In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Example one
The embodiment of the invention solves the following technical problems:
1. the temperature sensing bulb is in fault or inaccurate in detection, and the comfort and the heat exchange effect of the air conditioner are directly influenced; if the air conditioner indoor unit environment temperature sensing bulb, inner tube temperature sensing bulb, outer machine environment temperature sensing bulb, outer tube temperature sensing bulb, outer machine temperature sensing bulb and outer machine blast pipe temperature sensing bulb etc. of breathing in appear damaging, will fix a resistance and do not change along with the temperature, probably appear the indoor unit and do not indicate the fault code. According to the existing method, it is difficult to judge which thermal bulb has a fault after sale, if a detection device is used, the internal machine or the external machine sends detected data to the detection device, and the detection device can give a fault or abnormal prompt, so that the hidden problem is conveniently checked.
2. The fan of the air conditioner directly influences the heat exchange effect of the air conditioner, if the fan or a hardware control circuit of a controller is damaged, a fault code can be prompted under normal conditions, if hidden faults of an inner fan and an outer fan need to be checked, the normal air conditioner can be set according to a remote controller and executed according to a set state, how to judge the hidden faults of the inner fan and the outer fan can be judged, detection equipment can be used, after communication is established, different set rotating speeds are sent to an inner unit or an outer unit, after the inner unit or the outer unit is executed according to the setting, the rotating speeds of the different fans are sampled by the controller, the pulse values of the motor feedback signals are different, the detection equipment detects the pulse values of the fan at different rotating speeds, the rotating speed of the fan is calculated, and whether the fan is normal or not is judged; and detecting several groups of data to judge whether the fan is normal.
3. The fan operation is accompanied by noise generation, or the air volume of the feedback air conditioner is insufficient, and detection equipment is needed to achieve fine adjustment of the rotating speed of the fan; the air conditioner has poor refrigerating and heating effects, and the detection setting also needs to be borrowed to achieve the purposes of adjusting the working frequency of the compressor and the like.

The invention can simplify the maintenance of the air conditioner under the condition that the air conditioner does not prompt the fault code, so that after-sales personnel can more quickly handle the fault problem and conveniently locate the fault position. After-sales personnel can also upload fault data to the system, so that remote troubleshooting is facilitated; with the increase of the service life of the air conditioner, the refrigerating or heating effect of the air conditioner is poor, the noise of the air conditioner is likely to increase, and on the basis of not increasing the cost, the detection equipment can be used after sale to adjust the working state of the air conditioner, so that the purpose of rapidly processing the after-sale problems is achieved.
Fig. 1 is a schematic diagram of connection between an air conditioner detection device and an air conditioner internal and external units according to an embodiment of the present invention, in which an internal unit controller or an external unit controller separately establishes communication with the detection device, and if the internal unit controller cannot establish communication with the detection device, an internal unit motherboard communication circuit is abnormal; similarly, if the external machine controller cannot establish communication with the detection equipment, the external machine mainboard communication circuit is abnormal; if the detection equipment can be communicated with the inner machine or the outer machine normally, the communication circuit of the inner machine mainboard and the communication circuit of the outer machine mainboard are normal, and subsequent detection work can be carried out.
According to an embodiment of the present invention, there is provided a control method of an air conditioner detection apparatus, as shown in fig. 2, the method according to the embodiment includes:
step S101, detecting whether a target component in the air conditioner to be detected has a fault;
in this embodiment, the air conditioner detection device may detect operation conditions of various target components in the air conditioner to be detected, so as to determine whether a certain target component has a fault. For example, the air conditioner detecting apparatus may detect a motor, various temperature sensing bags, a strong electric component, a weak electric component, and the like in the air conditioner to determine whether or not they are malfunctioning.
In this embodiment, the air conditioner detection device includes: a temperature sensing bulb is externally connected; when the air conditioner detection equipment detects the fault of the target temperature sensing bulb in the air conditioner, the following two modes can be adopted:
the first mode is that the detection temperature of the target thermal bulb is obtained as a first detection temperature; acquiring the detection temperature of the external temperature sensing bulb as a second detection temperature; the external temperature sensing bulb is positioned at a preset position so as to detect the temperature of the same preset space with the target temperature sensing bulb; judging whether the absolute value of the difference value of the first detection temperature and the second detection temperature is smaller than a first preset threshold value or not; and when the absolute value of the difference value between the first detection temperature and the second detection temperature is not less than the first preset threshold value, determining that the target temperature sensing bulb has a fault.
