Digital standard laboratory is generally a kind of fuel intelligent products, such as Bosheng Technology, which provides fuel intelligent products for five major power generation groups. Its digital standard laboratory products only participate in a part of the whole management process. But the significance of its existence can not be ignored. (1) Laboratory environmental management: monitor the abnormal changes of laboratory lighting, lighting, ventilation, temperature, humidity, cleanliness, electromagnetic interference, shock vibration, harmful gases and other environmental facilities through field equipment data collection or environmental information recording, and remind managers to pre-control abnormal data in time. (2) Laboratory quality control: carry out quality control procedures according to the requirements of national standards, and manage the process of laboratory quality control procedures, mainly including: regular maintenance and repair records of various laboratory equipment; Take coal samples from the warehouse every month to participate in the inter-laboratory comparison experiment records, and repeatedly measure or calibrate the indexes such as calorific value determination, total moisture determination, total sulfur determination and ash determination of coal; Verify the equipment according to the verification cycle of the laboratory equipment cycle; Calibrate the reference materials of various laboratory equipment according to their respective periods; Calibrate the equipment according to the equipment calibration cycle and record the test situation; The system automatically reminds relevant personnel to carry out various procedures, automatically records the test data, and enters the laboratory equipment account. (3) Sampling inspection management: automatically or manually input the data of sampling registration, weighing and other links into the system, compare the type, granularity, quantity, weight and time of the received samples with the records of sample preparation, and report to the police if any abnormality is found. (4) Monitoring of test process: the instrument parameters of different test items, such as constant temperature, constant temperature time, heating time, compensation temperature value, test interval time, inspection drying time and times, are solidified into the system. If it exceeds or falls below this temperature and time range, the system will be locked. The system can also include ambient temperature and humidity, and calibrate standard coal samples in a limited range this month. Laboratory work should be recorded in real time, and supplementary records are not allowed after the data is generated and confirmed. (5) Internal audit of test results: The system realizes the automatic generation of test reports, the comparison of test results with historical data, and the comparison of calorific value, total moisture, ash, sulfur and volatile matter of coal samples. Automatically judge the data of various test items of the same coal sample, and the internal audit procedure is at least two levels. The audited data can be sent to relevant systems as required. (6) Sample storage and inspection management: the sample storage room is equipped with customized electronic sample storage cabinets, and the sample storage cabinets are numbered according to the system requirements, and the corresponding cabinet doors are opened according to the system instructions. The activities of personnel who access and adjust samples are carried out by scanning and code brushing, and items such as granularity, weight and storage time of stored samples can be recorded. The status of the sample storage cabinet is displayed graphically. When the sample reaches the storage period, the system will save the sample destruction proposal and send it to the corresponding personnel. (7) Balance data management: When the samples involved in various tests are weighed several times before and after, the electronic balance can be connected to the computer to judge the correctness of the data according to national standards, and then the weighing data can be directly transmitted to the system. (8) Abnormal management of laboratory testing: If parallel sample testing is not carried out, the control points such as interval time and instrument temperature required for various tests are not up to standard, and the requirements for repeatability and reproducibility of various tests in the national standard are not met, the data will be invalid, and the system will automatically lock the program and give a voice prompt or alarm, and the system will automatically form a daily abnormal report of laboratory testing and send it to the designated personnel.
