In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
The embodiment of the application provides a safety helmet, as shown in fig. 1, the safety helmet comprises a safety helmet body and a high-voltage electric field early warning device arranged on the safety helmet body.
In one embodiment, the high-voltage electric field early warning device may include: a high-voltage electric field detection sensor F1, a microprocessor U2, a motor driver U7 and a motor M.
The high-voltage electric field detection sensor F1 is used for detecting a high-voltage electric field and outputting a high-voltage early warning signal after detecting the high-voltage electric field.
The microprocessor U2 is used for receiving the high-voltage early warning signal output by the high-voltage electric field detection sensor F1 and outputting a corresponding first driving control signal according to the high-voltage early warning signal.
The motor driver U7 is used for receiving the first drive control signal output by the microprocessor U2 and outputting a corresponding motor drive signal according to the first drive control signal.
The motor M is configured to receive a motor driving signal output by the motor driver U7, and perform a corresponding action according to the motor driving signal.
Optionally, in practical application, an amplifier U1 may be added to the helmet. The amplifier U1 is used for receiving the high-voltage early warning signal output by the high-voltage electric field detection sensor F1, amplifying the high-voltage early warning signal and generating a corresponding high-voltage early warning amplification signal.
The high-voltage early warning signal output by the high-voltage electric field detection sensor F1 is amplified by the amplifier U1, and the high-voltage early warning signal output by the high-voltage electric field detection sensor F1 can be converted into a corresponding direct-current voltage signal of 0-5V or 1-10V, so that the high-voltage early warning amplified signal processed by the amplifier U1 can meet the requirement of the microprocessor U2 on the input signal.
Accordingly, the above "the microprocessor U2 is used for receiving the high voltage early warning signal output by the high voltage electric field detection sensor F1, and outputting the corresponding first driving control signal according to the high voltage early warning signal" may be replaced by:
the microprocessor U2 receives the high-voltage early warning amplified signal output by the amplifier U1 and outputs a corresponding first driving control signal according to the high-voltage early warning amplified signal.
Optionally, except that the high-voltage early warning is output through the vibration of the motor M, the high-voltage electric field early warning can be output to the electric power overhaul worker in a sound early warning mode.
Specifically, a voice controller U6 and a speaker Y may be added to the helmet.
Correspondingly, after receiving the high-voltage early warning amplification signal output by the amplifier U1, the microprocessor U2 may further generate a corresponding second driving control signal according to the high-voltage early warning amplification signal.
The voice controller U6 can be used for receiving the second driving control signal output by the microprocessor U2 and outputting a corresponding voice driving signal according to the second driving control signal.
The speaker Y may be configured to receive the voice driving signal output by the voice controller output U6, and broadcast corresponding audio data according to the voice driving signal.
The electrical wiring and electrical equipment of each transformer substation in the electric power overhaul work are different in form, the familiarity degree of operation or overhaul personnel to field equipment is also different, personnel pass in and out and need check the safety measure of equipment one by one, and because the overhaul field is complicated, the earth connection installation has no indicating sign, and the denoter has no warning and informing function. The overhaul field management depends on the safety consciousness and the consciousness of personnel, no effective technical means is provided for reminding the overhaul workers of violation or negligence to inform, basically, the condition of the overhaul workers is monitored by monitoring by a working responsible person, and an effective intelligent detection method is not provided for solving the problem. The existing safety helmet has no alarming function and site safety informing function, and when negligence or misjudgment occurs, an electric shock (induction) accident caused by mistaken entering of a live interval or misoperation of an electrified line by an operator can occur, so that a serious accident is caused. To avoid the occurrence of human responsibility accidents, the management must be standardized, starting from the subtle points, and the customs clearance is controlled at multiple levels.
For this reason, in one embodiment of the present application, an antenna E1 and a wireless receiving circuit for collecting signals related to a warning board or a ground wire may be further added to the helmet.
Specifically, the antenna E1 is used to acquire a coded modulation wave signal output from the warning board or the ground line.
The wireless receiving circuit is used for receiving the coded modulation wave signals acquired by the antenna E1, extracting address codes in the coded modulation wave signals and sending the address codes to the microprocessor U2.
In practical applications, the wireless receiving circuit may include a code modulation wave receiver U8 and a multi-channel decoder U9.
