The hardware information includes the processor, memory, input device and output device. The hardware data interval value is the parameter interval value for normal operation. The identification, information and data interval value of the noise detector and vibration sensor are combined with the test equipment configuration to store information and form a database.
[0019] Example 2 As a preferred embodiment of the present invention: in the control module, the control module is a core module of the dynamic simulation system, which implements the network control algorithm, including call access control, switching management, wireless resource management and scheduling; The control module is the core module of the dynamic simulation system. It completes almost all network control algorithms, including call access control, switching management, wireless resource management and scheduling. For access control, the network control module extracts wireless link information from the service processing module, and then decides whether to access or block the wireless link request based on the wireless resource management strategy; for switching management, the network control module needs to detect the location change of the mobile station. If the location of the mobile station changes, it decides whether to switch the mobile station based on the switching algorithm, and adjusts the transmission power of the relevant base stations and mobile stations; for wireless resource management and scheduling, a variety of strategies and algorithms can be used, such as centralized control, distributed control or hybrid control algorithms. These algorithms mainly manage and schedule various physical resources, such as wireless channels, transmission power, frequency, time slots, code resources, etc., analyze and process the detection data, and control the remote maintenance and constant temperature treatment modules.
[0020] Example 3 As a preferred embodiment of the present invention: in current detection, the voltage, current, power and resistance of the hardware are detected; The electrical inspection of elevator drive equipment refers to the process of inspecting, testing and evaluating electrical equipment, power systems and electrical engineering. It mainly verifies the normal working state, performance indicators and safety and reliability of electrical equipment by measuring and analyzing the voltage, current, power, resistance, capacitance, inductance and other parameters of electrical equipment. Power system inspection refers to the inspection and evaluation of each link of the power system, including power generation, transmission, distribution and power consumption. In the power system inspection, it is necessary to measure and analyze the voltage, current, power factor, frequency and other parameters of the power system, and to detect the voltage, current and frequency of the generator set to ensure that the output power meets the requirements; the voltage drop, current load, insulation resistance and other tests of the transmission line are carried out to ensure the stability and safety of power transmission; the voltage, current and power factor of the distribution equipment are tested to ensure the rational and efficient distribution of power; the power, power factor and current of the power equipment are tested to ensure the rational use of power and energy saving and emission reduction. By testing the current and voltage of the elevator drive equipment, the normal operation of the equipment is effectively guaranteed.
[0021] Example 4 As a preferred embodiment of the present invention: in current detection, a voltmeter, an ammeter, a power tester and a resistance tester are used; Current detection can detect the current size in the circuit in real time. Once an abnormal situation occurs, such as current overload or short circuit, the system can immediately take emergency measures, such as power off or alarm, which can effectively avoid accidents and improve the safety of the circuit. Current detection can help us monitor the operating status and energy consumption of electrical appliances in real time, discover problems in time and take adjustment measures, such as replacing equipment with higher energy consumption or adjusting the working mode, so as to achieve the effect of reducing energy consumption. Abnormal situations such as current overload or short circuit will have adverse effects on the equipment and even cause equipment damage. Through current detection, problems can be discovered in time and measures to avoid damage can be taken. A voltmeter is an instrument for measuring voltage, which is composed of a permanent magnet, a coil, etc. An ammeter refers to an instrument used to measure current in AC and DC circuits. The ammeter is made based on the effect of magnetic field force on the current-carrying conductor in the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field, and there is a hairspring spring at each end of the coil. The spring is connected to a terminal of the ammeter. The spring and the coil are connected by a rotating shaft. There is a pointer at the front end of the rotating shaft relative to the ammeter. When current passes through, the current passes through the magnetic field along the spring and the rotating shaft. The current cuts the magnetic flux lines, so the coil is deflected by the magnetic field force, driving the rotating shaft and the pointer to deflect. Since the magnitude of the magnetic field force increases with the increase of current, the magnitude of the current can be observed by the degree of deflection of the pointer. A power tester is an electronic measuring instrument used in the field of electronics and communication technology, used to detect power. A resistance tester is an instrument for measuring the conductivity of an object, suitable for testing the contact resistance value of the main contacts of high and low voltage switches, the DC resistance value of high and low voltage cable lines, etc.
[0022] Example 5 As a preferred embodiment of the present invention: in the environmental detection, the environmental temperature is detected by a temperature sensor, the humidity is measured by a humidity sensor, and the air pressure in the well is detected by a pressure sensor; A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. The contact mode between the temperature sensor and the measured medium is divided into two categories: contact and non-contact. The contact temperature sensor needs to maintain thermal contact with the measured medium so that the two can fully exchange heat and reach the same temperature. This type of sensor mainly includes resistance, thermocouple, PN junction temperature sensor, etc. Non-contact temperature sensor does not need to contact with the measured medium, but is transmitted to the temperature sensor through the thermal radiation or convection of the measured medium to achieve the purpose of temperature measurement. This type of sensor mainly includes infrared temperature sensor. The main feature of this temperature measurement method is that it can measure the temperature of moving substances and objects with small heat capacity. The humidity sensor is used to measure the value of air humidity, and the pressure sensor is an instrument used to measure the absolute pressure of gas. The temperature sensor, humidity sensor and pressure sensor respectively detect the temperature, humidity and air pressure around the well and the elevator drive equipment. If the detected value exceeds the preset value, the control module controls the operation of the variable temperature structure, ventilation structure and drying structure of the constant temperature treatment.
[0023] Example 6 As a preferred embodiment of the present invention: in the environmental detection, the network signal in the well where the vibration noise active control system hardware is located should be detected to ensure that the network signal always maintains high speed; Use network signal detection equipment to detect the signal in the shaft. If the signal strength does not meet the requirements, the control module will send a signal to the PC to contact the maintenance personnel for maintenance to ensure that the network signal always maintains high speed to facilitate the normal operation of the elevator.
[0024] Example 7 As a preferred embodiment of the present invention: during the constant temperature treatment, the variable temperature structure is used for regulating and controlling the ambient temperature, the ventilation structure is used for processing the ambient air pressure balance, and the drying structure is used for keeping the hardware environment dry at all times; The variable temperature structure can achieve heating and cooling, and lower the temperature to adjust. Ventilation is a building environment control technology that uses ventilation dilution or ventilation exclusion to control the spread and harm of air pollutants and achieve indoor and outdoor air environment quality assurance. The ventilation system is to realize the ventilation function, including a complete set of devices including air inlets, exhaust outlets, air supply ducts, fans, cooling and heating, filters, control systems and other ancillary equipment. Drying is to use heat energy to vaporize the moisture in wet materials, and use air flow or vacuum to take away the vaporized moisture, so as to obtain the operation of drying materials. The variable temperature structure is used to adjust and control the ambient temperature, the ventilation structure is used to handle the balance of ambient air pressure, and the drying structure is used to keep the hardware environment dry at all times, providing good environmental conditions for the normal operation of the elevator car in the shaft.
