--- About attendance and attendance management in the worker management system ---
In the worker management system configured as described above, the attendance of the worker 8 and the operator is managed as follows. When the worker 8 or the operator 10 arrives at the construction site after attending work, he / she attaches information on the current position detected by the mobile telephones 6 and 7 and sends an e-mail from the mobile telephones 6 and 7 to the server. 3 is sent to. In addition, when the construction site is divided into several areas, an e-mail is transmitted from the area where the worker 8 or the operator 10 should work on the day. .

  The CPU 3a of the server 3 performs the following processing with the reception of an e-mail attached with information on the current position transmitted from the mobile phones 6 and 7 as a trigger. This process will be described with reference to the flowchart shown in FIG. FIG. 7 is a flowchart showing the operation of attendance / leaving management in the server 3. When an e-mail attached with information on the current position transmitted from the cellular phones 6 and 7 is received, a program for performing the process shown in FIG. 7 is started and executed by the CPU 3a. When an e-mail attached with information on the current position transmitted from the cellular phones 6 and 7 is received, the e-mail address of the sender of the received e-mail is read, and the e-mail address field of the worker data table 20 shown in FIG. The worker ID is identified by collating with the mail address stored in 20d (step S101).

  Next, the CPU 3a reads the entry / exit flag for the identified worker ID from the entry / exit flag column 20e of the worker data table 20, and whether or not the worker with the identified worker ID is working. Is determined (step S103). If the entrance / exit flag is 0, it indicates that the worker 8 or the operator 10 is before work (after work), and if the entrance / exit flag is 1, the worker 8 or the operator 10 is after work (work) Middle).

--- When the entrance / exit flag is 0 ---
Here, if the entrance / exit flag is 0 (No at Step S103), the CPU 3a determines whether or not the received e-mail is transmitted after the worker 8 (or the operator 10) arrives at the correct work area. That is, it is determined whether or not the worker 8 (or operator 10) who sent the e-mail is at the correct position (work area) (step S111). Specifically, the CPU 3a, from the construction plan data table 22 shown in FIG. 5, from the area column 22c and the charge column 22d for the day (that is, the email reception date), the worker 8 ( Alternatively, the operator 10) specifies a work area where the work should be performed. Next, the CPU 3a specifies the position (range) of the specified work area from the work area ID and the coordinate data stored in the work area data table 21 shown in FIG. Then, the CPU 3a determines whether or not an e-mail has been transmitted from the range of the specified work area based on the information on the current position attached to the received e-mail.

  When it is determined that an e-mail has been transmitted from within the specified work area (Yes in step S111), the CPU 3a sets the time when the e-mail is received (or the e-mail transmission time) as the start time (entry time). Assuming that there is data, the entry time column 23b for the worker ID in the attendance / attendance management data table 23 of FIG. 6 stores the data of the time when the e-mail was received (or the e-mail transmission time) (step S113). Next, the CPU 3a stores the entry / exit flag for the worker ID in the worker data table 20 of FIG. 3 as 1 in the entry / exit flag column 20e (step S115). As a result, the worker 8 (or operator 10) who sent the e-mail is treated as having gone to work.

  And CPU3a returns the information regarding the work content of the day with an email (step S117). Specifically, the CPU 3a, from the construction plan data table 22 shown in FIG. 5, the worker 8 to which the worker ID is assigned from the work content column 22b and the charge column 22d for that day (that is, the e-mail reception date). (Or operator 10) specifies the work content to be worked on. Then, the CPU 3a generates an e-mail including information about the identified work content and sends it back to the mobile phones 6 and 7 that are the sender of the received e-mail.

  If it is determined that an e-mail has been transmitted from outside the specified work area (No at step S111), the CPU 3a returns information about the correct work area by e-mail (step S121). Specifically, the CPU 3a, from the construction plan data table 22 shown in FIG. 5, from the area column 22c and the charge column 22d for the day (that is, the email reception date), the worker 8 ( Alternatively, the operator 10) specifies a work area where the work should be performed. Next, the CPU 3a specifies the position (range) of the specified work area from the coordinate data stored in the work area data table 21 shown in FIG. Then, the CPU 3a generates an e-mail including information about the position (range) of the specified work area, and sends it back to the mobile phones 6 and 7 that are the sender of the received e-mail.

