The following describes the detailed implementation of the embodiments of the present invention with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.

"and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/", unless otherwise specified, generally indicates that the associated object is an "or" relationship. In addition, it should be understood that in the description of embodiments of the present invention, the words "first," "second," and the like are used merely for distinguishing between the descriptions and not be construed as indicating or implying a relative importance or order.
Referring to fig. 1, an embodiment of the present invention provides an elevator car wall plate, the car wall plate comprising: a car plate 10 provided on a side surface of an inside of the elevator car 20; a temperature-controlled semiconductor 30, one end of the temperature-controlled semiconductor 30 is connected with the car plate 10, the other end is connected with the conductive metal plate 40, and a cooling operation or a heating operation is performed when a current passes through the temperature-controlled semiconductor 30; a conductive metal plate 40 including a first metal plate 41 and a second metal plate 42, the first metal plate 41 being connected to a power source positive electrode 51 of a power source, the second metal plate 42 being connected to a power source negative electrode 52 of the power source for introducing a current of the power source positive electrode 51 to the power source negative electrode 52; the power supply 50 is electrically connected with the main control unit 60 and is used for switching between an on state and an off state based on a control instruction of the main control unit 60.
In one possible embodiment, the technician modifies the car plate 10 of the original elevator by providing a temperature-controlled semiconductor 30 on one side of the car plate, for example, the temperature-controlled semiconductor 30 may be disposed opposite the side of the car plate 10 that is located inside the car, one end of the temperature-controlled semiconductor 30 being connected to the car plate 10 and the other end being connected to the conductive metal plate 40, for example, in the embodiment of the invention, the conductive metal plate 40 includes a first metal plate 41 and a second metal plate 42, the first metal plate 41 being connected to the power supply positive electrode 51 of the power supply 50, and the second metal plate 42 being connected to the power supply negative electrode 52, thereby forming an electrical circuit.
In a specific implementation process, a technician may configure the temperature sensor 70 in the elevator car 20, and the elevator control system implements to acquire the temperature information in the elevator car acquired by the temperature sensor 70 during the elevator running process, and compares the temperature information with a preset temperature value in the elevator car 20 expected by the technician, for example, in the embodiment of the invention, the elevator control system determines that the current temperature in the elevator car 20 is greater than the preset temperature value in the elevator car after performing the temperature comparison, so as to produce a corresponding cooling control instruction.
In another possible implementation, in order to reduce energy consumption and to reduce frequent regulation of the temperature in the elevator car 20 by the elevator control system due to frequent changes in the ambient temperature, the technician sets the appropriate temperature in the elevator car 20 to a preset temperature control range, for example, 20-25 °, and the elevator control system determines that the current temperature in the elevator car 20 is less than the minimum value of the preset temperature control range by monitoring the temperature in the elevator car 20 in real time and determining whether the temperature information in the elevator car 20 is within the preset temperature control range during actual operation, for example, in the embodiment of the present invention, by determining that the current temperature in the elevator car 20 is less than the minimum value of the preset temperature control range, so that a corresponding temperature-raising control command is generated.
In the embodiment of the present invention, after generating the corresponding control command, the main control center 60 sends the control command to the power supply 50 to control the power supply 50 to be turned on or off. For example, in the embodiment of the present invention, after receiving the cooling control command, the power supply 50 is switched from the off state to the on state, and at this time, a current is output from the power supply positive electrode 51, and during the current flowing, the current passes through the temperature control semiconductor 30 via the first metal plate 41 in the conductive metal plate 40, and the temperature control semiconductor 30 cools the car plate 10 side and heats the conductive metal plate 40 side under the action of the current, so that the cooling operation is performed in the elevator car 20 by the car plate 10, and the temperature in the elevator car 20 is reduced.
At another moment, the elevator control system monitors that the current temperature in the elevator car 20 is within the preset temperature control range, so that a corresponding temperature control instruction is generated, for example, in the embodiment of the invention, a control instruction for stopping cooling is generated and sent to the power supply 50, and at this moment, the power supply is switched to be in a closed state, so that the temperature control operation of the elevator car 20 is completed.
In the embodiment of the invention, the traditional elevator car wall plate is improved, and the additional temperature control semiconductor 30 is configured for the traditional elevator car wall plate, so that the temperature control of the elevator car 20 is realized under the condition that no space of the elevator car roof is occupied, the temperature in the elevator car 20 is ensured to be at a comfortable temperature at any time, the activity space of technicians on the elevator car roof is effectively increased on the basis of ensuring the user experience of passengers in the elevator car 20, and the safety of the technicians in the working process is improved.

In one possible embodiment, the elevator control system controls the temperature in the elevator car 20 in real time via the main control unit 60 during use of the elevator. At a certain moment, a passenger carries a sharp weight into the elevator car 20, during the carrying process, the sharp weight breaks the insulating layer 12 on the car board 10, at this time, the main control unit 60 detects that the resistance of the conductive layer 122 is increased through the conductive layer 122 in the insulating layer 12, for example, in the embodiment of the invention, the main control unit 60 may first obtain a preset resistance value before the elevator runs, and compare the resistance value of the car board corresponding to the conductive layer 122 with the preset resistance value in real time during the actual running process, if the preset resistance value is smaller than the resistance value of the car board, it is determined that the car board 10 of the current elevator car 20 is broken, so in order to avoid the transmission of a power leakage condition, the main control unit 60 immediately transmits a corresponding safety control command to the power source 50, for example, in the embodiment of the invention, the power source 50 immediately cuts off the power supply to the temperature control semiconductor 30 after receiving the control command to stop the power supply, thereby realizing the safety protection of the passengers in the elevator.
In the embodiment of the invention, the insulating layer 12 is arranged on the car plate 10, and the integrity of the car plate 10 is monitored in real time through the conductive layer 122 in the insulating layer 12, so that once the car plate 10 is scratched by passengers, corresponding measures are immediately taken to ensure that the temperature control operation of the elevator car 20 does not cause electric shock hazard to the passengers, thereby greatly improving the safety of the elevator in the temperature control process.
