Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a diagram schematically illustrating an application environment of a communication method for a hook inclination angle detection apparatus according to an embodiment of the present invention. The communication method for the hook inclination angle detection device provided by the invention can be applied to the application environment shown in fig. 1. As shown in fig. 1, the base station 102 is in communication with a hook inclination detection device 104, and the hook inclination detection device 104 is configured to detect an inclination angle of a horizontal hook portion 106 to obtain an inclination angle of a hook portion 108. Specifically, the hook inclination detection device 104 sends inclination data detected by the hook inclination detection device 104 to the base station 102 at a first preset time interval, and the base station 102 is configured to send a response signal to the hook inclination detection device 104 in response to receiving the inclination data; under the condition that the number of times that the hook inclination angle detection device 104 does not receive the response signal reaches a first preset number of times, the hook inclination angle detection device 104 sends the detected inclination angle data to the base station 102 at a second preset time interval, wherein the second preset time interval is greater than the first preset time interval, and the hook inclination angle detection device 104 does not perform inclination angle detection operation within the second preset time interval.
Fig. 2 is a schematic flow chart illustrating a communication method for the hook inclination angle detection apparatus according to an embodiment of the present invention. As shown in fig. 2, in an embodiment of the present invention, a communication method for a hook inclination angle detection apparatus is provided, where the hook inclination angle detection apparatus communicates with a base station, and the communication method is described by taking a processor applied to the hook inclination angle detection apparatus as an example, and may include the following steps:
step S202, sending inclination data detected by the hook inclination detection device to a base station at a first preset time interval, wherein the base station is configured to send a response signal to the hook inclination detection device in response to receiving the inclination data.
It can be understood that the first preset time interval is a preset time interval length of the hook inclination angle detection device sending the inclination angle data to the base station, and specifically, the timing time of the timer or the timing unit may be modified according to an actual situation, so as to adjust a specific parameter of the first preset time interval, and the first preset time interval may be set to 6 seconds, for example. The inclination angle data is inclination angle information of the lifting hook horizontal part, and the lifting hook inclination angle detection device is arranged above the lifting hook horizontal part, so that the inclination angle condition of the lifting hook horizontal part can be detected. The base station is a signal receiving base station or a gateway, and can receive the inclination angle data of the lifting hook horizontal part detected by the lifting hook inclination angle detection device in a wireless communication mode, so that the inclination angle data of the lifting hook horizontal part is sent to a main controller of the tower crane or the crane, and the main controller processes the inclination angle data. Further, in a normal working state, if receiving the inclination data sent by the hook inclination detection device, the base station sends a response signal to the hook inclination detection device, indicating that the base station has received the data sent by the hook inclination detection device.
Specifically, the hook inclination angle detection device may detect the inclination angle of the horizontal portion of the hook in real time, or may be configured to perform timing detection, for example, perform inclination angle detection after a first preset time interval, and the processor of the hook inclination angle detection device may control the communication module (e.g., the radio frequency circuit) to send inclination angle data detected by the communication module to the base station according to the first preset time interval (e.g., 6 seconds), where the hook inclination angle detection device is in a normal sleep state after the device is turned on. Understandably, the base station may receive the inclination data sent by the hook inclination detection device when being in the working state, so as to send a response signal to the hook inclination detection device in response to receiving the inclination data, where the response signal may indicate that it has received the inclination data.
And step S204, under the condition that the times of not receiving the response signal reaches a first preset time, sending the detected inclination angle data to the base station at a second preset time interval, wherein the second preset time interval is greater than the first preset time interval, and the inclination angle detection device of the lifting hook does not perform the inclination angle detection operation within the second preset time interval.
It is understood that the first preset number of times is a preset number of times that the hook inclination detection device does not receive the response signal fed back by the base station, that is, the number of times that the hook inclination detection device fails to send the inclination data to the base station, for example, 100 times. The second preset time interval is an interval time length of sending inclination data to the base station by the hook inclination detection device, which is set in advance, and the length of the interval time is greater than the first preset time interval, and specifically, the timing time of the timer or the timing unit can be modified according to actual conditions, so as to adjust specific parameters of the second preset time interval, and the second preset time interval can be set to 3 minutes or other longer time, for example.
