A process hazard analysis (PHA) is performed in a data processing system. A chemical process to be evaluated is selected, after which a study type to be performed on the chemical process is also selected. The study type is conducted to evaluate the chemical process for the presence of hazard scenarios and any associated deficiencies requiring recommendations. After conducting the study, resolution plans to address the recommendations are generated. The study type used in the analysis may be customized or may be a known study type. The study type may use a risk matrix to generate a risk ranking for the hazard scenario. The risk matrix used may be created by the user, or may be a known risk matrix from another study type. After a resolution plan is generated, a resolution database may also be generated.

The invention discloses a tire state monitoring method based on study-type multiple perception and a device. The tire state monitoring method comprises the steps that the minimum mileage of one or a plurality of automobiles serves as an analysis unit, data are collected from an automobile bus, ABS pulse data of coaxial tires are modified and accumulated correspondingly according to correction value obtained under a study mode; if a sum of the ABS pulse data of diagonal tires is abnormal in the process, completeness of the monitoring cycle is ensured by replacing or filling; the ABS pulse independent accumulation data of the four tires obtained in the study mode after the correction values are corrected serve as a comparing object, and the real-time tire pressure values of the four tires serve as standard, and the accurate tire pressure values of the tires of the next cycle is calculated by looking-up a table; and pre-warning and alarming quantitative processing of the tire health stateare conducted, and data outputting, state displaying and sound-light alarming processing are conducted. The invention further provides a tire monitoring device. The tire state monitoring method can monitor multi-information of the tires, and a user can obtain comprehensive tire state information.

The invention discloses a multifunctional table equipped with a reading device by raising the table top with safety guards structure and various moderating assembled layout which can adjust and move the top movable table surface in longitudinal direction; the table can provides reading function on the book height, book apparent distance and angle corresponding with the ergonomics principle and scientific eye using state, and can solve the operating paradox and space paradox caused by several studying types proceeded at the same time, and also can induce and promote the user keep the optimum sitting posture of raising head and stiffing chest, and is convenient for users to change and moderate benefit setting posture, which can solve the shortcomings of the current table which force users incline their body and damage the eyesight and results in the stooping figure of hump back and fatigue, backache, and rachiopathy, and other pains and disease thoroughly and is favorable to increase the interest and effectiveness of the user and protect health.

The invention relates to a multifunctional experiment table for chemistry teaching, which comprises a table top and supporting legs, wherein a cylindrical experiment functional island is penetrated and fixed in the table top, a water tank is arranged on the table top at one side of the cylindrical experiment functional island, and the cylindrical experiment functional island is equipped with special experimental equipment satisfying the requirements for water, electricity, wind, gas, light and the like used for physical, chemical and biological experiments in middle schools. The invention overcomes the defect that an ordinary experiment table for teaching in the prior art only can satisfy the requirement of experimental operation in a single field and can not satisfy the requirement of discussing and studying type digital teaching; through the design, a computer can be placed on the table top, the special experimental equipment for physics, chemistry and biology can be intensively arranged in the cylindrical experiment functional island, the multifunctional experiment table has the advantages of simple structure and convenient assembly, the utilization ratio of a laboratory is also greatly improved, the investment of education cost is greatly lowered, and not only the experimental requirement of digital teaching is satisfied, but also a promoting action is performed for the universality of laboratory functions in the middle schools and the upgrading of laboratory functions in the future.

The invention discloses a study type COD online analyzer which comprises an embedded microcomputer system, wherein the embedded microcomputer system is connected to a singlechip microcomputer system,the singlechip microcomputer system is successively connected to a spectrum scanning stepping motor, a measuring valve and a cleaning valve, the measuring valve and the cleaning valve communicate to acirculating measuring tank, the circulating measuring tank is connected to an automatic cleaning device, the cleaning valve communicates to a clean water inlet through a pipeline, the measuring valvecommunicates to a tested water sample inlet through a pipeline, and the singlechip microcomputer system is connected to a photovoltaic conversion circuit. The study type COD online analyzer which ishigh in precision, high in measuring speed and free of pollution adopts a theory of ultraviolet spectrophotometry, and meanwhile, adopts a potassium dichromate oxidization method to measure the COD content in a water body, so that the problem that a lot of chemical reagents are used in the measuring process can be solved, the deteriorating consequence on the environment caused by secondary pollution is alleviated, and the pollution discharge monitoring effectivenss and safety are improved.

The invention relates to a self-electricity-generating study-type tellurion device. For the self-electricity-generating study-type tellurion device, a zinc-copper reaction electricity generating device is mounted on a base of a tellurion main body, and is connected with white-light LED lamps, a voice-control module single chip microcomputer provided with a storage battery, a red-light LED lamp, a yellow-light LED lamp and a trigger switch, wherein a microphone is mounted at the upper end of the tellurion main body, voice recording the names of the countries and the corresponding continents on the tellurion is stored in the voice-control module single chip microcomputer provided with the storage battery, if the trigger switch is touched, the red-light LED lamp and the yellow-light LED lamp simultaneously emit light, then the microphone can broadcast the name of the country of the corresponding continent in the area touched by a user, and therefore, the sound and light integrated fun study purpose is realized.
