Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to a method and system for transmitting environmental monitoring data in enterprises. Background Technology

[0002] With increasingly stringent environmental protection requirements, monitoring enterprise production is imperative. Key polluting enterprises need to ensure the normal operation and data quality of automatic monitoring equipment by conducting comparative monitoring, regular verification and calibration, and other methods in accordance with standards and regulations, while also guaranteeing data transmission rate and data validity.

[0003] However, in actual operation, the CEMS equipment and the data acquisition and transmission instruments used are all network devices that operate 24 hours a day without interruption. It is necessary to ensure stability and security as much as possible, and to promptly switch to backup equipment in case of problems, and notify the on-duty personnel to immediately start the emergency procedure.

[0004] Taking the dynamic management and control of exhaust gas pollution sources in power plants as an example, conventional dynamic management and control systems achieve simultaneous monitoring of online detection equipment data, parameters, and status. Simultaneously, the network topology within the station building involves analyzers, flue gas parameter devices, and particulate matter devices directly connected to the dynamic management and control unit. The dynamic management and control unit then uploads data to the online monitoring equipment dynamic management and control platform via wired or wireless means. This network uses a serial connection; if the dynamic management and control unit malfunctions, the platform will lose data, and it cannot re-upload it. Summary of the Invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a method and system for transmitting enterprise environmental monitoring data to solve the above-mentioned technical problems.

[0006] In a first aspect, the present invention provides a method for transmitting enterprise environmental monitoring data, comprising a master dynamic controller and a slave dynamic controller, the method comprising:

[0007] The dynamic control unit monitors the operating status of the main dynamic control unit, which receives monitoring data from multiple devices and forwards the monitoring data to the online monitoring platform.

[0008] After confirming the fault of the main dynamic controller from the dynamic controller, the secondary dynamic controller takes over the work of forwarding the monitoring data of multiple devices to the online monitoring platform from the main dynamic controller;

[0009] The new main dynamic controller acquires the connection status with multiple devices and uploads the connection status of the new main dynamic controller with multiple devices to the online monitoring platform;

[0010] The new main dynamic controller sends a takeover prompt to the online monitoring platform, which triggers the online monitoring platform to generate a fault alarm for the main dynamic controller.

[0011] Furthermore, the monitoring of the operating status of the master dynamic controller by the slave dynamic controller includes:

[0012] Receive heartbeat signals periodically sent by the main dynamic controller from the dynamic controller.

[0013] Furthermore, the step of confirming a fault in the main dynamic control unit from the secondary dynamic control unit includes:

[0014] If the time elapsed between the current moment and the last time the heartbeat signal was received exceeds a preset threshold, the main dynamic controller is confirmed to be faulty.

[0015] Furthermore, the method also includes:

[0016] The dynamic control unit periodically receives monitoring data from multiple devices and forwards the received monitoring data as test data to the online monitoring platform. The test data serves as the standard for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the main dynamic control unit.

[0017] Furthermore, the method for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the main dynamic control instrument includes:

[0018] Compare the monitoring data uploaded by the main dynamic controller with the test data. If they match, the monitoring data uploaded by the main dynamic controller is considered accurate.

[0019] Furthermore, the online monitoring platform performs statistical analysis on the monitoring data, generates monitoring charts based on the monitoring data, and displays the monitoring charts.

[0020] Secondly, the present invention provides an enterprise environmental monitoring data transmission system, comprising a master dynamic controller and a slave dynamic controller, the system comprising:

[0021] The status monitoring unit is used to monitor the operating status of the main dynamic controller from the dynamic controller. The main dynamic controller receives monitoring data from multiple devices and forwards the monitoring data to the online monitoring platform.

[0022] The work takeover unit is used to confirm the failure of the main dynamic controller from the dynamic controller and switch from the dynamic controller to a new main dynamic controller to take over the work of the main dynamic controller in forwarding the monitoring data of multiple devices to the online monitoring platform.

[0023] The communication upload unit is used for the new main dynamic controller to obtain the connection status with multiple devices and upload the connection status of the new main dynamic controller with multiple devices to the online monitoring platform.

[0024] The alarm triggering unit is used to send a takeover prompt message to the online monitoring platform from the new main dynamic controller. The takeover prompt message triggers the online monitoring platform to generate a fault alarm for the main dynamic controller.

[0025] Furthermore, the monitoring of the operating status of the master dynamic controller by the slave dynamic controller includes:

[0026] Receive heartbeat signals periodically sent by the main dynamic controller from the dynamic controller.

[0027] Furthermore, the step of confirming a fault in the main dynamic control unit from the secondary dynamic control unit includes:

[0028] If the time elapsed between the current moment and the last time the heartbeat signal was received exceeds a preset threshold, the main dynamic controller is confirmed to be faulty.

[0029] Furthermore, the system also includes:

[0030] The status calibration unit is used to periodically receive monitoring data from multiple devices from the dynamic control instrument and forward the received monitoring data as test data to the online monitoring platform. The test data serves as the standard for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the main dynamic control instrument.

[0031] The beneficial effects of this invention are as follows:

[0032] The enterprise environmental monitoring data transmission method and system provided by this invention can quickly switch the monitoring data transmission work to the slave dynamic controller when the master dynamic controller fails, ensuring the integrity of online data. It can also upload the work switching information and the connection status with the monitoring equipment to the online monitoring platform, improving the reliability and stability of the system and meeting the high requirements of enterprises for data transmission integrity.

