The invention belongs to the technical field of wireless monitoring, and relates to a wireless monitoring device for underground conditions. The main structure includes two functional parts: a monitoring unit and a data processing terminal. The monitoring unit and the data processing terminal are connected through wireless communication. Sleeve, intermediate nipple, first through hole, second through hole, upper protective sleeve, centralizer, internal thread, sensor module, circuit module, battery module, cover, lower instrument barrel, upper instrument barrel, groove It is composed of a transmitting transducer and an auxiliary circuit module, and is used for downhole condition monitoring in oil and gas drilling and production, downhole condition monitoring in coal mine drilling and production, pile hole monitoring in pile foundation construction in construction engineering, and other drills used Underground condition monitoring in long-distance pole or pipe string operation; its structure is simple, its principle is scientific and reasonable, its operability is strong, its use environment is friendly, its versatility is strong, and it is easy to popularize and use.

The invention discloses a vehicle-mounted built-in TF map data updating circuit and method. The method comprises: receiving a navigation map data updating instruction triggered by a liquid crystal display screen, controlling the liquid crystal display screen to pop up a password input window to receive password input; determining whether password entry is correct, if the entered password is correct, a general I / O port of the CPU microprocessor is controlled to output a high level; the interiors of the first high-speed USB analog switch and the second high-speed USB analog switch are simultaneously switched to a USB data end to be communicated with a second multiplexing source input end; wherein the TF card interface circuit is directly switched to the USB interface to wait for being connected with a user terminal for map upgrading, and if the input password is wrong, the GPIO0 of the CPU microprocessor is kept in a low-level state, and the first high-speed USB analog switch and the second high-speed USB analog switch are kept in a default state. The method can be applied to equipment with a vehicle-mounted navigation display screen with a built-in TF map card, and has the advantages of low cost, convenience for updating vehicle-mounted navigation map data at any time and the like.

The present invention relates to a multi-sensor combination-based fast tumble detection system. The system comprises a human body acceleration detection unit (104), a foot bottom pressure detection unit (105), a computing unit (101), a remote communication unit (102), a positioning unit (103), an interactive operation unit (106), a local alarm unit (107) and a main control unit (108); the human body acceleration detection unit (104) acquires an acceleration value during the movement process of a human body; the foot bottom pressure detection unit (105) detects the pressure value of the foot bottom of the human body; the computing unit (101) processes and judges the data acquired by the detection unit; the remote communication unit (102) realizes remote communication; the positioning unit (103) obtains location information and provides a positioning function; the interactive operation unit (106) provides a one-key help seeking function and a personalized man-machine interaction function; and the main control unit (107) controls the units and works in cooperation with the units. Compared with the prior art, the multi-sensor combination-based fast tumble detection system of the invention obtains more comprehensive and high-reliability information based on the body acceleration signals and foot bottom pressure signals. The interactive operation unit has the man-machine interaction function, and therefore, false alarm behaviors can be prevented, and autonomous help seeking can be performed.

A method for making bluetooth USB adapter have the man-machine interaction function (HID) is disclosed. With said method, a bluetooth USB adapter and a bluetooth keyboard or mouse can cooperate to implement an ordinary USB keyboard or mouse when compute is started. If the BIOS of computer does not support bluetooth function, the method can make user use bluetooth keyboard and mouse on starting.
