Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a work management system for managing on-site work of railway equipment (railway equipment and power equipment), and in particular, communication between a central power command system and a work site and blackout / pressurization control of a work section. About.
[0002]
[Prior art]
The power command system that performs on-site power failure / pressurization control of railway electrical facilities and the work site are managed and operated in the following manner.
[0003]
(1) Application for on-site work and contact with the power command system are confirmed and instructed by conversation using telephones between the system operator and the field work person.
[0004]
(2) Prior to the start of on-site work, power outage control of the electrical equipment is performed in advance from the power command system, and permission to start work is given by telephone contact with the site after the power outage is completed. To prevent accidental pressurization at the place where the power was lost, lock the substation (a lock mechanism that prevents the device from operating even when a control command is issued).
[0005]
(3) There are the following types of telephone contact with the local site, which are operated by having a conversation for each work. (A) Arrival on site, (b) Start work, (c) End work, (d) Raise the field.
[0006]
(4) When the above-mentioned “work completion” notification is made after the work on site is completed, the power command system releases the lock of the substation and performs pressurization control of the facility that has lost power. However, pressurization control is not performed when other work continues for the equipment.
[0007]
(5) On-site, check after completion of work, and notify the power command system side of the lifting.
[0008]
The telephone communication in the above procedure uses a dedicated railway telephone line or public telephone line (NTT or the like), and a mobile phone or PHS using a mobile communication system is also used as a telephone.
[0009]
As another work communication method, Japanese Patent Application Laid-Open No. 8-265969 uses a voice recognition device for communication of work procedures for power system equipment inspection and the like, and the central command side sends voice messages according to the work procedures. A system has been proposed that confirms the content of a communication by sending it to the site and recognizing the response from the person in charge at the site. In addition, the contents of communication may be recorded.
[0010]
In addition, as another communication method, Japanese Patent Application Laid-Open No. 9-282027 discloses that when an abnormality of a monitoring target of a plant is detected, the center automatically performs dialing from the center to notify the abnormality content with a voice synthesized voice, On the site side, a device has been proposed that sends confirmation of abnormal content to the center using different push buttons.
[0011]
In addition, recent telephone devices can use mobile systems (having a function to send and receive character information and image information in addition to voice information), and the above-mentioned work communication also uses character information by pen input characters or predetermined message characters. It is possible to use image information taken with a digital camera or the like.
[0012]
[Problems to be solved by the invention]
(1) On-site work on the railway is performed during the night time (called a time interval) when the train does not run, so it is concentrated in the same limited time zone. For this reason, when all of the work instructions on the power command system side and the local work are made by telephone, the work is confirmed and instructed every time, so the burden on the operator on the power command system side becomes very large.
[0013]
For example, more than 50 tasks per day are concentrated from about 1 am to 4 am, and in the same section (when a power failure occurs on the up and down lines like a train line, When a plurality of operations are performed in the case of a power failure in the section), the judgment work of the operator on the power command system side is very important and requires a reliable response, and the burden becomes very large.
[0014]
In the method using the conventional voice recognition device, the voice recognition level is limited to a specific word registered in advance (such as “high”, “yes”, “wari”, etc.), and continuous numbers such as work numbers and work procedures are not recognized. This can be difficult and can lead to incorrect contact.
[0015]
(2) In the case of telephone contact from the local area, there are multiple tasks related to the operation, and the operator relies on the person's real voice for the recognition of the local operator. There is a risk of contacting other work contents.
[0016]
In addition, when the conventional speech recognition device and speech synthesis device are used, the voice quality is inferior to that of a normal telephone, and it becomes very difficult to identify the person in charge of the worker.
[0017]
(3) In response to the start / end notification of the local work, the power command system controls the lock and release of the device separately, and checks the congestion relationship with other work and manages the time. It takes time to do it.
[0018]
The above problems are caused by the fact that there is no method that can automatically recognize the person in charge of the local work accurately, and that there is no mechanism that automatically recognizes the telephone conversation by the CPU of the power pointing system. .
[0019]
When using a mobile system for work communication and combining text information and image information with voice information, the burden on the operator can be reduced and misrecognition can be reduced. Requires a lot of manipulation. In addition, in order to send a wide variety of information, information processing equipment such as a notebook personal computer is required on the site side, which is larger than a contact method using only a telephone.
[0020]
The object of the present invention is that the site side can be contacted only by a mobile phone, and furthermore, the contact can be made surely and easily even in a congested work, and the power system power failure / pressurization can be automatically controlled in conjunction with the field work. It is to provide a work management system for railway facilities.
[0021]

[0027]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a main part configuration diagram of a power command system showing an embodiment of the present invention. As with the conventional system, the operator on the system side and the local worker in charge use voices that pass through the telephone exchange networks 3 and 4 between the central telephone device 1 on the operator side and the mobile phone 2 on the worker side. A conversation is made possible.
