1. Project background
The “Highway Maintenance Management System Project” constructed by Zhejiang Expressway Information Engineering Technology Co., Ltd. is based on the maintenance plan of the expressway and based on the basic resource database. The maintenance business units at all levels of the construction unit are connected into a more efficient and scientific maintenance business unit. Realize the information management of the maintenance plan, basic data, maintenance process, engineering data, and maintenance equipment, and achieve the sharing of maintenance information and resources, so as to improve work efficiency and improve working conditions. The operation of the system relies on the timeliness and completeness of road section inspection information collection.
2. Customer demand survey
Through customer research, the inspection work of Zhejiang Expressway requires breakthroughs in the following aspects:
(1) Realize the electronic archiving of basic structure information such as bridges, tunnels, culverts, tunnels, and slopes for maintenance of basic data;
(2) Ensure that the staff inspect one by one according to the pre-set route, and ensure the quality of the inspection, and eliminate the situation of passive sabotage, patrol on behalf of, missed patrol or no patrol.
(3) The staff can take photos or videos of the on-site situation at the same time, combine the longitude and latitude information of the terminal equipment positioning and the information such as the height of the sensor on the terminal and send it back to the background for future analysis, so as to achieve potential dangers and need to be maintained in advance. Information can be predicted in advance.
(4) The operation will not be affected in harsh environments such as thunderstorms and high temperatures, especially requiring high-level waterproof and dustproof.
Three, solution description
Hardware terminal (A2000)
Android platform: Android 4.0 system, which can support the operation of customer’s personalized customized software.
Communication module: WCDMA+EVDO, providing all-round wireless support.
Camera: Support USB OTG camera.
Sensors: including gravity sensors, ambient light sensors, distance sensors, height sensors and electronic compasses, etc., which can collect various position data to ensure the integrity of the inspection information.
IP65 protection level: three-proof protection; after 1.5 meters of multiple drops.
Visual scheduling platform
1. Authority management: patrol personnel information management, role management, authority assignment.
2. Inspection task management: mainly includes manual formulation and automatic generation of inspection tasks, task assignment, inspection and completion inspection, etc.
3. Data exchange with handheld mobile terminals: equipment inspection standards, facility data, personnel conditions, task information and other information are downloaded to the handheld mobile terminal; and the handheld mobile terminal inspection results are returned to the system.
4. Comprehensive inquiry and statistical analysis of daily inspection results: Inquire about the in-place rate of inspections, and supervise the quality of inspections.
5. Basic data maintenance: Mainly realize the maintenance of basic data required by the system, such as: evaluation standard maintenance, inspection personnel maintenance, facility information maintenance, etc.
Mobile function
1. Basic data reception: Information such as equipment inspection standards, facility data, personnel conditions, and task information is downloaded from the application server to the handheld mobile terminal.
2. Prompt for patrol task: It can prompt the relevant data of the patrol task, and can query the basic information of the patrol object and prompt the current record information of the patrol object.
3. Facility inspection function: Through the identification of the radio frequency tag inspection point through the handheld mobile terminal, the inspection process is accurately recorded (including inspection time, inspection personnel, facilities, inspection items, existing problems, scoring, etc.) ).
4. Return inspection results: mainly return inspection results from the handheld mobile terminal to the background management system.
Fourth, the inspection business process
1. Log in with the inspector’s account and download the current inspection task assigned by the background management system and the automatically generated inspection result record table.
2. In accordance with the inspection tasks, perform functions such as inspection, scoring, problem recording, and problem shooting or video on the inspection points located by the system, and transmit the inspection results to the background system in real time through the 3G network.
3. Hold the mobile terminal to check whether the current inspection task has been completed. If there is any omission, the handheld mobile terminal will have an alarm sound and a dialog box prompt, and the final inspection result cannot be scored.
4. The handheld mobile terminal patrol operation system integrates the scoring results of each patrol point, evaluates the comprehensive score, and returns the host. This patrol is over.
Five, system advantages
Basically, the phenomenon that inspectors and inspected objects cannot be scientifically and accurately assessed and monitored, and timely and complete inspection information is transmitted back to the system background, effectively ensuring that the inspected facilities in the expressway service area are always in good condition.
