Single chip microcomputer and peripheral circuit

Single chip microcomputer and peripheral circuit

The picture shows the MCU and peripheral circuit. The MCU selects AT89C55 of ATMEL Company and has 20K bytes of program memory inside. It is the control core of the whole fault detection circuit. It runs the program control detection circuit for voltage detection, and the test results are preliminary. Processing, generating a unit-level fault table, and sending it to the superior for comprehensive processing. The integrated circuit D2 (MAX813) is a watchdog. The main function is to monitor the running status of the MCU program. If the program runs for more than 1.6 seconds, the watchdog will generate a reset signal to reset the MCU and make the program re-enter the normal steps. The integrated circuit D3 (MAX485) is an RS-485 serial communication interface, which realizes mutual conversion between TTL level and RS-485 level, and is a communication interface between the detection circuit and the upper unit. Diode V2 is the fault indicator that illuminates when a power failure is detected.

2.3 After fermentation Orange (Orange made enzyme solution navel orange), seized after the hand, breaking and other processes made of navel orange sauce.

Effects: lung, spleen shun gas, without any food additives, preservatives, is the first choice of children and senior citizens.

Companies registered capital of 35 million yuan, the end of 2014 the total assets of 48.69 million yuan, including fixed assets of 37.52 million yuan. The company's existing cooperation Orange cultivation base 7043.5 acres, the company production base is located in Jiangxi County Tech Industrial Park Chu Tan industrial area, covers an area of 120 acres, it has built a standard plant 9,000 square meters, Nissan 6000 kg Orange enzymes and other liquid enzyme products. Enzyme, known as enzyme, refers to a polymer substance having biocatalytic functionality. In the catalytic reaction system an enzyme, the reactant molecules are known as substrates, enzyme substrates by catalytic conversion to another molecule. Almost all cellular activity of enzymes involved in the process are required to improve efficiency. Similar to other non-biological catalysts, enzymes chemical reactions by lowering the activation energy to accelerate the rate of the reaction, most of the enzyme catalyzed reaction rate can be increased a million times; in fact, the enzyme is to provide an activation energy needs than another low way, so that more particles to have less than the activation energy of the reaction kinetic energy, thus speeding up the reaction rate. Enzyme as a catalyst, in itself is not consumed during the reaction, it does not affect the chemical equilibrium reactions. Positive enzyme catalysis, but also a negative catalytic effect, not only to accelerate the reaction rate, but also to reduce the reaction rate. And other non-living catalysts is different, having a high degree of specificity of enzyme, only a catalytic reaction or produce a particular specific configuration.
