[0025] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the embodiments of the utility model will be described in detail below with reference to the drawings. However, those skilled in the art can understand that, in the embodiments of the utility model, many technical details are proposed in order to make the readers better understand the utility model. However, even if there is no such technical details and various changes and modifications based on the following embodiments, the technical scheme claimed by the utility model can be realized. The division of the following embodiments is for the convenience of description, and should not constitute any limitation on the specific implementation mode of the utility model, and the embodiments can be combined and quoted with each other under the premise of no contradiction.

[0026] The installation environment of the elevator control device is complex, and it needs to adapt to the spatial position requirements of different buildings. In some use scenarios, for example, there is usually no special room for installing the elevator control device in the elevator accessory building of rail transit, and the elevator control device needs to be installed in the top area space of the shaft, which will be exposed to the sun, rain, dust invasion and the invasion of various insects and small animals, thereby causing damage to the hardware of the elevator control system, and further affecting the performance of the elevator.

[0027] If dust in the environment invades the inside of the elevator control device, many problems will be caused, such as poor heat dissipation, dust accumulation on the heat sink and fan, hindering heat dissipation, causing system overheating, affecting performance or even damage. Conductive particles in dust can cause circuit short circuit, causing component damage or equipment failure. Dust accumulation at connectors and contacts can cause poor contact, affecting signal transmission and equipment operation. Corrosive substances in dust can accelerate component aging and shorten the life of the frequency converter. Dust entering the fan and other components increases wear and tear, causing increased noise or equipment jamming. Dust reduces the performance of insulating materials, increases the risk of short circuit or breakdown, and threatens equipment safety.

[0028] Rainwater or condensation entering the cabinet and invading the inside of the cabinet can cause many problems, which can cause electrical short circuit, trigger equipment failure or damage. Its impurities and moisture can corrode metal parts and circuits, reducing equipment life. Reduce the performance of insulating materials, increase the risk of short circuit or breakdown, and threaten equipment safety. Sensitive electronic components are easily damaged by water, causing the device to malfunction. Moisture promotes mold growth, further corrodes equipment and affects electrical connections. Causes rust and jamming, affecting operation. Increases the risk of electric shock and electric shock, threatening personnel safety.

[0029] Protective sealing measures can prevent dust and rainwater from entering, but they can affect heat dissipation. Power devices that generate heat, as well as numerous temperature-sensitive electronic components, will experience performance degradation and instability if they operate at elevated temperatures for extended periods. Overheating can damage electronic components, shorten equipment lifespan, and even cause malfunctions, thus reducing the performance of the elevator control system.

[0030] To improve the performance of elevator control devices, embodiments of this utility model relate to an elevator control device. Figure 1 This is a structural schematic diagram of the first type of elevator control device provided in this utility model embodiment, as shown below. Figure 1 As shown, the elevator control device includes: an elevator control module 100, a heat dissipation and air outlet module 200, a first temperature and humidity detection module 300, a protective housing 400, and a wiring module 500.

[0031] Optionally, the elevator control device of this utility model can also be called an elevator control cabinet.

[0032] The elevator control unit has three internal spaces: top floor, middle floor, and bottom floor.

[0033] The first temperature and humidity detection module 300 is located inside the protective housing 400 and inside the top layer of the elevator control device. The first temperature and humidity detection module 300 can detect the temperature and humidity inside the top layer of the elevator control device.

[0034] In this embodiment of the invention, the elevator control device contains many electronic components that are sensitive to temperature and humidity. Excessive temperature or humidity can cause overheating, short circuits, damage, or corrosion of these components, affecting the performance of the elevator control device. The first temperature and humidity detection module 300 can monitor the environment inside the control cabinet in real time, preventing temperature and humidity from exceeding the operating range of the electronic components, protecting their lifespan and stability, and thus improving the performance of the elevator control device. When the elevator control device is operating, the internal electrical components generate heat. Based on the physical principle of hot air rising, the temperature in the upper part of the elevator control device is usually higher than in lower-temperature areas. Therefore, placing the first temperature and humidity detection module 300 on the top floor allows for more accurate monitoring of temperature changes, ensuring that the monitored areas are high-temperature zones that may affect equipment operation. The temperature and humidity on the top floor of the elevator control device are usually more sensitive than on the bottom floor. When abnormal temperature and humidity levels reach a certain point, the sensors on the top floor (the first temperature and humidity detection module 300) can detect the problem earlier.

