The first sub-cabinet 10 and the second sub-cabinet 20 may be provided with a plurality of devices, and the devices in the first sub-cabinet 10 and the second sub-cabinet 20 generate heat in daily operation, and the heat is driven by a fan or naturally diffused into an internal environment. To ensure the working environment of the apparatus, it is necessary to discharge cold air by using the air conditioner 40, and to ensure the normal operation of the apparatus by using heat exchange between the cold air and the hot air. On the one hand, in order to ensure that the air conditioner 40 can provide the cold air required by the equipment, and on the other hand, in order to avoid the occurrence of the failure of the air conditioner 40, the first sub-cabinet 10 and the second sub-cabinet 20 both comprise at least two air conditioners 40, so that at least one air conditioner 40 can normally work to provide the cold air when the equipment works.

The temperature of the cooling fluid of the air conditioner 40 increases after the heat is absorbed, and the cooling fluid with high temperature needs to be cooled down for subsequent refrigeration. In the present embodiment, referring to fig. 1 and 2, the refrigerating apparatus 30 is an apparatus for reducing the temperature of the cooling liquid of the plurality of air conditioners 40 and distributing the cooling liquid to the plurality of air conditioners 40.

The housing 70 may be made of metal, so as to avoid static electricity accumulation caused by the operation of the internal equipment, which may damage the components of the equipment. And because the inside of the housing 70 involves circulation of liquid, the housing 70 may be made of stainless steel. The housing 70 includes a floor 71, the floor 71 being adapted to carry equipment inside the refrigeration unit 30. The coolant temperature inside the pipe is lower than the internal environment, and the water vapor in the inside will cool and liquefy on the outer wall of the pipe, causing a pipe water leakage warning.

In this embodiment, referring to fig. 5, a control method of a data cabinet is also provided, which can be applied to the data cabinet 1 described above.

Step S110: and acquiring information acquired by the water leakage detection device, and sending out alarm information when the water leakage detection device detects that the loop leaks, wherein the alarm information comprises the position of the loop where the water leakage occurs.

First, the information collected by the water leakage detection device includes a voltage value and a current value between the first detection electrode and the second detection electrode. And the refrigerating device is preset with corresponding voltage values, current values and unit length resistance values of the first detection electrode and the second detection electrode.

When the loop leaks water, the first detection electrode and the second detection electrode are short-circuited at the medium attachment position, and a current loop is formed. The current value and the voltage value in the current loop will change greatly, and the information will be obtained by the water leakage detection device. The water leakage detection device calculates a resistance value by using the current and voltage law of the same loop in the ohm law of the closed circuit. And comparing the resistance value with the unit length resistance values of the first detection electrode and the second detection electrode to obtain the distance between the medium attachment position and the electrode tail end of the water leakage detection device. A wired electrical connection or a wireless connection is established between the water leakage detection device and the control device, wherein the wireless connection comprises, but is not limited to, a bluetooth connection, a Zigbee connection, and the like. Therefore, the water leakage detection device can transmit alarm information to the control device through the connection. Specifically, the alarm information includes information such as a water leakage loop, a water leakage position, a water leakage time, a water leakage range, and the like, and the water leakage detection device converts a plurality of information sets into electric signals, bluetooth signals, and the like, and continuously transmits the electric signals, the Bluetooth signals, and the like to the control device. When the water leakage detection device cannot detect water leakage, the water leakage detection device can disconnect the alarm information transmission.

For example, a current loop in which the current value and the voltage value are 1A and 2V, respectively, and the resistance values of the first detection electrode and the second detection electrode are 1 Ω per meter is formed by water leakage in the loop. By utilizing the ohm law of a closed circuit, the total resistance value of the current loop is 2 omega without considering the influence of other components in the water leakage detection device on the resistance value. And comparing the total resistance value with the unit length resistance value to obtain that the total length of the current loop is 2m, the distance from the medium attachment position to the electrode end of the water leakage detection device is half of the total length, and finally obtaining that the distance from the medium attachment position to the electrode end of the water leakage detection device is 1m, and sending the distance information to a control device or other equipment.

In a data cabinet, a pipeline with a complex pipeline design has a water leakage risk, and a plurality of troubles exist in terms of water leakage alarming and maintenance. The water leakage detection device is arranged on the loop, and can be used for detecting water leakage of the pipeline in real time. And the position of water leakage is transmitted to the control device for later maintenance of staff. The equipment safety in the data cabinet is protected, and the maintenance workload of workers is reduced.

Referring to fig. 6, it should be understood that the control method of the present embodiment has the same or corresponding implementation steps as those of the foregoing embodiment, and specific descriptions of these same or corresponding implementation steps may be referred to what is provided in the foregoing embodiment, which will not be repeated.

Step S210: and acquiring information acquired by the water leakage detection device, and sending out alarm information when the water leakage detection device detects that the loop leaks, wherein the alarm information comprises the position of the loop where the water leakage occurs.

Step S220: and when the triggering time of the alarm information is equal to the preset time, acquiring the ponding information of each area on the bottom plate of the shell.

Firstly, in order to avoid the situation that liquid splashes or ambient air is wet, etc., the water leakage detection device carries out false alarm. The refrigerating device is provided with a preset time length, and the preset time length can be calculated from the alarm of the water leakage detection device. In order to ensure the safety of equipment and reduce the loss of cooling liquid, the preset time length is not set too long. For example, the preset time period may be set to 5 minutes.