--- When the entrance / exit flag is 1 ---
If the entrance / exit flag is 1 in step S103 described above (Yes determination in step S103), the CPU 3a regards the time when the e-mail is received (or the e-mail transmission time) as the end time (exit time). The data of the time when the e-mail is received (or the e-mail transmission time) is stored in the leaving time column 23c for the worker ID in the attendance / leaving management data table 23 of FIG. 6 (step S105). Further, the CPU 3a calculates a working time for the worker ID based on the entrance time and the leaving time, and stores the calculated working time in the working time column 23d.

  Next, the CPU 3a stores the entry / exit flag for the worker ID in the worker data table 20 of FIG. 3 as 0 in the entry / exit flag column 20e (step S107). Thereby, the worker 8 (or the operator 10) who transmitted the electronic mail is treated as having left (returned home). And CPU3a returns the information regarding the work content of a next construction day, a work area, etc. with an email (step S109). Specifically, the CPU 3a, from the construction plan data table 22 shown in FIG. 5, from the work content column 22b, the area column 22c, and the charge column 22d for the next construction date (that is, the next construction date on the e-mail reception date). The worker 8 (or the operator 10) to whom the worker ID is assigned identifies the work content and work area to be worked. Next, the CPU 3a specifies the position (range) of the specified work area from the coordinate data stored in the work area data table 21 shown in FIG. Then, the CPU 3a generates an e-mail including information on the next construction date, work contents, the position (range) of the specified work area, and the like to the mobile phones 6 and 7 that are the sender of the received e-mail. Send back.

--- About the e-mail transmission function in the server 3 ---
As described above, the server 3 has a function of transmitting an electronic mail, but can transmit various electronic mails based on various conditions designated from the server 3 side or the PC 5 side of the field office 4. For example, referring to the information stored in the worker data table 20 shown in FIG. 3 or the construction plan data table 22 shown in FIG. 5 as an email destination, a mail assigned with a specific worker ID. An address can be specified. For example, all e-mail addresses belonging to any attribute of the worker 8 (operator 10) such as whether the worker 8 or the operator 10 can be designated as the transmission destination of the e-mail. For example, as e-mail transmission destinations, e-mail addresses for all worker IDs that are supposed to be in charge of a specific work area can be designated.

  In addition, the transmission content of an electronic mail can be made into arbitrary content. Further, a predetermined fixed sentence may be transmitted by e-mail. For example, when the weather changes suddenly, for example, the worker 8 or the operator 10 engaged in a specific work content in a specific work area, or all the workers 8 in all the work areas When notifying the operator 10 of the suspension of work, the above-described e-mail transmission function of the server 3 can be used.

--- Processing at PC 5 in the field office 4 ---
The PC 5 in the field office 4 can access the server 3 in the data center 2 via the Internet network 1 and read necessary information from the database in the server 3. For example, the PC 5 can read the worker data table 20 shown in FIG. 3 from the database in the server 3 and display it on the monitor 5g. Further, the PC 5 can read the attendance and attendance management data table 23 shown in FIG. 6 from the database in the server 3 and display it on the monitor 5g. Thereby, the supervisor of the field office 4 can confirm the attendance / leaving status of the worker 8 and the operator 10.

  The data stored in the work area data table 21 shown in FIG. 4 can be input by using an input device such as a keyboard 3h on the server 3 side, but may be input on the PC 5 side. In other words, the work area data table 21 may be created or modified on the PC 5 side by using an input device such as a keyboard 5 h and transferred to the server 3 via the Internet network 1.

  The data stored in the construction plan data table 22 shown in FIG. 5 can be input on the server 3 side by using an input device such as a keyboard 3h, but may be input on the PC 5 side. That is, on the PC 5 side, the construction plan data table 22 may be created or modified by using an input device such as a keyboard 5 h and transferred to the server 3 via the Internet network 1.