[0028]
The I / O server 5 as the information processing apparatus main body is connected to other apparatuses via a LAN to perform a telephone linkage process. For this process, the power outage work support apparatus 6 acquires a planned power outage work application. The remote monitoring control device 7 enables monitoring and control of the power failure / pressurization state of the on-site power system, and the work processing device (telephone linkage device) 8 enables input / output of work communication information.
[0029]
Further, the I / O server 5 displays management information such as system status display and work status display with the operator control console 9 (CRT display device, keyboard, etc.) and operation input such as on-site call input from the operator. Can be accepted.
[0030]
The functional block of the I / O server 5 includes a power outage construction acceptance registration processing unit 5A, a power outage control processing unit 5B, a work acceptance processing unit 5C, and a power outage state check processing unit 5D. A processor and an internal memory and an external storage device for storing work information and display information are provided.
[0031]
The work information is acquired by the power outage construction acceptance registration processing unit 5A, and as shown in the example of the data format in FIG. 11, a plurality of work numbers for each construction number, telephone numbers for each work number, work It has a person name, a construction section, a work type, and a plurality of work tag numbers, which are input at the time of work application.
[0032]
The display information is created by the power failure control processing unit 5B with the display information from the remote monitoring control device 7, and has the data such as the open / close state of the circuit breakers at both ends of the construction section, and the power failure / pressurization state and the work described later The bill can be displayed as a railroad power system skeleton and symbolic figure.
[0033]
The information flow and function sharing of each part for the above-described telephone linkage processing are as shown in FIG. 2, and each part function and work management by these functions will be described in detail below.
[0034]
(1) Function of Work Processing Device FIG. 3 shows functional blocks of the work processing device. The telephone communication processing unit 8A performs line connection processing such as outgoing and incoming calls to the switching network 4 and voice signal modulation and demodulation processing. The telephone call processing unit 8B sends a call request from the I / O server 5 to the mobile phone 2 by instructing the phone communication processing unit 8A, and conversely, a reply from the mobile phone 2 through the phone communication processing unit 8A. The input is passed to the I / O server 5 as a notification result. The voice response processing unit 8C generates state inquiry information to the I / O server 5 by recognizing the telephone input from the mobile phone 2 through the telephone communication processing unit 8A, and conversely, the I / O server The state response information from 5 is synthesized by voice and sent back to the mobile phone 2 side by voice.
[0035]
Note that the processing information of the telephone call processing unit 8B and the voice response processing unit 8C is stored as logging information in the data file 8D. In addition, the data file 8D has a function of storing the telephone number of the caller in order to identify the caller and to collate with the power outage construction information.
[0036]
With such a configuration, the work processing apparatus performs the following processing in cooperation with the I / O server.
[0037]
The work processing device receives a call from the site and recognizes the caller's phone number by voice, and checks (checks) the wrong call by collating with the phone number of the work information registered in advance in the I / O server. In the case of an erroneous call, a guidance to that effect is transmitted from the work processing device to the person in charge of the work by speech synthesis.
[0038]
If the telephone number from the local site is correct, an input guidance is generated by synthesizing the work number in the work information of the I / O server, and the number input by the PB (push button) operation from the worker is accepted. The work number is a number automatically assigned when the work is applied, and is a number having a unique numbering and a check code for error prevention. After receiving the work number, an inquiry is made as to whether the work is registered in the I / O server or whether it is the work of the day.
[0039]
Next, the types of work communication “arrival on site”, “start of work”, “end of work”, and “lift on site” are accepted.
[0040]
Function after accepting work contact If the local work contact code (push button operation) is normal, the above type is notified to the I / O server, and processing corresponding to the work contact is performed.
[0041]
In addition, as for the telephone linkage line, an interface (IF) capable of taking a plurality of channels is prepared in the telephone linkage apparatus so that a plurality of lines can be simultaneously connected to the local telephone. It also has a multi-function that allows conversations simultaneously on multiple lines. In addition, the telephone link I / F can be connected to an NTT public line, a mobile phone, and a railway phone.
[0042]
In addition, the telephone call usually has an automatic conversation by connection from the site, but a function to automatically call the site from the command under the following conditions is also provided. After the local call, conversation is made with the automatically generated synthetic voice to prompt the contact from the local.
[0043]
(A) When the power failure control is delayed, after the power failure is completed, a “power failure completion notification” is automatically transmitted to the site to instruct the start of work.
[0044]
(B) If power transmission is not completed before the site is pulled up, the site is in a standby state. After that, when the power transmission control is completed with a delay, the local “power transmission completed” notification is made.
[0045]
(C) Call the site arbitrarily from the control console of the power command and prompt the contact to the command.
