[0002]

2. Description of the Related Art Conventionally, various systems for detecting work information of a crane and managing a work state based on the detection result have been proposed for the purpose of ensuring the safety of the crane and the like.

[0003] For example, Japanese Patent No. 301112256 discloses that in order to carry out maintenance management related to an engine and a pump, various operation information such as machine operation time, operation frequency, and remaining fuel amount is sent to a management unit through a public line and managed. A system managed by a department is disclosed.

[0004] A system has also been proposed in which information regarding safety is detected in the same manner as described above and sent to a management unit.

[0005]

However, in the conventional management method and system, work management for each crane can be performed, but information for an operator who operates the crane is not included in the information to be sent, and work management for each operator cannot be performed.

For this reason, for example, when performing safety management, an operator who has many dangerous operations or abnormal operations is specified and advice or guidance for improvement is given. It was not possible to perform appropriate work management, such as monitoring the quality of work, or easing the management of good operators with few problems.

Further, when the operator changes cranes, the work history of the operator up to that point is lost, so that the efficiency of work management is low.

Accordingly, the present invention provides a crane work management method and a crane work management method capable of performing work management appropriately and efficiently according to an operator.

[0009]

According to the invention (work management method) of the present invention, the work information of the crane detected by the detection means is taken out of the crane by the transmission means, and recorded together with the identification information of the operator in the data management unit. It is recorded in the means.

According to a second aspect of the present invention, in the method of the first aspect, the identification information of the operator is transmitted from the crane to the data management section together with the work information.

According to a third aspect of the present invention, in the method of the first or second aspect, the work information is written in a storage medium storing the identification information of the operator, and the storage medium is used as transmission means.

According to a fourth aspect of the present invention, in the method according to any one of the first to third aspects, a management network is constructed by connecting a plurality of data management units to a centralized data management unit, and work information is stored in each data management unit and the centralized data management unit. It is managed by the data management unit.

According to a fifth aspect of the present invention, there is provided a work management system.
Is a crane provided with detection means for detecting work information,
A data management unit that manages the work information outside the crane; and a transmission unit that transmits and receives the work information between the crane and the data management unit. The data management unit stores the work information together with the identification information of the operator. A recording means for recording is provided.

According to a sixth aspect of the present invention, in the configuration of the fifth aspect, the crane has a storage unit for storing the detected work information, and the work information stored in the storage unit is transmitted to the transmission unit together with the operator identification information. An information output unit for outputting the information is provided.

According to a seventh aspect of the present invention, in the configuration of the sixth aspect, the crane is provided with a reading section, and the identification information of the operator stored in the storage medium is read by the reading section. .

According to an eighth aspect of the present invention, in the configuration of the fifth aspect, the crane is provided with a writing unit that writes work information to a storage medium storing identification information of the operator and serves as a transmission unit.

According to a ninth aspect of the present invention, in the configuration according to any one of the fifth to eighth aspects, a plurality of data management units are connected to a centralized data management unit via a network, and the centralized data management unit is connected to each of the data management units. Centralized recording means for recording work information with operator identification information to be sent is provided.

According to the above method and system, since the crane work information is managed in the data management section together with the operator identification information, that is, the work information is managed for each operator, an operator who has many dangerous operations or abnormal operations can be promptly operated. It is possible to perform appropriate work management that directly links work information to safety improvement, for example, by making recommendations and guidance for improvement.

Further, since a work history remains for each operator, even if the operator changes cranes, efficient work management can be performed based on the work history of the operator up to that time.

In this case, according to the method of the second and third aspects and the system of the sixth to eighth aspects, since the identification information of the operator is sent together with the operation information from the crane side,
The data management section can easily record and manage this information as work information for each operator as it is.

Further, according to the system of the present invention, since the operator identification information is fetched from the storage medium, there is no occurrence of an input error or insufficient input as in the case of manual input.

On the other hand, according to the method of the third aspect and the system of the eighth aspect, the work information is written into the storage medium storing the operator information to be used as a transmission means, which is taken into the data management unit for management. In the case where there are a plurality of management units, even if the data management unit in charge changes, the work history of the operator can be grasped and managed by the storage medium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings.

First Embodiment (see FIGS. 1 to 3) FIG. 1 shows a schematic configuration of a work management system according to this embodiment.

As shown in FIG. 1, the system includes a crane A and a management center B as a data management unit for managing the crane A.

The crane A has detecting means (not shown).
Processing unit (information output unit according to claim 6) to which various pieces of work information (boom angle, hanging load, operation amount, etc.) detected by the computer are input, and I in which operator identification information is stored.
Reading unit 3 for reading operator identification information from D card 2
And the operation information and the operator identification information
A data storage unit 4 for storing the information via a monitor, and a display unit 5 for displaying the operation information on a monitor for an operator. The information (operation information and operator identification information) stored in the data storage unit 4 is transmitted and received as transmission means. Base station C (8 is its antenna) by unit 6 (7 is its antenna)
Is sent to the management center B via

The ID card 2 may be any medium that stores personal identification information of an operator and can read this information. For example, a so-called IC having an IC chip may be used.
In addition to cards, various cards such as magnetic cards and cards with personal identification numbers can be used.

