Embodiment 1
[0022] This embodiment provides a method for issuing N vehicle-mounted units at one time, such as figure 1 As shown, the method includes:
[0023] Step S101, the issuing terminal sends a wake-up signal to N vehicle-mounted units by broadcasting through the 5.8GHz frequency band;
[0024] Among them, N≥2, and N is a natural number;
[0025] Step S102, N vehicle-mounted units receive wake-up signals respectively, each vehicle-mounted unit switches the first state to the second state, and sends a wake-up response to the issuing terminal through the 5.8GHz frequency band;
[0026] Wherein, the first state is a state of receiving information only through the 5.8GHz frequency band without responding, and the second state is a state of receiving information through the 5.8GHz frequency band and responding to the received information;
[0027] Step S103, the issuing terminal extracts the physical address of the preset vehicle-mounted unit carried in the first wake-up response from t...
Embodiment 2
[0053] The present embodiment provides a system for distributing N vehicle-mounted units 20 at one time, such as figure 2 As shown, the system includes an issuing terminal 10 and N vehicle-mounted units 20 .
[0054] The issuing 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;
[0055] Each vehicle-mounted unit 20 is used to receive a wake-up signal, switch the first state to a second state, and send a wake-up response to the issuing terminal 10 through the 5.8GHz frequency band; wherein, the first state is to only receive information through the 5.8GHz frequency band without responding state, the second state is the state of receiving information through the 5.8GHz frequency band and responding to the received information;
[0056] The issuing terminal 10 is also used to extract the physical address of the preset vehicle-mounted unit 20 carried in the first wake-up res...
Embodiment 3
[0080] This embodiment provides an issuing terminal 10, such as image 3 As shown, the issuing terminal 10 includes:
[0081] The 5.8GHz frequency band communication module 11 is used to broadcast a wake-up signal to N vehicle-mounted units through the 5.8GHz frequency band; wherein, N≥2, and N is a natural number; receive a wake-up response, wherein the wake-up response is received by each vehicle-mounted unit The wake-up signal is sent through the 5.8GHz frequency band after switching the first state to the second state; among them, the first state is a state that only receives information through the 5.8GHz frequency band without responding, and the second state is that both receive through the 5.8GHz frequency band The status of the message responding to the received message;
[0082] An extracting module 12, configured to extract the physical address of the preset vehicle-mounted unit carried in the first wake-up response from the first wake-up response received;
