Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention is intended to reduce the labor of operators during daily patrols in chemical, textile, petroleum, and other production plants, and to collect collected data. This invention relates to a data collection device for plant patrol that is used for effective utilization.

<Conventional technology> Equipment in chemical, textile, petroleum, etc. plants.

Various measuring instruments are installed to understand the status of equipment and processes and quickly detect abnormalities.

Some of these measuring instruments are centrally monitored, or due to equipment costs, pressure gauges, etc.
Many measuring instruments such as glass tube flowmeters, liquid level gauges, and rod thermometers are on-site indicating instruments located in on-site installation rooms, so operators must patrol them on a daily and regular basis. Is there a need to monitor it?

In addition, since there is no perfect measurement method for inspection items such as corrosion, abnormal noises, and leaks, detection of these items must rely on the human senses.From this point of view, operators' patrols are This is an essential task for management.

<Problem to be solved by the invention> However, in recent years, due to the decrease in the working population and the rise in labor costs, the number of general operators has tended to decrease.

As a countermeasure to this problem, it may be possible to have a small number of people patrol a large number of plants.If this is done, the area in which the operators are responsible will become wider, which may dilute plant-specific information and reduce the ability to identify abnormalities. This poses a problem in that the safety and normal operation of the plant are affected.

In addition, in addition to patrolling and reading data, operators often need to write the data into a ledger, and furthermore, it is difficult to simply manage and check the data collected in this way. In order to make effective use of the data by grasping its trends and integrating it with other information, it is necessary to input the data into various computers.

In this regard, it has also become known to utilize portable data collection devices powered by a key using a small storage medium such as an IC card.

However, such work places a considerable burden on the operator, and when key input is performed manually, there is a high possibility of erroneous input. There was also the problem that it could not be considered.

Furthermore, the above method has a problem in that it only has a data collection function and does not have a warning function such as abnormality determination.

In view of the above problems, the present invention reduces the labor of plant patrol, effectively utilizes accurate data, and
Another object of the present invention is to provide a data collection device for plant patrol that can quickly determine abnormalities.

<Means for Solving the Problems> In order to achieve the above object, the present invention provides a voice input device that inputs data as voice, a voice recognition device that recognizes the input voice, and a voice recognition device that detects abnormalities in the recognized data. The configuration includes an alarm device that determines the presence or absence of an abnormality and issues an alarm when there is an abnormality, and a storage device that stores recognized data.

Furthermore, the above configuration is configured to include a speech synthesis device that synthesizes data recognized by the speech recognition device into a synthesized speech, and a synthesized speech output device that outputs the synthesized synthesized speech.

Furthermore, it is preferable to integrate all of these devices into a portable device.

Alternatively, the audio input device and the audio output device may be portable, the other devices may be stationary, and a wireless transmitting/receiving device for transmitting and receiving data between the two may be provided.

<Operation> According to the above configuration, when the operator reads the data out loud from each measuring instrument, the voice input device inputs the data as voice, and the voice recognition device reads the input voice. The alarm device determines whether or not there is an abnormality in the recognized data, and outputs an alarm if there is an abnormality.
Operators can know whether an abnormality has occurred or not. Also, the recognized data is stored in the storage device.

Further, the voice synthesizer synthesizes the recognized data into a synthesized sound, the voice output device outputs the synthesized voice, and the operator confirms whether the read data has been input correctly.

Furthermore, since all of these devices are integrated and portable, all work can be completed on site.

Alternatively, if the voice input device and the voice output device are portable and the other devices are stationary, and a wireless transmitter/receiver is provided to transmit and receive data between the two, only the voice input device and the voice output device can be used. , you can carry it to the site and complete the entire work.

<Examples> Below, examples according to the present invention will be explained based on FIGS.
It is not limited to the following examples.

First, a first example will be explained.

The system will be described with reference to FIG.

The audio input device l consists of a sound collection microphone and an amplifier.

The microphone may be of any type, such as a condenser microphone, but it is desirable to have a highly durable one, as it will be used outdoors, in dusty, hot, humid, and rainy conditions.

Furthermore, since there are many equipment in the surrounding environment that generate noise, such as pumps and blowers, it is desirable to use a microphone with strong directivity and a narrow band.

The speech recognition device 2 compares and recognizes words or numerical data input from the speech input device 1 with registered words. More specifically, the input speech is analyzed, the recognition parameters representing the characteristics of the speech pattern are extracted, and the parameters are compared with the registered characteristic pattern parameters of the recognition target word to find the closest recognition target word. select. Examples of the matching method include a linear matching method and a dynamic matching method.

In addition, in order to store it in a portable box (described later), we use a board-type recognition device, and by organizing and limiting the words used, we are able to make the device smaller, lighter, and have a higher recognition rate. Realize. The number of words to be used, including numerical words, will vary depending on the usage situation, but it will range from several tens to hundreds.

Naturally, it is assumed that the input is not as a sentence but as a word, but depending on the available memory capacity, there is no problem in adopting the input as a sentence.

The recognized signals in the speech recognition device 2 are temporarily stored and synthesized into a synthesized speech through the speech synthesis device 3.