In order to make the fault detection result more accurate, the first method for detecting whether the target component in the air conditioner to be detected is faulty further includes: when the absolute value of the difference value between the first detection temperature and the second detection temperature is not smaller than the first preset threshold, obtaining an AD value corresponding to the target thermal bulb; obtaining a temperature value corresponding to the AD value as a third detected temperature based on the AD value; judging whether the absolute value of the difference value of the first detection temperature and the third detection temperature is smaller than a first preset threshold value or not; and when the absolute value of the difference value between the first detection temperature and the third detection temperature is not less than the first preset threshold value, determining that the target temperature sensing bulb has a fault.
Wherein the AD value is an AD voltage value; the obtaining, based on the AD value, a temperature value corresponding to the AD value as a third detected temperature includes: and searching a temperature value corresponding to the AD voltage value in a preset table as a third detection temperature based on the AD voltage value.
Specifically, the target bulb includes: the temperature control device comprises an inner machine environment temperature sensing bulb, an inner pipe temperature sensing bulb, an outer machine environment temperature sensing bulb, an outer pipe temperature sensing bulb, an outer machine air suction temperature sensing bulb and an outer machine exhaust temperature sensing bulb. When the temperature sensing bags are subjected to fault detection, the communication terminal of the air conditioner detection equipment is connected with an internal unit or an external unit communication line of an air conditioner through a communication line, and the detection equipment is operated after the power is on to obtain the detection temperature of one target temperature sensing bag.
Taking the fault detection of the internal machine environment temperature sensing bulb as an example, after the air conditioner detection equipment is connected with the internal machine of the air conditioner, the external temperature sensing bulb is connected to the terminal of the detection equipment, and the external temperature sensing bulb is arranged in the room where the internal machine is located, so as to detect the indoor environment temperature where the internal machine is located. As shown in fig. 3, after the detection device is powered on, the detection device first obtains a detection temperature of the internal machine environment thermal bulb as a first detection temperature, and obtains a detection temperature of the external thermal bulb as a second detection temperature; then, the detection equipment judges whether the absolute value of the difference value between the first detection temperature and the second detection temperature is smaller than a first preset threshold value, and when the absolute value of the difference value between the first detection temperature and the second detection temperature is smaller than the first preset threshold value, the error between the detection temperature of the internal machine environment temperature sensing bulb and the detection temperature of the external temperature sensing bulb is small, the detection temperature of the internal machine environment temperature sensing bulb is correct, namely the internal machine environment temperature sensing bulb works normally; when the absolute value of the difference value between the first detection temperature and the second detection temperature is not smaller than a first preset threshold value, the error between the detection temperature of the internal machine environment temperature sensing bulb and the detection temperature of the external temperature sensing bulb is larger, and the detection temperature of the internal machine environment temperature sensing bulb is incorrect, namely, the internal machine environment temperature sensing bulb is determined to be in fault.
In the above process, in order to perform fault detection more accurately, when the absolute value of the difference between the first detected temperature and the second detected temperature is not less than the first preset threshold, further obtaining an AD voltage value corresponding to the internal-engine-environment thermal bulb, based on the AD voltage value, the detection device searches a temperature value corresponding to the AD voltage value in a preset table as a third detected temperature, and then determines whether the absolute value of the difference between the first detected temperature and the third detected temperature is less than the first preset threshold, and when the absolute value of the difference between the first detected temperature and the third detected temperature is not less than the first preset threshold, that is, when the error between the first detected temperature and the third detected temperature is still large, it is determined that the internal-engine-environment thermal bulb has a fault.
