Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
As shown in fig. 1, the present invention provides a method for automatically allocating station numbers to a single spindle detection system, where the single spindle detection system is configured to detect whether a yarn breaking occurs in a spinning frame, and includes a master station device and at least two slave station devices, where the master station device is connected to the slave station devices through a communication bus, and all the slave station devices are connected together in a serial manner, as shown in fig. 2, where the serial manner is: the output signal of the last slave station device is connected with the input signal of the next slave station device, and the input signal of the first slave station device in series is always high level. When the station number automatic allocation method is applied to the master station equipment, the method comprises the following steps:
step S110: after receiving the signal of automatic station number allocation, all the slave station devices are informed to enter a station number configuration mode in a broadcasting mode, all the slave station devices enter the configuration mode, all the slave station devices set the station numbers of the slave station devices as invalid station numbers, and output signals of the slave station devices are set as low levels.
The master station device periodically communicates with all the slave station devices, and when a response signal of a certain slave station device is not received within a preset time, the slave station device is judged to be abnormal, and a user is prompted to check the abnormality of the slave station device.
After a new slave station device is replaced, a station number does not need to be manually configured for the slave station device, and a user can send a signal for automatically allocating the station number to the master station device through a key. And after the master station equipment receives the signal, broadcasting that all the slave station equipment enters a station number configuration mode. And all slave station equipment receives the broadcast and then enters a station number configuration mode, sets the station number of the slave station equipment as an invalid station number, sets the output signal of the slave station equipment as low level, enters a waiting state, and does not process other signals irrelevant to the station number configuration.
It should be noted that, each single spindle detection system can calculate the number of the slave station devices of the single spindle detection system through the number of textile spindles of the spinning frame and the number of spindles detected by each slave station, that is, the number of the slave stations of each single spindle detection system is fixed, and the station number change rule of each slave station is also fixed, so that it can calculate which station numbers are valid and which station numbers are invalid. For example, for a 480-spindle spinning frame, two single-spindle detection systems are provided (the two single-spindle detection systems are distributed on two sides of the spinning frame), one slave station of each single-spindle detection system detects 12 spindles, and therefore each single-spindle detection system comprises 20 slave station devices. Assuming that the station numbers of 20 slave station devices of a single-ingot detection system are set by sequentially adding 1 to 1 with 1 as an initial station number, 20 station numbers of 1-20 are valid station numbers, and other station numbers are invalid station numbers.
Step S120: sending the broadcast signal carrying the effective station number to all the slave station equipment, and enabling all the slave station equipment to configure the station number according to the station number configuration strategy according to the broadcast signal; wherein the station number configuration policy is as follows: and when the slave station equipment judges that the input signal of the slave station equipment is in a high level and the station number of the slave station equipment is an invalid station number, configuring the valid station number carried by the broadcast signal as the station number of the slave station equipment.
The broadcast signal carrying the effective station number is a station number configuration signal, the master station device sends the effective station number to all the slave station devices through broadcasting, and all the slave station devices set the received effective station number as the station number of the slave station device only under the condition that the following two conditions are met simultaneously: (1) the self station number is an invalid station number; (2) the signal at the input end of the self-body is high level.
Step S130: inquiring whether the station number of the slave station equipment corresponding to the effective station number carried by the broadcast signal is successfully configured, and enabling the slave station equipment with the successfully configured station number to set the output signal of the slave station equipment to be at a high level after the slave station equipment sends a response signal with the successfully configured station number.
After the master station device sends the broadcast signal carrying the valid station number, the master station device sends a one-to-one inquiry signal by using the valid station number as a communication address, namely, inquires whether the station number of the slave station device configured with the valid station number is successfully configured. If the slave station device can receive the inquiry signal, namely the station number is successfully set, the slave station device directly returns a response signal of successful station number configuration, and then the slave station device also sets the output signal of the slave station device to be high level, so that the input signal of the next slave station device connected with the slave station device in series also becomes high level, and after the next time the valid station number sent by the master station is received, the slave station device of the next slave station can continue to configure the station number.
Note that the input signal of the first slave station device connected in series is always high.
Step S140: and if a response signal that the station number configuration is successful is received, generating a next effective station number according to a preset rule on the basis of the effective station number, sending the broadcast signal carrying the next effective station number to all the slave station equipment again, and repeatedly executing the process until a response signal that the station number configuration of the last slave station equipment is successful is received.
