FIG. 1 is a configuration diagram showing an outline of a management system according to an embodiment of the present invention. The management system A according to the present invention has the following configuration. That is, the general management center 1 can communicate with each of the crane bases 21, 22, and 23 via the network N1. The general management center 1 can communicate with a user PC (Personal Computer) 3 via a network N2, and can communicate with a research and development center 4 via a network N3. The service center 5 can communicate with the user PC 3 via the network N2. Further, the service center 5 can communicate with the overall management center 1 and the research and development center 4 via the network N3.
The management system A is a cloud computing system that can use a service provided by a group of servers existing on a network without being aware of the group of servers.
The overall management center 1 collectively manages operation information and alarm information received from the crane bases 21, 22, and 23, equipment information of each crane input from the user PC 3 in advance. Further, the overall management center 1 provides various information regarding a specific crane base to the user PC 3 via the network N2 based on the above-described information.
Details of the overall management center 1 will be described later.

The crane base 21 has cranes 211a and 211b, interfaces 212a and 212b, control devices 213a and 213b, and communication means 214.
The crane 211a is, for example, a well-known crane used in a garbage disposal site or the like, and has the following configuration. That is, the traveling device (not shown) moves the girder (not shown) on the first rail (not shown). Further, a traversing device (not shown) moves a trolley (not shown) as a carriage on a second rail (not shown) provided on the girder. Further, a bucket (not shown) provided with a claw body (not shown) is suspended from the trolley. As described above, the control device 213a controls the traveling device and the traversing device, so that the crane 211a can be moved to any place in the waste disposal site.

Further, the hoisting device (not shown) is configured to move the bucket up and down by performing a hoisting operation or a lowering operation of a wire rope (not shown) for suspending the bucket.
Each control described above is realized by the control device 213a controlling an inverter (not shown) corresponding to each device described above. In addition, the hoisting device (not shown), the traversing device (not shown), and the traveling device (not shown) are each provided with a brake (not shown) that stops its movement in accordance with a command from the control device 213a. Yes.

In addition, the control device 213a receives command values for controlling a hoisting device (not shown), a traversing device (not shown), a traveling device (not shown), etc. via the interface 212a. Output to. In addition, the control device 213a uses a sensor corresponding to each measurement (eg, information on the position, speed, acceleration of the hoisting device, the traversing device, the traveling device, information on the load of the object (garbage) lifted by the crane 211a, etc.) (Not shown) every predetermined time.
Further, the crane 211a is provided with a plurality of interlocks (not shown), and the control device 213a acquires alarm information from the interlocks and the time when the alarm is issued. And the control apparatus 213a becomes a structure which can output said command value information, measurement information, such as the position of the crane 211a, alarm information, etc. to the integrated management center 1 via the communication means 214 and the network N1. Yes.

The crane 211b is also present in the crane base 21 where the crane 211a is installed (located in the facility near the crane 211a). It is assumed that at least one crane is installed in the “crane base” in the base (area).
Note that the configurations of the crane 211b, the interface 212b, and the control device 213b are the same as described above, and thus description thereof is omitted.
The control device 213a for controlling the crane 211a and the control device 213b for controlling the crane 211b are connected to the command means, measurement information such as the crane position, alarm information, etc. via the communication means 214 and the network N1. Is transmitted to the overall management center 1. Incidentally, the information transmitted from the control device 213a and the information transmitted from the control device 213b may be transmitted to the overall management center 1 through different communication means.

The crane base 22 exists in an area different from the above-described crane base 21 and includes a crane 221, an interface 222, a control device 223, and a communication unit 224. Since each of these components is the same as that described above, the description thereof is omitted. The same applies to each component of the crane base 23.
In addition, in FIG. 1 (and FIG. 2), although the case where one or two cranes are installed in one crane base is shown, the number of cranes installed in one clay base is not limited to this, Three or more units may be used. Moreover, although FIG. 1 (and FIG. 2) shows the case where there are three crane bases, the present invention is not limited to this, and at least one crane base is sufficient, and the number of bases is not limited.
Hereinafter, when referring to an arbitrary crane base, crane, control device, communication means, etc., it will be simply referred to as “crane base” or the like without reference numerals.

Further, the information transmitted from the communication means 214, 224, 234 at each crane site is encrypted and transmitted to the central management center 1 via the network N1. Then, the communication means 101 (see FIG. 2) provided in the overall management center 1 decrypts each encrypted information received from each of the communication means 214, 224, 234, and information obtained from which communication means It is the structure which can identify whether it is.
Therefore, the network N1 and each communication means are constructed so that, for example, an administrator of a specific crane base cannot obtain information on a crane base that he / she has not registered, as well as an outsider.

For example, the user PC 3 is installed in a central operation room (not shown) of each of the crane bases 21, 22, and 23, and can communicate with the overall management center 1 via the network N2. Here, the “user” is assumed to be a person who manages information regarding each crane base (for example, the crane base 21). Moreover, in order to refer to the information regarding a crane as a "user", the person who contracted beforehand with the administrator of the specific crane base etc. is assumed.
In FIG. 1 (and FIG. 2), only one user PC 3 is depicted, but in reality, a personal computer installed in a central operation room (not shown) at each crane base, or a wireless device described later. There are a plurality of computers such as personal computers that users use in places other than the central control room using communication cards.

