Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and in particular to an integrated monitoring device for the operating status of chemical pipelines. Background Technology

[0002] Chemical pipelines are typically equipped with monitoring devices such as thermometers, pressure gauges, and flow meters to monitor the pipeline's operating status in real time, ensuring the normal operation of the process and eliminating potential safety hazards. Current intelligent and visualized factories can achieve remote real-time online monitoring. However, for old or upgraded pipelines, although the addition of monitoring devices provides monitoring functions, each monitoring device is relatively independent, and the values ​​can only be read manually on-site, which is inconvenient and makes it impossible to detect abnormalities in a timely manner. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an integrated monitoring device for the operating status of chemical pipelines, which integrates the signals of monitoring equipment on the pipeline, centrally displays and alarms them, and transmits them remotely.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an integrated monitoring device for the operating status of a chemical pipeline, including a controller housing, a microcontroller inside the controller housing, the monitoring device being electrically connected to the input terminal of the microcontroller, a wiring terminal for electrical connection on the rear side of the controller housing, and a touch screen on the front side of the controller housing, the touch screen being electrically connected to the microcontroller; the controller housing is fixedly mounted on the chemical pipeline.

[0005] Preferably, the bottom of the controller housing is provided with a mounting base, which is detachably connected to the base. The bottom surface of the base is a concave arc structure for fitting against the outer wall of the pipe. A metal strip passes through the base to bind the base to the pipe.

[0006] Preferably, the mounting bracket is connected to the base by screws.

[0007] Preferably, the end of the metal strip is provided with a fixing plate, and the two fixing plates are connected and tightened by bolts.

[0008] Preferably, a buzzer is provided on the rear side of the controller housing, and an indicator light is provided on the top of the controller housing. The buzzer and indicator light are electrically connected to the output terminal of the microcontroller. There are two indicator lights 10, one for normal operation and the other for abnormal operation.

[0009] Preferably, the microcontroller is also connected to the host computer via an RS485 communication module, and a communication interface is provided on the rear side of the controller housing.

[0010] Preferably, a rubber pad is provided on the inner side of the metal strip.

[0011] Preferably, the monitoring device includes a thermometer, a pressure gauge, and a flow meter installed on the pipeline.

[0012] This utility model provides an integrated monitoring device for the operating status of chemical pipelines, which has the following beneficial effects: 1. Achieve integrated monitoring data to reduce reliance on manual operations. The device centrally connects to monitoring equipment such as thermometers, pressure gauges, and flow meters on the pipeline via a microcontroller, avoiding the inconvenience of traditional monitoring where each device is relatively independent and requires manual on-site reading of values. Simultaneously, the touchscreen display on the front of the controller housing visually presents all monitoring data, eliminating the need for on-site personnel to repeatedly check multiple dispersed devices, significantly reducing manual operation costs and improving data reading efficiency.

[0013] 2. Achieve timely early warning of anomalies and effectively avoid potential safety hazards. The device features a buzzer on the rear of the controller housing and two indicator lights on the top: a normal indicator and an abnormal indicator. Both the buzzer and indicator lights are electrically connected to the microcontroller's output. When the microcontroller detects that monitored data such as temperature, pressure, and flow rate exceed the preset normal range, it immediately triggers the buzzer alarm and illuminates the abnormal indicator light. This solves the problem of traditional decentralized monitoring failing to detect anomalies in a timely manner, allowing for immediate alerts to staff to address risks and preventing safety accidents caused by delayed processing of abnormal data.

[0014] 3. Supports remote monitoring functions to meet the needs of smart factory management. The microcontroller connects to the host computer via an RS485 communication module, and a communication interface is located on the rear of the controller housing, enabling the real-time monitoring data of pipeline operation to be transmitted to the host computer system. This design allows old or modified pipelines to be integrated into the remote management system of a smart, visualized factory. Staff can monitor the pipeline's operating status in real time from the backend without on-site supervision, breaking the spatial limitations of traditional on-site monitoring and improving the overall intelligent management level of the production process.

[0015] 4. Flexible and adaptable installation structure reduces the difficulty and cost of pipeline modification. The device features a mounting base at the bottom of the controller housing, which is detachably connected to the base. The base has a concave arc surface that fits snugly against the outer wall of the pipe. A metal strip passes through the base and secures it to the pipe, with a rubber pad on the inside of the strip. This structure allows for stable installation of the device without complex modifications to older pipelines, and it is adaptable to various specifications of chemical pipelines, significantly reducing the difficulty and cost of upgrading pipeline monitoring systems.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the rear structure of the present invention; Figure 3 This is a side view of the structure of this utility model; Figure 4 This is a structural block diagram of the control system of this utility model. Detailed Implementation

[0017] like Figure 1-2 As shown, an integrated monitoring device for the operating status of a chemical pipeline includes a controller housing 1, within which a microcontroller is housed. The monitoring device is electrically connected to the input terminal of the microcontroller. A wiring terminal 2 for electrical connection is located on the rear side of the controller housing 1, and a touch screen display 3 is located on the front side of the controller housing 1, electrically connected to the microcontroller. The controller housing 1 is fixedly mounted on the chemical pipeline. The microcontroller can be an industrial-grade model, such as the STM32F103 series, which has multiple analog and digital input interfaces, can simultaneously receive signals from thermometers, pressure gauges, and flow meters, supports 4-20mA standard industrial signals or RS485 digital signals, and can withstand operating temperatures from -40℃ to 85℃, adapting to the high-temperature, dusty environment of chemical workshops.