  As described above, the PC 5 can set various conditions regarding the electronic mail transmitted from the server 3 side. In addition, you may make it give the function equivalent to the electronic mail transmission function of the server 3 mentioned above on the PC5 side.

The worker management system according to the first embodiment described above has the following effects.
(1) The current position is detected by the cellular phones 6 and 7 carried by the worker 8 or the operator 10, and an e-mail including information on the detected current position is transmitted to the server 3 at the time of going to work or leaving work, thereby 8 and operator 10 attendance and leaving work are configured to be managed. Therefore, even in places where the terrain and work place frequently change, as in the case of construction sites, it is not necessary to install a gate or the like and to place an observer, so that an appropriate attendance management system can be realized. Thereby, the attendance and attendance management at the construction site can be made efficient.

(2) When the worker 8 or the operator 10 sends an e-mail from the outside of the work area determined in the construction plan at the time of work by using the mobile phones 6 and 7, the server 3 sends back information on the correct work area by e-mail. Configured. Thereby, it is possible to guide the worker 8 and the operator 10 who have mistakenly arrived to the correct work area where they should originally arrive, and to prevent deterioration of work efficiency.

(3) When the worker 8 or the operator 10 sends an e-mail from the work area determined in the construction plan at the time of work to the mobile phone 6 or 7, the server 3 sends back information on the work contents of the day by e-mail. It was configured as follows. Thereby, the worker 8 and the operator 10 can reconfirm the work contents of the day, which contributes to improvement of work efficiency.

(4) The configuration is such that when the worker 8 or the operator 10 sends an e-mail with the mobile phones 6 and 7 when leaving the office, the server 3 sends back information on the work content, work area, etc. of the next construction day by e-mail. . Thereby, the work content and work area of the next construction day (next work day) can be notified to the worker 8 or the operator 10, which contributes to improvement of work efficiency.

(5) The time when the e-mail is received at the server 3 or the time when the e-mail is transmitted by the mobile telephones 6 and 7 is regarded as the entrance time and the exit time. The table 23 is configured to be stored in the entry time column 23b and the exit time column 23c. Thereby, management of the entrance time and exit time of the worker 8 and the operator 10 can be facilitated.

(6) The server 3 receives information on the current position detected by using the GPS signals from the GPS satellites by the mobile phones 6 and 7 equipped with a so-called GPS function. As a result, it is possible to accurately detect that the worker 8 or the operator 10 has gone to work in a predetermined work area with a simple configuration, and thus it is possible to suppress an increase in the cost of building a worker management system. In addition, it is possible to suppress fraudulent acts that appear as if the worker 8 or the operator 10 is not working, and the working state of the worker 8 or the operator 10 can be kept good.

(7) Using the database constructed in the server 3, various e-mails can be transmitted based on various conditions designated from the server 3 side or the PC 5 side of the field office 4. As a result, it is possible to appropriately select a partner to be contacted by e-mail and transmit the e-mail, so that information can be efficiently and effectively transmitted to the worker 8 and the operator 10.

--- Second embodiment ---
With reference to FIGS. 8-11, 2nd Embodiment of the worker management system by this invention is described. In the following description, the same components as those in the first embodiment are denoted by the same reference numerals, and different points will be mainly described. Points that are not particularly described are the same as those in the first embodiment. This embodiment is different from the first embodiment in that information obtained from the construction machine 9 at the construction site is mainly used.

  That is, in the first embodiment, the worker 8 or the operator 10 and the work area are associated with each other. In the worker management system of the second embodiment, the worker 8 or the operator 10 and the construction machine are connected. 9 is managed by linking. This will be described in detail below. FIG. 8 is a diagram illustrating an overall configuration of the worker management system according to the second embodiment. 11 is a communication satellite, 12 is a heavy equipment data center for receiving various information transmitted from the construction machine 9, and 13 is a server provided in the heavy equipment data center 12.

