Description

[Detailed Description of the Invention] This invention relates to an automatic measuring device. More specifically, in an automatic measuring device in which measured output is recorded on a recorder, and the measured output is called out by a telemeter system and collected on a computer, etc., a relay is provided that operates in response to a signal calling up the measured output, and , the recorder is a multi-channel recorder with at least two channels;
The present invention relates to an automatic measuring device in which channels in which measured outputs are recorded can be switched by operating the relay.

Automatic measuring devices used for pollution monitoring, etc.
The measurement output is recorded on a recorder attached to the measurement device, and is also collected on a computer or the like by a telemeter system. The data recorded on the recorder and the data recorded on the computer etc. are often compared to check for errors.
Conventionally, this verification has been difficult and time-consuming. The reason for this was that it was not possible to tell just by looking at the data which part of the continuous data recorded on the recorder corresponded to the data collected on a computer, etc., and the time scale had to be tracked in order.

This idea was made with the aim of solving the above-mentioned problems, and was designed to record the measurement output so that the data collected on a computer etc. can be clearly distinguished from the other data parts. The purpose is to provide an automatic measurement device that records information.

This invention will be explained in detail below based on the embodiments shown in the figures.

1 is an embodiment of the automatic measuring device of this invention. The analysis section 2 measures the hydrocarbon concentration in the atmosphere,
The instantaneous value is output every moment. The averager 3 is an integrator and outputs an average value of the instantaneous values. 4 is a two-color dot type recorder having two channels, the dot color of the first channel is blue, and the dot color of the second channel is blue.
The dot color of the channel is red. The output of the averager 3 is connected by the contact 5a of the relay 5 to the input 4a of the first channel or the input 4b of the second channel of the recorder 4. When the relay 5 is not activated, the input 4a of the first channel;
When activated, it is connected to the input 4b of the second channel.

6 is a telemeter system, 7 is a computer, and 8 is a timer. A call signal for the automatic measuring device 1 is generated every hour by the timer 8, and the switches _S1 and _S2 are closed. When switch S ₁ is closed, the average value is read into computer 7 via transmission line 9 . Furthermore, when the switch _S2 is closed, the relay 5 of the automatic measuring device 1 is activated via the transmission line 10.

Therefore, the average value, which is the measured output, is normally recorded on the first channel of the recorder 4, but when it is being read into the computer 7, the relay 5 is activated, so it is recorded on the second channel. In other words, the data in the portion that is not collected by the computer 7 is recorded in blue, and the data in the collected portion is recorded in red. Therefore, when later comparing the data collected on the computer 7 with the data recorded on the recorder 4, it is only necessary to check the red part, and the work efficiency is significantly improved compared to the conventional method.

In addition, the closing time of Switch S ₂ is short,
Therefore, if relay 5 operates for a short time and the red part cannot be distinguished, relay 5
Assuming that is an off-delay timer relay that is activated by the momentary ON of switch _S2 and continues to operate for a certain period of time even if switch _S2 is opened, the called data portion can be clarified.
In addition, when the automatic measuring device 1 is equipped with a programmer (not shown) for program-controlling the analysis section 2, the relay 5 is activated and self-maintained by instantaneously turning on the switch _S2 , and after a predetermined time, the programmer is activated. It may also be turned off.

In the above explanation, for convenience of explanation, the recorder 4 was explained as a two-color dot type recorder having two channels. However, in an actual atmospheric hydrocarbon concentration measuring device, instantaneous methane concentration, instantaneous non-methane hydrocarbon concentration, etc. Four measurement outputs should be recorded on the recorder: the average value of methane concentration and the average value of non-methane hydrocarbon concentration, of which this invention is applied to the average value of methane concentration and the average value of non-methane hydrocarbon concentration. In the end, a 6-channel recorder is actually used.

As explained above, according to the automatic measuring device of this invention, it can be seen at a glance which part of the measurement output data recorded on the recorder has been collected on a computer or the like. Therefore, data in the recorder can be compared with data recorded on a computer or the like very easily. Moreover, even if the computer or the like reads the measurement output irregularly for some reason, this fact will be clearly shown on the recorder, so there is a double check effect.
