Detailed ways

Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

The communication method for the hook inclination detection device provided by the present invention can be applied to the application environment shown in FIG. 1 . As shown in FIG. 1 , the base station 102 communicates with the hook inclination detection device 104 configured to detect the inclination angle of the horizontal portion 106 of the hook to obtain the inclination angle of the hook portion 108 . Specifically, the hook inclination detection device 104 sends the 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 hook inclination detection device to the hook inclination detection device in response to receiving the inclination data. 104 sends a response signal; when the number of times the hook inclination detection device 104 does not receive the response signal reaches the first preset number of times, the hook inclination detection device 104 sends the detected inclination angle to the base station 102 at a second preset time interval data, the second preset time interval is greater than the first preset time interval, and the hook inclination detection device 104 does not perform the operation of inclination detection within the second preset time interval.

Fig. 2 schematically shows a schematic flowchart of a communication method used in a hook inclination detection device in an embodiment of the present invention. As shown in Figure 2, in the embodiment of the present invention, a communication method for the hook inclination detection device is provided, the hook inclination detection device communicates with the base station, and this method is applied to the processing of the hook inclination detection device Taking a device as an example for illustration, the communication method may include the following steps:

Step S202, sending the inclination data detected by the hook inclination detection device to the 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 the length of time between which the hook inclination detection device is set in advance to send the inclination data to the base station. Specifically, the timing time of the timer or the timing unit can be modified according to the actual situation, thereby adjusting the first preset time. As for the specific parameters of the interval, the first preset time interval may be set to 6 seconds, for example. The inclination data is the inclination information of the horizontal part of the hook. Since the hook inclination detection device is arranged above the horizontal part of the hook, it can detect the inclination angle of the horizontal part of the hook. The base station is the signal receiving base station or gateway, which can receive the inclination data of the horizontal part of the hook detected by the hook inclination detection device through wireless communication, so as to send the inclination data of the horizontal part of the hook to the main control of the tower crane or crane device, the inclination data is processed by the main controller. Further, in the normal working state, if the base station receives the inclination data sent by the hook inclination detection device, it will send a response signal to the hook inclination detection device, indicating that it has received the data sent by the hook inclination detection device.

Specifically, the hook inclination detection device can detect the inclination angle of the horizontal part of the hook in real time, or it can be set to detect regularly, for example, the inclination detection is performed after the first preset time interval, and the processor of the hook inclination detection device can control the communication The module (for example, a radio frequency circuit) sends the detected inclination data to the base station according to the first preset time interval (for example, 6 seconds), and the hook inclination detection device is in a normal sleep state after the equipment is turned on. Understandably, when the base station is in the working state, it can receive the inclination data sent by the hook inclination detection device, and in response to receiving the inclination data, send a response signal to the hook inclination detection device, and the response signal can indicate its The inclination data has been received.

Step S204, when the number of times of not receiving a response signal reaches the first preset number of times, sending the detected inclination 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 time interval, and the hook inclination detection device does not perform inclination detection operation within the second preset time interval.

It can be understood that the first preset number of times is the number of times the preset hook inclination detection device has not received the response signal fed back from the base station, that is, the number of times the hook inclination detection device fails to send inclination data to the base station, for example, 100 times. The second preset time interval is the interval time length at which the hook inclination detection device set in advance sends the inclination data to the base station, and its length is greater than the first preset time interval. Specifically, the timing time of the timer or the timing unit can be modified according to actual conditions. Therefore, specific parameters of the second preset time interval are adjusted. The second preset time interval may be set to 3 minutes, for example, or other longer time intervals.

Specifically, after the hook inclination detection device sends the inclination data to the base station according to the first preset time interval, if the number of times of not receiving the response signal fed back by the base station reaches the first preset number of times, that is, the hook inclination detection device sends to the base station When the number of times that the inclination data fails reaches the first preset number of times (for example, 100 times), the processor can control the communication module (for example, a radio frequency circuit) to send its data to the base station according to the second preset time interval (for example, 3 minutes). Detected inclination angle data, at this time the hook inclination detection device is in a deep sleep state. The inclination detection is performed in the middle of the two preset time intervals (ie after the second preset time interval), so as to send the detected inclination data to the base station.

