"If you want to do a good job, you must first sharpen your tools, and in order to make the work of the police at the front more efficient and convenient, I have to spend a lot of effort to create one 'secret weapon' for them. This is a passage written by Liao Yanxia, the second-level sergeant of the Information Center of the Jingyan County Public Security Bureau in Leshan City, on the title page of the workbook.
Liao Yanxia
Keep it in mind, see it in action. Liao Yanxia, female, after graduating from the police academy in 2005 to participate in public security work, she started from "zero" from a non-technical person into a "female sapper" in the field of informatization, responsible for the science and technology to strengthen the police innovation project four times won the Sichuan Provincial Public Security Organ Grassroots Technology Innovation Award, with science and technology to empower the police, with information services to practice, with data to protect safety, in the name of youth interpretation of the "Tibetan blue" responsibility.
In the past 19 years as a police officer, Liao Yanxia has been awarded 1 second-class merit, 2 third-class merits, and 3 personal awards. On the morning of April 28, the 2024 Sichuan Provincial Conference to celebrate the "May Day" International Labor Day was held in Chengdu, at which Liao Yanxia was awarded the "Sichuan May Day Labor Medal".
Cultivating ingenuity She is a grassroots science and technology expert
On the public security science and technology front, there is no sword shadow to investigate and solve cases, nor is there the thrilling thrill of arresting crimes, and some are just silently working day after day to empower the grassroots to fight.
In 2018, Liao Yanxia was transferred to the Intelligence Center of the Jingyan County Public Security Bureau and engaged in science and information work part-time. As a "little white" who is neither from a professional background nor has relevant work experience, the new unknown field makes Liao Yanxia feel unprecedented pressure. But at the same time, she is well aware that strengthening the police with science and technology is the future trend of the development of public security in the new era. "Only by gnawing this hard bone can we serve all police types well. She turned pressure into motivation, started from "zero" and went against the grain, forgot to sleep and eat after work, made a list of studies step by step, asked for advice "cheekily", and searched for information on the Internet, with the courage, resilience and sense of responsibility in her bones, she quickly mastered the professional knowledge of the network, data, computers, etc., and gradually grew into an "expert" in the public security department.
In mid-February 2019, Jingyan police received a notice that Feng, who was suspected of murder, might have fled to Jingyan. In order to capture Feng, the local police deployed while checking Skynet, and the police watched the surveillance day and night, and it took nearly two days to find clues.
"This kind of search is like looking for a needle in a haystack, wasting too much police force and energy, can you use a photo to structure, you can find all the trajectories of a person?" Fast structured retrieval, which used to take hours or even days to look through videos to find case information, can now complete the locking of suspicious persons in as little as one minute. This not only gave Liao Yanxia great confidence in her work, but also made her see the importance of "technology" to empower the police.
Subsequently, Liao Yanxia found that Jingyan County not only has few locations and insufficient clarity, but also "dark under the lights" at night, because it cannot provide strong data support, resulting in many cases that cannot be tracked and the scene cannot be restored. She also took the task of accelerating the construction of the front-end perception source of public security as another difficult problem to overcome.
A systematic project should not be inferior to the trunk and branches. During that time, she overcame the physical discomfort of pregnancy, held up her big belly, conducted field investigations, visited everywhere, carried out research, formed the "Feasibility Report on the Construction of Public Security Front-end Perception Source", and reported to her superiors, and soon the project was approved. In the second month of maternity leave, she returned to work to carry out plan formulation, parameter inquiry, expert demonstration, bidding, map labeling, and on-site survey. During the limited construction period, Liao Yanxia worked with the construction team on site during the day to install the equipment, and worked overtime at night to control and debug the equipment in the central computer room, and finally completed the project construction in June 2022.
Since the construction of the image structured platform and perception source, it has provided more than 30,000 data supports for various police types in the county, studied and judged more than 1,200 pieces of data on various risks and hidden dangers, assisted in handling 980 cases of various cases, and assisted in the arrest of 320 people of various types, providing a strong information guarantee for public security investigation and social control.
Stick to the original intention She is a little expert in reform and innovation
"Only with responsibility and responsibility can we realize value, and value will be needed by families, units, and society. In her work, Liao Yanxia made every effort to collect the needs of her colleagues and convert them into technical language, so as to create convenience for the work of various police departments, not only to be a good "behind-the-scenes hero" for her comrades-in-arms, but also to use an innovative platform to make the work of Jingyan Public Security "like a tiger with wings".
In the face of the small coverage of 350 megabyte base stations in Jingyan County, the high cost of base station construction and the difficulty of financial funds, in order to solve the problem of difficult communication calls of provincial departments and municipal bureaus, she used the existing police communication terminal network to overcome 10 technical problems, realized the intercommunication between the police communication terminal and the 350 trillion intercom call point, developed a video consultation cluster communication system, and won the third prize of the 2020 Sichuan Provincial Public Security Grassroots Technology Innovation Competition and the second prize of the Sichuan Public Security Mobile Application Innovation Award.