[0018] Preferably, the bottom of the controller housing 1 is provided with a mounting base 4, which is detachably connected to the base 5. The bottom surface of the base 5 is a concave arc structure for fitting against the outer wall of the pipe. The metal strip 6 passes through the base 5 and binds the base 5 to the pipe.

[0019] Preferably, the mounting base 4 is connected to the base 5 by screws 7.

[0020] Preferably, the end of the metal strip 6 is provided with a fixing plate 8, and the two fixing plates 8 are connected and tightened by bolts 9.

[0021] Preferably, a buzzer 11 is provided on the rear side of the controller housing 1, and an indicator light 10 is provided on the top of the controller housing 1. The buzzer 11 and the indicator light 10 are electrically connected to the output terminal of the microcontroller. There are two indicator lights 10, one for normal operation and the other for abnormal operation.

[0022] Preferably, the microcontroller is also connected to the host computer via an RS485 communication module, and a communication interface 12 is provided on the rear side of the controller housing 1.

[0023] Preferred, such as Figure 3 As shown, a rubber pad 13 is provided on the inner side of the metal strip 6.

[0024] Preferably, the monitoring device includes a thermometer, a pressure gauge, and a flow meter installed on the pipeline. The thermometer installed on the pipeline is a platinum resistance thermometer with a measurement range of -20℃ to 300℃ and an accuracy of ±0.5℃, meeting the temperature monitoring requirements of chemical media. The pressure gauge is a diaphragm pressure transmitter with a range of 0~10MPa and an IP65 protection rating to prevent media corrosion of the sensor. The flow meter is an electromagnetic flow meter or a vortex flow meter, matched to the pipe's inner diameter to ensure a flow measurement error ≤1%.

[0025] like Figure 4 The diagram shown is a block diagram of the control system. Thermometers, pressure gauges, and flow meters collect real-time data on the temperature, pressure, and flow rate of the medium in the pipeline and transmit the data to the microcontroller via signal cables. The microcontroller performs AD conversion on the input analog signals or directly receives digital signals and converts the data into a readable numerical format.

[0026] The microcontroller sends the processed real-time data to the touch screen, which displays the data in both numerical and graphical formats (such as a curve showing the data changes over the past hour), allowing on-site staff to view it intuitively. At the same time, the microcontroller has a built-in storage module that automatically stores historical data, and staff can query historical data for any time period through the touch screen for trend analysis.

[0027] The microcontroller transmits real-time data and alarm information to the host computer via the RS485 communication module. After receiving the data, the host computer software displays the monitoring data of multiple devices on the interface, supports data export and report generation, and realizes unified management of the operating status of multiple pipelines.

[0028] When in use, if the microcontroller detects that a certain monitoring parameter exceeds the preset alarm threshold, it immediately triggers a dual early warning mechanism: first, it controls the abnormal indicator light to change from off to constantly on, and second, it starts the buzzer to continuously alarm; at the same time, the touch screen will pop up an abnormal prompt window, clearly indicating the name of the abnormal parameter, the current value and the alarm threshold, so that staff can quickly locate the problem.

[0029] After an alarm is detected, on-site staff can view the historical trend of abnormal parameters on the touch screen to help determine the cause of the abnormality. After the fault is resolved and the parameters return to the normal range, staff can click the "Alarm Reset" button on the touch screen. The buzzer will stop, the abnormal indicator light will turn off, and the device will return to normal monitoring status. If a remote reset is required, a reset command can also be sent through the host computer software.

[0030] This utility model addresses the problem that monitoring devices such as thermometers, pressure meters, and flow meters on old or upgraded chemical pipelines are relatively independent, requiring manual on-site reading and failing to detect anomalies in a timely manner. It solves this problem by installing a microcontroller inside a controller housing fixed to the chemical pipeline. This microcontroller centrally receives signals from various monitoring devices and displays them on a front touchscreen display. Combined with a rear buzzer and dual indicator lights on the top, it provides timely warnings of anomalies. The system employs a base with a concave arc surface and a metal strap with rubber pads on the inside to secure the pipeline. The mounting base and base are detachably connected to accommodate different pipeline specifications without complex modifications. Furthermore, it connects to a host computer via an RS485 communication module for remote data transmission. Ultimately, this achieves integrated monitoring of the chemical pipeline's operating status, convenient installation, timely warnings, and remote management.

[0031] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
