Description

Technical Field

[0001] The present invention relates to the technical field of gas detection, and in particular to an interconnected security system based on Star Flash technology combined with 5G-RedCap. Background Art

[0002] Gas detection is a very important task in industrial sites. Since many chemicals are toxic, flammable and explosive, they need to be monitored and controlled to ensure the safety of employees and equipment. In many industrial sites, fixed detection equipment and portable detection equipment are involved. Fixed detection equipment is fixed on the wall or other objects, and portable detection equipment is generally held by employees. Employees need to be exposed to various chemicals, such as organic solvents, ammonia, hydrogen sulfide, etc. These chemicals may cause symptoms such as headaches, nausea, and difficulty breathing, and in severe cases may even lead to death. Therefore, real-time monitoring of gases in industrial sites can help employees avoid being harmed by these harmful gases and protect their health and safety.

[0003] The existing interconnected security system requires inspectors to hold handheld inspection equipment and be equipped with pagers or intercoms to make judgments based on their experience. However, when danger occurs, the inspectors manually send out alarm information to notify other personnel, which is slow, especially when it needs to be transmitted layer by layer.

[0004] NearLink is a new type of wireless short-range communication standard technology and a new generation of short-range wireless connection technology native to China. NearLink combines the advantages of Bluetooth and WiFi, with the characteristics of low power consumption, high speed, and low latency. It can support the interconnection of a large number of devices with extremely low latency and is backward compatible with Bluetooth and WiFi. In addition, NearLink also has the characteristics of high synchronization accuracy, high reliability, and high security. It is suitable for a variety of scenarios such as smart homes, smart cars, and smart manufacturing, providing users with a more efficient and stable wireless connection experience. At the same time, it also introduces 5G key technologies such as Polar codes and innovative concepts such as central scheduling to bring stronger anti-interference and high concurrency capabilities.

[0005] 5G-RedCap technology, also known as Reduced Capability 5G, is a lightweight version of 5G technology that aims to provide lower-cost, lower-power communication solutions. By simplifying the complexity of network equipment and terminals, it reduces overall costs and energy consumption while maintaining the core advantages of 5G networks such as large bandwidth and low latency. Summary of the invention

[0006] In order to solve the technical problems of complex wiring and high cost caused by wired connections in existing interconnected security systems, the present invention proposes an interconnected security system based on Star Flash technology combined with 5G-RedCap. Fixed detection equipment, portable detection equipment, and concentrators are all equipped with Star Flash communication modules to realize mesh networking within the area, which can form a security line in the area and eliminate the cost and wiring difficulties caused by wired connections.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: an interconnected security system based on Star Flash technology combined with 5G-RedCap, including a concentrator and a cloud platform, and also including multiple detection devices. The concentrator and the multiple detection devices are each provided with a Star Flash communication module, and adjacent detection devices and the concentrator and the detection devices communicate through the Star Flash communication module; the concentrator is also provided with a 5G-RedCap module, and the concentrator is connected to the cloud platform through the 5G-RedCap module, and the cloud platform is connected to the mobile terminal.

[0008] Preferably, the detection equipment includes a portable detection equipment and a fixed detection equipment, the portable detection equipment and / or the fixed detection equipment are connected to the concentrator via the Star Flash communication module, and adjacent portable detection equipment and / or are connected via the Star Flash communication module.

[0009] Preferably, the concentrator is arranged near any fixed detection device to aggregate the operating status of each detection device in the network, and report the device status in the network to the cloud platform, which is pushed to the supervisor's mobile terminal via the cloud platform.

[0010] Preferably, the concentrator and multiple detection devices, as well as multiple detection devices, are networked through the Star Flash communication module to formulate networking logic and rules for users, and the networking adopts a method that combines flooding network and dynamic routing network.

[0011] Preferably, the flooding network transmits the alarm information via a flooding algorithm.

[0012] Preferably, the method of transmitting alarm information in a flooding network is as follows: when an alarm event occurs in a detection device or a concentrator, the initiating device transmits the alarm information, and when the other devices receive the alarm information sent by the initiating device, they forward the data after a random delay based on their own device numbers; when the initiating device transmits the alarm information, it enters the monitoring mode, and if it does not receive the forwarding information from the other devices within a certain period of time, it needs to be resent; the other devices also enter the monitoring mode after forwarding, and if they do not hear the forwarding information from the remaining devices, they need to be resent.

[0013] Preferably, the dynamic routing network transmits heartbeat data by building a dynamic routing table, and the detection device periodically sends heartbeat data to the concentrator for a heartbeat keep-alive transmission mechanism.

