[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the schematic embodiments of the present invention and their description are used to explain the present invention, but are not intended to limit the present invention.

[0052] Example 1

[0053] As attached Figure 1-5 As shown, this embodiment discloses a combustible gas detection system for the single crystal industry, which is used to collect and summarize combustible gas data and provide corresponding alarm feedback based on the data. The system mainly includes: a detection alarm module 1, a PLC control module 3, and a host computer module 5. When in use, the detection alarm module 1 will collect data on combustible gas leaks on site in real time. The detection alarm module 1 can provide corresponding alarm feedback based on the situation of its own collected data; then, the detection alarm module 1 transmits the data to the PLC control module 3 through the first signal transmission module 2, and the PLC control module 3 analyzes and processes the data; thereafter, the PLC control module 3 transmits the analyzed and processed information to the host computer module 5 through the second signal transmission module 4, and the host computer module 5 can summarize the information to facilitate the user to perform corresponding analysis and tracing of the information later.

[0054] The specific structure of the combustible gas detection system for the single crystal industry is as follows: it includes a detection and alarm module 1, which is connected to a PLC control module 3 via a first signal transmission module 2, and the PLC control module 3 is connected to a host computer module 5 via a second signal transmission module 4. Compared to the existing technology, the present invention can centrally collect and aggregate data on leaked combustible gas, thereby accurately triggering alarms without affecting subsequent analysis and tracing of the target data.

[0055] In a specific application scenario, as shown in the attached Figure 2 As shown, the detection and alarm module 1 includes a combustible gas sensor 13, a control board 12, a storage board 11, and a first alarm unit 15. The combustible gas sensor 13 in the detection and alarm module 1 is electrically connected to the control board 12; the control board 12 is electrically connected to the storage board 11, and the storage board 11 and the control board 12 can communicate with each other. The first alarm unit 15 in the detection and alarm module 1 includes a first relay 151 and a buzzer 152. The control board 12 is electrically connected to the first relay 151, and the first relay 151 is electrically connected to the buzzer 152.

[0056] In actual use, the combustible gas sensor 13 collects data on combustible gas leakage within the current range of the site, and the data mainly represents the concentration information of the combustible gas leakage; then, the combustible gas sensor 13 transmits the combustible gas concentration information to the control board 12 through a wire; the control board 12 can transmit the combustible gas concentration information to the storage board 11 through a wire, and the storage board 11 saves the concentration information; then, the storage board 11 transmits the preset threshold data and concentration information to the control board 12 through a wire. When the concentration of the combustible gas is equal to or greater than the threshold data, the detection alarm module 1 performs an alarm feedback; otherwise, the detection alarm module 1 does not perform an alarm feedback; specifically, after the control board 12 receives the threshold data from the storage board 11, the control board 12 The board 12 compares the threshold data with the currently collected concentration of the combustible gas; then, a comparison result is obtained; if the result obtained by the control board 12 after comparison is that the concentration of the combustible gas is less than the threshold data preset in the storage board 11, the control board 12 sends a shutdown instruction to the first relay 151, and the current between the first relay 151 and the buzzer 152 will not be conducted, and the buzzer 152 will not work. The detection alarm module 1 detects that the current concentration of the combustible gas does not exceed the standard, so no alarm feedback is performed; otherwise, the control board 12 sends a turn-on instruction to the first relay 151, and the current between the first relay 151 and the buzzer 152 is conducted, and the buzzer 152 continues to work. The detection alarm module 1 detects that the current concentration of the combustible gas exceeds the standard, and therefore, an alarm feedback is performed.

[0057] In the field equipment, such as the attached Figure 5 As shown, the detection and alarm module 1 includes a silicon block recycled water combustible gas detection and alarm unit, a hydrogen production device combustible gas detection and alarm unit, and a hazardous waste storage combustible gas detection and alarm unit. They transmit the combustible gas data they collect to the PLC control module 3 through the first signal transmission module 2 respectively. The PLC control module 3 transmits these data to the host computer module 5 through the second signal transmission module 4 for summary processing, so that the user can perform corresponding analysis and tracing of the information later.

[0058] In a specific application scenario, the first signal transmission module 2 adopts the MODBUS-RTU transmission protocol, and the second signal transmission module 4 adopts the TCP / IP transmission protocol.