Taking the fault detection of the external unit environment temperature sensing bulb as an example, after the air conditioner detection device is connected with the external unit of the air conditioner, the external temperature sensing bulb is connected to the terminal of the detection device, and the external temperature sensing bulb is placed outdoors where the external unit is located, so as to detect the outdoor environment temperature where the external unit is located. As shown in fig. 3, after the detection device is powered on, the detection device first obtains a detection temperature of the external machine environment thermal bulb as a first detection temperature, and obtains a detection temperature of the external thermal bulb as a second detection temperature; then, the detection equipment judges whether the absolute value of the difference value between the first detection temperature and the second detection temperature is smaller than a first preset threshold value, and when the absolute value of the difference value between the first detection temperature and the second detection temperature is smaller than the first preset threshold value, the error between the detection temperature of the external machine environment temperature sensing bulb and the detection temperature of the external machine environment temperature sensing bulb is small, the detection temperature of the external machine environment temperature sensing bulb is correct, namely the external machine environment temperature sensing bulb works normally; when the absolute value of the difference value between the first detection temperature and the second detection temperature is not smaller than a first preset threshold value, the error between the detection temperature of the external environment temperature sensing bulb and the detection temperature of the external environment temperature sensing bulb is larger, and the detection temperature of the external environment temperature sensing bulb is incorrect, namely the external environment temperature sensing bulb is determined to be in fault.
In the above process, in order to perform fault detection more accurately, when the absolute value of the difference between the first detected temperature and the second detected temperature is not less than the first preset threshold, further obtaining an AD voltage value corresponding to the external machine environment thermal bulb, based on the AD voltage value, the detection device searches a preset table for a temperature value corresponding to the AD voltage value as a third detected temperature, and then determines whether the absolute value of the difference between the first detected temperature and the third detected temperature is less than the first preset threshold, and when the absolute value of the difference between the first detected temperature and the third detected temperature is not less than the first preset threshold, that is, when the error between the first detected temperature and the third detected temperature is still large, it is determined that the external machine environment thermal bulb has a fault.
And (3) detecting faults of the inner tube temperature sensing bulb, the outer machine air suction temperature sensing bulb and the outer machine exhaust temperature sensing bulb, and if accurate detection is required, fixing the outer temperature sensing bulb of the detection equipment on a corresponding pipeline. When the temperature of the inner pipe is detected, the inner pipe needs to be close to the inner machine pipeline as much as possible, when the temperature of the outer pipe is detected, the outer machine pipeline needs to be close to the outer machine pipeline as much as possible, the detection error can be reduced, and the detection method is the same as that of the inner machine environment temperature sensing bulb and that of the outer machine environment temperature sensing bulb.
The second mode is that the initial detection temperature of the target thermal bulb is obtained; after the air conditioner to be detected operates for a first preset time period, acquiring the current detection temperature of the target thermal bulb; judging whether the absolute value of the difference value between the initial detection temperature and the current detection temperature is greater than a second preset threshold value or not; and when the absolute value of the difference value between the initial detection temperature and the current detection temperature is not greater than the second preset threshold value, determining that the target temperature sensing bulb has a fault.
Specifically, as shown in fig. 4, after the detection device is connected to the internal unit or the external unit through a communication line, initial temperature data T1 is obtained, initial time data T1 is recorded and stored in data T3, a group of detected temperature values T2 is obtained after the air conditioner is operated for a period of time T, whether the temperature T1 detected in front is changed from the temperature T2 detected in back is determined, if the temperature values detected in front and back are not equal, a second group of detected temperature T2 values are stored in the first group of detected temperature T1, after a period of time T is waited, the difference between the second group of data and the initial value T3 is determined, if the values are smaller, detection is continued, multiple groups of data are detected for comparison, and the second group of detected temperature T2 values are stored in the first group of detected temperature T1 continuously until the absolute value of the difference between the two groups of temperature data exceeds an error temperature Δ T; if the total accumulated waiting time delta t exceeds the set maximum value, the resistance value of the temperature sensing bulb can be changed, and the temperature sensing bulb is preliminarily judged to be not completely damaged and can work normally.