Specifically, the encoding modulation wave receiver U8 may be configured to receive the encoding modulation wave signal acquired by the antenna E1, and send the encoding modulation wave signal to the multi-channel decoder U9.
The multi-channel decoder U9 may be configured to receive the coded modulated wave signal output by the coded modulated wave receiver U8, extract an address code in the coded modulated wave signal, and send the address code to the microprocessor U2.
Correspondingly, the microprocessor U2 is further configured to receive the address code output by the wireless receiving circuit, i.e., the multi-channel decoder U9, and verify whether the address code is incorrect according to the pre-stored address information.
When the address code is verified to be correct according to the pre-stored address information, the microprocessor U2 is further configured to output a corresponding third driving control signal according to the address code.
When the address code is verified to have errors according to the prestored address information, the microprocessor U2 does not process the address code any more, and the microprocessor U2 can feed back the information that the address code is verified to have errors or the address code is verified to have failures to the code modulation wave receiver U8 and the multi-channel decoder U9 in the wireless receiving circuit, so that the code modulation wave receiver U8 and the multi-channel decoder U9 in the wireless receiving circuit can obtain the code modulation wave signal in the working environment again according to the feedback information output by the microprocessor U2.
After verifying that the address code is correct according to the pre-stored address information and the microprocessor U2 outputs a corresponding third driving control signal according to the address code, the voice controller U6 is further configured to receive the third driving control signal output by the microprocessor U2 and output a corresponding voice driving signal according to the third driving control signal.
For the voice driving signal outputted according to the third driving control signal, the voice driving signal may be further transmitted to the speaker Y1, so that the speaker Y1 may broadcast corresponding audio data according to the voice driving signal.
Because in the safety helmet provided by the embodiment of the application, the content of the audio data needing to be broadcasted by the loudspeaker Y1 is more, a memory can be additionally arranged for storing the audio data corresponding to each voice driving signal.
In one embodiment, two memories, i.e., the memory U4 and the memory U5, may be added at the same time to store audio data, respectively, to form a redundant backup.
In fig. 1, the helmet body is omitted. Since the helmet provided by the embodiment of the present application is not an improved design of the helmet body, in order to highlight the invention of the embodiment of the present application, the helmet body is omitted in fig. 1.
As an example, the high-voltage electric field early warning device provided on the helmet body in the embodiment of the present application may be constructed according to the schematic circuit diagram shown in fig. 2.
The high-voltage electric field early warning device shown in fig. 2 comprises a high-voltage electric field detection sensor F1, an amplifier U1 (namely a signal level amplification processing module), a microprocessor U2, a clock chip U3, a memory U4, a memory U5, a motor driver U7, a motor M and other devices.
The working process of the high-voltage electric field early warning device shown in fig. 2 is as follows:
when electric power overhaul staff went into electrified interval or regional by mistake, the high voltage electric field detection sensor F1 in the safety helmet that this application embodiment provided detects high voltage electric field (be strong electric field signal) back, can output corresponding high-pressure early warning signal.
The high-voltage early warning signal output by the high-voltage electric field detection sensor F1 is subjected to signal level amplification processing by an amplifier U1, then is input to the 3 end of an I/O port of a microprocessor U2, and the microprocessor U2 is used for calculating, analyzing and verifying the high-voltage early warning amplified signal.
Specifically, the microprocessor U2 may confirm the data corresponding to the high-voltage warning amplifying signal, compare the data with a threshold stored in advance, and perform corresponding control according to the comparison result.
When the microprocessor U2 confirms that the data corresponding to the high voltage pre-warning amplification signal is greater than or equal to the corresponding threshold, the microprocessor U2 may output a high level through its P1.6I/O port 18, thereby controlling the motor driver U7 to start the motor M.
Specifically, the motor M may be a direct current vibration motor. Install the eccentric cam on direct current shock dynamo's motor shaft, the direction that the eccentric cam produced the centrifugal force constantly changes along with the rotation of eccentric cam to make direct current shock dynamo produce vibrations of great amplitude, make the electric power maintenance staff who misses and go into electrified interval or region wear the safety helmet produce vibrations of great amplitude, thereby make the electric power maintenance staff who misses and go into electrified interval or region in time perceive the high-voltage electric field risk, remind the electric power maintenance staff equipment region of mistake income electrified interval or region to have electricity from dangerous edge.
