Motor Vehicle Accident Investigation Report Has Still Not Completed

The EMU accident investigation report still has not completed the investigation team of the State Council for more than 200 meetings and formed nearly 2 million words of materials. There are problems in equipment and management. Problems such as technology and management need to be analyzed and verified. It will take some time for the report to form. The result will be announced in a timely manner by the State Council. -23. The investigation team of the particularly serious railway accident group on the Wenzhou-Wenzhou Railway reported the progress of the accident investigation on the 21st.

After the "7-23" Wenzhou-Wenzhou railway line suffered a particularly serious railway accident, the party Central Committee and the State Council attached great importance to it. In accordance with relevant national laws and regulations, the State Council approved in a timely manner the establishment and adjustment of the accident investigation team. The accident investigation team consists of a technical group, a management group, and an integrated group. It has appointed domestic experts to form an expert group and invited the Supreme People's Procuratorate to send personnel to participate. The investigation team earnestly implemented the spirit of decision-making, deployment and instruction of the Party Central Committee and the State Council. It adhered to the principles of scientific rigor, legal compliance, seeking truth from facts, and objectiveness and fairness, relying on expert support, relying on scientific methods, relying on factual evidence, and earnestly conducting serious investigations. Progressive progress. The previous day, the investigation team stated that it was a particularly serious liability accident that initially identified the cause of the existing equipment defects and malfunctions, as well as the inability to handle equipment and the safety management. This statement is basically the same as that described by the news spokesman of the State Administration of Work Safety at the end of August.

Focus Q What did the accident investigation team do? Site investigation, simulation experiments, etc. were carried out. Nearly two million words of various special reports and related written materials were formed. The investigation team conducted in-depth investigations, simulation tests, and techniques. Identification, investigation and evidence collection, comprehensive analysis and expert demonstration and a series of work:

Carried out the storage and protection of accident vehicle debris and other relevant physical data and data; retrieved and analyzed the recorded data before and after the accident, as well as all the information of the “black box”, the locomotive integrated wireless communication equipment and other devices, instruments, and equipment; and extracted the columns. Control center data, through the establishment of data platform to reproduce the equipment at the time of failure; the Yongjia station to the Wenzhou South Station between the temperature line on the scene of the accident vehicle simulation and reproduction test. At the same time, the investigation team successively conducted the insulation performance test of the Wenzhou South Station line and the wireless communication field strength detection of the Yongwen line.

The investigation team also commissioned the State Grid Electric Power Research Institute to use the nationwide lightning location monitoring system of the electric power system to statistically analyze the lightning activity data near the Wenzhou South Station at the time of the accident; and commissioned the China Electric Power Research Institute to conduct lightning impact on relevant electronic components. Fuse simulation test under current and power frequency current; commissioned authoritative experts from China Meteorological Administration to test and verify the lightning activity in the area where the accident occurred; commissioned the relevant evaluation agencies of the Ministry of Industry and Information Technology to form a test group and control center and acquisition drive board. Hardware and software were tested.

Up to now, the investigation team has held more than 200 meetings, including analysis meetings, demonstration meetings, seminars, etc., accessing nearly 1,300 relevant materials, surveying and talking about 300 people, forming various special investigation reports and related written materials. 2 million words.

In response to the problems exposed by the accident, the railway system organized and rectified in a timely manner to investigate and eliminate hidden dangers in the entire road.

Q. Why do the investigation reports take time? A. The technical and management issues need to be further analyzed and verified; the next step is to put forward opinions on the definition of responsibility. Due to the specialities of high-speed rail design, construction, operation, and management, the situation is more complicated. The links, areas, and scope involved in the investigation work require a lot of testing and verification. A lot of basic work has been done in the early stage, and important basic data and experimental data have been obtained. However, there are still many problems in technology, management, etc. that need further analysis and verification. The formation of accident investigation reports will still take some time. Next, the accident investigation team will continue to work hard in a scientific, rigorous and conscientious manner. It will do a solid job of investigating and collecting evidence in every aspect and will not miss any doubts. The investigation team will scientifically analyze and identify the technical causes of the accident, and trace the root causes to thoroughly investigate the source problems; thoroughly and thoroughly investigate the management reasons for design and development, testing and appraisal, review permission, on-board use, and transportation organization; Relevant responsibilities of relevant units and personnel are defined in accordance with the law, and opinions on handling are proposed. From the aspects of the legal system, mechanisms, standards and standards, traffic organization, and equipment and facilities, proposals are made to strengthen the safe production of railways and promote the healthy development of China's high-speed rail industry. The progress and results of the investigation on the accident will be announced to the public in a timely manner and consciously accept social supervision. According to Xinhua News Agency official response survey report time has not reached the "limit"

According to the provisions of the SAWS, according to regulations, the incident should be submitted within 60 days of the accident, but the special case can be extended up to 60 days. (Reporter Liu Chunrui) How long does it take to form a report from July 23 onwards? Yesterday, the relevant person in charge of the State Administration of Work Safety stated that for the investigation report, the State Council’s Decree No. 493 had a clear provision. However, it cannot be too absolute. It depends on the specific circumstances of the accident.