The difference value of the initial temperature T3 and the latest detected temperature T2 is that after the normal air conditioner is started for cooling or heating and operates for a period of time, if the thermal bulb is normal, the resistance value of the thermal bulb is increased or decreased along with the temperature change of the air conditioning system, the temperature value corresponding to the real-time detection T2 is increased or decreased, and the resistance value of the thermal bulb is increased or decreased along with the temperature change, so that the thermal bulb is proved to be normal; if the temperature sensing bulb is damaged, the temperature sensing bulb does not change along with the change of the system temperature or the change amplitude is small, and the temperature sensing bulb is proved to be abnormal; the detection device only needs to judge whether the temperature fed back by the controller changes or not, the temperature fed back by the air conditioner changes after the air conditioner works for a period of time, and whether the temperature changes according to requirements or not is judged (for example, after the air conditioner works for a period of time, the temperatures of the inner ring and the inner pipe become lower, and after the air conditioner works for a period of time, the temperatures of the inner ring and the inner pipe become higher).
The detection principle of the second mode is as follows: when the temperature sensing bulb is normal, the temperature of the air conditioner is increased or decreased after the air conditioner runs for a period of time, the resistance of the temperature sensing bulb is increased or decreased, the main controller samples the voltage value between the temperature sensing bulb and the voltage dividing resistor, and the table is looked up to obtain the temperature corresponding to the voltage value; if the temperature sensing bulb is damaged, the resistance value does not change along with the temperature change, at the moment, the inner machine or the outer machine does not report faults, the detection equipment judges whether the temperature changes or not by acquiring the array temperature, if the air conditioner runs for a long time, the temperature value does not change, the temperature sensing bulb is possibly damaged, and after-sales personnel are prompted to replace the temperature sensing bulb. If the resistance values of the temperature sensing bags are not changed in the overtime, the temperature sensing bags are proved to be abnormal, the resistance values of the inner pipe, the inner ring and the outer pipe can be changed after the normal air-conditioning system works, and the controller main chip looks up the table to obtain a corresponding temperature value after the resistance values are changed; the controller main chip acquires temperature values, the temperature values are sent to the detection equipment through a communication line, the detection equipment compares the front temperature value and the rear temperature value to judge whether the front temperature value and the rear temperature value are changed, if the front temperature value and the rear temperature value are changed, more temperature values are acquired, if only one temperature value is acquired, the judgment is normal, the possible error is larger, more judgment is performed, and the error is smaller; therefore, a certain error value exists when the temperature value to be sampled last is set to be higher than the temperature value just after the air conditioner is started.
In this embodiment, when the air conditioner detection device detects a fault of a motor in an air conditioner, the following method may be adopted: setting the rotating speed of the motor so that the motor operates according to the set rotating speed; after the motor operates for a second preset time period, acquiring the current actual rotating speed of the motor; judging whether the absolute value of the difference value between the set rotating speed and the current actual rotating speed is smaller than a third preset threshold value or not; and when the absolute value of the difference value between the set rotating speed and the current actual rotating speed is not less than the third preset threshold value, determining that the motor fails.
In order to detect the motor fault more accurately, in this embodiment, the setting the rotation speed of the motor so that the motor operates at the set rotation speed includes: setting the rotating speed of the motor for multiple times so that the motor sequentially operates according to the set rotating speed; then the process of the first step is carried out,

the determining that the motor is faulty comprises: and when the absolute value of the difference value between the set rotating speed and the current actual rotating speed is not less than the third preset threshold value, determining that the motor fails.
In order to set the rotation speed of the motor more simply and efficiently so as to further accurately detect the motor fault, the method of this embodiment further includes: and acquiring the maximum rotating speed value and the minimum rotating speed value which can be reached by the motor, so that the rotating speeds of the motor which are arranged for multiple times are arranged in an arithmetic progression, the first item of the arithmetic progression is the minimum rotating speed value, and the last item of the arithmetic progression is the maximum rotating speed value.
When the air conditioner detection device is provided with a rotating speed detection circuit, the current actual rotating speed of the motor is obtained after the motor runs for a second preset time period, and the method comprises the following steps: after the motor runs for a second preset time period, acquiring the current actual rotating speed of the motor through the rotating speed detection circuit; the rotating speed detection circuit is electrically connected to a motor feedback signal line of the controller of the air conditioner to be detected, and specifically, the rotating speed detection circuit is connected to the motor feedback signal line of the controller of the air conditioner to be detected through a detection line.