Meanwhile, the microprocessor U2 can also send a command for reading the operation voice played by the AD4 to the voice controller U6 (e.g., the serial port control voice module WTV010) through the P1.2I/O port 14.
Microprocessor U2 has port P04 as the CLK input and port P05 as the DI input. Port P04 and port P05 constitute a two-wire serial port control mode.
The microprocessor U2 controls the voice controller U6 (e.g., serial port control voice module WTV010) by sending data via CLK clock and DI data line to drive the speaker Y to emit audio prompt data "the device is powered on, do not come close".
Specifically, the U2 microprocessor is a single chip microcomputer composed of STC11F 01.
In fig. 2, C9 and R3 form the reset circuit of the microprocessor U2, and at the moment of power-on, the pin 1 at the reset terminal of the microprocessor U2 gets a high-level reset pulse due to the charging process of the power supply voltage to the C9, so that the microprocessor U2 enters an initial state.
The voice controller U6 (e.g. serial port control voice module WTV010) is a mass storage type voice module capable of repeatedly erasing and writing voice content, and can automatically recognize voice files and store 512 pieces of voice at most. The pin 7 is CLK input at P04, the pin 10 is DI input at P05, and the pin P04 and the pin P05 form a two-wire serial port control mode.
The P1.3I/O port 14 of the microprocessor U2 controls the CLK to send out a time pulse, the DI port is used for the control command of the data receiving voice address, and when the data is sent out, the 16-bit 2-system data corresponding to the voice file name needs to be sent out.
The MCU control terminal CLK signal of the microprocessor U2 is sent simultaneously with the DI signal, and the DI data is sent high before low. Without sending a code, CLK and DI are both asserted high. After the chip receives the instruction, the corresponding audio is read from the SD card and is output by the 4 and 5 ports of the chip, so that the music is played.
Once there is a change in the potential from the signal detected by the high voltage E-field detecting sensor F1 to the P3.1I/O port 3 terminal of the microprocessor U2, the microprocessor U2 enters a designated subroutine.
Except that the high-voltage electric field who detects electric power maintenance job site, the safety helmet and the high-voltage electric field early warning device that this application embodiment provided can also carry out safety to job site warning sign and earth connection and inform.
Specifically, in the schematic circuit diagram of the high-voltage electric field early warning device shown in fig. 2, the safety notification to the work site warning board and the ground wire can be realized through the parts of the encoding modulation wave receiver U8, the multi-channel decoding processor U9, the clock chip U3, the memory U4, the memory U5, the voice controller U6, the battery charging and discharging management module U10, and the like.
After the microprocessor U2 is powered on and initialized, when the antenna receives the warning board or the ground wire code modulation wave signal, the signal is modulated by the 14 pin input of the code modulation wave receiver U8 in the wireless receiving circuit and then output from the 10 pin to the 13 pin input of the multi-channel decoding processor U9. The multichannel decoding processor U9 integrates decoding storage output control for a 24-bit code chip, and judges whether the radio signal is compared with the identification data code of the self memory by identifying the address code of the radio signal.
When the received address code is the same, it is determined which set of numbered ground lines or warning boards. Address code and self-identification data code signals are sent to pins 2 and 3 of the microprocessor U2 through the TX, RX ports of the multi-channel decoding processor U9.
