Description

Technical Field

[0001] This utility model belongs to the field of communication equipment technology, and specifically relates to an amplifiable dual-ring information system. Background Technology

[0002] The main obstacles to mine communication:

[0003] Complex terrain structure: underground tunnels are winding, narrow and irregular in structure, which makes it difficult for wireless signals to propagate, easy to attenuate and multipath interference; rocky surrounding rocks, metal equipment and other materials can shield or reflect signals.

[0004] Harsh environment

[0005] The presence of dust, water vapor, high temperature, and high humidity can easily affect the stable operation of electronic equipment; flammable and explosive gases such as methane and coal dust limit the selection of communication equipment and require intrinsically safe design.

[0006] Frequent human activities

[0007] The equipment is susceptible to damage from construction, blasting, and mechanical vibration, which can lead to communication interruptions. Frequent movement of vehicles and personnel also poses challenges to communication coverage.

[0008] Depth and distance issues: Communication signals need to penetrate a large number of rock layers, resulting in severe penetration loss, especially in deep mines.

[0009] The difficulties of using wired communication:

[0010] Although wired communication (such as fiber optics and cables) has the advantages of stable signal and strong anti-interference ability, its use in mines also presents many difficulties:

[0011] Cable laying is difficult due to the narrow alleyways and limited space, requiring cables to avoid tracks, ventilation pipes, water pipes, etc.; the construction environment restricts the use of large tools, and manual laying is a large workload.

[0012] Highly vulnerable: the cable is easily crushed by mining trucks, cut by excavating equipment, or broken by falling rocks; once damaged, it is difficult to repair and may cause widespread communication outages.

[0013] Expansion and maintenance are complex: tunnels are frequently expanded or their layouts changed, and rewiring is time-consuming and labor-intensive; fault location is difficult, especially in complex underground networks.

[0014] High cost: High safety requirements (such as intrinsically safe cables and flame-retardant materials) result in higher material and installation costs; maintenance also requires professional personnel, leading to continuous cost accumulation.

[0015] Poor emergency response capability: In the event of an emergency (such as a collapse or flood), wired communication is easily damaged and has a long recovery period, which is not conducive to emergency communication support. Utility Model Content

[0016] To achieve the above objectives, the technical solution of this utility model is as follows: an augmentable dual-ring information system, the system including a first link, a second link and a server, the first link including a first monitor, the second link including a second monitor, the first monitor in the first link being further provided with a plurality of first monitors at the end, the second monitor in the second link being further provided with a plurality of second monitors at the end, the first link and the second link forming a dual-ring layout.

[0017] As an improvement of this utility model, the first or second monitor includes an oxygen / carbon dioxide detection module, a dust detection module, and a temperature and humidity detection module. The first or second monitor issues an alert when it detects oxygen / carbon dioxide, dust, and temperature and humidity environmental information. The oxygen / carbon dioxide detection module, dust detection module, and temperature and humidity detection module are all existing modules.

[0018] As an improvement of this utility model, the system is set at a height of 1.5m.

[0019] Based on the above technical features, the height of the server, monitor, and power-required devices is 1.5m.

[0020] As an improvement of this utility model, the receiving sensitivity of the upstream / downstream and nearby backup link devices is >-74dBm.

[0021] As an improvement to this invention, a new link device is also connected to the first link. For example, MAP_a2 is connected to MAP_a1, MAP_a3, and MAP_b9.

[0022] This utility model provides two solution mechanisms;

[0023] Option 1: Serial design: It has directional networking capability; the device can automatically wake up / sleep, or can be woken up by a server command; the dual-ring links can form new local areas, or use a hybrid communication protocol;

[0024] Option 2: Discrete layout: Automatic device wake-up / sleep: Dual rings can be used as warning or error verification.

[0025] Compared to existing technologies, the advantages of this invention are as follows: This invention provides a setting and reporting mechanism for wireless local area devices, solving the high complexity and cost associated with the deployment and repair of wired devices. Wireless devices do not require fiber optic or copper wires as signal transmission media, only power lines. Since most devices have built-in power distribution circuitry, reasonable voltage drop or fluctuations in the power lines remain within acceptable limits, significantly increasing the compatibility of wireless devices.

[0026] Through polling and automatic reporting (schedule), the server can remotely monitor the status (working / sleep / failed) and environmental information of each device. Most of the time, when reporting is not required, devices can be in sleep mode, reducing power consumption and increasing battery life for battery-powered devices. Furthermore, the dual-ring design (which can be directional) allows the systems to operate independently. When an invalid or warning state occurs, they can act as verifiers for each other, confirming the need for repairs or initiating emergency measures, reducing the risks during repairs and the preparation time for emergency response.