Specifically, after the hook inclination angle detection device sends inclination angle data to the base station according to a first preset time interval, if the number of times of not receiving a response signal fed back by the base station reaches a first preset number of times, that is, when the number of times of failure of the hook inclination angle detection apparatus to transmit inclination angle data to the base station reaches a first preset number of times (e.g., 100 times), the processor may control the communication module (e.g., rf circuit) to send its detected tilt angle data to the base station at a second predetermined time interval (e.g., 3 minutes), when the hook tilt angle detection device is in a deep sleep state, in the deep sleep state, the hook inclination angle detection device does not perform the inclination angle detection operation during the second time interval, and performing inclination detection in the middle of two adjacent second preset time intervals (namely after the second preset time intervals) to send the detected inclination data to the base station.
According to the communication method for the hook inclination angle detection device, the inclination angle data detected by the hook inclination angle detection device is sent to the base station according to the first preset time interval, when the number of times of not receiving the response signal of the base station reaches the first preset number of times, the inclination angle data is sent to the base station according to the second preset time interval, the length of the second preset time interval is larger than that of the first preset time interval, the longer sleep time of the hook inclination angle detection device can be ensured, the current power consumption of the hook inclination angle detection device is reduced, the hook inclination angle detection device does not perform hook inclination angle operation in the second preset time interval, the power consumption of the hook inclination angle detection device can be further reduced, and therefore the power consumption is reduced.
Fig. 3 is a schematic flow chart illustrating a step of transmitting tilt data according to a first preset time interval in an embodiment of the present invention. As shown in fig. 3, in the embodiment of the present invention, sending the tilt data detected by the hook tilt detection apparatus to the base station at the first preset time interval may include the following steps:
step S302, the inclination angle data detected by the hook inclination angle detection device is sent to the base station at a first preset time interval.
In particular, the processor may control the communication module (e.g., radio frequency circuitry) to transmit its detected tilt angle data to the base station at a first preset time interval (e.g., 6 seconds).
Step S304, in case that the response signal of the base station is not received, sending the detected tilt angle data to the base station at a third preset time interval, where the third preset time interval is smaller than the first preset time interval.
It can be understood that the third preset time interval is an interval time length of sending inclination data to the base station by the hook inclination detection device, which is set in advance, and the length of the interval time length is smaller than the first preset time interval, and specifically, the timing time of the timer or the timing unit may be modified according to an actual situation, so as to adjust a specific parameter of the third preset time interval, and the third preset time interval may be set to 100 milliseconds, for example, or may be set to other shorter times.
Specifically, after the hook inclination detection device sends the inclination data to the base station according to the first preset time interval, if the processor does not receive the response signal of the base station, indicating that the base station may be in an inactive state, a power-off state, or a power-off state at this time, the processor may control the communication module (e.g., the radio frequency circuit) to send the detected inclination data to the base station according to the third preset time interval (e.g., 100 milliseconds) for retry.
Step S306, determining that the number of times of not receiving the response signal reaches a second preset number of times, wherein the second preset number of times is smaller than the first preset number of times.
It is understood that the second preset number is the number of times, for example, 3 times, that the hook inclination detection device set in advance sends inclination data to the base station for retry at the third preset time interval.
Specifically, when the number of retries reaches a second preset number (e.g., 3) and the processor still does not receive a response signal fed back from the base station, the processor controls the hook inclination detection device to enter a deep sleep state, that is, a state of sending the detected inclination data to the base station at a second preset time interval (e.g., 3 minutes), and the hook inclination detection device does not perform the operation of detecting the inclination in real time within the second preset time interval (e.g., 3 minutes).
