Command analysis module is parsed for receiving coincidence counting instruction, and to coincidence counting instruction, is obtained corresponding
The channel data of destination channel combination, wherein the channel data of destination channel combination includes the target master for participating in coincidence counting
Channel number of the channel number and target in channel from channel；
Label chooses module, for according to the channel number that gets from the time tag data of each signal path of storage,
Choose time tag data corresponding with the channel number；
Count execution module, the time tag of the time tag data and target of the target main channel for that will choose from channel
Data carry out coincidence counting comparison, obtain coincidence counting result corresponding with coincidence counting instruction.
9. device according to claim 8, which is characterized in that it is corresponding that the coincidence counting equipment is stored with each signal path
Preset time window width, the counting execution module includes:
Time compares submodule, for calculating the target from the time tag data in channel and the time of the target main channel
Signal between label data generates the time difference, and calculated each target signal corresponding to the channel is generated the time difference and institute
The preset time window width for stating target main channel is compared；
Decision sub-module is counted, for wide no more than the preset time window when each calculated signal generation time difference
When spending, one is added from the coincidence counting result between channel to the target main channel and other described targets.
10. device according to claim 9, which is characterized in that described device further include:
Window configuration module, for carrying out configuration storage to the corresponding preset time window width of each signal path.