In one embodiment, the plurality of second sensors are distributed in respective areas on the base plate, and the second sensor of each area is capable of detecting water accumulation information of the corresponding area. When the triggering time of the alarm information is equal to the preset time, the control device can acquire the ponding information of the corresponding area from the plurality of second sensors. The ponding information comprises relevant information such as ponding position, ponding amount and the like.

In another embodiment, each area of the bottom plate is provided with a water leakage detection device, and the water leakage detection device can acquire the water leakage position and determine the information of the area where the water leakage position is located. For example, the bottom plate includes a first area and a second area, the total length of the water leakage detecting device is 2m, the water leakage detecting device is arranged in the first area within a range of 0-1m, the water leakage detecting device is arranged in the second area within a range of 1-2 m, and the position parameter on the water leakage detecting device can be calculated from any one of two ends of the water leakage detecting device. When water leakage at the position of 0.5m of the water leakage detection device is detected, the water leakage of the first area can be judged when the water leakage of the position of 0.5m is within the length interval of 0-1 m.

Step S230: and when the accumulated water in the area corresponding to the loop in which water leakage occurs exceeds a water accumulation threshold value, detecting the flow of the loop.

Firstly, a water accumulation threshold is preset in the control device, and the water accumulation threshold comprises relevant information such as water accumulation amount, water accumulation position and the like. Wherein, regarding the detection of the water accumulation amount, the control device can be obtained according to the water accumulation area or the water accumulation height of the bottom plate detected by the second sensor. The accumulated water corresponding to the area exceeds the preset accumulated water amount, and the flow of the loop is detected by using a first sensor; the accumulated water corresponding to the area does not exceed the preset accumulated water amount, and the detection of the loop flow is not performed.

Regarding the detection of the water accumulation position, the corresponding relation between each pipeline and each region is preset in the control device. Specifically, a plurality of second sensors are respectively arranged in each area of the bottom plate, the corresponding relation between each water leakage detection device of the preset pipeline and each second sensor in the control device is further determined. The ponding threshold value can be the region position corresponding to the water leakage pipeline in the alarm information, and the ponding information transmitted by the second sensor is compared with the region information corresponding to the water leakage pipeline calculated by the alarm information. The position relationship of the two is consistent, the leakage of the pipeline can be confirmed, and the flow of the loop is detected by using a first sensor; the positional relationship between the two is inconsistent, and leakage of the pipe cannot be confirmed, and detection of the circuit flow rate is not performed. By utilizing the corresponding relation between the area and the pipeline, whether liquid leakage occurs or not can be accurately judged, and the occurrence of false alarm is reduced.

Step S240: if the flow rate of the flow rate loop is less than 1/2 of the set flow rate and the number of closed loops is less than 2, closing the leaked loops; if the flow rate of the flow rate loop is less than 1/2 of the set flow rate and the number of closed loops is more than 2, continuously sending out alarm information.

Firstly, a preset flow parameter is set on a control device, and the preset flow comprises related information such as temperature difference at two ends of a flow loop, on-off state of the loop and the like. The temperature difference at two ends of the flow loop can be the medium temperature difference in the first branch pipe and the second branch pipe. The current flow information of the flow loop is transmitted to the control device through the first sensor, and the flow information comprises the temperature difference of the flow loop, the flow velocity, the on-off state of the loop and the like.

And then, comparing the flow information with the preset flow, and controlling the water leakage loop according to the comparison result. In one embodiment, the flow information may be the cooling capacity on the corresponding circuit. The comparison of the preset loop refrigerating capacity and the current loop refrigerating capacity can be further realized by utilizing the comparison of the preset loop temperature difference and the current loop temperature difference, and when the loop temperature difference is smaller than 1/2 of the set temperature difference and the number of closed loops is smaller than 2, the corresponding water leakage loop is closed through the electromagnetic valve of the flow loop; when the loop temperature difference is less than 1/2 of the set temperature difference and the number of closed loops is more than 2, only continuously sending out alarm information, and not closing the corresponding water leakage loop; when the loop temperature difference is greater than 1/2 of the set temperature difference, no matter whether the number of closed loops is more than 2, the alarm information is continuously sent, and the corresponding water leakage loop is not closed. Preferably, when the water leakage loop is closed, the control device simultaneously controls the corresponding air conditioner to be closed. The idle running condition of the air conditioner is reduced, resources are saved, and the service life of the air conditioner is prolonged.

In another embodiment, the flow information may be a flow rate of water on a corresponding loop, comparing a preset loop flow rate with a current loop flow rate, and closing a corresponding water leakage loop through an electromagnetic valve of the flow loop when the loop flow rate is less than 1/2 of the set flow rate and the number of closed loops is less than 2; when the water flow rate of the loop is less than 1/2 of the set water flow rate and the number of the closed loops is more than 2, only continuously sending out alarm information, and not closing the corresponding water leakage loop; when the water flow rate of the loop is greater than 1/2 of the set water flow rate, no matter whether the number of closed loops is more than 2, the alarm information is continuously sent, and the corresponding water leakage loop is not closed.

The alarm authenticity is ensured by setting the alarm time length, and false alarm caused by loop wetness and other conditions is avoided. And the time for alarming to overhaul is needed, the data cabinet is normally operated or stopped for overhaul, and the staff cannot enter the inspection working condition in time. However, water leakage is still occurring, possibly causing losses. The control device can timely acquire water leakage information and flow information and control the electromagnetic valve to close the corresponding loop. The risk of loss caused by water leakage is reduced, and the normal use of the data cabinet is protected.

The above embodiments are only for illustrating the technical solution of the present application, and are not limiting thereof; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the embodiments of the present application, and are intended to be included within the scope of the present application.