The microprocessor U2 is a control core and analyzes the data signal and controls it accordingly. The checksum is calculated to ensure that each set of ground line or warning board data received is error free. After the data is confirmed to be correct, the processor compares the grounding wire or the warning board ID in the data with the grounding wire or the warning board ID value stored in the memory, so as to judge the address code of the numbering grounding wire or the warning board from which the data comes. After the determination, for example, the received first signal is the ground line 060 number. The memory is composed of two U4/U5 pieces with the same 24c512 model, and the memory is provided with different chip addresses, so that the microprocessor can respectively carry out read-write operation on the two memories on the same bus through the difference of the chip addresses. The clock chip U3 reads the time control. The memory and the clock chip are I2c devices, which can share the same data line and clock line, and the pins P1.1 and P1.0 of the I/O port P2 of the microprocessor U2 are used for serial data address and serial clock data exchange of the memory respectively. When accessing the memory, the microprocessor issues a bus enable signal during the high level of the clock line (SCL) to cause the serial data line (SDA) to transition from a high level to a low level. After receiving the enable bit, each memory waits for the receiving microprocessor to send eight bits of addressing data. After each eight-bit data receiving and sending is completed, a receiving party sends a bit of response signal, an addressed memory sends a bit of low level signal to pull down a data line, a host receives the memory data, in the whole communication process, the change of high and low levels on the data line is completed in the period of low level of a clock signal, and the change of voltage on the data line in the period of high level of the clock signal is reserved for indicating the starting and stopping of bus communication. The I/O ports P1.2 and P1.3 of the microprocessor read the CD card playing operation voice command through the serial port control voice module U6, and drive the loudspeaker to give out the notices of 'No. 060 grounding wire installed in the switch cabinet of the street 036 at the overhaul site', 'working here', 'high voltage danger does not come close' and the like. In order to simplify the operation, several function buttons, such as an enter key, a page up key and a page down key, are provided on the I/O ports P3.4, P3.5, P3.7 of the microprocessor.
In the circuit shown in fig. 2, a 3.7V lithium battery is used for power supply, and when a battery charging and discharging management module U10 is selected for output, the maximum voltage difference is 320 MV. The typical value of the quiescent current is 15UA, and the characteristics of easy plugging and unplugging, plug and play, double power supply and the like are adopted by adopting a universal serial USB interface. The U11 realizes protocol conversion between USB and serial I/O ports. On one hand, the chip can receive USB data sent from a PC host, convert the USB data into a serial I/O data format and send the serial I/O data format to the microprocessor. The device is installed at the inside top of safety helmet, including high-voltage electric field detection sensor, shell, circuit board, drain pan.
In order to cooperate with the circuit shown in fig. 2 to normally perform the safety notification of the warning board and the grounding wire in the work site, a grounding wire wireless address coding transmitting circuit and a warning board detecting and transmitting circuit are required to be arranged in the work site.
Fig. 3 shows a ground wire wireless address coding transmitting circuit, which includes a HW1 infrared sensor, a BW1 ground wire detection magnetic control switch, an IC1 signal processing module, an IC2 microprocessor, an IC3 coding module, an IC4WF transmitting module, and an IC5 battery charging and discharging management module.
The IC1 encoding module is decoded by software using EV 1527. The inner code has 20 bits in total, 100 ten thousand groups of inner code combinations can be pre-burned, the repetition probability of the use code is effectively reduced, and the safety is greatly improved. Pin 5 is the high level trigger terminal. The inside is burned with warning board or earth wire address code and self-identification data code. When the maintenance worker walks into the maintenance site, the warning board and the grounding wire can ensure that a group of complete high-frequency radio signals containing address codes and self identification data codes are output, and the receiver can receive correct and complete data. The WF transmitting module modulates the pulse data output by the coding module into a high-frequency signal and transmits the high-frequency signal through the antenna, and the output modulated signal comprises an address code and a data code.
When an operator inserts the grounding rod into the grounding pile, the magnet in the grounding rod is close to the BW1 grounding wire detection magnetic switch, so that the end 7 of the I/O port of the IC2 microprocessor is grounded and jumps to low level. The HW1 infrared sensor detects that the worker activity signal is active. The active signal enters from pin 5 and is output through pin 1 of the signal processing module of IC1, and enters the terminal 6 of the microprocessor of IC2, and the port P3.2 is the access port of the external interrupt 0. When the state of the P3.2 port is changed from '1' to '0', an external interrupt 0 is triggered, the program automatically jumps to an interrupt service program, and is correspondingly controlled by delaying and timing, the output end of the I/O port 18 of the microprocessor triggers the 3 end of the IC3 coding module at a high level, and the coded data pulse train is output from a 4-pin and is input on an ATAD modulator at the 3 end of the IC4WF transmitting module. The modulated high frequency signal is transmitted to the space through the antenna E1. The wireless transmitting frequency adopts 433MHz, and the wireless transmitting module is in a cut-off state when no modulation signal exists.
Fig. 4 shows a warning board detection and transmission circuit.