In the embodiment of the present invention, by setting the third preset time interval and the second preset time, retry may be performed when the tilt angle data is sent to the base station according to the first preset time interval but no response signal fed back by the base station is received, that is, the current tilt angle data is sent to the base station at a shorter time interval (that is, the third preset time interval), and when the retry time reaches the second preset time and the response signal sent by the base station cannot be received all the time, the state enters the deep sleep state, that is, the state where the tilt angle data is sent to the base station according to the second preset time interval, so that the current power consumption of the hook tilt angle detection apparatus may be reduced, and the communication efficiency between the hook tilt angle detection apparatus and the base station may be improved.
Fig. 4 is a schematic flow chart showing a communication method for the hook inclination angle detection apparatus according to another embodiment of the present invention. As shown in fig. 4, in an embodiment of the present invention, a communication method for a hook inclination angle detection apparatus is provided, where the hook inclination angle detection apparatus communicates with a base station, and the method is described as being applied to the hook inclination angle detection apparatus, where the communication method may include the following steps:
step S401 starts.
At this time, the hook inclination angle detection device is in the equipment starting state.
Step S402, the hook inclination angle detection device is in a normal sleep state.
Step S403, the hook inclination angle detection device determines whether the timing time is reached.
It is to be understood that the timing time herein refers to a timing time of the hook inclination detection device in the normal sleep state, for example, the timing time of the hook inclination detection device in the normal sleep state is 6 s.
Specifically, if the timing time (for example, 6S) in the normal sleep state is reached, the hook inclination detection device proceeds to step S404, otherwise returns to step S402.
Step S404, the hook inclination angle detection device sends state data to the base station.
Understandably, the status data may include hook tilt angle data, device status, communication quality, and the like.
Step S405, the hook inclination angle detection device judges whether a response signal of the base station is received.
Specifically, if the hook inclination angle detection device receives a response signal from the base station, the process returns to step S402, otherwise, the process proceeds to step S406 for retry.
Step S406, the hook inclination angle detection device retries and judges whether to retry for more than 3 times.
Specifically, the hook inclination angle detection device enters a retry step of sending data to the base station within a short time interval, where the retry time interval is short, for example, 100ms, when the retry time exceeds 3 times and the response signal is still not received, the process proceeds to step S408, otherwise, the process proceeds to step S407.
In step S407, the hook inclination detection device makes a retry.
Step S408, the hook inclination angle detection device judges whether the number of times of the failure exceeds 100 times.
Specifically, the hook inclination detection device determines whether the number of times of sending data to the base station and not receiving the response signal exceeds 100 times according to the timing time (for example, 6S) in the normal sleep state, and if the number of times exceeds 100 times, the step S409 is performed, otherwise, the step S402 is returned to.
Step S409, the hook inclination angle detection device is in a deep sleep state.
Step S410, the hook inclination angle detection device judges whether the timing time is reached.
Understandably, the timing time herein refers to the timing time of the hook inclination angle detection device in the deep sleep state, for example, the timing time of the hook inclination angle detection device in the deep sleep state is 3 min.
Specifically, if the timing time (for example, 3min) in the deep sleep state is reached, the hook inclination detection device proceeds to step S404, otherwise, returns to step S409.
And step S420, ending.
Understandably, the hook inclination angle detection device is in the off state of the equipment at the moment. In one example, when the user triggers a switch for turning off the device, the hook inclination angle detection device may be in the state, and when the switch is not triggered, the hook inclination angle detection device may not end the operation, and the above steps are continuously and cyclically executed. That is, the device (i.e., the hook angle detection means) is normally in a normal sleep or deep sleep state, and is not normally turned off.
Specifically, when the hook inclination angle detection device is in normal sleep, the hook inclination angle detection device maintains the functions of an RTC clock inside the chip and monitoring the inclination angle of the hook in real time.
When the lifting hook inclination angle detection device is in deep sleep, the lifting hook inclination angle detection device does not monitor sensor data in real time, the radio frequency part processes low power consumption, only an RTC clock in a chip is maintained, equipment is actively waken up according to the timing time of the RTC clock, a base station (or a gateway) is actively inquired, if a signal is received, the base station enters a normal sleep state, and if the signal is not received, the deep sleep state is continuously maintained. Thus, the device is typically in a normal sleep state or a deep sleep state, and is not typically powered off.