For example, the user PC 3 is installed in a central operation room in a specific crane base, and is connected to the Internet line via the network N2. Then, by inputting the user ID and password and being authenticated by the authentication server 113 (see FIG. 2), the user can view the information transmitted from the central management center 1.
Further, as described above, the user can browse information from the general management center 1 in the central operation room (not shown) of the crane base, and also connect a wireless communication card to the user PC 3 outside the central operation room. Through the authentication process by the authentication server 113 (see FIG. 2), information from the overall management center 1 can be browsed.
By the way, by the authentication by the authentication server 113 (see FIG. 2) provided in the overall management center 1, the user can browse only the information on each crane installed at the crane base that he / she has registered, Information on crane sites that are not available cannot be viewed. This is to prevent information on a specific crane base from leaking to outsiders.

  The user can share information in real time with the service staff of the service center 3 in the event that the crane at the crane base that he / she has registered for, for example, and the correspondence with the service staff described above. You can contact us by email or telephone (details will be given later).

In the research and development center 4, by acquiring information stored in each storage means 104 to 108 (see FIG. 2) of the overall management center 1, and analyzing the information, a more advanced management system is researched and developed. . The research and development center 4 updates and upgrades various applications used in the overall management center 1 via the communication means 41 and the network N3.
The research and development center 4 includes a communication unit 41, a storage unit 42, a control unit 43, an information analysis unit 44, and a dedicated PC 45. The communication means 41 enables communication between the general management center 1 and the research and development center 4 via the network N3. The storage means 42 stores various data acquired from the overall management center 1. The control means 43 stores the various data acquired from the overall management center 1 via the network N3 and the communication means 41 in the storage means 42 and controls the entire system of the research and development center 4.
The information analysis unit 44 performs information analysis using the information stored in the storage unit 42 and outputs the result to the dedicated PC 45. The dedicated PC 45 displays the information analysis result on a monitor (not shown) so that the developer can confirm the result. The dedicated PC 45 can perform various settings when the information analysis unit 44 performs information analysis via an input unit (not shown).
Information acquired by the research and development center 4 from the overall management center 1 will be described later.

The service center 5 can acquire various pieces of information stored in the storage units 104 to 108 (see FIG. 2) of the overall management center 1 via the network N3, and is useful for the user based on the information. prepare documents. In addition, the service staff of the service center 5 can contact the user by e-mail or telephone regarding a registered crane failure or the like.
The service center 5 has a service PC 51 and a management PC 52.
In the service PC 51, for example, when a service person inputs a user's ID via an input means (not shown), a screen (for example, FIG. 5) displayed on the user's user PC 3 (see FIG. 1). You can see a screen similar to the operating status screen.
A service person who operates the service PC 51 can quickly respond by contacting the user using an e-mail or a telephone while browsing the above screen when a crane failure occurs. Is possible.

The management PC 52 is configured to be able to acquire information stored in each storage unit 104 to 108 of the overall management center 1 via the network N3 and the communication unit 118 (see FIG. 2). The management PC 52 is installed in a management room of the service center 5 or the like. The administrator of the service center 5 constantly monitors information regarding each crane displayed on the monitor (not shown) of the management PC 52. For example, when a crane breaks down, alarm information corresponding to the broken point is immediately transmitted to the management PC 52 of the service center 5 via the network N3.
Although details will be described later, when warning information having predetermined contents (or a predetermined level or more) set in advance is transmitted from the crane control device to the first information acquisition unit 102a, the bus 111 and the communication means The alarm information is directly transmitted to the management PC 52 of the service center 5 via 118.
In other words, when an alarm having a predetermined content (or a predetermined level or higher) is issued in an arbitrary crane control device at each crane base, the manager watching the management PC 52 of the service center 5 The presence or absence of the alarm and its contents can be grasped at almost the same timing as the worker.

  FIG. 2 is a configuration diagram of the management system, showing a detailed configuration of the overall management center. As shown in FIG. 2, the overall management center 1 includes a communication unit 101, a first information management unit 102, an F / W (firewall) 103, various storage units 104 to 108, and an information analysis unit. 109, a bus 111, a communication unit 112, an authentication server 113, F / Ws 114a and 114b, a front server 115, a second information management unit 116, an F / W 117, and a communication unit 118. ing.

As described above, the communication unit 101 decrypts the encrypted information received from the communication units 214, 224, and 234 (see FIG. 1) installed at the crane bases 21, 22, and 23, respectively. In this configuration, it is possible to identify from which communication means the received information is transmitted.
The 1st information management means 102 acquires monitoring information from the control apparatus of each crane. In addition, the first information management unit 102 discloses monitoring information related to a crane installed at the crane base to users belonging to the specific crane base.
Here, the “monitoring information” refers to information including crane operation information, alarm information, and diagnostic information.

The first information management unit 102 includes a first information acquisition unit 102a and a first information disclosure unit 102b.
The first information acquisition unit 102a acquires operation information and alarm information from the control device of each crane via the network N1, the communication unit 101, and the F / W 114a, and the operation information storage unit 104 and alarm / diagnosis information storage unit Each is stored in 105.
Here, the operation information is, for example, the position information and speed information related to the hoisting device, the traversing device, and the traveling device, the information related to the load of the lifted object (garbage), and the information related to the command value of each control device. is there. In addition, the operation information includes predetermined state information (ON / OFF information) related to the operation of each device constituting the crane. For example, the control device corresponds to each state of the crane shown in FIG. 5 and, if applicable, information to that effect (for example, if the hoisting inverter output is “forward rotation”, information corresponding thereto) : See FIG. 5) to the first information acquisition unit 102a.

