In implementation, the elevator drives the on feedback unit 141 to do lifting motion, the on feedback unit 141 tries to establish communication connection with each adjacent ground mesh router 11 in the lifting process, in the process of establishing communication connection, whether communication signals exist between the on feedback unit 141 and the corresponding ground mesh router 11 or not is tested, if the communication signals exist, the signal intensity of the communication signals is continuously tested to obtain signal intensity data, and meanwhile, the communication rate of the communication signals is tested to obtain communication rate data; then, the feedback unit 141 is connected to send the obtained communication signal, signal intensity data and communication rate data to the feedback signal processing unit 142 through the ground mesh router 11 and the ground mesh gateway 12, and then the feedback signal processing unit 142 judges whether the communication signal exists or not, whether the signal intensity data is larger than a preset signal intensity threshold value or not and whether the communication rate data is larger than a preset communication rate threshold value or not, so that a corresponding judgment result is obtained; and then the judgment result is sent to the operation and maintenance processing unit 143 for processing, if the operation and maintenance processing unit 143 confirms that the judgment result has one or more of no communication signal, no signal intensity data greater than a preset signal intensity threshold and no communication rate data greater than a preset communication rate threshold, the operation and maintenance processing unit 143 immediately sends corresponding operation and maintenance processing information to the maintenance intelligent terminal, wherein the operation and maintenance processing information comprises corresponding on-ground mesh router 11 information and corresponding judgment results, so that operation and maintenance personnel can maintain the corresponding on-ground mesh router 11 according to the on-ground mesh router 11 information and the corresponding judgment results in time, and the operation stability of the mesh network is improved.
It should be noted that, along with the continuous promotion of the carbon neutralization plan in China, the method of energy conservation and emission reduction goes deep into various industries; it should be noted that, only in the process of elevator manned operation, the wireless signal emitted by the above-ground mesh router 11 has a use meaning, and in the process of elevator suspension operation, the above-ground mesh router 11 is still in the working state of emitting the wireless signal, which is obviously a way of wasting electric energy.
In one embodiment, in order to facilitate energy saving of the above-ground mesh network 1, referring to fig. 4, the above-ground mesh network 1 further includes a first energy saving component 15 connected to the above-ground mesh router 11, specifically, the first energy saving component 15 includes a logic controller 151 communicatively connected to an elevator control system, where the elevator control system is configured to implement transportation of people between different floors according to physical interaction with people, and the elevator control system generates corresponding transportation information during the physical interaction with people, where the transportation information includes floor information where people are currently located and destination arrival floor information; the logic controller 151 is electrically connected to a switching signal transmitter 152. Each ground mesh router 11 is connected with a remote switch 153, and the switch signal transmitter 152 is used for generating a remote control signal for controlling the remote switch 153 to be opened and closed; each remote control switch 153 is electrically connected to a router power supply 154 for supplying power to the corresponding mesh router 11.
In implementation, once a person performs physical interaction with the elevator control system, the elevator control system generates corresponding transfer information, and then sends the corresponding transfer information to the logic controller 151, and the logic controller 151 analyzes the transfer information to determine the above-ground mesh router 11 corresponding to the transfer information, where it should be noted that the signal coverage of the above-ground mesh router 11 determined by the logic controller 151 may cover the elevator shaft space range from the current floor to the destination arrival floor.
For example, assuming that the current floor is 1 floor and the destination floor is 5 floors, in order that the signal coverage of the above-ground mesh router 11 can cover the hoistway space range between the current floor and the destination floor, the above-ground mesh router 11 determined by the logic controller 151 includes the above-ground mesh router 11 located at the first floor, the third floor and the fifth floor, so that the coverage of the wireless signal in the hoistway space range between the 1 floor and the 5 floors can be achieved.
After the corresponding ground mesh router 11 is determined, the logic controller 151 transmits a remote control signal to the remote control switch 153 connected to the determined ground mesh router 11 through the switch signal transmitter 152, so that the corresponding ground mesh router 11 is in an electrical connection state with the corresponding router power supply 154; while controlling the rest of the above-ground mesh routers 11 to be in a power-off state. It should be noted that, when the logic controller 151 does not receive the transfer information sent by the elevator control system for a preset time interval, all the ground mesh routers 11 are remotely controlled to be in the power-off state; in this way, the corresponding ground mesh router 11 can be started under the situation that the ground mesh router 11 is required to be used, and the corresponding ground mesh router 11 can be stopped under the situation that the ground mesh router 11 is not required to be used, so that the energy saving of the ground mesh network 1 is convenient to realize.

In practice, the noise generated when people pass through the corridor can control the sound control switch 161 to establish electrical connection between the signal amplifier power supply 163 and the corresponding wifi signal amplifier 13, so that the signal amplifier power supply 163 supplies power to the corresponding wifi signal amplifier 13; when people pass through the corridor, the human body infrared induction switch 162 senses that the human body also establishes electric connection between the signal amplifier power supply 163 and the corresponding wifi signal amplifier 13, so that the signal amplifier power supply 163 supplies power to the corresponding wifi signal amplifier 13; in addition, when people are only in the corridor but temporarily do not make noise, at this time, although the voice control switch 161 does not establish the electrical connection between the signal amplifier power supply 163 and the corresponding wifi signal amplifier 13 any more, since the human body infrared sensing switch 162 senses the human body, the human body infrared sensing switch 162 also establishes the electrical connection between the signal amplifier power supply 163 and the corresponding wifi signal amplifier 13 any more, so that the signal amplifier power supply 163 supplies power to the corresponding wifi signal amplifier 13. When people leave the corresponding corridor, the voice control switch 161 and the human body infrared induction switch 162 do not establish electrical connection between the signal amplifier power supply 163 and the corresponding wifi signal amplifier 13 any more, so that the signal amplifier power supply 163 does not supply power to the corresponding wifi signal amplifier 13 any more, and the wifi signal amplifier 13 is in a power failure stop state at the moment; therefore, the corresponding wifi signal amplifier 13 only works when a person is in a corridor, so that energy conservation of the mesh network is further facilitated.
It should be noted that, in the implementation, a plurality of communication areas are previously divided in the underground garage according to the signal coverage of the mesh router.

It should be noted that, due to the moisture in the environment of the underground garage, the underground mesh router 22 often fails, so that the operation stability of the underground mesh network 2 is not good.
In one embodiment, in order to facilitate improving the operation stability of the underground mesh network 2, the underground mesh network 2 further includes a plurality of converters 23 communicatively connected to the underground mesh gateway 21, the plurality of converters 23 are in one-to-one correspondence with the plurality of communication areas, each converter 23 is connected with not only the above-mentioned underground mesh router 22 but also a standby underground mesh router 24, and the converters 23 are used for switching the connection with the underground mesh router 22 or with the standby underground mesh router 24; the underground mesh gateway 21 is also communicatively connected with a routing signal judger 25, the routing signal judger 25 is used for receiving and judging the operation signal sent by the underground mesh router 22 at regular time, and the routing signal judger 25 is also communicatively connected with the converter 23 and is used for controlling the converter 23 to switch the connection with the underground mesh router 22 or with the standby underground mesh router 24.