[0046]
(2) Functions of I / O server related to telephone linkage The I / O server provides the following functions for each telephone linkage by the processing units 5A to 5D in FIG.
[0047]
(A) Validity check of work number: The work reception processing unit 5C checks the work information to check whether the work number notified from the site is registered as the work of the day, whether the time is correct, etc., and processes the result. A call is made via the device 8 and the local telephone is answered by voice.
[0048]
(B) Acceptance of work type: The work reception processing unit 5C checks the type of contact from the local site (local arrival, work start, work end, site pull-up) and the correctness of the procedure.
[0049]
(C) Check of work start and lock control: As a condition before on-site work, the work acceptance processing unit 5 confirms that the power failure has been normally completed by the power failure control processing unit 5B and the power failure state check processing unit 5D. Confirm in advance, and if the power outage control has not ended normally, reject the work. When the power failure is completed, the power failure control processing unit 5B automatically performs lock control to the substation, and automatically places a work tag on the power failure location.
[0050]
The work tag displays a “tag” symbol in a detachable manner so that it can be recognized on the CRT screen with respect to the facility or substation that is performing the field work. This work tag makes it possible to know the number of works by the number of cases such as “work 2” when a plurality of works are congested.
[0051]
(D) Work completion acceptance and lock release control: The work acceptance processing unit 5C accepts the notification of the work completion, the power failure control processing unit 5B automatically controls the release of the lock, and the work tag placed on the relevant part is automatically Remove with. When a plurality of operations remain, the unlocking control is performed so that only the relevant device is unlocked.
[0052]
(E) Raising the site: The power failure state check processing unit 5D confirms the end of the power transmission control before raising the site, and accepts the raising if it is completed normally. If power transmission has not been completed, the standby is instructed by voice.
[0053]
(F) Status inquiry: The status of the work can be confirmed by telephone from the field. For the inquiry, the work number is input by PB and the result is returned by voice.
[0054]
When the work processing device 8 does not have a caller number recognition function, the I / O server recognizes that there is no call number at the work processing device at the time of input telephone connection with the push button of the telephone number and It is possible to prompt the input of the number by voice and wait for the input from the PB.
[0055]
(3) Details of Linkage Processing by Work Processing Device and I / O Server FIG. 4 shows a telephone linkage processing flow by the work processing device 8 and the I / O server 5. The work processing device 8 connects the line by calling from the site by the mobile phone 2 (S1), acquires the caller number, checks the telephone number of the registered trader and the wrong call (S2), In the case of a mistaken call, guidance such as “please call me back” is automatically sent out with synthesized voice (S3).
[0056]
If the telephone number from the site is correct, the input guidance of the contact type (work number) is played with synthesized voice, and the work number input from the PB (push button) is accepted (S4). For example, this information should be “No. 1 for local arrival, No. 3 for work start, No. 7 for work completion, No. 9 for local lifting, No. 0 for status inquiry” 3, 5, 7, 9, and 0 are numbers automatically assigned when the work is applied, and are numbers having a unique numbering and an error prevention check code.
[0057]
After receiving the work number, the work reception processing unit 5C of the I / O server 5 is inquired as to whether the work is registered or the work of the day. The work reception processing unit 5C refers to the work information received by the power outage construction work reception registration processing unit 5A so far and determines whether or not there is registration.
[0058]
If there is an illegal content in the input or confirmation of the contact type, the caller number and the work number are surely checked by repeating the exchange of the push button operation signal for guidance and confirmation by the synthesized voice.
[0059]
Next, if the local work contact code (PB) is normal at the work contact reception, the I / O server 5 is contacted, and the local arrival linkage process (S5) and work start (work start (work start) ) Link process (S6), work end link process (S7), local pull-up link process (S8) and status inquiry process (S9). These processes are managed by the transition shown in FIG.
[0060]
In FIG. 5, (a) the state before the arrival at the site is not yet arrived. In this state, the work state is changed to “arrival at the site” only when the arrival at the site is notified. (B) The state before “work start” is notified is “local arrival”, and when “work start” is notified in this state, the work state is changed to “working”. (C) If the power outage is not completed when “work start” is notified, the state is shifted to “standby (waiting for power outage)”. (D) When “working” is notified again in the “standby (waiting for power failure)” state, if the power failure has already been completed, the state is changed to “working”. (E) The state before the “work completion” is notified is “working”, and the work state is changed to “work completion” only when “work completion” is notified in the “working” state. (F) The state before “local pulling” is notified is “work completion”, and when “local pulling” is notified in the “work completion” state, the working state is shifted to “local pulling”. (G) If the power transmission is not completed when the “local pull-up” is notified, a transition is made to “standby (waiting for power transmission)”. (H) In the state of “standby (waiting for power transmission)”, if “powering up on site” is notified again, if power transmission has already been completed, transition is made to “uplifting on site”.
[0061]