Fig. 3 schematically shows a flow diagram of the step of sending inclination data according to a first preset time interval in an embodiment of the present invention. As shown in Figure 3, in the embodiment of the present invention, sending the inclination data detected by the hook inclination detection device to the base station at the first preset time interval may include the following steps:

Step S302, sending the inclination data detected by the hook inclination detection device to the base station at a first preset time interval.

Specifically, the processor may control the communication module (for example, a radio frequency circuit) to send the detected inclination data to the base station at a first preset time interval (for example, 6 seconds).

Step S304, if no response signal from the base station is received, send the detected inclination data to the base station at a third preset time interval, wherein the third preset time interval is shorter than the first preset time interval.

It can be understood that the third preset time interval is the length of time interval for the preset hook inclination detection device to send the inclination data to the base station, and its length is shorter than the first preset time interval. Specifically, the timer or timing unit can be modified according to the actual situation. Timing time, so as to adjust the specific parameters of the third preset time interval. The third preset time interval can be set to 100 milliseconds, for example, or can 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 from the base station, it indicates that the base station may be in a non-working state or a power-off state or a shutdown state at this time. , at this time, the processor may control the communication module (for example, a radio frequency circuit) to send the detected inclination data to the base station at a third preset time interval (for example, 100 milliseconds) for retrying.

Step S306, determining that the number of times that no response signal is received reaches a second preset number of times, wherein the second preset number of times is smaller than the first preset number of times.

It can be understood that the second preset number of times is the number of times the hook inclination detection device is set in advance to send the inclination data to the base station for retrying according to the third preset time interval, for example, 3 times.

Specifically, when the number of retries reaches the second preset number of times (for example, 3 times) and the processor still does not receive the response signal fed back by the base station, the processor then controls the hook inclination detection device to enter a deep sleep state, that is Send the state of the detected inclination data to the base station with a second preset time interval (for example, 3 minutes), and the hook inclination detection device does not perform real-time detection of the inclination angle in the second preset time interval (for example, 3 minutes) operate.

In the embodiment of the present invention, by setting the third preset time interval and the second preset number of times, it is possible to retry when the inclination 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, send the current inclination data to the base station at a shorter time interval (ie, the third preset time interval), and when the number of retries reaches the second preset number of times and the response signal sent by the base station cannot be received all the time, Then enter the deep sleep state, that is, the state of sending inclination data to the base station according to the second preset time interval, which can reduce the current power consumption of the hook inclination detection device and improve the communication efficiency between the hook inclination detection device and the base station.

Fig. 4 schematically shows a flow diagram of a communication method for a hook inclination detection device in another embodiment of the present invention. As shown in Figure 4, in the embodiment of the present invention, a communication method for the hook inclination detection device is provided, the hook inclination detection device communicates with the base station, and the method is applied to the hook inclination detection device as an example For illustration, the communication method may include the following steps:

Step S403, the hook inclination detection device judges whether the timing time is reached.

Understandably, the timing time here refers to the timing time of the hook inclination detection device in a normal sleep state, for example, the timing time of the hook inclination detection device in a normal sleep state is 6s.

Specifically, if the timing time (for example, 6s) in the normal sleep state is reached, the hook inclination detection device enters step S404, otherwise returns to step S402.

Step S404, the hook inclination detection device sends status data to the base station.

Understandably, the status data may include hook inclination angle data, equipment status, communication quality and other data.

In step S405, the hook inclination detection device judges whether a response signal from the base station is received.

Specifically, if the hook inclination detection device receives the response signal from the base station, return to step S402; otherwise, enter step S406 for retry.

Step S406, the hook inclination detection device performs retry and judges whether to retry more than 3 times.

Specifically, when the hook inclination detection device does not receive the response signal from the base station, it enters the retry step, that is, it sends data to the base station within a short time interval, and the retry time interval is relatively short, for example, it can be 100ms, In the case of retrying more than 3 times and still not receiving a response signal, go to step S408, otherwise go to step S407.

