsimile signal is synthesized at the part, and it is sent to a facsimile terminal equipment 9 with a telephone number set in advance via an NCU8, then, the message is transmitted to the receiver in character.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring device using a telephone line.

[Conventional technology] Traditionally, fire sensors,
2. Description of the Related Art There is a monitoring system that receives signals from various sensors such as an intrusion sensor and sends prerecorded voice to a receiver of an arbitrary telephone number to contact the receiver.

[Problems to be solved by the invention] Since the above-mentioned system transmits voice, the message cannot be transmitted when the recipient is absent, no record of the reception is left, and it is difficult to make the synthesized voice clear. There are drawbacks such as leakage of information to third parties.

The present invention eliminates each of the above drawbacks by transmitting information using character signals.

[Means for Solving the Problems] The present invention provides a character signal generation section that receives outputs from each sensor and sends out character signals in accordance with the outputs, and sends out these character signals via a telephone line. This allows information to be sent in text format.

[Embodiment] In the drawings, 1 and 2 are sensors for crime prevention or disaster prevention, 3 is a sensor input unit, 4 is a central processing unit consisting of a CPU, etc., and 5 is a character signal representing a message in response to a signal from the sensor. This is a character signal generator that generates a character signal. 6 is a character signal sending section, which includes a facsimile signal synthesis section 7 and an NCU (
(Network control circuit) 8. 9 is a receiving facsimile terminal.

In the above configuration, when an abnormality is detected by the sensors 1 and 2, this detection signal is processed by the central processing section 4, and a character signal representing a message according to this information is generated from the character signal synthesis section 7.

For example, when a fire is detected, a character signal representing a message such as "A fire has broken out" is generated, and this is supplied to the facsimile signal synthesis section 7. There, the facsimile signals are combined and sent via the NCU 3 to the facsimile terminal 9 having a preset telephone number, and the message is transmitted to the recipient in text.

Note that the sending unit is not limited to facsimile, and may also use telex.

[Effects of the Invention] According to the present invention, since the information detected by the sensor is sent in the form of text, a record of the reception remains, and even when the recipient is away, the message can be reliably conveyed when the recipient returns home. Furthermore, since voice is not used, it is possible to eliminate the inconvenience of information being overheard by a third party and being leaked.

Furthermore, since no voice line is used, the reception rate on the receiving side is high, and the probability that the message can be transmitted immediately is high.
