[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 obtain the physical addresses of N vehicle-mounted units 20 in a preset manner, and generate a list of physical addresses. Wherein, the preset method does not include the 5.8 GHz frequency band, and the physical address list includes the physical addresses of N vehicle-mounted units 20 , where N≥2, and N is a natural number.
[0022] The 5.8GHz read-write terminal 10 is also used to broadcast a wake-up signal to N vehicle-mounted units 20 through the 5.8GHz frequency band;
[0023] N vehicle-mounted units 20 are used to receive a wake-up signal and perform a wake-up operation; wherein, the channels of the N vehicle-mounted units 20 in the 5.8GHz frequency band are opened when leaving the factory;

Embodiment 2
[0041] This embodiment provides a method for issuing N vehicle-mounted units at one time, such as figure 2 As shown, the method includes:
[0042] Step S21, the 5.8GHz read-write terminal obtains the physical addresses of the N vehicle-mounted units in a preset manner, and generates a list of physical addresses;
[0043] Among them, the preset method does not include the 5.8GHz frequency band, and the physical address list includes the physical addresses of N vehicle-mounted units, where N≥2, and N is a natural number;
[0044] Step S22, the 5.8GHz read-write terminal sends a wake-up signal to the N vehicle-mounted units by broadcasting through the 5.8GHz frequency band;
[0045] Step S23, N vehicle-mounted units receive a wake-up signal, and perform a wake-up operation;
[0046] Among them, the channels of the 5.8GHz frequency band of the N vehicle-mounted units are turned on at the factory;
[0047] Step S24, the 5.8GHz read-write terminal establishes communication conne...

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, and the 5.8GHz read-write terminal is used to obtain the physical addresses of N vehicle-mounted units and generate physical addresses list; send wake-up signals to N vehicle-mounted units; N vehicle-mounted units are used to receive wake-up signals and perform wake-up operations; 5.8GHz read-write terminals are used to establish communication connections with N vehicle-mounted units in turn, and send to the i-th physical addresslist The vehicle-mounted unit corresponding to the physical address sends the i-th data. The i-th vehicle-mounted unit is used to receive the i-th data and process the i-th issued data; the 5.8GHz read-write terminal is also used to send the j-th confirmation data to the vehicle-mounted unit corresponding to the j-th physical address in the physical address list. The jth vehicle-mounted unit is used to receive the jth confirmation data, and send the jth confirmation response to the 5.8GHz read-write terminal. The 5.8GHz read-write terminal is also used to send a shutdown command to the vehicle-mounted unit corresponding to the jth physical address.
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;...