In the embodiment of the invention, the hook inclination angle detection device adopts a radio frequency technology of a wireless low-power consumption technology, and the wireless communication adopts spread spectrum and high receiving sensitivity, so that the communication distance can be increased and the receiving sensitivity can be improved. Further, by adopting low-power consumption sleep logic, when the signal receiving base station is not started, the hook inclination angle detection device is awakened at regular time according to the set internal RTC (real-time clock) time to actively send data, and when the response signal of the signal receiving base station is not received, the hook inclination angle detection device automatically enters a normal sleep state or a deep sleep state according to the set retry number and failure number. The device is in a timed sending mode, the device is in timed awakening work, the base station (or gateway) responds passively, the device can enter a deep sleep state, the power consumption is low, the communication process can only be initiated from the device terminal, the base station (or gateway) is in a passive receiving/responding mode, and the device works regularly 24 hours a day.
In an embodiment, before the hook inclination detecting device sends the inclination data detected by the hook inclination detecting device to the base station at a first preset time interval, the hook inclination detecting device may further include: receiving a working instruction sent by a base station, and sending a response signal responding to the received working instruction to the base station; and starting the inclination angle detection action.
Understandably, the operating instructions are used to instruct the hook inclination detection device to start operating, for example, to perform an inclination detection.
Specifically, the processor may passively receive a work instruction actively sent by the base station, and send a response signal in response to the hook inclination angle detection device receiving the work instruction to the base station according to the work instruction, that is, the hook inclination angle detection device has received the work instruction issued by the base station. After receiving the working instruction sent by the base station, the processor can control the angle sensor of the hook inclination angle detection device to start inclination angle detection action and enter a working state, namely a state of sending inclination angle data to the base station at regular time. Specifically, the processor may continue to perform the step S202, that is, the step of sending the inclination data detected by the hook inclination detection device to the base station at a first preset time interval, and in some embodiments, the hook inclination detection device may also send the inclination data detected by the hook inclination detection device to the base station at a fixed preset time interval.
In the embodiment of the invention, the hook inclination angle detection device starts to work only after the base station sends the working instruction, the equipment does not need to keep working for 24 hours, and only works in the time needing working, so that the working time is short, and the power consumption is low.

Fig. 6 is a block diagram schematically showing the structure of a hook inclination angle detection device according to an embodiment of the present invention. As shown in fig. 6, in an embodiment of the present invention, there is provided a hook inclination angle detection apparatus 600 including:
a communication module 610 configured to communicate with a base station.
Understandably, the communication module 610 may include, but is not limited to, a radio frequency circuit or a low power consumption radio frequency chip to enable wireless communication with a base station.
An angle sensor 620 configured to detect a tilt angle.
Understandably, the angle sensor 620 detects the inclination of the horizontal portion of the hook, so that the inclination information of the hook can be obtained.
A processor 630 configured to: sending inclination data detected by the hook inclination detection device to a base station at a first preset time interval, wherein the base station is configured to send a response signal to the hook inclination detection device in response to receiving the inclination data; and under the condition that the times of not receiving the response signals reach the first preset times, sending the detected inclination angle data to the base station at a second preset time interval, wherein the second preset time interval is greater than the first preset time interval, and the operation of detecting the inclination angle of the lifting hook inclination angle detection device is not carried out within the second preset time interval.
It can be understood that the first preset time interval is a preset time interval length of the hook inclination angle detection device sending the inclination angle data to the base station, and specifically, the timing time of the timer or the timing unit may be modified according to an actual situation, so as to adjust a specific parameter of the first preset time interval, and the first preset time interval may be set to 6 seconds, for example. The inclination angle data is inclination angle information of the lifting hook horizontal part, and the lifting hook inclination angle detection device is arranged above the lifting hook horizontal part, so that the inclination angle condition of the lifting hook horizontal part can be detected. The base station is a signal receiving base station or a gateway, and can receive the inclination angle data of the lifting hook horizontal part detected by the lifting hook inclination angle detection device in a wireless communication mode, so that the inclination angle data of the lifting hook horizontal part is sent to a main controller of the tower crane or the crane, and the main controller processes the inclination angle data. Further, in a normal working state, if receiving the inclination data sent by the hook inclination detection device, the base station sends a response signal to the hook inclination detection device, indicating that the base station has received the data sent by the hook inclination detection device.