The alarm information includes alarm information, alarm level, and time information indicating the time when the alarm is uttered, which is input from an interlock installed at a plurality of locations of the crane. For example, when the main power supply current of the crane 211a (see FIG. 1) is over, a not-shown wiring breaker (Molded Case Circuit Breaker: MCB) is released, and a signal to that effect is input to the control device 213a. Is done. That is, as described above, when a certain alarm is generated, the control device 213 sets a flag corresponding to the alarm content, and also associates with the time information when the alarm is generated as a storage unit (not shown) as alarm information. To store. When the control device 213a (see FIG. 1) receives the operation information transmission command signal from the communication program (not shown) of the first information acquisition unit 102a (see FIG. 2), The alarm information stored in the storage unit is read and transmitted to the first information acquisition unit.
Note that a communication program (not shown) incorporated in the first information acquisition unit 102a sends the above command to each control device via the communication unit 101 and the network N1 every predetermined time (for example, 0.1 sec). A signal is transmitted.

  The diagnostic information includes failure cause information corresponding to the alarm information and instruction information for recovering the crane from the failure state. For example, as shown in the first row of the alarm message G405 and diagnostic message G411 on the alarm list screen shown in FIG. 7, the alarm information indicating “travel braking abnormality” (see G405) includes “travel discharge unit abnormality detected. "The brake unit is faulty or the frequency of starting and stopping is too high" (see G411). Although details will be described later, the diagnostic information is stored in advance in the alarm / diagnosis information storage unit 105 in correspondence with each alarm information.

The first information disclosure unit 102b has received a command signal to acquire crane monitoring information (operation information, alarm information, and diagnostic information) from the user PC 3 of the user whose validity has been confirmed by the authentication server 113. In this case, according to the command signal, monitoring information corresponding to the command signal is read from each of the storage units 104 to 107, and the monitoring information is transmitted as screen information to the user PC 3 via the communication unit 112 and the network N2.
Incidentally, the information stored in the device information storage means 108 is managed by the second information management means 116.

For example, when receiving the operation information acquisition command signal from the user PC 3, the first information disclosure unit 102 b reads the crane site operation information corresponding to the user ID from the operation information storage unit 104, and sends it to the front server 115. Output. In this case, the first information disclosure unit 102b does not acquire all the operation information of the crane base corresponding to the user ID from the operation information storage unit 104, but a part necessary for displaying the screen on the user PC 3. (For example, information required when presenting the operation status screen G3 shown in FIG. 5) is selectively acquired. Further, the first information disclosure unit 102b also performs control for converting the selectively acquired information into information that can be displayed on a monitor (not shown) of the user PC 3.
The above-described processing by the first information disclosure unit 102b is the same when acquiring predetermined information from the other storage units 105 to 107.

The F / W (Firewall) 103 fulfills a security function for preventing data stored in the storage units 104 to 108 of the central management center 1 from being illegally acquired by a third party.
In the operation information storage unit 104, the information on the command values by each control device, the measurement information such as the crane position, and the time information at which each information is acquired correspond to each crane in a database format. Are stored in different storage areas. Incidentally, the operation information transmitted from the control device of each crane base to the general management center 1 is attached with identification information corresponding to each device constituting the crane. The device information storage means 108 stores in advance the device name, device code, model, etc. of each device constituting the crane in association with the above identification information (details of the device information will be described later). .

In the alarm / diagnosis information storage unit 105, the alarm information from the control device described above and the time when the alarm information was acquired are stored in different storage areas corresponding to each crane in the form of a database. Has been. In the alarm / diagnosis information storage unit 105, diagnosis information corresponding to the alarm information is stored in advance. The diagnostic information is stored in advance in the alarm / diagnosis information storage unit 105 from the research and development center 4 (or the user PC 3) based on the information about the equipment constituting each crane.
Incidentally, as the alarm information, the above-described predetermined state information (ON / OFF information) relating to the operation of each of the devices constituting the crane may be stored in the alarm / diagnosis information storage unit 105 in further correspondence. Good.
Further, the alarm / diagnosis information storage unit 105 stores information related to the correspondence between the alarm information and the diagnosis information. Incidentally, alarm information and diagnostic information are not necessarily in a one-to-one correspondence, and a predetermined combination of alarm information and specific diagnostic information may be associated with each other.

The operating time / number of times information storage means 106 stores the operating time and the number of times of operation of the hoisting device (not shown), the traversing device (not shown), the traveling device (not shown), etc. Correspondingly, they are stored in different storage areas. For example, the operation time / number of times information storage means 106 stores each crane operation time and each operation count in the morning (9:00 to 12:00), noon (13: 0 to 17:00), and night (17: A total value in each time zone (00 to 21:00), a total value per day, an average value per hour, and the like are stored in a database format (see FIG. 9).
Incidentally, with respect to the above-described operation time and number of operations, the operation information stored in the operation information storage unit 104 is read and calculated by the information analysis unit 109 described later, and stored in the operation information / count information storage unit 106.

