Abstract

PURPOSE:To enable transfer of environmental information such as video, voice, temperature, and humidity by a public telephone line. CONSTITUTION:The environmental information collected by a camera 2, microphone 3, temperature detecting sensor 4, and humidity detecting sensor 5 in an observation objective point 1 is converted into data suitable for a public telephone line 16 by a picture band compression transfer device 6 and a data module 7 and transmitted. On the reception side, the original environmental information is reproduced by a data module 8 and a picture band compression transfer device 9 to be reproduced by a monitor 10, speaker 11, temperature controller 12, and humidity controller 13.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an environmental information transmission system.

[0002]

2. Description of the Related Art A conventional transmission system is a system for transmitting an image and a sound, which are environmental information obtained at an observation target point, to an observation point by using a dedicated line and reproducing the information to monitor it constantly or as needed.

[0003]

In such an environment information transmission system, since a dedicated line is used,
There are drawbacks that the line cost becomes high and only image and sound can be transmitted as environmental information.

[0004]

The system of the present invention comprises a camera for taking a still image, a microphone for collecting voice, a first sensor for detecting temperature, and a second sensor for detecting humidity. An image band compression transmission device for band compression encoding and multiplexing both the still image and the voice signal, and the multiplexed signal and both detection signals of the first and second sensors can be connected to a general public telephone line. A data module for converting the data into a different data format and transmitting the data to the public telephone line, and reproducing the multiplexed signal and the detection signals of the first and second sensors from the data received from the public telephone line. A data module, an image band compression transmission device for reproducing both the still image signal and the audio signal from the reproduced multiplexed signal, and the reproduced still image and the audio signal. And a monitor and a speaker for live, control the temperature and humidity in response to the detection signal of the first and second sensors reproduced, and a receiving apparatus having a control means for adjusting.

[0005]

The present invention will be described below with reference to the drawings.

FIG. 1 shows a block diagram of an embodiment of the present invention. A transmitter 1 installed at an observation target point has a camera 2 for photographing, a microphone 3 for collecting sound, and an image band compression for encoding and multiplexing both signals of a voice and a still image and converting them into digital signals. Transmission device 6, temperature detection sensor 4 for detecting temperature, and humidity detection sensor 5 for detecting humidity
And data to be connected to the general public telephone line 16 by converting the digital signals from the image band compression transmission device 6, the temperature sensor 4, and the temperature sensor 5 into a data signal of a rate that can be transmitted through the public telephone line. The module 7 and the module 7 are included.

The camera 2 captures a still image of the destination,
The microphone 3 collects the voice at the destination and sends both signals to the image band compression transmission device 6 to obtain a coded, band compressed, and multiplexed digital signal.

The temperature detection data from the temperature detection sensor 4 and the humidity detection data from the temperature detection sensor 5 are input to the data module 7, converted to be compatible with the interface on the line side, and then transmitted to the line 16. To be done.

In the receiving device 15 for receiving this, the data module 8 is interface-converted into data suitable for the image band compressing and transmitting device 9 and then input to the image band compressing and transmitting device 9. The image band compression transmission device 9 separates and reproduces audio and video signals from the band compression coded multiplexed signal and sends them to the monitor 10 and the speaker 11, respectively, to reproduce audio and still images.

The temperature detection signal data and the humidity detection data are interface-converted by the data module 8 so as to be compatible with the control device 14, and then input to the control device 32 for adjustment of each of the temperature controller and the humidity controller 13. Is generated to control the temperature controller 12 and the humidity controller 13.

[0011]

As described above, according to the present invention, it is possible to apply to environment information transmission in which the change with the passage of time is relatively gradual, and use a general public telephone line to lower the line than the conventional system. Information can be transmitted at a cost, and the temperature and humidity at the observation point can be reproduced.