  Various information of the construction machine 9 collected by a control device (not shown) of the construction machine 9 is transmitted to the server 13 of the heavy equipment data center 12 via the communication satellite 11. For example, when the construction machine 9 is a hydraulic excavator, examples of data transmitted from the hydraulic excavator to the server 13 include the following data. For example, as daily report data, hydraulic excavator position information, engine key switch on / off time, engine start time, engine stop time, hour meter measurement value, travel operation time, turning operation time, front operation time, engine operation There is a time distribution.

  Daily report data includes travel load frequency distribution, excavation operation time distribution or fuel consumption (per unit time, operation, no load, etc.). The alarm data includes engine oil level, engine coolant temperature, engine oil temperature, air filter clogging, hydraulic oil filter, battery voltage, engine oil pressure, fuel remaining amount, hydraulic oil temperature, and the like. Fault data includes abnormal engine speed, abnormal discharge pressure of the hydraulic pump, and the like.

  The heavy equipment data center 12 is provided with the server 13 as described above. The server 13 receives various information transmitted from the construction machine 9 via the communication satellite 11 and records it in a recording device (not shown). The server 13 is connected to the Internet network 1.

  The server 3 of the data center 2 and the PC 5 of the field office can obtain various information of the construction machine 9 by connecting to the server 13 of the heavy equipment data center 12 via the Internet network 1. When the server 3 obtains information on the position of the construction machine 9, the server 3 creates a construction machine database data table (construction machine data table) 24 as shown in FIG.

  In the construction machine data table 24, a construction machine ID column 24a, a latitude column 24b, and a longitude column 24c are provided for each construction machine ID. The construction machine ID column 24a is a column in which an identifier (construction machine ID) for identifying each construction machine 9 is stored. The latitude column 24b and the longitude column 24c are columns in which the latitude and longitude information of the construction machine 9 obtained from the position information of the construction machine 9 is stored.

  Moreover, the server 3 creates the construction plan data table 25 of the construction plan database as shown in FIG. In the construction plan data table 25, a date column 25a, a work content column 25b, a construction machine ID column 25c, and a charge column 25d are provided for each date. The date column 25a is a column in which data of construction date (construction date) is stored. The work content column 25b is a column in which data related to construction content is stored.

  The construction machine ID column 25c is a column in which the construction machine ID of the construction machine 9 that performs the work on the construction date stored in the date column 25a is stored. The work column 25d is a work for performing work on or around the construction machine 9 with the construction machine ID stored in the construction machine ID column 25c on the construction date stored in the date field 25a. This is a column for storing the worker ID of the worker 8 or the operator 10. Therefore, the construction plan data table 22 stores information on construction plans (construction management), which work contents, which construction machines 9 and who are scheduled to work. Thus, in the worker management system of the present embodiment, the worker 8 or the operator 10 and the construction machine are linked.

--- About attendance and attendance management in the worker management system ---
In the worker management system configured as described above, the attendance of the worker 8 and the operator is managed as follows. When the worker 8 or the operator 10 arrives at the construction site after coming to work, an e-mail is attached from the mobile phones 6 and 7 to the server 3 with information on the current position detected by the mobile phones 6 and 7 being carried. Send to. In addition, when the construction site is divided into several areas, an e-mail is transmitted from the area where the worker 8 or the operator 10 should work on the day. .

  The CPU 3a of the server 3 performs the following processing with the reception of an e-mail attached with information on the current position transmitted from the mobile phones 6 and 7 as a trigger. This process will be described with reference to the flowchart shown in FIG. FIG. 11 is a flowchart showing the operation of attendance / leaving management in the server 3. When an e-mail attached with information on the current position transmitted from the cellular phones 6 and 7 is received, a program for performing the processing shown in FIG. 11 is started and executed by the CPU 3a. When an e-mail attached with information on the current position transmitted from the cellular phones 6 and 7 is received, the e-mail address of the sender of the received e-mail is read, and the e-mail address field of the worker data table 20 shown in FIG. The worker ID is identified by collating with the mail address stored in 20d (step S101).

