specific Embodiment 1

[0027] Specific embodiment 1: the coal mine underground personnel position detection substation of the present invention, such as figure 1 As shown, the present invention regards the detection substation as a device that actively acquires the card number. The detection substation and the identification card 7 first use a low-frequency signal to perform a "handshake" before establishing communication. When it is confirmed that both parties can realize high-frequency signal communication, Then the detection substation sends a card opening instruction to the identification card 7 within a certain time slot, so that the identification card 7 sends out the card number information with a high-frequency signal. Instruction, the identification card 7 continues to send card number information until the detection substation confirms that the information is correct and completes the card reading, and then sends a checkpoint command to the identification card 7, so that the identification ...

specific Embodiment 2

[0028] Specific embodiment 2: the present invention can at first preset the identification card information card number range, then assign a card-reading time slot for the identification card 7 in each range within the fixed round-robin time, detect the substation to identify in this time slot The card 7 sends a card opening command, and at the same time receives the information of the designated identification card 7, and after confirming that the card reading is completed, it sends a checkpoint command to the identification card 7, so that the identification card 7 enters a dormant state and no longer sends redundant data to the detection substation. The retrieved identification card information will no longer be sent repeatedly, reducing the storage and processing pressure of the detection sub-station, and preventing a large amount of redundant data from causing information conflicts on the identification card 7, resulting in missed reading and misreading. On this basis, the...

specific Embodiment 3

[0029]Specific embodiment 3: the present invention sends data to the host computer 10 in a round-robin manner, and when the detection substation reads the information of the identification card 7, it first performs storage processing, puts the information in the memory 2 and waits for the host computer 10 to read it, and the host computer 10 reads the information. The computer 10 sends reading instructions one by one according to the number of detection substations preset by the software. When the detection substation receives the instruction from the upper computer 10, it sends the currently stored data to the upper computer 10. After the upper computer 10 confirms that the data is correct and stores it Send an instruction that the information of the identification card has been correctly read to the detection substation, and the detection substation deletes the stored information that has been correctly read after receiving the confirmation instruction. Do the same for the ne...

Abstract

The invention relates to a substation for detecting the position of a coal mine underground person, which comprises a central processing unit, wherein the central processing unit is connected with a low-frequency signal transmitting module and a low-frequency signal receiving module; the low-frequency signal transmitting module is used for covering a card reading area with a 315MHz low-frequency signal, and an identifying card listens to a command of the detecting substation every four seconds; the low-frequency signal receiving module is used for receiving the low-frequency signal which is transmitted to the detecting substation by the identifying card entering the card reading area; the central processing unit is also connected with a high-frequency signal transmitting module and a high-frequency signal receiving module; the high-frequency signal transmitting module is used for transmitting a high-frequency signal with the size of 2.4G to the identifying card entering the card reading area; the high-frequency signal receiving module is used for receiving the high-frequency signal which is transmitted to the detecting substation by the identifying card; the central processing unit is used for verifying and confirming the number of the identifying card and also is connected with a memory for storing information which is transmitted to the detecting substation by the identifying card. The detecting substation can effectively monitor the position of an underground person.

Description

technical field [0001] The invention relates to a personnel position detection station, in particular to a mining equipment using radio frequency technology to realize identification (RFID), which can be used for checking attendance, position detection and identification in dangerous operating environments such as coal mines. The invention belongs to the technical field of coal mine personnel safety management measures. Background technique [0002] Coal mine construction safety and personnel management are a top priority for coal mine workers, especially coal mine managers. The position, area, and number of coal mining workers in the mine must be well known to managers. In recent years, accidents in coal mines have been frequent, and most of the accident coal mines first encountered the two major problems of counting the number of people trapped underground and counting the location and area of ​​the trapped people when implementing rescue. [0003] In order to solve the i...