The management center B has a transmission / reception unit 9, a management-side storage unit 10 as recording means for recording information received by the transmission / reception unit 9, and an operation display unit 11. Then, data processing such as processing the received work information into a format that can be easily viewed by the manager (for example, dividing the information into items such as a boom angle, a hanging load, and a load factor) is performed.

On the other hand, the operation display unit 11 is
The stored contents of 0 are arranged in a predetermined format (for example, the history of the load factor serving as an index of the overload determination is displayed in ascending order within a certain period in the past or in order from the latest).

FIG. 2 shows the flow of information processing on the crane A side.
FIG. 3 shows the flow of information processing in the management center B.

To explain from the crane side, ID card 2
The operator's identification number (so-called ID number) is read from the data (step S1), and various work information sent via the arithmetic processing unit 1 is read (step S2).

The work information includes work states such as a work radius, a load factor, and an actual load, a current operation state, a crane posture, and the like.

Next, in step S3, the fetched work information is stored in chronological order. The period at which the work information is stored may be the period at which the work information is transmitted, or may be longer than the period at which the time series change can be determined.

Further, the capacity of the data storage unit 4 is limited, and when it is necessary to store data exceeding a set limit value, old data is deleted in time series and updated to new data.

Subsequently, based on the latest information, a preset reference (for example, a boom angle of 89 ° or more and a load factor of 99
% Or more, which may cause the crane to fall or break)
It is determined whether or not the crane is in a dangerous state based on the information (step S4). When YES (danger) is determined, the stored work information and operator identification information are sent to the management center B by the transmission / reception unit 6. Send (Step S
5).

The transmission and reception between the crane A and the base station C may use a public communication network such as a satellite communication network, a portable telephone network, a PHS network, or a dedicated communication network. When a mobile phone network is used, a mobile phone owned by an operator can be used as a transmitting / receiving means.

Alternatively, a general-purpose wireless or portable terminal may be used as the transmission means. This applies to the transmission and reception between the base station C and the management center B.

In the management center B, step S1 in FIG.
Then, the information sent from the crane A side is received, and this information is taken into the management side storage unit 10 and stored.

Further, in step S3, the data is processed on the calculation display section 11 such that the data is processed so as to be easily viewed by the administrator, and then displayed on a monitor, and if necessary, recorded and printed out. At this time, an audible alarm may be issued to notify the manager of the dangerous state.

In the figure, information on only one crane is sent to the management center B. However, information on a plurality of cranes is usually sent to the management center B and centrally managed.

In this way, since the operation information of the crane A can be managed for each operator, the operator who has many dangerous operations or abnormal operations can be quickly identified, and advice or guidance for improvement can be given, and the operation information can be improved for safety. Appropriate work management that is directly connected to such as becomes possible.

Further, since the work history remains for each operator, even if the operator changes cranes, continuous work management can be performed by adding new work information to the work history so far.

Moreover, since the identification information of the operator is sent together with the work information from the crane, the management center B can easily manage this information as it is as the work information for each operator.

In addition, since the operator identification information (ID number) is fetched from the ID card 2, there is no occurrence of an input error or insufficient input as in the case of manual input.

Second Embodiment (see FIGS. 4 to 6) Only differences from the first embodiment will be described.

In the second embodiment, the transmission / reception units 6, 9 of the first embodiment (FIG. 1) are omitted in the crane A and the management center B as shown in FIG. The writing unit 12 and the reading unit 13 provided in the management center B are provided.

The writing section 12 of the crane A writes the work information sent through the arithmetic processing section 1 into the ID card 14.
(In addition to storing the operator identification information, the information is newly written on a writable storage medium (for example, an IC card).

That is, as shown in FIG. 5, after fetching the ID number (step S1) and fetching the work information from the arithmetic processing unit 1 (step S2), the information is stored in the data storage unit 4 in chronological order. (Step S3), when a dangerous state is determined (YES in Step S4)
Then, the stored work information with the operator identification information is written into the ID card 14 (step S5).

The ID card 14 is brought to the management center B as a transmission means (a so-called data card), and is read by the reading unit 13 of the center B.
(Operation information and operator identification information) are read and stored in the management-side storage unit 10 and displayed on the calculation display unit 11.

That is, as shown in FIG.
In step S1, information from the ID card 14 is read, and the read information is stored in the management storage unit 10 in step S2. Next, in step S3, the data is processed on the calculation display unit 11 such that the data is processed so that the administrator can easily see it, and then displayed on a monitor, and printed out as necessary (step S3).

As described above, in the first embodiment, information is transmitted and received, whereas in the second embodiment, information is transmitted to the management center B via the ID card 14 which is a portable storage medium. I am taking.

In this way, for example, when there are a plurality of management centers B for each site, even if the management center B in charge changes, the work history of the operator is grasped and managed by the new management center B by the ID card 14. be able to.

