Field of the Invention The invention relates to an apparatus and method for detecting at least one rotation parameter of a rotating object. BACKGROUND OF THE INVENTION In engineering applications, feature extraction of a rotating object is primarily the direction of rotation of the object and the angular velocity of rotation of the object. There are three main types of detection schemes: The first one uses an encoder or a dedicated direction detector for detection. This solution can measure the speed more accurately and determine its direction in time, but this solution is costly and has special requirements for installation. Second, the scheme of using a combination circuit. This kind of scheme obviously does not meet the requirements of easy installation of the cylinder. Third, multiple sensors are used to collect information and determine the direction of rotation and the speed of calculation. This kind of solution is too expensive, complicated and difficult to install, and there is a large promotion difficulty. Especially in the concrete mixing drum, since the mixing quality of the concrete is closely related to the rotation direction and the rotation speed of the mixing drum, it is necessary to accurately judge the rotation direction and the rotation speed of the mixing drum, and the detection device and the detection method are preferably provided. It is low cost and installed. SUMMARY OF THE INVENTION In view of the deficiencies of the existing rotation parameter detecting scheme, the present invention proposes a new detecting device and detecting method, which can realize the detecting of the rotating direction and the rotating speed of the rotating object in a single tube manner. The device according to the present invention is a device for detecting at least one rotation parameter of a rotating object, characterized by comprising: detecting a sensor to be set with respect to a predetermined large distance of the rotating object; Three auxiliary detecting members are distributed on the rotating object, wherein at least two pitches, in particular at least three pitches, of the intermediate giant formed by two adjacent auxiliary detecting members of the at least three auxiliary detecting members are different The detecting sensor respectively generates a pulse signal in response to any of the auxiliary detecting means passing by the detecting sensor, and determines a rotation direction in the at least one rotation parameter of the rotating object according to different times in which the pulse signal appears. In this way, the detection of the direction of rotation can be achieved in a very simple manner. In a method aspect of the invention, a method for detecting at least one rotation parameter of a rotating object is provided, characterized in that it comprises the steps of: rotating a rotation with at least three auxiliary detection components The object is disposed at a predetermined distance from the detecting sensor, wherein at least two of the at least two of the at least three auxiliary detecting members are formed by at least two, especially at least three, which are different The detecting sensor respectively generates a pulse signal in response to any auxiliary detecting means passing by the detecting sensor; determining a rotation direction in the at least one rotation parameter of the rotating object according to different times in which each pulse occurs. By using the detection sensor and matching at least three auxiliary detection components, the rotation direction of the rotating object is judged according to different pulse timings generated by the sensor. According to a refinement of the invention, the relative rotation of the pulse intervals in the pulse interval sequences T 1 , T2, T3 Tn generated according to different times of occurrence of the respective pulses determines the direction of rotation in the at least one rotation parameter of the rotating object. That is, the direction of rotation in at least one rotation parameter of the rotating object is determined according to the relative size of each interval. According to a further development of the present invention, the at least three auxiliary detecting components respectively form a sequence of pitches SI, S2, S3, Sn-1, Sn, Sl, S2, ... in the counterclockwise direction and along the clockwise direction The sequence of the spacing of the directions Sn, Sn-l ... S3, S2, S1, Sn, Sn-l ..., the entire sequence or partial sequence in the pulse interval sequence T1, T2, T3 Tn emitted by the detecting sensor The detecting interval is determined by the detecting sensor to determine at least the relative size relationship of the at least three auxiliary detecting members in the counter pitchwise direction or the clockwise direction in the entire pitch sequence or the partial pitch sequence. The direction of rotation in a rotation parameter is counterclockwise or clockwise. In this manner, by the relative size of the intervals of the pulses generated by the detecting sensors in sequence, the size of the adjacent two auxiliary detecting members of the at least three auxiliary detecting members sequentially passing through the detecting sensors is reflected, thereby judging turn around. In a specific embodiment, the number of the auxiliary detecting components is three, and two adjacent auxiliary detecting components of the auxiliary detecting component form different first inter-S1 and second inter-S2 The third giant S3 forms a sequence of spacings S3, S2, S1, S3, S2 formed along the clockwise