Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0031] Manholes are the core components of urban public infrastructure. They play a vital role in the city's underground, managing and maintaining various important facilities, such as sewage discharge systems, cables for communication networks, gas transmission pipelines, and water supply pipelines. In the prior art, intelligent manholes connect various sensors and single-chip microcomputers through wiring to achieve real-time monitoring of the manhole status. These sensors can detect various parameters in the manhole, such as temperature, humidity, gas concentration, etc., and transmit these data to the single-chip microcomputer, which then determines whether the working status of the manhole is normal based on these data. However, in the prior art, the manhole status is visually and physically inspected by operators. However, in the above-mentioned process of checking the manhole status by operators, it is impossible to detect the manhole status in real time. Therefore, when the manhole status is abnormal, the operator cannot repair it in time, which leads to safety accidents.

[0032] In order to solve the above problems, the present application proposes the following technical concept: the inventors have the idea of ​​deploying corresponding sensors, single-chip microcomputers and safety processing devices on manhole covers and manhole shafts for different detection indicators, such as light intensity or combustible gas concentration in the manhole, to obtain detection data, and send the detection data after analog-to-digital conversion to the single-chip microcomputers connected to the communication of each sensor for further processing and transmission. The safety monitoring device can detect the state of the manhole in real time, effectively preventing safety accidents caused by untimely maintenance by operators.

[0033] The technical solution of the present application is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0034] refer to Figure 1 , Figure 1 A schematic diagram of the structure of a safety detection system for a manhole provided in one embodiment of the present application. In this embodiment, a manhole cover 101 and a manhole shaft 102 are provided in the manhole 10, wherein the manhole cover 101 covers the manhole shaft 102, and the safety detection system includes: at least one sensor 20, a single-chip microcomputer 30 and a safety processing device 40, and the single-chip microcomputer 30 is connected to the sensor 20 and the safety processing device 40 respectively by wireless communication.

[0036] Manhole covers are devices used to seal off pits, which can facilitate the maintenance of underground pipelines and allow operators to enter and exit for inspection and maintenance work. They are usually made of strong materials, such as iron, to withstand the pressure of heavy objects such as vehicles and ensure the safety of pedestrians and vehicles. Manhole covers usually have special patterns or logos, which not only facilitate identification of their functions or municipal departments, but also increase friction to prevent slippery traffic accidents on rainy days.

[0037] The manhole is used to provide a safe working environment in which operators can inspect, repair or perform other necessary operations on the pipeline. Its design ensures that operators can enter and exit easily while also protecting them from direct pressure from vehicles above.

[0038] Among them, at least one sensor 20 is arranged in the manhole 10 to detect the state of the manhole 10 to obtain an analog signal, and send the analog signal to the single-chip microcomputer 30.

[0039] It can be understood that the above-mentioned sensor can be arranged at any position in the cellar, for example, the inner wall of the cellar shaft, the outer wall of the cellar shaft, the inner side of the cellar cover and / or the outer side of the manhole cover.

[0040] Among them, the status of the manhole refers to the internal environment and structural status of the manhole, which may include: the water level in the manhole, the concentration of combustible gas in the manhole, the light intensity in the manhole, and the inclination angle of the manhole cover.

[0041] Among them, analog signals refer to signals that continuously change in time and amplitude, and can express physical quantities such as voltage, pressure, and temperature, and can have an infinite number of different values ​​within a certain time range. In the embodiment of the present application, analog signals are used to represent the state of the manhole in multiple dimensions, including but not limited to: water level in the manhole, concentration of combustible gas in the manhole, light intensity in the manhole, and tilt angle of the manhole cover.

At least one sensor includes at least one of the following: a photosensitive sensor 201, a gas sensor 202, a water level sensor 203 and a posture sensor 204.

[0044] The photosensitive sensor 201 is disposed on the inner wall of the manhole 102 and close to the manhole cover 101, and is used to detect the light intensity in the manhole 102. The photosensitive sensor can use any existing sensor for detecting light intensity, and the embodiment of the present application does not limit the photosensitive sensor.

[0045] When the light intensity in the manhole changes, the photosensitive sensor can detect these changes and convert them into analog signals. These signals are usually continuously changing voltage or current values, which are proportional to the light intensity.

