It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Example 1

Please refer to fig. 1, the utility model discloses a wisdom street facility monitoring devices, including supervisory control computer, removal end, server and if several well lid monitors, the server acquires the well lid information that the well lid monitor passback, and the supervisory personnel can visit the server through supervisory control computer or removal end, obtains the current state of each well lid.

Referring to fig. 2, the manhole cover monitor includes an MCU module, and an inclination sensor, a rupture sensor, a wireless communication module, a buzzer, a biogas concentration sensor, and a water level sensor respectively connected to the MCU module.

The slope sensor is used for (the well lid is prized the in-process, and the well lid can take place the slope) output wake-up signal (normally when opening, monitoring mode is closed to the accessible host computer, and it belongs to prior art, does not do here and give unnecessary details) awakens up the MCU module, the MCU module is awaken the back and is passed through the signal is normally opened on the host computer to wireless communication module, simultaneously, the drive buzzer sounds and reports police, forms deterrent effect to lawless persons. In this embodiment, the wireless communication module is a GPRS module.

The sensor that breaks is used for monitoring whether the well lid breaks, if break, exports wake-up signal promptly and gives the MCU module, the MCU module is uploaded to the host computer to in time overhaul of arrangement personnel.

Besides passive awakening, the MCU module is released from the sleep mode at regular time, the methane concentration in the pipeline is detected through the methane concentration sensor, and the water level in the pipeline is monitored through the water level sensor so that an upper computer can make risk prejudgment in advance.

Referring to fig. 3, the electrical box 1 is mounted below the manhole cover 2. The MCU module, the wireless communication module, the buzzer and the necessary power supply module are all assembled in the electrical box 1. The methane gas concentration sensor 3 and the water level sensor 4 are arranged outside the electric box 1, and the inclination sensor 5 is horizontally arranged below the electric box 1.

Referring to fig. 4, the tilt sensor 5 includes an upper housing 51, a lower housing 52, an upper electrode 53, a lower electrode 54, and a steel ball 55. The upper housing 51 and the lower housing 52 are hermetically connected to achieve waterproofing. The upper electrode 53 is mounted on the top of the inner cavity of the upper housing 51 and is shaped to conform to the top of the inner cavity of the upper housing 51. The lower casing 52 is a conical cylinder with an upward opening, and the lower electrode 54 is mounted at the bottom of the inner cavity of the lower casing 52 and is shaped to fit the bottom of the inner cavity of the lower casing 52. The steel ball 55 is located between the upper electrode 53 and the lower electrode 54. The upper electrode 53, the lower electrode 54 and the steel ball 55 satisfy h1 < d < h2, wherein h1 is the distance between the edge of the lower electrode 54 and the upper electrode 53, h2 is the distance between the center of the lower electrode 54 and the upper electrode 53, and d is the diameter of the steel ball 55. Thus, since the lower housing 52 is a conical cylinder, no matter from which angle the well lid 2 is pried, the steel ball will roll, and the upper electrode 53 and the lower electrode 54 are turned on (the combination of the three is equivalent to a normally open switch) to input a corresponding signal at the corresponding I/O port of the MCU module.

The included angle between the generatrix of the conical cylinder and the horizontal plane is less than 30 degrees. When the included angle is too large, the included angle is not sensitive to the prying angle, and the missed alarm is easy to generate; when the angle is too small, the diameter of the conical cylinder is easy to find out to be too large, and meanwhile, false alarm is easy to occur due to bumping; this embodiment is further preferably 10-15 °. Meanwhile, the diameter d of the steel ball 55 is preferably larger than or equal to 4mm, and the diameter is too small, so that the steel ball 55 is easily jumped up and ejected to the periphery due to bumping when a vehicle passes through the manhole cover 2, and false alarm is caused. Meanwhile, the upper end surface of the upper shell 51 is provided with a buffer rubber 6, and the thickness of the buffer rubber 6 is not less than 3 mm.

Referring to fig. 2 and 5, the rupture sensor 7 is rigidly mounted at the bottom of the manhole cover 2 through a clip 8, a housing of the rupture sensor is an annular glass tube, the glass tube has an entity segment, the entity segment leads out a left electrode 71 and a right electrode 72 to the left and right sides of the entity segment, the glass tube is filled with a conductive medium 73 (the combination of the three is equivalent to forming a normally closed switch) for conducting the left electrode 71 and the right electrode 72, and the conductive medium 73 can be broken along with the rupture of the glass tube.

In this embodiment, the conductive medium 73 may be a flowable conductive medium, such as conductive powder (graphite powder, metal powder, or the like), or may be a conductive liquid. Thus, when the well lid 2 is broken, since the glass tube rigidly connected below the well lid is a brittle material and is broken along with the glass tube, the flowable conductive medium inside the glass tube is lost from the broken part, which causes the left electrode 71 and the right electrode 72 to be disconnected, and a corresponding signal is input to a corresponding I/O port of the MCU module.

Similarly, the conductive medium 73 may also be a brittle material, such as a 1-2mm cast iron wire or graphite core, which breaks when the glass tube breaks.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