direction of the inter-large sequence S1, S2, S3, S1, S2, ... formed in a counterclockwise direction. In this way, the rotational direction and rotational speed of the rotating object can be detected with a minimum of the number of auxiliary detecting components. In the case of three auxiliary detecting components, the magnitude relationship of the three inter-large sums is S3>S2>S1, when the current time interval T1 and the previous time interval T2 and the relative size of the other preceding time interval T3 When the timing meets one of the following three conditions, Tl< Τ2 <Τ3 or Τ2 <Τ3<Τ1 or Τ3 <TKT2, it is determined that the rotation direction in the at least one rotation parameter is the counterclockwise rotation direction; when the current time interval T1 and the previous time interval Τ2 and the further forward time interval Τ3 are in the same size timing, the following three conditions are met. - When Τ3<Τ2<Τ1 or ΤΚΤ3<Τ2 or Τ2< ΤΚΤ3, the rotation direction of at least one rotation parameter is clockwise rotation direction.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be further described with reference to the accompanying drawings and embodiments: FIG. 1 shows a detection device in the case where six auxiliary detecting members are employed according to the present invention; FIG. 2 shows the use of three in accordance with the present invention. A detection device in the case of an auxiliary detection component. Fig. 3 shows the clockwise and counterclockwise timings respectively detected in the case of Fig. 2. Figure 4 shows the mounting device according to the invention mounted on a mixing drum. DETAILED DESCRIPTION OF THE INVENTION Figure 1 shows a detection device in the case where six auxiliary detecting members are employed in accordance with the present invention. The figure shows a rotating object 2, and a detecting device 1 for detecting the rotational direction and rotational speed of the rotating object, the detecting device 1 comprising six auxiliary detecting members L1-L6 and a detecting sensor 3 provided on the rotating object 2. The rotating object 2 is disposed at a predetermined distance with respect to the detecting sensor 3. The predetermined distance is set such that the detecting sensor 3 can detect the auxiliary detecting members L1 to L6 when the rotating object 2 rotates. At least two of the intervening giants formed by the adjacent two auxiliary detecting members in the auxiliary detecting members L1 to L6 are different. In Fig. 1, the six auxiliary detecting devices are respectively L1-L6, and the periodic spacing sequences S 1, S2, S3, S4, S5, S6, S 1, S2, S3... are formed in the counterclockwise direction, respectively. And forming a period in the clockwise direction 'I·生^M'Division's order 歹'J S6, S5, S4, S3, S2, S1, S6, S5.....where S1<S2<S3<S4 <S5<S6. Taking one cycle as an example, for example, the detecting sensor 3 generates six in response to the six auxiliary detecting components passing counterclockwise from the detecting sensor 3 (ie, the order of passing is LI, L6, L5, L4, L3, L2). The pulse signal, the first time interval T6 of the adjacent two pulses reflects the spacing S6 between L1 and L6, and the second time interval T5 of the adjacent two pulses reflects between L6 and L5. Giant S5, the third time interval T4 of the adjacent two flashes reflects the spacing S4 between L5 and L4, and the fourth time interval T3 of the adjacent two pulses reflects the spacing between L4 and L3. S3, the fifth time interval T2 of the two adjacent pulses reflects the spacing S2 between L3 and L2, and the sixth time interval T1 of the two adjacent pulses reflects between L2 and L1. Giant s 1. The relative size relationship of the time intervals in the non-listed time interval of the time interval 4 formed by the adjacent two punches of jt匕 reflects the relative size relationship of the pitches in the pitch sequence of the six auxiliary detecting sections. That is, the relative size of the pulse interval in the pulse interval timing T6-T1 is necessarily in accordance with the magnitude relationship of S1 < S2 < S3 < S4 < S5 < S6, that is, T1 < T2 < T3 < T4 < T5 < T6. It is therefore possible to use these monthly permanent signals to determine that the rotating object 2 is rotating in the counterclockwise direction of rotation. Conversely, these pulse signals can also be used to determine that the rotating object 2 is rotating in the clockwise direction of rotation. Of course, it is also possible to determine the direction of rotation of the rotating object using only one of the subsequences, for example, Τ3<Τ4<Τ5, instead of applying the entire sequence Τ1<Τ2<Τ3<Τ4<Τ5<Τ6. In the above-described plurality of cycles of rotation, the inter-substantial sequence S1, S2, S3, S4, S5, S6, S1, S2, S3, ... formed in the counterclockwise direction and the pitch sequence formed in the clockwise direction S6, S5, S4, S3, S2, S1, S6, S5, such subsequences such as S6, S1, S2 or Subsequences such as S 1, S6, and S5 determine the direction of rotation. The principle of detection is explained in further detail below with the aid of FIG. In FIG. 2, three auxiliary detecting members are shown. The central angle corresponding to the large inter-radius S1 between the first auxiliary detecting portion L1 and the second auxiliary detecting portion L2 is 60 degrees, and the second auxiliary detecting portion L2 is The central angle corresponding to the arc spacing S2 between the third auxiliary detecting members L3 is 120 degrees, and the central angle