Summary:
With the continuous maturity of high-speed railway quality and technology, the requirements for the standardization and production quality of high-speed rail engineering mixing stations are also getting higher and higher. A strict management system has been formed in the quality control of concrete for high-speed rail projects, and there are strict control measures for the procurement and use of raw materials, especially after the powder is blown into the corresponding storage warehouse, it can only be used after passing the inspection. In addition to relying on a strict system, it is also necessary to have corresponding management methods, and the powder soot blowing supervision system of the mixing station can effectively prevent the powder from being used before inspection.
Key words: high-speed railway, soot blowing supervision system, powder is used before inspection.
The powder soot blowing supervision system of the mixing station is to complete the collection of soot blowing data through the soot blowing collection client with the soot blowing collection system, the collection software collects the soot blowing situation of the powder tank through the sensor installed in the external powder silo, and transmits the record to the soot blowing collection data platform, the tester fills in the relevant testing information in the data collection platform after passing the test and submits the application request, and the supervisor confirms the approval and unlocking, and the powder silo can be unloaded for concrete production after unlocking, so as to prevent the powder from being used before inspection. The intelligent soot blowing supervision system of powder in the mixing station is mainly composed of the following five parts.
1) The soot blowing detection sensor can sense whether the bulk powder transport truck blows soot to the powder silo of the mixing plant, and the soot blowing pipe of each powder silo is installed with one of this equipment.
2) The soot blowing detection center processor receives the soot blowing information collected by the sensors of all powder silos in the whole production line, sorts out, analyzes and summarizes, and then transmits it to the mixing station control computer through Ethernet communication.
3) The powder silo supervision system allows the information of the central processor to display the inventory information of all powder silos through the interface, which can use inventory, early warning inventory, blend inventory, provide powder warehouse inventory function, and also realize information interaction with cloud services.
4) The functions of the mobile client are: view the alarm information before inspection, view the soot blowing record of the powder silo, the tester initiates the batch inspection application, the supervision review and approval, the batch inspection application initiated by the tester, the material staff initiates the inventory inventory application, the supervision review and approval, and the cloud server for information interaction.
5) The office computer browser can complete the functions that can be completed by the powder silo supervision system and mobile phone software, and the recorded information is more intuitive and clear at a glance, and the query function is more abundant (Figure 1).
2.1. Personnel operation process.
1) Personnel with relevant authority, the main responsibility is to inquire about information, log in to the office computer (computer) or mixing station computer browser software or mobile phone software. Workflow: Check the soot blowing feed record of the powder silo, check the record of the powder bin before inspection, check the inventory record, check the inventory information of the powder silo, and then use the inventory, early warning inventory, and blending inventory to view the system's own alarm records.
2) The main responsibilities of the tester are to apply for batch inspection and log in to the office computer browser or mobile phone software (tester authority). Workflow: Check the soot blowing feed record of the powder bin A pair of powder batches that have been inspected and qualified, initiate a batch inspection application and wait for the supervision to confirm, review, approve and approve, the batch of powder is qualified before it can be used for coagulation production.
3) The main responsibilities of the material clerk are the application for inventory in the powder warehouse, and the login to the office computer browser or mobile phone software (the authority of the material clerk). Workflow: After checking the actual inventory of the powder silo or checking the actual inventory, the inventory of the powder silo is applied for and the inventory is confirmed, reviewed and approved by the supervisor, and the inventory of the powder silo in the system software is changed to the inventory of the inventory requested.
4) The main responsibility of the supervisor is to review the application of the tester and the material clerk, and log in to the office computer browser or mobile phone software (supervision authority). Workflow: Review the batch inspection qualified application submitted by the tester - the application is approved, the application is confirmed, the review is not passed, the application is rejected - the inventory inventory application submitted by the material reviewer is the confirmation application that is approved, and the rejection application (Figure 2) is not approved
2.2. Interface application.
1) Inspection and unlocking status, enter the warehouse storage simulation display area of the powder silo supervision system of the mixing station, the inventory can be displayed through the intuitive histogram, the warehouse without soot blowing or the warehouse inventory that has been inspected and unlocked is displayed in green, and the powder bin that has been blown or the powder bin that has not been tested is displayed in red.
