Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in FIG. 1, there is provided a cooling tower comprising: a housing 110 and a control module 120 (illustratively, the control module 120 may employ STM32 series embedded control chips); an access door 111 and a fan 130 are provided on the housing 110. Since the hot air (including water vapor) rises during the heat dissipation process, the fan 130 is generally disposed at the top of the housing, so that the hot air can be better drawn out of the cooling tower through the fan 130. In particular embodiments, the fan 130 is disposed at other locations of the housing, without limitation.
A pressure sensor 140 is installed at a door bolt of the access door 111, and the pressure sensor 140 is used to detect a first negative pressure in the cooling tower.
Specifically, during normal operation of the cooling tower, the fan 130 normally operates to draw hot air from the cooling tower, and there is a difference in air pressure between the air outside the cooling tower and the air pressure inside the cooling tower. In this way, a pressure difference is formed between the inside and the outside of the cooling tower maintenance door 111, the maintenance door 111 receives the thrust from the external pressure to the cooling tower, and the pressure sensor 140 is disposed at the door bolt of the maintenance door 111 (specifically, the pressure sensor 140 is disposed at the side of the door bolt of the maintenance door 111 facing the cooling tower), so that the pressure received by the maintenance door can be detected, and for convenience of description, the detected pressure is defined as the first negative pressure. By way of example, the pressure sensor 140 may include a pressure sensitive sensor body for detecting a first negative pressure and a transmitter for generating the detected first negative pressure to the control module 120.
The control module 120 may be disposed on the housing 110 of the cooling tower, may be disposed within the housing 110, or may be located elsewhere, without limitation.
The control module 120 is connected to the pressure sensor 140, and the control module 120 is configured to determine whether the fan has a fault according to the first negative pressure and the historical data.
Specifically, the control module 120 is connected to the pressure sensor 140, and after the pressure sensor 140 detects the first negative pressure, the first negative pressure is sent to the control module 120 (for example, the pressure sensor 140 may send the first negative pressure to the control module 120 through a communication protocol such as a serial port protocol), and the control module 120 determines whether a fan in the cooling tower has a fault according to the first negative pressure and historical data, where the historical data refers to the first negative pressure before the current time and the first negative pressure at the current time are obtained. Or the control module 120 determines whether the fan in the cooling tower has a fault according to the change condition of the first negative pressure, and determines that the fan in the cooling tower has a fault when the first negative pressure changes. In this case, the electrode for driving the fan 130 belongs to a fixed-frequency electrode, that is, the output power of the driving motor is constant, or the fan 130 is a fixed-frequency fan (rotation speed is fixed).
As another embodiment, if the motor driving the fan 130 is a variable frequency electrode (or the fan 130 is a variable frequency fan), in practical application, different powers may be used to drive the fan 130 according to the practical situation, in this case, the control module 120 is further configured to obtain the output power of the driving motor, determine the rotation speed of the fan 130 according to the output power, determine the experimental negative pressure in the cooling tower according to the rotation speed of the fan 130, compare the first negative pressure and the experimental negative pressure that are actually obtained, and if the first negative pressure and the experimental negative pressure are not equal (or the error between the first negative pressure and the experimental negative pressure exceeds the preset range), indicate that the fan is faulty.
It should be noted that the cooling tower further includes other auxiliary circuits, such as a power supply, to ensure that each module works normally, which is not described herein. By way of example, the communication module may employ an NRF24L01 wireless communication module, ensuring reliable wireless communication within a range of about another 10 m.
The cooling tower includes: a housing and control module and a communication module; a fan and an access door are arranged on the shell, a pressure sensor is arranged at a door bolt of the access door, and the pressure sensor is used for detecting first negative pressure in the cooling tower; the control module is connected with the pressure sensor and is used for determining whether the fan has faults according to the first negative pressure and the historical data. Through the mode, the pressure sensor is installed at the door bolt of the access door of the cooling tower, when the fan is used for working normally, the pressure difference is generated inside and outside the cooling tower, the access door can receive the thrust phenomenon in the cooling tower from the external pressure, the access door of the cooling tower is detected to receive the external thrust, the first negative pressure is obtained, then whether the fan in each cooling tower is detected to be faulty or not according to the first negative pressure, and therefore the detection accuracy is improved.
In one embodiment, as shown in FIG. 2, the cooling tower further comprises: the communication module 150, the communication module 150 is connected with the control module 120, and the communication module 150 is used for communicating with other cooling towers, obtaining the second negative pressure in other cooling towers, and transmitting the second negative pressure to the control module 120.