corresponding to the arc spacing S3 between the third auxiliary detecting portion L3 and the first auxiliary detecting portion L1 is 180 degrees, that is, S1<S2< S3. The spacings SI, S2, S3 between the auxiliary detecting members LI, L2, L3 are exemplified as long as the differences in the spacings are suitable for distinction. The clockwise timing generated according to Figure 2 is shown in the upper timing of Figure 3, and the counterclockwise timing is shown in the lower timing of Figure 3. Because of jib, it can be judged that it is rotated clockwise or counterclockwise according to these timings. As can be seen from FIG. 3, when the current time interval T1 and the previous time interval T2 and the further forward time interval T3 satisfy one of the following three conditions, Tl< Τ2 <Τ3 or Τ2 <Τ3<Τ1 or Τ3 <ΤΚΤ2, it is judged that the rotation direction in the at least one rotation parameter is the counterclockwise rotation direction. When the relative time series of the current time interval T1 and the previous time interval Τ2 and the other further time interval Τ3 meet one of the following three conditions: Τ3<Τ2<Τ1 or Τ1<Τ3<Τ2 or Τ2<Τ1<Τ3, Then, it is determined that the rotation direction in the at least one rotation parameter is a clockwise rotation direction. According to the following table, the specific judgment method can be reflected:

In the present invention, the rotational speed in the rotational parameter is calculated by counting the total pulse passing through the detecting sensor and dividing by the number of the auxiliary detecting members. Figure 4 shows the application of the detection device to the mixing drum 5 of the mixer truck according to the invention. The auxiliary detecting members L1-L6 are attached to the rotating end face 4 of the agitating tub 5, and the auxiliary detecting members L1-L6 are adjacent to the two auxiliary It is preferable to facilitate the spacing of the detecting members. The large distance between the detecting sensor 3 and the auxiliary detecting members L1 - L6 is such that the detecting end sensor 4 can detect the auxiliary detecting members L1 - L6 when the rotating end face 4 is rotated. It is preferred to use the mounting angle noted in Figure 2 (easy to distinguish). The inductive sensor used in the patent of the present invention can adopt various solutions as follows: The inductive sensor adopts a reflective photoelectric switch, and the auxiliary device is a reflecting plate. The principle is as follows: When the auxiliary device arrives, the inductive switch can receive the light emitted by its transmitter due to the reflection of the reflector, and the photoelectric switch has a signal output; once the illuminating plate is removed, the receiver does not receive light, the photoelectric switch No signal output. The inductive sensor uses a separate photoelectric switch for transmitting and receiving, and the auxiliary device is a generally opaque object. The principle is as follows: When the auxiliary device arrives, the light emitted by the transmitting side will be blocked so that the receiving side cannot receive the optical signal, and then the proximity of the object is sensed. When the object is removed, the receiver will resume receiving the signal sent by the sender. The inductive sensor uses an inductive proximity switch, and the auxiliary device is a common conductive metal. The principle is as follows: When a conductive object approaches an inductive switch that can generate an electromagnetic field, it will cause an eddy current inside the conductive object. This eddy current effect reacts to the inductive switch, which will change the internal circuit parameters of the switch, thereby identifying whether the conductive object is close to or not. , in turn, the switch is turned on or off to output different signals. The inductive sensor uses a capacitive proximity switch, and the auxiliary device is an ordinary object. The principle is as follows: The measurement of the inductive switch is usually one of the poles of the capacitor, and the other is the outer casing of the switch. The enclosure is usually grounded or connected to the outer casing of the equipment during the measurement. When an object moves toward the proximity switch, whether it is a conductor or not, because of its proximity, the dielectric constant of the capacitor will always change, so that the capacitance value changes, and the circuit state connected to the measuring head also occurs. The change, by which the switch can be controlled to be turned "on" or "off", thereby changing the state. The inductive sensor uses a Hall switch, and the auxiliary device is a magnetic object. The principle is as follows: When the magnetic object approaches the Hall switch, the Hall element of the inductive sensor changes the state of the internal circuit due to the Hall effect, thereby identifying the presence of a magnetic object nearby, thereby controlling the on or off of the switch. open. The inductive sensor uses an ultrasonic proximity switch or a proximity wave proximity switch, and the auxiliary device is an ordinary object. The principle is as follows: The ultrasonic wave switch utilizes the Doppler effect. When an object approaches, the reflected signal received by the proximity switch generates a Doppler shift, thereby recognizing the arrival of an object. The object of the present invention can be achieved by only one detecting member in the present invention. Of course setting More detection components are also possible.