It includes the ability to set activation or sleep schedules; maintain operation only during preset activation times or in abnormal situations; enter sleep mode in other situations (maintaining the base clock, network information, and remote wake-up support); and detect oxygen or carbon monoxide, hazardous gases, dust, and temperature and humidity.

[0032] Furthermore, link a: by M AP ax Composed of, through wireless networking; link b is M AP bx It consists of a wireless network; link a and link b can serve as backups for each other.

[0033] Furthermore, the link can be extended at its end to accommodate more devices; any node in the link can be programmed into another new network, such as M. AP ax Programming as M AP axx If the new network is configured with different environmental conditions, it can be replaced with different communication protocols.

[0034] Furthermore, this embodiment includes a dual-ring design: separate small-area coverage to overcome wireless communication barriers in large areas; low repair costs and easy expansion; arbitrarily small-area networking with hybrid communication capabilities; and dual-ring design to ensure link reliability.

[0035] Furthermore, this embodiment includes Scheme 1:

[0036] Step 1: The server issues instructions to link a and link b respectively according to the schedule, requesting them to work (this process takes link a as an example).

[0037] Step 2: M AP_a1 After receiving the instruction, the system records the environmental information of the covered area and sends the work instruction along with the collected environmental information to M. AP_a2 transfer;

[0038] Step 3: M AP_a2 Received M AP_a1 After receiving the instruction, record the environmental information covered, along with M. AP_a1 Information and work instructions were sent to M together AP_a3 transfer;

[0039] Step 4: Continue the same process as above until the end, where M is located. AP_a9 ;

[0040] Step 5: The end device has a flyback function, which sends the environmental information it covers, along with the information it receives, to the previous level, for example, M. AP_a9 → M AP_a8 After completion, the device enters sleep mode;

[0041] a) If a device fails on the link, such as a timer / MA P_a4 → M AP_a5 M AP_a5 Not working or unresponsive, M AP_a4 The information is published to nearby backup link devices, such as M. AP_b7 ;

[0042] b) M AP_b7 In addition to carrying its own link b information, it also carries M. AP_a4 Published link a information;

[0043] Step 6: M AP_a8 If the environmental information is updated (within the allowable error or range of change), it can be overwritten or maintained and sent to the previous level. After completion, the device enters sleep mode.

[0044] a) If environmental information changes to values ​​higher than the default value (e.g., oxygen concentration too low / carbon monoxide too high, hazardous gas concentration / dust density too high), an alert will be issued;

[0045] b) As above, the device will also issue warnings to nearby backup link devices;

[0046] Step 7: Repeat the above steps until the server receives the information returned by the device, completing this round of work, and record, interpret, and transmit the received information to a higher-level server (if any).

[0047] a) If incomplete link information is received, repair can be arranged according to the marked location;

[0048] b) If an alarm signal is received, it can be reconfirmed through the backup link: if the signal is correct, emergency measures can be initiated; if the signal is suspected to be a misjudgment, the server can choose to read it again for confirmation and arrange for repair.

[0049] Step 8: Conditions for selecting the location of the device:

[0050] a) Meets the receiving sensitivity of ≥-74dBm with the upstream / downstream and nearby backup link devices; based on the minimum requirements of the data stream plus additional link margin;

[0056] Link a: Composed of MAP_ax, connected via wireless networking, location is known by default; Link b: Composed of MAP_bx, connected via wireless networking, location is known by default; Link a and Link b can serve as backups for each other; Links can be equipped with more devices, location is known by default;

[0057] Dual-ring design: separate small-area coverage to overcome wireless communication obstacles in large areas; low repair cost and easy expansion; dual rings ensure link reliability.

[0058] Furthermore, when deploying devices on links a and b, wake-up times can be set (they are in sleep mode the rest of the time); wake-up and working times can rotate daily or on a preset cycle; according to the timing table, the server can receive information from the corresponding devices during the set time period (this process uses link a as an example); the timing table period is the same as the period set for the devices on the link; M AP_a1 At a set time t1, the system resumes from sleep mode to normal operation mode, records environmental information for the covered area, and sends it. After sending, it enters sleep mode again. Similarly, M... AP_a2 to M AP_a9 Similarly, M AP_b1 to M AP_b9 The above actions will continue until the end of this round's schedule, completing the work for that round. The collected information will be recorded, interpreted, and transmitted to a higher-level server (if any). If any device is unresponsive or erroneous, repairs can be arranged according to the marked location. If an alarm signal is received, it can be reconfirmed via a backup link: if the alarm signal is correct, emergency measures will be initiated; if a suspected misjudgment signal is received, the server can choose to read it again for confirmation and arrange repairs.