Specifically, in some cooling systems, a plurality of cooling towers are provided, and each cooling tower may include: a housing 110, a control module 120, a fan 130, a pressure sensor 140, and a communication module 150; an access door 111 and a fan 130 are provided on the housing 110, and a pressure sensor 140 is installed at a door bolt of the access door 111, that is, each cooling tower has the same structure.
Wherein the control module 120 in each cooling tower is connected to the communication module 150 and the pressure sensor 140, respectively. The pressure sensor 140 of each cooling tower is used for detecting the first negative pressure in the cooling tower, and the communication module 150 on each cooling tower can be in communication connection with the communication modules 150 on other cooling towers. The specific location of the communication module 150 is not limited.
The control module 120 is further configured to determine whether the fan 130 has a fault according to the second negative pressure and the first negative pressure.
Specifically, the control module 120 in any one cooling tower may obtain the negative pressure in the other cooling towers through the communication module 150, and for convenience of explanation, the negative pressure in the other cooling towers is defined as the second negative pressure. The control module 130 compares the obtained first negative pressure with the second negative pressure to determine whether there is a failure in the fan 130 belonging to the same cooling tower as the process 120.
Further, the number of cooling towers is 3 or more in order to more accurately determine the position of the failed fan.
If the number of cooling towers is 2, comparing the obtained first negative pressure with the second negative pressure, only determining that the fan has failed can be performed, and determining which cooling tower has failed can not be performed. Meanwhile, the probability of simultaneous occurrence of faults of the fans on the cooling towers is low, and the heat dissipation power of the cooling towers in the same system is generally required to be consistent, so that the number of the cooling towers is more than 3, if one fan breaks down, the negative pressure of the cooling tower where the fan is located is different from the negative pressure in other cooling towers, and therefore, the fan with the fault can be easily and accurately positioned. At this time, the control module 120 is further configured to compare the first negative pressure with the plurality of second negative pressures, and determine that the fan has a fault if the first negative pressure is different from the plurality of second negative pressures.
For example, assuming that 3 cooling towers are disposed in one cooling system, the first cooling tower, the second cooling tower and the third cooling tower are respectively, a control module in the first cooling tower obtains negative pressure (namely, first negative pressure) in the first cooling tower through a pressure sensor, and obtains negative pressure (namely, second negative pressure) in the second cooling tower and the third cooling tower through a communication module, the first negative pressure and the two second negative pressures are compared, and if the first negative pressure is different from the two negative pressures, the fan in the first cooling tower is indicated to be faulty.
In a specific implementation, when a plurality of cooling towers exist at the same time, a shell, a control module, a fan, a pressure sensor and a communication module can be arranged in any one of the plurality of cooling towers, the shell, the fan, the pressure sensor and the communication module are arranged in other cooling towers, the control module is arranged on only one cooling tower, negative pressure in other cooling towers is obtained through the communication module to judge, and if the negative pressure in one cooling tower is different from the negative pressure in other cooling towers, the fan of the cooling tower is indicated to be failed. Only one control module is needed, so that the use of processing is greatly reduced, and the cost is saved.
In one embodiment, as shown in FIG. 3, a cooling tube 160 is inserted through the cooling tower, and one end of the cooling tube 160 is suspended below the fan 130. The fan 130 is facilitated to remove the water vapor in the cooling pipe 160 from the cooling tower.
Based on the same inventive concept, the embodiment of the application also provides a fault detection method for a cooling tower for realizing the cooling tower. The implementation of the solution to the problem provided by this method is similar to that described in the above method, so the specific limitations in the embodiments of the fault detection method for one or more cooling towers provided below may be referred to the limitations of the cooling tower method hereinabove, and will not be described herein.
In one embodiment, as shown in fig. 4, there is provided a fault detection method of a cooling tower, which may be used for the cooling tower shown in any of the above embodiments, the method including:
step 410, obtaining a first negative pressure in the cooling tower;
step 420, determining whether the fan has a fault according to the first negative pressure and the historical data.
Specifically, in the normal operation process of the cooling tower, the fan normally works to pump out hot air in the cooling tower from the cooling tower, and the air outside the cooling tower and the air pressure inside the cooling tower are different. So, can form pressure difference inside and outside the cooling tower maintenance door, the maintenance door can receive external pressure to the thrust in the cooling tower, and pressure sensor sets up in maintenance door keeper department (specifically, pressure sensor sets up in the maintenance door keeper one side in facing the cooling tower), can detect the pressure that the maintenance door received, for the convenience of description, defines the pressure of measuring as first negative pressure. After the control module in the cooling tower obtains the first negative pressure detected by the pressure sensor, determining whether a fan in the cooling tower has a fault or not according to the first negative pressure and historical data, wherein the historical data refers to the first negative pressure at the current moment and the first negative pressure before the current moment. Or the control module determines whether the fan in the cooling tower has a fault according to the change condition of the first negative pressure, and determines that the fan in the cooling tower has a fault when the first negative pressure changes. In this case, the electrode for driving the fan belongs to a fixed-frequency electrode, that is, the output power of the driving motor is constant, or the fan is a fixed-frequency fan (the rotation speed is fixed).