[0059] In actual use, the detection and alarm module 1 can transmit the collected data to the PLC control module 3 via the MODBUS-RTU transmission protocol, which is efficient, reliable, and has an open standard. The PLC control module 3 can also transmit the analyzed and processed information to the host computer module 5 via the TCP / IP transmission protocol. The PLC control module 3 can be a PLC controller. This PLC controller uses the PLC as its basic architecture, replacing the control structure of a traditional single-chip microcomputer. It can aggregate and process the data it receives and perform corresponding analysis. Therefore, the PLC controller has the advantages of high reliability, strong anti-interference ability, and easy maintenance.

[0060] In a specific application scenario, the host computer module 5 includes a memory 51, a controller 52, an LCD display 54, and an operation keyboard 53. The memory 51 in the host computer module 5 is used to store information transmitted by the PLC control module 3, thereby achieving the effect of aggregating and uniformly managing the information; the memory 51 is electrically connected to the controller 52, and the controller 52 and the memory 51 can communicate with each other; the controller 52 is electrically connected to the LCD display 54, and the controller 52 is electrically connected to the operation keyboard 53.

[0061] In actual use, the memory 51 can transmit the data stored in itself to the controller 52 through a wire; similarly, after analysis and processing, the controller 52 can feedback the data it needs to the memory 51, and the memory 51 can transmit the corresponding data to the controller 52 through a wire; in this process, the host computer module 5 achieves the purpose of recording and analyzing historical data; the controller 52 can transmit the analyzed data to the LCD display 54 through a wire; wherein, the data transmitted by the controller 52 to the LCD display 54 is an analog signal, and the LCD display 54 needs to convert the analog signal into a digital signal; or, before sending data to the LCD display 54, the controller 52 converts the corresponding data from an analog signal to a digital signal; then, the corresponding information appears on the LCD display 54 for the user to view, thereby achieving the purpose of real-time monitoring; in addition, the user can feedback the data or information he needs to the controller 52 by tapping the operation keyboard 53. Under the action of the aforementioned memory 51 and controller 52, the corresponding data or information can appear on the LCD display 54, thereby improving the convenience of operating the host computer module 5.

[0062] In another specific application scenario, the host computer module 5 can be a PC host computer; in addition, the PC host computer can be connected to the speaker 55 using a data cable; wherein the speaker 55 is electrically connected to the controller 52 via the data cable.

[0063] In actual use, the staff can input the threshold data of combustible gas into the PC host computer, and the threshold data is stored in the memory 51, and the threshold data is equal to the aforementioned threshold data; the PLC control module 3 transmits the collected combustible gas data to the PC host computer through the TCP / IP transmission protocol; in this process, the combustible gas data will be stored in the memory 51 of the PC host computer; then, the memory 51 will transmit the combustible gas data and the threshold data to the controller 52 through the wire; then, the controller 52 will compare and analyze the data collected by the silicon block recycled water combustible gas detection alarm unit, the data collected by the hydrogen production device combustible gas detection alarm unit and the data collected by the hazardous waste warehouse combustible gas detection alarm unit with the threshold data respectively; then, the corresponding results will be transmitted to the LCD display 54 through the wire, and the relevant information will appear on the screen; at this time, the user can quickly identify which units or The controller 52 can detect which areas of combustible gas leakage have exceeded the standard and process specific areas. This design can save time in processing combustible gas and improve work efficiency. In addition, when the collected combustible gas exceeds the standard, the controller 52 sends an alarm instruction to the speaker 55 via the data line. At this time, the speaker 55 will emit a preset alarm sound to remind the user or staff that the combustible gas leakage in a certain area exceeds the standard. The reason for connecting the PC host computer to a speaker 55 is that the buzzer 152 in the aforementioned detection alarm module 1 is generally very quiet when working. The staff needs to walk around the buzzer 152 to hear the buzzer 152 working sound and then determine whether the combustible gas leakage in the current area exceeds the standard. Now, by connecting the PC host computer to a speaker 55 and setting a general alarm feedback, the staff who monitors the PC host computer can immediately know the current combustible gas leakage status in each area and then arrange the corresponding staff to deal with it in the corresponding area. Therefore, the PC host computer realizes the purpose of displaying combustible gas leakage data, real-time monitoring, reporting and recording, analyzing historical data, and providing alarm feedback.