The operation information storage means 107 stores the equipment code, equipment name, model, number of operations, number of times of service, the number of times of previous replacement, etc. in a database format corresponding to each equipment constituting each crane (see FIG. 10). ).
By the way, regarding the above-mentioned device code, device name, model, number of times of service, and previous replacement date, the administrator of each crane base sends each information from the user PC 3 to the general management center 1 when registering with the general management center 1. Send data. Then, the second information acquisition unit 116a stores the information received via the communication unit 112 in the operation information storage unit 107 in association with each crane. In addition, when a user newly replaces each crane device, the user transmits the replacement date to the general management center 1. Then, the second information acquisition unit 116a updates the above “previous exchange date”. The first information acquisition unit 102a may have the update function described above.
Details of the second information acquisition unit 116a will be described later.

In the equipment information storage means 108, as shown in FIG. 12, the crane base name and base code (see FIG. 12 (a)) of each crane base, the crane name and crane code of each crane (see FIG. 12 (b)). ) Is stored in database format.
Further, in the device information storage means 108, as shown in FIG. 13, the device name, device code, model, operation count, life count, alarm history, previous inspection date, inspection result, previous replacement date, next replacement date, The stock quantity and the like are stored in different storage areas corresponding to each crane in a database format.
Incidentally, with respect to the device name, device code, type, number of times of life, and number of stock, each data is transmitted from the user PC 3 to the general management center 1 in advance, and the second information acquisition unit 116a receives each crane. And stored in the device information storage means 108.
In addition, the number of operations shown in FIG. 13 is calculated by reading the operation information stored in the operation information storage unit 104 by the information analysis unit 109, calculating the number of operations based on the operation information, and device information storage unit every predetermined time. The data is stored in 108 and updated. Further, the alarm history shown in FIG. 13 is updated by the information analysis means 109 reading the alarm information stored in the alarm / diagnosis information storage means 105 and storing it in the device information storage means 108 every predetermined time.

Further, regarding the previous inspection date and the inspection result shown in FIG. 13, the workers working at each crane base inspect the state of each device every predetermined period, and the inspection record is sent from the user PC 3 to the general management center 1. The second information acquisition unit 116a acquires the information and stores it in the device information storage unit 108. Incidentally, in the above inspection, for example, an operator at a crane site can inspect each device using a mobile terminal (not shown) and transfer the inspection information to the control device at the crane site.
In addition, the previous replacement date shown in FIG. 13 is the same as the above, and when the crane equipment is newly replaced, the crane base operator uses the mobile terminal (not shown) to replace the equipment. And the exchange date is transmitted to the general management center 1. Then, the second information acquisition unit 116a updates the “previous replacement date” and the “stock quantity”.
By the way, as for the inventory quantity of equipment at the time of registration, the user of each crane base sends the inventory quantity of each equipment constituting the crane to the general management center 1 at the time of registration of the service, and the second information acquisition unit 116a Information on the number of stocks is stored in the device information storage means 108 for each device.

Further, the next scheduled replacement date shown in FIG. 13 is calculated by the information analysis unit 109 based on the number of operations, the number of lifetimes of each device, the scheduled previous replacement date, the average number of operations per day, and the like. In addition, the information analysis means 109 may determine the next scheduled replacement date in consideration of the alarm history and inspection details. For example, when a serious failure alarm is recorded as an alarm history for a specific device, the number of lifetimes may be set to be reduced by a predetermined number corresponding to the alarm content.
The method for determining the next scheduled replacement date by the information analysis means 109 can be newly updated by the research and development center 4.

The information analysis unit 109 includes an electronic circuit (not shown) such as a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and various interfaces. The information analysis unit 109 performs various processes shown below based on the set program.
For example, the information analysis unit 109 calculates the operation time / number of times information based on the operation information stored in the operation information storage unit 104 and stores it in the operation time / number of times information storage unit 106 (see FIG. 9). Further, the information analysis unit 109 calculates the number of operations of each device constituting the crane based on the operation information stored in the operation information storage unit 104 and stores it in the operation information storage unit 107 and the device information storage unit 108. (See FIGS. 10 and 13). The information analyzing unit 109 calculates the next replacement scheduled date of each device constituting the crane based on the device information stored in the device storage unit 108 (see FIG. 13).

The bus 111 is connected to the first information management unit 102, the second information management unit 116, the storage units 104 to 108, the information analysis unit 109, and the communication unit 118, and is described above. Exchange of information is possible.
The communication unit 112 is a communication line that connects the user PC 3 and the authentication server 113 via the network N2. The communication unit 112 can transmit / receive information to / from the front server 115 via the communication line corresponding to the user ID and the F / W 114b after the authenticity of the user is confirmed by the authentication server 113. .

