High-efficiency energy-saving data transmitting and receiving system

Abstract

The invention relates to a high-efficiency energy-saving data transmitting and receiving system, which comprises a power supply circuit (1), a receiving frequency and transceiving interval setting circuit (3), a program downloading and updating circuit (9) and a display alarm circuit (8), and the high-efficiency energy-saving data transmitting and receiving system is characterized in that a main control circuit (2) is arranged in the system; the main control circuit (2) is composed of an MSP430F5438 micro-processor main control chip UC1 and crystal oscillators YC1 and YC2; the pin 11 of the MSP430F5438 micro-processor main control chip UC1 is connected to a 3V power supply, a resistor R1, one ends of capacitors C6 and C7 and the pin 2 of an ASM117 voltage-stabilizing chip UP2 in the power supply circuit (1); the pin 13 of the MSP430F5438 micro-processor main control chip UC1 is connected to one ends of the crystal oscillator YC1 and a capacitor C1; and the pin 14 of the MSP430F5438 micro-processor main control chip UC1 is connected to the other end of the crystal oscillator YC1 and one end of a capacitor C2. By means of the high-efficiency energy-saving data transmitting and receiving system, the problem that a power supply is not available in the wild or the power supply is erected difficultly at high cost can be solved; and the high-efficiency energy-saving data transmitting and receiving system disclosed by the invention is reliable in data transmission, high in efficiency, little in maintenance amount and low in cost.

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...
