Background technology
At present on the oil field; Most oil pumper all has been equipped with motor protecting device; These motor protecting devices can be realized the protective effect to motor at current imbalance or when excessive basically, but find through after the application of long period, and this motor protector can not be in time after action sends report to the administrative staff of equipment; Can only wait until after administrative staff normally patrol and examine and just can carry out the fault recovery of equipment, influence the recovery time of equipment.
Summary of the invention
The technical problem of mentioning in order to solve in the background technology; The utility model provides a kind of motor protector; This kind motor protector has increased a long distance wireless radiating circuit on the basis of original structure; In case the motor protector action can in time remind administrative staff to handle to the scene to the long-range transmission Trouble Report of administrative staff.
The technical scheme of the utility model is: this kind motor protector; Comprise difference AD sampling circuit, cpu system, switching value input circuit, relay logic loop, human-machine interface module, LPF circuit units and power module etc., it is characterized in that: said motor protector also comprises a wireless signal transmission circuit that is made up of STM32F103C6T6 chip and APC240 chip; The data input pin of said STM32F103C6T6 chip is connected with the data output end of cpu system, and the input that transmits of said APC240 chip is connected with the data output end of STM32F103C6T6 chip.
In addition; On the such scheme basis; Can between said switching value input circuit and cpu system, be provided with the photoelectric isolating circuit that comprises luminous tube and photodiode, the switching signal of said switching value input circuit output outputs to the switching value signal input part of said cpu system through the optocoupler effect of photoelectric isolating circuit.
During practical implementation, said LPF circuit units adopts the Butterworth LPF chip, and said photoelectric isolating circuit adopts linear optical coupling HCNR200 chip.
The utlity model has following beneficial effect: this kind motor protector is owing to increased radio transmitter; When cutting off control loop when motor protector generation action in a single day; Cpu system will send the fault-signal sign indicating number to the STM32F103C6T6 chip; Whether the STM32F103C6T6 chip is distinguished under the identification of internal processes needs long-range transmission data, obtain recognition result after, carry out the teledata emission through the APC240 chip.Like this, the administrative staff that are positioned between control just can in time obtain the failure condition of equipment, thereby in time handle.
Description of drawings:
Fig. 1 is the composition sketch map of the utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
By shown in Figure 1; This all motor protector; Comprise difference AD sampling circuit, cpu system, switching value input circuit, relay logic loop, human-machine interface module, LPF circuit units and power module etc., its unique distinction is: said motor protector also comprises a wireless signal transmission circuit that is made up of STM32F103C6T6 chip and APC240 chip; The data input pin of said STM32F103C6T6 chip is connected with the data output end of cpu system, and the input that transmits of said APC240 chip is connected with the data output end of STM32F103C6T6 chip.
Between said switching value input circuit and cpu system, be provided with the photoelectric isolating circuit that comprises luminous tube and photodiode, the switching signal of said switching value input circuit output outputs to the switching value signal input part of said cpu system through the optocoupler effect of photoelectric isolating circuit.
In addition, on the such scheme basis, can select said LPF circuit units to adopt the Butterworth LPF chip, said photoelectric isolating circuit adopts linear optical coupling HCNR200 chip.
During practical implementation, said LPF circuit units adopts the Butterworth LPF chip, and said photoelectric isolating circuit adopts linear optical coupling HCNR200 chip.HCNR200 molded lines property optocoupler is made up of light-emitting diode, feedback light electric diode and output photodiode.When light-emitting diode passes through drive current, send infrared light as servo luminous flux.This light is radiated at respectively on feedback light electric diode and the output photodiode, and the feedback light electric diode absorbs the part of feedback light electric diode luminous flux, thereby produces Control current.The linear ratio of servo luminous flux that output current that the output photodiode produces and light-emitting diode send.The signal that HCNR200 is operated under the photoconductive pattern is the positive polarity input, positive polarity output.Need the size of the elementary amplifier input bias current of resistance adjustment in the buffer circuit, electric capacity plays feedback effect, filtering simultaneously the burr signal in the circuit, avoid the aluminum gallium arsenide light-emitting diode of HCNR200 to receive unexpected impact.
In addition, the signal of switching value input circuit input cpu system, cpu system is provided with three tunnel outputs, connects communication module, human-machine interface module MMI and relay logic loop and power module respectively.And also can be provided with photoelectric isolating circuit between cpu system and the relay logic loop, act on identical with the former.In addition; Communication module comprises ethernet communication interface, CAN Netcom communication interface and RS485 communication interface; Human-machine interface module comprises LCDs, keyboard and clearing lamp; Cpu system constitutes high performance 32-bit microprocessor CPU, jumbo ROM, RAM and Flash memory by 32-bit microprocessor CPU, RAM, ROM, Flash memory etc.; Will make cpu system have extremely strong data processing and registering capacity, can realize the fault data that various complex failure processing schemes are a large amount of with record.Recordable record ripple report is no less than 10 times in the Flash memory, and recordable event number is no less than 500 times.Operation configuration informations such as protection definite value also deposit in this memory, and these information all can not lost after the device power down.
The switching value input circuit open into amount be divided into inside open into the outside open into, inside open into employing DC24V open into, power supply is provided by the power module of the utility model, open into employing two-stage optical coupling isolation circuit the outside, realizes the direct incoming level of DC220V.