The authentication server 113 verifies the validity of the user by authenticating the user ID, which is unique information regarding the user identifier, and the password corresponding to the user ID. That is, the authentication server 113 performs an authentication process using a public key and a secret key that are publicly known.
The F / Ws 114a and 114b have a security function for preventing a third party from entering the integrated management center 1 from the outside and acquiring data illegally.
When the authentication process by the authentication server 113 is completed, the front server 115 outputs the user ID to the first information disclosure unit 102b and the second information disclosure unit 116b. Incidentally, the user ID is associated with one or a plurality of crane bases at the time of registration. Further, the front server 115 uses an input means (not shown) such as a mouse for a user who sees a screen displayed on a monitor (not shown) of the user PC 3 to use a predetermined selection button displayed on the screen. The selection information is output to the first information disclosing unit 102b or the second information disclosing unit 116b.
Details of the screen example displayed on the user PC 3 and the selection information will be described later.

The second information management unit 116 acquires device information from the user PC 3. In addition, the second information management unit 116 makes the device information related to the crane installed at the crane base public to the user belonging to the specific crane base.
The second information management unit 116 includes a second information acquisition unit 116a and a second information disclosure unit 116b.
The second information acquisition unit 116a acquires device information from the user PC 3 via the network N2 and the communication unit 112, and stores the device information in the operation information storage unit 107 and the device information storage unit 108 for each crane. The device information includes, for example, each device code, device name, model, number of devices in stock, number of lifetimes, detailed specifications and circuit configuration of each device, information on images, and the like. The device information also includes the next replacement scheduled date for each device, which is determined by the information analysis unit 109 based on the above information.
Incidentally, the user PC 3 that transmits the equipment information of each crane existing at a specific crane base to the central management center 1 is the same as the PC 3 that acquires and displays the above-mentioned crane base monitoring information from the central management center 1. This is not always the case and may be different.

When the second information disclosure unit 116b receives a command signal for acquiring device information about the device constituting the crane from the user PC3 of the user whose validity is authenticated by the authentication server 113, the second information disclosure unit 116b, according to the command signal, The device information is read from the device information storage means 108, and the device information is transmitted as screen information to the user PC 3 via the communication means 112.
For example, when receiving the device information acquisition command signal from the user PC 3, the second information disclosure unit 116 b reads the device information of the crane base corresponding to the user ID from the device information storage unit 108, and sends it to the front server 115. Output.

In this case, the second information disclosure unit 116b does not acquire all of the equipment information of the crane base corresponding to the user ID from the equipment information storage unit 108, but a part necessary for displaying the screen on the user PC 3. (For example, information necessary when presenting the maintenance management service display screen G7 shown in FIG. 13) is selectively acquired from the device information storage means 108.
Furthermore, the second information disclosure unit 116b also performs control for converting the selectively acquired information into information that can be displayed on a monitor (not shown) of the user PC 3.
Incidentally, each of the first information management means 102 and the second information management means 116 may be composed of one server, or one server is divided into a plurality of virtual computers, Each OS (Operating System) and application software corresponding to the above functions may be operated.
Further, each of the first information management means 102 and the second information management means 116 is made up of a plurality of servers to make them redundant, and when an abnormality occurs in a specific server, the above function is quickly transferred to another server. The management system A may be stabilized.

The F / W 117 has a security function for preventing a third party from entering the central management center 1 from the outside and acquiring data illegally.
The communication unit 118 is a communication line for communicating with the communication unit 41 (see FIG. 1) of the research and development center 4 via the network N3. As described above, the user can browse only the information acquired from the storage means 104 to 108 by the first information disclosure unit 102b or the second information disclosure unit 116b among the information regarding the crane base to which the user belongs. It is.
In contrast, the dedicated PC 45 (see FIG. 1) of the R & D center 4 directly receives information from the central management center 1 without performing selection processing by the first information disclosure unit 102b or the second information disclosure unit 116b. It can be acquired automatically. That is, the research and development center 4 can browse the information stored in the storage means 104 to 108 of the overall management center 1 as it is and use it for research and development, upgrade of the management system A, and the like.

<Processing process and screen display example of equipment monitoring service>
In the following description, as an example, a case will be described in which monitoring information (crane operation information, alarm information, and diagnostic information) is acquired or disclosed from the crane base 21 (see FIG. 1).

(1. Operation status)
FIG. 3 is a sequence showing an operation description related to the operation information acquisition process.
In step S101 of FIG. 3, the communication program (not shown) of the first information acquisition unit 102a (see FIG. 2) is transmitted to the control device 213a via the communication means 101, the network N1, and the communication means 214 (see FIG. 1). , 213b (see FIG. 1), an operation information transmission command signal is transmitted.

The alarm information transmission command signal is transmitted to. In step S202, when the control devices 213a and 213b receive the alarm information transmission command signal, the control devices 213a and 213b transmit corresponding alarm information to the first information acquisition unit 102a. In step S203, the first information acquisition unit 102a transmits the alarm information to the information analysis unit 109.

In step S204, the information analysis unit 109 searches the alarm / diagnosis information storage unit 105 for diagnostic information corresponding to the alarm information, and acquires the diagnostic information (step S205). In step S206, the information analysis unit 109 associates the alarm information with the diagnostic information and transmits them to the management PC 52 (see FIG. 1). As a result, the administrator of the service center 5 (see FIG. 1) can know the alarm information and the diagnostic information at almost the same timing as when the alarm is generated at the site where the crane is installed. Then, the service staff of the service center 5 can contact the user of the crane base where the alarm has occurred immediately using e-mail or telephone.
Incidentally, in the process of step S206, it is preferable to transmit alarm / diagnosis information to the management PC 52 only in the case of alarm information having a predetermined content (or a predetermined level or higher).
Note that the processes in steps S201 to S206 are repeatedly executed every predetermined time (for example, 0.1 sec).

