Department of statePrime minister wen jiabao chaired the standing meeting of the state council on 28 november to receive a briefing on the investigation of particularly important railway traffic accidents on the “7-23” hot line。
The meeting noted that the accident investigation team had been established by the state council immediately after the outbreak of a particularly major railway traffic accident on the “7-23” temperature line, and that the team had since been strengthened, as required by its work, with a restructuring of its personnel and an improved investigation system。
The restructured department of state accident investigation team, consisting of the relevant departments and local officials, engaged experts in the areas of rail transport, electricity, electrical, automation, communications, signals, security management and construction, and invited the supreme people's procuratorate to participate. Over the past few months, the investigation team, in accordance with the principles of scientific rigour, legal legality and realism, has carefully conducted on-site surveys, tests, technical validations, investigative forensics, comprehensive analysis and expert reasoning, identified the circumstances, causes, emergency disposals, casualties and direct economic loss of the accident, and identified the nature of the accident and its consequencesResponsibilityI don't know。
A particularly significant railway traffic accident on the “7-23” temperature line was found to be a liability caused by serious design defects in the equipment at the control centre, poor clearance of the upper road use review, and inadequate emergency disposal of equipment following a malfunction caused by lightning strikes。
The judiciary is conducting independent investigations, in accordance with the law, into whether those responsible are suspected of having committed a crime. The meeting decided to entrust the state council with the task of restructuring the communications and signals group corporation, communications and signals corporation ltd. And its subsidiary communications and signals research and design institute, in accordance with the law, and of reorganizing the communications and signals research and design institute。
Reason analysis
The incident occurred as a result of a breakdown in the management of equipment development at the lkd2-t1 control centre by the communications and signals group corporation, which is a subsidiary of the communications and signals group corporation, and its inability to perform its duties as the general contractor for the integration of communications signals from the temperature line, which resulted in serious design defects and significant security risks for the equipment provided for the southern station in win state, the hot line. The ministry of railways has made it possible to use the lkd2-t1 column control centre because of irregularities in the bidding, technical examination, use of the upper track, etc. Thunderbolts caused malfunctions in the equipment and orbital circuits of the control centre, and the wrong control signals showed that the vehicle was unsafe. The shanghai railway authority's associated operators are less aware of safety, fail to perform their duties seriously and correctly after a failure of equipment, and fail to address the problem in a way that is not likely to avoid accidents or mitigate losses。
In the course of accident rescue and rescue, the ministry of railways and the shanghai railways have had negative social consequences due to mishandling, late dissemination of information and inaccurate responses to social concerns。
SummaryLessons learned
Minister of railways: i'm sorry for the party and the people
On the morning of 28 december, the standing committee of the state council took a decision on the handling of particularly major railway traffic accidents on the “7-23” hot line. In the afternoon of the same day, the railway section held a conference of party groups and a national television teleconference on the railway system. It called on the staff of the national railway system to follow up with determination on the decisions of the standing committee of the state council, to ensure accountability, draw lessons from accidents, effectively strengthen security management, maintain workforce stability and promote railway security。
The minister of railways said that the accident of “7. 23” had revealed that the ministry of railways had learned a great deal in terms of security development concepts, the performance of sectoral supervisory functions, the lack of security clearance of key equipment and the weak security management of the shanghai railway service, as well as the poor emergency disposal of field operators. In the face of the serious consequences and negative effects of the accident, i am deeply sorry to the country and to the people. The ministry of railways and i have made in-depth inspections to the state council, and once again, on behalf of the ministry of railways, express our deep condolences to the victims of the accident “23”, and to the families, injured persons and their families。
Seriously
Fifty-four responsible persons were disciplined by the party
Liu zhijun's primary responsibility is zhang sunlight
The meeting agreed on the treatment given by the accident investigation team to 54 responsible persons, including the ministry of railways, the communications and signals group, the communications and signals research design institute and the shanghai railways bureau。
The meeting decided to entrust the ministry of railways and the minister of railways, sing guangzu, with conducting in-depth inspections of the state council, respectively。
Determination of responsibility
The investigation found that the comunicable group, the railway department and the shanghai railways department had the following responsibilities in the incident。
There are serious problems with r & d and quality management of controlled products in the circular group and its subdivisions. The convergence group, which performs its duties as the general contractor for the integration of communication signals from the temperature line, does not follow up on the development of the relevant priority equipment, but is asked about the lack of oversight management. Without full knowledge of the development process and progress of the equipment upgrade platform of the ld1-t column control centre, the design facility agreed to initiate the development of the upgrade platform solely on the basis of an oral report from the head of the institute for autocontrol of trains (hereinafter referred to as "land control " ); the equipment development design of the control centre was poorly reviewed to ensure that the signal products provided met the fundamental requirements of "failure-led safety". The master design institute hastily developed the equipment for the lkd2-t1 column control centre, did not organize a formal r & d design team and the research and development work was poorly managed; the equipment development and development design process was poorly managed, there was no comprehensive evaluation of the equipment for the control centre, and no single-board failure testing was performed, and serious design defects could not be identified if the equipment for the control centre failed to achieve safety orientation。
The ministry of railways and its relevant directorates (institutions) do not have strict control over tenders for equipment, technical reviews and the use of upper roads. The ministry of railways carries out the construction of infrastructure procedures in an irregular, insensitive and one-sided manner, with insufficient emphasis on security and inadequate management of the integration of the passenger-line system; the relevant functional departments, such as the transport department and the division of science and technology, engage in multiple irregular operations, technical reviews, use of the upper lanes, etc., at the lkd2-t1 control centre, and carry out unsupported and irregular technical pre-reviews, agreeing to the use of the lkd2-t1 control centre equipment without field testing and trial。
The shanghai railway authority and its subdivisions have not been able to deal with the emergency. The shanghai railways agency has a weak safety base management system, implementation of emergency management regulations and operating standards, and inadequate monitoring and inspection of staff performance of duties and compliance with regulations; inadequate command and handling of personnel responsible for accident rescue and rescue; and irregularities in the handling of malfunctions by personnel involved in vehicle, electrical and industrial systems。