[0035] The elevator control module 100 is located in the protective shell 400 and in the middle layer of the elevator control device. The elevator control module 100 is used for receiving and processing signals from various components of the elevator (safety components, door lock components, etc.), issuing control instructions, and delivering driving voltage and current to the traction machine. The elevator control module 100 is an integrated module of the driving module, the control module, and the safety function module, and can also be referred to as an intelligent control and driving integrated module.

[0036] The heat dissipation and air outlet module 200 is embedded in the top layer side wall of the protective shell 400, and the air inlet end of the heat dissipation and air outlet module 200 faces the inside of the elevator control device, and the air outlet end of the heat dissipation and air outlet module 200 faces the outside of the elevator control device. The heat dissipation and air outlet module 200 can discharge hot air in the elevator control device to the outside of the elevator control device through the air outlet end.

[0037] The wire passing module 500 is located in the protective shell 400 and in the bottom layer of the elevator control device. The wire passing module 500 contains power cables and signal cables, and the power cables and signal cables enter the device and are electrically connected to other modules through the wire passing module 500.

[0038] In the embodiment of the utility model, one end of the power cable is electrically connected to the traction machine, and the other end is electrically connected to the elevator control module 100; the elevator control module 100 delivers driving voltage and current to the traction machine through the power cable. One end of the signal cable is electrically connected to various components of the elevator, and the other end is electrically connected to the elevator control module 100; the elevator control module 100 receives signals from various components of the elevator through the signal cable.

[0039] Figure 2 It is the first elevator control device module connection schematic diagram provided by the embodiment of the utility model, as shown in Figure 2 The elevator control module 100 is electrically connected to the first temperature and humidity detection module 300, and the elevator control module 100 can obtain the temperature and humidity in the top layer of the elevator control device detected by the first temperature and humidity detection module 300.

[0040] The elevator control module 100 is electrically connected to the heat dissipation and air outlet module 200, and the elevator control module 100 can control the running state of the heat dissipation and air outlet module 200 according to the temperature and humidity in the top layer. The heat dissipation and air outlet module 200 is used for discharging hot air in the elevator control device to the outside of the elevator control device.

[0041] In the embodiment of the utility model, the elevator control module 100 is the brain of the elevator system, responsible for receiving data from various sensors and making decisions based on these data. According to the top layer temperature and humidity data fed back by the temperature and humidity sensor, the elevator control module 100 judges whether to start the heat dissipation and air outlet module 200 to maintain an appropriate temperature, or judges whether to increase or decrease the running gear of the heat dissipation and air outlet module 200.

[0042] When the temperature and humidity data exceeds the set safety threshold, the elevator control module 100 sends a signal to the heat dissipation air outlet module 200 to start the fan of the heat dissipation air outlet module 200 or increase the operating gear of the fan of the heat dissipation air outlet module 200, the fan extracts the hot air inside the elevator control device and discharges it to the outside of the elevator or the ventilation area, thereby cooling the internal environment.

[0043] When the elevator control module 100 detects that the temperature and humidity return to normal, the heat dissipation air outlet module 200 will be turned off to save energy and reduce noise.

[0044] One end of the wire passing module 500 is electrically connected to the elevator control module 100, and the other end of the wire passing module 500 passes through the protective shell 400 and is used for electrically connecting elevator components outside the elevator control device, and the elevator control module 100 controls the operating state of the elevator components through the wire passing module 500.

