Problems solved by technology

[0004] The detection of TW A CS signals is mainly based on time-domain difference technology. Most of these methods have complex data processing, poor real-time performance, and high equipment costs. In order to determine whether the signal bit is "1" or "0", due to the rigor of the calculation, the interference signal will seriously affect the judgment result of the detected signal, so the original method is difficult to apply in our country

Embodiment Construction

[0053] The circuit structure block diagram of a poultry purchase wholesale market data acquisition system is as follows: figure 2 shown. Includes centralized collector and multiple data loggers. The centralized collector is composed of a signal sending terminal A, a signal receiving terminal B, a network interface module 2 , a keyboard display module 10 and a microcontroller module 1 . The data recorder is composed of a signal sending terminal A, a signal receiving terminal B, a screen module 7 and a microcontroller module 1 . The centralized controller communicates with the data logger using the power line. The main station is the computer management system located on the top layer, which is composed of routers and computers.

[0054] The hardware structures of the power line communication signal sending end A, signal receiving end B, microcontroller module 1 and power supply module 4 in the centralized collector and data logger are the same.

[0055] The signal sending ...

Abstract

The invention relates to a data collecting system for a poultry purchasing wholesale market. A data entry machine is arranged at each trading point on a trading site. A code of a customer name, a booth number, the code of a poultry name and other data are entered when entering. A data concentrating collector sorts and summaries the entry data of the data entry machines and contents that cannot bedisclosed are set by keyboard. The concentrating collector communicates with the data entry machines by using power lines, the concentrating collector is accessed Internet through network interface modules, and a portable computer and a hand-hold mobile device are used for understanding goods detailed information of various purchasing wholesale markets.

Description

(1) Technical field: [0001] The invention relates to a data acquisition system for a poultry purchase and wholesale market, which includes a centralized collector and various data recorders, and uses a power line communication method to send a wide pulse signal to a specific point where the cycle voltage of the power grid passes through 0 to generate a sudden change of current, so that the cycle of the power grid can carry information . The centralized collector receives the data collected by each data logger, and connects to the Internet through the network interface module integrated with the TCP / IP hardware protocol stack, so that computers and handheld mobile devices can be used to access the remote computer management system. (two) background technology: [0002] Current power line communication mainly refers to power line carrier communication and two-way power frequency communication. Power line carrier communication PLC uses the existing power line to transmit signa...
