CAN (Controller Area Network) bus remote monitoring system based on electric heat tracing liquid indicator

Abstract

The invention relates to a CAN (Controller Area Network) bus remote monitoring system based on an electric heat tracing liquid indicator. The CANbus remote monitoring system based on the electric heat tracing liquid indicator is technically characterized by comprising the electric heat tracing liquid indicator, a CAN bus and a remote monitoring center. The electric heat tracing liquid indicator comprises a sealing flange, an electronic control device, a connecting flange, a measuring cylinder, an electric heat tape, an insulating layer and a protective housing; the electronic control device comprise an MCU (Microprogrammed Control Unit) module, a power module, a measuring sensor, a temperature sensor, a CAN module, an audible and visual alarm module and an electric heat tape control module; the MCU module is respectively connected with the measuring sensor, the temperature sensor, the electric heat tape control module, an audible and visual alarm and the CAN module; the electric heat tape control module is connected with the electric heat tape; the CAN module is connected with the remote monitoring center through the CAN bus to realize a remote monitoring function. According to the CANbus remote monitoring system based on the electric heat tracing liquid indicator provided by the invention, the on-site liquid indicator is connected with the remote monitoring center throughthe CAN bus, so that remote monitoring personnel can remotely monitor the liquid indictor anytime anywhere, and the control mode is flexible and convenient.

Description

technical field [0001] The invention belongs to the technical field of liquid level gauges, in particular to a CAN bus remote monitoring system based on electric heat tracing liquid level gauges. Background technique [0002] At present, in the process of petroleum, chemical and other industrial production, the measured medium needs a certain temperature protection, especially in the northern winter when the outdoor temperature is very low, and the liquid level gauge must be insulated to ensure the temperature of the liquid level gauge when working outdoors. normal work. Existing heat-retaining liquid level gauges usually have a steam jacket type and a hot water heating type. In order to realize the above working methods, facilities such as boilers and pipelines must be installed, which greatly increases the production cost; in addition, the existing liquid level gauges usually Without remote monitoring function, it is impossible to know the liquid level of on-site equipmen...
