Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] figure 1 It is a schematic diagram of the CAN bus connection.

[0026] Such as figure 1 As shown, the host 1 has RJ45 or GPRS communication capability, and the data received on the CAN bus is sorted into a standard protocol and sent to the Internet network, and finally reaches the server 2, that is, the network cloud background. The temperature, humidity and environment sensor 3, the circulation sensor 5, the gas sensor 6, the zone sensor 7, the vibration optical cable sensor 9, etc. can send monitoring data to the CAN bus. The control module 10 on the device can send special control commands to control the opening of fan I, light II, dehumidifier III and alarm IV, realizing intelligent equipment management.

[0027] The host 1 can also transmit the data monitored by various modules to the information display subtitle machine 4 in real time th...

Abstract

The invention relates to electric power online monitoring equipment based on a CAN bus. According to the invention, a host has the RJ45 or GPRS communication capability, and can organize the received data into standard protocols through the CAN bus and transmit to the Internet to finally reach a server; and a temperature, humidity and environmental sensor, a circulation sensor, a gas sensor, a defense area sensor and a vibration cable sensor transmit monitoring data to the CAN bus, after reception and processing through the host, the server can be notified, and a control command can also be transmitted to a control module on the bus to control the switch-on of a fan, lighting, dehumidification and alarm, and the intelligent equipment management is achieved. According to the invention, by use of the communication bus, a safer and faster data acquisition and control method for the online equipment can be achieved through data acquisition and control based on the CAN bus, and the hot-swap access of acquisition equipment when the host is powered on is also achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power online monitoring, and relates to an online monitoring device, in particular to data communication and control between the online monitoring device and a sensing module or an execution module. Background technique [0002] The existing common electric power on-line monitoring equipment and the sensor module or execution module adopt the serial port communication mode. Since the serial port communication is one-to-one, in the face of various types of detection data and complex environments, an online monitoring host device needs to use a large number of serial port resources to access data from different sensors, and there are many limitations in communication as a host characteristics, unable to meet the rapid development of power equipment needs. Especially in the transmission of images with a large amount of data over overhead lines, the limitations are more obvious. Contents of the in...