2) Inventory correction of the warehouse, when the inventory quantity collected in the system does not match the actual quantity, you can use the inventory function, and the record submission application after the actual quantity of the inventory needs to be confirmed and approved by the supervisor on the sootblowing system platform, and the inventory correction takes effect.
3) Early warning setting interface, that is, the silo has the remaining qualified powder inventory, and the use of each bin needs to be set when the subsequent soot blowing needs to be set, and the use of the minimum early warning amount when the powder consumed in the production of concrete is stopped, so as to prevent the excessive use of the system from generating unchecked records and alarms.
4) Data query interface, through the query interface, you can query the soot blowing time, inspection records, uninspected records, inventory records and other related information (Figure 3).
The soot blowing collection client is mainly to cooperate with the soot blowing collection system to complete the collection of soot blowing data, and the collection software collects the soot blowing situation of the powder silo through the sensor installed with the external powder silo, and sorts out, analyzes and summarizes the records, and then transmits them to the mixing station control computer data platform through Ethernet communication. Sootblowing record includes a lot of powder details, when the powder silo is powdered soot blowing, the control computer data platform forms a detailed record of the time from the beginning of soot blowing to the end of soot blowing, the record is divided into the powder to be applied for without inspection and the application for unlocking status is divided into color markers, the powder that has been inspected and is being applied for is recorded as a blue mark, and the powder record that has been inspected and approved is a green mark. After the test results are qualified, the tester needs to fill in the relevant specific information of the inspection, and submit an application for unlocking, upload it to the supervisor to confirm the approval of unlocking, and the operator of the mixing station can judge the inspection status and unlocking of the powder according to the record color identification, and reasonably arrange the powder silo to produce concrete, so as to prevent the occurrence of the incident of powder being used before inspection. The powder soot blowing supervision system of the mixing station is a practical tool for the quality control of railway engineering concrete, and the front-line engineering quality control personnel must be willing to accept fresh and advanced technology, strengthen the learning and Xi maintenance of the soot blowing supervision system of the mixing station, and resolutely put an end to the use of powder without inspection, and prevent the use of unqualified powder into the engineering entity, so as to control the quality of railway engineering concrete.
Railway construction has always adhered to the principle of safety first.
First, quality first, the current railway safety and quality of ten red lines, is the bottom line, is absolutely insurmountable, powder has not been inspected before the use of a problem has become a difficult problem in the production of railway engineering concrete. The previous system has clarified the responsibilities and procedures, but it has not been able to completely regulate the problem of raw materials being used before inspection. The powder soot blowing supervision system of the mixing station has become the gatekeeper of the powder before the inspection, each batch of powder enters the site and begins to blow soot, and the powder soot blowing supervision system collects the powder soot blowing time from the beginning to the end through the sensor, and locks the powder storage bin during the inspection cycle, and fills in the inspection results by the tester after the powder inspection is qualified. Number and other specific information and apply to the test supervisor to unlock, the test supervision can be unlocked and used only after the client review and approval, and the material concrete material consumption is completely consumed in accordance with the production records of the mixing station, so that the problem of powder is not inspected and used first by the 4 gatekeeping procedures of "powder soot blowing supervision system, a tester, a supervisor, and a material consumption". If these 4 procedures are not followed in the production process of the concrete in the mixing station, the powder tank will not be unlocked, and a red alarm will be generated to alert immediately. The powder soot blowing supervision system of railway mixing station can strictly control the occurrence of powder before inspection, prevent unqualified powder from being used in engineering concrete, adhere to the ten red lines of railway safety and quality, and escort the quality of railway concrete.
Centennial plan, quality first, strictly abide by the ten red lines of railway safety and quality, and the railway mixing station powder soot blowing supervision system is another improvement of information construction. The powder soot blowing system of the mixing station has become an important tool for strategic planning of concrete quality control of railway engineering, which makes the concrete production of the mixing station more standardized and standardized, and is also an effective means to avoid the risk of powder being used before inspection. With the progress of railway engineering science and technology, the powder soot blowing supervision system of the railway mixing station needs to be further improved in the future, and there is still room for research in the connection and collection of powder transportation vehicles entering the site for weighing, empty car peeling, etc. In the future, the informatization of railway engineering construction will be more perfect, with more practical application significance, and effectively escort the construction quality of railway engineering.