The speech synthesis device 3 converts into speech signals recognized by the speech recognition device 2, alarm signals output by an alarm device 5 to be described later, and equipment abnormality signals such as insufficient charging or failure output from the control device 7. A signal is sent to the audio output device 4. Like the speech recognition device 2, this speech synthesis device 3 also uses a board type device for the purpose of miniaturization and portability, and is housed in a portable box to be described later.

The voice output device 4 consists of a speaker and its amplifier, outputs the synthesized sound synthesized by the voice synthesizer 3, notifies the input speaker, and confirms that the input information is correct after being confirmed by the input speaker. If recognized, this information is sent to the alarm device 5 and storage device 6, which will be described later.

The device is preferably of the earphone or headphone type in order to transmit synthesized speech without being affected by external noise or noise.

The alarm device 5 processes input and confirmed plant data, and after determining an abnormality, outputs an alarm if there is an abnormality.

In addition to determining the upper and lower limits, which are conventionally carried out by patrollers, the abnormality determination method uses the capabilities of a microcomputer-based determination device to set separate thresholds based on trends in past data. Alternatively, trend value management can also be realized by moving the upper and lower limit values.

In addition, it is also possible to add a flexible alarm judgment function depending on the object of use.

The storage device 6 is a floppy disk, a magnetic recording medium such as an audio magnetic tape, or an IC card.

A memory card such as an LSI card can be used. It is preferable to use a memory card due to the weight and dimensions of the recording device. Furthermore, in terms of the frequency of replacing the recording medium and environmental resistance, a memory card with a non-contact writing/reading method is preferable to a connector type writing/reading method.

After collecting patrol data, the recording medium is taken out from the storage device 6 and set in a control or management computer in a central monitoring room, control room, etc., and the collected data is stored together with information such as alarms. and then read. At the same time,
Receives and stores newly updated alarm setting values for plant management.

The control device 7 controls the operation of each of the above devices and includes a power supply device and the like.

The appearance of the device will be described with reference to FIG.

The microphone 11 is a helmet-mounted type or a headset type, so that the microphone is always placed near the input speaker's mouth.

The speaker 12 is of a headphone type.

The portable box 13 houses devices other than the audio input device 1 and the audio output device 2.

The present invention utilizes information such as temperature, pressure, flow rate, and liquid level obtained from various types of on-site measuring instruments such as pressure gauges and flow meters.
In order to handle a wide range of subjects, including diagnostic items such as leaks, odors, abnormal noises, corrosion, deformation, and blockages that can be determined using the five human senses,
In addition, in order to reduce the amount of labor required for input by one hour, a voice input method was adopted.

In addition, in order to prevent erroneous inputs due to manual input such as book entry and keystrokes, and to avoid erroneous inputs such as misreading and erroneous recognition by voice recognition devices, after recognizing the input data, it is used for confirmation. Speech synthesis is used to add warning information to the recognized data from the input device and notify the patrol operator.

As a result, compared to other methods, it has become possible to secure safe and reliable data input for a wide range of targets with a light load.

With this device, equipment and equipment in the plant.

In patrol work, which is important for monitoring and managing processes, we were able to reduce the workload of patrollers, prevent input errors, make more effective use of input data, and improve the efficiency of book entry work. In addition, this will allow a small number of patrollers or inexperienced patrollers to patrol more plants, and other expected effects include being able to request more sophisticated work from the patrollers.

FIG. 3 shows a second embodiment.

The main difference from the first embodiment is that by using wireless transmission, the boards that perform important functions in this device can be installed in a central monitoring room with good environmental conditions, making the overall device lighter. It can be realized. This device also enables patrols over a wider area.

The voice input device 21 will be described in detail below. Voice recognition device 22. Audio output device 23. Speech synthesis device 24. Alarm device 25. Storage device 26. Since the control device 27 has the same functions as each device of the first embodiment, here,
A description of this point will be omitted, and only the differences will be described.

This device converts input audio data etc. into wireless signals and transmits them, as well as a patrol aircraft side transmitting/receiving device 28 which is a wireless transmitting/receiving device that receives the transmitted signals and converts them into audio signals etc. It has a transmitting/receiving device 29.

The frequency band and power of the radio waves to be used are based on the regulations of the Radio Law and are based on the regulations of the Radio Law, so as not to affect other devices.

With this device as well, the same effects as in the first embodiment can be obtained, and furthermore, the patroller can use the voice input device 21.
．． Since it is necessary to transport only the audio output device 22 and the transmitting/receiving device 28, the load can be reduced by reducing the weight.

<Effects of the Invention> This device eliminates the need to input ledgers during patrol work, which is important for monitoring and managing equipment and equipment processes in plants, reducing the workload of HTR personnel and making it easier to save data. Erroneous input can be prevented since no key input is required. Additionally, an alarm device allows you to immediately know about an abnormality. Furthermore, since the obtained data is stored in the storage device, it becomes easier to use the data effectively.

In addition, you can check the input data using synthesized sounds.
This allows for more accurate data entry.

Furthermore, since it is a portable device, it can be taken to the site and is easy to work with. At this time, it is more effective to reduce the weight of the equipment by using a wireless transmitter/receiver to carry only the minimum amount of equipment necessary for the site, and to install other equipment in a room with a good environment for the equipment. It is true.

As a result, more plants can be patrolled by a small number of patrollers or even inexperienced patrollers, and other expected effects include requiring patrollers to perform more sophisticated work.
