[0057] ​​​​​​​​​​

[0061] a plurality of data transmission channels corresponding to the temperature sensors, for transmitting real-time temperature analog signals collected by the corresponding temperature sensors to the signal conversion module.

[0062] It should be noted that the data transmission channel is three lines drawn from the temperature sensor body, specifically one 0V wire and two resistance wires.

[0063] a signal conversion module, for converting the real-time temperature analog signals into voltage-type digital signals; the voltage-type digital signals have an amplitude range of 0-10V.

[0065] a data register (CPU) in communication connection with the signal conversion module, for storing the voltage-type digital signals and sending them to the MCS escalator controller through RS485 serial communication mode;

[0066] In the embodiment, the purpose of storing the voltage-type digital signals is to provide assistance for subsequent fault analysis by providing them to escalator maintenance personnel for viewing in the later stage.

[0067] The MCS escalator controller is configured to select a preset speed control instruction according to the voltage-type digital signals and continuously output it to an escalator drive frequency converter.

[0068] The preset speed control instruction includes a first speed control instruction, a second speed control instruction, and a deceleration control instruction; the first speed in the first speed control instruction is greater than the second speed in the second speed control instruction.

[0069] The MCS escalator controller is further configured to set a first limit value range, a second limit value range, and a third limit value range corresponding to each temperature sensor, and a standard temperature voltage value corresponding thereto.

[0070] The first limit value range is greater than zero and less than or equal to a first preset warning value.

[0071] The second limit value range is greater than the first preset warning value and less than or equal to a second preset warning value.

[0072] The third limit value range is greater than the second preset warning value.

[0073] The first preset warning value = the standard temperature voltage value * 10%.

[0076] The application obtains the voltage type digital signal corresponding to the temperature sensor through the intelligent linkage control device of the escalator, and sends it to the MCS escalator controller. The MCS escalator controller selects the preset speed control instruction corresponding to the voltage type digital signal by using the preset judgment process, and continuously outputs it to the escalator drive frequency converter. The running speed of the motor in the motor module is controlled by the escalator drive frequency converter using the preset speed control instruction. The application controls the speed of the escalator based on the acquisition signal of the temperature sensor, and realizes the linkage control of the sensor and the escalator.

[0077] It should be noted that when the escalator is a double drive module, the drive host includes a first drive host and a second drive host; the first drive host and the second drive host each include a motor module; when the escalator is a double drive module, the temperature sensor module includes:

[0082] S01: acquiring the real-time temperature analog signal of the escalator running through the temperature sensor module;

[0083] S02: obtaining the voltage type digital signal corresponding to the real-time temperature analog signal through the signal conversion module;

[0084] S03: selecting the preset speed control instruction corresponding to the voltage type digital signal by using the preset judgment process of the MCS escalator controller, and continuously outputting it to the escalator drive frequency converter;

[0088] It needs to be explained that when it is within the first preset limit value range, the running speed is reduced by selecting the first speed control instruction to reduce the handrail belt running blockage problem, and the effect of motor heat dissipation is improved.

[0089] S33: Determine whether the temperature-voltage difference value is within its corresponding second preset limit value range, if yes, select the second speed control instruction and continuously output to the escalator drive frequency converter, jump to step S04; if not, proceed to the next step.

[0090] When it is within the second preset limit value range, the running speed is further reduced by selecting the second speed control instruction to reduce the handrail belt running blockage problem, and the effect of motor heat dissipation is further improved.

[0091] S34: Determine whether the temperature-voltage difference value is within its corresponding third preset limit value range, if yes, select the speed reduction control instruction and continuously output to the escalator drive frequency converter, and proceed to the next step.

[0093] Control to stop outputting the speed reduction control instruction to the escalator drive frequency converter after outputting for a preset time (10 seconds) to control the escalator to stop running. The purpose is that if the escalator stops immediately, the risk of passenger falling will be increased due to inertia problem, so the escalator is stopped immediately in emergency, and the running mode of slowing down first and then stopping is adopted in other cases.

[0094] The S04 step specifically includes: controlling the running speed of the motor in the motor module by the escalator drive frequency converter using the preset speed control instruction to realize the speed control of the escalator; the preset speed control instruction is the first speed control instruction or the second speed control instruction or the speed reduction control instruction.

[0095] The application sets multiple data transmission channels in the escalator intelligent linkage control device, the data transmission channels correspond to the temperature sensors one by one, in addition, the MCS escalator controller is further used for setting the first limit value range, the second limit value range and the third limit value range corresponding to each temperature sensor and the corresponding standard temperature voltage value; the corresponding limit value range and the standard temperature voltage value are set for different temperature sensors respectively, so that the judgment of the corresponding limit value range is carried out on different voltage type digital signals in the preset judgment process, therefore, the application realizes the flexible control of the escalator speed based on the collected signals of each temperature sensor.
