[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0034] A wireless detection device for a mine-used endless rope winch, such as Figure 1 As shown, it includes a wireless timing module 1, a wireless timing module 2, a wireless distance measurement module, a wireless tension measurement module, a wireless rotation speed measurement module, a wireless sound level measurement module and a wireless terminal installed on the endless rope winch;
[0035] All components of the device are equipped with ZigBee wireless modules, which are used to send the collected parameters wirelessly, and the wireless terminal receives the wireless signal and processes it for real-time display, and can also output curve graphs and reports, and provide early warning prompts.
[0036] Further, if Figure 2 and Figure 3 As shown, the wireless timing module 1 includes an isolated signal conditioning module of model TEM6650AN and a first controller of model C8051F350. The two sides of the 24v control switch of the on-site brake mechanism are connected in parallel to the connection port of the timer 1. R4, R6, and R8 divide the 12v voltage and then connect the voltage at both ends of R6 to the Sin+ and Sin- of the isolated signal conditioning module of TEM6650AN. At this time, the Sout+ pin outputs a high level and is connected to the AIN0.7 pin of the first controller through the voltage division of R7 and R10. The connection end of the wireless timer module 1 is connected to a section of insulated wire with an alligator clip, which is clamped on both sides of the on-site 24v control switch. Now after pressing the control switch, the AIN0.7 pin of the first controller detects a high level, and the internal timer of the single-chip microcomputer starts timing and sends data to the wireless terminal.
[0037] Further, if Figure 4 and Figure 5As shown, the wireless timing module 2 includes a single-channel 2-input AND gate integrated chip of model SN74LVC1G08DBVR and a second controller of model GD32E230C8T6. The brake and working gates of the on-site infinite rope winch are connected to the timer 2 connection port through alligator clip wires, and one side of the port is pulled up to a high level and connected to the single-channel 2-input AND gate integrated chip of SN74LVC1G08DBVR. The Y pin output S+ of the integrated chip is connected to the PB1 pin of the second controller of GD32E230C8T6. When the control switch is pressed on site, the brake and the working brake just touch the two connecting wires, the pull-up pin B of the integrated chip of the single-channel 2-input AND gate of SN74LVC1G08DBVR is pulled low, and the output pin Y outputs a high level to the PB1 pin of the second controller. When the high level is received, the timing end signal is sent and the timing end data is sent to the wireless terminal. The wireless terminal then calculates the idling time based on the sent data of timer 1. The measured idling time should be within the safe idling time designed by the manufacturer. If the safe idling time is exceeded, it is easy to cause a braking safety accident.
[0038] Further, if Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the wireless distance measurement module includes an eddy current coil of model ZD-260, operational amplifiers of model LM258 and LM321G, an analog-to-digital conversion chip of model AD7799BRUZ-REEL, and a third controller of model HC32L130J8TA. The output signal of the eddy current coil of ZD-260 of the wireless distance measurement module is processed by the LM258 operational amplifier circuit to output a 0-5v voltage signal, and the voltage signal is output through the LM321G operational amplifier follower circuit and divided into a voltage A_SEN by R11 and R12. The A_SEN voltage signal converts the collected analog signal into a digital signal through the analog-to-digital conversion chip of AD7799BRUZ-REEL, and is connected to the third controller through the AD_DIN, AD_DOUT, AD_CS, and AD_SCLK pins. The wireless distance measurement module is fixed at the level of the brake disc to detect the distance to the working brake disc. When the brake is released, the brake shoe gap should not be greater than 2mm. If the brake shoe gap is too large, it may cause excessive lost motion time and long braking distance, which may cause safety accidents. At this time, the vehicle should be stopped immediately for inspection to ensure that the brake shoe gap is within a safe range.
[0039] Further, if Fig.10 and Fig.11As shown, the wireless tension measurement module includes a tension sensor of model FL34-20, an analog-to-digital converter of model HY3116, and a fourth controller of model stm32f030c6_c8t. The wireless tension measurement module connects the input and output pins IN+, IN-, OUT+, and OUT- of the tension sensor of FL34-20 to the analog-to-digital converter of HY3116, and the output of the analog-to-digital converter is connected to PA6 and PA7 of the fourth controller through I2C (HY_SCL and HY_SDA). The wireless tension measurement module is threadedly installed on the shuttle car of the infinite rope winch, and the wire rope pulling ear is directly threaded and fixed. The test is performed to detect the traction force during normal operation to see if the traction force is within the safe bearing capacity of the wire rope to prevent safety accidents caused by rope breaking.
[0040] Further, if Fig.12 and Fig.13 As shown, the wireless speed measurement module includes a photoelectric encoder of model GP1A71R, a low voltage and high speed four-way differential line driver of model AM26LV31CDR, and a fifth controller of model STM32F030C8T6. The intermittent light shielding disc installed on the speed disk shaft of the wireless speed measurement module sends intermittent light signals to the photoelectric encoder of GP1A71R, and the output pins of the photoelectric encoder are connected to the low voltage and high speed four-way differential line driver of AM26LV31CDR. The differential line output pulse signals U1-10, U1-11, U1-13, and U1-14 are connected to PB4, PB5, PB6, and PB7 of the fifth controller to read the pulse model and convert the speed / traction speed test. The speed wheel of the wireless speed measurement module is fixedly installed close to the wire rope, and rotates synchronously with the movement of the wire rope to measure the speed / traction speed of the infinite rope winch.
[0041] Further, if Fig.14 , Fig.15 and Fig.16 As shown, the wireless sound level measurement module includes a microphone of model GD-ZS, an operational amplifier of model OP2177, an audio codec of model AIC3254, and a sixth controller of model LPC2368FBD100. The microphone of the wireless sound level measurement module is connected to the operational amplifier signal amplification output YOUT4 and YOUT5 of OP2177, and connected to the audio codec of AIC3254. The decoder is connected to the PA8 and PA13 pins of the sixth controller through the I2C interface SCL and SDA. The wireless sound level module is installed at the position of the winch operator's head to detect noise. Under normal circumstances, the noise does not exceed 90dB (A). If the on-site noise exceeds this value, it should be considered that the endless rope winch may have a mechanical failure in the motor, transmission shaft or drive disk, and the winch should be stopped immediately for safety inspection.
[0042] Further, if Fig.17 As shown, the wireless timing module 1, the wireless timing module 2, the wireless distance measurement module, the wireless tension measurement module, the wireless rotation speed measurement module, the wireless sound level measurement module and the zigbee wireless module equipped with the wireless terminal include a high-performance wireless microcontroller of model JN5161A and a fully integrated front-end module of model RFX2401C. The zigbee wireless module transmits the data processed and collected by the module to the wireless terminal, and the wireless terminal analyzes the data received by the wireless module, and displays the collected data in the form of numerical values, graphics, and reports, and performs early warning prompts, etc.
[0043] For ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the utility model, which all fall within the protection scope of the utility model.
