the system comprises a thread creating module, a thread setting module and a thread selecting module, wherein the thread creating module is used for creating a first thread and simultaneously creating a second thread and/or a third thread, the first thread is a gateway control thread, the second thread is an environment monitoring thread, and the third thread is an alarm monitoring thread;
the acquisition module is used for acquiring instruction information of the client, and the instruction information further comprises an environment monitoring instruction and/or an alarm monitoring instruction;
the judging module is used for judging whether the state of the network port is normal or not in the first thread;
the mapping module is used for mapping the instruction information to the second thread and/or the third thread respectively based on a preset message mapping mechanism if the instruction information is normal;
the first sending module is used for sending the environment monitoring instruction to the environment monitoring module in the second thread to generate an environment monitoring result, and/or sending the alarm monitoring instruction to the alarm monitoring module in the third thread to generate an alarm monitoring result;
the second sending module is used for obtaining the environment monitoring result and/or the alarm monitoring result and sending the environment monitoring result and/or the alarm monitoring result to the client;
the first thread is also used for responding to, controlling and adjusting the working parameters of the camera.
8. The camera system multi-thread control device of claim 7, wherein the first transmitting module further comprises:
the first sending unit is used for sending the environment monitoring instruction to the environment monitoring module in the second thread;
a first timing unit to create a first timer at the second thread, the first timer comprising a first timing period;
the first triggering unit is used for periodically triggering the environment monitoring module based on a first timing period so as to obtain one or more environment monitoring results.
9. A server comprising a memory, a processor and a program stored on the memory and executable on the processor, wherein the processor implements a camera system multithreading method as recited in any one of claims 1 to 6 when executing the program.
10. A terminal readable storage medium on which a program is stored, the program being capable of implementing a camera system multithread control method according to any one of claims 1 to 6 when executed by a processor.