  Next, the CPU 3a reads the entrance / exit flag for the specified worker ID from the worker data table 20, and determines whether or not the worker with the specified worker ID is working (step). S103). Note that the processing content executed in step S101 and step S103 is the same as the processing content executed in step S101 and step S103 in FIG. 7 of the first embodiment.

--- When the entrance / exit flag is 0 ---
Here, if the entrance / exit flag is 0 (No at Step S103), the CPU 3a determines whether or not the received e-mail is transmitted after the worker 8 (or the operator 10) arrives at the correct work area. That is, it is determined whether or not the worker 8 (or operator 10) who transmitted the e-mail is in the correct position (work area) (step S131). Specifically, the CPU 3a, from the construction plan data table 25 shown in FIG. 10, the worker assigned the worker ID from the construction machine ID column 25c and the responsible column 25d for that day (that is, the e-mail reception date). 8 (or operator 10) specifies the construction machine 9 with which work should be performed. Next, the CPU 3a specifies the location of the specified construction machine from the latitude and longitude data stored in the construction machine data table 24 shown in FIG. Then, the CPU 3a determines whether or not an e-mail has been transmitted from a predetermined range centered on the specified location of the construction machine 9, based on the information on the current position attached to the received e-mail. .

  When it is determined that an e-mail has been transmitted from within a predetermined range centered on the specified location of the construction machine 9 (Yes in step S131), the CPU 3a receives the e-mail (or e-mail transmission time). ) Is regarded as the start time (entrance time), and the entry time column 23b for the worker ID in the attendance management data table 23 in FIG. Data is stored (step S113). Henceforth, since operation | movement of step S115 and step S117 is the same as operation | movement of step S115 and step S117 of FIG. 7 in 1st Embodiment, detailed description is abbreviate | omitted.

  If it is determined that an e-mail has been transmitted from outside the predetermined range centered on the location of the specified construction machine 9 (No in step S131), the CPU 3a returns an e-mail with information on the correct work area. (Step S141). Specifically, the CPU 3a, from the construction plan data table 25 shown in FIG. 10, the worker assigned the worker ID from the construction machine ID column 25c and the responsible column 25d for that day (that is, the e-mail reception date). 8 (or operator 10) specifies the construction machine 9 with which work should be performed. Next, the CPU 3a specifies the location of the specified construction machine from the latitude and longitude data stored in the construction machine data table 24 shown in FIG. And CPU3a produces | generates the electronic mail containing the information about the location of the specified construction machine, and returns it to the mobile telephones 6 and 7 which are the transmission origin of the received electronic mail.

--- When the entrance / exit flag is 1 ---
In step S103 described above, if the entrance / exit flag is 1 (Yes determination in step S103), the CPU 3a performs the processing shown in and after step S105. Note that the operations in step S105 and step S107 are the same as the operations in step S105 and step S107 in FIG. 7 in the first embodiment, and thus detailed description thereof is omitted.

  If step S107 is performed, CPU3a will reply with the information regarding the work content of a next construction day, a work area, etc. with an email (step S159). Specifically, the CPU 3a determines from the construction plan data table 25 shown in FIG. 10 a work content column 25b, a construction machine ID column 25c, and a responsible column for the next construction date (that is, the next construction date on the e-mail reception date). From 25d, the worker 8 (or the operator 10) to whom the worker ID is assigned specifies the work content to be worked on and the construction machine 9 to be worked on together. Next, the CPU 3a specifies the location of the specified construction machine from the latitude and longitude data stored in the construction machine data table 24 shown in FIG. And CPU3a produces | generates an email containing the information regarding the next construction date, work content, the location position of the specified construction machine, etc., and replies to the mobile telephones 6 and 7 which are the transmission origin of the received email. .

  In addition, as mentioned above, in order to return the information regarding the work area of the next construction date by e-mail in step S159, the construction machine 9 becomes the work area of the next construction date at the time of creation of the e-mail. It is necessary to move. If it is considered that the construction machine 9 has not moved to the work area on the next construction date at the time of creation of the e-mail, the work area on the next construction date is sent to the reply e-mail in step S159. It is desirable not to include information about.