Step S407, the hook inclination detection device is ready to retry.

In step S408, the hook inclination detection device judges whether it fails more than 100 times.

Specifically, the hook inclination detection device judges whether the number of times of sending data to the base station according to the timing time (for example, 6s) in the normal sleep state and not receiving a response signal exceeds 100 times, if it exceeds 100 times, enter step S409, otherwise return Step S402.

Step S409, the hook inclination detection device is in a deep sleep state.

Step S410, the hook inclination detection device judges whether the timing time is reached.

Understandably, the timing time here refers to the timing time of the hook inclination detection device in the deep sleep state, for example, the timing time of the hook inclination detection device in the deep sleep state is 3 minutes.

Specifically, if the timing time (for example, 3 minutes) in the deep sleep state is reached, the hook inclination detection device enters step S404, otherwise returns to step S409.

Step S420, end.

Understandably, at this moment, the hook inclination detection device is in the equipment shutdown state. In one example, when the user triggers the switch to shut down the equipment, the hook inclination detection device can only be in this state, and when the switch is not triggered, the hook inclination detection device will not end its work, and the above steps will be executed continuously process. That is to say, the equipment (that is, the hook inclination detection device) is generally in a normal sleep or deep sleep state, and generally does not shut down.

Specifically, when the hook inclination detection device is in normal sleep, the hook inclination detection device maintains the RTC clock inside the chip and monitors the hook inclination angle in real time.

When the hook inclination detection device is in deep sleep, the hook inclination detection device does not monitor the sensor data in real time. The radio frequency part processes low power consumption and only maintains the internal RTC clock of the chip. According to the internal RTC clock timing, it actively wakes up the device and actively asks the base station ( or gateway), if it receives a response from the signal receiving base station, it will enter a normal sleep state, and if it does not receive a response, it will continue to maintain a deep sleep state.

In one embodiment, the communication method for the hook inclination detection device may further include: receiving a standby instruction sent by the base station, and sending a response signal to the base station in response to receiving the standby instruction; and stopping the inclination detection action.

Understandably, the standby command is used to instruct the hook inclination detection device to stop working, for example to stop inclination detection.

Specifically, the processor receives the standby command issued by the base station, and sends a response signal to the base station in response to the receipt of the standby command by the hook inclination detection device according to the work command, that is, it indicates that the hook inclination detection device has received the signal from the base station. After receiving the standby instruction sent by the base station, the processor can control the angle sensor of the hook inclination detection device to stop the inclination detection action to enter the standby state.

In the embodiment of the present invention, the hook inclination detection device stops working only after the base station sends a standby command. The device does not need to be in the working state all the time, and can be turned off at any time, with short working time and low power consumption.

Step S504, the hook inclination detection device turns on the receiver and is in a receiving state.

Specifically, the base station (or gateway) may send activation instruction data, configuration parameter instructions, device status query instructions, standby instructions, and the like.

In step S505, the hook inclination detection device processes the instruction data, configuration instructions, query instructions and standby instructions issued by the base station. Step S506, the hook inclination detection device sends response data to the base station, closes receiving, and monitors the channel in real time.

At this point, the hook inclination detection device can return to the step of regularly sending data to the base station, specifically, the above step S202 can be continued to send the inclination data detected by the hook inclination detection device to the base station at the first preset time interval. Step, 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 fixed preset time intervals.

Fig. 6 schematically shows a structural block diagram of a hook inclination detection device in an embodiment of the present invention. As shown in Fig. 6, in an embodiment of the present invention, a hook inclination detection device 600 is provided, including:

The communication module 610 is configured to communicate with the base station.

Understandably, the communication module 610 may include but not limited to a radio frequency circuit or a low-power radio frequency chip, so as to realize wireless communication with a base station.

The angle sensor 620 is configured to detect an inclination angle.

Understandably, the angle sensor 620 can obtain the inclination angle information of the hook by detecting the inclination angle of the horizontal part of the hook.

