[0023] The functions of the black box display are: through mouse or keyboard operations, it can be selected to display the following data; display the basic information and alarm message list; display the collected real-time data list; display the saved historical data in a chart for a specified time period;

[0024] The network transmission module is wireless 4G, which can timely transmit the real-time data and alarm messages collected by the black box back to the superior environmental protection cloud platform;

[0025] The data memory, with a capacity of 256 GB (or 512 GB, depending on the number of enterprise boilers), has two storage areas, the main and the backup, and can ensure the recording and preservation of massive historical data for ten to twenty years.

[0026] The Ethernet data interface, a MODBUS_TCP client, reads data from the enterprise server.

[0027] The serial communication interface RS232: a MODBUS_RTU master station, reads data from enterprise slave stations.

[0028] The serial communication interface RS485: a MODBUS_RTU master station, reads data from enterprise slave stations.

[0029] The black box mouse, keyboard and USB interface: for browsing black box data, and managers can use it to copy the data recorded by the black box.

[0030] The external interface machine: This is to facilitate some enterprises to provide data through the network OPC protocol or other means. To ensure the secure isolation between the enterprise network and the external network, a data conversion function service is provided outside the black box. The interface machine converts OPC_DA into a MODBUS_RTU serial port service, and then is connected to the black box through an isolation device. This device is not necessary and depends on the specific situation of the enterprise.

[0031] In view of the situation that internal devices in the enterprise are scattered and unable to provide data through a unified interface, an internal network is formed by combining the enterprise internal device networking Lora WAN and the interface machine, and the interface machine uniformly provides enterprise data for the black box, or multiple devices are all MODBUS_RTU serial port services, with different station numbers. For those where serial cables cannot be laid, Lora WAN is laid, and the black box master station accesses multiple slave stations to obtain data.

[0032] The cabinet 1 is an enclosed structure surrounded by a top seat 11, a base 12, a rear cabinet door 13, a front cabinet door 14 and two side plates 15. Among them, the rear cabinet door 13 and the front cabinet door 14 are both hinged to the corresponding side plates 15. The setting of the front and rear doors is conducive to operations such as viewing, maintenance and installation of the monitoring devices inside the cabinet 1. This black box also includes a cooling fan. A number of exhaust holes 111 are longitudinally opened on the top seat 11. The cooling fan is installed inside the cabinet 1 and its position corresponds to that of the exhaust holes 111. When the cooling fan works, an air flow from bottom to top can be formed inside the cabinet 1, and the air flow can take away the heat generated when the monitoring devices work.

[0033] The base 12 is a box-shaped structure with an open upper end. In order to form an upward airflow, a plurality of air inlet holes 121 are provided on the four side walls of the base 12, and the plurality of air inlet holes 121 are arranged in an array; three wire inlet holes 122 are provided on the bottom wall of the base 12. When no device is installed, the wire inlet holes 122 are closed by plastic covers; the cabinet 1 further includes a partition frame 16 and four filter plates 17; the partition frame 16 is provided on the bottom wall of the base 12 and is located inside the base 12; the partition frame 16 has a square structure, and accommodation grooves are formed between the four component surfaces of the partition frame 16 and the four side walls of the base 12. At this time, the partition frame 16 and the base 12 form a structure similar to a double-square shape; when the outside air enters the cabinet 1, it will collide with the partition frame 16, and dust will be centrally retained in the accommodation groove under the blocking of the partition frame 16;

[0034] In order to further improve the dust-proof ability, the cabinet 1 further includes four filter plates 17; the four filter plates 17 are arranged in the accommodation grooves and the four filter plates 17 are arranged corresponding to the four side walls of the base 12 one by one. The filter plates 17 are in surface contact with the side walls of the base 12, while the filter plates 17 are kept at a distance from the partition frame 16. At this time, the filter plates 7 cover the corresponding air inlet holes 121. When the cooling fan works, the airflow enters the interior of the cabinet 1 after passing through the air inlet holes 121 and the filter plates 17 in sequence, and finally is discharged from the cabinet 1 through the cooling fan. Due to the fixing effect of the partition frame 16, the filter plates 17 are stably installed. At the same time, the filter plates 17 can filter the air entering the cabinet 1 to achieve the dust-proof effect; in addition, the filter plates 17 are movably placed in the accommodation grooves, which is convenient for replacing the filter plates 17 in the later stage; it can be understood that the air is initially filtered by the filter plates 17 after entering the cabinet 1 and is re-filtered by the partition frame 16.

[0035] In one embodiment, in order to filter the air entering the interior of the cabinet 1, as a further supplement, a filter net can be provided at the notch of the accommodation groove to close the upper part of the accommodation groove. The mesh number of the filter net can be selected from 20 to 50 meshes. After the air enters the cabinet 1, it is greatly purified under the action of the filter plates and the partition frame 16. The finer dust particles in the purified air will be further purified under the blocking and filtering of the filter net, ensuring the dust-proof ability of this black box when the filter plates fail.

[0036] This black box not only has a high dust-proof ability, but also has the ability to process a series of tasks such as data collection, storage, upload, and alarm judgment of the entire production process data of the enterprise. It can quickly analyze and judge on-site. It has changed from traditional target emission supervision to on-site production process supervision of the enterprise, and has made comprehensive data records for each link of production: whether the process is reasonable, whether the control is optimized, whether the operation is timely and compliant, whether the purification consumables are reasonably invested, whether the purification equipment is well maintained, etc. For each enterprise, by analyzing and summarizing the collected various data, it can provide effective evidence for supervision. When a problem occurs, it can completely reproduce the process state when the problem occurred afterwards, which is convenient for verifying the cause of the accident.

[0037] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
