Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a simultaneous command system applied in a pollution monitoring telemeter system and the like.

FIG. 1 is a block diagram showing the configuration of such a telemeter system, in which the central station 1 and slave stations 2 are connected by radio lines through their respective transceivers 3 and 4. Telemeter master station device 5
A telemeter signal is transmitted from the device 7 in response to a polling signal transmitted from the device 7 via the switching device 6, or periodically by a timer or the like of the telemeter device 7 of the slave station 2. The telemeter master station device 5 receives this and provides it to a data processing device 8 such as an electronic computer, where the telemetered data is stored and analyzed.

The central station 1 is also provided with a broadcasting device 9 consisting of a microphone, an audio amplifier, etc., and a command device 11 consisting of a tone transmitting device 10 that sends out a tone signal of an audio signal. Based on the pollution occurrence situation, etc., a simultaneous command such as caution is issued to each pollution source. At this time, the switching device 6 switches the telemeter master station on the assumption that the transmission and reception of telemeter signals is suspended. After switching from the device 5 to the command device 11, the command device 11 is switched to the transmitter/receiver 3.
First, a tone signal is sent to alert the driver, and then a voice command is sent.

This tone signal and simultaneous command are sent to the command receiving station 12.
The information is received by the receiver 13 of each pollution source, and the personnel at each pollution source execute the necessary countermeasures according to the contents of the simultaneous command.

The switching device 6 is controlled by the data processing device 8, and the telemeter master station device 5 and the transceiver 3 are normally connected preferentially.

However, in recent years, with the development of anti-pollution administration,
As the scale of the technical department, which conducts analysis and research of telemetered data, and the administrative department, which carries out simultaneous commands, has expanded, these two departments have been separated organizationally and physically, and the central office 1 and It became necessary to issue simultaneous commands from separate parts, and the configuration of the central station 1 shown in FIG. 1 had the disadvantage that it could not cope with such demands.

The purpose of the present invention is to fundamentally solve such drawbacks of the conventional technology, by separating the central station and the issuing station, communicating between the two stations via a transmission line, and transmitting the information from the issuing station to the central station all at once. This provides an extremely rational simultaneous command method for transmitting commands.

The details of the present invention will be explained below with reference to the block diagram of FIG. 2 showing an embodiment.

In the figure, the issuing station 21 is separate from the central station 1.
The station 21 is equipped with a broadcasting device 9 and a first signal transmitting device that transmits a tone signal and a switching request signal such as an audio frequency signal, or only a tone signal, and receives a response signal from the central station 1. A command device 11 composed of a transmitter/receiver device 22 is provided, and at the same time a data monitor device 23 is provided, and these and the central office 1 are connected by transmission lines 24 and 25 such as wired lines. .

Further, the central office 1 is provided with a second signal transmitting/receiving device 21 connected to the transmission line 24 via a switching device 26, and thereby transmitting and receiving signals with the first signal transmitting/receiving device 22. It has become a thing.

Note that the data processing device 8 and the data monitoring device 2
3 through a transmission line 25, so that the telemetered data can be immediately displayed on the data monitor device 23.

Therefore, in the issuing station 21, when a simultaneous command is required based on the display on the data monitor device 23, when the first signal transmitting/receiving device 22 sends out a tone signal or a switching request signal, this signal is sent to the second signal transmitting/receiving device 27. This received output is given to the data processing device 8, and the device 8 gives a switching command signal to the switching device 26 and sends a switching command signal to the second signal transmitting/receiving device 27 on the premise that transmission/reception of the telemeter signal is suspended. In response, a response signal sending command signal is given.

Then, the switching device 26 switches to the telemeter master station device 5.
and the transmission line 24, and the transmission line 2
4 to the transmitter/receiver 3, a response signal is sent from the second signal transmitter/receiver 27 to the transmission line 24, which is received by the first signal transmitter/receiver 22, and this received output indicates that switching has been completed. will be carried out.

Therefore, knowing that a simultaneous command is possible at the issuing station 21, the first signal transmitting/receiving device 22 transmits a tone signal and the broadcasting device 9 transmits a simultaneous command, so that these transmit the transmitter/receiver 3 of the central station 1. Sent via

In addition, at the issuing station 21, the sending signal is monitored by a VU meter, etc., and at the central station 1, the data processing device 8 records that the simultaneous command has been issued.

In addition, as the switching request signal from the issuing station 21 and the response signal from the central station 1, pulse signals, frequency shift signals, etc. may be used depending on the conditions. Various modifications are possible, such as a combination of the above, a frequency shift signal, a pulse signal, or the like as a calling signal, and a calling signal receiving device may be provided in the command receiving station 12 accordingly.

As is clear from the above explanation, according to the present invention, the issuing station is separated from the central station, and the two stations are connected via a transmission line, so that the administrative department that issues simultaneous commands and the analysis of telemetered data It is now possible to separate geographically from the technical department that conducts
Moreover, since there is no operational conflict between the two departments, a great effect can be obtained as a simultaneous command method for pollution monitoring telemeter systems, etc.