  In step S207, the PC 3 transmits the user ID and password to the authentication server 113 via the network N2, and in step S208, the authentication server 113 performs authentication processing. After the authentication process is completed, when the user wants to browse the crane alarm list screen, the user selects “alarm list” G12 shown in FIG. By this operation, the user PC 3 transmits a warning / diagnosis information acquisition command signal to the first information disclosure unit 102b in step S209 of FIG. In step S210, the first information disclosure unit 102b searches the alarm / diagnosis information storage unit 105 for the alarm / diagnosis information at the crane base corresponding to the user ID, and acquires the alarm diagnosis information (step S211). In step S212, the first information disclosure unit 102b transmits alarm / diagnosis information to the user PC 3.

Then, the alarm list display screen G4 shown in FIG. 7 is displayed on the monitor (not shown) of the user PC 3. In FIG. 7, the display is described in two stages. However, when the display is performed on the user PC 3, it is displayed as one stage and can be scrolled left and right by a scroll bar (not shown).
The alarm list screen G4 displays alarm / diagnosis information up to the time when the user accesses the site of the crane remote monitoring service (or the month specified by the user). In the alarm list screen G4, as shown in FIG. 7, for example, an alarm “occurrence time” G401, a failure “recovery time” G402, a failure location “state” G403, an “alarm level” G404, an “alarm message” G405, “winding position” G406, “traveling position” G407, “transverse position” G408, whether the bucket (not shown) described above is “open state” G409 or “closed state” G410 A diagnostic message 411 or the like is displayed. By the way, the “winding position” G406, “traveling position” G407, and “transverse position” G408 of the alarm list display screen G4 refer to the time when the alarm is generated and the user ID, and the first information acquisition unit 102a is activated. The information can be displayed by acquiring the operation information of the corresponding crane from the information storage unit 104.

(3. Operation management table)
FIG. 8 is a sequence showing an operation description related to the operation time / times information acquisition processing.
In step S301 of FIG. 8, the information analysis unit 109 searches the operation information for each crane and acquires the operation information (step S302). For example, as shown in FIG. 9, when calculating the operation time and the number of operations in the time zone of “morning, daytime, and nighttime” G503, the search processing by the information analysis unit 109 is performed per day. It is enough to go three times at a fixed time.
In step S303, the information analysis unit 109 calculates the operation time and the number of operations based on the acquired operation information. For example, as shown in FIG. 9, the information analysis means 109 performs the hoisting operation time and hoisting operation of the crane hoisting device (not shown) in the time zone of “morning, daytime, night” G503. Calculate the number of times. Further, the information analysis unit 109 calculates a “total” G504 of each operation time and the number of operations per day and an “average” G505 per hour.
In step S <b> 304, the information analysis unit 109 stores the operation time / number of times information in the operation time / number of times information storage unit 106.
Note that the processing of steps S301 to S304 is executed by the information analysis means 109 a predetermined number of times per day corresponding to the time zone of G503 shown in FIG. 9 described above, and the processing is continued every day.

In step S305 in FIG. 8, the PC 3 transmits the user ID and password to the authentication server 113 via the network N2, and the authentication server 113 performs authentication processing in step S306.
After the authentication process is completed, when the user wants to browse the crane operation management table screen, the user selects “operation management table” G13 shown in FIG. By this operation, in step S307 in FIG. 6, the user PC 3 transmits an operation time / times information acquisition command signal to the first information disclosure unit 102b. In step S308, the first information disclosure unit 102b searches the operation time / number information at the crane base corresponding to the user ID from the operation time / number information storage unit 106, and acquires the operation time / number information (step S308). S309). Further, in step S310, the first information disclosure unit 102b transmits the operation time / number of times information to the user PC 3.

Then, an operation management table screen G5 shown in FIG. 9 is displayed on the user PC 3. On the operation management table screen G5, a “classification” G501 for distinguishing between “main circuit” G501a and “manual / automatic” G501b of the crane is displayed. Incidentally, “manual” indicates a case where the operator manually moves the crane. On the other hand, “automatic” indicates a case where the crane is operated by automatic control according to a preset program. In addition, the operation management table screen G5 distinguishes each operation, further distinguishes between the operation time and the number of operations and displays them by item, “Item” G502, G503 indicating the date, “Morning, daytime” described above , Night number ”G504,“ total ”G505,“ average ”G506, and the like are displayed.
For example, when the user accesses the general management center 1 to view the operation management table screen G5 of the crane remote monitoring service on March 3, 2011 shown in FIG. 9, the operation of the crane before March 3, 2011 You can know the time and number of operations.