The first preset number of times is the number of times that the hook inclination detection device does not receive the response signal fed back by the base station, that is, the number of times that the hook inclination detection device fails to send inclination data to the base station, for example, 100 times. The second preset time interval is an interval time length of sending inclination data to the base station by the hook inclination detection device, which is set in advance, and the length of the interval time is greater than the first preset time interval, and specifically, the timing time of the timer or the timing unit can be modified according to actual conditions, so as to adjust specific parameters of the second preset time interval, and the second preset time interval can be set to 3 minutes or other longer time, for example.
Specifically, the angle sensor 620 may detect the inclination angle of the horizontal portion of the hook in real time, or may be configured to detect the inclination angle at regular time, for example, after a first preset time interval, and the processor 630 of the hook inclination angle detection apparatus may control the communication module 610 (e.g., a radio frequency circuit) to send the detected inclination angle data to the base station according to the first preset time interval (e.g., 6 seconds), where the hook inclination angle detection apparatus is in a normal sleep state after the device is turned on. Understandably, the base station may receive the inclination data sent by the hook inclination detection device when being in the working state, so as to send a response signal to the hook inclination detection device in response to receiving the inclination data, where the response signal may indicate that it has received the inclination data.
After the hook inclination angle detection device sends inclination angle data to the base station according to a first preset time interval, if the times of not receiving a response signal fed back by the base station reach a first preset time, that is, when the number of times of failure of the hook inclination angle detection apparatus to transmit inclination angle data to the base station reaches a first preset number of times (e.g., 100 times), the processor 630 may control the communication module 610 (e.g., rf circuit) to transmit the detected tilt angle data to the base station at a second preset time interval (e.g., 3 minutes), when the hook tilt angle detection device is in a deep sleep state, in the deep sleep state, the angle sensor 620 does not operate the inclination detection during the second time interval, and performing inclination detection in the middle of two adjacent second preset time intervals (namely after the second preset time intervals) to send the detected inclination data to the base station.
Above-mentioned lifting hook inclination detection device, through the inclination data that sends lifting hook inclination detection device to the basic station according to first preset time interval and detect, when the number of times that does not receive the answer signal of basic station reaches first preset number of times, according to second preset time interval to base station transmission inclination data, the length of second preset time interval is greater than the length of first preset time interval, can guarantee that lifting hook inclination detection device's dormancy time is longer, reduce lifting hook inclination detection device's current consumption, and lifting hook inclination detection device does not carry out the operation at lifting hook inclination in second preset time interval, can further reduce lifting hook inclination detection device's power consumption, thereby reduce the power consumption.
In one embodiment, the processor 630 is further configured to: sending inclination angle data detected by a hook inclination angle detection device to a base station at a first preset time interval; under the condition that a response signal of the base station is not received, sending the detected inclination angle data to the base station at a third preset time interval, wherein the third preset time interval is smaller than the first preset time interval; and determining that the number of times of not receiving the response signal reaches a second preset number of times, wherein the second preset number of times is less than the first preset number of times.
It can be understood that the third preset time interval is an interval time length of sending inclination data to the base station by the hook inclination detection device, which is set in advance, and the length of the interval time length is smaller than the first preset time interval, and specifically, the timing time of the timer or the timing unit may be modified according to an actual situation, so as to adjust a specific parameter of the third preset time interval, and the third preset time interval may be set to 100 milliseconds, for example, or may be set to other shorter times. The second preset number is the number of times that the hook inclination detection device set in advance sends inclination data to the base station for retry at a third preset time interval, for example, 3 times.