In the worker management system of the second embodiment described above, the following operational effects are obtained in addition to the operational effects of the first embodiment.
(1) Instead of information on the position (range) of the work area in the first embodiment, the location of the construction machine 9 is used. As a result, it is possible to save the trouble of inputting data in the work area, and it is possible to improve the work attendance management at the construction site.

---- Modification ---
(1) In the above description, the worker 8 and the operator 10 are configured to transmit an e-mail including information on the current position from the mobile phones 6 and 7 when going to work and leaving work. It is not limited. For example, in order to prevent the worker 8 and the operator 10 from leaving the office without permission during work, an e-mail including information on the current position is also sent before and after lunch break, and in the morning and afternoon breaks. You may do it.

(2) In the above description, the worker 8 and the operator 10 perform an operation of transmitting an e-mail from the mobile phones 6 and 7, but the present invention is not limited to this. For example, when the server 3 of the data center 2 inquires each mobile phone 6, 7 about the current position, each mobile phone 6, 7 automatically detects the current position and returns the detection result to the server 3. You may comprise.

(3) In the second embodiment described above, when an e-mail is transmitted from the mobile phone 6 or 7 carried by the worker 8 or the operator 10, the CPU 3a is stored in the construction machine data table 24 shown in FIG. Although the location of the construction machine 9 is specified from the latitude and longitude data, the present invention is not limited to this. For example, when an e-mail is transmitted from the mobile phones 6 and 7 carried by the worker 8 or the operator 10, the server 3 of the data center 2 inquires the server 13 of the heavy equipment data center 12 about the location of the construction machine 9. It may be configured.

For example, a mail server may be provided outside the worker management system according to the present invention, for example, using a mail service provided by an Internet service provider that is an external supplier.

(7) In the above description, information on the work contents of the day is returned by e-mail to the mobile phones 6 and 7 carried by the worker 8 and the operator 10 arriving at the correct work area (see FIGS. 7 and 11). Although configured as step S117), the present invention is not limited to this, and it is not indispensable to return information on the work contents of the day by e-mail.

(8) In the above description, whether the worker 8 or the operator 10 has arrived at the correct work area by receiving the current position information detected by using the so-called GPS function of the mobile phones 6 and 7 at the server 3. Although it was configured to determine whether or not, the present invention is not limited to this. For example, instead of receiving a radio wave from a GPS satellite and detecting a current position, a technique for detecting a current position by receiving a radio wave from a wireless LAN communication device (access point) registered in advance (for example, PlaceEngine ( Other techniques for detecting the current position, such as registered trademark)) may be used.

(9) In the first embodiment described above, whether the worker 8 or the operator 10 has arrived at the correct work area has arrived in the vicinity of the work area associated with the worker 8 or the operator 10. It was configured to judge based on whether or not In the second embodiment described above, whether the worker 8 or the operator 10 has arrived at the correct work area has arrived in the vicinity of the work machine 9 associated with the worker 8 or the operator 10. It was configured to judge based on whether or not However, the present invention is not limited to this. For example, whether or not the worker 8 has arrived at the correct work area is determined based on whether or not the worker 8 has arrived in the vicinity of the work area associated with the worker 8, and the operator 10 has arrived at the correct work area. It may be configured to determine whether or not it has arrived in the vicinity of the work machine 9 associated with the operator 10.

(10) In the above description, when the worker 8 or the operator 10 leaves the office, it is not determined whether or not an email is transmitted from the correct work area. However, even when the worker leaves the office, the email is transmitted from the correct work area. You may comprise so that it may be judged whether it is what was done. For example, if an e-mail is sent from the correct work area at the time of leaving work, it is assumed that the work has been done until the end time, and the time when the e-mail is received (or the e-mail transmission time) is regarded as the exit time. Also good. Further, if the e-mail is not transmitted from the correct work area at the time of leaving work, it may be assumed that the work area has been left before the closing time, for example, that it is treated as early leave.
(11) Each embodiment and modification described above may be combined.