[0064] Example 2

[0065] As attached Figure 1-5As shown, this embodiment discloses a harmful gas detection system for the single crystal industry. In addition to the components of the aforementioned embodiment 1, it also includes a toxic gas sensor 14. During use, the detection and alarm module 1 can collect data on both combustible gas leaks and toxic gas leaks, and generate alarm feedback through the first alarm unit 15 based on the actual situation. This embodiment adds the functions of the aforementioned embodiment 1, and therefore has higher practicality.

[0066] In a specific application scenario, the toxic gas sensor 14 is provided in the detection alarm module 1 , and the toxic gas sensor 14 is electrically connected to the control board 12 .

[0067] In actual use, the threshold data of toxic gases are pre-set in the storage board 11 of the detection alarm module 1 and the memory 51 of the host computer module 5; the toxic gas sensor 14 transmits the collected toxic gas concentration data to the control board 12 through a wire, and the control board 12 transmits the toxic gas concentration data to the storage board 11; then, the storage board 11 transmits the threshold data and the concentration data to the control board 12, and the control board 12 compares the toxic gas concentration data with the toxic gas threshold data. If the currently collected toxic gas does not exceed the standard, the buzzer 152 in the detection alarm module 1 does not work; otherwise, the buzzer 152 in the detection alarm module 1 works, thereby reminding nearby staff that the toxic gas leaked in the current area exceeds the standard and needs to be processed accordingly.

[0068] In another specific application scenario, as shown in the attached Figure 5 As shown, the detection and alarm module 1 of the on-site equipment also includes a toxic gas detection and alarm unit for the hydrogen production device, a toxic gas detection and alarm unit for the material preparation room, and a toxic gas detection and alarm unit for the acid production room. They transmit the harmful gas data they have collected to the PLC control module 3 through the first signal transmission module 2 respectively. The PLC control module 3 transmits these data to the host computer module 5 through the second signal transmission module 4 for aggregation, so as to facilitate the user to conduct corresponding analysis and tracing of the information later.

[0069] In another specific application scenario, the aforementioned detection alarm module 1 can be a combustible gas and toxic gas detection alarm, and the user can set the detection alarm in the area where detection or collection is required. The utility model is based on PLC and receives data collected by the combustible gas and toxic gas detection alarm through the MODBUS-RTU communication protocol. The PLC controller analyzes and controls the data collected in each area (the PLC controller generally also sets the threshold data for combustible gas and toxic gas). The PLC controller transmits all the analyzed and processed data to the PC host computer through the TCP / IP communication protocol. The PC host computer then summarizes, classifies, displays and alarms the data. Therefore, the utility model successfully constructs a combustible gas detection system and a toxic gas detection (GDS) system for the single crystal industry.

[0070] The following will be based on Figure 6 The circuit diagram shown in the figure is used to illustrate the corresponding technical solutions in Example 1 and Example 2, and the specific contents are as follows: the 220VAC / 24VDC in the circuit serves as the power supply voltage of the entire system. The power supply voltage flows through the CPU 1214C (the aforementioned PLC control module 3) through the L (live wire) and the N (neutral wire), providing the CPU 1214C with a stable 24V DC voltage, so that the CPU 1214C can operate normally; in addition, the power supply voltage also flows through the argon gas station, the hydrogen production station, the M1 warehouse, the two silicon block return water A3 acid production rooms and the A3 preparation rooms 102, the A3 preparation rooms 103, the argon gas control room host computer (the aforementioned host computer module 5), CM 1241-1, CM 1241-2, CM 1241-3, and finally flows into the PE (ground wire) to form a power supply loop, thereby meeting the power supply requirements of the entire system; wherein, the CPU 1214C adopts CM 1241-1, CM 1241-2, CM The TCP / IP port in 1241-3 connects the CPU 1214C to the host computer in the argon gas control room through a TCP / IP data transmission line. This design can realize data transmission between the CPU 1214C and the host computer in the argon gas control room; the argon gas station, hydrogen production station, M1 warehouse, two silicon block return water A3 acid production rooms, and A3 preparation rooms 102 and A3 preparation rooms 103 are all equipped with the aforementioned combustible gas and toxic gas detection alarm (not shown in the circuit diagram, and the detection alarm is the aforementioned detection alarm module 1). The detection alarm uses the MODBUS-RTU port in CM 1241-1, CM 1241-2, and CM 1241-3, and is connected to the CPU 1214C through a MODBUS-RTU data transmission line. This design can realize data transmission between the combustible gas and toxic gas detection alarm and the CPU 1214C.