In particular, the processor may control the communication module (e.g., radio frequency circuitry) to transmit its detected tilt angle data to the base station at a first preset time interval (e.g., 6 seconds). After the hook tilt angle detection apparatus sends tilt angle data to the base station according to the first preset time interval, if the processor does not receive a response signal of the base station, indicating that the base station may be in an inactive state, a power-off state, or a power-off state at this time, the processor may control the communication module (e.g., a radio frequency circuit) to send the tilt angle data detected by the communication module to the base station according to a third preset time interval (e.g., 100 milliseconds) for retry. When the number of retries reaches a second preset number (for example, 3 times) and the processor still does not receive a response signal fed back by the base station, the processor controls the hook inclination angle detection device to enter a deep sleep state, that is, a state of sending the detected inclination angle data to the base station at a second preset time interval (for example, 3 minutes), and the hook inclination angle detection device does not perform the operation of detecting the inclination angle in real time within the second preset time interval (for example, 3 minutes).
In the embodiment of the present invention, by setting the third preset time interval and the second preset time, retry may be performed when the tilt angle data is sent to the base station according to the first preset time interval but no response signal fed back by the base station is received, that is, the current tilt angle data is sent to the base station at a shorter time interval (that is, the third preset time interval), and when the retry time reaches the second preset time and the response signal sent by the base station cannot be received all the time, the state enters the deep sleep state, that is, the state where the tilt angle data is sent to the base station according to the second preset time interval, so that the current power consumption of the hook tilt angle detection apparatus may be reduced, and the communication efficiency between the hook tilt angle detection apparatus and the base station may be improved.
In one embodiment, the processor 630 is further configured to: receiving a working instruction sent by a base station, and sending a response signal responding to the received working instruction to the base station; and starting the inclination angle detection action.
Understandably, the communication module may include, but is not limited to, a radio frequency circuit or a low power consumption radio frequency chip to enable wireless communication with the base station. The angle sensor detects the inclination angle of the horizontal part of the lifting hook, so that the inclination angle information of the lifting hook can be obtained. The work instruction is used for instructing the hook inclination angle detection device to start working, such as inclination angle detection.
Specifically, the processor 630 may passively receive a work instruction actively sent by the base station, and send a response signal to the base station according to the work instruction, where the response signal is in response to the hook tilt detection device receiving the work instruction, that is, the response signal indicates that the hook tilt detection device has received the work instruction sent by the base station. After receiving the working instruction sent by the base station, the processor can control the angle sensor of the hook inclination angle detection device to start inclination angle detection so as to enter a working state. Further, the processor 630 may further control the communication module 610 (e.g., a radio frequency circuit) to transmit the detected tilt angle data to the base station at a first preset time interval, that is, to continue to perform step S202, or may transmit the detected tilt angle data to the base station at a fixed preset time interval (e.g., 30 seconds), where the apparatus is in an operating state. According to the lifting hook inclination angle detection device, the lifting hook inclination angle detection device only starts to work after a base station issues a work instruction, the equipment does not need to work for 24 hours, and only works in the time needing to work, so that the working time is short, and the power consumption is low.
In one embodiment, the processor 630 is further configured to: receiving a standby instruction sent by a base station, and sending a response signal responding to the received standby instruction to the base station; the tilt angle detection operation is stopped.
Understandably, the standby command is used to instruct the hook inclination detection device to stop working, for example, to stop performing inclination detection.
Specifically, the processor 630 receives a standby instruction issued by the base station, and sends a response signal in response to the hook inclination angle detection device receiving the standby instruction to the base station according to the working instruction, that is, the hook inclination angle detection device has received the standby instruction issued by the base station, and after receiving the standby instruction sent by the base station, the processor may control the angle sensor of the hook inclination angle detection device to stop the inclination angle detection operation, so as to enter a standby state.
In the embodiment of the invention, the hook inclination angle detection device stops working only after the base station issues the standby instruction, the equipment does not need to be in a working state all the time, can be shut down at any time, and has short working time and low power consumption.