Or, when the above rotation speed detection circuit is not used, acquiring the current actual rotation speed of the motor after the motor operates for a second preset time period includes: after the motor runs for a second preset time period, acquiring the number of pulses of a motor feedback signal sampled by a controller of the air conditioner to be detected; and calculating to obtain the current actual rotating speed of the motor based on the number of the feedback signal pulses of the motor.
Specifically, as shown in fig. 5, if the motor feedback signal detection circuit of the detection device is used, the detection device establishes communication with the internal unit or the external unit (the communication pin seat of the internal unit or the external unit is connected through the communication wire on the terminal), the motor pulse detection terminal of the detection device is connected with the motor feedback signal wire on the controller motherboard through the connection wire, the controller and the detection device can simultaneously obtain the motor feedback signal (one end of the connection wire of the detection device is connected with the motor, the other end is connected with the controller, and the motor feedback signal wire can be simultaneously obtained), the power-on machine is powered on, after the communication is established, all the rotation speed values of the motor are obtained, and the maximum value and the minimum value of the rotation speed are obtained by the detection device through comparisonAnd the detection equipment needs to detect the regulation condition of the rotating speeds of a plurality of groups of motors, and the rotating speed is increased at a fixed rate from the minimum rotating speed until the rotating speed is increased to the maximum rotating speed, so that whether the regulation of the rotating speed of the motor is normal or not is conveniently judged. After the detection equipment establishes communication with the internal machine or the external machine, the rotating speed V of the motor is set (the initial value is V)min) Waiting for a period of time t, the detection equipment obtains the current actual rotating speed V of the motor through a rotating speed detection circuitfThe controller adjusts the rotating speed of the motor in real time, the rotating speed has certain fluctuation, the requirement can be met by detecting the fluctuation of the rotating speed of the motor in a certain range in real time, and the V-V of the set rotating speed and the feedback rotating speed of the motor is judgedfError is at VbWithin the range, the set rotating speed is continuously increased to V + delta V according to a certain rotating speed change rate delta V, the V-V is sent to the controller through the communication wire, and after a certain time t, the V-V of the set rotating speed of the motor and the feedback rotating speed is continuously judgedfIf the error is in a certain range, the rotating speed is continuously increased according to a certain change rate delta V until the rotating speed of the motor is adjusted to the target rotating speed Vmax(the numerical value needs to be set according to the maximum practical operable rotating speed of the motor), the rotating speed of the motor is normally adjusted; if the difference between the current actual rotating speed of the motor and the set rotating speed is judged to be larger for one time, the judgment is continued after waiting for a period of time t, and if the total time for waiting for the motor to stabilize the rotating speed exceeds tmaxIf the motor is abnormal in speed regulation, the motor is quitted from the speed regulation, and the motor is determined to be in fault.
If the rotating speed of the motor is detected, a rotating speed detection circuit of the detection equipment is not adopted, or the detection equipment does not have the rotating speed detection circuit, namely a detection line of a motor feedback signal detection circuit of the detection equipment is not connected with an outer machine motor feedback signal line, after the detection line is communicated with the controller, the number of pulses of a motor feedback signal sampled by the controller is obtained, and the actual running rotating speed V of the motor is calculated through the number of pulses of the feedback signalfJudging the set rotating speed V of the motor and the feedback signal rotating speed VfWhether the error between is VbWithin the range, if the rotation speed is within the range, the detection equipment continues to increase the set rotation speed V at a fixed rotation speed change rate delta V, and continues to acquire a feedback signal of the motor through the communication line until the motor is powered onThe set rotating speed of the machine reaches the target value Vmax(ii) a If the obtained motor feedback signal rotating speed has large fluctuation or is far away from the target rotating speed, the judgment is carried out after the waiting time t is prolonged, if the rotating speed of the motor cannot be stable, and if the total waiting time exceeds tmaxAnd if the motor speed is abnormal, the motor speed is not regulated, and the motor is determined to be in fault.
