Embodiment 1

[0074] Embodiment 1 of the present invention discloses a wireless access point AP, the AP corresponds to unique first identification information, please refer to figure 1 , the AP includes a wireless transceiver module 101 and a visible light receiving module 102 .

[0075] The wireless transceiver module 101 is configured to transmit and receive data by radio.

[0076] Wherein, the function of the wireless transceiver module 101 can specifically be realized by using a Wi-Fi (Wireless High Fidelity) transceiver module or a wireless base station.

[0077] The visible light receiving module 102 is configured to receive data in a visible light communication manner.

[0078] The visible light receiving module 102 includes K PDs (Photo Diodes, photodiodes), each PD corresponds to unique second identification information, and K is a natural number greater than 1.

[0079] In order to provide support for subsequent various business processes, this embodiment assigns a unique networ...

Embodiment 2

[0083] Embodiment 2 discloses a communication system, such as figure 2 As shown, the communication system includes the AP 100 disclosed in Embodiment 1 and N terminals 200 , the terminals 200 and the AP 100 communicate with each other, and also include a data processing module 300 .

[0084] The communication system of the present invention can support the data transmission requirements of comprehensive services such as personnel positioning service, video return service, sensor monitoring data return service and alarm service.

[0085] Wherein, the terminal 200 includes a visible light mobile terminal and an environment sensor terminal, and the visible light mobile terminal corresponds to unique third identification information. .

[0086] like image 3 As shown, the visible light mobile terminal includes a first Wi-Fi transceiver 301 , a first visible light emitting device 302 , a camera 303 and a first environment sensor 304 . Among them, the first Wi-Fi transceiver 301...

Embodiment 3

[0104] Embodiment 3 of the present invention supplements the communication system of Embodiment 2. Specifically, in this embodiment, the first Wi-Fi transceiver included in the visible light mobile terminal is also used to maintain the location information of the places that the visible light mobile terminal frequently visits and frequency information to reach the location, and broadcast the location information and frequency information.

[0105] In scenarios such as mine side roadways and mining faces, there are no lighting power lines or only limited lighting power lines, and the environment in this scene is harsh, the roadway is uneven, and landslides occur from time to time, which makes cable layout very inconvenient. Wi- The Fi base station is also not easy to install. Therefore, in this scenario, the visible light mobile terminal cannot directly access the central AP to report its service data. To solve this problem, in this embodiment, the visible light mobile terminal ...

Abstract

The invention discloses a communication system and method. The system comprises an AP, N terminals and a data processing module, wherein the AP comprises a wireless receiving and sending module and a visible light receiving module, and the AP provides covering of two communication signals of wireless and visible light for an under-mine terminal through the two modules. According to the communication method, when the terminals receive request information of the AP, service data are sent to the AP by correspondingly adopting the wireless mode or the visible light communication mode or simultaneously adopting the wireless and visible communication modes according to light and electric channel states, subsequently, the AP adds corresponding identification information to the server data, then the service data are reported to the data processing module, and the data processing module performs corresponding service processing on the service data. Thus, when one communication link is disconnected or the signals are weak, the other link is adopted for achieving time transmission of the service data, and the problem that in the existing single-communication mode, due to the fact that the communication link is disconnected, it cannot be ensured that the service data are uploaded in time is solved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to an AP (Access Point, wireless access point), a communication system and a communication method. Background technique [0002] The working environment under the mine is complex and harsh, and the gas concentration is high, which is prone to danger. Therefore, it is necessary to know the environmental conditions and staff information under the mine at any time, so as to facilitate the follow-up work of safety prevention and control, dispatching and control under the mine. Based on this, the underground communication system, which undertakes the function of underground business data transmission, has become an essential system for underground operations. [0003] At present, the underground communication system adopts a single communication mode. For example, Henan Feiguang Communication Technology Co., Ltd. proposed a mine communication system based on 3...
