Abstract

The invention belongs to a high-efficiency energy-saving data transmission receiving system which comprises a power circuit (1) and a display alarm circuit (8), and is characterized in that a master control circuit (2) is arranged in the system; the master control circuit (2) consists of an MSP430F5438 microprocessor master control chip UC1 and crystal oscillators YC1 and YC2; a pin 11 of the MSP430F5438 microprocessor master control chip UC1 is connected with a 3V power supply in the power circuit 1, a resistor R1, one end of each of capacitors C6 and C7, and a pin 2 of an ASM117 voltage stabilizing chip UP2; a pin 13 of the MSP430F5438 microprocessor master control chip UC1 is connected with one ends of the crystal oscillator YC1 and a capacitor C1; a pin 14 of the MSP430F5438 microprocessor master control chip UC1 is connected with the other end of the crystal oscillator YC1 and one end of a capacitor C2; and the pins 25-32 of the MSP430F5438 microprocessor master control chip UC1 are respectively connected with pins 1 and 2 of relay interfaces CON1, CON2, CON3 and CON4 in an oil line switching control circuit (6). According to the system disclosed by the invention, the problems that a field power supply is absent or the power supply erection is difficult and expensive are solved, the data transmission is reliable, the efficiency is high, the maintenance amount is small, and the cost is low.

Description

technical field

[0001] The invention belongs to a data collection and transmission system, in particular to a high-efficiency energy-saving data transmission and reception system suitable for the field where the power system is weak and where it is difficult to lay cables. Background technique

[0002] In the field of liquid monitoring such as liquid level or flow, at present, municipal electricity is basically used for collection, and data transmission is carried out through wired cables. During the transmission process, the following phenomena are often encountered: First, there is often no power supply in the field, The erection of power supply is very expensive or very difficult; the second is that sometimes the wired cables laid are damaged by construction and need to be maintained and repaired. Both of the above two situations increase the cost of manpower and materials, and the failure rate is high, which affects the reliability of data transmission. Contents of the...