[0045] The elevator control module 100 can send instructions to start or stop different elevator components according to different situations. For example, the elevator control module 100 sends control signals to the wire passing module 500 according to the needs of the system, and these signals contain specific operation instructions, such as starting the elevator drive, opening and closing the elevator door, controlling the light, etc.

[0046] The wire passing module 500 acts as an intermediary and transmits the signal to the corresponding elevator component after receiving the signal sent by the elevator control module 100. For example, if the instruction is "start the elevator drive", the wire passing module 500 will transmit the signal to the drive system of the elevator to start the movement of the elevator. The task of the wire passing module 500 is to accurately transmit the instructions of the elevator control module 100 to the target component and may make corresponding adjustments according to the feedback information. For example, when the elevator runs to a certain floor, the wire passing module 500 will receive the stop instruction from the elevator control module 100 to ensure that the elevator stops at the specified floor.

[0047] In the embodiment of the utility model, the wire passing module 500 is a relatively independent area; after the cable passes through, it is filled with a flexible gelatinous body that can harden or solidify to prevent dust, small insects and rainwater from invading the system cabinet; the top of the module has two supports, there is flexible foam between the supports, the ends of the supports have connecting holes, the screw is manually tightened through the connecting holes, and rotating the screw can change the distance between the supports, and reducing the distance can compress and fix the cable; the bottom is detachable, which is convenient for repairing and replacing the cable and then refilling the flexible gelatinous body that can harden or solidify.

[0048] The utility model embodiment, elevator control module, temperature and humidity detection module and pass through the module all position protection casing, can avoid the invasion of dust and rain, and the heat dissipation air outlet module is embedded in the top layer side wall of protection casing, and the air inlet end of heat dissipation air outlet module faces in the elevator control device, and the air outlet end of heat dissipation air outlet module faces out of the elevator control device, so that the heat exhaust of the elevator control device exists, and the elevator control device can control the heat exhaust in the elevator control device according to the temperature and humidity in the top layer of elevator control device. Therefore, all electronic components in the elevator control device are protected by the hardware protection of the protection casing, and all electronic components in the elevator control device also do not work in a high-temperature and high-humidity environment for a long time, and the performance of the elevator control device can be improved.

[0049] On the basis of the elevator control device shown in the above Figure 1 The utility model embodiment still provides another elevator control device on the basis of the elevator control device shown in the above, Figure 3 It is the structure schematic diagram of the second elevator control device provided by the utility model embodiment, as shown in Figure 3 The elevator control device further includes: a second temperature and humidity detection module 600.

[0050] The second temperature and humidity detection module 600 is located in the protection casing 400 and in the bottom layer of the elevator control device, and the second temperature and humidity detection module 600 can detect the temperature and humidity in the bottom layer of the elevator control device.

[0051] Figure 4 It is the module connection schematic diagram of the second elevator control device provided by the utility model embodiment, as shown in Figure 4 The elevator control module 100 is electrically connected with the second temperature and humidity detection module 600, the elevator control module 100 can obtain the temperature and humidity in the bottom layer of the elevator control device detected by the second temperature and humidity detection module 600, and the elevator control module 100 controls the operating state of the heat dissipation air outlet module 200 according to the temperature and humidity in the top layer and the temperature and humidity in the bottom layer.

[0052] The influence of temperature and humidity fluctuation in the elevator control device on the elevator system cannot be ignored. Long-term high-temperature or high-humidity environment may accelerate the aging of electrical components. By combining the temperature and humidity data of the top and bottom, the elevator control module 100 can accurately adjust the heat dissipation air outlet module 200 to prevent working in an unsuitable temperature and humidity environment, thereby reducing the risk of excessive heating or cooling and reducing the damage of moisture.

[0053] In the utility model embodiment, the elevator control module combines the temperature and humidity of the top and bottom to regulate and control the operating state of the heat dissipation air outlet module, so that the adjustment and control of the heat dissipation air outlet module are more accurate, and the energy saving property is enhanced.