(4. Operation monitoring)
Since the sequence showing the operation description related to the operation information acquisition process is the same as the sequence showing the operation description related to the operation time / number of times information acquisition process described above, the description thereof will be omitted.
When the first information disclosure unit 102b transmits the operation information to the user PC 3, the operation monitoring screen G6 shown in FIG. 10 is displayed on the monitor (not shown) of the user PC 3. On the operation monitoring screen G6, “equipment code” G601, “apparatus name” G602, “model” G603, “operation count” G604, “life count” G605, “previous replacement date” G606, and the like are displayed. As described above, among the items on the operation monitoring screen G6, information other than the “operation count” G604 is transmitted to the central management center 1 from the user PC 3 when first registered, and the second data The information acquisition unit 116 a stores the information in the operation information storage unit 107. Incidentally, the “number of operations” G604 means the total number of operations from the time when each device is installed on the crane to the present (time when the operation information is acquired).
In addition, when the user newly replaces each crane device, the user transmits information related to the replacement date to the central management center 1, and the second information acquisition unit 116 a uses the date of the “previous replacement date” G606 described above. Update.
Note that each of the above information is also stored in the device information storage means 108 corresponding to each device of the crane.

<Processing of maintenance management service and screen display example>
Next, the maintenance management service of the crane monitoring service will be described.
FIG. 11 is a sequence showing an operation description related to the device information acquisition process.
In step S401, the PC 3 transmits the user ID and password to the authentication server 113 via the network N2, and the authentication server 113 performs authentication processing in step S402. Then, the screen G2 shown in FIG. 4B is displayed on the monitor (not shown) of the user PC 3.
Furthermore, when the “maintenance management service” G202 shown in FIG. 4B is selected, the screen transitions to a screen (not shown) to which device information can be attached. The user designates a specific crane, and transmits information such as a device name, a device code, a model, a previous replacement date, and an inventory number of the crane as a file, for example, to the central management center 1 (step S403). .
In addition to the above items, the user may send detailed specifications, circuit design drawings, device images, and the like to the central management center 1.
The above processing is usually performed when the administrator of each crane base performs registration processing for the crane remote monitoring service.
In step S403 in FIG. 11, the user PC 3 transmits the device information to the second information acquisition unit 116a. Next, in step S404, the second information acquisition unit 116a stores the received device information in the device information storage unit 108 in association with the crane selected by the user.

In addition, when the user wants to browse the equipment information of the crane at the crane base to which the user belongs, the user performs the following process. That is, in step S405 in FIG. 11, the PC 3 transmits the user ID and password to the authentication server 113 via the network N2, and the authentication server 113 performs authentication processing in step S406. Next, in step S407, the user PC 3 transmits a device information acquisition command signal to the second information disclosure unit 116b. In this case, when there are a plurality of cranes at the crane base registered by the user, the user designates a specific crane among the plurality of cranes displayed on the screen (not shown) of the user PC 3.
In step S408, the second information disclosure unit 116b searches the device information stored in the device information storage unit 108 for the device information related to the crane specified by the user, and acquires the device information ( Step S409).
In step S410, the second information disclosure unit 116b transmits the device information to the user PC 3.

Incidentally, in the equipment information storage means 108, information on crane bases (see FIG. 12 (a)), information on cranes existing at each crane base (see FIG. 12 (b)), and equipment installed in each crane. Information (see FIG. 13) is stored in a database format.
That is, as shown in FIG. 12A, in the crane base database, “crane base name” G701 and “base code” G702 are associated with each other. Also, as shown in FIG. 12B, in the crane database, the “crane name” G703 and “crane code” G704 of the cranes existing at the respective crane bases are associated with each other.

When the second information disclosing unit 116b transmits the device information to the user PC 3 in step S410 of FIG. 11 described above, for example, the maintenance management service display screen G7 shown in FIG. 13 is displayed on the monitor (not shown) of the user PC 3. Displayed).
On the maintenance management service display screen G7, device information installed on the crane designated by the user among the crane bases to which the user belongs is displayed. For example, the maintenance management service display screen G7 includes “device name” G705, “device code” G706, “model” G707, “operation count” G708, “life count” G709, “alarm history” G710, “previous inspection date” "G711", "Inspection result" G712, "Previous replacement date" G713, "Next replacement scheduled date" G714, "Stock quantity" G715, etc. are displayed. Incidentally, the “number of operations” G708 means the total number of operations from the time when each device is installed on the crane to the present (time when the operation information is acquired).
In addition, for example, when a specific device name (for example, main power supply relay) is selected from among a plurality of device names displayed in FIG. 13, a detailed circuit diagram around the device may be displayed on the screen. Moreover, it is good also as displaying related information, such as a specification sheet and a photograph of the equipment of each crane on a screen.
Incidentally, although FIG. 13 shows an example in which each item G705 to G715 is displayed on one screen, for example, information screens for alarms, inspection information, replacement dates, etc. for each device are displayed as separate screens. It is also possible to make it.

<Documents created at the service center>
FIG. 14 is a diagram showing a comparison result of the number of operations of the traverse brake switch. The graph shown in FIG. 14 is created by, for example, the administrator of the service center 5 in order to present the graph as a document to the administrator of each crane base. Referring to the graph shown in FIG. 14, among the three cranes existing at a certain crane base, the crane No. No. 3 traverse brake switch has a small cumulative number of operations. It can be seen that the number of cumulative operations of 1 traverse brake switch is large.
For example, when the crane is moved manually instead of automatically, the number of traverse brake operations differs depending on the crane operator as described above. Then, among the plurality of cranes, the equipment constituting the specific crane is quickly worn out, and there is a situation that is inconvenient for the manager of the crane base, for example, there is a deviation in the replacement time of the equipment. That is, in general, when there are a plurality of cranes, it is desirable to reduce the difference in the number of operations of the devices constituting each crane.