Further, since the ID card 14 is a portable transmission means (data card), expensive transmission means such as wireless communication equipment is not required, and the equipment cost and running cost can be reduced.

Other Embodiments (1) Combining the first embodiment and the second embodiment, the work information is transmitted from the crane A to the management center B together with the operator identification information read from the ID card, and the work information is transmitted to the ID card. The information may be written into a data card, and the management center B may be configured to take in the stored contents of the card at any time.

In this way, the degree of freedom in information transmission can be further increased.

(2) As another embodiment, only the work information is sent from the crane A to the management center B in the first embodiment, and only the work information of the crane A is written on the data card in the second embodiment, and the ID information is written. May be added by the management center B using an ID card or by manual input.

This eliminates the risk of the operator losing the ID card or forgetting to attach ID information in the first embodiment.

(3) In the above embodiment, the crane work information is managed by only one management center B. However, as shown in FIG.
Are connected to a centralized management center (centralized data management unit) D via a communication network (or a portable storage medium) to form a management network, and information on a large number of cranes is stored in each management center B1, B2, B3. , And may be managed collectively by the central management center D.

Reference numeral 15 denotes a centralized recording unit for recording information from each of the management centers B in the centralized management center D.
In FIG. 7, each management center B1, B2, B3
The branch codes 1, 2, and 3 are assigned to the crane A and the base station C, respectively, and the branch codes a are assigned to the antennas 7 and 8, respectively.

With such a configuration, for example, the management center B1, B2, B3,... For each of the construction sites and the construction companies, the recorded information of the central management center D is stored in the crane industry (the crane leasing industry, the crane manufacturing industry, etc.). , Crane construction industry) as a common database in a wide range, such as for the employment and training of operators,
It can be used effectively.

(4) As the operator identification information, the mobile phone number of the operator may be used instead of the ID card information.

As another means for identifying an operator, there is a personal authentication system and apparatus for identifying whether or not the operator is himself or herself based on operator identification information (fingerprint, retina, voiceprint identification, etc.) recorded in advance. Yes, these may be used as operator identification means. By using such a feature such as a part of the body of an individual as identification means for the operator, it is possible to more reliably identify whether or not the user is the individual.

Further, the operator identification information is sent to the management center, for example, when the engine is started or when the safety lifting / lowering shut-off lever provided at the lifting / lowering opening of the crane cab is turned on or off. May be recorded and transmitted to the management center every predetermined time or every predetermined amount of data.

In this case, the operator's personal identification information (for example, voiceprint) is registered in the management center in advance, the identification information read and transmitted by the reading means on the crane side is collated with the registration information, and the collation result is obtained. A system may be used in which the control center transmits the signal to the crane, and the transmission signal is used as a key so that the engine can be started.

With the configuration in which the operator is identified on the management center side as described above, the possibility of erroneous identification due to counterfeiting, falsification, etc. of the ID card is higher than in the case where the operator is identified on the crane side using an ID card or the like. The safety management is more reliable, and there is no possibility that the work becomes impossible due to the card damage.

The identification information may be unique to each operator, or the signal of the collation result transmitted from the management center to the crane as a starting signal may be a random signal. In this case, there is no possibility that the safety device is illegally released by an incorrect start signal.

Further, if the identification information is collectively managed by the network system shown in FIG. 7, it is possible to confirm whether the same identification information is used repeatedly and at the same time, so that the ID card is forged or altered. In addition, illegal use of the crane can be confirmed, and safety management can be more thoroughly performed.

[0070]

As described above, according to the present invention, the work information of the crane is managed in the data management unit (for each operator) together with the identification information of the operator, so that the operator who has many dangerous operations and abnormal operations can be quickly identified. Thus, it is possible to perform appropriate work management that directly links work information to safety improvement, such as making recommendations and guidance for improvement.

Further, since the work history remains for each operator, even if the operator changes cranes, efficient work management can be performed based on the work history of the operator up to that time.

In this case, according to the method of claims 2 and 3 and the inventions of claims 6 to 8, since the identification information of the operator is sent from the crane together with the work information, the data management section keeps this information as it is. It can be easily recorded and managed as work information for each operator.

Further, according to the invention of claim 7, since the operator identification information is taken in from the ID card, there is no occurrence of an input error or insufficient input as in the case of manual input.

On the other hand, according to the third and eighth aspects of the present invention, the work information is written into an ID card unique to the operator to be used as a data card, which is brought into the data management section for management. Even if the data management unit under the jurisdiction changes, the work history of the operator can be grasped and managed by the data card.

Further, since the data card is a portable transmission means, expensive transmission means such as wireless communication equipment is not required, and equipment cost and running cost can be reduced.

According to the fourth and ninth aspects of the present invention, when there are a plurality of data management units, while the work information for each operator is separately managed by each data management unit, the network management is simultaneously performed by the centralized data management unit. Therefore, it can be effectively used as a common database in a wide range such as the entire crane industry.
