1. A grease injection system, comprising:
a plurality of grease injection devices, each comprising:
a grease injection element;
a grease injection communication element configured to receive control information; and
a grease injection control element coupled to the grease injection element and the grease injection communication element and configured to control the grease injection element with control information to output lubricating grease, detect an operational status of the grease injection element to provide status information, and control the grease injection communication element to output the status information; and
a host configured to communicate bidirectionally with the grease injection devices, so as to receive a plurality of pieces of status information from the grease injection devices, and generate a plurality of corresponding pieces of control information based on the pieces of status information,
wherein a communication range of a first grease injection device of the grease injection devices covers communication ranges of the host and a second grease injection device of the grease injection devices, and
the first grease injection device forwards control information from the host to the second grease injection device, and forwards status information of the second grease injection device to the host.
