[0032] The utility model aims to provide a multi-channel parameter measurement sensor, so as to reduce the labor intensity of operators and realize continuous monitoring.

[0033] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] refer to Figure 1 A multi-channel parameter measurement sensor includes a host 13, multiple laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12 connected to the host 13, the laser gas probes, the carbon monoxide probes 11 and the pipeline extraction multi-parameter sensors 12 regularly and automatically complete the measurement of pipeline parameters, and by setting up multiple laser gas probes, it is possible to achieve simultaneous measurement of multiple monitoring points to reduce the labor intensity of operators, and by setting up laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12, gas, carbon monoxide, flow, temperature, pressure and other parameters in the gas pipeline can be monitored simultaneously, and the parameters that need to be monitored can be automatically and regularly monitored, saving manpower and reducing the labor intensity of operators.

[0035] refer to Figure 2The host 13 includes a shell 14, a metal waterproof joint arranged on the shell 14 and connected to the laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 respectively, a circuit main board 16 arranged inside the shell 14 and electrical components electrically connected to the circuit main board 16. By setting the metal waterproof joint, not only can the waterproof effect be achieved, but also the stable connection between the host 13 and the laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 can be ensured, and setting the circuit main board 16 inside the shell 14 can protect the circuit main board 16 and the electrical components, and prevent dust from entering the circuit main board 16 and reducing the monitoring accuracy.

[0036] refer to Figure 2 and 3 The electrical components include a display screen 18, buttons and a battery pack 15. The display screen 18 and buttons are all arranged on the outer surface of the shell 14 to facilitate the operation of the operator and the on-site observation of data. The display screen 18, buttons and the battery pack 15 are electrically connected to the single-chip microcomputer chip on the circuit main board 16. An NFC module 17 is arranged inside the single-chip microcomputer chip. The single-chip microcomputer chip is connected to the laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 through the RS485 interface respectively, and is used to read the gas, flow and carbon monoxide probe 11 data. A FLASH memory is arranged inside the single-chip microcomputer chip to store the read gas, flow and carbon monoxide probe 11 data. Automatic periodic parameter monitoring of the laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 can be realized through the control of the single-chip microcomputer.

[0037] refer to Figures 1 to 2 The battery pack 15 is electrically connected to the laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 respectively. The laser gas probe, the carbon monoxide probe 11 and the pipeline extraction multi-parameter sensor 12 are powered by the battery pack 15 to provide protection for the normal use of the probe and the sensor. The battery pack 15 is 3 3.7V lithium manganese oxide lithium ion 8Ah batteries connected in series. The battery pack 15 performs double overvoltage and overcurrent protection and is connected in series with a 10Ω / 50W resistor to meet the ia level requirements.

[0038] refer to Figure 3 The battery pack 15 is connected to the single-chip microcomputer chip through an LDO power supply. When the output voltage is close to the output voltage, the conversion efficiency can be improved and the energy consumption can be reduced by setting the LDO power supply.

[0039] refer to Figure 3 The battery pack 15 is connected to the single-chip microcomputer chip through a DC / DC power supply. When the output voltage has a large difference with the output voltage, the conversion efficiency can be improved and the energy consumption can be reduced by setting a DC / DC power supply.

[0040] refer to Figures 1 to 2The number of metal waterproof connectors is not less than the sum of the numbers of laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12, ensuring that the laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12 can be fully connected to the host 13. The laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12 are connected to the metal waterproof connectors through cables, making the connection of the laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12 more reliable and the transmission rate faster.

[0041] refer to Figure 1 There are 10 laser gas probes, which can monitor gas, carbon monoxide, flow, temperature, pressure and other parameters in multiple gas pipelines.

[0042] refer to Figure 3 The NFC module 17 is wirelessly connected to the handheld portable display device, and the data can be monitored through the handheld portable display device, that is, the data can be monitored at any location, which is convenient to use.

[0043] refer to Figure 2 A handle and a lifting lug are provided on the top of the shell 14 to facilitate the placement and fixation of the host 13 at any position.

[0044] The use process of the utility model is as follows:

[0045] Through the above structural setting, when the host 13 is in sleep mode, the LDO power supply and clock chip work to maintain an extremely low standby current, the clock wakes up the microcontroller chip to start working, the microcontroller chip controls the battery pack 15 to work, and then supplies power to each sensor probe in turn. After each sensor probe works stably, the gas, flow, and carbon monoxide probe 11 data are read through the RS485 interface, and the data is stored in the FLASH memory. After all the probe data is read, the host 13 enters sleep mode again and waits for the next detection time to arrive. When the staff needs to read the data, the host 13 is manually woken up. After the data is recorded, the host 13 enters sleep mode.

[0046] The display screen 18 is an LCD display screen. The display screen 18 is displayed when it is triggered externally, that is, when the "wake up" button is pressed. There are 4 buttons, namely "confirm / wake up", "plus", "minus" and "cancel". Press the "confirm / wake up" button and the host 13 is awakened from the sleep state. The display screen 18 displays the password to be entered. The password input is completed by using the "plus" and "minus" keys. After confirming the password, the display screen 18 displays the channel number, monitoring parameter value, unit, time, device address number, etc. Select the corresponding menu to view historical measurement data or change settings. During this period, if the buttons are not operated for a long time, the host 13 will automatically enter sleep.

[0047] When the host 13 is in sleep mode, it is automatically awakened by a timer at regular intervals to determine whether it is time to perform measurement. If it is time to perform measurement, the single-chip microcomputer chip controls the battery pack 15 to work, and the status indicator light is always on, indicating that it is working. The display screen 18 does not display, and the laser gas probe 1#1 is powered on. After waiting for 1 minute for the work to stabilize, the monitoring data is read through the RS485 interface, and the power supply of the laser gas probe 1#1 is turned off. Then, other laser gas probes, carbon monoxide probes 11 and pipeline extraction multi-parameter sensors 12 are powered on, the monitoring parameters are read, and the power supply is turned off. The single-chip microcomputer chip stores the read monitoring parameters in the Flash memory, the status indicator light goes out, and the host 13 enters sleep mode.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
