Method for solving communication deadlock of I2C (Inter-Integrated Circuit) bus

The invention discloses a method for solving the communication deadlock of an I2C (Inter-Integrated Circuit) bus. The I2C bus comprises a serial data line (SDA) and a serial clock line (SCL); the I2C bus is provided with a host and at least one slave; the method for solving the communication deadlock of the I2C bus comprises a host-based implementation method, wherein the implementation method comprises the following steps of: (A) monitoring a working state of the I2C bus, wherein the I2C bus is in a deadlock state if the host cannot send detection information to the slave of the I2C bus; (B) when the I2C bus is in the deadlock state, resetting a host module, and controlling the SCL to generate a clock pulse signal so as to unlock the slave of the I2C in the deadlock state; and (C) after unlocking the slave, reinitializing the host module to enable the normal work of the communication of the I2C bus again. According to the method for solving the communication deadlock of the I2C bus provided by the invention, no additional circuits are added, no additional cost is increased, the method for solving the communication deadlock of the I2C bus is applicable to any slave, the problem of deadlock can be rapidly and accurately solved, and no adverse effect can be brought for the normal operation of equipment.

Method for producing steam exploded stalk binder-less artificial boards by alkali process

The invention belongs to the field of binder-less environment-friendly artificial board production, and particularly relates to a method for producing binder-less environment-friendly artificial boards by means of hot pressing with steam exploded stalks as raw materials. The method includes steps of chopping the stalks, dipping the chopped stalks into alkali solution and then taking out with water content controlled, performing a steam explosion process on the stalks to obtain steam exploded stalks, drying the steam exploded stalks until reaching a certain water content, and finally performing hot press molding. In the method, alkali lignin is dissolved out during high-temperature digesting of the alkali-process steam explosion, and is blown instantly to damage cell wall structures, so that active groups of three components in the raw materials are exposed fully. In the later hot press molding process, the lignin dissolved out is subjected to condensation reaction with polysaccharide and lignin of the raw materials at a high temperature so as to form a binding effect. By the method, binder-less binding of the stalks is realized, cost for adding binders is saved, processing and production lines are simplified, environmental pollution caused by synthetic resin binders is reduced, production cost is lowered, and a new effective way is provided for artificial board production.

Photovoltaic system for feeding three-phase current into a power grid

The invention relates to a photovoltaic system for feeding three-phase current to a power grid that includes several monophase or three-phase photovoltaic inverters that can be connected to the power grid at the output end and are each fitted with a disconnecting device at the output end. The system includes several photovoltaic generators that are connected to the input end of the photovoltaic inverters. A central control and monitoring unit is connected between the photovoltaic inverters and the power grid. The control and monitoring unit has a grid monitoring device at the feeding point to the grid to measure one or more grid parameters. At least one communication link is provided between the individual photovoltaic inverters or the individual disconnecting devices and the connected central control and monitoring unit such that the connecting devices can disconnect the individual photovoltaic inverters from the power grid by means of a control instruction signal of the communication link. The central control and monitoring unit includes a load unbalance recognition component and a load unbalance regulation component, wherein the regulation includes limiting the power variation between the individual phases to a predetermined value.

Composite sludge conditioner based on iron-containing sludge pyrolysis residue as well as preparation and application of composite sludge conditioner

The invention discloses a composite sludge conditioner based on iron-containing sludge pyrolysis residue as well as preparation and application of the composite sludge conditioner. The composite sludge conditioner contains the iron-containing sludge pyrolysis residue and an oxidant matched with the iron-containing sludge pyrolysis residue for use, wherein the iron-containing sludge pyrolysis residue is the pyrolysis residue prepared by the steps of dehydrating iron-containing sludge obtained from an advanced oxidation technique involved with an iron-containing element reagent so as to obtain an iron-containing mud cake, and carrying out pyrolysis on the iron-containing mud cake. Compared with the prior art, the composite sludge conditioner has the advantages that by utilizing an integral reutilization manner of a subsequent treatment processes of the mud cake of the iron-containing sludge and improving the specific reaction condition parameters in each subsequent treatment process step, the treatment problem of the mud cake at the tail end in an existing sludge treatment technique can be effectively solved, and the composite sludge conditioner formed by the mud cake of the iron-containing sludge for the deep dehydration of the sludge can be used as a sludge conditioner for circularly conditioning the sludge, so that the adequate utilization of resources can be realized.
