Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a method and system for transmitting data of environmental monitoring of an enterprise. Background Art

[0002] With the increasing requirements for environmental protection, it is imperative to monitor the production of enterprises. Key pollutant-discharging units need to ensure the normal operation and data quality of automatic monitoring equipment through comparative monitoring, regular verification and calibration in accordance with standards and specifications, while ensuring data transmission rate and data efficiency.

[0003] However, in actual operation, the on-site CEMS equipment and the data acquisition and transmission instruments used are all online devices that run 24 hours a day. It is necessary to ensure stability and security as much as possible, and when problems occur, timely switch to the backup machine and notify the on-duty personnel to immediately start the emergency process.

[0004] Taking the dynamic control of waste gas pollution sources in power plants as an example, the conventional dynamic control system realizes the simultaneous monitoring of online detection equipment data, parameters, and status. At the same time, the network topology in the station is that the analyzer, flue gas parameter equipment, and particulate matter equipment are directly connected to the dynamic control instrument, and the dynamic control instrument is uploaded to the dynamic control platform of online monitoring equipment via wired or wireless means. The network is a serial connection. If the dynamic control instrument fails abnormally, the platform will lose data and cannot be retransmitted. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides an enterprise environmental monitoring data transmission method and system to solve the above-mentioned technical problems.

[0008] The slave dynamic controller confirms the failure of the master dynamic controller, and the slave dynamic controller serves as the new master dynamic controller to take over the work of forwarding the monitoring data of multiple devices to the online monitoring platform from the master dynamic controller;

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

[0011] Furthermore, the slave dynamic control instrument monitors the operating status of the master dynamic control instrument, including:

[0012] The slave dynamic controller receives the heartbeat signal sent periodically by the master dynamic controller.

[0013] Further, the slave dynamic control instrument confirms that the master dynamic control instrument is faulty, including:

[0014] If the time from the monitoring of the dynamic controller to the current time to the time when the heartbeat signal was last received exceeds a preset threshold, it is confirmed that the main dynamic controller is faulty.

[0015] Furthermore, the method further comprises:

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

[0018] Compare the monitoring data uploaded by the main dynamic control instrument with the test data for consistency. If the two are consistent, it is determined that the monitoring data uploaded by the main dynamic control instrument is accurate.

[0037] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0038] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention. Figure 1 The executing entity may be an enterprise environmental monitoring data transmission system.

[0039] like Figure 1 As shown, including a master dynamic control instrument and a slave dynamic control instrument, the method includes:

[0040] Step 110, the slave dynamic control instrument monitors the operating status of the master dynamic control instrument, the master dynamic control instrument receives monitoring data of multiple devices and forwards the monitoring data to the online monitoring platform;

[0041] Step 120, the slave dynamic control instrument confirms that the master dynamic control instrument is faulty, and the slave dynamic control instrument serves as a new master dynamic control instrument, taking over the work of the master dynamic control instrument forwarding the monitoring data of multiple devices to the online monitoring platform;

[0042] Step 130, the new master dynamic control instrument obtains the connection status with multiple devices, and uploads the connection status between the new master dynamic control instrument and the multiple devices to the online monitoring platform;

[0043] Step 140: the new active dynamic control instrument sends a takeover prompt message to the online monitoring platform, and the takeover prompt message triggers the online monitoring platform to generate an active dynamic control instrument fault alarm.

[0044] To facilitate understanding of the present invention, the enterprise environmental monitoring data transmission method provided by the present invention is further described below based on the principle of the enterprise environmental monitoring data transmission method of the present invention and in combination with an embodiment.

[0045] Specifically, in this embodiment, two dynamic control instruments are set, namely a master dynamic control instrument and a slave dynamic control instrument. The two dynamic control instruments are connected to three serial port distributors respectively. The input end of the serial port distributor is connected to the two sets of dynamic control instruments respectively, and the output end is connected to the online monitoring equipment, such as an analyzer; the number of serial port distributors depends on the number of dynamic control instruments directly connected to the online monitoring equipment. Both dynamic control instruments are connected to the online monitoring platform. The enterprise environmental protection monitoring data transmission method includes:

[0046] S1. The two sets of dynamic control instruments use serial lines as heartbeat lines to monitor each other to see if the other is online. 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 from the dynamic controller to the current time when the heartbeat signal was last received exceeds the preset threshold, the main dynamic controller is confirmed to be faulty. After the slave dynamic controller confirms that the main dynamic controller is faulty, the slave dynamic controller is switched to the new master dynamic controller to take over the work of forwarding the monitoring data of multiple devices to the online monitoring platform.

[0048] S3. The new master dynamic controller sends a takeover prompt message to the online monitoring platform, which triggers the online monitoring platform to generate a master dynamic controller fault alarm. After receiving the fault alarm, the manager repairs the faulty master dynamic controller. The repaired master dynamic controller serves as the new slave dynamic controller.

[0049] S4. The new main dynamic control instrument collects the connection status with each monitoring device (analyzer equipment, flue gas parameter equipment, particulate matter detection equipment). The new main dynamic control instrument saves the locally identified monitoring device serial number 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 for consistency. If the two are consistent, it means that the device connection is normal, otherwise the device connection is abnormal. Once the connection is abnormal, the online monitoring platform generates an alarm message.

[0050] S5. The current slave dynamic controller regularly receives monitoring data of multiple devices and forwards the received monitoring data as test data to the online monitoring platform. The test data is used as the standard for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the master dynamic controller. The monitoring data uploaded by the master dynamic controller is compared with the test data for consistency. If the two are consistent, the monitoring data uploaded by the master dynamic controller is determined to be accurate.

[0051] Through regular data consistency comparison, abnormalities of the main dynamic control instrument can be discovered in time to avoid reduced data accuracy.

[0052] The online monitoring platform collects statistics on the monitoring data, generates monitoring charts based on the monitoring 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 control instrument from the dynamic control instrument, and the main dynamic control instrument receives the monitoring data of multiple devices and forwards the monitoring data to the online monitoring platform;

[0055] The work taking over unit 220 is used to confirm that the master dynamic control instrument is faulty from the slave dynamic control instrument, and the slave dynamic control instrument serves as a new master dynamic control instrument to take over the work of the master dynamic control instrument forwarding the monitoring data of multiple devices to the online monitoring platform;

[0056] The communication uploading unit 230 is used for the new master dynamic controller to obtain the connection status with multiple devices, and upload the connection status between the new master dynamic controller and multiple devices to the online monitoring platform;

[0057] The alarm triggering unit 240 is used for the new master dynamic control instrument to send a takeover prompt message to the online monitoring platform, and the takeover prompt message triggers the online monitoring platform to generate a master dynamic control instrument failure alarm.

[0058] Optionally, as an embodiment of the present invention, the slave dynamic control instrument monitors the operating status of the master dynamic control instrument, including:

[0059] The slave dynamic controller receives the heartbeat signal sent periodically by the master dynamic controller.

[0060] Optionally, as an embodiment of the present invention, the slave dynamic control instrument confirming that the master dynamic control instrument is faulty includes:

[0061] If the time from the monitoring of the dynamic controller to the current time to the time when the heartbeat signal was last received exceeds a preset threshold, it is confirmed that the main dynamic controller is faulty.

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

[0063] The status check unit is used to periodically receive monitoring data of 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 a standard for the online monitoring platform to detect the accuracy of the monitoring data uploaded by the main dynamic control instrument.