After receiving a response signal that the station number of the slave station equipment is successfully configured, continuing to configure the station number of the next slave station equipment until the station numbers of all the slave station equipment are configured, namely receiving a response signal that the station number of the last slave station equipment is successfully configured. And after receiving a response signal that the station number of the last slave station equipment is successfully configured, prompting the user that the station number is automatically allocated.
It should be noted that, after each slave device responds to the inquiry signal indicating whether the station number of the master device is successfully configured, the output signal of each slave device is set to be at a high level, that is, the input signal of the next slave device connected in series with the slave device is also changed to be at a high level, so that it is ensured that after the next master device sends the station number configuration signal, only one slave device can configure the station number.
Preferably, the effective station number carried by the broadcast signal carrying the effective station number sent for the first time is 1, and the preset rule is to successively add 1.
Step S150: and informing all slave station equipment to exit the station number configuration mode in a broadcasting mode.
After the station number configuration of all the devices is completed, the master device needs to notify all the slave devices to exit the station number configuration mode in a broadcast manner.
In a preferred embodiment, the method further comprises:
after inquiring whether the station number configuration of the slave station equipment corresponding to the effective station number carried by the broadcast signal is successful, if a response signal of successful station number configuration is not received in a preset time period, informing all the slave station equipment to exit a station number configuration mode in a broadcast mode, and prompting a user that the automatic station number allocation fails. The station number for which the assignment failed is the communication station number of the inquiry signal. For example, after transmitting the station number configuration signal with the station number 2 to all the devices, the inquiry signal is directly transmitted to the slave station device with the station number 2, and if the response signal is not received, the slave station device with the station number 2 is judged to fail to configure the station number, that is, the station number which is failed to be allocated is the station number 2.
In a preferred embodiment, the communication buses of the master device and the slave device are CAN buses. The CAN bus CAN realize rapid communication, and the station number of a slave station is configured only by 200-500 ms.
In a specific implementation of an automatic station number allocation method, after receiving an automatic station number allocation signal sent by a user, a master station device notifies all slave station devices to enter a station number configuration mode in a broadcast manner, and in order to reduce omission, the notification generally needs to be broadcast 3 times. And after receiving the notice, the slave station equipment enters a station number configuration mode. After the slave station enters the station number configuration mode, the station number of the slave station is cleared firstly, namely the station number is set to be invalid, then the output signal of the slave station is set to be 0, the slave station waits for the signal related to the station number configuration sent by the master station equipment, and in addition, the signal unrelated to the station number configuration is not processed.
Then the master station device configures station numbers for all the slave station devices in sequence, wherein the configuration mode is as follows: and sending the broadcast signal carrying the station number 1 to all the slave station equipment, and configuring the effective station number carried by the broadcast signal as the station number of the slave station equipment when all the slave station equipment judges that the input signal of the slave station equipment is 1 and the station number of the slave station equipment is an ineffective station number. After the first configuration broadcast signal transmitted by the master device, only the first slave device in the series meets the above condition (the input signal of the first slave device is always 1), and therefore the first slave device in the series configures its own station number as 1.
The master station equipment inquires whether the station number of the slave station equipment with the station number of 1 is successfully configured in a point-to-point mode, the output signal of the slave station equipment 1 is set to be 1 after the slave station equipment 1 directly responds to a signal that the station number is successfully configured, so that the input signal of the second slave station equipment connected in series with the slave station equipment is also changed to be 1, and after the master station transmits the broadcast signal configured by the station number for the second time, only the second slave station equipment connected in series meets the condition. And by analogy, the master station configures unique station numbers for all the slave station devices in sequence according to the mode, and then informs all the slave station devices to exit the station number configuration mode in a broadcasting mode.
It should be noted that, after the master device queries whether the station number of the corresponding slave device is successfully configured in a point-to-point manner, if a response signal indicating that the station number is successfully configured is not received within a predetermined time period, the master device prompts the user that the corresponding station number is unsuccessfully configured, and simultaneously notifies all the slave devices to exit the station number configuration mode.
The station number automatic distribution method of the single-spindle detection system does not need to manually set the station number, reduces the negative influence caused by the same station number due to human factors, and does not need a dial switch any more, thereby reducing the cost of products.

The station number automatic allocation method is applied to the slave station equipment and comprises the following steps:
step S210: after receiving signals of all slave station devices entering a station number configuration mode, the slave station devices enter the station number configuration mode, set the station numbers of the slave station devices as invalid station numbers, and set output signals of the slave station devices as low levels.
Step S220: after receiving a broadcast signal carrying a valid station number, when judging that an input signal of the station is in a high level and the station number of the station is an invalid station number, configuring the valid station number carried by the broadcast signal as the station number of the station.