According to the introduction, according to the State Council's Decree No. 493, the accident investigation team shall submit an accident investigation report within 60 days from the date of the accident. Under special circumstances, the time limit for submitting the accident investigation report may be extended, but it may be prolonged after the approval of the people's government responsible for accident investigation. The maximum period of time is not more than 60 days. In the case of a particularly serious accident, the people's government responsible for the investigation of the accident shall make a reply within 30 days from the date of receipt of the accident investigation report. In special circumstances, the approval time may be appropriately extended, but the extension period may not exceed 30 days.

Judging from State Council Decree No. 493, the accident investigation team formed the accident investigation report within the specified time.

Who is responsible for handling accidents is divided into several categories? The above-mentioned person in charge pointed out that if he has violated the criminal law, he must be investigated for criminal responsibility. If he is not criminally responsible and he violates the relevant laws and regulations for production safety, he must be disciplined by party discipline. This should be analyzed in accordance with the responsibility of the person responsible for the accident, and it is closely related to the cause of the accident investigation. There will be no speeding.

Expert opinion "Device defects include signal systems"

A panel member believes that a lightning strike has caused problems in the signal system; the final investigation report needs to summarize five groups. Yesterday, Liu Lianguang, a member of the “7-23” extraordinary accident expert group and North China Electric Power University, stated that the State Council “7-23” Investigation Team The progress of the accident investigation announced on the 20th was only a preliminary result, in which the initial identification of the accident had equipment defects and the causes of the malfunction, so-called equipment defects, including defects in the design of the signal system.

"I am mainly responsible for the electrical system. This system has no problem in itself." Liu Lianguang said that the investigation team set up by the State Council is divided into five groups, including expert groups, management groups, and technical groups, while the expert group has another 12 individuals. Divided into three groups, responsible for electrical, signal, and dispatch. He said that the final investigation results and reports of the accident were summarized by the investigation team according to the five groups.

The investigation team stated that the initial identification of the accident was caused by equipment defects and failures. What does the equipment mean in the end? Professor Liu Lianguang said that there are many so-called devices, including signal systems, control systems, and so on. He affirmed the previous statement made by the investigation group of the State Council and the flaws in the signal system design. "The problem with the signal system, mainly caused by lightning strikes, has an impact on the signal," he stressed.

As early as mid-August, the investigation team of the State Council had initially completed the technical report on the accident and the report of the expert group on the direct cause of the accident. Huang Yi, a spokesperson for the State Administration of Work Safety, once said that through preliminary analysis, the accident revealed that the accident had exposed defects in the design of the signal system, which led to the problems caused by lightning strikes, and also reflected the inadequacy of emergency response and safety management after the occurrence of the malfunction. There are vulnerabilities.

However, the deputy head of the accident investigation expert group and the academician of the Chinese Academy of Engineering, Wang Mengshu, had previously revealed during an interview with this reporter that the expert group believed that there was no problem in the technology of the motor vehicle signal and it was a question of responsibility and management.

In response to this statement, Liu Lianguang said that Wang Mengshu’s so-called EMU signal technology is no problem, but on behalf of his personal point of view, it is not convenient to make comments. "He is an academician. That's his personal opinion."

The investigation of the accident investigation of motor vehicles On July 24, the original spokesman of the Ministry of Railways, Wang Yongping, told Xinhua News Agency reporters on the second day of the accident that the preliminary cause of the accident was "a lightning stroke caused equipment failure."

On July 28, An Lusheng, the director of the Shanghai Railway Bureau, said that the equipment quality, personnel quality, and on-site control issues reflected in the accident indicated that the safety foundation of the railway sector was still relatively weak. These problems reflected that the safety management of the railway sector was not in place.

August 4th Huang Yi, a spokesperson for the State Administration of Work Safety, said: “This is not a natural disaster. It is a particularly serious rail transport accident. Moreover, the railway also pointed out that the safety management leaks that were exposed during the accident. And problems."

August 22, spokesman of the State Administration of Work Safety, Huang Yi said that the accident not only revealed defects in the design of the signal system, but also reflected weaknesses in emergency response and safety management after the failure.