The service center 5 presents the materials as shown in FIG. 14 to the manager of the crane base, so that the manager of the crane base responds to reduce the difference in the number of operations of the devices constituting each crane. Is possible.
In the above description, the screen shown in FIG. 14 cannot be viewed from the user PC 3. However, the overall management center 1 may provide a service for causing the user PC 3 to display the screen by the following method. Is possible. That is, first, the information analysis unit 109 reads the operation information of each device constituting each crane stored in the operation information storage unit 104, calculates the cumulative number of operations for each date, etc., and stores it in a storage unit (not shown). Store. Then, the first information disclosure unit 102b acquires the analysis result information from the storage unit in accordance with the instruction from the user PC3, thereby displaying the screen shown in FIG. 14 on the monitor (not shown) of the user PC3. Also good.

<Effect>
According to the management system A according to the present embodiment, the user should prepare only a minimum connection environment (PC3, mobile terminal, browser, communication means, etc.), and the management center 1 manages the cranes. Can be done in a lump. Therefore, crane monitoring information and equipment information can be provided to the user without making a major change to the existing crane equipment at each crane base.
In addition, the management system A according to the present embodiment is a cloud computing system that can use services provided by a server group existing on a network without being aware of the server group. Therefore, the user is given an ID and password corresponding to the crane base registered by the user, and can connect to the cloud computing network and grasp the crane status in real time as long as there is an internet connection environment.

Further, according to the management system A according to the present embodiment, detailed operation information of the crane is stored in the storage units 104 to 109 of the overall management center 1, so that the storage device having a huge storage capacity at each crane base. This eliminates the need to install a crane and reduces costs at each crane site.
In addition, the manager of the crane base, etc. wants to grasp information according to the purpose in an easy-to-understand manner when monitoring and maintaining each crane. According to the present invention, as shown in FIG. 4 (b), first, an “equipment monitoring service” (that is, a service that allows browsing of history of crane operation information up to the present) and a “maintenance management service” (that is, , A service that allows browsing of information relating to the necessity of replacement of the equipment constituting the crane, etc.) can be selected, and a screen corresponding to the purpose can be browsed.
Further, for example, by browsing the operation status screen shown in FIG. 5, the user can clearly understand the current state of the crane. That is, since detailed information is intentionally discarded on the operation status screen shown in FIG. 5, the user can easily grasp the current status of the crane.

Further, for example, by browsing the alarm list screen shown in FIG. 7, the user can grasp alarm information and diagnostic information, crane position information at the time of alarm occurrence, and the details of each crane at each time. It is also possible to grasp the operation history.
Conventionally, when a crane breaks down, the crane operator first contacts the crane administrator, and then the crane administrator contacts the support center to request maintenance. It took very much.
On the other hand, in the management system A according to the present embodiment, as shown in step S206 in FIG. 6, when the information analysis unit 109 receives the alarm information, the information is immediately transmitted to the management PC 52 (see FIG. 1). Therefore, the administrator of the service center 5 can grasp the alarm information and the diagnostic information at almost the same timing as when the alarm is generated at the site of the crane base. And the information regarding a crane can be shared between a user and the service staff of the service center 5 in real time.
As a result, when the crane breaks down, it is possible to make an inquiry to the crane base from the service center 5 side by using e-mail or telephone, and the burden on the crane base manager or the like can be greatly reduced.

Conventionally, the larger the number of cranes at a crane base, the greater the management burden of the equipment that constitutes the crane. In other words, when the crane has reached the end of its life or for replacement due to a failure, it is necessary to have a stock of equipment in advance at the crane base, but because the life of the equipment changes depending on the type of equipment, operation history, failure details, etc. It was necessary to give some margin to the number of stock.
On the other hand, the management system A according to the present embodiment collectively manages each piece of information using a plurality of servers using a cloud computing system, and performs various analyzes based on the acquired information. be able to. For example, as shown in FIG. 13, the next scheduled replacement date of each device can be presented based on the type and number of operations of each device, alarm history, inspection details, and the like. Therefore, at the crane base, by referring to the maintenance management service display screen G7 shown in FIG. 13, the stock status can be easily grasped and the number of stocks can be minimized.

  In addition, since the management system A according to the present embodiment includes the authentication server 113 (see FIG. 2), only the user whose validity is confirmed by the authentication server 113 can acquire information on the crane that exists at his crane base. You can browse. Furthermore, the management system A includes a plurality of F / Ws 103, 114a, 114b, and 117 (see FIG. 2), and includes a first information disclosing unit 102b (see FIG. 2) and a second information disclosing unit 116b (see FIG. 2). Each of the monitoring information and device information corresponding to the user ID is disclosed to the user. Therefore, it is possible to prevent leakage of information related to the crane from the management system A to outsiders and users of crane bases that do not correspond to the user ID.

Moreover, the manager of a crane base etc. wants to equalize the maintenance cost for every predetermined period. According to the management system A, it is possible to easily grasp which crane should be preferentially maintained based on the alarm history, the number of operations, the operation time, and the like. That is, according to the management system A, the maintenance priority can be set for each crane that is the object of maintenance, so the manager of the crane base etc. makes an appropriate maintenance plan for each crane. be able to.