The processor 630 is configured to: send the inclination data detected by the hook inclination detection device to the 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 ; When the number of times that the response signal is not received reaches the first preset number of times, the detected inclination data is sent 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 hook inclination detection device does not perform inclination detection during the second preset time interval.

The first preset number of times is the number of times the pre-set hook inclination detection device has not received the response signal fed back from the base station, that is, the number of times the hook inclination detection device fails to send inclination data to the base station, for example, 100 times. The second preset time interval is the interval time length at which the hook inclination detection device set in advance sends the inclination data to the base station, and its length is greater than the first preset time interval. Specifically, the timing time of the timer or the timing unit can be modified according to actual conditions. Therefore, specific parameters of the second preset time interval are adjusted. The second preset time interval may be set to 3 minutes, for example, or other longer time intervals.

Specifically, the angle sensor 620 can detect the inclination angle of the horizontal part of the hook in real time, or can be set to detect regularly, for example, detect the inclination after a first preset time interval, and the processor 630 of the hook inclination detection device can control the communication module 610 (for example, a radio frequency circuit) sends the detected inclination data to the base station at a first preset time interval (for example, 6 seconds).

Specifically, the processor may control the communication module (for example, a radio frequency circuit) to send the detected inclination data to the base station at a first preset time interval (for example, 6 seconds). After the hook inclination detection device sends inclination data to the base station according to the first preset time interval, if the processor does not receive the response signal from the base station, it indicates that the base station may be in a non-working state or a power-off state or a shutdown state at this time. The processor may control the communication module (for example, a radio frequency circuit) to send the detected inclination data to the base station at a third preset time interval (for example, 100 milliseconds) for retrying. When the number of retries reaches the second preset number of times (for example, 3 times) and the processor still does not receive the response signal fed back by the base station, the processor controls the hook inclination detection device to enter a deep sleep state, that is, the second The status of the detected inclination data is sent to the base station at a preset time interval (eg, 3 minutes), and the hook inclination detection device does not perform real-time detection of the inclination angle within the second preset time interval (eg, 3 minutes).

In one embodiment, the processor 630 is further configured to: receive an operation instruction sent by the base station, and send a response signal to the base station in response to receiving the operation instruction; and start an inclination detection action.

Understandably, the communication module may include but not limited to a radio frequency circuit or a low-power radio frequency chip, so as to realize wireless communication with the base station. The angle sensor can obtain the inclination angle information of the hook by detecting the inclination angle of the horizontal part of the hook. The work order is used to instruct the hook inclination detection device to start working, for example, to perform inclination detection.

Specifically, the processor 630 can passively receive the work order actively sent by the base station, and send a response signal to the base station in response to the receipt of the work order by the hook inclination detection device according to the work order, which means that the hook inclination detection device has received the work order. To the work order issued by the base station. After the processor receives the work instruction sent by the base station, it can control the angle sensor of the hook inclination detection device to start the inclination detection action, so as to enter the working state. Further, the processor 630 can also control the communication module 610 (for example, a radio frequency circuit) to send the detected inclination data to the base station according to the first preset time interval, that is, to continue to execute the above step S202, or to follow a fixed preset time interval The detected inclination data is sent to the base station at intervals (for example, 30 seconds), and the device is in a working state at this time. The above-mentioned hook inclination detection device starts to work only after the base station issues a work order, and the device does not need to keep working for 24 hours, and only works when it needs to work, with short working hours and low power consumption.

In one embodiment, the processor 630 is further configured to: receive a standby command sent by the base station, and send a response signal to the base station in response to receiving the standby command; and stop the inclination detection action.

Specifically, the processor 630 receives the standby command issued by the base station, and sends a response signal to the base station in response to the receipt of the standby command by the hook inclination detection device according to the work command, that is, it indicates that the hook inclination detection device has received the standby command from the base station. The issued standby command, after the processor receives the standby command sent by the base station, can control the angle sensor of the hook inclination detection device to stop the inclination detection action, so as to enter the standby state.