As another embodiment, if the motor for driving the fan is a variable frequency electrode (or the fan is a variable frequency fan), in practical application, different powers can be adopted for driving the motor according to practical situations to drive the fan, in this case, the control module is further configured to obtain the output power of the driving motor, determine the rotation speed of the fan according to the output power, determine the experimental negative pressure in the cooling tower according to the rotation speed of the fan, compare the first negative pressure and the experimental negative pressure that are actually obtained, and if the first negative pressure and the experimental negative pressure are not equal (or the error of the first negative pressure and the experimental negative pressure exceeds the preset range), indicate that the fan has a fault.
Through the mode, the pressure sensor is installed at the door bolt of the access door of the cooling tower, when the fan is used for working normally, the pressure difference is generated inside and outside the cooling tower, the access door can receive the thrust phenomenon in the cooling tower from the external pressure, the access door of the cooling tower is detected to receive the external thrust, the first negative pressure is obtained, then whether the fan in each cooling tower is detected to be faulty or not according to the first negative pressure, and therefore the detection accuracy is improved.
In one embodiment, the method further comprises:
step 430, obtaining a second negative pressure in other cooling towers;
in some cooling systems, a plurality of cooling towers are provided, and each cooling tower may include: the device comprises a shell, a control module, a fan, a pressure sensor and a communication module; an access door and a fan are arranged on the shell, and a pressure sensor is arranged at a door bolt of the access door, namely, the structure of each cooling tower is the same.
The control module in each cooling tower is respectively connected with the communication module and the pressure sensor. The pressure sensor of each cooling tower is used for detecting the first negative pressure in the cooling tower, and the communication module on each cooling tower can be in communication connection with the communication modules on other cooling towers. The specific location of the communication module is not limited.
Correspondingly, in step 420, the determining whether the fan has a fault according to the first negative pressure and the historical data includes:
step 421, determining whether the fan has a fault according to the second negative pressure and the first negative pressure.
Specifically, the control module in any one cooling tower can obtain the negative pressure in other cooling towers through the communication module, and for convenience of explanation, the negative pressure in other cooling towers is defined as the second negative pressure. The control module compares the obtained first negative pressure with the second negative pressure, so as to determine whether a fan belonging to the same cooling tower as the control module has a fault or not.
Further, the number of cooling towers is 3 or more in order to more accurately determine the position of the failed fan.
If the number of cooling towers is 2, comparing the obtained first negative pressure with the second negative pressure, only determining that the fan has failed can be performed, and determining which cooling tower has failed can not be performed. Meanwhile, the probability of simultaneous occurrence of faults of the fans on the cooling towers is low, and the heat dissipation power of the cooling towers in the same system is generally required to be consistent, so that the number of the cooling towers is more than 3, if one fan breaks down, the negative pressure of the cooling tower where the fan is located is different from the negative pressure in other cooling towers, and therefore, the fan with the fault can be easily and accurately positioned.
At this time, determining whether the fan has a fault according to the second negative pressure and the first negative pressure includes:
comparing the first negative pressure with a plurality of second negative pressures, and if the first negative pressure is different from the plurality of second negative pressures, determining that the fan has a fault.
For example, assuming that 3 cooling towers are disposed in one cooling system, the first cooling tower, the second cooling tower and the third cooling tower are respectively, a control module in the first cooling tower obtains negative pressure (namely, first negative pressure) in the first cooling tower through a pressure sensor, and obtains negative pressure (namely, second negative pressure) in the second cooling tower and the third cooling tower through a communication module, the first negative pressure and the two second negative pressures are compared, and if the first negative pressure is different from the two negative pressures, the fan in the first cooling tower is indicated to be faulty.
In a specific implementation, when a plurality of cooling towers exist at the same time, a shell, a control module, a fan, a pressure sensor and a communication module can be arranged in any one of the plurality of cooling towers, the shell, the fan, the pressure sensor and the communication module are arranged in other cooling towers, the control module is arranged on only one cooling tower, negative pressure in other cooling towers is obtained through the communication module to judge, and if the negative pressure in one cooling tower is different from the negative pressure in other cooling towers, the fan of the cooling tower is indicated to be failed.
