Abstract

The invention relates to a multipath data acquisition control module, which is a hardware system used for carrying out acquisition, transmission, data abnormal alarm and data display on data of a sensor. Data acquisition is a process of acquiring data from configured data acquisition equipment or a configured sensor by the system and storing the data to a database. Data transmission is a process of uploading the acquired data to a server through a serial port, an Ethernet port and a short message system. Alarm processing is the process that the system judges whether a current numerical value of each monitoring index is abnormal in real time during the process of data acquisition, if so, uploads a command to the server through the serial port and the Ethernet port for alarm or alarms through a short message module. A data display portion is used for displaying the acquired data on an LCD screen in real time.

Description

Multi-channel data acquisition control module

[technical field]

Multi-channel data acquisition control module of the present invention can carry out omnibearing monitoring management by various kinds of sensors to scene, unusual circumstance can be reported to the police, and guarantees the stability of system, reduces the burden of maintainer, improve the reliability of system, achieve the scientific management in monitoring place.Accomplish the real time implementation of supervisory system, intellectuality, networking, make user realize convenience, the management of reliable, accurate, unattended Centralized Monitoring.

[background technology]

The management in current many places (machine room, transformer station, base station, warehouse etc.) adopts timing personnel to patrol the mode of equipment, so not only can not understand visual plant ruuning situation in time, and when there is no professional equipment keeper, many places have to arrange the personnel being almost ignorant of plant maintenance on duty, and this is undoubtedly hidden trouble to the equipment safety operation in above-mentioned place.

For solving the problem, this invention is by gathering peripheral sensors, and when occurring abnormal by note or Ethernet, serial ports sends information to monitor staff, the accident of process warning in time.

[summary of the invention]

Technical scheme of the present invention is:

1, pick-up transducers 4-20mA current-mode analog quantity, switching value, sends single-chip microcomputer process to.

2, equipment sends data to server by Ethernet or serial ports, can be monitored in real time by server to equipment external sensor.

3, equipment is with SMS module warning function, when image data exceedes maximal value, warning message is sent to user.

4, the data collected also show by carrying liquid crystal display by equipment in real time, are reported to the police by hummer.

5, equipment exports and RS485 communication interface with seven way switch amounts, can gather having the sensor of 485 communication functions.
