According to one aspect of the disclosure, an apparatus for synchronizing time of a communication or/and positioning terminal, includes: time calibration and transmission module, terminal and line.

The time calibration and transmission module is a module capable of transmitting time calibration information to a connected terminal through a line.

The terminal is a module which is connected with the time calibration and transmission module through a line and can receive and process time information.

The line is a wired network connecting the time calibration and transmission module and the terminal.

Preferably, as an alternative embodiment, the line may be a separate line to directly connect the time calibration to the transmitting module and the terminal, so as to ensure that the intermediate link and the intermediate interference are reduced.

Preferably, the time calibration and transmission module may assist in determining a delay time of a line to which each terminal is connected, that is, a time of receiving a network message between the time calibration and transmission module and each terminal.

Preferably, the time calibration and transmission module may store the network addresses of the terminal and the calibration and transmission module at other times so as to transmit information.

Preferably, the terminal may store the calibration and transmission module and the network address of the terminal at other times to facilitate transmission of information.

Preferably, the time calibration and transmission module may have identification information for transmitting a message identifying itself in the message.

According to one aspect of the disclosure, a method for synchronizing time of a communication or/and positioning terminal is characterized by comprising:

obtaining the communication time between each terminal and the time calibration and transmission module of the terminal;

storing the communication time between each terminal and the time calibration and transmission module of the terminal and the time into the terminal;

the time calibration and sending module can send time calibration information at intervals, and the terminal adds the communication time value in the storage device to obtain the current time after receiving the time information sent by the time calibration and sending module.

Preferably, the time calibration message may include the time when the time calibration and transmission module transmits the message.

Preferably, the specific time interval of the interval of time may be a fraction of a second, may be several seconds, and may be several hours.

Preferably, as an alternative implementation manner, a feedback-needed message with a timestamp (time of sending) is sent to each terminal from the terminal calibration and sending module with the time, then each terminal receives the message and sends the message back to the terminal calibration and sending module without changing the message, after the terminal calibration and sending module receives the sent message, the time of the initial sending is analyzed from the message, the difference is compared with the current time in the time calibration and sending module, and then the difference is divided by 2 to be regarded as the time of one single-pass sending of the message, so as to be used as the communication time.

Further, the feedback required message with the time stamp (time when sending) and the time synchronization information are information of two message numbers.

Preferably, as an alternative implementation manner, a message with a timestamp (time at transmission) and needing feedback is sent from the terminal to the time calibration and sending module connected through a line, after the time calibration and sending module receives the message, the message is returned to the terminal, after the terminal receives the message, the terminal analyzes the time information in the message, then the time information is calculated with the current time of the terminal to obtain a time interval, the time interval information is divided by 2 to obtain a communication time value between the terminal and the time calibration and sending module, and the terminal can store the communication time value into a storage medium of the terminal.

Preferably, the communication time of each of the terminals may be stored in a storage medium of each of the terminals.

Preferably, when each terminal receives the calibration time message sent by the time calibration and sending module, the current time of the terminal is obtained by adding the communication time read from the storage medium of the terminal to the time information analyzed from the calibration time message.

Preferably, as an alternative implementation, the time synchronization information may be transmitted from the time calibration and transmission module to each terminal once at a certain time period of a certain day.

Preferably, as an optional implementation manner, the time calibration and transmission module may also be one or one terminal.

Further, in this case, a list file of target terminals sending the time synchronization message may be stored in the time alignment and sending module, and the list file may store to which connected terminals the time synchronization message needs to be sent.

Further, in this case, the communication time values (communication time interval information) of the calibration and transmission modules for all the times to which each terminal is connected may be stored in the terminal.

Further, such an embodiment arranges a plurality of said time calibration and transmission modules with respect to the topological mesh structure, and some of them also have the property of the terminal itself, i.e. being able to obtain a more accurate time from a certain said time calibration and transmission module to which it is connected.