[0033] Furthermore, the design principle of this invention is reliable, the structure is simple, and it has a very wide range of application prospects. Attached Figure Description

[0037] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0038] Figure 1 This is a schematic flowchart illustrating a method according to an embodiment of the present invention. Wherein, Figure 1 The implementing entity can be an enterprise environmental monitoring data transmission system.

[0039] like Figure 1 As shown, the system includes a master dynamic controller and a slave dynamic controller. The method includes:

[0040] Step 110: Monitor the operating status of the main dynamic controller from the dynamic controller. The main dynamic controller receives monitoring data from multiple devices and forwards the monitoring data to the online monitoring platform.

[0041] Step 120: Confirm the fault of the main dynamic controller from the dynamic controller, and take over the work of forwarding the monitoring data of multiple devices to the online monitoring platform from the main dynamic controller as the new main dynamic controller;

[0042] Step 130: The new main dynamic controller acquires the connection status with multiple devices and uploads the connection status of the new main dynamic controller with multiple devices to the online monitoring platform;

[0043] Step 140: The new main dynamic controller sends a takeover prompt message to the online monitoring platform, which triggers the online monitoring platform to generate a fault alarm for the main dynamic controller.

[0044] To facilitate understanding of the present invention, the following description, in conjunction with embodiments, further illustrates the enterprise environmental monitoring data transmission method provided by the present invention, based on the principle of the present invention.

[0045] Specifically, this embodiment sets up two dynamic control units, namely a master dynamic control unit and a slave dynamic control unit. Each of the two dynamic control units is connected to three serial port distributors. The input terminals of the serial port distributors are connected to the two sets of dynamic control units respectively, and the output terminals are connected to online monitoring equipment, such as an analyzer. The number of serial port distributors depends on the number of online monitoring devices directly connected to the dynamic control units. Both dynamic control units are connected to the online monitoring platform. The enterprise environmental monitoring data transmission method includes:

[0046] S1. The two sets of dynamic control instruments use a serial cable as a heartbeat line to monitor each other's online status. The main dynamic control instrument receives monitoring data from multiple devices and forwards the monitoring data to the online monitoring platform.

[0047] S2. If the time elapsed since the last received heartbeat signal, as monitored by the dynamic controller, exceeds a preset threshold, then the main dynamic controller is confirmed to be faulty. After the secondary dynamic controller confirms the fault, it switches to a new main dynamic controller to take over the task of forwarding monitoring data from multiple devices to the online monitoring platform.

[0048] S3. The new master dynamic controller sends a takeover prompt to the online monitoring platform. This prompt triggers a fault alarm for the master dynamic controller on the online monitoring platform. Upon receiving the alarm, administrators repair the faulty master dynamic controller. The repaired master dynamic controller then becomes the new slave dynamic controller.

[0049] S4. The new main dynamic controller collects the connection status of each monitoring device (analyzer device, flue gas parameter device, particulate matter detection device). The new main dynamic controller saves the serial number of the locally identified monitoring device to the device list and uploads the device list to the online monitoring platform. The online monitoring platform compares the received device list with the pre-stored device list. If they match, it means that the device connection is normal; otherwise, the device connection is abnormal. Once a connection is abnormal, the online monitoring platform generates an alarm message.

[0050] S5. Currently, the primary dynamic controller periodically receives monitoring data from multiple devices and forwards this data as test data to the online monitoring platform. This test data serves as the standard for the online monitoring platform to verify the accuracy of the monitoring data uploaded by the primary dynamic controller. The monitoring data uploaded by the primary dynamic controller is compared with the test data; if they match, the monitoring data uploaded by the primary dynamic controller is deemed accurate.

[0051] Regular data consistency comparisons can promptly detect anomalies in the main dynamic control instrument, preventing a decrease in data accuracy.

[0052] The online monitoring platform performs statistical analysis on the monitoring data, generates monitoring charts based on the data, and displays the monitoring charts.

[0053] like Figure 2 As shown, the system 200 includes:

[0054] The status monitoring unit 210 is used to monitor the operating status of the main dynamic controller from the dynamic controller. The main dynamic controller receives monitoring data from multiple devices and forwards the monitoring data to the online monitoring platform.

[0055] The work takeover unit 220 is used to confirm the fault of the main dynamic controller from the dynamic controller, and take over the work of the main dynamic controller to forward the monitoring data of multiple devices to the online monitoring platform by the dynamic controller as the new main dynamic controller.

[0056] The communication upload unit 230 is used for the new main dynamic controller to acquire the connection status with multiple devices and upload the connection status of the new main dynamic controller with multiple devices to the online monitoring platform.

[0057] The alarm triggering unit 240 is used to send a takeover prompt message to the online monitoring platform from the new main dynamic controller. The takeover prompt message triggers the online monitoring platform to generate a fault alarm for the main dynamic controller.

[0058] Optionally, as an embodiment of the present invention, the step of monitoring the operating status of the master dynamic controller from the slave dynamic controller includes:

[0059] Receive heartbeat signals periodically sent by the main dynamic controller from the dynamic controller.

[0060] Optionally, as an embodiment of the present invention, the step of confirming a fault in the master dynamic controller via the slave dynamic controller includes:

[0061] If the time elapsed between the current moment and the last time the heartbeat signal was received exceeds a preset threshold, the main dynamic controller is confirmed to be faulty.

[0062] Optionally, as an embodiment of the present invention, the system further includes:

[0063] The status calibration unit is used to periodically receive monitoring data from multiple devices from the dynamic control instrument and forward the received monitoring data as test data to the online monitoring platform. The test data serves as the standard for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the main dynamic control instrument.
