[0032] In an embodiment, the access control system 11 further comprises an identity recognition module 103 connected with the access control module 101.

[0033] The identity recognition module 103 is configured to collect and recognize user identity information of a user, and send the user identity information to the access control module 101.

[0034] The access control module 101 is configured to determine a target access control permission of the user based on the user identity information and a preset mapping relationship between user identity information and access control permissions, and determine an access control instruction of the switch control module 102 based on the target access control permission and a target access control mode, so as to control the opening and / or closing of the tank door by the switch control module 102 based on the access control instruction.

[0035] The identity recognition module 103 can include at least one of a magnetic card recognition module, a face recognition module, a fingerprint recognition module, and an iris recognition module.

[0067] The intelligent fire monitoring camera is provided with an intelligent image recognition module, which can identify whether there is smoke, open fire or the like inside the energy storage system 10.

[0068] In some embodiments, each fire detection module 202 is provided with a three-level early warning threshold, as follows:

[0069] Combustible gas detector: first level early warning: CO, 50ppm, H2, 100ppm, second level early warning: CO, 190ppm, H2, 300ppm, third level early warning: CO, 300ppm, H2, 1000ppm;