[0046] Among them, the photosensor is located in a dual voltage comparator integrated circuit. The working principle of the circuit is: when the voltage at its input terminal is lower than the reference voltage, the output terminal displays a high level, and when the voltage at its input terminal is higher than the reference voltage, the output terminal displays a low level.

[0047] Specifically, when the light intensity in the manhole does not reach the light intensity threshold, a high level is output; when the light intensity in the manhole exceeds the light intensity threshold, a low level is output.

[0048] The gas sensor 202 is arranged on the inner wall of the manhole and close to the manhole cover, and is used to detect the concentration of combustible gas in the manhole.

[0049] When the concentration of combustible gas in the manhole changes, the gas sensor can detect these changes and convert them into analog signals. These signals are usually continuously changing voltage or current values, which are proportional to the concentration of combustible gas.

[0051] The gas sensor used is the MQ2 sensor. The packaged MQ2 sensor has 6 pins, of which pins 1, 3, and 4 are connected to +5V, and pins 2, 5, and 6 are directly grounded. The gas-sensitive material used in the MQ2 sensor is tin dioxide, and the characteristic of tin dioxide is that the conductivity is relatively low in an environment with good air quality.

[0052] Specifically, when the combustible gas concentration in the manhole does not reach the combustible gas threshold, a high level is output; when the combustible gas concentration in the manhole exceeds the combustible gas threshold, a low level is output.

[0053] The water level sensor 203 is arranged on the outer wall of the manhole and close to the bottom of the manhole, and is used to detect the water level height outside the manhole.

[0056] Among them, the water level sensor is located in the dual voltage comparator integrated circuit. The working principle of the circuit is: when the voltage at its input end is lower than the reference voltage, the output end displays a high level, and when the voltage at its input end is higher than the reference voltage, the output end displays a low level.

[0057] Specifically, when the water level in the manhole does not reach the water level threshold, a high level is output; when the water level in the manhole exceeds the water level threshold, a low level is output.

[0058] The posture sensor 204 is disposed at the manhole cover and is used to detect the tilt angle of the manhole cover.

[0059] Among them, the posture sensor is located in the dual voltage comparator integrated circuit.

[0060] Among them, the attitude sensor model is MPU6050, and the operating voltage is 3.3V+5%, 3.0V+5%, and 2.5V+5%. The attitude sensor also contains a 3-axis gyroscope with a standby current of 5uA and an operating current of 5mA, as well as a 3-axis accelerometer sensor with a range of ±2g, ±4g, ±8g and ±16g and a digital temperature sensor. It also has a second IC interface to connect third-party sensors.

[0061] Among them, the working principle of the circuit is: the gyroscope and accelerometer send the collected analog signals to the microcontroller for analog-to-digital conversion to obtain state parameters. When the state parameters are less than the tilt angle threshold, a high level is output; when the state parameters are less than the tilt angle threshold, a low level is output.

[0062] The single chip microcomputer 30 is arranged at the outer wall of the manhole shaft 102. The single chip microcomputer 30 is used to perform analog-to-digital conversion on the analog signal to obtain state parameters, and control the safety processing device 40 to control the manhole 10 according to the state parameters. The state parameters are used to indicate whether the manhole 10 has an abnormality.

[0063] Among them, the manhole shaft is a structure connecting the manhole cover and the bottom of the manhole. It is usually cylindrical and can be built of bricks, concrete or other materials.

[0064] Among them, the conversion of analog signals to state parameters can be achieved through the processes of sampling, holding, quantization and encoding.

[0065] The state parameters may include: light intensity parameters, gas concentration parameters, water level parameters and / or manhole cover tilt angle parameters.

[0066] The safety processing device may include: an alarm, wherein the alarm may include a buzzer and a prompt light.

[0067] In summary, the present application proposes a safety detection system for manholes, in which a manhole cover and a manhole shaft are provided, wherein the manhole cover covers the top of the manhole shaft; the system includes: at least one sensor, a single-chip microcomputer and a safety processing device, wherein the single-chip microcomputer is respectively connected to the sensor and the safety processing device by wireless communication; wherein at least one sensor is installed in the manhole, for detecting the state of the manhole and generating an analog signal, and sending it to the single-chip microcomputer; the single-chip microcomputer is located on the outer wall of the manhole shaft, responsible for converting the analog signal into a state parameter, and controlling the safety processing device to process the manhole according to the state parameter, so as to indicate whether there is an abnormality in the manhole. By detecting the state of the manhole in real time, safety accidents caused by untimely maintenance by operators are effectively prevented.