In 2021, she successively overcame 6 technical problems and completed the R&D and design of smart police security screens in 4 months. "Smart police security screen" has five major functions: one-key alarm, command and dispatch, trajectory tracking, publicity and prevention, and emergency rescue, which can directly obtain on-site images through real-time video and wireless transmission functions, shorten the time and space distance between command decision-making and on-site disposal, realize visual command and refined scheduling, and make police handling more scientific and efficient.
Since its operation, the local elderly and children have been linked to more than 1,300 cases through the security screen one-click alarm 110, providing more than 200 copies of trajectory tracking, and promoting the construction of "safe well research" to a new level. In the 2021 Sichuan Provincial Public Security Grassroots Technology Innovation Competition, the smart police security smart screen stood out from 143 projects and won the third prize, and won the "Excellent Case" of the 4th Digital Sichuan Innovation Competition in 2023.
Previously, the auxiliary police did not have their own digital certificates, and they needed to use the "key" of the police to carry out their work, which had certain risks and hidden dangers. How to improve the daily work efficiency of the auxiliary police and avoid law enforcement risks, Liao Yanxia is determined to tailor and create a comprehensive police informatization platform exclusive to the auxiliary police. In 2022, she spent 6 months to overcome 15 technical problems and institutional barriers, and finally successfully developed an auxiliary police microservice system, which has 11 functions such as standard address collection, cross-provincial and cross-border flow in and out, and business collaboration, which has transformed the auxiliary police from "dependent follower" to "independent norms", greatly improved the sense of belonging and honor of the auxiliary police, and promoted the construction of the auxiliary police team.
Since the official application of the system, it has provided a total of 120 pieces of accurate early warning information for the Jingyan County Public Security Bureau, helped to detect 37 online fugitives, added, collected and maintained 53,000 pieces of basic information, an increase of 139.5% month-on-month, and changed 13,000 pieces of information for the public, serving the masses more actively and in a timely manner.
The system won the first prize in the 2023 Provincial Public Security Grassroots Technological Innovation Special Activity and Science and Technology Innovation Competition, and was promoted and operated throughout the province, which was well received.
She is a junior instructor of information operations
"A person is not strong, a group of people is strong, and only by cultivating more police officers who understand informatization can we truly promote the development of informatization policing. Liao Yanxia often said that informatization is only built and not equal to white construction. In order to improve the level of information application of the vast number of people's police, she volunteered to serve as an instructor of information application in the overall situation of Jingyan, and often went to the grassroots level to "pass on the scriptures and send treasures" to the front-line police, and promote new tactics and technologies for the application of information.
Liao Yanxia benchmarked the work of strengthening the police with science and technology, summarized and summarized, studied the application function of the information system, and edited a manual of "Jingyan County Information Construction Application Guide". The feedback from the police at the grassroots level is good, practical and easy to use, and you only need to follow the steps to get the results you need.
"Sister Liao often goes to the front line of the grassroots to 'pass on the scriptures and send treasures' for us, and promote the application of new tactics and technologies in the application of information. He Xiaoyuan, a police officer of the Jingyan County Public Security Bureau, said that not long ago, there was a "case of theft of cash by a merchant Tang" in the jurisdiction, and after on-site investigation, the available clues were almost broken, and how to solve the case? He Xiaoyuan used the technology he learned in Liao Yanxia's information application training class, and finally found clues through information cross-collision analysis, and finally succeeded in arresting the suspect Lan Moumou, and recovered the stolen cash for Tang in a timely manner.
She also recorded a number of information technology micro-courses, organized and carried out two global information business training every year, carried out "one-to-one" departmental training every Tuesday, and organized more than 50 trainings every year, explaining the application of information police technology for the police in simple terms. Learn and practice, master the means of informatization and application knowledge, and let informatization empower the grassroots, combat the grassroots, and serve the grassroots.
In September 2023, the Jingyan County Public Security Bureau will set up a special information center, and Liao Yanxia deserves to be the "head". She further strengthened and perfected the operation and management of the information network, formulated the internal plan for network and information security, established the information security leadership responsibility system of all departments in the overall situation, and built the public security network and information security system of Jingyan County as a whole, effectively protecting the normal operation of public security information and communication and the security of public security business data; at the same time, she saved more than 30 yuan in equipment operation and maintenance costs for the county bureau every year through the integration of scientific planning system.
Behind her unrelenting persistence is Liao Yanxia's many "debts" to her family. But she chose to give up the "small family" to take care of "everyone", perennial with computers and data as a companion, in the massive amount of information and data, countless times of research and judgment and comparison, she worked silently for various police science and technology services day after day, decision-making and command, investigation and solving to provide fresh, accurate and timely reference, and finally in exchange for the masses a satisfactory smile.
There is no waiting for the wonderful, only the brilliance of drying. Liao Yanxia is like a tireless "computer host", constantly "running and chasing dreams" in ordinary posts, with the realm of "success does not have to be in me", and with the responsibility of "success must have me", write the "navy blue" glory belonging to the women police.