[0054] On the basis of the elevator control device shown in the above Figure 3 And Figure 4Based on the elevator control device shown in the embodiment of the utility model, the embodiment of the utility model further provides another elevator control device, Figure 5 is the structural schematic diagram of the third elevator control device provided by the embodiment of the utility model, as shown in Figure 5 The elevator control device further comprises an air inlet module 700.

[0055] The air inlet module 700 is embedded in the bottom side wall of the protective shell 400, and the air inlet end of the air inlet module 700 faces the outside of the elevator control device, and the air outlet end of the air inlet module 700 faces the inside of the elevator control device. The air inlet module 700 can suck the normal temperature gas outside the elevator control device into the elevator control device through the air inlet end.

[0056] Figure 6 is the module connection schematic diagram of the third elevator control device provided by the embodiment of the utility model, as shown in Figure 6 The air inlet module 700 is electrically connected with the elevator control module 100, so as to control the running state of the air inlet module 700 according to the temperature and humidity in the top layer and the temperature and humidity in the bottom layer.

[0057] The reason for using air inlet to adjust the temperature and humidity inside the elevator control device is that the main function of the air inlet module 700 is to introduce external air, and the temperature and humidity inside the elevator control device are helped to be adjusted through ventilation. The purpose of doing so is to make cold air enter the inside of the elevator control device to achieve the effect of heat dissipation, so as to prevent the elevator control device from being overheated or having too much moisture, thereby protecting the electronic elements inside the elevator control device.

[0058] The introduction of air by the air inlet module 700 helps to promote the air flow inside the elevator control device, avoiding that the temperature in some areas (such as the top or the bottom) is too high or too low. Good air circulation helps to uniformly distribute cold air, so that each part of the elevator control device can be cooled, thereby maintaining a relatively stable temperature and humidity environment.

[0059] Compared with simply using fans and other equipment to cool, the introduction of external air by the air inlet module 700 for heat dissipation can more efficiently utilize natural air for cooling and reduce energy consumption. When the external temperature is low, the air inlet module 700 can more energy-efficiently reduce the temperature inside the elevator control device, avoiding excessive dependence on electrically driven fans or other cooling devices.

[0060] The air inlet module 700 can automatically adjust according to the temperature and humidity of the top and bottom of the elevator control device. For example, when the temperature of the top is too high, the air inlet module 700 can introduce relatively cool air, and when the humidity of the bottom is high, dry air can be introduced to better adapt to environmental changes.

[0061] In the embodiment of the utility model, the air inlet module helps to control the temperature and humidity in the elevator control device by introducing external air, so as to achieve the purpose of heat dissipation and moisture management, thereby protecting the device and improving stability.

[0062] On the basis of the elevator control device shown in the above Figure 1 The embodiment of the utility model also provides an elevator control device, Figure 7 It is the structural schematic diagram of the fourth elevator control device provided by the embodiment of the utility model, as shown in Figure 7 The elevator control device further comprises a water absorption module 800.

[0063] The water absorption module 800 is located in the top layer of the elevator control device and is close to the upper inner wall of the top layer.

[0064] In the embodiment of the utility model, the water absorption module 800 can be a water absorption plate. The water absorption plate can withstand high temperature, has a fine microporous structure, can store water, and can reduce the humidity in the elevator control device. When the fan of the heat dissipation air outlet module 200 rotates, the air flow is driven, the evaporation of water vapor is accelerated, the humidity in the elevator control device is reduced, and condensation is prevented.

[0065] As shown in Figure 7 In a specific implementation of the heat dissipation air outlet module 200, the heat dissipation air outlet module 200 comprises: a first heat dissipation fan 201 and a second heat dissipation fan 202.

