Accompanying drawing explanation
Fig. 1 is the theory diagram of whole system.
Fig. 2 is the schematic block circuit diagram of wireless data sending table.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment: seeing Fig. 1, Fig. 2, a kind of wireless data transmission system, including host computer, REPEATER DATA case and wireless number
Pass table.Wherein, REPEATER DATA case is multiple, and it includes switch and several repeater, described switch by Ethernet with
Host computer be connected, each repeater respectively with multiple wireless data sending table wireless connections, described wireless data sending table is respectively connected with sensor.
When being embodied as, 1 repeater and 4 wireless data sending tables are connected, so that structure more optimizes.The repeated device of wireless data sending table
It is connected with host computer afterwards such that it is able to guarantee the stability in data transfer, and can effectively reduce wireless data sending table
Power consumption.
Described wireless data sending table includes housing, pcb board, display screen, sensor connector, antenna and battery.Described sensing
Device joint and antenna are located on housing, are respectively arranged at two ends with upper cover body and lower cover up and down at housing.Described pcb board level sets
In housing, and near upper cover body；Described display screen is located between pcb board and upper cover body, and in upper cover body, corresponding display screen sets
There is transparent window.Being provided with a battery mounting below pcb board, described battery is installed on this battery mounting, and its length