[0014] Preferably, the dynamic routing network is mainly initiated by the concentrator, and the concentrator initiates table building information. The content of the table building information carries its own device number and table building level. After receiving the table building information, the nearby detection device does not respond, but sends the table building information after a random delay. The content of the table building information also carries its own device number and table building level, and the table building level increases and is transmitted layer by layer.

[0015] Preferably, when heartbeat transmission is required, dynamic routing transmission can be completed according to the address of the table building information, and the response information is returned along the original route; when table building information is received from multiple detection devices, the device compares and filters according to the RSSI values ​​of the same table building level to be received, and selects the detection device with a small table building level and a strong RSSI value signal strength.

[0016] Preferably, the table building path is determined by filtering the detection device according to the principle of selecting a small table building level and a strong signal strength of the RSSI value. When the detection device needs to initiate a heartbeat message, the heartbeat data is transmitted in the reverse direction of the table building path, and the response transmission direction of the response information of the concentrator is the direction of the table building path; Each time the concentrator initiates table building information, the table building information needs to be refreshed periodically. The heartbeat time of the detection device is discretely processed according to actual needs and the device heartbeat cycle to ensure that only one detection device in the group initiates a heartbeat at the same time; The concentrator realizes the OTA function by transmitting text between the 5G-RedCap module and the cloud platform through the HTTP protocol.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0028] The present invention designs an interconnected security system based on Star Flash technology combined with 5G-RedCap. The specific topology diagram is as follows: Figure 1 As shown, it includes a concentrator 4, a cloud platform 2 and multiple detection devices. The concentrator 4 is provided with a first star flash communication module and a 5G-RedCap module, and the detection device is provided with a second star flash communication module. The concentrator 4 is connected to the detection device through the first star flash communication module and the second star flash communication module, and the adjacent detection devices are connected through the second star flash communication module. The concentrator 4 is connected to the cloud platform 2 through the 5G-RedCap module. The cloud platform 2 is connected to the mobile terminal 3.

[0029] The detection equipment includes a portable detection device 1 and a fixed detection device 5. The portable detection device 1 and the fixed detection device 5 are connected to the first star flash communication module of the concentrator 4 through the second star flash communication module. The portable detection device 1 and the fixed detection device 5 perform dangerous gas detection in the same area. The fixed detection device 5 is installed in a fixed position, generally on a wall or a concrete pillar, and the operator carries the portable detection device 1. The concentrator 4 is set near any fixed detection device 5 to aggregate the operating status of each detection device in the network, and at the same time report the device status in the network to the cloud platform 2, and push it to the supervisor's mobile terminal 3 through the cloud platform 2.

[0030] Among them, the portable detection device 1, the fixed detection device 2 and the concentrator 4 are all equipped with a Star Flash communication module, which is used for intra-regional networking. Each device has both a node-initiated transmission function and a relay function. The intra-group network adopts a method that combines a flooding network and a dynamic routing network. The Star Flash communication module is a transparent transmission module that can realize the data transparent transmission function. Multiple detection devices initiate data through the Star Flash communication module, and only a simple delay and staggered transmission is required to form a flooding network communication. Through the dynamic routing network, data is transmitted sequentially and purposefully between detection devices. The networking logic and rules are formulated for users through the Star Flash communication module, so it is easier to expand.

[0031] The flooding network is used for alarm information transmission. The flooding network transmits alarm information through a flooding algorithm. When the portable detection device 1, the fixed detection device 2 or the concentrator 4 has an alarm event such as an alarm, an alarm cancellation, or a device failure, the initiating device A transmits the alarm information. When the other devices B and C receive the alarm information sent by the initiating device A, each detection device has its own 6-byte number, and forwards the data after a random delay according to its own device number. All other devices operate in the same way. After the initiating device A sends an alarm transmission, it enters the monitoring mode. If it does not receive the forwarding information from the other devices within 5s, it needs to resend to ensure that the other devices have received it. The other devices B and C also need to enter the monitoring mode after forwarding. If they do not hear the forwarding information from other devices, they need to resend to ensure that the other devices have received it. The data is sent only after a simple peak-shifting delay, which is the fastest sending logic. There is no other sending logic and avoidance measures, which can ensure the timeliness of data delivery.

[0032] The dynamic routing network is used for the heartbeat keep-alive transmission mechanism, and the heartbeat transmission is performed through dynamic routing table building. The normal working mode is that the fixed detection device 5 must regularly send heartbeat data to the concentrator 4. If a portable detection device 1 is working, it can also participate in the transmission. The dynamic routing network is mainly initiated by the concentrator 4. The concentrator 4 initiates the table building information of the route. The content of the table building information carries its own device number and table building level. The nearby detection devices do not respond after receiving it. After a random delay, the table building information is also sent. The content of the table building information also carries its own device number and table building level. For example, if the level of the received table building information is 1, then the sent table building information needs to be added by 1, and it is transmitted layer by layer. All detection devices know which device initiated the received table building information. When heartbeat transmission is required, the dynamic routing transmission can be completed according to the address of the table building information, and the response information is returned along the original route. Each device must have a 6-byte device ID written into it before leaving the factory. When the table information is created, if device A sends the table information, device B will know the address of device A after receiving it, and the upper level address of device B is device A. Similarly, ABCD, the upper level of device C is device B, and the upper level of device C is device D. If device D sends a heartbeat, the order is DCBA, and the response frame order is ABCD. The response information is the response of the initiator of the table creation to the initiator of the heartbeat, indicating that it has been received.

