Problems solved by technology

[0002] In the prior art, when the 5.8GHz read-write terminal executes operations such as the issuance, activation, system upgrade, and warehouse management of the vehicle-mounted unit, it needs to perform one-to-one operations on the vehicle-mounted unit, and since the 5.8GHz read-write terminal and the data of the vehicle-mounted unit There is a big difference between the time required for transmission and the time required for data processing by the on-board unit. The resulting time difference causes the 5.8GHz read-write terminal to take too long to perform the above operations and inefficiency

Embodiment 1

[0020] The present embodiment provides a system for distributing N vehicle-mounted units 20 at one time, such as figure 1 As shown, the system includes a 5.8GHz read-write terminal 10 and N vehicle-mounted units 20 .

[0021] The 5.8GHz read-write terminal 10 is used to broadcast a wake-up signal to N vehicle-mounted units 20 through the 5.8GHz frequency band; wherein, N≥2, and N is a natural number;

[0022] N vehicle-mounted units 20 are used to receive a wake-up signal, and switch the sleep state of the 5.8GHz frequency band to the working state of the 5.8GHz frequency band; wherein, the sleep state of the 5.8GHz frequency band of the N vehicle-mounted units 20 is set when leaving the factory;

[0023]The 5.8GHz read-write terminal 10 is also used to obtain the physical address of a preset vehicle-mounted unit 20 in the N vehicle-mounted units 20 by scanning the two-dimensional code, and communicate with the physical address of the preset vehicle-mounted unit 20 through the...

Embodiment 2

[0042] This embodiment provides a method for issuing N vehicle-mounted units at one time, such as figure 2 As shown, the method includes:

[0043] Step S21, the 5.8GHz read-write terminal sends a wake-up signal to N vehicle-mounted units by broadcasting through the 5.8GHz frequency band;

[0044] Among them, N≥2, and N is a natural number;

[0045] Step S22, N vehicle-mounted units receive a wake-up signal, and switch the dormant state of the 5.8GHz frequency band to the working state of the 5.8GHz frequency band;

[0046] Among them, the sleep state of the 5.8GHz frequency band of the N vehicle-mounted units is set at the factory;

[0047] Step S23, the 5.8GHz read-write terminal obtains the physical address of a preset vehicle-mounted unit among the N vehicle-mounted units by scanning the two-dimensional code, and establishes with the preset vehicle-mounted unit through the 5.8GHz frequency band according to the physical address of the preset vehicle-mounted unit communi...

Abstract

The invention provides a system and method for issuing N vehicle-mounted units at one time. The system includes a 5.8GHz read-write terminal and N vehicle-mounted units. The 5.8GHz read-write terminal sends wake-up signals to N vehicle-mounted units through the 5.8GHz frequency band, and N A vehicle-mounted unit is used to receive the wake-up signal, and switch the dormant state of the 5.8GHz frequency band to the working state of the 5.8GHz frequency band; the 5.8GHz read-write terminal obtains the physical address of a preset vehicle-mounted unit, and sends it to the preset vehicle-mounted unit through the 5.8GHz frequency band Obtain instructions; the preset vehicle unit receives the acquisition instructions, obtains the pre-stored information table, and sends the information table to the 5.8GHz read-write terminal through the 5.8GHz frequency band; the 5.8GHz read-write terminal passes through the 5.8GHz frequency band sequentially according to the physical address in the information table Establish a communication connection with the vehicle-mounted unit except the preset vehicle-mounted unit among the N vehicle-mounted units, and send the i-th data to the vehicle-mounted unit corresponding to the i-th physical address in the information table.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a system and method for issuing N vehicle-mounted units at one time. Background technique [0002] In the prior art, when the 5.8GHz read-write terminal executes operations such as the issuance, activation, system upgrade, and warehouse management of the vehicle-mounted unit, it needs to perform one-to-one operations on the vehicle-mounted unit, and since the 5.8GHz read-write terminal and the data of the vehicle-mounted unit There is a big difference between the time required for transmission and the time required for data processing by the on-board unit. The resulting time difference causes the 5.8GHz read-write terminal to take too long and inefficient to perform the above operations. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a system for issuing N vehicle-mounted units at one time;...