[0068] refer to Figure 3 , Figure 3 A schematic diagram of the structure of a safety detection system for a manhole provided in another embodiment of the present application. Figure 1 On the basis of the above, the safety processing device 40 also includes a monitoring terminal 401 which is arranged at a remote end, for example, it can be usually arranged at a remote location such as a control room, a server room or a security monitoring center. The monitoring terminal 401 is used to receive the status parameters sent by the single chip computer 30 through the transmission network 50, and prompt the target personnel to perform safety maintenance on the manhole 10.

[0069] The transmission network 50 includes a router 501 , a coordinator 502 and a base station 503 ; the router 501 is connected to the coordinator 502 for communication, and the coordinator 502 is connected to the base station 503 for communication.

[0070] Among them, a router is an intelligent hardware device that connects two or more networks and acts as a gateway between networks.

[0071] The coordinator may be a ZigBee coordinator.

[0072] Among them, the base station is also called a mobile communication base station, which is the interface device for mobile devices to access the Internet.

[0073] The router 501 is used to receive the state parameters sent by the single chip computer 30 , and send the state parameters to the monitoring terminal 401 via the coordinator 502 and the base station 503 .

[0074] The monitoring terminal may be a mobile phone, tablet or personal computer terminal.

[0075] In summary, the safety processing device is composed of a monitoring terminal, which receives the status parameters sent by the microcontroller through the transmission network including routers, coordinators and base stations, and notifies personnel to maintain the manhole. The hierarchical transmission mechanism ensures the efficiency and reliability of information transmission, and if a part of the transmission network fails, the hierarchical structure helps to quickly locate the problem and simplify the fault detection and repair process.

[0076] refer to Figure 4 , Figure 4 A schematic diagram of the structure of a safety detection system for a manhole provided in another embodiment of the present application. Figure 1 On the basis of Figure 1 The illustrated secure processing device 40 includes an alarm 402 .

[0078] The single chip microcomputer 30 is also used to control the alarm device 402 to issue an alarm when the state parameters are abnormal.

[0079] The alarm may include a buzzer and / or an indicator light.

[0080] Among them, when the single chip microcomputer converts any analog signal obtained from the photosensor, gas sensor, water level sensor and posture sensor into a corresponding low-level digital signal, it indicates that the state parameter is abnormal.

[0081] Specifically, when the microcontroller sends a low-level digital signal to the alarm, the alarm starts working, making a buzzing sound or the indicator light turns on; when the microcontroller converts all analog signals obtained from the photosensitive sensor, gas sensor, water level sensor and attitude sensor into corresponding high-level digital signals, the alarm stops working.

[0082] Among them, the alarm can not only work when it receives a low-level information signal, but also can be reversely controlled by the monitoring terminal.

[0083] The safety processing device 40 includes a drainage device 403 .

[0086] Among them, if the water level sensor fails and the microcontroller cannot be used to control the drainage device to drain water when the water level exceeds the standard, the monitoring terminal can be used to reversely control the drainage device to drain water.

[0087] The system further includes a positioning device 70 , which is disposed at the manhole cover 101 or the manhole shaft 102 , and the positioning device 70 is communicatively connected to the single-chip microcomputer 30 .

[0088] The positioning device may be arranged at any position in the manhole, for example, the inner wall of the manhole shaft, the outer wall of the manhole shaft, the inner side of the manhole cover and / or the outer side of the manhole cover.

[0089] The positioning device 70 is used to obtain the position information of the manhole 10 and send the position information to the monitoring terminal 401 via the single chip microcomputer 30 .

[0090] The purpose of using a positioning device to obtain the location information of the manhole and sending this information to the monitoring terminal is to improve the speed and efficiency of emergency response. After receiving the location information from the positioning device, the monitoring center can quickly dispatch maintenance or rescue personnel to the correct location for processing.

[0091] The system further includes a power storage device 60 , which is any device that can provide electrical energy, such as a solar photovoltaic cell.

[0092] Among them, the power storage device such as solar photovoltaic cell can be arranged above the manhole cover, and a certain thickness of tempered glass is installed above the solar photovoltaic cell.