[0033] For example: The equipment layout of the four areas B, C, and D is as follows: Figure 3 As shown in the figure, different functional areas only indicate the distribution of equipment. Area A is the area where the concentrator 1 is located, and the rest of the area is the fixed detection equipment 5 or the portable detection equipment 1. The concentrator---device 1 initiates the table building information, and the receiving devices send the table building information in turn. The data coverage range in the process of table building information in the network is as follows Figure 4 As shown. Simply put, when device 1 sends metering information, the communication is limited by distance. Devices 5, 14, and 15 can all receive it, but device 2 cannot. Then, when devices 5, 14, and 15 send metering information, device 1 will also receive it, as will devices around devices 5, 14, and 15. Communication can be established when the distance between devices is less than a certain threshold. Figure 4As shown in the figure, device 5 receives the meter building information for the first time, processes the data and sends the meter building information. After receiving the meter building information, device 4 will still send the meter building information after data processing. At this time, device 5 does not process the meter building information of device 4. Similarly, device 2 and device 15 will receive meter building information sent by multiple devices. At this time, device 2 and device 15 will compare and filter according to the RSSI (Received Signal Strength Indication) value of the same meter building level to be received, and select the detection device with a small meter building level and a strong RSSI value. When receiving data, the RSSI value of this data can be read inside the module.

[0034] Through the judgment and filtering process in the program, the one-way construction is shown as follows Figure 5 shown. Figure 5 According to the principle of selecting a small table building level and filtering the routing table building path with a large signal strength of the RSSI value, each device can receive the table building information. When devices between 2-15 need to initiate heartbeat information, according to the table building path, the upper-level device of device No. 13 in area D is device No. 11, and the upper-level device of device No. 11 is device No. 10 in area C. When device No. 13 initiates heartbeat transmission, the heartbeat data is transmitted in the opposite direction of the table building path, and the route is: 13-11-10-9-8-3-4-1. The response transmission direction of the response information of device No. 1, that is, the table building path direction, is 1-4-3-8-9-10-11-13, such as Figure 6 shown.

[0035] Concentrator 4, i.e., device No. 1, initiates table creation information each time. Since there is a portable detection device in the device, there is a possibility of movement or being taken away, so the table creation information needs to be refreshed periodically. To avoid multiple devices initiating heartbeats at the same time, you can consider it according to actual needs and the device heartbeat cycle. At the same time, the heartbeat time of the device needs to be discrete to ensure that only one device in the group initiates a heartbeat at the same time. Device No. N needs a heartbeat once an hour, and there are M devices in total. The heartbeat time interval is N*3600 / M. If the number is 2 and the total number of devices is 50, the time that a device can transmit is 3600 / 50=72S, and device No. 2 starts reporting in the second 72S, and the user can start calculating from the hour. For example, if there are 50 devices, numbered 1-50, and 3600 seconds per hour, and the transmission is completed within one hour, then each device has 72 seconds. Each device has an RTC chip inside, which can obtain the clock. Each device starts calculating the time after the hour. For example, at 5:00, device No. 1 uploads at 5 o'clock, and device No. 2 uploads at 5:72 seconds, that is, 5:00 01:12 seconds, and so on, to ensure that only one device initiates a heartbeat at each time.

[0036] HTTP is an application layer protocol, consisting of requests and responses, using a standard client-server model. It not only ensures that computers can transmit hypertext documents correctly and quickly, but also determines which part of the document to transmit and which part to display first, thereby making the browser more efficient and reducing network transmission.

[0037] OTA online upgrade (Over-The-Air) is a remote update technology that allows devices to directly download and install new software versions or firmware via the Internet without the user having to send the device back to the manufacturer for physical update. Concentrator 4 is a monitoring and aggregation terminal in the group, and OTA function is indispensable. The OTA function can be quickly implemented by transmitting text between the 5G-RedCap module and the cloud platform 2 through the HTTP protocol, which is much more convenient than TCP to transmit BIN file data frame by frame. At the same time, the 5G-RedCap module packages the network group data in the concentrator 4 and sends it to the cloud platform 2, which can continue to push it to the user's mobile terminal 3, that is, the handheld terminal.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