[0066] The first heat dissipation fan 201 and the second heat dissipation fan 202 are respectively embedded in the opposite side walls of the top layer of the protective shell 400, and the air inlet ends of the first heat dissipation fan and the second heat dissipation fan are all faced to the inside of the elevator control device, and the air outlet ends of the first heat dissipation fan and the second heat dissipation fan are all faced to the outside of the elevator control device.

[0067] The heat generated by the heating device is transported to the outside of the elevator control device in the form of forced air outlet by the first heat dissipation fan 201 and the second heat dissipation fan 202 placed on the top of the protective shell 400, so as to avoid overheating of the maintaining device. When the fan rotates, the air flow is driven, the evaporation of water vapor is promoted, the water vapor is extracted from the shell, the internal humidity is reduced, and the heat is taken away at the same time.

[0068] The elevator control module 100 is electrically connected with the first heat dissipation fan 201 and the second heat dissipation fan 202, so as to control the running state of the first heat dissipation fan and the second heat dissipation fan according to the temperature and humidity in the top layer.

[0069] As shown in Figure 7 In a specific implementation of the air inlet module 700, the air inlet module 700 comprises: a first air inlet fan 701 and a second air inlet fan 702.

[0071] The first air inlet fan 701 and the second air inlet fan 702 can respectively suck external air into the elevator control device.

[0072] The elevator control module 100 is electrically connected with the first air inlet fan 701 and the second air inlet fan 702, so as to control the running state of the first air inlet fan 701 and the second air inlet fan 702 according to the temperature and humidity in the top layer and the temperature and humidity in the bottom layer.

[0073] As shown in Figure 7 , the elevator control device further comprises at least one layer of first filter screen 801 and at least one layer of first filter cotton 802, the first filter screen 801 is arranged at the air outlet end of the heat dissipation air outlet module 200, and the first filter cotton 802 is tightly attached to the side of the first filter screen 801 which is faced outward of the elevator control device.

[0074] The heat dissipation air outlet module 200 is arranged at the top position in the elevator control device, and uses the fan to suck the internal hot air outward, which is consistent with the normal air flow direction, so as to improve the ventilation efficiency; in order to avoid the invasion of external objects such as rainwater, dust and insects, the air outlet of the heat dissipation air outlet module 200 is provided with the first filter screen 801 and the first filter cotton 802; the first filter screen 801 has an array of stepped structures, the stepped surface has a slope, and the rainwater flows down along the slope surface and cannot be accumulated on the surface of the first filter screen 801, and each layer of the stepped bottom has a breathable hole, which facilitates air exchange. There is first filter cotton between the first filter screen 801 and the fan, and the hole structure of the first filter cotton 802 can make the air pass through while isolating dust particles and insects and other foreign matters.

[0087] Optionally, as shown in Figure 7 , the elevator control device further includes a power module 902 for supplying power to the electrical module.

The wire passing module 500 is filled with the flexible gel body 502 which can be hardened or solidified, so as to prevent dust, small insects and rainwater from invading the elevator control device.

[0089] In the elevator control device, a group of fans can be arranged at the top of the elevator control device, in the elevator control module 100 and at the bottom of the elevator control device, and a total of three groups of fans; the temperature and humidity detection module can be arranged at the top of the elevator control device, in and outside the elevator control module 100 and at the bottom of the elevator control device, and a total of four groups of temperature and humidity detection modules. The threshold value of temperature and humidity can be set according to different strategies, and the working state of the three groups of fans is controlled. When the three groups of fans work at the same time, the heat dissipation efficiency is the highest. The temperature and humidity state in the elevator control module 100 reflects the heating condition of the core device, and is one of the reference values for evaluating the heat dissipation effect of the system. The difference between the temperature and humidity of the heat dissipation air outlet and the temperature and humidity of the air inlet is the second reference value for evaluating the heat dissipation effect of the system.

The heat dissipation air blowing module 200 and the air inlet module 700 for heat dissipation are mostly located in the top layer and the bottom layer, and the height of the top layer and the bottom layer is relatively low, so the space occupied by the module for heat dissipation is relatively small.
